Abstract

A system and method for dynamically recalibrating an adaptive lighting system includes a control module configured to instruct a motor to rotate a lamp to a first hard stop when the lamp positioned at a first soft stop. The system recalibrates the control module using the first hard stop as a reference point.

Claims (11)

1. A system for dynamically recalibrating an adaptive lighting system, the system comprising:

a lamp pivotably mounted to a frame, wherein the lamp is configured to rotate about a central axis between a first hard stop and a second hard stop, a center line being located between a first hard stop and a second hard stop, a center line being located between the first and second hard stop;

a stepper motor coupled to the lamp, the motor configured to rotate the lamp between the first hard stop and the second hard stop; and

a control module in electrical communication with the motor, wherein the control module is configured to instruct the motor to rotate the lamp between a first soft stop and a second soft stop, the first soft stop being located between the first hard stop and the center line and the second soft stop being located between the second hard stop and the center line; and

wherein the control module is further configured to instruct the motor to rotate the lamp to the first hard stop when the lamp positioned at the first soft stop and to recalibrate the control module using the first hard stop as a reference point; wherein the lamp is a headlamp for an automobile.

2. The system of claim 1 , wherein the first hard stop is about 18 degrees from the center line.

3. The system of claim 1 , wherein the first soft stop is about 15 degrees from the center line.

4. The system of claim 1 , wherein the control module is further configured to instruct the motor to rotate the lamp to the second hard stop when the lamp positioned at the second soft stop and to recalibrate the control module using the second hard stop as the reference point.

5. The system of claim 4 , wherein the second hard stop is about 18 degrees from the center line.

6. The system of claim 4 , wherein the second soft stop is about 15 degrees from the center line.

7. The system of claim 1 , wherein the control module is configured to instruct the motor to rotate the lamp to a position corresponding to a steering angle position of the automobile.
