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)
Shows MODEL 218.3
Location
The DISTRONIC electric controller unit is located in the middle behind the front brand emblem in the radiator trim. The brand emblem shields the DISTRONIC controller unit against external effects (for example dirt, ice or insects).
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)
The control electronics integrated in the DISTRONIC controller unit actuates the long range radar and evaluates its target data. The target data of the long range radar transmits the DISTRONIC controller unit via the dynamics CAN (CAN H) to the video and radar sensor system control unit (N62/2). The listed tasks are realized through:
- Receiving signals
- Sending signals
Receiving signals
The DISTRONIC controller unit receives the following signals via the vehicle dynamics CAN:
- Radar requirements of the long range radar (vehicle/operation-specific data
- Diagnosis requests
Sending signals
The DISTRONIC controller unit transmits the following signals via the vehicle dynamics CAN:
- Target data of the long range radar
- Diagnostic data
Structure
The long range radar and control electronics are integrated in the DISTRONIC controller unit.
Properties of the long range radar:
- Detection range: s = 0 to 200 m for a detection angle of ∠ = 18°
- Detection range: s = 0 to 60 m for a detection angle of ∠ = 60°
- Carrier frequency: f = 77 GHz long range radar (Pulse duplicator concept 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".
