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.
