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).
