AI Technical Summary
Technical Problem
When new energy electric vehicles brake on curves on icy, snowy, or gravel roads, the wheels are prone to lock up, causing the vehicle to lose steering ability or skid and fishtail. Existing technology is difficult to effectively reduce the risks caused by wheel slippage.
Method used
The intelligent integrated braking system (IPB) detects wheel slip ratio and sends torque control commands to the motor controller. The motor controller controls the motor torque based on the slip ratio and uses a PID control algorithm to eliminate wheel slippage and improve vehicle stability.
Benefits of technology
It responds quickly to wheel slippage, preventing vehicle skidding and fishtailing, improving driving stability, and completing torque control faster than traditional methods.

Abstract
本发明提供一种分布式拖滞扭矩控制方法、系统及可读存储介质。分布式拖滞扭矩控制方法包括：当车辆处于能量回收状态时，智能集成制动系统IPB检测是否存在处于打滑状态的异常车轮；当存在异常车轮时，IPB发送所述异常车轮的滑移率以及扭矩控制指令至电机控制器；电机控制器基于所述异常车轮的滑移率对所述异常车轮的电机的扭矩进行控制。通过本发明，当车轮打滑时，根据异常车轮的滑移率对异常车轮的电机的扭矩进行控制，从而消除车轮打滑导致的车辆侧滑失稳问题，提升车辆的行车稳定性。且，是直接通过电机控制器对异常车轮的电机的扭矩进行控制，相较于通过IPB进行扭矩控制的方式，能更快的完成扭矩控制。
