AI Technical Summary

⚠Technical Problem

The existing torque distribution calibration method cannot reasonably distribute the total drive torque to the three motors, resulting in low system efficiency and failure to fully utilize the performance advantages of the three motors.

⚗Method used

Based on the current torque distribution values ​​of the first and second motors and the torque distribution radar, the next torque distribution value of the three-motor drive system is determined, and simulation test calibration is performed. Finally, real vehicle calibration is performed to determine the final torque change rate and achieve reasonable torque distribution.

🎯Benefits of technology

This improved system efficiency, enhanced the vehicle's economy and drivability, and ensured the rationality and stability of torque distribution.

Abstract

This invention relates to the field of vehicle control technology, providing a torque distribution calibration method and components for a three-motor drive system. It solves the problem in existing technologies of how to rationally distribute torque among the three motors through calibration parameter settings to fully leverage the performance advantages of a three-motor drive system. The method first determines the next torque distribution value for the three-motor drive system based on the current torque distribution values ​​of the first and second motors, the torque distribution radar values ​​of the first and second motors, and the total drive torque. Then, it performs simulation testing to calibrate the next torque distribution value, obtaining the final torque calibration result for the three-motor drive system. Finally, it performs real-vehicle calibration on the final torque calibration result to determine the final torque change rate of the three-motor drive system. This method can rationally distribute the torque changes of the three motors, resulting in high system efficiency while improving the overall vehicle's economy and drivability.
