1. A method for controlling at least one member of a vehicle, comprising the following steps:
- obtaining navigation data suitable for characterizing a road context of the vehicle;
detecting target objects in front of the vehicle by using detection means onboard the vehicle;
determining a value of the relative distance between the vehicle and the target objects;
determining a state of traffic on the road used by the vehicle; and
controlling said at least one member by combining navigation data, a nature of the target objects, a relative distance values and said state of the traffic on said road used by the vehicle;
wherein based on relative speed between the vehicle and said target objects, characterizing a nature of said target objects as either moving vehicles or stationary obstacles;
in which the step for detecting target objects comprises;
measuring relative position and speed values between the vehicle and obstacles situated in front of the vehicle;
constructing target objects by (a) identifying objects lying a specified distance range from the vehicle, and grouping them into a first target object, and (b) identifying objects having a common relative speed range with respect to the vehicle, and grouping them into a second target object.

Abstract
A method and a system for controlling lighting beams for vehicles. It proposes controlling the road lighting beam by combining data obtained from a navigation device and detection means suitable for supplying distance and nature information concerning target objects situated in front of the vehicle equipped according to the invention.

19. A system for controlling at least one member of a vehicle comprising:
-
a navigation device for obtaining navigation data suitable for characterizing a road context of the vehicle; a detector for detecting target objects in front of the vehicle by using detection means onboard the vehicle; and a processor adapted to (1) determine a value of the relative distance between the vehicle and the target objects, (2) based on a relative speed between the vehicle and the target objects, characterize a nature of the target objects as either moving vehicles or stationary obstacles, wherein dividers between traffic lanes, posts, bus shelters, and traffic lights are characterized as stationary obstacles; and
(3) determine a state of traffic on the road used by the vehicle;said processor also controlling said at least one member by combining navigation data, said nature of the target objects, a relative distance values and said state of the traffic on said road used by the vehicle; wherein said detector; measures relative position and speed values between the vehicle and obstacles situated in front of the vehicle; constructs target objects by (a) identifying objects lying a specified distance range from the vehicle, and grouping them into a first target object, and (b) identifying objects having a common relative speed range with respect to the vehicle, and grouping them into a second target object. - View Dependent Claims (20, 21)
