Head-up display and method with speed sensitive light intensity
First Claim
1. A method of controlling a light intensity output of a head-up display for a vehicle comprising:
- providing a controller;
providing ambient light intensity data from a light sensor to the controller;
providing vehicle speed data from a speed sensor to the controller; and
adjusting the light intensity output of the head-up display based on both the ambient light intensity data and the vehicle speed data using the controller.

Abstract
A head-up display light source intensity control for a vehicle can include sensing an ambient light intensity condition and providing ambient light intensity data indicative of the ambient light intensity condition to a controller. A speed of the vehicle is sensed and vehicle speed data indicative of the speed of the vehicle is provided to the controller. The controller is configured to calculate a light intensity output value for the head-up display based on both the ambient light intensity data and the vehicle speed data. The light intensity output of a light source of the head-up display is adjusted based upon the light intensity output value.
