Lane detection system and method
First Claim
1. A lane detection system (20) for a vehicle, with a camera to record the lane markings (14, 18) in front of the vehicle, and an evaluation unit to evaluate the data sensed by the camera, characterized in that geometrical data of known types of lane markings are stored in the evaluation unit, that the evaluation unit identifies the type of the sensed lane markings by comparison with the stored lane markings, and that the evaluation unit determines the vehicle speed (v) from the identified geometrical data (Δ
- s) of the sensed lane markings and their temporal changes sensed by the camera (Δ
t).

Abstract
The disclosure relates to a lane detection system for a vehicle, having a camera for sensing the carriageway markings in front of the vehicle, and an evaluation unit for evaluating the data collected by the camera. Geometric data of known types of carriageway markings are stored in the evaluation unit, and the evaluation unit determines the type of sensed carriageway markings by comparing the sensed carriageway markings with the stored carriageway markings. The evaluation unit determines the velocity of the vehicle from the known geometric data of the sensed carriageway markings and their changes over time, which are sensed by the camera. The disclosure also relates to a method for operating a lane detection system.

10. A method to operate a lane detection system (2) for a vehicle, with which the lane markings (14, 18) in front of the vehicle may be sensed and evaluated, the vehicle speed (v) being determined as follows:
-
determination of the type of the sensed lane markings by comparison of the lane markings with stored types of lane markings, and determination of the vehicle speed from the known geometrical data of the sensed lane markings and their measured temporal changes. - View Dependent Claims (11)
