Vehicle having an apparatus for headlamp levelling and an anti-theft alarm system

The invention relates to a vehicle having an apparatus 1 for the headlamp levelling of at least one headlamp of a vehicle, wherein the apparatus 1 has at least one inclination sensor 2. In addition, the vehicle has an anti-theft alarm system 3. The at least one inclination sensor 2 is connected to the anti-theft alarm system 3.

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.

The front and rear axles of the vehicle are fitted with pneumatic/hydraulic monitors to sense the axle loading, and these monitors are coupled to slave servos in the headlamp tilting control to adjust the headlamp inclination to compensate for axle loading. To provide a failsafe system, which ensures that the headlamps do not swing up to dazzle oncoming traffic, if one or both servos fail, the salve cylinder on each headlamp has two pistons linked by a spring and with the first piston linked to the tilt control by a spring linkage. The output of the two axle servos are introduced on opposite sides of the second piston, so that their total effective force, being the difference in the outputs, pushes against the sprung linkage to lift the headlamps.
