AI Technical Summary

Technical Problem

When the traditional disengagement mechanism malfunctions, the auxiliary drive motor cannot be completely disengaged or engaged, leading to motor damage.

Method used

Through the interaction between the vehicle controller, motor controller, and disengagement mechanism controller, state change commands and torque control commands are sent to ensure that the disengagement mechanism does not participate in the drive when a fault occurs, and the auxiliary drive motor remains in a dormant or working state to prevent back electromotive force from damaging the motor.

🎯Benefits of technology

This prevents damage to the auxiliary drive motor caused by a malfunction in the disengagement mechanism, ensuring the vehicle's power and driving experience.

Abstract

This application provides a torque control system, method, vehicle, and storage medium, belonging to the field of automotive technology. The system includes: a vehicle controller, a motor controller, and a disengagement mechanism controller. When the vehicle controller detects a state change request, it sends a state change command to the disengagement mechanism controller and a first mode change command to the motor controller. In response to the state change command, the disengagement mechanism controller controls the disengagement mechanism to switch states based on the state change command. When the disengagement mechanism fails to switch to the target state, the vehicle controller sends a torque control command to the motor controller. In response to the first mode change command, the motor controller controls the auxiliary drive motor to switch to the target mode, and in response to the torque control command, controls the output torque of the auxiliary drive motor to a preset torque value. This application prevents motor damage caused by disengagement mechanism failure and eliminates the need for vehicle speed limits, ensuring vehicle power and optimizing the driving experience.
