In this paper the single control system structure for the Adaptive Cruise Control (ACC) and Stop&Go applications is described in detail. This architecture is based on the idea of considering the vehicle system as an acceleration servomechanism requested by the controller, therefore first, a desired longitudinal acceleration is calculated from output data of the radar sensor, from vehicle speed and from driver commands. Secondly, the controller calculates a required acceleration to guarantee the achievement of the desired acceleration. Thirdly, to manage the actuators, the required acceleration is converted into a throttle opening angle request or into a brake pressure request. This system was installed on a test vehicle and results from on the road are provided.
