First Claim
Patent Images
1. A method for a subject vehicle driving on a road, the method comprising steps of:
- with a camera of the subject vehicle, capturing an image of a part of the road that has thereon an intangible symbol that is projected as light onto the part of the road by a road user other than the subject vehicle;
with a computing unit of the subject vehicle, detecting, in the image, the intangible symbol on the part of the road;
with the computing unit, identifying the intangible symbol detected in the image; and
with the computing unit, generating a signal based on the identified intangible symbol in order to bring about a measure in the subject vehicle in response to and dependent on the identified intangible symbol.

Abstract
A method and a camera-based driver assistance system in a subject vehicle uses image processing to automatically recognize dynamic intangible symbols that are projected as light onto the road by another vehicle, and responds in an appropriate manner based on the recognized symbols. For example, advice is given to the driver or signals are transmitted to vehicle devices in order to bring about an appropriate vehicle response, such as an emergency braking action or a distance alert.

12. A device for a subject vehicle driving on a road, the device including:
-
a camera configured and arranged to capture images of a part of the road, and a processor arrangement, wherein the camera is further configured and arranged to transmit the images captured by the camera to the processor arrangement, wherein the processor arrangement is configured and arranged to identify, in at least one of the images, an intangible symbol that is projected as light onto said part of the road by a road user other than the subject vehicle, and wherein the processor arrangement is further configured and arranged to generate a signal in order to bring about a measure in the subject vehicle in response to and dependent on the identified intangible symbol. - View Dependent Claims (13, 14)
