Patent number: 8738236Abstract: A method and system for adjustment of headlamps for motor vehicles, comprising a step for calculating a headlamp angle. The method furthermore comprises the steps of detecting a target vehicle, calculating a lateral position of the target vehicle with respect to the motor vehicle, calculating a lateral angular offset with respect to the said lateral position of the target vehicle and adjusting the headlamps as a function of the headlamp angle and of the lateral angular offset.Type: GrantFiled: November 18, 2011Date of Patent: May 27, 2014Assignee: Valeo VisionInventors: Julien Moizard, Gregoire Sadoux, Jonathan Blandin

Patent number: 8659659Abstract: A system and process of gauging a camera suitable for equipping a vehicle. The system and process determines at least one value of at least one geometrical parameter of the camera, at least in accordance with an item of information that represents a parameter associated with an object detected by the camera, compares the determined value to a value of reference (?pitching_ref, ?rolling_ref, ?twisting_ref) of the geometrical parameter of the camera, and controls the geometrical parameter of the camera in accordance with the comparison, particularly by modifying the value of reference in such a way as to gauge the camera.Type: GrantFiled: October 28, 2010Date of Patent: February 25, 2014Assignee: Valeo VisionInventors: Benazouz Bradai, Julien Moizard, Julien Rebut

Patent number: 8465184Abstract: An automatic headlight switching procedure for motor vehicles, designed to emit a beam of light from one lighting mode to another lighting mode. The process features the steps of when the headlights are in a first lighting mode, detecting the backscatter of the headlight beam onto a phenomenon of visibility disturbance; increasing the lighting range of the headlight beam in relation to a maximum authorized range in accordance with the detected backscatter; and switching the headlights to a second lighting mode when the backscatter is below a first determined threshold.Type: GrantFiled: December 17, 2009Date of Patent: June 18, 2013Assignee: Valeo VisionInventors: David Hue, Julien Moizard, Patrice Reilhac

Publication number: 20120221230Abstract: The invention relates to a method for generating and supplying traffic-relevant information, wherein each of a plurality of road users (10.1, 10.2) is provided with a mobile communications unit with which individual movement data (10.5) is wirelessly transmitted to a central processing system (20). The individual movement data (10.5) of the plurality of road users (10.1, 10.2) is collected and processed to location-specific and/or route-specific traffic-relevant information (30.1, 30.2), which relates to individual route sections or a road network (5). Upon request (10.7), the location-specific and/or route-specific traffic-relevant information (30.1, 30.2) is transmitted from the central processing system (20) to the mobile communications units. In order to increase and improve the information content of the traffic-relevant information that has been generated and supplied, the individual movement data (10.Type: ApplicationFiled: October 27, 2010Publication date: August 30, 2012Applicant: VALEO SCHALTER UND SENSOREN GMBHInventors: Patrice Reilhac, Adrien Charpentier, Julien Moizard, Siav-Kuong Kuoch, Patrick Bonhoure, Lowik Chanussot

Patent number: 7708434Abstract: A proposed method to illuminate optimally, or at least in an improved fashion compared with existing solutions, a road taken by a vehicle in question implementing the method whilst ensuring that other vehicles are not dazzled. To this end, it is not proposed in the invention to detect the distance between the vehicle in question and the first vehicle liable to be dazzled by the vehicle in question, and to generate accordingly a light beam optimized in terms of range on the road, and advantageously light intensity; according to the invention, the optimization of the light beam produced is achieved by the use of the motorway function available on the vehicle in question. The use of this function in this context also ensures a gradual transition between the function of the dipped type and the function of the main-beam type in the context of automatic switching operations between these functions.Type: GrantFiled: November 16, 2007Date of Patent: May 4, 2010Assignee: Valeo VisionInventors: Julien Moizard, Benoît Reiss, Pierre Albou, David Bourdin

Patent number: 6926430Abstract: In the invention, a comparison is carried out within a computer of an item of information relating to a direction of a light beam of a lamp, this item of information being obtained by means of a position sensor, and an item of information relating to an instruction for horizontal displacement of the light beam. If there is not agreement between the two items of information, the computer can then have a degraded operating mode of the lamp adopted by compelling it to orient the light beam downwards in order to remove any risk of dazzling an oncoming driver. To that end, the computer controls a range correction motor in order to bring about a downwards vertical deviation of the light beam.Type: GrantFiled: May 27, 2003Date of Patent: August 9, 2005Assignee: Valeo VisionInventors: Alain Dari, Grégoire Sadoux, Julien Moizard
