Aiming at the trend for the future of the automobile autonomous driving and safe arriving at the destination, describe production scheme of an intelligent tracking electric vehicle with a digital camera. It has accelerated technology of image bi-naryzation to process track information; inertial navigation chip can detect and calculate car posture. The paper gives the smart car software system structure; analysis the control strategies and optimization. The results show that through optimal control strategy and the identification of road characteristics, it can run safely, rapidly and smoothly in the no-boundary track board. On the other hand, it also can safely drive through a ramp up and down within 15 degrees.
