Patent ID: 8538629

Claim:
A device for assisting a driver in steering a vehicle along a bottleneck, including a roadwork site, the device comprising: a bottleneck detection unit configured to detect bottleneck information for characterizing the bottleneck in which the vehicle is disposed; a bottleneck information processing unit connected to said bottleneck detection unit for processing the bottleneck information detected to derive therefrom assistance information for assisting the driver in steering the vehicle along the bottleneck; and an actuation unit for actuating a light source of the vehicle such that the light source generates a light pattern, which can be seen by the driver, outside the vehicle, the light pattern displaying the assistance information to the driver, said actuation unit connected to said bottleneck information processing unit; said actuation unit configured to actuate the light source of the vehicle such that the light source: generates the light pattern with a visual code which indicates to the driver a current distance of the vehicle from a roadway edge or from a roadway boundary barrier which delimits a roadway, and generates the visual code as a spatially spaced-apart pair of light structures, where a distance between the spatially spaced-apart pair of light structures is proportional to the current distance of the vehicle from the roadway edge or from the roadway boundary barrier which delimits a roadway.
