Motor vehicle adaptive front headlight system in which the straight-ahead position of the vehicle is reliably detected based on the signals from a steering angle sensor and additionally left and right wheel velocity sensors

摘要

Headlamp arrangement for a vehicle that has a steering system coupled to a steering wheel. A control arrangement is used to control the light output from a headlamp based on the steering angle of the steering system. The control arrangement is configured to determine the position of the steering system based on a start position signal, which is given by the steering system for each rotation of the steering wheel and based on left and right wheel speeds. Independent claims are also included for the following:- (a) a vehicle headlamp arrangement and; (b) a method for controlling the light output and distribution of a headlamp based on comparison of wheel velocities with reference values.
