Automatic directional control system for vehicle headlights
First Claim
1. An automatic directional control system for a vehicle headlight comprising:
- a sensor that is adapted to generate a signal that is representative of a condition of the vehicle;
a controller that is responsive to said sensor signal for generating an output signal, said controller including a table that relates values of said sensor signal to values of said output signal, said controller being responsive to said sensor signal for looking up said output signal in said table; and
an actuator that is adapted to be connected to the headlight to effect movement thereof in accordance with said output signal.

Abstract
A structure and method for operating a directional control system for vehicle headlights that is capable of altering the directional aiming angles of the headlights to account for changes in the operating conditions of the vehicle. One or more operating condition sensors may be provided that generate signals that are representative of a condition of the vehicle, such as road speed, steering angle, pitch, suspension height, rate of change of road speed, rate of change of steering angle, rate of change of pitch, and rate of change of suspension height of the vehicle. A controller is responsive to the sensor signal for generating an output signal. An actuator is adapted to be connected to the headlight to effect movement thereof in accordance with the output signal. The controller can include a table that relates values of sensed operating condition to values of the output signal. The controller is responsive to the sensor signal for looking up the output signal in the table.
