| Abstract: | Aimed at the security and the comfort capability request,the car cruise system(CCS) based on free scale single chip was designed.The system estimate the difference of the set car speed and the actual car speed,adopt the PID arithmetic,control the valve of the accelerograph in closed loop.And the CAN bus interface was designed,make the communication with other electronic system on the car conveniently.This system can keep the car speed automatically,lighten the drive tire,and improve the security of the car. |
