Motor vehicle having a driver assistance device and method for operating a motor vehicle

Abstract

The invention relates to a motor vehicle having a driver assistance device and to a method for operating a motor vehicle. The motor vehicle according to the invention has a driver assistance device which is designed to guide the motor vehicle in an automated manner during travel and which can be switched between a plurality of assistance modes. The motor vehicle further comprises a first, a second and a third control device (12, 14, 16), which differ in the control actions to be carried out for their operation. In the driver assistance device, at least one independent lateral guidance is provided in a fully automated assistance mode, at least one speed control is provided in a partially automated assistance mode and no guidance of the motor vehicle is provided by the driver assistance device in a manual assistance mode. The first operating device (12) is designed to directly drive the motor vehicle by a driver of the motor vehicle, the second operating device (14) is designed to adjust the driving parameters for the partially automated assistance mode, and the third operating device (16) is designed to operate a user interface for the fully automated assistance mode. The method for operating a motor vehicle, which can be guided in a fully automated manner by means of a driver assistance device, thus comprises the step of activating an actuator by which a rotary position of a steering wheel (12) is adjusted as a function of a 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.
