Description

  The present invention relates to a technique for providing information related to refueling.

  Some navigation systems not only guide the vehicle, but also guide facilities along the road and facilities around the vehicle. In particular, there is a navigation system that guides a gas station in order to perform refueling necessary for traveling of a vehicle.

  When guiding a gas station (hereinafter referred to as “the station” where appropriate), the fuel price is an important factor, and therefore, a fueling instruction device has been proposed that guides the cheapest station within the cruising range (for example, Patent Literature) 1).

JP 2003-294458 A

  However, the technique described in Patent Document 1 provides information focusing on the fuel price, and even if refueling at the lowest price is possible by this technique, energy saving may not always be achieved. This is because the fuel quality (an index indicating the travel distance per unit capacity) may be deteriorated due to the quality of the fuel.

  The present invention has been made to solve the above-described problems, and its object is to provide fuel supply information including an economic viewpoint in consideration of fuel consumption caused by different fuel quality for each stand. There is.

  The fuel supply information providing system made to achieve the above object includes a center (20) and a fuel supply information providing device (10) mounted on a vehicle. The center stores fuel consumption statistical information capable of calculating the estimated fuel consumption of each oil type for each of a plurality of stations. The fuel supply information providing apparatus is configured to be capable of data communication with the center.

Here, either one of the center and the fuel supply information providing device includes estimated fuel consumption calculation means (11a). The refueling information providing apparatus includes information providing means (11b).
The estimated fuel consumption calculation means calculates an estimated fuel consumption for each stand based on the fuel consumption statistical information. The information providing means provides refueling information including the estimated fuel consumption calculated by the estimated fuel consumption calculating means.

In this way, fuel consumption due to different fuel qualities for each stand is taken into consideration, and fuel supply information including an economic viewpoint can be provided.
The estimated fuel consumption calculating means may be provided in the fuel supply information providing device. In this case, the estimated fuel consumption calculation means may be configured to acquire fuel consumption statistical information from the center and calculate an estimated fuel consumption for each stand based on the actual fuel consumption in the vehicle. In this way, a value considering the actual fuel consumption of the vehicle can be calculated as the estimated fuel consumption.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
The navigation system shown in FIG. 1 includes a navigation device 10, a center 20, and an injection device 30. This navigation system is an example of a fuel supply information providing system according to the present invention.

  The navigation device 10 is mounted on a vehicle and is configured around a control unit 11. The control unit 11 is configured as a so-called computer system, and includes a CPU, a ROM, a RAM, an I / O, and a bus line connecting them. The navigation device 10 is an example of a fuel supply information providing device according to the present invention.

The control unit 11 is connected to a position detection unit 12, an operation unit 13, a map data acquisition unit 14, an audio output unit 15, an image display unit 16, a communication unit 17, and an input / output I / F 18.
The position detection unit 12 includes a GPS (Global Positioning System) receiver, a geomagnetic sensor, a gyroscope, and the like. The GPS receiver receives a transmission signal from a GPS artificial satellite and detects the position coordinates and altitude of the vehicle. The geomagnetic sensor detects the direction of the vehicle by geomagnetism. Furthermore, the gyroscope outputs a detection signal corresponding to the angular velocity of the rotational motion applied to the vehicle. The position detection unit 12 detects the current position of the vehicle.

  The operation unit 13 is configured to input various instructions from the user, and is embodied as a physical push button switch or the like. Alternatively, it may be embodied as a touch panel configured integrally with the image display unit 16.

  The map data acquisition unit 14 is configured to input map data to the control unit 11. The map data is stored in a DVD-ROM or the like and is input to the control unit 11 via the map data acquisition unit 14. Of course, an HDD or a CD-ROM may be used in addition to the DVD-ROM. The map data includes road data, drawing data, map matching data, route guidance data, and the like.

The audio output unit 15 includes a speaker or the like. The voice output unit 15 can provide voice information to the user.
The image display unit 16 is configured to display a map and various information. Specifically, it is configured using a display device such as a liquid crystal.

