    at least one operating element by which the transverse guide controller and the longitudinal guide controller are selectively activated;

    a steering sensor which detects an operation of the steering wheel of the vehicle by the driver, wherein the transverse guide controller is deactivated by a signal of the steering sensor, without the longitudinal guide controller being deactivated; and

    a brake pedal sensor which detects an operation of the brake pedal of the vehicle, wherein the transverse guide controller and the longitudinal guide controller are deactivated by a signal of the brake pedal sensor;

    wherein there is an activation hierarchy for the longitudinal guide controller and the transverse guide controller, according to which the transverse guide controller is activatable only in common with or in addition to the longitudinal guide controller, and according to which the longitudinal guide controller, when the transverse guide controller is activated, is deactivatable in going along with a deactivation of the transverse guide controller, by an operation of the brake pedal or by a movement of the steering wheel.
