Traction Control Module: Description and Operation
GF42.45-P-4500-01E Function of ESP control module
The ESP and BAS control unit (N47-5) (models 203, 209), ESP control unit (N47-5) (model 163) is divided up functionally as follows:
^
Signal conditioning
^
Function logic component
^
Safety circuit
^
Additional functions
Signal conditioning
The following input signals are processed by the function logic component for calculations or as information:
^
Calculation of vehicle speed/slip signals of the 4 rpm sensors
^
Calculation of lateral forces
Steering angle sensor signal (N49) via. engine compartment (CAN-C)
ESP lateral acceleration sensor signal (B24/2) (models 203, 209), lateral acceleration sensor (B43) (model 163)
ESP yaw rate sensor signal (N64) (models 203, 209), (B45) on (model 163) BAS diaphragm travel sensor signal (A7/7b1)
