Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a support device for supporting a vehicle component reuse system for reusing a powertrain component mounted on a vehicle, a support program for controlling the support device, and a support method.
[0002]
[Prior art]
There are various reasons for the owner of a car to buy a new car. For example, a design change due to a model change or the like is also one of the reasons. Vehicles traded in or purchased at the time of replacement of such vehicles are usually sold on the market as used vehicles, but if the market value of the vehicle is low, it is disposed of.
[0003]
However, components mounted on automobiles, especially powertrain components including an engine, a transmission, a drive shaft, and the like have high durability. The engine parts such as the cylinder head and the cylinder block are not frequently changed in design. For this reason, even if the market value as an automobile is low, there are cases where components mounted thereon can be reused. From the viewpoint of environmental protection, it is desirable to reuse usable parts. Therefore, a system has been considered in which a reusable part (reusable part) is taken out of a car to be disposed of, and the reusable part is used as a replacement part when repairing the car (for example, see Patent Document 1). ).
[0004]
Further, if a new automobile is manufactured by using the reused parts, it becomes possible to provide the user with an inexpensive automobile by reducing the manufacturing cost. Since it is considered that there is also a user need for an automobile using such reusable parts, a system for manufacturing a new automobile using reusable parts is also considered (for example, see Patent Document 2).

[Problems to be solved by the invention]
By the way, a system for manufacturing a new automobile by reusing automobile parts is that a manufacturer manufactures an automobile by reusing automobile parts of an automobile used by a user, and the user uses the manufactured automobile. , A circulating system between the manufacturer and the user. However, due to the following problems, there is a possibility that the system cannot be smoothly circulated.
[0007]
First, in order to reuse a part, it is necessary to evaluate whether the part is reusable, that is, whether the part is reusable. For this purpose, for example, it is conceivable to inspect each part one by one and evaluate its degree. However, inspecting each individual part is extremely complicated and increases the cost required for the operation. For this reason, even if a new automobile is manufactured using reusable parts, the price of the automobile increases, and as a result, the reusable system may not be smoothly circulated.
[0008]
Therefore, it is conceivable to judge the degree of parts based on the mileage and appearance of the vehicle, which is generally performed as an evaluation of a vehicle at the time of trade-in or purchase. However, even if the total mileage is relatively short, if the use condition of the car is poor (for example, when the driving operation of the user is rough), the degree of parts of the car may be bad, and conversely, the total mileage may be small. Even if is relatively long, if the use condition of the car is good (for example, when the driving operation of the user is gentle), the degree of parts of the car may be good. For this reason, it is difficult to accurately evaluate the degree of the components mounted on the vehicle simply based on the traveling distance and the appearance state.
[0009]
In addition, a reusable part is necessary to smoothly circulate the reusable system. The second problem that the system cannot be smoothly circulated is that, as described above, the usage status of the vehicle (such as the driving operation status of the vehicle) by the user affects the quality of the parts. In order to smoothly circulate the reusable system, it is necessary to provide a mechanism for guiding the user so that the use condition of the vehicle is good in order to secure the number of reusable parts.
[0010]
The present invention has been made in view of such circumstances, and an object of the present invention is to provide support for smoothly circulating an automobile component reuse system for reusing powertrain components mounted on an automobile. An object of the present invention is to provide a support program, a support device, and a support method.
[0011]
[Means for Solving the Problems]
The support program according to the present invention is a program for controlling a support device that supports a vehicle component reuse system that reuses powertrain components mounted on a vehicle.
[0012]
The support program stores, in the support device, information on an operation state of the powertrain component, and based on the information stored by the storage process, the powertrain component can be reused. An evaluation value calculation process of calculating a reuse evaluation value, which is an evaluation of the degree, and a notification process of notifying the reuse evaluation value calculated by the evaluation value calculation process at a predetermined time point are executed.
[0013]
According to this configuration, in the storage processing, information related to the operation status of the power train component is stored. As one of the powertrain components, the information related to the operation state of the engine includes, for example, the frequency and time of high-load operation in a cold state, the number of knockings, and the like. That is, in the storage process, information that affects the reusability of the powertrain components is stored.
[0014]
In the evaluation value calculation process, a reuse evaluation value of the powertrain component is calculated based on the information recorded by the storage process. For example, when the frequency of high-load operation during cold operation is high or the time is long, damage to engine parts is relatively large, and the reuse evaluation value is lowered.
[0015]
In the notification process, the reuse evaluation value calculated by the evaluation value calculation process is notified at a predetermined time. When this notification is given to, for example, a car manufacturer, a sales company, or a person in charge of a scrap car yard, the person in charge can grasp the reusable degree of the power train component based on the reuse evaluation value. Since the reuse evaluation value is calculated based on the information on the operation status of the powertrain components, for example, when determining the reusable degree of the powertrain components based on the mileage and appearance of the vehicle. In comparison, the judgment can be made more accurately. Further, it is not necessary to actually check the degree of the power train components, and the trouble is saved accordingly.
[0016]
On the other hand, when the user (owner) of the vehicle is notified of the reuse evaluation value, the user knows the state of the powertrain components mounted on the vehicle used by the user based on the reuse evaluation value. be able to. This makes it possible to expect that the user moderates the driving operation, thereby improving the use condition of the vehicle. As a result, the state of the power train components is suppressed from being reduced, and reusable components are secured. . Thus, the automobile part reuse system smoothly circulates.
