The invention discloses a driving torque acquisition method for an electromechanical coupling dual-clutch hybrid power system. The method comprises the following steps of: firstly, differently correcting an accelerator pedal opening degree obtained after a driver steps on the same accelerator pedal according to a current whole vehicle working mode to obtain a corresponding accelerator value; thenmapping the corrected pedal opening degree to a corresponding opening degree interval set according to a calibration value; calculating a driving torque according to the torque values of the upper limit and the lower limit of the interval and the proportion of the corrected accelerator pedal in the corresponding interval, and finally performing secondary correction on the driving torque to obtainwheel end output torque and outputting the wheel end output torque to realize driving torque collection. The influence of temperature, driver operation and whole vehicle faults is comprehensively considered, and the obtained wheel end required torque is closer to the actual working condition.

    一种用于机电耦合双离合混合动力系统的驾驶扭矩采集方法,首先根据当前的整车工作模式对驾驶员踩相同油门踏板之后得到的油门踏板进行不同的修正,得到对应的油门值;然后将修正后的踏板开度映射至根据标定值设定的对应开度区间,并根据区间上下限的扭矩值以及修正的油门踏板在对应区间所占的比例计算得到驾驶扭矩,最后对驾驶扭矩进行二次修正后得到轮端输出扭矩并输出,实现驾驶扭矩采集。本发明综合考虑温度、驾驶员操作以及整车故障的影响,得到的轮端需求扭矩更接近实际工况。
