Abstract:

A system for self-aligning a headlamp of a vehicle, the system comprises at least one actuator which modifies an alignment of the headlamp in response to a control signal. An infrared light source is mounted to the headlamp to emit an infrared light beam toward a ground surface. An optical sensor system is oriented to sense a reflection of the infrared light beam from the ground surface. The optical sensor system has a plurality of optical sensors to sense a plurality of infrared light intensities from the reflection. A control circuit is operatively responsive to the optical sensor system to form the control signal for the at least one actuator. The control signal acts to modify the alignment of the headlamp so that the infrared light intensities satisfy at least one predetermined condition consistent with a desired alignment of the headlamp to thereby automatically align the headlamp to the desired alignment.
