Vehicle control device
When a driver is in an abnormal state, a vehicle control device executes a stop control of applying a braking force to a vehicle to stop the vehicle and a stop holding control of holding the vehicle in a stopped state after stopping the vehicle with the stop control. The control device is configured to prohibit the stop holding control from being released, when a first condition that is satisfied when an operation amount of an accelerator operator is larger than a predetermined threshold value is satisfied, while the stop holding control is being executed.
1. A vehicle control device comprising:
a sensor that acquires information about an operation amount of a driving operator operated by a driver of a vehicle to drive the vehicle, the driving operator at least including an accelerator operator operated to accelerate the vehicle; and
a control device that is configured to
repeatedly determine whether the driver is in an abnormal state in which the driver has lost an ability to drive the vehicle while the vehicle is traveling, based on the information about the operation amount of the driving operator,
execute a stop control of applying a braking force to the vehicle to stop the vehicle, when a determination that the driver is in the abnormal state is continued, and
execute a stop holding control of holding the vehicle in a stopped state by continuously applying the braking force to the vehicle after the vehicle is stopped by the stop control, wherein
the control device is configured to:
determine whether a first condition is satisfied, wherein the first condition is satisfied when the operation amount of the accelerator operator is larger than a predetermined threshold value, while the stop holding control is being executed;
determine whether a second condition is satisfied, wherein the second condition is satisfied when a probability is high that the driver is currently being rescued, while the stop holding control is being executed;
prohibit the stop holding control from being released, when both (i) the first condition is satisfied and (ii) the second condition is satisfied;
when either one of the first condition is not satisfied or the second condition is not satisfied, determine whether a predetermined release operation for releasing the stop holding control is being performed;
release the stop holding control, when the following conditions are met: (i) the first condition is satisfied, and (ii) the second condition is not satisfied, and (iii) the predetermined release operation is being performed, while the stop holding control is being executed; and
release the stop holding control, when the following conditions are met: (i) the first condition is not satisfied, and (ii) the second condition is not satisfied, and (iii) the predetermined release operation is being performed, while the stop holding control is being executed.
2. The vehicle control device according to claim 1 , wherein the control device is configured to determine that the second condition is satisfied, when at least one of the following is satisfied: aa condition that a door corresponding to a seat of the driver is open, or (ii) a condition that a seat belt of the seat of the driver is in a released state.