[0017]
The above-described notification processing is performed when at least one of the time when the state of the power train components needs to be confirmed, the time when the maintenance of the vehicle is required, and the time when the reuse evaluation value is less than the predetermined value, is performed. What is necessary is just to perform the process which alert | reports an evaluation value.
[0018]
Here, the `` time when it is necessary to check the state of the powertrain parts '' may be, for example, a time when a person in charge of the sales company requests a state check of the powertrain parts in order to perform a trade-in / purchase assessment of the vehicle, A specific example is a point in time when a person in charge of a scrap car garage requests a status check of power train components in order to remove a reusable component from a car to be scrapped. In addition, "when the state of the power train components needs to be confirmed" is, for example, after continuous operation of a predetermined distance or more, or after running for a predetermined distance from the start of the extremely cold start, the power train components are significantly damaged. It may be a point in time when there is a possibility of being performed. In this case, the user of the vehicle may be notified of the reuse evaluation value.
[0019]
As the "time when the maintenance of the car is required", for example, when a predetermined period after the purchase of the car has elapsed, or when the mileage has reached a predetermined distance, such as when a so-called periodic inspection is required, The point at which engine oil and transmission oil need to be changed is mentioned.
[0020]
“When the reuse evaluation value becomes less than the predetermined value” means that the deterioration of the powertrain component is promoted due to the use (running) of the automobile, and the reuse evaluation value is low enough to make it impossible to reuse the component. It may be a time when it becomes. In other words, "the point in time when the reuse evaluation value becomes less than the predetermined value" is the point in time when maintenance such as maintenance of the vehicle is required.
[0021]
The notification process notifies the reuse evaluation value at at least one of the above-described times, and therefore, a car maker, a sales company, or a person in charge of a scrap garage wants to confirm the reusable degree of the power train parts. You can confirm it. In addition, the user of the vehicle is notified of the degree of reusability, thereby increasing awareness of the reuse of parts, and for example, can perform maintenance and improve the use condition of the vehicle.
[0022]
The reuse evaluation value may include an evaluation addition value added when the maintenance is performed, and an evaluation accumulation value obtained by accumulating the evaluation addition values. At this time, the evaluation value calculation process may be a process of calculating the evaluation addition value based on the information stored in the storage process, and setting the evaluation total value to a point for the user of the vehicle.
[0023]
That is, by performing maintenance (including maintenance and replacement of engine oil and the like) of the automobile, deterioration of the state of the powertrain components is suppressed. Therefore, with the execution of the maintenance, the evaluation addition value is calculated based on the information on the operation state of the powertrain component, and the evaluation addition value is accumulated to be the evaluation accumulation value. In this way, the cumulative evaluation value includes two elements, that is, the maintenance state of the vehicle and the operating state of the powertrain components. As a result, the reusability of the powertrain components mounted on the vehicle is accurately evaluated.
[0024]
The cumulative evaluation value is set to points for the user of the vehicle. This point may be, for example, a cashback point when the user purchases a new car. Frequent maintenance of the vehicle and maintenance of the operating state of the power train components in a good condition increase the cumulative evaluation value (points), thereby increasing the user's awareness of the reuse of the components and, for example, promoting the maintenance. And the use of cars can be expected to improve.
[0025]
The evaluation value calculation process may be a process of calculating, based on the information stored by the storage process, an evaluation addition value to be added when the maintenance is performed at the present time before the maintenance is performed. In addition, the notification process may be a process of notifying the evaluation addition value at the time before the maintenance is performed.
[0026]
By doing so, at the time before the maintenance is performed, the evaluation addition value added when the maintenance is performed at that time is reported to, for example, the user of the vehicle. Specifically, at the time of the periodic inspection, the evaluation addition value added when the periodic inspection is performed may be notified to the user of the vehicle. As described above, by notifying the evaluation addition value, it is expected that the user's consciousness is improved and the periodic inspection is performed.
[0027]
Here, the evaluation value calculation process is a process of correcting the evaluation addition value according to the degree of delay when the maintenance is delayed from a preset scheduled maintenance time, and the degree of delay is large. The processing may be such that the evaluation addition value is reduced as much as possible. The above-mentioned "predetermined scheduled maintenance time" may be, for example, the time of periodic inspection.
[0028]
That is, if maintenance is not performed even after the preset scheduled maintenance time, the state of the powertrain components may deteriorate. Therefore, the accuracy of the reuse evaluation value is reduced by lowering the evaluation addition value to be added when performing maintenance at a later time than the evaluation addition value to be added when performing maintenance at the scheduled time. improves. Further, since the points (evaluation added value) added to the user are reduced by delaying the execution of the maintenance, it can be expected that the maintenance is appropriately executed.
[0029]
The evaluation value calculation process may be configured such that the evaluation addition value is reduced as the elapsed time is longer according to the elapsed time from the scheduled maintenance time, or according to the traveling distance after the scheduled maintenance time. The evaluation added value may be set lower as the traveling distance becomes longer.
[0030]
The support program may cause the support device to further execute a prediction process of predicting an evaluation addition value to be added when maintenance is performed at a future time. This notification process may be a process of notifying a predicted value of the evaluation addition value predicted by the prediction process in response to a requested operation.
[0031]
For example, an automobile user may not be able to perform maintenance at this time, but may schedule maintenance at a future time. In such a case, the prediction process predicts an evaluation addition value to be added when maintenance is performed at a future time, and the notification process predicts the evaluation addition value in response to a user operating the support device. Report value. By doing so, the user can grasp the evaluation addition value when the maintenance is executed at a future point in time, and for example, it can be expected that the maintenance is executed early. As a result, the deterioration of the state of the powertrain component is suppressed.
