The traditional regenerative braking control strategy usually uses the torque control mode and does not perform closed-loop control on the charging current, when the vehicle needs to be charged with a small current, the regenerative braking system cannot work effectively. The dual-mode regenerative braking control strategy proposed in this paper unifies the closed-loop control of regenerative current and the closed-loop control of regenerative torque. Especially when the battery is in a state of high charge or the temperature of the battery is too high or too low, this strategy can ensure charging safety, regeneration efficiency, and ride comfort. In the current closed-loop control mode, this proposal uses the ADRC controller to dynamically adjust the motor torque to achieve the purpose of accurately controlling the regenerative current. This method does not need to change the original vector control frame of the motor, which is convenient for engineering applications. The designed regenerative control strategy is verified through typical braking simulation. Bench tests are carried out and the results validate the feasibility and effectiveness of the designed strategy. Based on the realization of the safety of charging and the vehicle ride comfort, the proposed regenerative braking control strategy can achieve higher regeneration efficiency under the dynamical limitation of battery charging current, which further expands the operating range of the regenerative braking system.

传统的再生制动控制策略通常采用转矩控制方式，不对充电电流进行闭环控制，当车辆需要小电流充电时，再生制动系统无法有效工作。本文提出的双模式再生制动控制策略将再生电流的闭环控制与再生转矩的闭环控制统一起来。特别是当电池处于高充电状态或电池温度过高或过低时，此策略可以确保充电安全性，再生效率和乘坐舒适性。在电流闭环控制模式下，该建议使用ADRC控制器动态调节电动机转矩，以达到精确控制再生电流的目的。该方法无需更改电机的原始矢量控制框架，方便工程应用。通过典型的制动仿真验证了所设计的再生控制策略。进行了基准测试，结果验证了所设计策略的可行性和有效性。在实现充电安全性和车辆行驶舒适性的基础上，提出的再生制动控制策略在电池充电电流的动态限制下可以实现较高的再生效率，从而进一步扩大了再生制动系统的工作范围。通过典型的制动仿真验证了所设计的再生控制策略。进行了基准测试，结果验证了所设计策略的可行性和有效性。在实现充电安全性和车辆行驶舒适性的基础上，提出的再生制动控制策略在电池充电电流的动态限制下可以实现较高的再生效率，从而进一步扩大了再生制动系统的工作范围。通过典型的制动仿真验证了所设计的再生控制策略。进行了基准测试，结果验证了所设计策略的可行性和有效性。在实现充电安全性和车辆行驶舒适性的基础上，提出的再生制动控制策略在电池充电电流的动态限制下可以实现较高的再生效率，从而进一步扩大了再生制动系统的工作范围。
