The GPS unit 110 detects radio waves transmitted from a plurality of satellite communications (not shown), and acquires position information of the vehicles 1a and 1b (hereinafter collectively referred to as “vehicle 1”). The vehicle position information acquired by the GPS unit 110 is transmitted to the control device 170.
The vehicle speed sensor 120 detects the vehicle speed of the vehicle 1. The vehicle speed information of the vehicle 1 detected by the vehicle speed sensor 120 is transmitted to the control device 170.

The shift position sensor 130 detects the shift position of the vehicle 1. The vehicle shift position information detected by the shift position sensor 130 is transmitted to the control device 170.
The steering angle sensor 140 detects the steering angle of the vehicle 1. The steering angle information of the vehicle 1 detected by the steering angle sensor 140 is transmitted to the control device 170.
In addition to storing map data, the map information database 150 stores road information such as road link information of each road, and is read out and used by the control device 170 as needed.

  The vehicle travel history database 160 stores vehicle travel history information that is data related to the travel history of the vehicle 1. In the present embodiment, the information regarding the vehicle position, the vehicle speed, the shift position, and the steering angle acquired from the GPS unit 110, the vehicle speed sensor 120, the shift position sensor 130, and the steering angle sensor 140 by the control device 170 is the vehicle traveling. It is recorded in the vehicle travel history database 160 as history information. Further, the vehicle travel history information stored in the vehicle travel history database 160 is read and used by the control device 170 as needed.

The map information database 150 and the vehicle travel history database 160 are databases stored in a storage area such as a RAM or a ROM (not shown) provided inside or outside the parking lot information collection device 100.
The control device 170 includes a ROM (Read Only Memory) 171 that stores a program for executing parking lot information collection processing according to the present embodiment, and a CPU (Central Processing Unit) 172 that executes a program stored in the ROM 171. And a RAM (Random Access Memory) 173 that functions as an accessible storage device. As an operation circuit, an MPU (Micro Processing Unit), a DSP (Digital Signal Processor), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or the like is used instead of or in addition to the CPU 172. it can.

The in-vehicle device communication device 180 communicates with the server device 300 of the data center 2 installed outside the vehicle, and exchanges information with the server device 300.
FIG. 3 is a functional block diagram illustrating an example of the configuration of the parking lot information collection device 100. The control device 170 in FIG. 2 executes the program stored in the ROM 171 by the CPU 172, thereby realizing the processing in each configuration shown in FIG.

Hereinafter, each configuration shown in FIG. 3 will be described. In the following description, description will be made using the configuration shown in FIG. 2 as appropriate.
As illustrated in FIG. 3, the parking lot information collection device 100 according to the present embodiment includes a processing start determination unit 101, a parking completion determination unit 102, a vehicle travel history information acquisition unit 103, a road determination unit 104, and a parking start time calculation. Unit 105, parking ease calculation unit 106, driving skill determination unit 107, and parking lot information transmission unit 108.

  The process start determination unit 101 determines whether to start the parking information collection process. Specifically, the parking completion determination unit 102 determines that the parking is completed during the previous parking lot information collection process, and is set in advance between the vehicle position of the vehicle 1 and the current vehicle position during the previous process. If there is no difference more than the distance (for example, 10 m or more), it is determined that the parking lot information collection process is not started, and otherwise, it is determined that the parking lot information collection process is started.

  In addition, in order to determine that “the parking completion determination unit 102 determines that the parking is completed during the previous parking lot information collection process”, for example, a parking completion flag is provided, and the parking completion determination unit 102 determines that the parking is complete. In this case, the parking completion flag is set to “1”, and when the processing start determination unit 101 determines that the processing is started, the parking completion flag may be set to “0”.

With such a mechanism, when parking of the vehicle 1 is completed, the parking lot information can be generated only once and transmitted to the server device 300 of the data center 2. In addition, the parking lot information collecting apparatus 100 does not perform useless processing and can suppress the processing amount.
The parking completion determination unit 102 determines whether the vehicle 1 has been parked. Specifically, the determination is made based on the shift position information acquired by the shift position sensor 130. For example, when the shift position is a parking shift, it can be determined that parking has been completed.

