Blind Spot Monitoring Radar Sensor Controller Unit, Basic Function - GF54.71-P-9891A
MODEL all (CAR)
with CODE 22P (Lane tracking package)
with CODE 234 (Blind Spot Monitoring)
Location
The outer rear radar sensors are located on the left and right behind the rear bumper.
Task
The radar sensor transmits bundled electromagnetic waves as so-called primary signals. Objects in the detection range of radar sensor reflect these electromagnetic waves. The radar sensor receives the reflected electromagnetic waves (secondary signals) and evaluates them according to various criteria. In this way, different information can be obtained about the objects.
- Angle or direction to the object
- Distance to the object
- Speed differential
The outer rear radar sensors are connected via the peripherals CAN (CAN PER) to the network architecture of the vehicle.
The outer rear radar sensors operate according to the master/slave principle. The master or slave function can be determined via the connector coding. The master function is defined for the right rear radar sensor. This means that the left rear radar sensor transmits its information via the peripherals CAN to the right rear radar sensor. The right rear radar sensor evaluates the information from both rear radar sensors and transmits corresponding requests and data via the peripherals CAN.
