为了解决纯电动汽车动力性和操控性难以同时兼顾的问题，将驾驶员意图分为稳态意图和动态意图，稳态意图用于保证车辆的操控性，动态意图用于保证车辆的动力性，在此基础上提出了一种基于驾驶员意图识别的纯电动汽车动力性驱动控制策略，该策略首先分别采用“典型工作点+分段插值”和模糊推理方法来识别驾驶员的稳态和动态意图；接着采用“动态补偿转矩保持”和“动态补偿转矩归零”等算法计算动态补偿转矩；最后通过“增量式”动态补偿转矩跟踪算法和电机过载管理算法给出最终的转矩指令。仿真与试验结果表明，该策略既可以根据驾驶员稳态意图保证车辆的操控性，也可根据驾驶员动态意图提高车辆的动力性。%[ Abstract] In order to solve the problem of the difficulty in concurrently achieving good power performance and controllability of pure electric vehicles, the driver intentions are divided into steady-state intentions and dynamic intentions, which are used to ensure the controllability and power performance respectively. On this basis, a drive control strategy for the power performance of pure electric vehicles is proposed based on driver intention recognition. With this strategy, firstly the methods of “typical working point + piecewise interpolation“ and fuzzy reasoning are used to identify the steady-state and dynamic intentions of driver respectively. Then the maintenance and returning to zero algorithms for dynamic compensation torque are adopted to calculate dynamic compensation torque. Finally, the final torque instruction is given by using“incremental“ dynamic compensation torque tracking algorithm and mo-tor overload management algorithm. The results of simulation and test show that the strategy proposed can ensure the controllability of vehicle according to the steady-state intention of driver while enhancing the power performance of vehicle based on the dynamic intention of driver.
