FIG. 4 is an operation flowchart of the vehicle 2. It is a figure which shows the structure of the vehicle 2 which concerns on 2nd Embodiment.

<First Embodiment>
[Configuration of Key 1 and Vehicle 2]
FIG. 1 is a diagram illustrating a configuration of a key 1 and a vehicle 2 according to the first embodiment. The key 1 includes a key storage unit 11 and a key communication unit 12.

  The key storage unit 11 is a non-volatile memory such as a flash memory, and stores a user ID that is identification information of a driver who owns the key 1 and a vehicle ID that is identification information used in communication with the vehicle 2. ing. Further, the key storage unit 11 receives driving tendency information indicating the driving tendency of the driver generated from the past driving information recorded when the driver has driven the vehicle 2 in the past from the vehicle 2. The received driving tendency information is stored.

  When the key communication unit 12 approaches a predetermined distance from the vehicle 2, the key communication unit 12 wirelessly transmits the user ID and the vehicle ID stored in the key storage unit 11 to the vehicle 2. In addition, the key communication unit 12 transmits the driving tendency information stored in the key storage unit 11 to the vehicle 2.

  The vehicle 2 includes a vehicle communication unit 21, a vehicle state acquisition unit 22, a vehicle storage unit 23, an engine 24, a display unit 25, and a driving state monitoring unit 26. The driving state monitoring unit 26 includes, for example, a CPU, and executes a program stored in the vehicle storage unit 23 to obtain an acquisition unit 261, a vehicle control unit 262, a driving state recording unit 263, and a process execution unit 264. Function.

The vehicle communication unit 21 performs wireless communication with the key communication unit 12 and receives a user ID, a vehicle ID, and driving tendency information from the key communication unit 12. In addition, the vehicle communication unit 21 transmits driving tendency information indicating the driving tendency of the driver to the key 1.
The vehicle state acquisition unit 22 includes various sensors that acquire the state of the vehicle 2. The vehicle state acquisition unit 22 detects, for example, the accelerator opening, the deceleration, the distance from the preceding vehicle, and the steering amount of the steering wheel. The vehicle state acquisition unit 22 notifies the driving state monitoring unit 26 of the detected vehicle state.

  The vehicle storage unit 23 includes a ROM (Read Only Memory) and a RAM (Random Access Memory). The vehicle storage unit 23 stores a program executed by the driving state monitoring unit 26. The vehicle storage unit 23 stores a user ID and a vehicle ID that are set in advance. Furthermore, the vehicle storage unit 23 stores information indicating the vehicle state acquired by the vehicle state acquisition unit 22 when the driver corresponding to the user ID has driven the vehicle 2 in the past in association with the user ID.

The engine 24 operates based on the control of the vehicle control unit 262. For example, the engine 24 starts to operate in response to receiving a start instruction from the vehicle control unit 262 and stops operating in response to receiving a stop instruction.
The display unit 25 is a display provided on the instrument panel. The display unit 25 displays information to be presented to the user based on the control of the process execution unit 264. A touch panel may be provided on the surface of the display unit 25. In this case, the display unit 25 functions as an operation unit that receives an operation by the driver.

Hereinafter, the structure of each part of the driving | running state monitoring part 26 is demonstrated.
The acquisition unit 261 acquires a user ID and a vehicle ID as identification information for identifying the driver from the key 1. The acquisition unit 261 acquires the user ID and vehicle ID stored in the vehicle storage unit 23 and compares them with the user ID and vehicle ID received from the key 1. When the user ID and vehicle ID received from the key 1 match the user ID and vehicle ID acquired from the vehicle storage unit 23, the acquisition unit 261 indicates that the driver is a regular driver and The operation state recording unit 263 is notified.

  When the user ID and vehicle ID received from the key 1 match the user ID and vehicle ID acquired from the vehicle storage unit 23, the acquisition unit 261 uses the display unit 25 provided with a touch panel as authentication information. You may receive a password or PIN. The acquisition unit 261 controls the vehicle that the driver is a regular driver when the password input by the user matches the password stored in the vehicle storage unit 23 in advance in association with the user ID. You may notify to the part 262 and the driving | running state recording part 263. FIG. In addition, the acquisition unit 261 acquires the driving tendency information of the driver from the key 1 and notifies the driving state recording unit 263 of it.

  The vehicle control unit 262 controls the operation of the engine 24. The vehicle control unit 262 permits traveling on the condition that the acquisition unit 261 has acquired regular identification information. For example, when the vehicle control unit 262 receives a notification from the acquisition unit 261 that the driver is a regular driver, the vehicle control unit 262 starts the engine 24. In addition, when the vehicle control unit 262 receives an instruction to stop the engine 24 from the processing execution unit 264, the vehicle control unit 262 stops the engine 24.

