Abstract
An adaptive cruise control (ACC) system (10) for a host vehicle (12) is provided. The ACC system (10) includes a forward-looking sensor (18) generating a range signal corresponding to a distance between the host vehicle (12) and a target vehicle. The forward-looking sensor (18) also generates a range rate signal corresponding to a rate that the distance between the host vehicle (12) and the target vehicle is changing. A controller (20) is electrically coupled to the forward-looking sensor (18). The controller (20) maintains a preset headway distance between the host vehicle (12) and the target vehicle, when the host vehicle velocity is less than about 40 KPH, by adjusting the host vehicle velocity in response to the range signal and the range rate signal. A method for performing the same is also provided.
