Assembly for protecting a sensor/transmitter of a driver assistance system for a motor vehicle comprising a heating element

A protective assembly configured to protect a sensor/emitter of a driver assistance system of a motor vehicle, comprising:

• a protective device that surrounds a portion of the sensor/emitter, the protective device including:
• a first subassembly having a detection/emission element that submerges the sensor/emitter within the detection/emission element through which a signal passes, and
• a second subassembly having a motor configured to rotatably drive the first subassembly about an emission-reception axis of the sensor/emitter;
• where the first subassembly is arranged in front of the second subassembly;
• the protective assembly having at least one heating elements controlled by a control unit for heating at least one accessory fixed to a body of the motor vehicle next to the detection/emission element, the at least one heating element being disposed outside and at a distance from the protective device and adjacent the first subassembly.