The communication unit 17 is configured to perform data communication with the center 20. The input / output I / F is a configuration for inputting / outputting data to / from the injection device 30.
The control unit 11 performs route guidance processing as navigation-related processing. The route guidance process calculates a route from the current position of the vehicle to the destination set by the operation of the operation unit 13 by the user based on the map data input from the map data acquisition unit 14, and calculates the current position and the purpose. This is a process for displaying the route to the destination on the image display unit 16 in consideration of the relationship with the ground route and performing the travel guidance. As a method for automatically setting an optimum route, a method such as cost calculation by the Dijkstra method is known.

  The center 20 exists outside the vehicle on which the navigation device 10 is mounted, and performs data communication with the navigation device 10 via the communication unit 17 of the navigation device 10. The center 20 includes a center side control unit 21 and a database 22.

  Similar to the control unit 11, the center side control unit 21 is configured as a so-called computer system. Information transmitted from the navigation device 10 is registered in the database 22 as described later.

  The injection device 30 has a gasoline injection ECU 31 and a gasoline injection injector 32. The gasoline injection injector 32 is provided corresponding to the cylinder, and injects a mixture of gasoline into the cylinder. The gasoline injection ECU 31 controls the gasoline injection by the gasoline injection injector 32.

Next, the fuel supply determination process will be described based on the flowchart of FIG. This refueling determination process is repeatedly executed by the control unit 11 of the navigation device 10.
In the first S100, the amount of residual oil is acquired. This process acquires the amount of fuel remaining in the vehicle fuel tank.

  In S110, it is determined whether or not refueling has been performed. This process is such that, for example, an affirmative determination is made when the amount of residual oil acquired in S100 increases. When it is determined that the fuel has been supplied (S110: YES), the process proceeds to S120. On the other hand, when it is determined that refueling has not been performed (S110: NO), the subsequent processing is not performed and the refueling determination processing is terminated.

In S120, position information is acquired. This process acquires the current position of the vehicle based on information from the position detection unit 12.
In subsequent S130, the gas station is specified and stored. This process specifies and stores the refueling gas station based on the position information acquired in S120. In the next S140, the refueling date is stored.

That is, by the processing of S130 and S140, the refueling date and the refueling gas station are stored in association with each other.
Therefore, in S150, it is determined whether or not the gas station that has been refueled this time and the gas station that has been refueled the same time are the same station. If it is determined that they are the same stand (S150: YES), the process moves to S160. On the other hand, when it is determined that they are not the same stand (S150: NO), the process proceeds to S170.

  In S160, it is determined whether or not the oil type has been changed. In this embodiment, “Regular”, “Mid-grade”, “Rremium”, and “Diesel” are prepared as oil types. It is assumed that the oil type information is input in advance by the user via the operation unit 13. In general, the oil type is rarely changed, but when changing the oil type such as “Regular” → “Premium”, the user inputs the oil type information again at the time of refueling. If it is determined that the oil type has been changed (S160: YES), the process proceeds to S170. On the other hand, if it is determined that the oil type has not been changed (S160: NO), the host vehicle is set as a probe car in S180, and then the fuel supply determination process is terminated.

  If it is not refueling at the same stand or if the oil type is changed, it is determined whether or not sufficient refueling has been performed in S170. This determination is made based on whether or not there is a fuel supply equal to or greater than a predetermined threshold percentage because it can be determined from what change in the amount of residual oil acquired in S100 that fuel supply corresponds to the fuel tank. If it is determined that sufficient refueling has been performed (S170: YES), the host vehicle is set as a probe car in S180, and then the refueling determination process ends. On the other hand, when it is determined that sufficient fuel supply has not been performed (S170: NO), the process of S180 is not executed, and the fuel supply determination process ends.