[0032]
The prediction process may be a process of predicting an evaluation addition value to be added when maintenance is performed at a future time, based on history information on a driving operation of the vehicle. Here, the “history information on the driving operation” may be, for example, information on the previous driving operation of the user when climbing a hill or during a cold period. This is information on whether or not there is a tendency to cause damage. In the prediction process, the state of the powertrain component at a future time is determined based on such information, and the evaluation addition value is predicted accordingly. This makes it possible to accurately predict the evaluation addition value.
[0033]
The above-described evaluation value calculation process may be a process of calculating a reuse evaluation value in consideration of a replacement history of a deteriorated part. Here, specific examples of the “deteriorated component” include a lubricating oil of an engine or a transmission, an oil filter, a spark plug of an engine, and the like.
[0034]
By appropriately performing such replacement of the deteriorated component, deterioration of the state of the power train component is suppressed. For this reason, in the evaluation value calculation process, the reuse evaluation value is calculated based on the information on the operation state of the powertrain component and the replacement history of the deteriorated component. This makes it possible to accurately determine the state of the component based on the reuse evaluation value.
[0035]
The above-mentioned evaluation value calculation process is a process of performing a correction to lower the reuse evaluation value as the use period of the vehicle is longer, and performing a correction to lower the reuse evaluation value when the use period of the vehicle is shorter than a predetermined period. Is preferred.
[0036]
In general, the longer a vehicle is used, the more the powertrain components deteriorate, and the less reusable the components become. For this reason, by performing a correction that lowers the reuse evaluation value as the usage period of the vehicle is longer, the degree of the component based on the reuse evaluation value can be accurately determined.
[0037]
However, in this case, the shorter the period of use of the vehicle, the higher the reuse evaluation value, and there is a possibility that replacement of the vehicle may be performed earlier. If the replacement of the car is performed too early in this way, the meaning of the car component reuse system that uses reusable parts from the viewpoint of environmental protection is lost. Therefore, when the usage period of the vehicle is shorter than the predetermined period, a correction for reducing the reuse evaluation value is performed. By doing so, early replacement of the car is suppressed.
[0038]
The above-described evaluation value calculation process may be a process of performing a correction that lowers the reuse evaluation value as the emission performance of the power train is lower.
[0039]
The emission performance of powertrains is improving year by year, and even if a new vehicle is manufactured using reused parts, the new vehicle needs to be adapted to the emission level at the time of manufacture. For this reason, a powertrain component having a high emission performance (conforming to the current emission level) is easy to reuse, while a low emission performance (not conforming to the current emission level). Powertrain components are difficult to reuse. Therefore, the lower the emission performance of the power train, the lower the reuse evaluation value is corrected. By doing so, when the emission performance of the power train is high, the reuse evaluation value is relatively high, and as a result, the reuse rate of the power train component with high emission performance is increased. Thus, the number of vehicles having high emission performance increases, and the emission level of the entire vehicle environment is improved.
[0040]
The support program may cause the support device to further execute an assessment process for calculating an assessment value of a vehicle. At this time, the assessment process may be a process of calculating an assessment amount based on the information about the vehicle and the reuse evaluation value. Here, the "information about the vehicle" may be information generally considered in the assessment of the vehicle, and specifically, the vehicle type, year, mileage, body color, next vehicle inspection Information such as the period up to may be used.
[0041]
In the assessment process, an assessment amount is calculated based on the information on the vehicle and the reuse evaluation value. The reuse evaluation value can evaluate a state of a powertrain component that cannot be accurately determined depending on a traveling distance or an appearance state. For this reason, by calculating the assessment based on the information about the vehicle and the reuse evaluation value, it is possible to calculate an appropriate assessment that reflects the state of the vehicle.
[0042]
In addition, as described above, the reuse evaluation value is set by the driving state of the powertrain component and, consequently, by the driving operation of the user. Therefore, in order to increase the assessed value, it is necessary to improve the usage condition of the vehicle by the user. There is. As a result, the usage of the vehicle is improved, reusable parts are secured, and the reuse system circulates smoothly.
[0043]
The state of the powertrain component is determined based on the reuse evaluation value set as described above, and the reusable powertrain component is removed from the vehicle and reused. At this time, it is necessary to associate the removed part with information on the state of the part.
[0044]
Thus, the support program may cause the support device to further execute a writing process of writing information stored by the storage process into a storage unit attached to the powertrain component. The writing process may be performed in response to the operation of the support device when removing the powertrain component from the vehicle. Further, it is preferable that the information to be written in the storage unit includes not only the information on the operation state of the power train component, but also information such as a reuse evaluation value and replacement history information of the deteriorated component.
[0045]
By doing so, since the information stored by the storage processing is written in the storage unit attached to the powertrain component, it is possible to grasp the state of the component by reading the information. Become. In this way, it is possible to easily manage the parts removed from the automobile and the information on the state of the parts.
[0046]
The support device according to the present invention is a support device for supporting an automobile component reuse system for reusing powertrain components mounted on an automobile.
[0047]
The support device includes a storage unit configured to store information on an operation state of the power train component, and a reuse unit that evaluates a reusable degree of the power train component based on information stored by the storage unit. An evaluation value calculating means for calculating the evaluation value, and a notifying means for notifying the reuse evaluation value calculated by the evaluation value calculating means at a predetermined time are provided. According to this configuration, the same operation and effect as those of the above support program can be obtained.
