摘　　要：在研究结合整车应用场景和电驱转矩过0的整车防抖控制需求的基础上,本文从整车控制防抖的角度提出了包括传动间隙、转矩限制、电驱转矩过0以及转速波动高频去噪4个整车防抖控制需求和软件实现架构。基于防抖控制需求设计了电驱转矩过0的整车防抖控制算法架构及控制策略,并给出相应控制过程及计算分析。通过对所设计的防抖控制策略进行仿真及实车测试,证明该控制算法架构及算法策略能有效实现整车的防抖功能。同时根据实车测试车辆的纵向加速度曲线和电驱的转速波动值可知,所设计的算法架构及控制策略在车辆驾驶性上取得了很好的效果。Based on the research on the combination of vehicle application scenarios and electric drive torque near zero anti-jerk control requirements,in this paper four vehicle anti-jerk control requirements and their software architectures from the perspective of vehicle anti-jerk,including transmission clearance,torque limita-tion,electric drive torque near zero,and high-frequency de-noising of wheel speed fluctuation.Based on the re-quirements of anti-jerk control,vehicle anti-jerk algorithm architecture as well as the control strategy with electric motor torque near zero is designed,and the corresponding control process and calculation analysis are provided.Through simulation and real vehicle testing of the designed anti-jerk control strategy,it is proved that the control al-gorithm architecture and strategy can effectively achieve the anti-jerk function of the vehicle.According to the longi-tudinal acceleration curve of the real vehicle test and the fluctuation of the electric drive speed,it can be seen that the designed software architecture and control strategy have achieved good results in vehicle drivability.
