Abstract
The invention is based on a method for detecting slip in the driving of generator or starter-generator systems. The alternators of these systems are equipped with electronic control components such as pulse-width-modulated inverters or rectifier bridges. The drive torque of the alternator is transferred to this by means of a belt drive of an internal combustion engine. When slip is detected in a comparison step (3), to which speed-dependent input variables (1, 2) are forwarded, the maximum transferrable drive torque is determined in a torque limiting step (18, 20), and a closed-loop control (23) adjusts the generator output power to said maximum transferrable drive torque.
Claims11
A method for detecting slip (4) in the driving of alternators that are controlled with an electronic machine control such as a pulse-width-modulated inverter or a rectifier, and in the case of which the drive torque is transferred from an internal combustion engine to the alternator via a belt drive,
- wherein, when slip (4) s is detected in a comparison step (3), to which speed-dependent input variables (1, 2) are forwarded, a signal (9) is generated, so that the maximum transferrable drive torque is determined in a torque limiting step (18, 20), and a closed-loop control (23) adjusts the generator output power to said maximum transferrable drive torque.
