Abstract

A system comprising: one or more road-side illumination sources arranged to emit illumination to illuminate at least part of a road; one or more detectors arranged to detect a value of one or more parameters of a vehicle travelling on this road or this part of the road, the one or more parameters comprising a type of the vehicle and/or an identity of one or more users of the vehicle; and a controller arranged to control the illumination emitted by the one or more illumination sources, wherein the controller is configured to adapt the illumination in dependence on the detected value or values of the one or more detected parameters.

Claims

1. A system comprising:

one or more road-side illumination sources arranged to emit illumination to illuminate at least part of a road;

one or more detectors arranged to detect a value of one or more parameters of a vehicle travelling on said road, the one or more parameters comprising a type of the vehicle; and

a controller arranged to control the illumination emitted by the one or more illumination sources, wherein the controller is configured to adapt said illumination in dependence on the detected value or values of said one or more parameters,

wherein the one or more detected parameters comprise at least a detection of a control type of the vehicle, the value of the control type being detected from amongst a set comprising two or more of;

manually driven vehicle, assisted vehicle, and/or autonomous vehicle; and

wherein the controller is configured to apply one or more illumination settings designed for an artificial light or image sensor of the vehicle in case of detecting that the vehicle is an autonomous vehicle, and to apply one or more illumination settings designed for the human visual system in case of detecting that the vehicle is a manually controlled vehicle.

2. The system of claim 1, wherein the controller is configured to access a database mapping one or more respective illumination settings to each of a plurality of potential detected values for each of said one or more parameters or to each of a plurality of potential combinations of detected values of said parameters, and to perform said adaptation by looking up the one or more respective illumination settings mapped to the one or more detected values in the database and adapting the illumination accordingly.

3. The system of claim 2, wherein one or more of the illumination settings in said database are user preferences settable by one of one or more users of the vehicle.

4. The system of claim 1, wherein the one or more detected parameters comprise at least a body type of the vehicle, the value of the body type being detected from amongst a set comprising two or more of:

car, van, lorry, bus, motorcycle, and/or bicycle.

5. The system of claim 1, wherein the one or more parameters further comprises an attribute of one or more users of the vehicle, and wherein said attribute of the one or more users comprises an identity of one or more users of the vehicle.

6. The system of claim 5, wherein the detected parameters comprises both the type of the vehicle and the identity of the driver.

7. The system claim 5, wherein said attribute of the one or more users further comprises a user preference of the one or more users, being communicated from the vehicle to be detected by one of the one or more detectors.

8. The system of claim 1, wherein the controller is configured to adapt the illumination in further dependence on one or more motion-related variables of the vehicle.

9. The system of claim 8, wherein the motion-related variables comprise a position of the vehicle and/or a speed or velocity of the vehicle.

10. The system of claim 1, wherein the controller is configured to adapt the illumination in further dependence an environment of said road or said part of the road.

11. The system of claim 1, wherein:

the controller is configured to detect respective values of said one or more parameters for two or more different vehicles travelling on said road 4 or said part of the road and, for each of the two or more vehicles, to determine a respective one or more illumination settings for said illumination based on the value or values of the respective one or more settings; and

the controller is further configured to apply an arbitration process to arbitrate between the settings determined for the different vehicles, to thereby determine one or more illumination settings to apply to adapt said illumination.

12. A method comprising:

using one or more road-side illumination sources to emit illumination to illuminate at least part of a road;

detecting a value of one or more parameters of a vehicle travelling on said road or said part of the road, the one or more parameters comprising a type of the vehicle; and

controlling the illumination emitted by the one or more illumination sources, said control comprising adapting said illumination in dependence on the detected value or values of said one or more parameters,

wherein the one or more detected parameters comprise at least a detection of a control type of the vehicle, the value of the control type being detected from amongst a set comprising two or more of;

manually driven vehicle, assisted, and/or autonomous vehicle; and

wherein the controlling the illumination comprises applying one or more illumination settings designed for an artificial light or image sensor of the vehicle in case of detecting that the vehicle is an autonomous vehicle, and to apply one or more illumination settings designed for the human visual system in case of detecting that the vehicle is a manually controlled vehicle.

13. A computer program product for controlling one or more road-side illumination sources to emit illumination to illuminate at least part of a road, the computer program product comprising code embodied on a computer-readable storage medium and configured so as when run on a controller to perform operations of:

using one or more detectors to detect a value of one or more parameters of a vehicle travelling on said road or said part of the road, the one or more parameters comprising a type of the vehicle; and

controlling the illumination emitted by the one or more illumination sources, said control comprising adapting said illumination in dependence on the detected value or values of said one or more parameters,

wherein the one or more detected parameters comprise at least a detection of a control type of the vehicle, the value of the control type being detected from amongst a set comprising two or more of;

manually driven vehicle, assisted, and/or autonomous vehicle; and

wherein the controlling the illumination comprises applying one or more illumination settings designed for an artificial light or image sensor of the vehicle in case of detecting that the vehicle is an autonomous vehicle, and to apply one or more illumination settings designed for the human visual system in case of detecting that the vehicle is a manually controlled vehicle.
