The invention relates to an electric vehicle torque distribution method and system, and the method comprises the steps: firstly carrying out working condition construction and working condition recognition, taking a road condition recognition coefficient as a basis, suggesting a driving style and acceleration intention membership function, building a complete driving style and acceleration intention recognition model in combination with a fuzzy reasoning principle, and carrying out the recognition of a nearest working condition, therefore, the style of the driver is identified more accurately. On the premise of driving style recognition based on working conditions, the torque of a power system is reasonably distributed according to the torque requirement of the whole vehicle, the vehicle can work in an efficient area, and the economical efficiency is optimal.

    本发明涉及一种电动汽车转矩分配方法及系统,首先进行工况构建和工况识别,以路况识别系数为基础,建议驾驶风格和加速意图隶属度函数,再结合模糊推理原则,建立完整的驾驶风格和加速意图识别模型,对最近的工况进行识别,以此更加准确识别驾驶员的风格;在基于工况的驾驶风格识别的前提下,根据整车转矩需求,合理分配动力系统的转矩,能够使车辆工作在高效区域,使经济性达到最佳。
