A vehicle includes a drive unit configured to generate a drive torque in driving relationship to wheels of the vehicle, and a gas pedal constructed in the form of an active accelerator pedal which is adjustable over a pedal travel. A control device activates the drive unit in response to a desired torque given by a driver through actuation of the accelerator pedal. Operatively connected to the control device is an actuator which applies a resistance force upon the accelerator pedal, thereby generating a pressure point for the accelerator pedal, with the resistance force increasing in a locally limited pedal travel interval up to a maximum force which can be overridden by the driver. An evaluation unit of the control unit generates a deactivation signal within the pedal travel interval, when the accelerator pedal reaches a predefined limit hold time.
