1. A vehicle on which an autonomous driving system (ADS) is mountable, the vehicle comprising:
a vehicle platform (VP) that controls the vehicle in accordance with an instruction from the ADS; and
a vehicle control interface that serves as an interface between the ADS and the VP, wherein
the VP receives a first deceleration request in accordance with an amount of depression of a brake pedal by a driver, and receives a second deceleration request from the ADS through the vehicle control interface,
during an autonomous mode, the VP specifies a sum of the first deceleration request and the second deceleration request as a target deceleration of the vehicle,
the VP outputs, to the ADS through the vehicle interface, a brake pedal position signal in accordance with an amount of depression of the brake pedal by the driver,
the VP sets a brake pedal intervention signal to:
a first value to indicate that the brake pedal is not depressed, when the brake pedal position signal indicates that the amount of depression is smaller than a threshold value,
a second value to indicate that the brake pedal is depressed, when the brake pedal position signal indicates that the amount of depression is larger than the threshold value,
a third value to indicate that beyond autonomy deceleration of the vehicle has occurred, when the first acceleration request is larger than the second deceleration request, and
the VP further outputs, to the ADS through the vehicle interface, the brake pedal intervention signal that is set to one of the first value, the second value, and the third value.
