摘要： A stop determination for a vehicle is provided by requiring simultaneous stop determinations by at least one wheel speed sensor providing output pulses at a rate inversely proportional to vehicle speed and a forward looking radar unit for sensing an object in the vehicle's path and providing a range rate signal with respect to that object. The determination is particularly useful when the time between consecutive pulses at a predetermined minimum speed indicative of an essentially stopped vehicle is greater than a predetermined maximum time period allowed for the determination. Each of the signals complements the other to provide a vehicle stopped determination that is more reliable than either can provide by itself and is workable for most purposes, including stop and go vehicle speed control.

摘要： A system and method for closed loop speed control for stop and go applications allowing adaptive cruise control operation at low speeds below vehicle idle speed by use of traction control system braking. The system comprises: proportional controller to hold the vehicle speed at the desired vehicle speed; integral controller to reduce vehicle speed when the adaptive cruise control cuts off speed control; stopped controller to overcome static friction after a vehicle stop; open loop controller to hold the vehicle speed a set speed below the vehicle idle speed. The system also provides a switch to set the torque command to zero for large positive speed control errors, such as when the desired speed is above the vehicle idle speed, and a transition logic to provide a smooth transition between alternate control mode operation and speed control mode operation.
