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).
