1. A vehicle comprising:
a vehicle platform on which an autonomous driving system is mountable, wherein
the vehicle platform includes:
a brake device configured to apply braking force to a wheel of the vehicle; and
a control device configured to control the brake device,
the autonomous driving system sends to the vehicle platform a command including a first command to request acceleration and deceleration and a second command to request to maintain stationary,
the autonomous driving system obtains a first signal indicating a longitudinal velocity of the vehicle and a second signal indicating whether the vehicle is at a standstill,
when the first signal indicates 0 km/h or a prescribed velocity or less after the autonomous driving system issues the first command to request the vehicle platform to provide deceleration to stop the vehicle, the autonomous driving system issues the second command to request the vehicle platform to maintain stationary,
when the first command requests deceleration and the second command requests the vehicle to be maintained stationary, the control device performs brake hold control by the brake device,
when the brake hold control is completed, the second signal indicates standstill,
the autonomous driving system further obtains a third signal indicating a moving direction of the vehicle,
the third signal indicates standstill when a prescribed number of wheels of the vehicle continue a speed of zero for a prescribed period of time, and
while the brake hold control is being performed, the control device determines whether the brake device continues the brake hold control based on the first command, the second command, and the third signal.