Next, information transmission processing will be described based on the flowchart of FIG. This information transmission process is repeatedly executed while the ignition switch is on.
In first S200, it is determined whether or not there is a probe car setting. Here, an affirmative determination is made when the host vehicle is set as a probe car in S180 in FIG. If it is determined that there is a probe car setting (S200: YES), the process proceeds to S210. On the other hand, if it is determined that there is no probe car setting (S200: NO), the subsequent processing is not executed and the information transmission processing is terminated.

  In S210, it is determined whether or not idling is in progress. In this process, since it is necessary to evaluate the amount of fuel required under a certain condition, it is determined whether or not the engine is idling. If it is determined that the vehicle is idling (S210: YES), the process proceeds to S220. On the other hand, when it is determined that the engine is not idling (S210: NO), the subsequent process is not executed and the information transmission process is terminated.

  In S220, a fuel injection command amount (hereinafter referred to as “injection command amount” as appropriate) is acquired. In this process, an injection command amount for the gasoline injector 32 is acquired from the gasoline injection ECU 31 of the injection device 30 via the input / output I / F 18.

  In continuing S230, the injection quantity by load is acquired. This process acquires an injection amount that increases due to a vehicle load such as an air conditioner. This injection amount is also acquired from the gasoline injection ECU 31 via the input / output I / F.

  In the next S240, various information is transmitted to the center 20. The various types of information include information on the injection command amount acquired in S220, the injection amount based on the load acquired in S230, the information on the last gas station, oil type, and vehicle type.

  Next, the counting process will be described based on the flowchart of FIG. This aggregation process is executed by the center side control unit 21 of the center 20. This aggregation process is executed when information from the navigation device 10 is transmitted by the information transmission process described above.

  In the first S300, the injection command amount is corrected. This process corrects the injection command amount transmitted in S240 in FIG. Specifically, the injection amount due to the load acquired in S230 is subtracted from the injection command amount acquired in S220 to correct the increase in the injection amount due to the vehicle load such as an air conditioner.

  In subsequent S310, the corrected injection command amount is registered. In this process, the injection command amount at idling is calculated and registered in the database 22 for each vehicle type, each gas station, and each oil type. For example, as shown in FIG. 5, the vehicle type A, the oil type “Regular”, and the injection command amount at the stand a are made into a database such as “a1”.

In the next S320, totalization is performed for the same vehicle type. Specifically, for each vehicle type, the standard deviation and average value of the injection command amount are obtained for each gas station and oil type.
In subsequent S330, totalization is performed for all vehicle types. Based on the standard deviation and average value obtained for each vehicle type in S320, the standard deviation and average value of the injection command amount are obtained for each gas station and oil type in all vehicle types.

Next, the stand search process will be described based on the flowchart of FIG. This stand search process is executed by the control unit 11 of the navigation device 10.
In the first S400, the oil type price is acquired. In this process, the fuel price for each oil type is acquired for the surrounding gas stations. Such fuel price information is assumed to be managed by the center 20 and is obtained by making an inquiry to the center 20.

In continuing S410, fuel consumption statistics information is acquired. In this process, the standard deviation and the average value of the injection command amount for all vehicle types obtained in S330 in FIG. 4 are acquired.
In the next S420, the estimated fuel consumption is calculated. In this process, the estimated fuel consumption is obtained in consideration of the actual fuel consumption of the host vehicle based on the standard deviation and average value of the injection command amount acquired in S410. The estimated fuel efficiency is a value estimated as the fuel efficiency of the host vehicle when using a plurality of fuels classified by the gas station and the oil type.

  In subsequent S430, refueling information is displayed. This process displays the fuel supply information for each stand on the image display unit 16 in FIG. For example, displaying information as shown in FIG. 7 is exemplified.

  In FIG. 7, information for each oil type (Fuel Type) is displayed. In this example, “Regular” is indicated by the symbol A, but “Mid-grade”, “Premium”, and “Diesel” can be selected in addition.

  Further, as indicated by symbol B, the stand name is displayed, and information for each stand is displayed. In the column indicated by the symbol C, the “oil type price” acquired in S400 in FIG. 6 is displayed. The column indicated by the symbol D displays “estimated fuel cost” acquired in consideration of the estimated fuel consumption calculated in S420.