  In addition, after it determines with the process start determination part 101 starting the collection process of parking lot information, until it determines with the parking completion determination part 102 having completed the parking of the vehicle 1, the vehicle travel history information acquisition part mentioned later At 103, the vehicle travel history information collection process is repeatedly executed. In addition, when the parking completion determination unit 102 determines that the parking of the vehicle 1 has been completed, a parking ease calculation unit 106 (to be described later) performs a parking ease calculation process.

  The vehicle travel history information acquisition unit 103 acquires vehicle travel history information including position information of the vehicle 1, travel speed, and travel time information. In the present embodiment, the position information of the vehicle 1 is acquired by the GPS unit 110. Further, the traveling speed of the vehicle 1 is acquired by the vehicle speed sensor 120. The acquired position information, travel speed, and travel time information of the vehicle 1 are recorded and retained in the vehicle travel history database 160 as vehicle travel history information.

In the present embodiment, the vehicle travel history information acquisition unit 103 further acquires the shift position and the steering angle of the vehicle 1 as the vehicle travel history information. The shift position and the steering angle are acquired from the shift position sensor 130 and the steering angle sensor 140, respectively, and are recorded in the vehicle travel history database 160 as vehicle travel history information together with position information, travel speed, and travel time information.
The vehicle travel history information acquisition process is repeatedly executed until the parking completion determination unit 102 determines that the vehicle 1 has been parked.

  The road determination unit 104 determines whether the position of the vehicle 1 is on the road or outside the road. This is because, in order to calculate the parking start time in the parking start time calculation unit 105, which will be described later, the vehicle 1 is located within the parking lot site depending on whether the vehicle 1 is on the road or outside the road. It is because it is judged whether it entered. Specifically, the road determination unit 104 collates the position of the vehicle 1 specified from the map information database 150 and the parking start time calculation unit 105, for example, so that the specified position is on the road or outside the road. It is determined whether.

  When the parking completion determination unit 102 determines that the parking of the vehicle 1 is completed, the parking start time calculation unit 105 performs parking based on the vehicle travel history information before completion of parking acquired from the vehicle travel history database 160. Calculate the start time. The calculated parking start time is used when calculating the parking ease in the parking ease calculating unit 106 as described later.

Specifically, the calculation of the parking start time is executed as follows. That is, the position information of the vehicle 1 in the vehicle travel history information is sequentially input to the road determination unit 104 retroactively from the parking completion determination time, and the position of the vehicle 1 in the road determination unit 104 is “outside road” (that is, parking). The time at which the determination on the road) changes from the determination in the parking lot site) to the determination “on the road” is calculated as the parking start time.
In addition, the parking ease calculation unit 106 of the present embodiment calculates the parking ease using the calculated parking start time as the parking start time when the position of the vehicle 1 enters the parking lot. Thereby, it is possible to more accurately calculate the time required for the completion of parking after entering the parking lot.

  In addition, the parking start time calculation unit 105 sets the parking start time as the parking start time when the vehicle enters a position (for example, within 100 m) away from the position of the vehicle 1 at the time of parking completion determination by a preset distance. Good. That is, in this case, the parking ease calculation unit 106 is a vehicle from the time when the vehicle enters a position (for example, within 100 m) away from the position of the vehicle 1 at the time of parking completion determination to a parking completion time. The parking ease is calculated based on the travel history. Thereby, it is possible to grasp the time from the arrival in the vicinity of the parking lot to the completion of parking. When the vehicle is actually parked in the parking lot, it may be desired to grasp the ease of parking including the surrounding situation such as the ease of reaching the parking lot. In such a case, the parking ease can be calculated more accurately.

