VEHICLE AND VEHICLE CONTROL INTERFACE

A vehicle (1) is a vehicle on which an ADK (3) is mountable. The vehicle (1) includes: a VP (5) that controls the vehicle in accordance with an instruction from the ADK (3); and a VCIB (41) that serves as an interface between the ADK (3) and the VP (5). The VP (5) outputs a brake pedal position signal in accordance with an amount of depression of a brake pedal by a driver, and outputs a brake pedal intervention signal, to the ADK (3) through the VCIB (41). The brake pedal intervention signal indicates that the brake pedal (50) is depressed, when the brake pedal position signal indicates that the amount of depression is larger than a threshold value, and indicates beyond autonomy deceleration of the vehicle (1), when a deceleration request in accordance with the amount of depression is higher than a system deceleration request.