  When the driving state recording unit 263 receives a notification that the driver is a regular driver, the driving state recording unit 263 subsequently acquires current driving information indicating the driving state from the vehicle state acquisition unit 22 and acquires the user from the acquisition unit 261. The current driving information is stored in the vehicle storage unit 23 in association with the ID. Specifically, the driving state recording unit 263 is generated based on the acceleration at the start, the deceleration at the time of stopping, the distance from the preceding vehicle, and the steering acceleration of the steering wheel acquired from the vehicle state acquisition unit 22 at predetermined intervals. The current driving information is stored in the vehicle storage unit 23.

  The driving state recording unit 263 is based on the acceleration at the start, the deceleration at the time of stopping, the distance from the preceding vehicle, and the steering acceleration of the steering wheel acquired from the vehicle state acquisition unit 22 at predetermined intervals. Quantify the trend of For example, the driving state recording unit 263 classifies the acceleration at the time of starting, the deceleration at the time of stopping, the distance to the preceding vehicle, the magnitude of the steering acceleration of the steering wheel, the average speed, and the like into driving tendencies represented by numerical values in a plurality of stages. And driving tendency information is generated.

  The driving state recording unit 263 stores the current driving information in the vehicle storage unit 23 and also stores the driving tendency information generated based on the current driving information in the key storage unit 11. For example, the driving state recording unit 263 stores the driving tendency information in the key storage unit 11 by transmitting the driving tendency information to the key communication unit 12 via the vehicle communication unit 21. The driving state recording unit 263 may store driving tendency information in the vehicle storage unit 23 or may notify the processing execution unit 264. Further, the driving state recording unit 263 may store the current driving information in the key storage unit 11.

  FIG. 2 is a diagram illustrating an example of driving tendency information stored in the key storage unit 11 by the driving state recording unit 263. In the table of FIG. 2, the acceleration, deceleration, inter-vehicle distance, and steering acceleration indicate any of the five stages. For example, when the driver's start acceleration is very large and the driver tends to start suddenly, the driving state recording unit 263 sets the acceleration tendency to “5” and the start acceleration tends to be very small. In this case, the acceleration tendency is set to “1”. The driving state recording unit 263 sets the deceleration tendency to “5” when the deceleration at the time of stopping is very large and the brakes tend to be applied suddenly, and when the deceleration at the time of stopping tends to be very small. The deceleration tendency is “1”.

  The driving state recording unit 263 sets the inter-vehicle distance tendency to “5” when the inter-vehicle distance tends to be very small, and sets the inter-vehicle distance tendency to “1” when the inter-vehicle distance tends to be very large. The driving state recording unit 263 sets the steering acceleration tendency to “5” when the steering acceleration is very large and tends to turn the steering wheel suddenly, and sets the steering acceleration tendency to “1” when the steering acceleration is very small. And

  The driver whose user ID is 001 shown in the table of FIG. 2 has a relatively large acceleration tendency, deceleration tendency, and steering acceleration tendency, so that it is understood that the driver tends to drive rough. It can be seen that the user with the user ID 003 tends to drive safely because the acceleration tendency and the deceleration tendency are relatively small.

  The process execution unit 264 includes past driving information indicating the past driving state stored in the key storage unit 11 or the vehicle storage unit 23, and current driving information acquired from the vehicle state acquisition unit 22 while the driving state recording unit 263 is driving. Based on the result of the comparison, the processing related to the traveling of the vehicle 2 is executed. The process execution unit 264 causes the vehicle control unit 262 to stop driving when the difference between the current driving information and the past driving information exceeds a predetermined range.

  The process execution unit 264 uses, for example, driving tendency information stored in the key storage unit 11 as past driving information. In this case, the process execution unit 264 acquires the driving tendency information generated by the driving state recording unit 263 based on the current driving information, and the correlation between the acquired driving tendency information and the driving tendency information stored in the key storage unit 11. Calculate the value. When the calculated correlation value is greater than the predetermined first threshold, the process execution unit 264 determines that the driver is driving with a tendency similar to the past driving tendency, and the display unit 25 displays the driving state. To show that is good.

  The process execution unit 264 causes the display unit 25 to display that the driving tendency is different from the normal when the calculated correlation value is equal to or less than the first threshold value. The process execution unit 264 determines that the driver is not a regular driver when the calculated correlation value is equal to or less than a second threshold value that is smaller than the first threshold value, and causes the vehicle control unit 262 to turn the engine 24 on. Instruct to stop. In this case, the processing execution unit 264 may control the vehicle control unit 262 to stop the engine 24 after the vehicle 2 stops because it is dangerous to stop the engine 24 suddenly while the vehicle 2 is traveling. The process execution unit 264 instructs the vehicle control unit 262 to stop the engine 24 and displays a warning on the display unit 25 that the vehicle 2 is stopped because there is a suspicion of theft. A predetermined contact address (for example, the contact address of the owner of the vehicle 2) may be notified via the communication unit 21.

