Definitions
- TITLE Control system for at least one headlight of a motor vehicle.
- the technical field of the invention is the control of the lighting of motor vehicles, and more particularly the control of the adaptive lighting of the high beams of such vehicles.
- the Adaptive Lighting Function is a function that creates dark areas in the high beam located on cars located in front of the host vehicle so as not to dazzle them.
- This function is currently performed by three major components, a camera, a lighting computer dedicated to the function (“Light Control Unit”) and dedicated computers in each of the two projectors (“ADB driver LED” in English language).
- the purpose of the camera is to detect and locate the target vehicles on the road and transmits the position and width information of the target vehicles to the lighting computer.
- the lighting computer calculates the shadow zone to be produced on the road in order to envelop the target car and the angular portion without light of the high beam which must be produced by each of the headlamps.
- Each LED driver integrated into the headlights receives angular information and controls the activation or extinction of each of the high beam LEDs to create a dark zone on the target vehicle.
- An object of the invention is a control system for at least one headlight of a motor vehicle provided with at least one light-emitting diode, comprising at least one camera comprising calculation means capable of determining the presence of at least a vehicle to be detected in the scene in front of the motor vehicle and able to determine the shape of a shadow zone around at least one detected vehicle so that it is not blinded by the light emitted by the light emitting diode of the vehicle.
- headlight a headlight control means capable of controlling the state of each light-emitting diode as a function of the operating state of the headlight and of the shape of the shadow zone around the detected vehicle.
- the control means can receive information from the camera.
- the motor vehicle may include an electronic control means capable of transmitting the operating state of the headlight.
- the working state of the projector may include a high beam working state, a partial high beam working state and an off state.
- the ordering system has the advantage of reducing the number of ordering and processing means employed. Brief description of the drawings
- FIG. 1 illustrates a control system of. at least one headlight of a motor vehicle detailed description
- a control system 1 of lighting of a motor vehicle comprising a camera 2, at least one headlight 3 comprising at least one light-emitting diode LED, at least one control means 4 of the or each projector connected to an electronic control means.
- This control means is for example constituted by a control means of a host vehicle.
- the control means 4 of the projectors is connected to the projectors 3 via a control gateway.
- Camera 2 is provided with computing means and with a memory. These calculation means are constituted by hardware and software means embedded in a computer provided in the camera, the calculation means being duly programmed to detect by image processing the presence of a vehicle to be detected in a scene surrounding the host vehicle. .
- the camera 2 acquires images of the scene in front of the vehicle and the detection of vehicles present in the scene through its calculation means. Vehicles in the scene include vehicles being tracked and vehicles approaching. Camera 2 also determines the shadow zone to be produced around each vehicle detected to avoid dazzling by headlamps.
- This shadow zone constitutes an area of the scene in front of the host vehicle that should not be illuminated by the spotlights although it is within their range.
- the camera 2 transmits the shadow zones to be produced by control means 4 of the projectors which commands the LEDs to light them or to keep them lit according to the shadow zones to be produced received from the camera 2 and the operating mode of the headlamps 3 received from the electronic control means 5 of the vehicle.
- the control means 4 specifically transmits to each LED an activation or deactivation signal in order to configure and shape the lighting supplied by the projector to provide effective lighting while avoiding dazzling by generating zones of light. shadow in the lit scene.
