Abstract

The present disclosure relates to a method for operating an assistance system of a motor vehicle, wherein the assistance system has a projector. A message relating to a wrong-way driver is received, and a position of the wrong-way driver transmitted with the message is compared with a current position. Depending on the comparison, a recommendation for adapting a driving parameter is projected into an area in front of the motor vehicle for the driver by means of the projector. The present disclosure also relates to an assistance system of a motor vehicle and to a motor vehicle.

First claim

The invention claimed is:

1. A method for operating an assistance system of a motor vehicle, wherein the assistance system has a projector, the method comprising:
receiving a message relating to a wrong-way driver;
comparing a position of the wrong-way driver transmitted with the message to a current position of the motor vehicle, wherein the current position is a current location of the motor vehicle;
providing, depending on the comparison, a recommendation for adapting a driving parameter projected into an area in front of the motor vehicle for a driver of the motor vehicle by means of the projector;
detecting a reaction of the driver of the motor vehicle; and
outputting a warning if the reaction does not correspond to the recommendation.

2. The method according to claim 1 , wherein the driving parameter comprises a speed.

3. The method according to claim 1 , wherein the driving parameter comprises a lane.

4. The method according to claim 1 , wherein a further road user is detected and the recommendation is created based on the detection.

5. The method according to claim 4 , wherein the driving parameter comprises a distance from the other road user.

6. The method according to claim 1 , wherein the recommendation is based on a driving maneuver.

7. An assistance system of a motor vehicle, wherein the assistance system comprises:
a projector;
a first unit for detecting a current position of the motor vehicle or a first interface for coupling to the first unit for signal exchange;
a second unit for detecting a message relating to a wrong-way driver or a second interface to the second unit; and
a control unit configured to:
receive the message;
compare a position of the wrong-way driver transmitted with the message to the current position, wherein the current position is a current location of the motor vehicle;
provide, depending on the comparison, a recommendation for adapting a driving parameter projected into an area in front of the motor vehicle for a driver of the motor vehicle by means of the projector;
detect a reaction of the driver of the motor vehicle; and
output a warning if the reaction does not correspond to the recommendation.

8. A motor vehicle having an assistance system wherein the assistance system comprises:
a projector; a first unit for detecting a current position of the motor vehicle or a first interface for coupling to the first unit for signal exchange; a second unit for detecting a message relating to a wrong-way driver or a second interface to the second unit; and
a control unit configured to:
receive the message;
compare a position of the wrong-way driver transmitted with the message to the current position, wherein the current position is a current location of the motor vehicle;
provide, depending on the comparison, a recommendation for adapting a driving parameter projected into an area in front of the motor vehicle for a driver of the motor vehicle by means of the projector;
detect a reaction of the driver of the motor vehicle; and
output a warning if the reaction does not correspond to the recommendation.
