Abstract

A system for predictive front lighting of a vehicle. The system includes a first and second headlamps, a first and second 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, for example from a GPS system, and accesses a map database to identify a map location of the vehicle. The controller further analyzes the map to determine a most likely path of the vehicle based on the map location and other vehicle heading parameters. The controller then calculates the desired swivel angle of the first and second headlamps based on the most likely path of the vehicle, and the first and second swivel mechanisms manipulate the first and second headlamps to accordingly change the swivel angle of the headlamps.
