Abstract

The invention discloses a torque control system and method for a dual-motor electric vehicle and the dual-motor electric vehicle. The system comprises a vehicle control unit, a motor controller, a first motor module and a second motor module, the whole vehicle controller is in communication connection with the motor controller and is used for identifying the whole vehicle demand torque and sending the whole vehicle demand torque to the motor controller; the motor controller is electrically connected with the first motor module and the second motor module, and the motor controller is used for receiving the torque required by the whole vehicle; the real-time maximum output torque of the first motor module and the real-time maximum output torque of the second motor module are determined; and controlling the first motor module and/or the second motor module to output the vehicle demand torque according to the vehicle demand torque, the real-time maximum output torque of the first motor module and the real-time maximum output torque of the second motor module. According to the scheme, the optimal power output is controlled through the motor controller, the problem of data transmission delay is solved, the response efficiency is improved, and the dynamic experience of a driver and passengers is improved.

Description

technical field [0001] Embodiments of the present invention relate to a torque control technology for a dual-motor electric vehicle, in particular to a torque control system and method for a dual-motor electric vehicle and a dual-motor electric vehicle. Background technique [0002] The prospect of pure electric vehicles is widely optimistic due to their smaller impact on the environment than traditional vehicles. The control system of an existing dual-motor electric vehicle includes a front motor, a front motor controller, a rear motor, a rear motor controller, a high-voltage battery pack, a battery management system, and a vehicle controller. The power output response of the control system of the entire motor electric vehicle is slow, and the power torque control is not good. Contents of the invention [0003] The invention provides a torque control system and method for a dual-motor electric vehicle and a dual-motor electric vehicle, which realizes the control of the o...