  The “estimated fuel cost” is “a fuel cost (¢ / mi) necessary for traveling a unit distance”. In other words, this is “oil type (fuel) price ($ / gal) × fuel amount necessary to travel a unit distance (gal / mi)”.

  The “fuel amount necessary to travel a unit distance (gal / mi)” in the latter stage of the above equation is the estimated fuel consumption, but the estimated fuel cost is simply displayed by displaying the estimated fuel cost instead of the estimated fuel consumption. The fuel cost required for the user to travel can be shown more clearly. Note that ¢, $, gal, and mi are examples of units to be calculated, and other units may be used.

  Looking at “oil type price”, for example, “stand a” is “3.50” dollars per gallon, and “stand c” is “3.48” dollars per gallon. “Stand c” is the lowest price in terms of oil price.

  On the other hand, regarding “estimated fuel cost”, for example, “stand c” is “14.8” cents per mile, and although the oil type price is low, the estimated fuel cost is considered as a result of considering the estimated fuel consumption. It turns out that is not so good. The estimated fuel cost is improved at “Stand b” and “Stand d”, which is “14.4” cents per mile.

Therefore, it is best from the economical point of view to select “stand b” or “stand d” whose estimated fuel cost is relatively good.
The stand information is sorted and displayed in a predetermined order. As indicated by the symbol E, the sorting is based on the “distance” from the vehicle. In addition, it is possible to preferentially display stands on the route, sort by oil type price, sort by estimated fuel consumption or estimated fuel cost.

  The column of symbol F indicates the direction of the stand from the host vehicle, and the column of symbol G indicates the distance from the host vehicle to the stand. Symbol H is a “return button”, and it is possible to return to the previous screen by touching. Furthermore, the symbol I is a scroll bar, and the search result can be scrolled when the number of searched stands is large.

Next, the effect which the navigation apparatus 10 of this embodiment exhibits is demonstrated.
In the navigation apparatus 10 of the present embodiment, the estimated fuel consumption calculation means 11a acquires fuel consumption statistical information from the center 20 (S410 in FIG. 6), and calculates the estimated fuel consumption of the oil type for each stand based on the actual fuel consumption in the vehicle. (S420). Then, the information providing unit 11b displays the fuel supply information including the estimated fuel consumption calculated by the estimated fuel consumption calculating unit 11a (S430).

  That is, based on the fuel consumption statistical information stored in the center 20, the estimated fuel consumption of the oil type for each stand is calculated, and the fuel supply information including the estimated fuel consumption is provided. In this way, fuel consumption due to different fuel qualities for each stand is taken into consideration, and fuel supply information including an economic viewpoint can be provided.

  Further, in the present embodiment, the fuel injection amount under a certain condition is aggregated and statistically processed at the center 20 (S320 and S330 in FIG. 4). That is, the fuel consumption statistical information is obtained by statistically processing the fuel injection amount under a certain condition of the vehicle. Thereby, a more accurate estimated fuel efficiency can be calculated.

  At this time, the fuel injection amount is acquired from the gasoline injection ECU 31 based on the injection command amount (S220 in FIG. 3). That is, the fuel injection amount is based on the fuel injection command amount from the fuel injection ECU in each vehicle. Although it is difficult to measure the actual value of the fuel injection amount, the fuel injection amount can be appropriately grasped by using the injection command amount of the gasoline injection ECU 31 in this way.

  At this time, the fuel injection amount due to a load such as an air conditioner is acquired (S230 in FIG. 3), and the injection command amount is corrected (S300 in FIG. 4). That is, the fuel injection amount is based on the fuel injection command amount and the load injection amount based on the engine load in each vehicle. Thereby, the estimated fuel consumption can be calculated in consideration of an increase in the fuel injection amount due to a load such as an air conditioner.

