Description

The present invention relates to a technique for locking a vehicle that does not require an engine key for door locking so that the engine cannot be started if a predetermined condition is met in the event that the vehicle forgets to lock the door.

Car sharing systems, in which multiple users share multiple vehicles, are becoming popular. Users who use car sharing complete car sharing membership registration, go to the parking lot where cars for car sharing are secured, and use the car directly (users of car sharing services are not a general public, but a specific ). We utilize a reservation system in which you inform us of the time and time you plan to use in advance using your mobile phone or personal computer.

In order to make car sharing a viable business, the engine key used to drive the vehicle used for car sharing (shared car) must be kept inside the vehicle, and the doors can be unlocked and locked using ultra-short-range wireless communication (contactless communication). In many cases, IC chips (membership cards and smartphones) are used for personal authentication that enable communication.

Patent Document 1 discloses a technique in which a key box is fixed to a vehicle in order to store a driving key for driving the vehicle in an internal storage space (key holder) and manage the lock. This technology uses an IC chip to open and close the vehicle's doors, and once the driver gets in the vehicle, the driver's key is retrieved from a lock box with an electronic key that can be opened and closed using the IC card (see Figure 8). .

On the other hand, as a technique for controlling various locking devices of a vehicle, there are, for example, the following techniques. In other words, by wireless communication between the mobile device (smartphone or membership card) owned by the user of the vehicle and the equipment installed in the vehicle, it is possible to confirm the presence of people around the vehicle and to confirm that the vehicle is being used properly. Electronic key systems exist that automatically unlock a door locking device when a person is approaching the vehicle.

An electronic key system combines techniques for locking and unlocking a vehicle on the condition that information for identifying the individual user of the vehicle is obtained. However, if information to identify individuals is to be left in the vehicle, information security measures must be strengthened. Therefore, a technique such as that disclosed in Patent Document 2 is also provided.

In the technology disclosed in Patent Document 2, the user of the mechanical key is determined from the shape formed on the uneven portion of the mechanical key, and the settings and lock/unlock state of the vehicle corresponding to the user are both controlled. . Therefore, there is a feature that the setting state of the equipment can be easily set according to the user's preference while appropriately managing the locking.

Patent No. 5639411 Japanese Patent Application Publication No. 2015-63827

In car sharing services, there is a desire to omit the engine key by integrating the personal authentication IC chip (membership card or smartphone) used to open and close the door lock. This is because there is a certain degree of convenience for the user, and for the service provider, management can be simplified by integrating the member's IC card and the driving key.

However, if vehicles (hereinafter abbreviated as "keyless shared cars") that integrate the on/off of the engine and the opening/closing of the vehicle's door locks with a personal authentication IC chip become popular, the following problems will arise. is assumed.
That is, if the user forgets to lock the door and leaves the vehicle, a third party who is not the user can get into the vehicle. If a third party who has entered the vehicle has malicious intent, he or she may insert a screwdriver into the keyhole, connect power directly to the cell wiring, start the engine of the vehicle, and drive away (stealing the vehicle). It is possible.

Furthermore, assuming that keyless shared cars become widespread, the following problems are expected. In other words, the shared cars used in car sharing services will not be replaced all at once by keyless shared cars, but will instead be replaced by vehicles that use personal authentication IC chips and engine keys managed inside the car (hereinafter referred to as ``key share cars''). There will be a mixture of keyless and shared cars. If this is the case, users who have used key-shared cars and are using keyless shared cars for the first time are likely to be confused about the operation of starting the vehicle's engine.

Technologies called "smart entry,""intelligent key system," and "keyless start system" are becoming popular, especially in luxury passenger cars. These technologies open and close doors and start the engine without any action from the driver by communicating between a portable device (key, card type key, etc.) worn by the driver and the vehicle's onboard device. be.
However, these related technologies solve problems specific to vehicles used in vehicle sharing services (such as the confusion caused by the coexistence of keyless shared cars and non-keyless shared carts, assuming that a specific number of users will be driving them). This is considered difficult.

Although the explanation has been given using a car sharing service as an example, a similar situation can be assumed in a rental car service in which a specific number of users use many types of cars.

The problem to be solved by the present invention is to prevent vehicle theft without impairing the usability of car sharing or rental car services as much as possible when keyless shared cars become widespread. The goal is to provide technology.

