In order to improve the limitation and accuracy of the calculation method of vehicle body speed which is commonly used in the study of vehicle dynamics control system from the non-driven wheel speed of vehicles, the dynamic and kinematic models of driving vehicle and wheel are established and A vehicle body speed algorithm based on driving wheel speed signal with adjustable weighting factor is proposed.The Matlab program with vehicle speed algorithm is compiled and the vehicle working conditions accelerated on different road surfaces are simulated.The simulation results are in good agreement with the test results, The credibility of the algorithm
