FIG. 2 is a flow chart showing one embodiment of the stopping process executed by the body ECU 10 of the present invention.
In FIG. 5, the body ECU 10 determines that the vehicle speed is 0 in step S10.
Then, it is determined whether or not the condition of the security unset state and the absence of the shock detection unlock output is satisfied. The security unset state is a state in which a security set switch provided on the instrument panel is turned off so that a warning sound is not emitted from the alarm and the display 17 even if a person touches the door handle. . The shock detection unlock output is a signal for releasing a door lock when a shock such as a collision is detected by a sensor. If the condition of step S10 is not satisfied, step S10 is repeated. When this condition is satisfied, the process proceeds to step S12. In step S12, the body ECU 10 determines whether the shift lever position notified from the shift lock ECU 9 is in the parking range, or whether the ignition switch 1 is rotated from the off position to the on position and restarted. If this condition is not satisfied, step S14
The process proceeds to step S30 if established. Step S
At 14, it is determined whether or not the driver's door has been opened based on a notification from the driver's door ECU 5. If the driver's door has been opened, the process proceeds to step S16. If the driver's door has been closed, the process proceeds to step S20. In step S16, it is determined whether or not the ignition switch 1 is in a rotation-prohibited state from the ON position to the accessory position and is in a warning sound blowing state, and if this condition is not satisfied, step S1 is performed.
Then, the process proceeds to step S10. In step S14, whether the rear seat door or the passenger seat door is opened is not limited to the driver seat door. If the shift lever position is not in the parking range when the vehicle stops and the driver's door is opened, the steps S16 to S1 are initially performed.
In step S18, the body ECU 10 prohibits the ignition switch 1 from rotating from the ON position to the accessory position, causes the alarm and display 17 to emit a warning sound, and then proceeds to step S10. Next, when the process proceeds to step S16, the process directly proceeds to step S10. On the other hand, if the driver's seat door is closed in step S14, it is determined in step S20 whether the ignition switch 1 is in a rotation-prohibited state from the ON position to the accessory position and whether a warning sound is sounded. If this condition is satisfied, the warning is not required if the driver's door is closed. Therefore, in step S22, the prohibition of rotation of the ignition switch 1 from the ON position to the accessory position is released, and a warning sound is issued. To stop the noise. Thereafter, the process proceeds to step S24. Step S2
If the condition of 0 is not satisfied, the process proceeds directly to step S24. In step S24, it is determined whether or not the ignition switch 1 has been turned from the on position to the accessory position and the engine has been stopped from the driving state. When this condition is satisfied, the shift lever position is not in the parking range when the vehicle stops,
Since the ignition switch 1 is rotated and the engine is stopped, the process proceeds to step S26, where the body ECU 1
0 sends a command to the driver's seat door ECU 5 to cause the driver's door lock 2 to be deadlocked, to sound a warning sound from the alarm and the display 17, and to display a warning message, and then proceed to step S10. If the condition of step S24 is not satisfied, step S1
Go to 0. If the shift lever position is in the parking range in step S12, or if the ignition switch 1 is rotated from the off position to the on position and restarted, the process proceeds to step S30 since there is no problem. , To determine whether or not the warning sound is sounding,
If so, the sounding of the warning sound is stopped in step S32. Thereafter, in step S34, it is determined whether or not the rotation of the ignition switch 1 from the ON position to the accessory position is prohibited. If so, the rotation of the ignition switch 1 from the ON position to the accessory position is prohibited in step S36. Cancel. Further, the body ECU 10 proceeds to step S38.
It is determined whether or not the door unlock signal from the electronic key has been received by the receiver 15, and if the door unlock signal has been received from this electronic key, a command is sent to the driver's seat door ECU 5 in step S40. Then, the deadlock of the driver's door lock 2 is released, and the process proceeds to step S10. On the other hand, if the door unlock signal has not been received, it is determined in step S42 whether or not the driver's door lock 2 is in a deadlock state. The deadlock of the door lock 2 is released, and step S10
Proceed to. If it is not in the deadlock state, the process directly proceeds to step S10. As described above, when the shift lever position is outside the parking range and the ignition switch position is in the off position, the vehicle door is prohibited from being opened, so that the shift lever position is not in the parking range. Can be warned, and a key interlock function can be realized in a vehicle having a smart ignition system.
