[Prior art]
Various vehicle control devices have been developed that communicate with the vehicle side using electronic keys (electronic key members) such as portable IC cards to identify the driver and perform vehicle unlocking, engine start permission, etc. (See, for example, Japanese Patent No. 2970642). In this type of control device, when the communication between the electronic key and the vehicle is normally performed, the engine is allowed to start and the engine is started by performing a starting operation. If the communication between the electronic key and the vehicle side is interrupted due to some reason such as deterioration of the communication status or the electronic key moving away from the driver's hand, the engine cannot be restarted. Informs that the electronic key cannot be communicated.
[0003]
However, if the alarm is issued every time communication between the electronic key and the vehicle side is interrupted while the engine is operating, the operation is troublesome and hinders driving. For this reason, communication between the electronic key and the vehicle side is performed at multiple locations in the car, and it is assumed that the communication will not be interrupted in the car, so that no alarm is issued regardless of the communication status when the engine is operating. A vehicle control device is also known.
[0004]
[Problems to be solved by the invention]
However, if the alarm is not issued regardless of the communication status when the engine is operating, the engine cannot be started if the communication between the electronic key and the vehicle is interrupted. If the communication between the electronic key and the vehicle is interrupted due to a cause (for example, when the passenger goes out of the vehicle with the bag in the bag), the engine must be restarted after the engine is stopped. It will be impossible to start.
[0005]
The present invention has been made in view of the above situation, and an object of the present invention is to provide a vehicle control device that enables accurate engine control in a state where a driver is bringing an electronic key member.

It is controlled to the state of the car according to personal information such as.
[0018]
When the communication between the position antenna 24 and the electronic key 1 is interrupted while the engine operating state detecting means 27 detects the stop of the engine 30, the ECU 2 of the control device described above (the electronic key 1 is connected to the driver seat 23). A function of making it impossible to start the engine 30 when it is detected that the engine 30 does not exist in the vicinity. Thus, if the driver does not have the electronic key 1, the engine 30 cannot be started, and the driver brings the electronic key 1 while reducing the state in which the driver is separated from the electronic key 1. The engine 30 can be accurately controlled in the state.
[0019]
The ECU 2 also opens the door 25 by the door switch 26 when communication between the position antenna 24 and the electronic key 1 is interrupted while the engine 30 is operating (when the position of the electronic key 1 cannot be detected by the position antenna 24). When the event is detected (when the driver's intention to get off is detected), a function of outputting an operation command to the alarm device 28 is provided. As a result, alarms can be issued only when necessary, and frequent alarms can be prevented.
[0020]
Further, the ECU 2 is operated to stop the engine 30 when the communication between the position antenna 24 and the electronic key 1 is interrupted while the engine 30 is operating (when the position of the electronic key 1 cannot be detected by the position antenna 24). Sometimes, a function of outputting an operation command to the alarm device 28 is provided. As a result, alarms can be issued only when necessary to prevent frequent alarms, and a situation in which restarting is impossible in the future when the engine is stopped is avoided, and a person other than the driver holds the electronic key 1 outside the vehicle. Even when the engine 30 is stopped, the driver can recognize that the electronic key 1 is not present when the engine 30 is stopped, and can avoid a state in which the engine 30 cannot be restarted.
[0021]
At this time, if the stop operation of the engine 30 continues after the alarm device 28 is activated, a function of stopping the engine 30 after a predetermined time (for example, about 30 seconds) is provided. As a result, alarms can be issued only when necessary, and frequent alarms can be prevented.
[0022]
A control operation by the ECU 2 will be specifically described with reference to FIG.
[0023]
As shown in FIG. 3, after the initial setting is made in step S1, it is determined in step S2 whether or not the personal identification number of the electronic key 1 has been received via the antenna 3. That is, it is determined whether or not the electronic key 1 exists in the specific area 22. The determination in step S2 is repeated until the electronic key 1 is present in the specific area 22, and if the electronic key 1 is received via the antenna 3, the door lock is released via the door lock actuator 11 in step S3. That is, the driver can get into the vehicle 21. If the driver leaves the vehicle 21 without entering the vehicle 21, reception of the electronic key 1 is interrupted and the door is locked via the door lock actuator 11.
[0024]
Next, in step S4, it is determined whether or not the driver is seated in the driver's seat via the seating sensor 6. The determination of whether or not the driver is seated is repeated until it is determined that the driver is seated. When it is determined that the driver is seated, the fingerprint collation device 5 stands by in step S5, and voice guidance such as “Please collate the fingerprint” or this type Is displayed. After fingerprint collation is performed, it is determined in step S6 whether the fingerprint collation is OK (matched). Whether the fingerprint collation is OK or not is repeated until the fingerprint collation is matched. If the fingerprint collation is matched, the vehicle equipment control unit 9 and the personal equipment control unit 10 are operated and recorded (registered) in the electronic key 1 in step S7. It becomes the state of the vehicle according to the made vehicle state and personal information.
