The invention provides a power system control method of a pure electric bus. The power system control method comprises the following steps: acquiring driving control information or braking control information; switching to a corresponding mode according to the value of the change rate of the driving or braking pedal, and outputting an opening curve of the driving or braking pedal in the corresponding mode to a corresponding torque control module; and according to the driving or braking pedal opening degree curve, a vehicle driving torque value or the target braking torque value is calculated, and a corresponding torque control instruction is output to a motor controller. By recognizing the driving intention of the change rate of the driving and braking pedals of the driver and switching different driving and braking modes in real time, the acceleration and torque control of the pure electric bus under different driving and braking working conditions is realized, the power requirements of the driver under various complex working conditions are met, the following performance and stability of the driving and braking torque are improved, and the driving safety of the pure electric bus is improved. And the dynamic property and the driving safety of the vehicle are more effectively ensured.

    本发明提供一种纯电动客车的动力系统控制方法,包括以下步骤:获取驱动控制信息或制动控制信息;根据驱动或制动踏板变化率的值,切换为对应模式,并输出对应模式下的驱动或制动踏板开度曲线给对应扭矩控制模块;通过所述驱动或制动踏板开度曲线,计算车辆驱动扭矩值或所述目标制动扭矩值,输出相应的扭矩控制指令给电机控制器。本发明通过对驾驶员驱动、制动踏板变化率快慢识别驾驶意图,实时切换不同的驱动、制动模式,实现纯电动客车在不同驱动、制动工况下的加速度及扭矩控制,满足驾驶员在各种复杂工况下的动力需求,提高驱动、制动扭矩的跟随性与稳定性,更有效地保证车辆动力性、与行车安全性。
