Elektronisches Steuergerät für Kraftfahrzeuge, insbesondere elektronisches Bremssteuergerät

摘要

The braking control has a circuit (9,..17) for providing a test current fed through the controlled load (5), with evaluation of the test current amplitude, for detecting a potential difference between the earth potentials (M1, M2) of the control device (1) and the controlled load. The a potential difference between the 2 earth potentials is indicated counter-measures are initiated for protecting the components of the control device from damage, e.g. the power switches (8) used to supply the electrical energy for the load are disconnected.
