(Component Description For DISTRONIC Electric Controller Unit - GF30.30-P-3213RD)
Model 172.4
up to model year 2016
with code 233 (DISTRONIC PLUS)
Show on model 172.4
Location
The DISTRONIC electric controller unit is located in the middle in radiator trim behind the front brand emblem.
Tasks
The DISTRONIC controller unit fulfills the following tasks:
- Power supply and actuation of the integral long range radar
- Evaluation of target data for the integral long range radar
- Control of the target evaluation (long range radar)
- Transmission of data for longitudinal directional vehicle control to the radar sensors control unit (N62/1)
The control electronics integrated in the DISTRONIC controller unit actuate the long range radar and evaluate its target data.
The target data from the long range radar is transferred by the DISTRONIC controller unit via the vehicle dynamics CAN (CAN H) to the radar sensors control unit.
The tasks listed are realized through reception, evaluation and transmission of signals:
- Receiving signals
- Sending signals
Receiving signals
The DISTRONIC controller unit receives the following signals via the vehicle dynamics CAN:
- Radar request
- Diagnosis request
Sending signals
The DISTRONIC controller unit transmits the following signals via the vehicle dynamics CAN:
- Target data from the radar
- Diagnostic data
Body
There are control electronics integrated in the DISTRONIC controller unit which actuate the long range radar and evaluate its data. Properties of the 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 DISTRONIC controller unit must be newly adjusted after exchange (e.g. after an accident repair) using the integrated "service adjustment mode".
View of radiator trim with integrated brand emblem
The cover for the DISTRONIC controller unit is designed as a radar transparent brand emblem and has the following tasks:
- Shielding against external effects (such as dirt, ice or insects)
- Ensuring optimal transmission and reception properties of the radar sensor
