Abstract:A virtual simulation development platform (VSDP) was used to investigate the control strategy and vehicle performance of a dual axle coupling based 4-wheel-drive (4WD) plug-in hybrid electric vehicle (PHEV). Firstly, the composition and function of the VSDP were introduced, and the validity and accuracy of platform modeling analysis were ensured through the comparative analysis and verification of simulation data and real vehicle test. Secondly, using power flow and lever analysis method, the dynamic characteristics of the target system were analyzed, and the torque and speed transfer formulas under each driving mode were obtained. Based on the configuration of the target system, the vehicle dynamic system modeling was finished by using the VSDP. The driving strategy and mode switching control strategy of core components under each driving mode were developed and a dynamic coordinated control algorithm based on efficiency optimization was proposed. The research results verify the validity of the proposed vehicle driving strategy. Based on the analysis on the characteristic curves with/without dynamic coordinate control of dual motors, it is discovered that the proposed algorithm achieves the optimal control of the motor, and improves the efficiency by 4.26%.
