Long-Range Radar Sensor, Component Description - GF30.30-P-3125RF
Model 205
up to model year 2019
with code 23P (Driving Assistance package)
Model 253
up to model year 2020
with code 23P (Driving Assistance package)
Location
The front long-range radar sensor is located in the center, in front of the radiator.
Tasks
The long-range radar sensor has the following tasks:
- Actuation, power supply and evaluation of target data from the integral long range radar
- Transmission of data for longitudinal directional vehicle control to the radar sensors control unit (N62/1)
- Transmission of data for longitudinal directional vehicle control to the radar sensors control unit
- Transmission of object data to the radar sensors control unit for plausibility checking of the object data from the stereo MFK (A40/13)
- Transmission of object data for collision-avoiding intervention by the brake system to the radar sensors control unit
The control electronics integrated in the long-range radar sensor actuate the long range radar and evaluate the target data. The front long range radar sensor transmits the object data via the suspension FlexRay (Flex E) to the radar sensors control unit.
Input and output signals
The long-range radar sensor transmits and receives the following signals via the chassis FlexRay:
- Input signals
- Output signals
Received signals are evaluated by the integrated control electronics.
Input signals
- Radar request
- Diagnosis request
Received signals are evaluated by the integrated control electronics.
Output signals
- Target data from the radar
- Diagnostic data
Structure
The front long-range radar sensor contains control electronics for actuating and evaluating the long range radar.
Properties of the long range radar:
- Detection range of the long range radar sensor:
- Detection range: s < 30 m for a detection angle of ∠ = 30°
- Detection range: s = 30 to 100 m for a detection angle of ∠ = 20°
- Detection range: s = 100 to 200 m for a detection range of ∠ = 12°
- Carrier frequency: 77 GHz (in accordance with the "Pulse Doppler Principle" for independent measurement of distance and speed)
The front wide range radar sensor must be readjusted using the integrated "Service Adjustment Mode" after replacement (e.g. after an accident repair).
