Exterior lighting system for a vehicle
An exterior lighting system for a vehicle comprising a lighting source configured to emit a light beam, the lighting source being part of one of existing exterior lights of the vehicle, an object being configured to have at least one active position and a passive position, the object being configured to modify the light beam in the at least one active position and to have no effect on the light beam in the passive position, an actuator configured to move the object between the at least one active position and the passive position, and a controller for controlling the actuator, the controller being configured to deactivate the actuator when the vehicle is not parked and activate the actuator only when the vehicle is parked.
1 . An exterior lighting system for a vehicle comprising:
a lighting source configured to emit a light beam, the lighting source being part of one of existing exterior lights of the vehicle;
an object being configured to have at least one active position and a passive position, the object being configured to modify the light beam in the at least one active position and to have no effect on the light beam in the passive position, the object being a deflector configured to deflect at least part of the light beam in the at least one active position;
a reflector configured to reflect the light beam after being deflected by the deflector;
an actuator configured to move the object between the at least one active position and the passive position; and
a controller for controlling the actuator, the controller being configured to:
deactivate the actuator when the vehicle is not parked, so as to prevent the actuator from moving the object, the object staying in the passive position; and
activate the actuator only when the vehicle is parked, so as to allow the actuator to move the object from the passive position to the at least one active position.
2 . The exterior lighting system of claim 1 , wherein in the at least one active position the object is placed on at least part of a path of the light beam and wherein in the passive position the object is placed away from the path of the light beam.
3 . The exterior lighting system of claim 1 , wherein the object is a diffusing panel, wherein the diffusing panel is configured to change at least one parameter of the light beam in the at least one active position, the at least one parameter being chosen in the group consisting of a color, an intensity, and a pattern.
4 . The exterior lighting system of claim 1 , wherein the controller is a Engine Control Unit (ECU) of the vehicle.
5 . The exterior lighting system of claim 1 , wherein the controller is configured to control the movement generated by the actuator to move the object, when the actuator is activated.
6 . The exterior lighting system of claim 1 , wherein the movement made by the object between the passive position and the at least one active position comprises at least one of a translation and a rotation.
7 . A vehicle comprising the exterior lighting system of claim 1 .
8 . A method for controlling the exterior lighting system of claim 1 , comprising:
checking if the vehicle is parked;
if the vehicle is parked, activating the actuator so as to allow the actuator to move the object from the passive position to the at least one active position; and
if the vehicle is not parked, deactivating the actuator, so as to prevent the actuator from moving the object, the object staying in the passive position.
9 . The method of claim 8 , wherein checking if the vehicle is parked comprises receiving information from at least one sensor or connected device about a state of the vehicle.
10 . The method of claim 9 , wherein the at least one sensor or connected device is chosen in a group consisting of a key fob, a dashboard dedicated switch, a front camera, a side camera, a front radar, a side radar, a smart phone app, a voice recognition and an exterior control panel.
11 . A computer system of a controller of the exterior lighting system of claim 1 , the computer system comprising processing circuitry configured to:
check if the vehicle is parked;
if the vehicle is parked, activate the actuator so as to allow the actuator to move the object from the passive position to the at least one active position; and
if the vehicle is not parked, deactivate the actuator so as to prevent the actuator from moving the object, the object staying in the passive position.
