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

MODEL 166 up to model year 2016 with CODE 233 (DISTRONIC PLUS) 

MODEL 166 up to model year 2016 with CODE 237 (Active Blind Spot Assist) 

Shows model 166.0 

Location 

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

Task 

The DISTRONIC electric controller unit has the following tasks:

• Actuation, power supply and evaluation of target data from the integral long range radar
• Control of the target evaluation (long range radar)
• Passing on of the object data for vehicle longitudinal regulation to the video and radar sensor system control unit (N62/2) (with code (233) DISTRONIC PLUS))
• Transfer of object data for traffic monitoring to the video and radar sensor system control unit (with code 237 (Active Blind Spot Assist))

The control unit integrated in the DISTRONIC electric 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 electric controller unit via the vehicle dynamics CAN (CAN H) to the video and radar sensor system control unit.

Input and output signals:

The following input signals are received, evaluated and output signals delivered by the DISTRONIC electric controller unit via the vehicle dynamics CAN:

• Input signals 
  • Radar request
  • Diagnosis request
• Output signals 
  • Target data from the radar
  • Diagnostic data

Body 

The DISTRONIC electric controller unit contains a control unit for actuation and evaluation of 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 radar sensor operating on the pulse Doppler principle for independent measurement of distance and speed

The DISTRONIC electric 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 electric 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
