Location
The DISTRONIC electric controller unit is located in the middle in front of the radiator.

Task
The DISTRONIC electric controller unit has 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)
- Transfer of object data for the longitudinal vehicle regulation to the radar sensors control unit (N62/1) (to 31.5.11) or to the video and radar sensor system control unit (N62/2) (as of 1.6.11) (for 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 electronic control circuitry integrated into the DISTRONIC control unit actuates the long range radar and evaluates the target data.
The DISTRONIC controller unit the target data from the long range sensor from the DISTRONIC controller unit via the dynamics CAN (CAN H) to the radar sensors control unit or 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 via the vehicle dynamics CAN:
- Input signals
- Output signals

Input signals
- Radar request
- Diagnosis request

Output signals
- Target data from the radar
- Diagnostic data

Design
The DISTRONIC control unit contains electronic control circuitry for actuation and evaluation of 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 Angular = 18°
- Detection range of the radar sensor s = 0 to 60 m for a detection angle of Angular = 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".

A Radar plate

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
