Abstract: An electrical architecture includes multiple nodal controllers, at least two power sources, and a power supply network. Each nodal controller includes at least one output port configured to be connected to an electrical load operating with a voltage of multiple different voltages. The at least two power sources are associated with the multiple different voltages and configured to supply the multiple nodal controllers through the power supply network. The power supply network includes a power line connecting the multiple nodal controllers to each other in a ring and is configured to supply the multiple nodal controllers with electrical power from the at least two power sources. Each nodal controller of the multiple nodal controllers is linked to the power line via a bidirectional DC/DC converter and is configured to control a sleep or a wake-up mode responsive to detection of a corresponding voltage transition within the power supply network.

Abstract: A method for detecting non-visible vehicles in a vehicle's environment includes screening, by a receiver of a proximity sensor, any incoming proximity signal capable of propagating through the air along a non-linear path. Receiving such an incoming proximity signal and processing the received proximity signal allows for detecting an object that is otherwise not visible to a driver or another type of sensor on a vehicle and warning the driver or an advanced driver-assistance system about the detected object.

Abstract: A vision system for a motor vehicle includes an optical image capture device configured to capture images of objects in its field of vision. A lighting device includes a plurality of lighting elements forming a lighting matrix configured to illuminate the field of vision of the optical device. A control device associated with the optical device and the lighting device is configured to determine the nature of each image of an object captured by the optical device. The control device is configured to locate the object, select the lighting elements of the lighting matrix capable of illuminating the object relative to the location of the object, and individually control at least one lighting characteristic of each selected lighting element so as to be able to determine the nature of the image of the object captured by the optical device.

Abstract: A method for detecting non-visible vehicles in a vehicle's environment, wherein each vehicle is equipped with at least one proximity sensor, the method comprising for a driven vehicle the steps of: screening, by a receiver of the proximity sensor, any incoming proximity signal capable of propagating through the air along a non-linear path; Receiving an incoming proximity signal coming from a non-visible vehicle (B); processing the received proximity signal to detect the non-visible vehicle; and warning a driver and/or an advanced driver-assistance system about the detected non-visible vehicle.
