Abstract
A method for controlling an electric vehicle includes activating a drive force control strategy in response to a vehicle speed being below a speed limit and an angle of inclination of a road on which the electric vehicle is travelling being above a threshold angle. The method also includes determining a wheel slip of the at least one wheel when the drive force control strategy is active. The method further includes controlling an output torque of the at least one electric motor based on the determined wheel slip during an increase of the output torque to a requested value to facilitate a movement of the electric vehicle on the road. A torque coefficient used by the controller to control the output torque is selected based on at least one of a drive mode of the electric vehicle or the angle of inclination.
