Abstract: A vehicle dynamic model was established for the humanvehicle closeloop system to analyze the vehicle stability.Two direct yaw moment control(DYC) strategies,i.e.,the feedforward and single neuron PID control strategies were proposed to ensure the zero sideslip angle of the mass center.Through the simulation at low adhesion roads with double lane change,the two control strategies were compared.The seiulation results show that the single neuron DYC control strategy can more effectively control the wheel and vehicle motion,improve the lateral and longitudinal stability of the vehicle.

Key words: vehicle engineering, direct yaw moment control(DYC), humanvehicle closedloop system, neural network, stability control