[0048]
The support method according to the present invention is a support method for supporting an automobile component reuse system for reusing a powertrain component mounted on an automobile.
[0049]
The support method includes: a storage step of storing information on an operation state of the powertrain component; and a reusable evaluation that is a reusable evaluation of the powertrain component based on the information stored in the storage step. An evaluation value calculating step of calculating an evaluation value, and a notifying step of notifying, at a predetermined time, the reuse evaluation value calculated in the evaluation value calculating step are included. According to this configuration, the same operation and effect as those of the above support program can be obtained.
[0050]
Here, the assisting method may further include a writing step of writing information stored in the storage step to a storage unit attached to the power train component, for example, when removing the power train component from the vehicle.
[0051]
In addition, the support method may further include a delivery step of delivering the powertrain component removed from the vehicle to a vehicle manufacturing factory.
[0052]
【The invention's effect】
As described above, according to the support program, the support device, and the support method of the automobile part reuse system of the present invention, the power train component is stored on the basis of the information related to the driving state of the power train component. Is calculated. With this reuse evaluation value, the degree to which the power train components can be reused can be accurately evaluated. Then, at a predetermined time, the calculated reuse evaluation value is notified to an automobile manufacturer, a sales company, or a person in charge of a scrap garage, so that the degree to which the power train components can be reused is appropriately and easily determined. I can figure it out. On the other hand, the reuse evaluation value is notified to the user of the vehicle at a predetermined point in time, so that the use condition of the vehicle can be expected to be good. Parts can be secured.
[0053]
Thus, the automobile part reuse system can be smoothly circulated.
[0054]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0055]
-Embodiment 1-
FIG. 1 is a block diagram according to the automobile part reuse system of the present embodiment. The vehicle component reuse system is a system for manufacturing a new vehicle by reusing powertrain components (engine components in this embodiment) mounted on the vehicle. That is, a sales company that trades in or buys a car used by a user sells the car as a used car when the car can be put on the market as a used car, and sells the car when the market value of the car is low. Send the car to a scrap car yard. At a scrap car yard, when a power train component mounted on the vehicle is reusable, the component (reusable component) is taken out and the taken out reusable component is sent to a car manufacturer. The automobile maker manufactures a new automobile (reused automobile) by using the reused parts and sells the reused automobiles to the user through a sales company. As described above, the automobile part reuse system is configured as a circulation type system between the user and the manufacturer.
[0056]
In the present automobile part reuse system, a reuse evaluation value of the powertrain component is calculated based on the information on the operation state of the powertrain component in order to accurately evaluate the reusability of the powertrain component. It is configured as follows. As will be described in detail later, the reuse evaluation value includes an evaluation addition value and an evaluation cumulative value obtained by accumulating the evaluation addition value. At the time of execution, etc.), it is set based on the information on the operation state of the powertrain component.
[0057]
By calculating such a reuse evaluation value, a sales company, a scrap car yard, and an automobile manufacturer can easily and accurately determine whether or not a power train component can be reused based on the reuse evaluation value. It can provide a user with a parts-reuse vehicle at low cost.
[0058]
The reuse evaluation value (cumulative evaluation value) is also set as a cashback point when the user purchases a new car, for example. As described above, the cumulative evaluation value increases as a result of maintenance of the vehicle, and fluctuates in accordance with the information on the operation state of the powertrain components and, in turn, the usage state of the vehicle. For this reason, in order to increase the evaluation cumulative value, in other words, to increase the cashback point, the user must appropriately perform maintenance and maintain a normal driving condition of the automobile. Since the user has the merit of cashback, the user is conscious of the driving operation and the maintenance that increase the cumulative evaluation value, thereby suppressing the deterioration of the state of the powertrain components. As a result, the number of reusable parts increases.
[0059]
Thus, in the present embodiment, the automobile parts reuse system is smoothly circulated. Hereinafter, a support device and a support method for supporting the above system will be described with reference to the drawings.
[0060]
FIG. 2 shows a configuration of the on-vehicle PC 1 as a support device for supporting the above-mentioned automobile part reuse system. The in-vehicle PC 1 is mounted on an automobile.
[0061]
The in-vehicle PC 1 includes, for example, a liquid crystal display unit, a display unit 11 for displaying (notifying) various information to the user, an operation input unit 12 for performing various input operations by the user, and various information as described later. And a storage unit 13 for storing support programs, and a CPU 14 for controlling the above-described units in accordance with the support programs. Various information such as the total mileage of the vehicle is input to the in-vehicle PC 1 in addition to the information on the operation state of the power train components from the engine controller 2 described later.
[0062]
An engine controller 2 is connected to the in-vehicle PC 1. The engine controller 2 controls the engine 3 as one of the power train components, and is configured to control the engine 3 based on water temperature and other various control information.
[0063]
The engine controller 2 is configured to sequentially store the operating state of the engine 3, and is configured to transmit the stored operating state to the in-vehicle PC 1 in response to a request from the in-vehicle PC 1. I have. That is, the engine controller 2 also functions as a storage unit that stores information on the operation state of the powertrain component (engine component 3).
[0064]
An IC chip 33 is attached to each of the cylinder head 31 and the cylinder block 32 constituting the engine 3. The IC chip 33 is a chip capable of writing information and a chip capable of reading the written information. The information is written into the IC chip 33 by the in-vehicle PC 1 when the engine 3 is detached from the car. The details will be described later.
[0065]
Next, control of the CPU 14 in the in-vehicle PC 1 will be described with reference to flowcharts shown in FIGS.
