Abstract
An adaptive front-lighting system is provided for a vehicle, such as a passenger car, truck, or tractor trailer. A plurality of LED light sources on the vehicle have a projection pattern for exterior illumination to supplement a main beam from a main light source. A power supply drives the LED light sources according to a driving signal having a magnitude between a minimum driving signal and a maximum driving signal, wherein the LED light sources sequentially illuminate in response to the magnitude of the driving signal. A speed sensor characterizes an instantaneous vehicle speed. A turn sensor characterizes an instantaneous turning radius. A fuzzy controller generates the driving signal in response to the instantaneous vehicle speed and the instantaneous turning radius based on a fuzzy model. The fuzzy model is characterized by a plurality of empirically-derived fuzzy rules that define discontinuous values and by a plurality of modified consequents that produce a substantially continuous output.
