Abstract
An adaptive lighting system of an off-road utility vehicle includes an illumination device controllable with respect to its emission characteristic or light intensity, and a control unit in communication with the illumination device. The control unit is configured to adapt the emission characteristic or light intensity level by controlling the illumination device based upon a determined gaze direction of a vehicle operator, an identified extraneous light effects, a determined relative position of an external off-road utility vehicle, or cartographic location information.
Claims17
An adaptive lighting system of an off-road utility vehicle, comprising:
- an illumination device controllable with respect to its emission characteristic or light intensity;
- and
- a control unit in communication with the illumination device;
- wherein, the control unit is configured to adapt the emission characteristic or light intensity level by controlling the illumination device based upon a determined gaze direction of a vehicle operator, an identified extraneous light effects, a determined relative position of an external off-road utility vehicle, or cartographic location information;
- and
- wherein the control unit is configured to reduce the light intensity in areas external to the off-road utility vehicle on a side or rear of the off-road utility vehicle which are outside of the viewing direction and increase the light intensity in areas external to the off-road utility vehicle on a side rear of the off-road utility vehicle which are within the viewing direction by adjusting the light intensity or the emission characteristic of the illumination device.
An off-road utility vehicle, comprising:
- an operator's cab including controls for controlling the vehicle;
- an adaptive lighting system comprising an illumination device controllable with respect to its emission characteristic or light intensity;
- and
- a control unit in communication with the illumination device;
- wherein, the control unit is configured to adapt the emission characteristic or light intensity level by controlling the illumination device based upon a determined gaze direction of a vehicle operator, an identified extraneous light effects, a determined relative position of an external off-road utility vehicle, or cartographic location information;
- wherein the control unit is configured to extend illumination towards a portion of the external off-road utility vehicle and reduce the illumination towards an operator of the external off-road utility vehicle by adjusting the light intensity or the emission characteristic of the illumination device;
- and
- wherein the control unit is configured to reduce the light intensity in areas external to the off-road utility vehicle on a side or rear of the off-road utility vehicle which are outside of the viewing direction and increase the light intensity in areas external to the off-road utility vehicle on a side or rear od the off-road utility vehicle which are within the viewing direction by adjusting the light intensity or the emission characteristic of the illumination device.