[0066]
In this flowchart, steps S11 to S19 and step S112 are steps relating to calculation and notification of a reuse evaluation value (evaluation addition value and evaluation cumulative value), and steps S110 and S111 are a reuse evaluation value (evaluation addition). ), And steps S113 to S116 are steps related to the assessment of the vehicle.
[0067]
Steps S11 to S19 basically calculate an evaluation addition value to be added when maintenance is performed at the time when maintenance is to be performed (periodic inspection time or the like), and the calculated value is calculated by the user. And prompting the user to perform maintenance.
[0068]
The evaluation addition value is calculated by multiplying a basic addition value set for the execution of maintenance by coefficients K1 to K5 set based on various information.
[0069]
First, in step S11, various data required in the following steps are input, and in subsequent step S12, it is determined whether or not it is time to perform maintenance on the vehicle. Here, the time when the maintenance is required may be, for example, the time for periodic inspection of the automobile. Specifically, the time may be six months after the purchase of the car, one year after the purchase, or the like. Further, instead of the elapsed time after the purchase of the car, the total travel distance of the car may reach 1000 km, may reach 3000 km, or the like. Further, the time when the maintenance is required may be the time when the deteriorated parts such as the engine oil need to be replaced. When YES is determined as the maintenance time in step S12, the process proceeds to step S14, and when NO is determined as the maintenance time, the process proceeds to step S13.
[0070]
In step S13, it is determined whether the operation input unit 12 of the in-vehicle PC 1 has performed an operation for requesting confirmation of the reuse evaluation value (evaluation addition value). When YES is determined to have been performed, the process proceeds to step S14, and when NO is determined to be performed, the process returns. That is, when the maintenance of the vehicle is not required, but the user of the vehicle wants to check the evaluation addition value to be added when the maintenance is performed at the present time, the operation input unit 12 of the in-vehicle PC 1 is operated. It is configured so that it can be confirmed by operation.
[0071]
In step S14, the excess traveling distance at the present time is calculated, and the coefficient K4 is set according to the excess traveling distance. The excess traveling distance is a distance obtained by subtracting the traveling distance at the time when maintenance is required from the current traveling distance. That is, the excess mileage means the mileage traveled after the maintenance required time. The coefficient K4 may be, for example, 1.0 when the above-mentioned excess traveling distance is less than 2000 km, 0.9 when it is 2000 km or more and less than 4000 km, and 0.8 when it is 4000 km or more. That is, it is preferable that the coefficient K4 be reduced as the excess traveling distance increases. In this manner, when maintenance is performed at the time when maintenance is required, the coefficient K4 is 1.0, and the evaluation addition value remains unchanged. However, the later the maintenance is actually performed, the smaller the coefficient K4 becomes. Therefore, the evaluation addition value decreases.
[0072]
In the following step S15, a coefficient K3 is set according to the information on the operating state of the engine 3 during the latest cold. Specifically, based on the operating state information transmitted from the engine controller 2, the number of knocking occurrences and / or the accumulated time of the high-load operating state during the latest (for example, the latest one month) cold period is calculated. Then, it determines which rank the calculated number of times and / or integrated time belongs to, for example, about three ranks, and sets a coefficient K3 according to the rank to which the rank belongs. For example, K3 is set to 0.8 when the degree is the worst (the number of times is large and the integration time is long), K3 is set to 0.9 when the degree is medium, and K3 is set to 1.0 when the degree is good. That is, the coefficient K3 is made smaller and the evaluation addition value is made lower when the engine is in an operating state in which damage to the engine parts is large.
[0073]
In step S15, the coefficient K3 is set based on only the operation state information of the engine at the time of cold, but the coefficient K3 may be set in consideration of the operation state information at the time of warm. However, since the operating state in the cold state has a greater effect on the state (degree) of the engine components, the coefficient K3 may be set by weighting the operating state information in the cold state.
[0074]
In step S16, a coefficient K1 is set based on the information on the period of use of the vehicle. Specifically, the coefficient K1 is set to 0.7 when the use period is 10 years or more, and is set to 1.0 when the use period is 3 years or more and less than 10 years. When the usage period is less than three years, the coefficient K1 is set to 0.9. As described above, when the usage period of the vehicle is long, the evaluation addition value is reduced by reducing the coefficient K1. In this way, the longer the use period, the more the components deteriorate, and the reuse rate of the components decreases, but the reuse evaluation value can be made to correspond thereto. In addition, the lower the evaluation addition value, the cumulative evaluation value, that is, the cashback point does not increase, which also leads to prompting the user to replace the car early.
[0075]
On the other hand, when the usage period is too short, the coefficient K1 is reduced to lower the evaluation addition value. This is because if the evaluation addition value is increased when the usage period is short and the cumulative evaluation value is high, the replacement of the vehicle may be performed in an extremely short usage period. In other words, when the usage period is 3 years or more and less than 10 years, the replacement period of the vehicle is promoted during this period because the period is suitable for replacement of the vehicle and the reuse ratio of the parts of the vehicle is high. To this end, the coefficient K1 is set.
[0076]
In step S16, the coefficient K1 may be set according to the total mileage of the vehicle instead of the usage period. For example, when the total traveling distance is less than 30,000 km, the coefficient K1 is 0.9, and when the total traveling distance is 30,000 km or more and less than 100,000 km, the coefficient K2 is 1.0, and the total traveling distance is 100,000 km or more. At times, the coefficient K2 may be set to 0.8.
