1. A vehicle platform on which an autonomous driving system is mountable, the vehicle platform comprising:
a vehicle; and
a vehicle control interface box that interfaces between the vehicle and the autonomous driving system, wherein
the vehicle platform includes as a vehicle mode,
a manual mode in which the vehicle platform is under control by a driver, and
an autonomous mode in which the vehicle platform is under control by the autonomous driving system,
the vehicle platform includes as a power mode,
a sleep mode in which vehicle power is in an off condition,
a wake mode in which the vehicle control interface box is awake, and
a drive mode in which the vehicle power is in an on condition,
the vehicle control interface box is configured to receive, from the autonomous driving system, a vehicle mode request that requests control of the vehicle mode and to provide the autonomous driving system with a readiness-for-autonomization signal indicating whether the vehicle platform is ready for the autonomous mode, and
when the vehicle control interface box receives the vehicle mode request that requests the autonomous mode, the power mode is set to the drive mode, and the readiness-for-autonomization signal indicates readiness for the autonomous mode after the vehicle control interface box authenticates the autonomous driving system, the vehicle control interface box has the vehicle mode make transition from the manual mode to the autonomous mode.
