The ETS control module is divided up functionally as follows:
-
Signal conditioning
-
Logic section
-
Safety circuit
-
Additional functions
-
Signal conditioning
The following signals are conditioned for the logic section:
-
4 speed sensors
-
Stop lamp switch
-
CAN data
-
Logic section
The conditioned input signals are processed in the logic section and converted into output signals.
The logic section is divided up functionally as follows:
-
ETS control mode
-
Temperature monitoring
ETS control mode
The control mode for brake intervention at the rear axle is recognized for the left and right rear wheel from the vehicle speed and ETS slip recognition.
Switching on condition: Wheel speed > 3 km/h above vehicle speed
Switching off condition when one wheel controlled: Wheel speed < 2 km/h above vehicle speed
Switching off condition when 2 wheels controlled: Wheel speed < 1 km/h above vehicle speed
Speed range: 0-80 km/h
If the switching on condition is maintained during acceleration above 80 km/h, the control mode is continued up to max. 130 km/h.
The control mode for brake intervention at the front axle is recognized for the left and right front wheel from the vehicle speed and ETS slip recognition.
Switching on condition for one front wheel: Wheel speed > 5 km/h above vehicle speed
Switching on condition for second front wheel: Wheel speed > 3 km/h above vehicle speed
Switching off condition for one front wheel controlled: Wheel speed < 3 km/h above vehicle speed
Switching off condition for two front wheels controlled: Wheel speed < 3 km/h above vehicle speed or both rear wheels controlled
The ETS control mode at the front axle is permitted when the switching on conditions are met in the speed range of 0-40 km/h.
If the switching on condition is maintained during an acceleration above 40 km/h, the control mode is continued up to max. 80 km/h.
