Abstract

In-wheel motor drive vehicle has the advantages of simple structure, high transmission efficiency and superior dynamic performance. The mobility and combat capability could be improved greatly with the in-wheel motor on the battlefield. Based on the in-wheel motor drive technology in an 8-wheeled vehicle, the handling stability of the vehicle has been analyzed in detail. A 23-DOF vehicle model has been established including body, suspension, wheel and tire and other systems based on vehicle dynamics. A simulation analysis model based on MATLAB/Simulink has been established and the effectiveness of the model has been verified. Based on hierarchical control structure, the superstratum control strategy based on sliding mode control and the substratum control strategy based on optimal control allocation have been established. The simulations under 2 working conditions including pulse and step and double line have been made. Through the simulation analysis, we can see that the proposed hierarchical control structure can improve the handling stability of the vehicle in the process of steering.
