Component description for DISTRONIC electric controller unit - GF30.30-P-3213FQ

MODEL 218 with CODE (233) Distronic Plus with CODE (237) Active Blind Spot Assist 

Location 

The DISTRONIC electric controller unit is located in the middle behind the front brand emblem.

Task 

The DISTRONIC controller unit fulfills the following tasks:

• Actuation, power supply and evaluation of the target data from the integral long range radar
• Control of the target evaluation (long range radar)
• Transmission of the object data for automatic distance regulation to video and radar sensor system control unit (N62/2)

The control unit integrated in the DISTRONIC controller unit actuates the long range radar and evaluates the target data.

The target data from the long range radar is transferred by the DISTRONIC control unit via the vehicle dynamics CAN (CAN H) to the video and radar sensor system control unit.

The executed tasks are realized through reception, evaluation and transmission of the following signals:

• Receive signals 
• Transmit signals 

Receive signals 

The DISTRONIC controller unit receives the following signals via the vehicle dynamics CAN:

• Radar request
• Diagnosis request

Transmit signals 

The DISTRONIC controller unit transmits the following signals via the vehicle dynamics CAN:

• Target data from the radar
• Diagnostic data

Design 

The DISTRONIC controller unit consists of a control unit and the long range radar.

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 long range 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 grille with integral 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
