DescriptionThis device allows maximum ease of manoeuvring during parking; with reverse gear engaged, it indicates if the driver is approaching an obstacle that could be outside his field of vision, as illustrated in the diagram below. The system operates in accordance with the ultrasound 'sonar' principle: four ultrasound transducers are located in the rear bumper. They send signals to a control unit, which processes this information and determines the distance of possible obstacles. A loudspeaker controlled by the control unit emits an intermittent tone, proportional to the distance of the obstacle detected. The control unit is activated when reverse gear is engaged: under these conditions it energizes the transducers and sends them a signal request, and receives response signals from them. Via the specific loudspeaker, the control unit emits a signal with an intermittent tone: this sound increases in frequency as the bumper comes closer to an obstacle.If the distance measured from the obstacle increases, or if the driver disengages reverse gear, the sound stops. If the distance measured from the obstacle remains constant, the sound ceases after about 3 seconds. The signal that the reversing light has been switched on is managed by the Body Computer node which forwards this information to the parking sensor control unit via the CAN network.
Functional description The body computer node M001, at pin 1 connector C, receives the signal (positive) that reverse gear is engaged, from the switch I020. From pin 6 connector G, the body computer node informs the parking sensors control unit M084 (pin 13) that reverse gear has been engaged. The control unit M084 supplies the parking sensors unit K097, providing the supply from pin 5 and the earth reference to pin 6. From pins 1, 2, 3, 4, the parking control unit receives the signals provided by the parking sensors unit K097. The parking control unit M084 manages the operation of the loudspeaker P044, used for acoustic signalling of obstacle detection. The system fault is indicated by a warning light located in the instrument panel E050.
