The invention discloses an electric carrier and a motor braking parking method thereof. The state information of the electric carrier is analyzed when the electric carrier is parked on a flat ground and a slope, and heuristic rules of stable parking of the electric carrier are determined; and after it is determined that an electric carrier operator has a parking intention according to a signal fedback by an accelerator, a proper braking method can be selected according to the state information of the electric carrier in combination with the heuristic rules, the braking torque is adjusted in real time, and an electromagnetic band-type brake is controlled, so that the vehicle can be stably parked on the flat ground or the slope. In addition, the electric carrier disclosed by the invention comprises a motor driver, a motor, the electromagnetic band-type brake and the accelerator, wherein the motor not only provides driving force, but also provides braking force required by braking parking, the motor driver can realize seamless switching between a driving state and a braking state, and energy fed back during regenerative braking can charge the power battery, so that the endurance timeof the vehicle is prolonged.