  The parking ease calculation unit 106 calculates a parking ease indicating the ease of parking in the parking lot based on the vehicle travel history information. In the present embodiment, the parking ease calculation unit 106 calculates the parking time from the parking start time to the parking completion time of the vehicle 1 and the number of times the vehicle 1 is turned back from the parking start time to the parking completion time obtained from the shift position. Calculated as the ease of parking.

More specifically, the parking ease calculation unit 106 calculates the difference between the parking start time calculated by the parking start time calculation unit 105 and the parking completion time (time at the time of parking completion determination) as the parking completion time. The parking ease calculation unit 106 repeats the reverse shift and the forward shift from the parking start time to the parking completion time from the shift position history stored as the vehicle travel history information in the vehicle travel history information acquisition unit 103. The number of times is calculated as the number of times of reversal.
The parking ease calculation unit 106 determines the final parking ease from the calculated parking completion time and the number of turnovers. For example, both of these may be output as the parking ease, or these may be used. The final parking ease may be calculated by a predetermined calculation formula.

  The driving skill determination unit 107 determines the driving skill of the driver of the vehicle 1. Specifically, for example, based on the vehicle travel history information such as travel speed, shift position, and steering angle recorded in the vehicle travel history database 160, the driving skill of the driver is divided into three stages: expert, normal, and beginner. Judge separately. For example, when the average value of the traveling speed is equal to or less than a preset value, it is determined that the vehicle is a beginner. In addition, for example, a method of calculating the number of turn-backs in the parking action from the recorded shift position, and determining that the driving skill is higher for a driver with a smaller number of turn-backs based on the number of turn-backs is conceivable.

Regarding the determination of the driving skill, a method in which the driver registers in advance in the parking lot information collecting apparatus 100 and determines the driving skill by self-reporting may be used.
When it is determined that the vehicle 1 is parked in the parking lot, the parking lot information transmission unit 108 can easily park the parking lot where the vehicle 1 is parked, and the parking lot identification information for identifying the parking lot where the vehicle 1 is parked. The operation information including the degree is transmitted in association with the server device 300.

  In addition, the parking lot identification information for specifying the parking lot may be anything that can uniquely identify the parking lot. For example, it may be parking lot position information (for example, a parking lot position obtained from the GPS unit 110 when parking is completed), or a parking lot ID given in advance to the parking lot. In this embodiment, the parking lot identification information is assumed to be parking lot position information obtained from the GPS unit 110.

Further, in the present embodiment, the parking lot information transmission unit 108 transmits the driving skill determined by the driving skill determination unit 107 in association with the parking lot identification information and the parking ease (driving information). Thereby, when a driver searches for a parking lot, the server apparatus 300 can provide parking lot information according to the driving skill of the driver.
Further, the parking lot information transmission unit 108 may transmit the day of the week on which the vehicle 1 traveled in association with the parking lot identification information and the parking ease (driving information). Thereby, when a driver searches a parking lot, the server apparatus 300 can provide the parking lot information according to the scheduled parking day of a parking plan.

Further, in addition to the above information, the parking lot information transmission unit 108 also transmits information such as a vehicle ID for identifying the vehicle 1 and a parking completion time (or current time) to the server device 300. Also good.
Moreover, transmission of parking lot information etc. is specifically transmitted to the server apparatus 300 via the vehicle equipment communication apparatus 180. FIG. At this time, information such as parking lot identification information (position information), driver's driving skill, running day of the week, parking ease, and the like may be associated with each other by assigning a common identifier, etc., and is always transmitted to the server apparatus 300 at the same time. It does not have to be done.

Specifically, the parking completion determination unit 102 determines that the parking is completed during the previous parking lot information collection process, and is set in advance between the vehicle position of the vehicle 1 and the current vehicle position during the previous process. If there is no difference more than the distance (for example, 10 m or more), it is determined that the parking lot information collection process is not started (step S101 = No), and the process is ended (END). In other cases, it is determined to start the parking lot information collection process (step S101 = Yes), and the process proceeds to step S102.

