First Claim
Patent Images
1. A method for resuming automatic mode of a headlamp control system, the method comprising the steps of:
- monitoring a headlamp state in the headlamp control system;
recommending a headlamp state from an automatic mode of the headlamp control system;
monitoring a driver input for a headlamp state to the headlamp control system;
causing a controller to temporarily change from the automatic mode to a manual mode when a driver inputs a headlamp state that conflicts with the recommendation from the automatic mode; and
causing the controller to return to an automatic mode when a recommendation for a headlamp state from the automatic mode matches the driver input for a headlamp state.

Abstract
A system and method for re-enabling automatic mode after manually overriding automatic mode of an automatic headlamp control system for a motor vehicle. The system and method monitors the headlamp state in a controller, recommends a headlamp state from the automatic mode of the automatic headlamp control system, monitors a driver request for headlamp state in the controller, and causes the controller to return to the automatic mode when the recommended headlamp state matches the driver request for a headlamp state.

2. The method as claimed in claim I wherein the controller operates the headlamp state as input by the driver and remains in the manual mode while the driver input for a headlamp state conflicts with the recommendation from the automatic mode.
-
3. The method as claimed in claim I wherein the headlamp state is a high beam state or a low beam state.

4. A system for switching between manual and automatic control of a vehicle headlamp system that controls a headlamp state of illumination, the system comprising:
-
a controller for controlling and monitoring a state of illumination of a vehicle headlamp system; a sensor coupled to the controller, the sensor for detecting illumination characteristics of a forward view of a vehicle headlamp system and providing an input to the controller, wherein the controller automatically controls a state of illumination for the vehicle headlamp system based on the sensor input; an input device coupled to the controller for inputting a state of illumination that manually overrides automatic control of the state of illumination; and the controller transitioning back to automatic control when the automatically controlled state of illumination matches the manually overridden input state of illumination. - View Dependent Claims (5, 6)
