Pitch control of a headlamp

A headlamp levelling arrangement 1 considers both vehicle pitch and elevation of the headlamps above the road in order to maintain illumination of a constant distance in front of the vehicle. A vehicle posture detection system 2, preferably detecting the height of the chassis above the road (figure 2), measures the pitch of the vehicle. The control system 3 calculates an angular adjustment 3a for the pitch of the headlamps to compensate for the pitch of the vehicle. The control system then adds an angular correction 3b to compensate for deviation from a reference level of vehicle height, which also affects the range of the headlamps. This correction may be determined from the output of a height sensor at the front of the vehicle or it maybe determined from the acceleration of the vehicle as measured by a running state detection system 6.
