IPC: B60K35/00
Abstract: A system for controlling a brightness of a graphics projector for a vehicle includes a vehicle sensor, the graphics projector including at least one light source module, and a controller in electrical communication with the vehicle sensor and the graphics projector. The controller is programmed to determine an ambient light level using the vehicle sensor. The controller is further programmed to determine a projector brightness offset value based at least in part on the ambient light level. The controller is further programmed to project a graphic using the graphics projector based at least in part on the projector brightness offset value.
