The invention provides a new energy automobile driving method. A mode of adjusting motor driving torque is adopted, after the slip rate exceeds an optimal slip rate control interval, a classic PI control mode is adopted, the slip rate is made to return to the optimal slip rate control range, and when the slip rate is located in the optimal interval, the required torque of a whole automobile, namely an accelerator pedal of a driver, is directly output. The real-time, continuous and automatic adjustment of the slip rate is realized; compared with a traditional ESP (Electronic Stability Program)system, under the condition that the hardware cost is not increased, starting and driving torque output of the whole automobile on a wet and slippery road surface can be improved, the adjusting precision is improved, abrasion of a brake pad is reduced, and automobile torque fluctuation and automobile body shaking caused when the driving anti-skid function plays a role are further avoided.
本发明提供了一种新能源汽车驱动方法，采用调节电机驱动扭矩的方式，在滑移率超出最优滑移率控制区间后，采用经典的PI控制方式，使所述滑移率回归至最优滑移率控制范围，当所述滑移率处在最优区间时，直接输出整车即驾驶员油门踏板的需求扭矩。实现了所述滑移率的实时、连续、自动调节，相较于传统ESP(Electronic Stability Program)系统，能够在不增加硬件成本的情况下，改善整车在湿滑路面上的启动、驱动扭矩输出，提升调节精度，减小了刹车片的磨损，也进一步避免了驱动防滑功能起作用时所引起的车辆扭矩波动与车身抖动。
