The invention provides an accelerator pedal opening degree control method and system for intelligent driving. The method comprises the steps that a multi-dimensional corresponding table of driving torque output by a whole vehicle, the vehicle speed and the pedal opening degree is established; the actual pedal opening degree of the whole vehicle is obtained, and a corresponding torque data value TrqCal is obtained through table look-up calculation according to the actual pedal opening degree and the multi-dimensional corresponding table; acquiring an actual torque value Trqact output by the whole vehicle, and calculating an absolute error Etrq between the corresponding torque data value TrqCal and the actual torque value Trqact; and whether the absolute error Etrq is smaller than a set threshold value or not is judged, and if yes, the actual pedal opening degree serves as the current equivalent accelerator pedal opening degree of the whole vehicle so that opening degree control can be conducted. The problem that a plurality of different data torque points of an existing intelligent driving vehicle correspond to the same accelerator pedal opening degree is solved, and the using safety of the intelligent driving vehicle can be improved.
本发明提供一种智能驾驶的加速踏板开度控制方法及系统,该方法包括:建立整车输出的驱动扭矩、车速和踏板开度的多维对应表;获取整车的实际踏板开度,并根据所述实际踏板开度和所述多维对应表查表计算得到对应扭矩数据值TrqCal;获取整车输出的实际扭矩数值Trqact,计算所述对应扭矩数据值TrqCal与所述实际扭矩数值Trqact的绝对误差Etrq;判断所述绝对误差Etrq是否小于设定阈值,如果是,则将所述实际踏板开度作为当前整车的等效加速踏板开度,以进行开度控制。本发明解决了现有智能驾驶车辆存在多个不同数据扭矩点对应相同加速踏板开度的问题,能提高智能驾驶车辆使用的安全性。