[Operation Flowchart of Vehicle 2]
FIG. 3 is an operation flowchart of the vehicle 2.
First, the acquisition unit 261 acquires identification information (user ID and vehicle ID) and driving tendency information from the key 1 (S11). Subsequently, the acquisition unit 261 displays a screen for inputting a password on the display unit 25 (S12).

  The acquisition unit 261 compares the input password with the password stored in the vehicle storage unit 23 in association with the user ID (S13). If the two do not match (NO in S13), the acquisition unit 261 displays “The engine cannot be started because the password is incorrect” on the display unit 25. If the two match each other (YES in S13), the acquisition unit 261 notifies the vehicle control unit 262 to that effect, and the vehicle control unit 262 starts the engine 24 (S14).

  When the engine 24 is started, the operation state recording unit 263 starts recording the current operation information (S15). While the driving state recording unit 263 records the current driving information, the process execution unit 264 compares the current driving information with the driving tendency information acquired by the acquiring unit 261 (S16). If it is determined that the driving tendency information is not different from the current driving information (NO in S16), the process execution unit 264 returns to S15 and continues recording the current driving information. If it is determined that the driving tendency information is different from the current driving information (YES in S16), the process execution unit 264 instructs the vehicle control unit 262 to stop the engine 24 (S17). In S16 described above, the process execution unit 264 may use past driving information stored in the vehicle storage unit 23 instead of the driving tendency information.

[Modification 1]
In the above description, the vehicle storage unit 23 stores past driving information in association with the user ID, and the key storage unit 11 stores driving tendency information in association with the user ID. Since the driving tendency changes depending on surrounding conditions such as road conditions, weather, and the degree of congestion, the driving condition recording unit 263 associates the past driving information with the vehicle detected by a sensor (not shown). You may memorize | store in the memory | storage part 23. FIG. Moreover, the driving | running state recording part 263 may produce | generate the driving | running tendency information linked | related with the surrounding condition, and memorize | store driving tendency information in the key memory | storage part 11 linked | related with the surrounding situation.

[Modification 2]
In the above description, the case where the key storage unit 11 stores one user ID has been described. However, the key storage unit 11 stores a plurality of user IDs and stores driving tendency information in association with the user IDs. May be. In this case, the vehicle storage unit 23 stores a plurality of passwords in association with a plurality of user IDs. The key 1 transmits a plurality of user IDs to the vehicle 2 in the vicinity of the vehicle 2, and the acquisition unit 261 refers to the vehicle storage unit 23 and specifies a user ID corresponding to the password input by the driver. In this way, the acquisition unit 261 can specify the driver's user ID.

Thereafter, the vehicle communication unit 21 receives the driving tendency information associated with the specified user ID from the key communication unit 12, and the process execution unit 264 executes a process based on the received driving tendency information. When the vehicle 2 starts traveling, the driving state recording unit 263 stores the current driving information in the vehicle storage unit 23 in association with the identified user ID.
In this modification, the key 1 has an operation unit, the driver selects his / her user ID from a plurality of user IDs, and the key 1 transmits the selected user ID to the vehicle 2. It may be a thing.

[Effect in the first embodiment]
As described above, in the vehicle 2 according to the first embodiment, the process execution unit 264 performs the past driving information stored in the vehicle storage unit 23 and the current driving acquired by the driving state recording unit 263 during driving. A process based on the result of comparison with information is executed. For example, when the difference between the current driving information and the past driving information exceeds a predetermined range, the processing execution unit 264 may not be driving the legitimate driver and the vehicle 2 may be stolen. And the traveling of the vehicle 2 is stopped. By doing in this way, when the key 1 is stolen or when a family with dementia is driving the vehicle 2, it is possible to make it difficult for non-regular drivers to continue driving.

  The driving state recording unit 263 stores the current driving information in the vehicle storage unit 23 and also stores the driving tendency information specified based on the current driving information in the key storage unit 11. Since the data amount of the driving tendency information is smaller than the data amount of the current driving information, the driving tendency information can be transmitted from the vehicle 2 to the key 1 in a short time, and the capacity of the key storage unit 11 can be reduced.

  The key storage unit 11 stores a plurality of user IDs, and the driving state recording unit 263 associates the current driving information with the user ID corresponding to the driving driver among the plurality of user IDs. The driving tendency information is stored in the key storage unit 11 in association with the user ID. By doing in this way, even if it is a case where a plurality of drivers share vehicle 2, vehicle 2 can perform operation based on a driver's driving tendency.

