Shown on removed bumper at the front
Location
The bumper DISTRONIC (DTR) sensors at the front are located on the inside on the left and right on the front bumper.
Shown on removed bumper at the rear
Location
The bumper radar sensors at the rear are located on the inside on the left and right on the rear bumper.
Task
The radar sensors (short range sensor) recognize objects (such as vehicles) in the short range area up to s = 30 m for a maximum detection angle of ∠ = 140°.
Design
The radar sensors are ultra wideband radar sensors with the following properties:
- Radar sensor detection range s = 0.2 to 30 m at a resolution of s = 004 m
- Acquisition angle ∠ = 80° with angle determination and ∠ = 140° only detection (track)
- Radar sensor with f = 24.125 GHz carrier frequency
- Method of operation: short pulse method with f = 5 GHz band width
The high band width of the radar sensors allows a very precise position statement to be made and optimizes separation of objects lying close to each other.
Coding (differentiation) for the individual radar sensors takes place by means of different assignment with ground on pin 5 and 6.
Actuation of the radar sensor and evaluation of data for this takes place by the radar sensors control unit (N62/1) via the sensor-CAN (CAN S).
