Abstract

What is described is a motor vehicle having a sensor unit and a control device that is set up to steer the motor vehicle along an intended trajectory on the basis of data captured by the sensor unit. The control device has an evaluation device that is set up to take captured and/or received data as a basis for identifying a vehicle with a special task and/or a vehicle traveling in the wrong direction of travel and to take account of captured and/or received data that can be associated with the identified vehicle for ascertaining and/or steering along the intended trajectory. In addition, a method for autonomously controlling a motor vehicle is described. The method involves captured and/or received data being taken as a basis for identifying a vehicle with a special task and/or a vehicle traveling in the wrong direction of travel, and captured and/or received data that can be associated with the identified vehicle are taken into account for ascertaining and steering along an intended trajectory.

Claims

1. A motor vehicle having a sensor unit and a control device that is configured to steer the motor vehicle along an intended trajectory on the basis of data captured by the sensor unit, wherein the control device comprises an evaluation device that is configured to take captured and/or received data as a basis for identifying a vehicle with a special task and/or a vehicle traveling in the wrong direction of travel and to take account of captured and/or received data that can be associated with the identified vehicle for ascertaining and/or steering along the intended trajectory.

2. The motor vehicle as claimed in claim 1, wherein the sensor unit comprises at least one of an acoustic sensor unit, an optical sensor unit, a transmission/reception unit, a radar unit and an infrared unit.

3. The motor vehicle as claimed in claim 1, wherein the vehicle with a special task is one of a police vehicle, an ambulance, a fire-fighting vehicle, a vehicle of the federal border guard, a military vehicle, and a vehicle for a group of people charged with a public office.

4. The motor vehicle as claimed in claim 1, wherein the captured and/or received data are based at least on one of the following pieces of information:

a blue light,

an audible warning signal,

a piece of information transmitted by radio and/or mobile radio,

a piece of information from Car2x communication,

a piece of information transmitted by the identified vehicle, and

a piece of information transmitted by a control center.

5. The motor vehicle as claimed in claim 1, wherein the control device is configured to locate the identified vehicle on the basis of the captured and/or received data that can be associated with the identified vehicle.

6. The motor vehicle as claimed in claim 1, wherein the control device is configured to ascertain an intended trajectory, and to control the motor vehicle, such that the probable path of the identified vehicle is kept clear and a collision with the identified vehicle is avoided.

7. The motor vehicle as claimed in claim 1, wherein the control device is configured to match the speed of the motor vehicle to a hazard situation linked to the identified vehicle.

8. The motor vehicle as claimed in claim 1, wherein the control device is configured to take the captured and/or received data as a basis for locating a hazard spot and bypassing the hazard spot.

9. The motor vehicle as claimed in claim 1, wherein the control device is configured to modify the driving behavior of the motor vehicle at intersections and junctions on the basis of the captured and/or received data.

10. A method for autonomously controlling a motor vehicle, wherein captured and/or received data are taken as a basis for identifying a vehicle with a special task and/or a vehicle traveling in the wrong direction of travel, and captured and/or received data that can be associated with the identified vehicle are taken into account for ascertaining and steering along an intended trajectory.
