Vehicle with optical scanning device for a lateral road area
First Claim
1. An optical scanning system for a vehicle, comprising:
- at least one laterally mounted optical scanning device for zero-contact scanning of a lateral highway area and for supplying optically sensed scanning data; and
an evaluation unit connected to the scanning device;
the optical scanning device comprises a linear array of infrared transmitting LEDs, as well as an associated CCD array, for scanning the surface of the highway to detect a lane boundary; and
wherein the evaluation unit comprises means for determining running time, contrast determination, and contour recognition from the data supplied by the scanning device.

Abstract
The invention provides a vehicle with a laterally mounted optical scanning device for zero-contact scanning of a lateral highway area and an evaluation unit connected thereto. The optical scanning device comprises a linear array of infrared transmitting devices located side by side and a corresponding CCD array, and the connected evaluation unit is programmed to perform time measurement, contrast measurement, and contour recognition. With this optical scanning system, a function to warn against falling asleep, an automatic lane maintenance function, a rear-area monitoring or environment monitoring function for the vehicle can be provided, with reaction to various types of lane boundaries being possible depending on the situation.