<Second Embodiment>
In the first embodiment, when the driving tendency information received from the key communication unit 12 does not match the driving tendency information associated with the user ID stored in the vehicle storage unit 23, the process execution unit 264 causes the engine 24 to The vehicle control unit 262 was controlled to stop the operation. On the other hand, in the second embodiment, the vehicle 2 is connected to an electronic device such as a driver's mobile terminal via a network, and the vehicle 2 is allowed to travel based on the driver's instruction. Different from the first embodiment.

  FIG. 4 is a diagram illustrating a configuration of the vehicle 2 according to the second embodiment. The vehicle 2 shown in FIG. 4 is different from the vehicle 2 of the first embodiment shown in FIG. 1 in that it further includes an external communication unit 27, and is the same in other points. If the process execution unit 264 determines that the past driving information is different from the current driving information, the processing execution unit 264 is configured to contact a preset contact address (for example, contact of the mobile terminal of the authorized driver via the external communication unit 27). A message to the effect that it may have been stolen.

  A message confirming whether or not to stop traveling of the vehicle 2 is displayed on the mobile terminal of the legitimate driver. When the authorized driver performs an operation for stopping the traveling of the vehicle 2, a message including an instruction to stop the traveling is transmitted from the portable terminal to the vehicle 2, and the external communication unit 27 receives the message. The external communication unit 27 notifies the received message to the process execution unit 264, and the process execution unit 264 controls the vehicle control unit 262 based on the received notification to stop the engine 24. At this time, the process execution unit 264 may control the vehicle control unit 262 to stop the engine 24 at the timing when the vehicle 2 stops.

  Note that the destination to which the external communication unit 27 transmits a message is not limited to the mobile terminal of a regular driver. For example, the external communication unit 27 may transmit a message to a terminal of a regular driver's family. The external communication unit 27 sends a message to a person other than the driver, so that the driver is in a bad condition, and thus reports that the driver is in an abnormal state when driving different from the past driving tendency. be able to.

[Effects of Second Embodiment]
As described above, in the second embodiment, the vehicle 2 can be stopped by control from an external electronic device connected via a network. By doing so, the vehicle 2 stops traveling when the current driving state is different from the past driving state even though the regular driver is driving the vehicle 2. Can be prevented.

<Third Embodiment>
In the first embodiment, the vehicle 2 uses the driving tendency information associated with the user ID to stop the vehicle 2 at the time of theft. On the other hand, the third embodiment is different in that the vehicle 2 uses the driving tendency information associated with the user ID in order to support the driving of the regular driver.

  The process execution unit 264 causes the vehicle control unit 262 to perform automatic driving based on the driving tendency information received from the key 1. Specifically, the process execution unit 264 indicates that the driving tendency indicated by the driving tendency information received from the key 1 matches the tendency indicated by the past driving information stored in the vehicle storage unit 23 in association with the user ID. In addition, when the driver sets the ACC (Adaptive Cruise Control, travel / inter-vehicle distance control device) mode, the vehicle control unit 262 is automatically driven based on the inter-vehicle distance and speed indicated by the driving tendency information. The process execution unit 264 may adjust the strength of the brake based on the deceleration indicated by the driving tendency information when operating the AEB (Autonomous Emergency Braking). Further, the process execution unit 264 may adjust the steering wheel operation amount based on the steering amount indicated by the driving tendency information when operating the LKAS (Lane Keep Assistant System).

[Effect in the third embodiment]
As described above, in the third embodiment, the vehicle 2 can automatically drive based on the driving tendency information. By doing in this way, the driver can maintain the traveling state according to his / her preference even during the automatic driving.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be added to the above embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention. For example, in the above description, the example in which the vehicle 2 acquires the user ID and password from the key 1 has been described, but the vehicle 2 does not use the user ID and password, and the vehicle ID acquired from the key 1 matches. Alternatively, the engine 24 may be started.

  In the above description, the past driving information is stored in the vehicle storage unit 23, and the driving tendency information generated based on the past driving information is stored in the key storage unit 11. However, the present invention is not limited to this. The vehicle storage unit 23 may not store past driving information, and the key storage unit 11 may store past driving information. In this case, after the key 1 transmits the user ID and the vehicle ID to the vehicle 2, the key 1 transmits past driving information to the vehicle 2, and the vehicle 2 stores the received past driving information in the vehicle storage unit 23.

  Further, the vehicle 2 may store the past driving information in association with the information indicating the vehicle type and the user ID in an external server without storing the past driving information in the vehicle storage unit 23. In this case, after the key 1 transmits the user ID and the vehicle ID to the vehicle 2, the past driving information when the vehicle 2 having the same user ID is driven in the past is acquired from an external server. By doing in this way, when the driver drives a plurality of vehicles 2 of the same type, it is possible to refer to past driving information when driving other vehicles 2, so even in the vehicle 2 that gets on for the first time The effect produced in the above embodiment can be obtained.
