The invention discloses a parking starting driving torque control method based on a steering wheel angle and gradient, and relates to the technical field of ramp parking starting control. According to the method, starting driving torque self-learning is carried out based on the steering wheel rotation angle and gradient information, the driving force needed by vehicle starting can be rapidly calculated, the vehicle starting smoothness is guaranteed, the vehicle starting rapidity is also guaranteed, and when the system is judged to be in the steady-state working condition, the torque value is adjusted according to the actual motion state of the vehicle, and self-learning is updated. The method is applied to a vehicle model with an automatic parking system, and vehicle starting leaping, slow starting and starting sliding caused by inaccurate torque calculation in the vehicle parking starting process are reduced.
本发明公开了一种基于方向盘转角和坡度的泊车起步驱动扭矩控制方法,涉及坡道泊车起步控制技术领域。本发明以基于方向盘转角和坡度信息进行起步驱动扭矩自学习,能够快速计算出车辆起步所需要的驱动力,既保证了车辆起步的平顺性,也保证了车辆起步的快速性,同时系统判断在稳态工况下,会根据车辆实际运动状态进行调整扭矩值并更新自学习;应用于带有自动泊车系统的车型中,减少车辆泊车起步过程中因为扭矩计算不准确导致的车辆起步蹿动,起步缓慢和起步溜车。
