Predictive adaptive front lighting algorithm for branching road geometry
First Claim
1. A system for adaptive front lighting of a vehicle, the system comprising:
- a first headlamp and a second headlamp configured to cooperatively project a beam pattern;
a first swivel mechanism coupled to the first headlamp to change a swivel angle of the first headlamp;
a second swivel mechanism coupled to the second headlamp to change a swivel angle of the second headlamp; and
a controller configured to determine a most likely path of the vehicle and a secondary path, wherein the controller is configured to calculate a first desired swivel angle of the first headlamp based on the most likely path of the vehicle and a second desired swivel angle of the second headlamp based on the secondary path of the vehicle.

Abstract
A system for predictive front lighting of a vehicle. The system includes at least two headlamps, at least two swivel mechanisms and a controller. The first and second headlamps project a beam pattern for illumination of the vehicle path. The controller receives vehicle position data, as well as, data regarding a most likely path and a secondary path of the vehicle. The controller then calculates the desired swivel angle of the headlamps based on the most likely path of the vehicle and the secondary path of the vehicle, and the swivel mechanisms respectively manipulate each of the headlamps to accordingly change alignment of the headlamps based on the swivel angle for each of the of the headlamps.
