METHOD FOR EXTENDING THE DIAGNOSTIC CAPABILITY OF CURRENT REGULATORS
摘要
The invention relates to a method and an apparatus for monitoring at least one output stage (18) for an inductive load (26) with a current regulator (12) and an analysis unit (16). Detection of a short circuit to the voltage supply U<SUB>bat</SUB> (24) or to earth (20) is carried out by the comparison of at least one current value in a switching phase of the at least one output stage (18) with at least one current value in a freewheeling phase (30) of the at least one output stage (18).
