The invention belongs to the technical field of automobiles, and discloses an electric automobile accelerator pedal atlas calibration method which mainly takes a driving mode selected by a current driver, driver accelerator pedal opening degree information, current automobile speed, accelerator pedal opening degree change rate and other automobile state information and automobile parameters as judgment conditions. And determining data of the pedal atlas, then determining a first torque value, obtaining a second torque value according to the torque coefficient, and further optimizing the second torque value to obtain an output final torque value. According to the method for matching the torque required by the driver of the electric vehicle with the accelerator pedal, the torque required by the driver of the electric vehicle and the accelerator pedal are matched, and the torque required by the driver of the electric vehicle and the state of the vehicle are analyzed and calculated through a vehicle controller. Different driving torques can be output according to different driving modes and pedal opening degrees in the vehicle running process, so that the driving requirements of a driver in different driving modes are met.
本发明属于汽车技术领域,本发明公开了一种电动汽车加速踏板图谱标定方法,主要以当前驾驶员选定的驾驶模式、驾驶员油门踏板开度信息、当前车速及油门踏板开度变化率等车辆状态信息及车辆参数为判断条件,根据车速和踏板开度,确定踏板图谱的数据,再确定第一扭矩值,根据扭矩系数,得到第二扭矩值,对第二扭矩值作进一步优化得到输出最终扭矩值。结合电机外特性扭矩表现,控制电机输出对应的驱动扭矩,提高各模式下整车驾驶性,它是一种电动汽车驾驶员需求扭矩与加速踏板的匹配方法,通过整车控制器对加速踏板及车辆状态的分析计算,能够在车辆行驶过程中根据不同驾驶模式及踏板开度输出不同驱动扭矩,来满足驾驶员不同驾驶模式下的驱动需求。
