Abstract: A vehicle and its driving system is modeled with the input of its two side motor's objective rotary speed.Speed-regulation driving dynamic control scheme and algorithm has been designed and modeled in Simulink/Stateflow,and system simulation under different typical work conditions is achieved with the driver's inputs and control algorithm in-loop.Validity and effectiveness of speed-regulation control strategy is approved by simulation and the field experiments.The control strategy has been applied successfully in vehicles.
