METHOD AND SYSTEM FOR AVOIDING PIXELS ERRORS IN HIGH-DEFINITION HEADLAMPS
A high-definition vehicular headlamp has a light module configured to produce a matrix of light-emitting points each of which has a coordinate pair. The headlamp generates a light image in front of the vehicle, and the light image is divided into a matrix of pixels that correspond respectively to the light-emitting points of the light module. A specified partial image content is generated in a partial region of the light image. The partial image content acts upon a set of coordinate pairs of light-emitting points, including coordinate pairs having defective light-emitting points that could cause pixel errors. A displacement vector is formed by comparing coordinate pairs of defective light-emitting points with the set of coordinate pairs of the light-emitting points on which the partial image content acts, and the partial image content is reproduced in the partial region of the light image that has been displaced by the displacement vector.
Vehicle light guidance system and method
A method of guiding a vehicle user approaching or exiting a vehicle. The method comprises projecting, by means of illumination from one or more light sources associated with the vehicle, a distinct illuminated path on the ground. The distinct illuminated path on the ground extends between the vehicle and a location remote from the vehicle. A light guidance system (10) for a vehicle (12), the system comprising one or more light sources (20, 22, 24, 26, 28, 30) associated with the vehicle and configured to project at least part of a distinct illuminated path (64) on the ground between the vehicle and a location remote from the vehicle.
