Speed signal speed-A
The instrument cluster receives the position signal tw from the antilock brake system (ABS)/automatic stability
control (ASC)/dynamic stability control (DSC) control unit.
The instrument cluster derives the speed signal from the position signal tw and from the position pulse
number (K-number) stored as coding data in the instrument cluster electronics (IKE). The speed signal
(Speed-A) is provided as a signal output for connected control units. The speed information from the speed-A
signal is received by the control units connected by measuring the frequency or period duration.
This speed
information is also made available in the form of a telegram via the instrumentation bus (I-bus) and body bus
(K-bus).
