Patent ID: 7102246

Claim:
A method for detecting slip ( 4 ) in the driving of rotary current generators that are controlled with an electronic machine control such as a pulse-width-modulated inverter or a rectifier, and with which a drive torque of an internal combustion engine is transferred to the rotary current generator via a belt drive, wherein, in a comparison step ( 3 ), speed-dependent input variables ( 1 , 2 ) are forwarded, wherein, with detection of slip ( 4 ), a signal ( 9 ) is generated, wherein based on the signal, a maximum transferrable drive torque is set in a first torque limiting step ( 18 , 20 ) to reduced torque ( 16 ), and in the event of an acceleration phase of the internal combustion engine, the reduced torque ( 16 ) is reduced additionally in a second torque limiting step, and output variables ( 16 , 22 ) of the torque limiting steps ( 18 , 20 ) are combined at a summing point ( 19 ), and the resulting signal at the summing point ( 19 ) is supplied to a closed-loop control ( 23 ) for limiting the generator output power.
