The invention discloses a constant-speed cruise control method and system for an electric motor coach. The method comprises the steps of starting constant speed cruise; determining the cruising speed of the vehicle and the accelerator opening degree when the constant-speed cruising is started; collecting the current actual vehicle speed of the vehicle; determining the current motor power according to the current actual vehicle speed and the cruise vehicle speed; calculating a current motor request torque according to the current motor power; determining the current required torque of the motor according to the accelerator opening degree when the cruise control is started; and selecting the minimum value from the current motor request torque and the current motor demand torque to serve as the current control torque of the motor, controlling the motor, and constant-speed cruise is achieved. And the constant-speed cruise control of the electric motor coach is realized.

    本公开公开的一种电动客车定速巡航控制方法及系统,包括:开启定速巡航;确定车辆的巡航车速和定速巡航开启时的油门开度;采集车辆的当前实际车速;根据当前实际车速和巡航车速确定当前电机功率;根据当前电机功率计算当前电机请求扭矩;根据定速巡航开启时的油门开度,确定当前电机需求扭矩;从当前电机请求扭矩和当前电机需求扭矩中选取最小值,作为电机的当前控制扭矩,对电机进行控制,实现定速巡航。实现了对电动客车定速巡航的控制。
