Abstract: The invention relates to a motor vehicle assembly for protecting a sensor/transmitter of a driving assistance system comprising a protection device that partially surrounds the sensor/transmitter where the protection device includes a first subassembly (B) with a detection/transmission element positioned facing a sensor/transmitter's surface via which a signal passes, and a second subassembly (C) that includes a motor configured to rotatably drive the first subassembly (B) about a line of transmission/reception of the sensor/transmitter. According to the invention, the protection assembly includes at least one heating element controlled by a control unit that heats an accessory attached to the motor vehicle's body in the detection/transmission element's vicinity, the heating element being outside the protection device and in the vicinity of the first subassembly (B).

Abstract: Cleaning device for projecting a cleaning fluid toward a surface of an optical sensor, including a hollow body with an intake port for the cleaning fluid and an ejection nozzle for ejecting the cleaning fluid in the form of a jet, the hollow body being pierced with a conduit for distributing the cleaning fluid, and a deflection element arranged downstream of the ejection nozzle and configured to obstruct the jet of fluid ejected by the ejection nozzle in such a way as to modify the orientation of the jet of fluid with respect to the surface to be cleaned. The deflection element is adapted to move, depending on the pressure to which it is subjected by the jet of fluid, between a near position, in which the deflection element is next to the ejection nozzle, and a moved-away position, in which the deflection element is away from the ejection nozzle.

Abstract: A method of cancelling noise produced in a cabin of a vehicle by a wiper system. The method is implemented by a noise cancellation device and includes receiving feedforward data related to wiper noise. Such feedforward data can be issued from sensors collocated with elements of the wiper system, or from an ECU controlling motor operation of the wiper system. The method further includes generating a noise cancellation control signal based on the feedforward data and based on a model of propagation of the wiper noise in the cabin and transmitting the noise cancellation control signal to a speaker system of the vehicle.
