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.

An FCV includes: a driving device that generates traveling power by using at least one of FC energy and battery energy; and a display device that presents an indicator indicating the traveling power that is being generated by the driving device. When the traveling power is less than a threshold value, the driving device generates the traveling power by using one energy of the FC energy and the battery energy without using the other energy of the FC energy and the battery energy. When the traveling power is more than or equal to the threshold value, the driving device generates the traveling power by using both the FC energy and the battery energy. At the indicator, the display device presents information indicating the threshold value.

Anti-jerk method

When there is a history that a required torque has reached a high torque range and the required torque falls within a low torque range, a start threshold is changed from a value larger than a maximum double-drive torque to a value smaller than a selection threshold for selecting a single-drive mode or a double-drive mode. When the required torque becomes larger than the start threshold, an engine is started.
