Abstract
A method and an arrangement for light adaptation of the eyes of a driver of a vehicle when exiting a tunnel. The method and arrangement determines a tunnel exit position and changes a light source luminous flux of at least one light source in the vehicle as the vehicle approaches the tunnel exit position in response to the determination of the tunnel exit position.
Claims12
A method for light adaptation of the eyes of a driver of a vehicle when exiting a tunnel, wherein the method comprises:
- determining a tunnel exit position, and
- changing a light source luminous flux of at least one light source in the vehicle as the vehicle approaches the tunnel exit position in response to the determination of the tunnel exit position;
- upon determining the tunnel exit position:
- determining a tunnel exit time for the vehicle to reach the tunnel exit position, and
- determining a light adaptation time,
- if the tunnel exit time is equal to or shorter than the light adaptation time,
- changing the light source luminous flux of the at least one light source in the vehicle as the vehicle approaches the tunnel exit position during the tunnel exit time, and
- wherein the at least one light source is configured to emit light of various colors and/or emit light of various color temperatures, the method further comprises:
- determining at least one of a color or a color temperature of light at the tunnel exit position,
- matching a color and/or a color temperature of light emitted by the at least one light source in the vehicle to the determined at least one of color or color temperature of light at the tunnel exit position.
7 more elements
A light adaptation arrangement for a vehicle, wherein the arrangement comprises;
- at least one light source arranged in the vehicle and configured to emit light of various colors and/or emit light of various color temperatures;
- and
- an electronic control unit arranged in the vehicle and connected to control the at least one light source,
- wherein the electronic control unit is configured to determine tunnel exit position, and for changing a light source luminous flux of at least one light source in the vehicle as the vehicle approaches the tunnel exit position in response to the determination of the tunnel exit position;
- wherein the electronic control unit is configured to determine tunnel exit time for the vehicle to reach the tunnel exit position upon determining the tunnel exit position, and for determining a light adaptation time and, if the tunnel exit time is equal to or shorter than the light adaptation time, for changing the light source luminous flux of the at least one light source in the vehicle as the vehicle approaches the tunnel exit position during the tunnel exit time;
- and
- wherein the electronic control unit is configured to determine at least one of a color or a color temperature of light at the tunnel exit position and control a color and/or a color temperature of light emitted by the at least one light source in the vehicle to match the determined at least one of light color or color temperature of light at the tunnel exit position.
