Claims

1. A stop-hold release control unit performs stop-hold control to activate the brake device when the vehicle is stopped to keep the vehicle in a stopped state, and performs release control to release the stop-hold by the brake device when a predetermined release condition is met during the execution of the stop-hold control, An operation input acquisition unit that acquires operation input from the driver of the vehicle, A driver abnormality determination unit that determines whether the driver is in an abnormal state, When the release control is executed by the stop-hold release control unit and the vehicle enters a state where it is necessary to stop and hold by the driver's operation, and the operation input acquisition unit does not acquire the driver's operation input, the system includes a determination correction unit that makes it easier for the driver abnormality determination unit to determine that the driver is in an abnormal state, or performs a determination correction that causes the driver to determine that the driver is in an abnormal state. Vehicle control system.

2. A vehicle control device according to claim 1, The vehicle further comprises an automatic driving control unit capable of performing automatic driving control to automatically drive and stop the vehicle, The stop-hold release control unit executes the stop-hold control when the vehicle is automatically stopped by the automatic driving control. Vehicle control system.

3. A vehicle control device according to claim 1 or 2, The system further includes a driver change request processing unit that, when the aforementioned release condition is met, executes a driver change request processing that requests the driver to take over driving, The stop-hold release control unit executes the release control if the operation input acquisition unit does not acquire the operation input for a predetermined first threshold time or longer from the start of the operation change request process. Vehicle control system.

4. A vehicle control device according to claim 3, The determination correction unit executes the determination correction if the state in which the operation input acquisition unit does not acquire the operation input continues for a predetermined second threshold time, which is longer than the first threshold time, from the start of the execution of the driver change request process. Vehicle control system.

5. A vehicle control device according to claim 3, The aforementioned brake device is a hydraulic brake device, The system further includes a backup control unit capable of performing backup control to activate an electric parking brake device and / or a parking lock device that holds the vehicle in a stopped state, The driver change request processing unit executes the driver change request processing when the release condition is met and the backup control unit is in a predetermined state where it cannot perform the backup control. Vehicle control system.