(First invention)
The first invention is a keyless shared car, which is a vehicle in which the on/off of the vehicle engine and the opening/closing of the vehicle door lock are integrated under the control of a personal authentication IC chip. This relates to an engine control device that makes it impossible to start the engine of the keyless shared car if the lock is forgotten.
The engine control device includes an engine sensor that detects whether the engine is turned on or off, and a vehicle lock/unlock sensor that detects unlocking and locking of the door lock of the keyless shared car using the personal authentication IC chip. A driver's door opening/closing sensor that detects the opening/closing of the driver's door in the keyless shared car, a timer that starts measuring time upon receiving a predetermined signal, and a controller that controls whether or not the engine can be started. The vehicle is equipped with an on-vehicle device that performs the following operations .
The timer starts measuring a predetermined time when the engine can be started by detecting a signal indicating that the vehicle is unlocked by the vehicle lock/unlock sensor , and starts measuring a predetermined time by detecting a signal indicating that the vehicle is unlocked by the vehicle lock/unlock sensor. The measurement of the predetermined time is reset by detecting a signal indicating that the driver's door is closed, and the predetermined time is reset when the driver's door open/close sensor detects a signal indicating that the driver's door is not closed. Continue measuring time.
The on-vehicle device detects that the engine has stopped using the engine sensor, and also disables the engine from starting if a predetermined period of time has elapsed since the start of continuous measurement using the timer. (See Figure 2).

(Glossary)
"Share car" refers to a vehicle used for car sharing services and rental car services. The term ``vehicle sharing service'' refers to both a service that manages and operates car sharing and a car rental service.
In the case of car sharing, a person who wishes to use a shared car is generally a member user who has registered as a member in advance.
The "predetermined time" is, for example, 3 minutes or 5 minutes. It can be changed depending on the operation, or a different time can be set for each keyless/shared car.

(effect)
In vehicle sharing services, keyless shared cars are used, which are vehicles in which the on/off of the vehicle engine and the opening and closing of vehicle doors are controlled by a personal authentication IC chip. If the user of the keyless shared car does not close the driver's door and the engine is stopped, the engine of the keyless shared car cannot be started. This prevents vehicle theft.
That is, when the vehicle unlock sensor detects unlocking, the engine can be started. At that time, the timer starts measuring a predetermined time. Thereafter, the driver's door opening/closing sensor detects the opening/closing of the driver's door in the keyless shared car. When the driver's door is closed, the measurement of the predetermined time is reset. If it is detected that the driver's door is not closed, the timer continues to measure the predetermined time. Then, when the engine sensor detects that the engine has stopped and a predetermined time has elapsed since the start of measurement, the engine is disabled from starting.

When it is determined that the user is seated, the timer is controlled to be reset (see FIG. 7).

(effect)
If the driver's door is closed but the driver is not in the driver's seat, the timer will not reset. Therefore, for example, if the driver (person planning to drive) leaves the keyless shared car while it is unlocked with an IC card, the engine will not be able to start. By doing so, the theft of keyless shared cars can be prevented.

(Variation 4 of the first invention)
The first invention is more preferably formed as follows.
That is, when the vehicle management server grasps the current location of the keyless shared car and the current location is near the return location, the vehicle-mounted device displays the return button from the vehicle management server. receive the command,

FIG. 2 is a schematic diagram of the hardware configuration of the first embodiment. It is a flowchart showing an outline of the first embodiment. It is a flow chart showing an outline of a second embodiment. FIG. 3 is a schematic diagram illustrating how operation guidance is provided to member users. It is a schematic diagram showing a case where a member user is loading and unloading luggage. It is a flowchart which shows the issuance procedure of the electronic coupon in 2nd embodiment. It is a flow chart showing an outline of a third embodiment. FIG. 1 is a conceptual diagram showing a prior art.

The present invention will be described below based on embodiments. The drawings used here are FIGS. 1 to 6.
In the following embodiments, a car sharing service will be mainly described. However, car sharing services can be replaced with rental car services.
Hereinafter, the car used for the car sharing service (service target vehicle) may be referred to as a "shared car".
Note that the design etc. of the output display to the multifunctional car navigation device shown in FIG. 6 may be changed as appropriate.

To use the car sharing described in this embodiment, for management and operational reasons, it is first necessary to register as a member. In other words, all "persons who wish to use a vehicle" and "users" who can receive the services shown in the embodiments below have completed membership registration.

When registering as a member, member data such as name, address, and account for payment of usage fees are registered in advance. The registration data is stored in a member database, and a personal authentication IC chip (ID card) for authenticating membership is issued. This ID card is an IC card with the data necessary to authenticate that the user is a member stored in an IC chip, and it can be held over a card reader (vehicle unlock sensor) installed in the shared car. The data can now be read. A locked shared car can also be unlocked using the registered card.

As the personal authentication IC chip, a smartphone can also be used instead of the above-mentioned IC card. That is, predetermined data is loaded into a smartphone of a member user who is capable of contactless communication, and is used as a substitute for an IC card. In the following description, an IC card will be used, so a description of the case where a smartphone is used as an IC chip for personal authentication will be omitted.

