Motor vehicle with driver assistance device and method for operating the motor vehicle

Abstract

The invention relates to a motor vehicle with a driver assistance device and to a method for operating the motor vehicle. The motor vehicle according to the invention has a driver assistance device which is designed to independently guide the motor vehicle while the motor vehicle is in motion, wherein the driver assistance device can be switched between a plurality of assistance modes. Furthermore, the motor vehicle has first, second and third operating devices ( 12 , 14 , 16 ), which differ from each other with respect to the operating processes to be carried out for their operation. In the driver assistance device at least one independent lateral guidance is provided in fully automatic assistance mode, at least one speed regulation is provided in semi-automatic assistance mode, and in manual assistance mode there is no control at all by the driver assistance device Describe the guidance of the car. Here, the first operating device (12) is then designed for direct guidance of the motor vehicle by the driver of the motor vehicle, and the second operating device (14) is designed for adjusting the driving parameters, the third operating device (16) is designed to operate a user interface for fully automatic assistance mode. A method for operating a motor vehicle that can be steered completely independently by means of a driver assistance device includes the step of controlling an actuator, whereby the rotational position of a steering wheel (12) of the motor vehicle is adjusted in dependence on the wheel steering angle currently set by the driver assistance device.

Description

technical field [0001] The invention relates to a motor vehicle which has a driver assistance device which is designed to independently guide the motor vehicle while it is in motion, the driver assistance device being able to operate at least Switching between two assistance modes differs from one another with regard to the degree of independence of the driver assistance device when guiding the motor vehicle. The guidance of the car is on the one hand the steering of the car (following the road change curve, orienting the car inside the lane, changing lanes), which is also called lateral guidance; the other is the control of the driving speed of the car (acceleration, braking, emergency braking, maintaining speed), this is also called longitudinal guidance. Also belonging to the invention is a method for operating a motor vehicle, by means of which the state of the motor vehicle is indicated to the driver. Background technique [0002] A driver assistance system of this ty...

Problems solved by technology

Such individual solutions are often limited to purely functional integration in existing operating elements, which leads to an increased functional density of the individual operating elements and is therefore not effective due to the resulting variety and complexity of the operating devices.
