In modern warfare

intelligent car conduct autonomous operations instead of human in hazardous conditions

greatly reducing the risk of casualties.an intelligent car motor servo control system based on CAN bus is designed

CAN bus technology principle

and function modules are introduced

and DSP motor control module is analyzed.Software design methods are given

achieving the upper computer real-time precise control on motor actions.Remote operator can real-time master motor work through GUI interface

Omni-directional control of intelligent car motion is achieved.The system runs well on an intelligent car

motor can operate normally in complex environment

which has high practical value.