[0025]
Next, in step S8, it is determined whether or not the sheet position is OK (appropriate) via a timer or the like. The determination as to whether or not the seat position is OK is repeated until the seat position becomes appropriate. If it is determined that the seat position is OK, the engine switch 8 can be operated in step S9. In step S10, it is determined whether or not the seat belt is OK (attached) via the seat belt attachment sensor 7. The determination as to whether or not the seat belt is OK is repeated until the seat belt is attached. If it is determined that the seat belt is OK, the shift lever can be moved from the N range or the P range, and step S11 is performed. The door is locked through the door lock actuator 11.
[0026]
Thus, in this embodiment, even if the electronic key 1 is stolen, if the fingerprint verification does not match, the engine switch 8 cannot be operated and the vehicle 21 cannot run. 21 is never stolen. Further, since it is not necessary to register the fingerprint of the specific user in advance in the fingerprint collation device 5 provided in the vehicle 21, the commonality of the vehicle 21 is enhanced. In addition, convenience is enhanced by storing personal information such as a telephone number and mail memory in the electronic key 1.
[0027]
When the door is locked in step S11, it is determined in step S12 whether or not the engine 30 is in a non-operating state. If the engine operating state detecting unit 27 determines that the engine 30 is in a non-operating state, step S13 is performed. It is then determined whether the driver has the electronic key 1 or not. That is, in step S13, it is determined whether or not the electronic key 1 is received through the position antenna 24. If it is determined in step S13 that the driver has the electronic key 1, the start of the engine 30 is permitted in step S14 and the end is reached.
[0028]
If it is determined in step S13 that the driver does not have the electronic key 1, that is, if it is determined that the electronic key 1 is not received via the position antenna 24, the start of the engine 30 is not permitted in step S15. (Function to disable starting of engine 30). Then, in step S16, an alarm for not permitting the start of the engine 30 is activated to end. On the other hand, if it is determined in step S12 that the engine 30 is in an operating state, the process is ended as it is.
[0029]
Therefore, if the driver does not have the electronic key 1, the engine 30 cannot be started, and the state in which the driver and the electronic key 1 are separated and the driver is bringing the electronic key 1 is reduced. This makes it possible to control the engine 30 accurately.
[0030]
After the engine 30 is started, the interruption process during engine operation shown in FIG. 4 is executed at any time.
[0031]
As shown in FIG. 4, when the engine 30 is in operation, if the reception status of the electronic key 1 through the position antenna 24 is determined in step S21, and the reception of the electronic key 1 is determined to be bad, the step In S22, it is determined whether or not the door 25 is opened by the detection of the door switch 26. If the door 25 is not open in step S22, even if the reception of the electronic key 1 is bad, the driver determines that the driver is not willing to get off and the communication has just been interrupted due to some temporary cause. The alarm is not activated and ends.
[0032]
If it is determined in step S22 that the door 25 is opened, it is determined that the driver intends to get off, and an alarm indicating that reception of the electronic key 1 is defective is activated in step S23. This warning is given both inside and outside the vehicle. As a result, the alarm can be issued only when the reception of the electronic key 1 is poor and the driver is willing to get off the vehicle, that is, when necessary, so that frequent alarms can be prevented.
[0033]
Next, in step S24, it is determined whether or not there is a stop operation of the engine 30, that is, whether or not the engine switch 8 is turned off. If it is determined that there is a stop operation of the engine 30, the electronic key 1 The driver may not have brought the electronic key 1 because of the poor reception of the engine 30. If the engine 30 is stopped as it is, the engine 30 cannot be restarted next, so an alarm that the engine 30 cannot be restarted is issued in step S25. Operate. For example, a voice warning such as “The electronic key cannot be confirmed and the engine cannot be restarted. If you need help, turn the engine switch back on.” Is activated.
[0034]
After activating an alarm that the engine 30 cannot be restarted in step S25, it is determined in step S26 whether or not the stop operation of the engine 30 is interrupted, and it is determined that the stop operation of the engine 30 is interrupted. In this case, since the operation of the engine 30 is continued, the end. If it is determined in step S26 that the stop operation of the engine 30 has not been interrupted, the engine 30 is stopped after the predetermined time (for example, 30 seconds) has elapsed in step S27, and the process is ended.
[0035]
That is, when the operation of stopping the engine 30 is performed when the reception of the electronic key 1 is defective, the alarm is activated immediately without stopping the engine 30, and the operation is stopped after a time.
[0036]
Accordingly, an alarm can be issued only when necessary to prevent frequent occurrence of the alarm, and a situation where the engine cannot be restarted in the future when the engine 30 is stopped is avoided. Even when the engine 30 is taken outside the vehicle, the driver can recognize that the electronic key 1 is not present when the engine 30 is stopped, and can avoid a state in which the engine 30 cannot be restarted.
[0037]
