    Abstract: A method and apparatus for controlling a motor of an electric vehicle. A current acceleration a of the motor is calculated in real time according to detected rotor position values. If the current acceleration a is greater than a predetermined forward acceleration a 0, then the motor output torque is decreased. If the acceleration a is less than a predetermined backward acceleration a 1, then the motor output torque is increased. Thus, when the vehicle travels from a normal road surface to a slippy road surface or on the contrary, decreasing or increasing the motor output torque may suppress an abrupt variation of vehicle speed. According to a preferred embodiment, reducing output torque during early period may suppress current abrupt variation, protect the power device, and avoid the vehicle being out-of-control caused by a rotor blocking or a motor skidding.

    Abstract translation: 一种用于控制电动车辆的电动机的方法和装置。 根据检测到的转子位置值，实时计算电机的当前加速度a。 如果当前加速度a大于预定的正向加速度a0，则电动机输出转矩减小。 如果加速度a小于预定的后退加速度a1，则电动机输出转矩增加。 因此，当车辆从正常路面行驶到路面滑坡时，或者相反地，减小或增加电动机输出转矩可以抑制车速的突然变化。 根据优选实施例，在早期期间减小输出转矩可以抑制电流突然变化，保护动力装置，并且避免车辆由转子阻塞或电动机打滑导致​​失控。
