The invention provides an AVH torque unlocking optimization control method under a multi-path working condition, and belongs to the technical field of electric vehicle torque control, and the method comprises the steps: detecting the normal starting of a whole vehicle driving function of a vehicle, and detecting the successful starting of an AVH function; a gradient sensor is used for measuring the gradient of a road, the gradient resistance of the road condition is calculated according to the measured gradient, the gradient resistance is analyzed, and the optimal torque output by the vehicle is calculated; the obtained optimal torque output by the vehicle is compared with the actual torque of the vehicle, and the obtained comparison result and the torque change rate serve as input data to be put into a model predictive control (MPC) torque estimation model for estimation; and according to an output result of the MPC torque estimation model, an instruction is sent to the vehicle to promote a power system of the vehicle to carry out torque output. According to the method, on one hand, the handover efficiency and comfort degree between the automatic driving vehicle and the manual driving vehicle are improved, and on the other hand, torque impact caused by AVH unlocking of the electric vehicle under different road conditions is reduced.

    本发明提供了一种多路工况下AVH扭矩解锁优化控制方法,属于电动汽车扭矩控制技术领域,包括:检测车辆的整车行驶功能正常启动,并且检测AVH功能成功开启;使用坡度传感器测量道路的坡度,将测量得到的坡度计算出路况的坡度阻力,并分析坡度阻力,计算得到车辆输出的最佳扭矩;将获得的车辆输出的最佳扭矩与车辆实际扭矩进行比较,将得到的比较结果以及扭矩变化率作为输入数据放入模型预测控制(MPC)扭矩估算模型中进行估算;根据MPC扭矩估算模型的输出结果,向车辆发送指令促使车辆的动力系统进行扭矩输出。本发明一方面提高了自动驾驶车辆与人工驾驶车辆之间的交接效率和舒适度,另一方面减小了电动汽车在不同路况下AVH解锁时带来的扭矩冲击。
