Abstract:

The motion law of the centroid of vehicles can best embody the current vehicle's own motion.In the course of driving,the centroid of vehicle changes constantly and is difficult to position accurately.This article simulates the centroid movement of vehicle by using of Carsim.The set road curve can be regarded as the benchmark and the tested vehicle travels along the specified route.The simulation results are compared and analyzed.The test results show that one can identify the motion of the vehicle by the relative speed between wheel speed and systemic velocity.

Key words: centroid;carsim;motion state