[0077]
In step S17, a coefficient K2 is set according to the emission performance level of the engine 3. For example, when the emission control level of the engine 3 is 3 stars, the coefficient K2 is 1.0, when it is 2 stars, the coefficient K2 is 0.9, and when it is 1 star, the coefficient K2 is 0.8. And
[0078]
This is because when a new engine is manufactured by reusing engine parts, the manufactured engine needs to be adapted to the emission level at the time of manufacturing. Engine parts that meet the current emission level are easy to reuse, whereas engine parts that do not meet the current emission level are difficult to reuse. Therefore, when the emission performance of the engine 3 is high, the coefficient K2 is increased, and when the emission performance is low, the coefficient K2 is reduced. By doing so, the reuse rate of parts of the engine with high emission performance is increased, and as a result, even if a new automobile using the parts is manufactured, the number of automobiles with high emission performance increases.
[0079]
In step S18, a coefficient K5 is set according to the replacement frequency of the deteriorated part. Here, the deteriorated parts mean engine oil, transmission oil, spark plugs, and the like. The appropriate replacement frequency of these deteriorated parts differs depending on the use condition (such as mileage) of the vehicle. Therefore, for example, an exchange frequency standard is set according to the traveling distance, and the coefficient K5 is set to 1.1 when the actual exchange frequency is larger than the set exchange frequency standard, and the coefficient K5 is set to 1 when the actual exchange frequency is small. .0. Further, the coefficient K5 may be set according to whether or not the replacement of the deteriorated part is performed regularly. The replacement information of the deteriorated part may be stored in the storage unit 13 by operating the operation input unit 12 of the in-vehicle PC 1 when the replacement of the part is performed.
[0080]
In step S19, an evaluation addition value is calculated. Specifically, the evaluation addition value is calculated by multiplying the basic addition value set for the execution of the maintenance by each of the coefficients K1 to K5. That is, the basic addition value × k1 × k2 × k3 × k4 × k5 → the evaluation addition value.
[0081]
In step S110, it is determined whether or not an operation for requesting prediction of an evaluation addition value has been performed by the operation input unit 12 of the in-vehicle PC 1, and if YES has been performed, the process proceeds to step S111, while NO has been determined. If so, the process proceeds to step S112. This is provided for a user who cannot perform maintenance at the present time, and when the user wants to check the value of the evaluation addition value when the maintenance is performed in the future, the operation input of the in-vehicle PC 1 is performed. By operating the unit 12, it can be confirmed.
[0082]
In the above step S111, an estimated value to be added when maintenance is executed at a future time is predicted. For example, it is only necessary to predict the evaluation addition value when the maintenance is performed when the vehicle travels 2000 km and the evaluation addition value when the maintenance is performed when the vehicle travels 4000 km.
[0083]
When estimating the evaluation addition value, the coefficient K4 set in step S14 may be reset according to the excess traveling distance at a future time point (at the time of traveling 2000 km or 4000 km). In addition, when estimating the evaluation addition value, information on the driving operation of the vehicle by the user so far is considered. For example, when there is a tendency for a driving operation to damage components based on a tendency of the driving operation during a climb or a cold time, the predicted value of the evaluation addition value is reduced. This makes it possible to accurately predict the evaluation addition value.
[0084]
In step S112, the evaluation addition value calculated in step S19 and the evaluation total value obtained by accumulating the reuse evaluation values, that is, the cashback point, are displayed on the display unit 11 of the in-vehicle PC 1. At this time, when the evaluation addition value is predicted in step S111, the prediction value is also displayed. Thereby, the user can confirm the cashback point added when the vehicle is maintained at the present time and the cumulative cashback point reached by adding the cashback point. As a result, the maintenance is encouraged, and the state of the engine components can be maintained in a good condition.
[0085]
In the following step S113, it is determined whether or not the vehicle assessment confirmation operation has been performed by the operation input unit 12 of the in-vehicle PC 1, and if NO has not been performed, the process returns as it is, whereas if YES, the operation has been performed. Move to step S114.
[0086]
In the above step S114, an assessment program is executed to calculate the assessment value of the vehicle. Here, the above-mentioned assessment program, as generally performed in the assessment of automobiles, calculates the assessment amount based on information such as the type of car, year, mileage, body color, period until the next inspection, etc. calculate.
[0087]
In the next step S115, the assessed amount calculated in step S114 is corrected according to the cumulative evaluation value. Specifically, when the cumulative evaluation value is relatively high, the assessment value is increased because the condition of the engine component is good, while when the cumulative evaluation value is relatively low, the assessment value is poor because the condition of the engine component is poor. Correction to lower the Then, in step S116, the corrected purchase assessment amount is displayed on the display unit 11 of the in-vehicle PC 1.
[0088]
In this way, by notifying the user of the vehicle about regularly the evaluation addition value and the cumulative evaluation value, the user's consciousness is improved, and good driving operation and maintenance such that the state of the engine parts does not deteriorate are improved. Execution can be expected.
[0089]
Then, when the user actually performs the maintenance of the vehicle, the person in charge of the sales company that has performed the maintenance operates the operation input unit 12 of the in-vehicle PC 1 to input that the maintenance has been performed. The in-vehicle PC 1 calculates an evaluation addition value in accordance with the input, updates the reuse evaluation value (evaluated cumulative value), and stores the updated evaluation value in the storage unit 13.
