A hill start control method and a control device are provided. When a gas pedal is depressed, a creep torque is obtained according to a corresponding relationship between a drive motor rotate speed and the creep torque, and an output torque is obtained according to a corresponding relationship among a vehicle speed, an opening degree of the gas pedal, and the output torque. Comparing magnitudes of the creep torque and the output torque, and when the creep torque is greater than the output torque, the output torque is redetermined; the redetermined output torque is greater than or equal to the creep torque, and vehicle start is controlled via the redetermined output torque. When the creep torque is less than or equal to the output torque, the vehicle responds the output torque and controls the vehicle start via the output torque. Via this method, the output torque of the vehicle may always overcome hill resistance to prevent a risk of hill slip.
