Integrated queue assist and adaptive cruise control

A adaptive cruise control system for a host vehicle comprising:

• a forward-looking sensor generating a range signal corresponding to a distance between the host vehicle and a target vehicle;
• said forward-looking sensor generating a range rate signal corresponding to a rate that said distance between the host vehicle and said target vehicle is changing;
• and
• a controller electrically coupled to said forward-looking sensor and acquiring said target vehicle, said controller including control logic operative to maintain a preset headway distance between the host vehicle and said target vehicle from a host vehicle velocity of zero KPH, by adjusting the host vehicle velocity in response to said range signal and said range rate signal, stopping said host vehicle when said target vehicle stops and said target vehicle did not exceed a predetermined velocity, and activating a warning when said target vehicle stops and said target vehicle exceeded said predetermined velocity.

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.
