Light beam control on a vehicle

摘要

The beam adjustment system automatically corrects the headlamp setting in dependence on the detected vehicle acceleration, or retardation, in the longitudinal direction. The vehicle has an anti-locking braking system or a drive slip regulation system (4), detecting the rotation of the vehicle wheels (2), from which the longitudinal acceleration, or retardation, is calculated, together with the corresponding variation in the spacing of the chassis from the ground. The analogue signal representing the latter is used to control the setting devices (5) for adjusting the beam angle of the headlamps (6).