(Figure 1)
FIG. 1 shows the relationship between a vehicle management server and a data processing device installed in a service target vehicle (shared car). There is also communication between the mobile communication terminal (mobile phone including smartphone, tablet PC, etc.) associated with the member using the shared car and the vehicle management server, such as reservation confirmation when making a reservation, etc. Communication such as letting you know if you forget something is also possible.

Vehicles eligible for the service include an on-board device that performs wireless communication with the vehicle management server, a vehicle unlock sensor that functions as a card reader, and information such as car navigation as well as various information related to car sharing and messages from member users. A multi-function car navigation device that outputs data is installed as a data processing device.

As described above, the vehicle management server manages members' usage status, reservations, etc., and performs vehicle management of service target vehicles.
In addition to wireless communication with the vehicle management server, the on-vehicle device performs serial communication with the vehicle unlock sensor and multi-function car navigation device.

The multifunctional car navigation device is equipped with a touch panel, and can display messages to member users using various data sent through the in-vehicle device, and can accept input from the member's intention using the touch panel (service button (display) and send the input contents to the on-vehicle device.
To ensure car navigation functionality, current location data is obtained using GPS (Global Position System). The current position data is then transmitted to the vehicle management server via the on-vehicle device.

A dedicated application is installed in advance on the mobile communication terminal of a member who uses a shared car so that it can communicate wirelessly with the vehicle management server. The application is used for things like reserving shared cars.
However, it is not necessary to require a dedicated application, and it may be possible to receive communications and electronic coupons from the vehicle management server using an e-mail address that is known in advance by the vehicle management server.

The in-vehicle device collects data on engine on/off status, engine speed, etc., and sends it to the vehicle management server. A timer is also connected to the engine, and this timer also communicates serially with the vehicle unlock sensor.
The vehicle is also equipped with a driver's door sensor that detects whether the driver's door is open or closed, and a seating sensor that detects whether the driver is sitting in the driver's seat, and the detection data from each sensor is sent to the on-vehicle device.

(Figure 2)
FIG. 2 shows an algorithm that prevents the engine from starting if the member user unlocks the door using an IC card and does not start the engine after a predetermined period of time has elapsed even though the engine can be started. .

A member user arrives at the service target vehicle (reserved vehicle) related to the reservation (S1). Then, the door is unlocked using an IC card that identifies the individual member user. At this time, the vehicle unlock sensor notifies the vehicle-mounted device that the vehicle has been unlocked. Thereafter, the member user can start the engine (S2). At this time, a timer that generates a trigger when a predetermined time has elapsed starts counting (S3). Then, the driver's door sensor detects whether the driver's door is closed (locked) (S4). When the driver's door is closed, the timer is reset (S5) and the timer starts counting again (S3).

If the driver's door sensor detects that the driver's door is not closed, the engine sensor detects whether the engine is started or stopped (S6). If the engine is stopped, it is verified whether or not the time for the timer to generate a trigger has elapsed (S7). If the trigger generation time has elapsed, the on-vehicle device controls the engine so that it cannot be started (S8), and stops the timer measurement (S9).
If the engine has been started (S6), the on-vehicle device controls the engine so that it cannot be started (S8), and stops measurement by the timer (S9).

If it is estimated that no one is in the vehicle to be serviced after a predetermined period of time has elapsed, the engine is locked to prevent it from starting, or the engine that was running is stopped and locked. This prevents the service target vehicle from being stolen.
The member user can unlock the engine using the IC card associated with the member user who reserved the service target vehicle, and restart the engine.

(Figure 3)
FIG. 3 shows an algorithm that prevents the engine from being started when it is determined that the member user leaves the service target vehicle after stopping the engine and a predetermined time has elapsed.

It is assumed that a member user is driving a service target vehicle (reserved car) related to a reservation (S11) and stops the engine (S12). The driver's door sensor detects whether the driver's door is closed (locked) (S13). If it is not closed, it continues to detect whether it is closed or not.

If the driver's door is closed, the timer starts measuring (S14). After the timer starts measuring, the driver's door sensor again detects whether the driver's door is closed (S15). If it is closed, the timer is reset (S16), and the process returns to the start of timer measurement (S14).

If the driver's door sensor detects that the driver's door is not closed, the engine sensor detects whether the engine is on or off (S17). If the engine is turned off, it is verified whether the timer has expired (S18). If the timer has not expired, the process returns to S15.

If the timer has expired, the engine is locked so that it cannot be started (S19), and the timer measurement is stopped (S20). That is, if the driver's door is not closed even after a predetermined period of time has elapsed, the engine cannot be started, thereby preventing theft of the serviced vehicle.

(Figure 4)
FIG. 4 shows a procedure in which, when a member user gets into a keyless shared car, the multifunctional car navigation device explains how to start the engine of the keyless shared car.

