Motor vehicle and method of operating a motor vehicle

A motor vehicle comprises a control device and a drive train having at least one electric traction motor, wherein the control device is adapted to activate at least one vibration element, which is coupled to at least one component of the motor vehicle and designed to put out a haptic signal which can be perceived by the driver of the motor vehicle, and/or the electric traction motor to generate at least one haptic signal in dependence on operating state information describing a current and/or predicted operating state of the drive train.

Claims preview

1 . A motor vehicle, comprising: a controller; a drive train having at least one wheel and at least one electric traction motor that, in operation, causes the at least one wheel to rotate; and at least one vibration element that is coupled to at least one component of the motor vehicle, wherein the controller, in operation, activates the at least one electric traction motor and the at least one vibration element to generate a plurality of haptic signals based on operating state information describing a current and/or predicted operating state of the drive train, wherein the controller, in operation, superimposes a torque output of the at least one electric traction motor with the haptic signals, wherein the haptic signals include at least a first haptic signal and a second haptic signal that is different from the first haptic signal, wherein the controller, in operation, superimposes the torque output of the at least one electric traction motor with the first haptic signal while the motor vehicle is accelerating, wherein the controller, in operation, superimposes the torque output of the at least one electric traction motor with the second haptic signal while the motor vehicle is braking, and wherein the second haptic signal simulates an anti-lock braking system. 2 . The motor vehicle according to claim 1 , wherein the at least one vibration element is arranged on a gas pedal, a brake pedal and/or a transmission control element, and/or the at least one vibration element is arranged on a driver's seat and/or on a vehicle structure. 3 . The motor vehicle according to claim 1 , wherein the at least one vibration element is arranged on a steering device of the motor vehicle, a gas pedal, a brake pedal and/or a transmission control element, and/or the at least one vibration element is arranged on a driver's seat and/or on a vehicle floor.
