With advantages like high efficiency, low pollution, and convenience of structure layout, the electric vehicles have been developing to become the main research direction of the automobile industry. Compared with the traditional centralized drive mode, the distributed electric drive can improve the power transmission efficiency and the fault tolerance. As the distributed electric drive technology developing in the field of multi-axle vehicles, research for mature dynamic coordinated control strategy has been an important task of the researchers in the automobile industry. This paper was aimed at the dynamic coordinated control strategy of multi-axle vehicles. Due to the independent driving characteristics of distributed drive multi-axle vehicles, a lateral dynamic control method using electronic differential moment power steering was proposed and verified, which can improve driving reliability, steering performance and vehicle mobility. A control model of six-axle-distributed-electric-drive vehicle was set up. With the MATLAB/Simulink software, the C code of the control model was generated and eventually burnt into the vehicle control unit (VCU). Then the hardware-in-the-loop experiment was successfully implemented on the motor bench, verifying the feasibility of the control algorithm.
