Inside the interior housing space (3) there is at least one luminous module (4), an image acquisition element (5), a sensor element (6) and a cleaning element (7) configured to operate on the outer lens (2) of the image acquisition element (5). The housing (1) comprises a first auxiliary opening (8) covered by a detachable cap, wherein the sensor element (6) is able to be put through the first auxiliary opening. The outer lens (2) comprises a second auxiliary opening (25), wherein the image acquisition element (5) and/or the cleaning element (7) is able to be put through the second auxiliary opening (25) and secured on the housing (1).

This invention is related to an electronic substrate for an automotive lighting device. The electronic substrate comprises a a first side and a second side opposite to the first side, a power input (1), a communication bus input (2), at least a first layer (6) on the first side of the substrate (5), and a second layer (7) on the second side of the substrate (5); a first transceiver circuit having a first footprint (8) arranged on the first layer (6) and connected to the power input (1) and a second transceiver circuit having a second footprint (9) different from the first (8) being arranged on the second layer (7) and connected to the power input (1). One of the first transceiver (8) or the second transceiver (9) is connected to the communication bus input (2).

The present invention relates to a pivot assembly 400 for a wiper system 10. The pivot assembly 400 includes a connection assembly 410 to connect a wiper arm 200 to a pivot shaft 440 of the pivot assembly 400. The connection assembly 410 includes a through hole 422 provided on an arm head 420 and a knurled portion 442 formed on the pivot shaft 440 at predetermined location. The knurled portion 442 cooperates with the through hole 422 to form a torque transmitting joint between the arm head 420 and the pivot shaft 440. When an impact force more than a predefined force is applied on the arm head 420, the arm head 420 disengages from the knurled portion 442 to slide over the pivot shaft in downward direction, thereby absorbing the impact energy. The collapsible connection assembly 410 reduces injury to a pedestrian in case of collision.

The present invention relates to a connection assembly 200 for a wiper system 10. The connection assembly 200 includes a pivot shaft 105 rotatably mounted in a through bore 104d of a pivot housing 104, and an arm head 103 attached to the shaft 105. The arm head 103 includes a shaft-receiving portion 400 having a hub 400b to receive and secure the shaft 105. A retaining means 300 is provided to restrict relative movement between the shaft 105 and the housing 104. When an impact force more than a predefined threshold force is applied on the arm head 103, the retaining means 300 breaks/deforms allowing arm head 103 with the shaft 105 to collapse. When the arm head 103 is collapsed, at least a portion of the hub 400b is received in the through bore 104d. The collapsible connection assembly 200 reduces injury to pedestrian in case of collision.

The present invention relates to an arm head 103 for a wiper system 10. The arm head 103 may be attached to one end of a wiper arm 101. The arm head 103 includes a central hub portion 303 having a hole 301 to receive at least a portion of the pivot shaft 105 and a sidewall 203 provided around the central hub portion 303. One or more connection members 304 are formed between the central hub portion 303 and the sidewall 203. When an impact force more than a predefined force is applied on the arm head 103, the connection members 304 break and the sidewall 203 of the arm head 103 disengages from the central hub portion 303 to slide over the pivot shaft 105, thereby absorbing the impact energy. The collapsible connection assembly 200 reduces injury to a pedestrian in case of collision.

The invention provides method of controlling a lighting module to project a pixelated beam, the vehicle comprising a control module performing a glare free high beam function. The method comprises, for each border of a shadow tunnel positioned at an initial border position :- obtaining (602) a target border position for the border of the shadow tunnel;- controlling (605-607) the light source to move the border from the initial border position to the target border position.If an update direction is a tunnel reducing direction, controlling the light source comprises:- moving (606) the border to an intermediate border position being determined based on a current time period and on a current border speed that depends on a distance between a current border position and the target border position;- if the intermediate border position differs from the target border position, repeating (607) the previous step.