In the vehicle management server, ride records are accumulated for each user, and the number of rides in the keyless shared car is also recorded. Additionally, vehicle type data is also stored, such as whether the vehicle involved in the reservation is a keyless shared car or not. Therefore, by referring to the vehicle type data from the vehicle database and the experience data from the member database, the data transmitting/receiving means sends "message not required" in advance to the keyless shared car (1). Mr. B shown in this figure will explain this on the assumption that he has no experience of riding in a keyless shared car.

The vehicle management server sends a message to the in-vehicle device of the keyless shared car that Mr. B has reserved in advance to the effect that a message is required (1). When the date and time related to the reservation arrive, Mr. B uses his IC card to release the vehicle unlock sensor and gets into the keyless shared car related to the reservation (2). Once you get in the car, the multi-function car navigation system will play a message saying that you can start the engine with an IC card even if you don't have the engine key, and will play a video of the necessary actions (3). After viewing the audio output and video, Mr. B starts the engine (4). Thereafter, various data such as information indicating that the engine has been started are transmitted as management data to the vehicle database of the vehicle management server and stored (5).

If the user is Mr. A, who has ridden in a keyless shared car twice, the vehicle management server will send a message to the keyless shared car that Mr. A has reserved to the effect that it is not necessary to output a message. It has been sent in advance. This saves Mr. A the time to listen to messages or watch videos about the keyless shared car engine starting process, which he already knows.

(Figure 5)
FIG. 5 conceptually shows how the user can more accurately determine whether to lock the engine by providing a trunk door opening/closing sensor and a weight sensor inside the trunk.

Assume that the trunk door is open and the weight sensor inside the trunk changes, such as becoming heavier or lighter within a predetermined period of time. In that case, even if the driver's door is not locked and the engine is stopped, there is very little need to lock the engine to prevent theft. Therefore, if it can be determined that a member user is loading or unloading luggage, the algorithm is such that timers and the like are reset so as not to lock the engine (flow chart is omitted).

(Figure 6)
FIG. 6 conceptually shows how the algorithm regarding whether to lock the engine is established by receiving the member user's intention to return the keyless shared car.

The keyless shared car is equipped with a GPS and intermittently transmits current position data to the vehicle management server via the on-vehicle device (1, 2).
On the other hand, in the vehicle management server, scheduled return times are stored as reservation data in the member database, and return location data is stored in the vehicle management database. Assume that the current position data received by the vehicle management server is near the return location data, and the current time is approaching the scheduled return time (2).

If the above conditions are met, the data transmitting/receiving means transmits a return button display command to the in-vehicle device of the keyless shared car (3). The in-vehicle device outputs a return button display command to the multi-function car navigation device. Then, a "Return" button and a "Do not return yet" button are displayed on the touch panel on the screen.

When a member user touches the "return" button, that fact is transmitted to a timer that controls engine locking. The keyless shared car will be returned to the return location soon, the engine will be turned off, and the member user's use will end, so the algorithms shown in FIGS. 2 and 3 will not be adopted when the use ends. Although the flow chart is omitted, even if the member user forgets to close the driver's seat door, all doors including the driver's seat door are locked and no one other than the member user associated with the next reservation can open the door.

In addition, in this figure, the current location display does not overlap with the return location display, that is, the reason why the above "return button display" is executed before the shared car arrives at the return location is because the return button is displayed before the shared car arrives at the return location. Because there are situations where it is difficult to communicate between the vehicle management server and the in-vehicle device, such as when the parking lot is located inside a building, this service is intended to complete data transmission and reception at a location where the shared car can communicate. be.

(Figure 7)
FIG. 7 shows a control procedure when a seating sensor that can detect whether a driver is seated in the driver's seat is installed.
A seating sensor is used instead of the door opening/closing sensor used in FIG.

When the member user arrives at the keyless shared car related to the reservation (S21) and unlocks it with the IC card, the engine becomes ready to start (S22). In this state, the timer starts measuring (S23).

Next, whether the engine is turned on or off is detected (S24). If the engine is not running, the seating sensor is used to detect whether a member user is seated in the driver's seat (S25). If it is determined that the user is seated, the timer is reset (S26) and the timer starts counting again (S23).

If it is determined that the user is not seated, it is detected whether a predetermined time set by the timer has expired (S27). If the time limit has expired, the engine is controlled so that it cannot be started (S28). If the timer has not expired, the process returns to the step (S24) of determining whether the engine is running.
After controlling the engine so that it cannot be started, the timer is stopped (S29) and the process ends (S30).

According to this control procedure, even if the keyless shared car is left unlocked and left without getting into the car, the timer will function and the engine will not start after a predetermined period of time. This prevents keyless shared cars from being stolen.
Further, in the case where the member user does not start the engine while seated, it is possible to prevent a situation in which the engine does not start after a predetermined period of time has elapsed.

Based on FIG. 7, the following third invention can also be provided.
