SYSTEM AND METHOD FOR INTEGRATING INTELLIGENT CRUISE CONTROL WITH AN ELECTRONICALLY CONTROLLED ENGINE. |
摘要 |
A system and method for integrating intelligent cruise control functions with traditional cruise control functions in an electronically controlled internal-combustion engine utilizes engine control modes as defined in the SAE J1922 and SAE J1939 specifications. In one embodiment, the speed control mode is utilized to broadcast a desired engine speed to automatically attain and maintain a desired following distance relative to a forward vehicle. In another embodiment, the engine speed/torque limit control mode is used to impose an upper limit on the traditional cruise control set speed to control the headway distance relative to a forward vehicle. The system and method relinquish control to traditional cruise control when no forward vehicle is detected. Another embodiment provides a control strategy similar to that defined by the J1922 and J1939 specifications to select the lower value as determined by the intelligent cruise control and traditional cruise control functions.
