In order to improve the power performance of dual-motor vehicles with front and rear axles,the influence of the change of the transmission ratio of front and rear axles on the acceleration performance was studied,and the comprehensive evaluation was made based on the energy consump-tion.The research results show that:Cruise software is used to simulate different sets of transmission ratios and compare the results.The optimal set of front-rear shaft transmission ratios is selected,the acceleration time of 100 km is increased to 7.49s,the energy consumption in NEDC cycle condition is 1.38kWh,and the maximum speed and maximum climb are improved.
