Abstract
A method for optimizing the starting torque and for reducing the electrical power usage of a starter-generator of an internal combustion engine. The starter-generator is configured as an electrical machine, which is operated using an inverter or an indirect a.c. converter the electrical power P being made available by a vehicle battery. Before the imaginary turning point ( ) on the torque curve ( ) of the starter-generator is reached, the phase current of the electrical machine is limited. The electrical machine is controlled from the point at which a limiting point ( ) is reached along the electrical limiting power curve ( ) (P=const), such that the electrical power P corresponds to that at the stationary operating point ( ) of the electrical machine.
