Abstract

The invention provides a dual-motor control system and method. When the dual-motor control system is used, a vehicle control unit generates and sends torque instruction information to a main motor according to an operation instruction so as to control the main motor to output main driving power, a transmission decelerates and increases torque of the rotating power received by the input end of thetransmission according to a speed change instruction sent by the vehicle control unit and then outputs the rotating power from the output shaft of the transmission. The output shaft of the transmission is connected with an auxiliary motor in a follow-up mode, the output shaft of the auxiliary motor is in transmission connection with a vehicle transmission shaft, and the auxiliary motor can providecertain auxiliary power for the vehicle transmission shaft. When large power is needed, two motors can provide power for the vehicle transmission shaft at the same time. When one motor breaks down, the other motor can provide power in a standby mode to enter a limp mode.

Description

technical field [0001] The present application relates to the technical field of vehicle motor control, in particular to a dual motor control system and method. Background technique [0002] In the current vehicle equipment, a single motor combined with a transmission is mostly used to output power to the vehicle transmission shaft. Although the power output in this process is direct and reliable, if the motor or transmission fails, the vehicle will not be able to run normally. Here comes a certain question. Contents of the invention [0003] In view of this, the present application provides a dual-motor control system and method. The motors of the dual-motor can operate independently or jointly to output power, and the whole structure has a high degree of integration. [0004] In the first aspect, a dual-motor control system provided by the present application includes: a vehicle controller configured to generate and send torque command information and a speed change com...
