Abstract:

When using the traditional method to control the drive system of new energy vehicles， there is no speed deviation， resulting in the problems of slow speed， high wheel slip rate， unstable vehicle centroid displacement and high motor torque. Therefore， under the condition of spatial geometric constraints， the unified coordinated control method of new energy vehicle drive system is proposed. Firstly， the drive system model of a new energy vehicle is constrained by spatial geometry method to find and repair the fault. After the repair， the system power frequency domain of the new energy vehicle without coordinated control is analyzed， and the conclusion is obtained that the angular velocity difference of the new energy vehicle will change with the total input torque difference. Then， the engine torque of the new energy vehicle is transmitted to the transmission， the transfer function of the drive system is obtained， and the reason for the decline of the power performance of the drive system is obtained. Finally， the dynamic coordinated control method is used to regulate the speed deviation of new energy vehicles to realize the coordinated control of the drive system. The experimental results show that by the proposed control method， the speed of the new energy vehicle is relatively fast， the slip rate of the driving wheel is low， the vehicle centroid displacement is stable， and the motor torque is lower. It is proved that the proposed method can control the drive system of the new energy vehicle with good stability performance.
