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 made available as a signal output for connected control units. The speed information from the speed-A signal is received by the connected control units by measuring the frequency or period duration. This speed information is also made available in the form of a diagram via the instrument bus (I-bus ) and body bus (K-bus ).