  Further, at this time, it is determined whether or not the engine is idling (S210 in FIG. 3), and when the engine is idling, the injection command amount is acquired (S220). That is, the idling is performed under a certain condition. As a result, the fuel injection amount as a sample can be collected relatively easily.

  Furthermore, in this embodiment, the fuel injection amount that is aggregated and statistically processed by the center 20 is acquired by the navigation device 10 and transmitted to the center 20. That is, the fuel supply information providing device includes information transmission means 11c that acquires the fuel injection amount based on the information of the host vehicle and transmits the fuel injection amount to the center. Thereby, information on the fuel injection amount can be collected relatively easily.

  However, in the information transmission process, it is determined whether or not it is set as a probe car (S200 in FIG. 3), and when it is set as a probe car (S200: YES), information is transmitted (S240). That is, the information transmission means transmits the fuel injection amount to the center when the host vehicle is a probe car. Thereby, highly reliable information is collected.

  Specifically, when the oil is supplied from the same stand and the oil type is not changed (S150: YES, S160: NO in FIG. 2), the probe is set as a probe car (S180). That is, the refueling information providing device further includes a refueling determination unit 11d that determines whether or not refueling of the same oil type as the previous time is performed in the same stand as the previous time when refueling is performed. And when it is oil supply of the same oil type in the same stand, let the own vehicle be a probe car. Thereby, highly reliable information is collected.

  Further, even when the fuel is not refueled at the same stand or when the oil type is changed (S150: NO, S160: YES in FIG. 2), if the fuel is sufficient (S170: YES), it is set as a probe car. (S180). That is, the fuel supply information providing apparatus sets the own vehicle as a probe car when sufficient fuel supply is performed even when the same oil type is not supplied in the same stand. Thereby, highly reliable information is collected.

  In the present embodiment, the navigation device 10 also includes price information acquisition means 11e for acquiring the price information for each stand from the outside of the vehicle (for example, the center 20), and the estimated fuel consumption and price information for each stand. And a fuel cost calculation means 11f for calculating an estimated fuel cost, which is a fuel cost required for traveling a unit distance, for each oil type for each stand. The estimated fuel cost is presented as the above-described fuel supply information.

Since the estimated fuel cost is a fuel cost required for traveling a predetermined distance (unit distance) in consideration of the estimated fuel efficiency, the user can acquire fuel supply information including an economical viewpoint.
[Second Embodiment]
Since the navigation system according to the second embodiment is only partially different from the navigation system according to the first embodiment in the processing performed by the control unit 11 of the navigation apparatus 10, only the parts related to the difference will be described and the same. I will omit the explanation of the part.

  The stand search process, which is a characteristic process of the present embodiment, will be described based on the flowchart of FIG. This stand search process is a process executed by the control unit 11 of the navigation apparatus 10 and is repeatedly executed when the route guidance process described above is being executed by the control unit 11.

  In the first S500, it is determined whether or not the residual oil amount has decreased. In this process, the amount of fuel remaining in the fuel tank of the vehicle is acquired, and it is determined that the amount of residual oil is small when the amount is less than a predetermined threshold. If it is determined that the residual oil amount is not small (S500: NO), the process returns to S500 again. That is, it waits until the amount of residual oil becomes small. On the other hand, when it is determined that the amount of residual oil is small (S500: YES), the process proceeds to S510.

  The subsequent process of acquiring the oil type price in S510, the process of acquiring the fuel economy statistical information in S520, and the process of calculating the estimated fuel efficiency in S530 are the same processes as S400, S410, and S420 in FIG.

  In subsequent S540, refueling information is displayed. In this process, the image display unit 16 displays refueling information indicating a station capable of refueling the fuel with the lowest estimated fuel cost among the stations existing along the route to the destination calculated in the route guidance process. To do.

  For example, as shown in FIG. 9, the estimated fuel cost is displayed in order from the top in the order of cheap stations. The symbol J indicates that the stand information displayed in FIG. 9 is a stand along the route. Further, as indicated by the symbol E, it is sorted based on “Cost”, indicating that the display is based on the estimated fuel cost.

