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 (050) control unit.


The instrument cluster derives the speed signal ( speed-A ) from the position signal tw and from the position pulse number ( K-number ) stored as coding data in the instrument cluster.


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 made available in the form of a telegram via the body bus ( K-bus).
