Long-range radar sensor, component description - GF30.30-P-3125CAM
MODEL 207.3/4 as of model year 2014 with CODE 23P (Driving Assistance package Plus)
Location
The front long-range radar sensor is located in the center, in front of the radiator.
Task
The long-range radar sensor has the following tasks:
- Actuation, power supply and evaluation of target data from the integral long range radar
- Transfer of object data for longitudinal vehicle control to the radar sensors control unit (N62/1) (for code (233) DISTRONIC PLUS)
- Transfer of object data for traffic monitoring to the radar sensors control unit (with code (237) ACTIVE BLIND SPOT ASSIST)
The control electronics integrated in the long-range radar sensor actuate the long range radar and evaluate the target data.
The target data of the long-range radar is transferred to the radar sensors control unit by the long-range radar sensor via the suspension FlexRay (Flex E).
Input and output signals
The following input signal are received by the long-range radar sensors and evaluated and the output signals sent via the suspension FlexRay:
- Input signals
- Output signals
Input signals
- Radar request
- Diagnosis request
Output signals
- Target data from the radar
- Diagnostic data
Body
The front long-range radar sensor contains control electronics for actuating and evaluating the long-range radar.
Properties of long range radar:
- Detection range of the radar sensor s = 0 to 200 m for a detection angle of ∠ = 18°
- Detection range of the radar sensor s = 0 to 60 m for a detection angle of ∠ = 60°
- 77 GHz radar sensor operating on the pulse Doppler principle for independent measurement of distance and speed
The long-range radar sensor must be readjusted using the integrated "Service Adjustment Mode" after replacement (e.g. after an accident repair).
View of radiator grille
The radar plate is a radar-permeable cover in the radiator grille, which is required for the Distronic PLUS to function correctly.
Its tasks are as follows:
- Shielding against external effects (such as dirt, ice or insects)
- Ensuring optimal transmission and reception properties of the radar sensor
