An adaptive cruise control system includes a forward-looking sensor generating a range signal corresponding to a distance between the host vehicle and a target vehicle. The forward-looking sensor also generates a range rate signal corresponding to a rate that the distance between the host vehicle and the target vehicle is changing. A controller is electrically coupled to the forward-looking sensor. The controller maintains a preset headway distance between the host vehicle and the target vehicle by adjusting the host vehicle velocity in response to the range signal and the range rate signal. The host vehicle may come to a full stop when the target vehicle is acquired below a predetermined velocity. If the target vehicle is acquired above the predetermined velocity, then a warning is given when braking is required.

A method of adjusting the velocity of a host vehicle comprising: sensing a target vehicle and generating a range signal corresponding to a distance between the host vehicle and said target; generating a range rate signal corresponding to a rate said distance between the host vehicle and said target vehicle is changing; maintaining a preset headway distance between the host vehicle and said target vehicle, in response to said range signal and said range rate signal; stopping said host vehicle when said target vehicle stops and said target vehicle was acquired below a predetermined velocity; and activating a warning when said target vehicle stops and said target vehicle was acquired above said predetermined velocity. 17. A method as in claim 16 further comprising maintaining a headway distance between the host vehicle and said target vehicle, from an initial vehicle rest velocity of zero KPH, in response to said range signal and said range rate signal. 18. A method as in claim 16 further comprising stopping said host vehicle when said target vehicle stops and said target vehicle did not exceed a predetermined velocity. 19. A method as in claim 16 further comprising activating a warning when said target vehicle stops and said target vehicle exceeded said predetermined velocity.