[0090]
Next, when the sales company purchases or trades in the automobile, for example, the person in charge operates the in-vehicle PC 1. As a result, the CPU 14 of the in-vehicle PC 1 reads the reuse evaluation value (cumulative evaluation value) stored in the storage unit 13, the information on the total mileage, the operation state of the engine 3, and the like, and displays the information on the display unit 11. Display information about This allows the person in charge to determine the purchase / trade valuation with reference to the reuse evaluation value.
[0091]
If the information stored in the in-vehicle PC 1 is stored in an external PC installed outside the vehicle, the sales company staff operates the in-vehicle PC 1 instead of operating the in-vehicle PC 1. This makes it possible to confirm the reuse evaluation value. For example, each time a sales company performs maintenance on an automobile, an external PC may be connected to the in-vehicle PC 1 and information stored in the storage unit 13 of the in-vehicle PC 1 may be transferred to the external PC. Further, the on-vehicle PC 1 is configured to be connectable to an external PC via a wired or wireless communication line, and for example, every time the information stored in the storage unit 13 is updated, the updated information is stored in the external PC. May be transferred to
[0092]
When the vehicle is purchased or traded in, the cumulative evaluation value of the vehicle is managed as a user's cash back point by a device different from the vehicle-mounted PC 1 (for example, an external PC installed at a sales company or a vehicle manufacturer). do. The purchased or traded-in car is usually sold as a used car, but when the market value of the car is low, the car is sent to a scrap car yard and discarded. Also at the time of carrying out this scrap car disposal, the person in charge of the scrap car yard operates the in-vehicle PC 1. As a result, the CPU 14 of the in-vehicle PC 1 displays information such as the reuse evaluation value (evaluated cumulative value) stored in the storage unit 13 on the display unit 11. The person in charge determines whether or not the engine component can be reused based on the reuse evaluation value or the like displayed on the display unit. When the engine 3 can be reused, the engine 3 is removed from the automobile. Before the engine 3 is removed, the engine 3 is stored in the storage unit 13 by operating the vehicle PC 1 as shown in FIG. Is transferred to the IC chip 33 attached to the cylinder head 31 and the cylinder block 32 (see the solid line arrow in the figure, and in the figure, the movement of the information is indicated by the solid arrow and the movement of the parts is indicated by the solid arrow). As indicated by white arrows). Here, the information transferred to the IC chip 33 can determine the state of the engine 3 such as the total mileage, the reuse evaluation value (evaluated cumulative value), the replacement history of the deteriorated parts, the operation information of the engine 3, and the like. Information may be used.
[0093]
In this way, the engine itself removed from the vehicle has the information related to the reuse determination. For example, when assembling the engine 3 into a new vehicle, the information stored in the IC chip 33 is used. By reading, it becomes possible to confirm the state of the component.
[0094]
When the engine 3 thus removed can be reused as it is, the engine 3 is transported to the manufacturer as it is. The manufacturer reuses the engine 3 to manufacture a new automobile. At the time of this manufacturing, information on the IC chip 33 attached to the engine 3 is read as necessary, and the state of the engine 3 is confirmed.
[0095]
On the other hand, the engine 3 is not reusable, but when some engine parts such as the camshaft 34 and the valve 35 are reusable, the engine 3 is further disassembled to make reusable parts. Take out. Thus, when the reusable camshaft 34 or valve 35 is taken out from the engine 3, it is necessary to manage the camshaft 34 or valve 35 and the information on the state in association with each other.
[0096]
Here, since the engine parts such as the camshaft 34 and the valve 35 are many in number, relatively small and are exposed to high temperatures, it is necessary to mount the IC chip 33 like the cylinder head 31 or the cylinder block 32. Is generally difficult. Then, the IC chip 43 is attached to the pallets 41 and 42 used when the taken-out camshaft 34 and valve 35 are carried. The pallets 41 and 42 may be the pallets 41 on which one component is placed, or the pallets 42 on which a plurality of components are placed. Then, the information stored in the IC chip 33 of the cylinder head 31 is written in the IC chip 43 of the pallets 41 and 42. At this time, the information to be transferred to the IC chips 43 of the pallets 41 and 42 includes information that enables the state of the engine components to be determined and that the engine components (here, the camshaft 34 and the valve 35) are attached to the engine 3. May be used as information for specifying The information for specifying that the camshaft 34 and the valve 35 have been attached to the engine 3 may be, for example, information on a lot number of the camshaft 34 and the valve 35 and information on a date when these are removed from the engine 3.
[0097]
On the other hand, the lot number and the date information removed from the engine 3 are written in the components 34 and 35 placed on the pallets 41 and 42, respectively. By doing so, the information written in the IC chip 43 can be compared with the component. As a result, for example, even when the parts 34, 35 on the pallets 41, 42 have been replaced, it is immediately known that the parts are mounted on a car while the state of the engine parts is erroneously recognized. It can be prevented beforehand.
[0098]
Here, as a method for writing information to the engine parts, for example, a seal on which the information is written may be attached to the camshaft 34 or the valve 35. At this time, a seal, such as a seal, which cannot be reattached once the mark is lifted off, such as a seal seal, may be attached to the camshaft 34 or the valve 35 so that the information is not falsified.
[0099]
Further, information may be directly written to the camshaft 34 and the valve 35 by an ink-jet printing method. In this case, for example, it may be difficult to recognize that the information is written on the component by using an ultraviolet light emitting type ink.