  In step S102, the parking completion determination unit 102 determines whether the vehicle 1 has been parked. Specifically, when the shift position information acquired by the shift position sensor 130 is a parking shift, it is determined that the parking is completed (step S102 = YES), and the process proceeds to step S104. Otherwise, it is determined that parking has not been completed (step S102 = NO), and the vehicle travel history information acquisition unit 103 obtains the position information, travel speed, travel time information, shift position, and steering angle of the vehicle 1. The vehicle travel history information is acquired and recorded in the vehicle travel history database 160 (step S103), and the process ends (END).

  On the other hand, in step S <b> 104, the parking ease calculation unit 106 calculates the parking ease based on the vehicle travel history information before completion of parking acquired from the vehicle travel history database 160. Specifically, the parking completion time from the start of parking to the end of parking and the number of turnovers (driving information) between them are calculated. Also, as the ease of parking, the time from the time when the vehicle enters a position separated by a preset distance from the parking position at the time of parking completion (for example, within 100 m) to the parking completion time, or during this time Alternatively, the number of times the reverse shift and the forward shift are repeated may be calculated as the number of times of reversal.

Next, the driving skill determination unit 107 determines the driving skill of the driver (step S105). The driving skill is determined in three stages, for example, expert, normal, and beginner.
Finally, the parking lot information transmitting unit 108 includes the vehicle ID, the parking time / day of the week, the parking position obtained from the GPS unit 110, the parking ease (driving information) calculated by the parking ease calculating unit 106 in step S104, and the step. The driving skill information of the driver determined by the driving skill determination unit 107 in S105 is transmitted to the server device 300 via the in-vehicle device communication device 180 (step S106).

The data center communication device 340 receives parking lot information transmitted from the vehicle 1 and other vehicles (not shown). Further, it receives the acquisition request information (search condition) for the parking lot information transmitted from the vehicle 1, and returns the parking lot information (search result) corresponding to the acquisition request to the vehicle 1.
FIG. 9 is a functional block diagram illustrating an example of the configuration of the server device 300. The control device 330 in FIG. 8 executes the program stored in the ROM 331 by the CPU 332, thereby realizing the processing in each configuration shown in FIG.

Hereinafter, each configuration shown in FIG. 9 will be described. In the following description, description will be made using the configuration shown in FIG. 8 as appropriate.
As illustrated in FIG. 9, the server device 300 according to the present embodiment includes an in-vehicle device information reception determination unit 301, a parking lot ID search unit 302, a parking lot information recording unit 303, a parking lot information search unit 304, and average parking easy. A degree calculation unit 305 and a parking lot related information output unit 306 are included.

  The in-vehicle device information reception determination unit 301 receives parking lot information (such as parking lot position information and parking ease (driving information)) transmitted from the parking lot information transmission unit 108 of the parking lot information collection device 100, or parking lot related information. The search condition of the parking lot information transmitted from the search condition transmission unit 201 of the presentation device 200 is received. In addition, before the vehicle 1 transmits the parking lot information or the search condition to the server apparatus 300, the vehicle 1 transmits information indicating which data is to be transmitted to the server apparatus 300 in advance. The determination unit 301 receives this information, and based on the content, whether the data transmitted thereafter is parking lot information or the parking information search condition (parking information acquisition request information). It is determined whether.

  In addition, whether the data is the parking lot information or the search condition in the parking lot information transmitted from the parking lot information collection device 100 or the header portion of the search condition transmitted from the parking lot related information presentation device 200. May be stored. And the vehicle equipment information reception determination part 301 determines whether the transmitted data is parking lot information or the search condition of parking lot information by analyzing the header part etc. of the received data. It may be like this.

  Based on the determination by the in-vehicle device information reception determination unit 301, what kind of processing is performed on the received data is determined. When the transmitted information is parking lot information, the parking lot information recording unit 303 described later records parking lot information. On the other hand, when the transmitted information is a search condition for parking lot information, a parking lot information search unit 304 described later searches for parking lot information.

