A study was conducted to optimize the energy of an electric vehicle equipped with a two-motor and two-transmission system. Since different transmissions are applied to each motor, the speed and torque of the motor vary according to the gear ratio of each transmission. In the two-motor two-transmission system, it was confirmed that the efficiency characteristics of the motor vary not only with the gear stage but also with the torque distribution ratio of the motor. In this study, the optimum gear ratio and motor torque ratio were determined according to various driving conditions. The optimum operating mode of the power train system was obtained. WHVC and JE05 cycles were simulated using the analysis model. It was confirmed that power consumption was reduced by 4.1 % to 6.1 % compared to when the two motor torques were controlled equally using the optimization control. |