[0100]
Thus, the reusable parts are conveyed to the manufacturer while being placed on the pallets 41 and 42, and the manufacturer reuses the engine parts and manufactures a new automobile. At the time of this manufacturing, the information of the IC chip 43 attached to the pallets 41 and 42 is read as necessary, and the state of the components 34 and 35 is confirmed.
[0101]
As described above, in the first embodiment, the reuse evaluation value of the engine component is calculated based on the information related to the operation state of the engine (Step S12). Since the reuse evaluation value is used for, for example, trade-in / purchase, taking out parts from a car, and attaching parts to a new car, a person in charge of a sales company, a scrap car yard, or a car maker. Can appropriately and easily grasp the degree to which parts can be reused.
[0102]
On the other hand, the user of the vehicle is notified of the reuse evaluation value at each time when maintenance is required (periodical inspection time), so that the user's consciousness is improved, and as a result, the deterioration of the state of the engine parts is suppressed, Reusable parts can be secured.
[0103]
Thus, the automobile part reuse system can be smoothly circulated.
[0104]
In the flowchart shown in FIG. 3, the evaluation is performed when the maintenance of the vehicle is required (step S12) and when the confirmation request operation of the reuse evaluation value (evaluation added value) is performed (step S13). Although the addition value is calculated, for example, after a continuous operation for a predetermined distance or more, or after traveling a predetermined distance from the start of the extremely cold start, there is a possibility that the engine parts may be significantly damaged. The addition value may be calculated, and this may be reported to the user.
[0105]
-Embodiment 2
The second embodiment differs from the first embodiment in the control of the CPU 14 in the in-vehicle PC 1. In the first embodiment, at the time when the maintenance of the vehicle is necessary, the evaluation addition value to be added when the maintenance is performed at that time is calculated, and the calculated value is notified to the user. On the other hand, in the second embodiment, the user is notified when the evaluation addition value becomes smaller than the predetermined value, thereby prompting the user to perform maintenance.
[0106]
Next, control of the CPU 14 in the in-vehicle PC 1 according to the second embodiment will be described with reference to flowcharts shown in FIGS. Note that parts different from the control of the CPU according to the first embodiment will be particularly described in detail, and the same parts will be briefly described.
[0107]
This control flow may be started at a predetermined cycle. First, in step S21, various data required in the following steps are input, and in the following step S22, the current maintenance distance is calculated based on the traveling distance at the present time. By subtracting the traveling distance at the time of performing the above, the traveling distance after the previous maintenance is calculated. Then, the coefficient K4 is set according to the traveling distance. The coefficient K4 decreases as the travel distance increases, as in the first embodiment.
[0108]
In a succeeding step S23, based on the reading of the operating state information transmitted from the engine controller 2, the number of times of knocking occurrence and / or the accumulation of the high-load operating state in the latest cold state (for example, for the last seven days during which the vehicle has run) has been cold recently. The coefficient K3 is set according to time. Note that the coefficient K3 may be set in consideration of the operating state information at the time of warming, as in the first embodiment.
[0109]
In step S24, the coefficient K1 is set based on the information on the period of use of the vehicle, in step S25, the coefficient K2 is set according to the emission performance level of the engine, and in step S26, the coefficient K1 is set according to the frequency of replacement of the deteriorated parts. Set the coefficient K5.
[0110]
Then, in step S27, the evaluation addition value in the case where the maintenance is executed at the present time is calculated based on the coefficients K1 to K5 set in the above steps S22 to S26.
[0111]
In step S28, it is determined whether or not the evaluation addition value calculated in step S27 is less than a predetermined value. In other words, this is to determine whether it is time to perform the maintenance.If the evaluation addition value is less than the predetermined value, if the maintenance execution time is further delayed, the degree of the parts may deteriorate. Means On the other hand, when the evaluation addition value is equal to or more than the predetermined value, even if the maintenance execution time is delayed, the degree of the components does not deteriorate. When the result of step S28 is YES, the process proceeds to step S212, while when the result is NO, the process proceeds to step S29.
[0112]
In step S29, it is determined whether the operation input unit 12 of the in-vehicle PC 1 has performed an operation for requesting confirmation of a reuse evaluation value (evaluation addition value). When YES is determined to have been performed, the process proceeds to step S210, and when NO is determined to be performed, the process returns.
[0113]
In step S210, it is determined whether or not an operation for requesting a prediction of an evaluation addition value has been performed by the operation input unit 12 of the in-vehicle PC 1, and if YES has been performed, the process proceeds to step S211 while NO has been determined. If, the process proceeds to step S212.
[0114]
In step S211 described above, the evaluation addition value to be added when the maintenance is performed at a future time is predicted, and in step S212, the evaluation addition value calculated in step S27 and the evaluation cumulative value obtained by accumulating the reuse evaluation value are calculated. The value (cashback point) is displayed on the display unit 11 of the in-vehicle PC 1. At this time, when the evaluation addition value is predicted in step S211, the predicted value is also displayed.
[0115]
Steps S213 to S216 are the same as steps S113 to S116 in the first embodiment, and thus description thereof will be omitted.
[0116]
As described above, in the second embodiment, the time at which maintenance is required is set based on the reuse evaluation value (evaluation addition value), and at that time, the user is notified of the reuse evaluation value, and the maintenance is encouraged. For this reason, since maintenance is performed in accordance with the usage state of the vehicle by the user, it is possible to effectively suppress the deterioration of the state of the engine parts, and to sufficiently secure reusable parts. Can be. In addition, such notification can be expected to make the driving operation of the user gentle, and for example, the frequency of sudden acceleration is reduced, which leads to environmental improvement.
[0117]