The parking lot ID search unit 302 is expressed in latitude / longitude when the parking lot information recording unit 303 (to be described later) records parking lot information or when the parking lot information search unit 304 searches for parking lot information. The parking lot ID corresponding to the position information is obtained by searching the parking lot section database 320.
However, the parking lot position information included in the parking lot information and the planned parking position included in the search condition are converted into parking lot IDs in advance in the parking lot information collection device 100 and the parking lot related information presentation device 200. May be output to the server apparatus 300. In this case, the process in the parking lot ID search unit 302 is omitted. As a result, the processing load on the server device 300 is reduced.

The parking lot information recording unit 303 records the parking lot information transmitted from the vehicle 1 in the parking lot information database 310. As the parking lot information, information such as the parking lot ID searched by the parking lot ID search unit 302 from the transmitted parking lot position information, the parking ease (driving information), the driving skill of the driver, the vehicle ID, the parking date / time, the day of the week, etc. Is included.
The parking lot information search unit 304 searches the parking lot information database 310 and extracts parking lot information that matches the search conditions received by the in-vehicle device information reception determination unit 301. The search conditions for this search include the parking lot ID output by the parking lot ID search unit 302 based on the location information of the parking place under consideration for parking, the day and time when parking is scheduled, This includes driver driving skill information.

  For example, it is assumed that search conditions such as “parking lot ID = 10101, scheduled parking day = Monday, scheduled parking time = 13: 00, driver's driving skill = beginner” are given. In this case, the parking lot information search unit 304 has the same parking lot ID, parking day of the week, and driver driving skills from the parking lot information database 310, and a time in which a difference from the scheduled parking time of the search condition is set in advance. The parking lot information of the parking time that is within (for example, 12:30 to 13:30 which is within 30 minutes) is extracted.

  Moreover, multiple parking lot IDs may be sufficient. For example, when a plurality of parking lot IDs existing within a preset distance from the planned parking location are output in the parking lot ID search unit 302, the parking lot information search unit 304 performs a search process with a plurality of parking lot IDs. It may be executed. Thereby, it is possible to provide information on the parking lot close to the planned parking position while widening the driver's choice of the parking lot.

  The average parking ease calculation unit 305 calculates the average value of the parking ease included in the parking lot information extracted by the parking lot information search unit 304. Specifically, parking in each parking lot is performed by dividing the parking ease of the parking lot information extracted by the parking lot information search unit 304 (parking completion time, parking turn-back count) by the number of extracted parking lot information. The average value of the completion time and the average value of the number of parking turnbacks are calculated.

  The parking lot related information output unit 306 outputs the search result in the parking lot information search unit 304. In the present embodiment, the parking lot related information output unit 306, via the data center communication device 340, calculates the average parking completion time and the average number of parking turn-back times (parking number) that are the calculation results of the average parking ease calculation unit 305. (Easiness information), the number of search results, the parking lot ID (or parking lot name, etc.) and the like are output to the vehicle 1 that has transmitted the acquisition request information of the parking lot information.

Determine if it is sent. If it is determined that the parking lot information is transmitted, the process proceeds to step S302 (step S301 = NO), and if it is determined that the parking information search condition is transmitted, the process proceeds to step S303. (Step S301 = YES). Moreover, after this determination, the vehicle equipment information reception determination unit 301 performs a process of receiving parking lot information or search conditions.

When the parking lot information is received, the parking lot information recording unit 303 records the parking lot information transmitted from the vehicle 1 in the parking lot information database 310 in step S302.
On the other hand, when the search condition is received, in step S303, the parking lot information search unit 304 searches the parking lot information database 310 and extracts the parking lot information that matches the search condition of the parking lot information. Then, the average parking ease calculation unit 305 calculates an average parking completion time and an average number of parking turn-back times (parking ease information) using the search result extracted in step S303 (step S304).
Finally, the parking lot related information output unit 306 transmits the calculation result (parking ease information) in step S304 to the vehicle 1 as a search result via the data center communication device 340 (step S305).