  In FIG. 9, among the stands b and d where the estimated fuel cost is the cheapest, the stand b that is closest to the vehicle is displayed and highlighted at the top. The display method in the case where there are a plurality of stations with the cheapest estimated fuel cost is not limited to this. For example, the station displayed at the top may be determined based on the oil type price. Further, both the stand b and the stand d may be highlighted without considering other conditions.

Next, the effect which the navigation apparatus 10 of this embodiment exhibits is demonstrated.
In the navigation apparatus 10 according to the present embodiment, when the residual oil amount determination unit 11g determines that the residual oil amount is equal to or less than a predetermined threshold, the navigation apparatus 10 includes a stand that exists along the route calculated by the route calculation unit 11h. Therefore, the information providing means 11b provides information on a station that can supply fuel with the cheapest estimated fuel cost.

  Therefore, it is possible to present a stand capable of refueling the best fuel from an economical viewpoint, rather than simply comparing the fuel consumption for each oil type and the price per unit amount, among the stands that are easily accessible by the vehicle. Thereby, the user can perform a gas station selection easily and appropriately.

[Other Embodiments]
The present invention is not limited to the embodiment described above, and can be implemented in various forms without departing from the technical scope thereof.

  In each of the above embodiments, as the fuel supply information to be displayed on the image display unit 16, the estimated fuel cost obtained by multiplying the estimated fuel consumption by the oil type price and the oil type price are exemplified, but the estimated fuel consumption itself is displayed. A configuration may be adopted.

  In each of the above embodiments, as shown in FIG. 5, the vehicle type A, the vehicle type B,. On the other hand, you may make it create the database for every vehicle. In this case, although the amount of data increases, it is advantageous in that the accuracy becomes higher.

  The fuel consumption statistical information acquired in S410 of FIG. 6 may be the fuel consumption statistical information for each vehicle type or for each vehicle, instead of the fuel consumption statistical information for all vehicle types. The estimated fuel consumption can be calculated with high accuracy by using the same vehicle type as the host vehicle or the fuel consumption statistical information of the host vehicle itself.

  Moreover, in each said embodiment, although the structure with which the function of the estimation fuel consumption calculation means 11a was provided in the navigation apparatus 10 (fuel supply information provision apparatus) mounted in the vehicle was illustrated, as shown in FIG. The structure provided with the function of the estimated fuel consumption calculation means 11a may be sufficient.

  In such a fuel supply information providing system, for example, the estimated fuel consumption of a general vehicle based on the fuel consumption statistical information of all vehicle types can be calculated by the center 20. The calculated estimated fuel consumption may be displayed as it is on the image display unit 16, or the estimated fuel cost considering the actual fuel consumption of the host vehicle and the oil type price may be displayed. In order to calculate the estimated fuel consumption in consideration of the actual fuel consumption of the vehicle at the center 20, the center 20 may be configured to acquire information on the actual fuel consumption from the navigation device 10.

  In the second embodiment, the refueling information indicating the stations that can be refueled with the cheapest estimated fuel cost is selected from the stations that exist along the route to the destination calculated by the route guidance process. The structure to display was illustrated. However, the information on the stand to be displayed is not limited to information existing along the route, and may be limited by other conditions.

  For example, the information providing unit 11b may provide information on a station that can supply fuel with the cheapest estimated fuel cost among the stations existing within a predetermined distance from the reference point. For example, the reference point may be a point set by a user such as a home. In addition, a point automatically extracted as a point where the vehicle frequently parks may be used as a reference point.

  For example, as shown in FIG. 11, the information displayed at this time is displayed side by side from the top in the order of the stations where the estimated fuel cost is low. As indicated by the symbol J, the stand information displayed in FIG. 11 is a stand around the home. Further, as indicated by the symbol E, it is sorted based on “Cost”, indicating that the display is based on the estimated fuel cost.
