The invention discloses a torque control method for a transmission system of a pure electric vehicle, which has the design concept that in combination with the actual use characteristics of a pure electric vehicle, different working conditions with comprehensive coverage are set, and a relatively independent torque control strategy is formulated according to the characteristics of each working condition, so that the damage of torque impact to a transmission system is reduced, and therefore, all parts of the transmission system are protected. According to the method, additional structural components are not needed, a large amount of cost can be saved, and the method has better universality for the traditional system of the pure electric vehicle on the market.

    本发明公开了一种纯电动汽车传动系统扭矩控制方法,本发明的设计构思在于,结合纯电动汽车的实际使用特点,设定出覆盖全面的不同工况,并根据各个工况特点制定出相对独立的扭矩控制策略,以降低力矩冲击对传动系统的损坏,从而实现对传动系统各部件的保护。本发明无需额外增加结构部件,可以节省大量成本,对于市面上的纯电动汽车的传统系统而言,具有较佳的普适性。
