Additional Functions
Signal Conditioning
The following input signals are processed by the function logic section for calculation or as information:
^
Calculation Of Vehicle Speed/Slip
-
Speed sensor signals
^
Calculation Of Lateral Forces
-
Steering angle sensor signal
-
Lateral acceleration sensor signal
-
Yaw rate sensor signal
^
Calculation Of Longitudinal Forces
-
CAN information, engine torque
-
CAN information. current transmission gear
-
Brake pressure sensor signal
^
Information Signals (Operation)
-
Stop lamp switch signal
-
Parking brake switch signal
-
ESP OFF switch signal
-
BAS release switch signal
-
BAS diaphragm travel sensor signal
Function Logic Section
The conditioned input signals are processed in the logic section and converted into output signals.
^
Speed Sensor Signals
The conditioned 4 wheel speed signals are constantly compared with each other and with specified slip thresholds at the front and rear wheels,
depending on vehicle speed.
The following values or control variables are determined by this comparison process.
-
Vehicle Speed
-
Acceleration/Deceleration
-
Brake Slip (ABS)
-
Drive Slip (ASR)
-
Overrun Slip (EBR)
