摘要： 为解决电动汽车在行驶过程中工况突变而导致的扭矩超限问题，文章基于意昂神州 （EON）的整车控制器（VCU）开发台架，设计了一种扭矩限制的控制策略。该策略通过查 表法完成初始需求扭矩计算，接着进行驱动扭矩限制和扭矩协调来完成扭矩输出，结合驱动 力—行驶阻力模型计算当前车速，再通过车速-转速关系反馈转速和车速作为查表法输入，形 成闭环控制，实现了输出扭矩的动态调整。然后使用 MATLAB/Simulink 搭建该策略控制模型， 将控制策略模型刷写到待测整车控制器中，将整车控制器与硬件在环（HIL）仿真台架连接， 通过 HIL 台架对 VCU 的控制逻辑进行验证。实验结果表明，该控制策略能够结合驾驶员意 图、车辆信息等对扭矩需求进行动态修正，最终输出符合安全标准且经过限制的电机扭矩， 以确保动力系统安全、高效运行。

Abstract: To address the issue of torque over-limitation in electric vehicles due to sudden changes in driving conditions, this paper is based on the vehicle control unit (VCU) development test bench of Eontronix (EON). This strategy calculates the initial required torque through a lookup table method, then performs drive torque limitation and torque coordination to complete torque output. The current vehicle speed is calculated using the driving force-driving resistance model, and the speed-rotational speed relationship is used to feedback the rotational speed and vehicle speed as the input for the lookup table method, forming a closed-loop control to achieve dynamic adjustment of the output torque. Then, the control model of this strategy is built using MATLAB/Simulink, and the control strategy model is flashed into the VCU to be tested. The VCU is connected to the hardware-in-theloop (HIL) simulation bench, and the control logic of the VCU is verified through the HIL bench. The experimental results show that this control strategy can dynamically correct the torque demand based on the driver's intention, vehicle information, etc., and ultimately output a motor torque that meets safety standards and is limited, ensuring the safe and efficient operation of the power system.
