Abstract:
A device for ABS-integrated brake pad wear indication in a motor vehicle, comprising a central ABS or ABS/ASR microcomputer configured to be supplied with wheel speed signals and brake pad wear signals from wheel sensors, means for indicating at least one of fault states and brake pad wear such that, at least wheel by wheel, fixed, single strand lines which transmit wheel speed signals and brake pad wear signals to the microcomputer are selectively plugged in, and are led to a single terminal plug-in connector of a brake control unit containing the microcomputer, and an instrument cluster arranged in a vehicle dashboard and being associated with said means for indicating at least one of fault states and wear, wherein the instrument cluster is connected to the brake control unit via only a single signal path which leads via a single terminal plug-in connector, andstate and/or warning signals are transmittable from the brake control unit by one of pulse width modulation and per protocol to the instrument cluster which comprises at least one dedicated microcomputer which performs one of the pulse width demodulation and protocol demodulation and driving of associated displays.
