4. A vehicle control interface that interfaces between an autonomous driving system (ADS) and a vehicle platform (VP) that controls a vehicle in accordance with a control request from the ADS, the VP including an electric parking brake system that switches between activation and release of brakehold, the vehicle control interface comprising:
a processor; and
a memory in which a program executable by the processor is stored, wherein
the processor is configured to:
provide the ADS with a standstill status signal including a first value indicating activation of the brakehold and a second value indicating release of the brakehold, and
receive, from the ADS, a standstill command, the standstill command being generated by the ADS in accordance with a driving plan created by the ADS, the standstill command including a third value, indicating allowing the brakehold and requesting to apply the brakehold, or a fourth value, indicating not allowing the brakehold,
receive, when the ADS outputs the standstill command including the third value, a request for the VP to decelerate, and
in response to the standstill status signal switching from the second value to the first value, the processor continues to receive requests from the ADS to decelerate during an entire period for which the brakehold is active.
