A starter-generator system for motor vehicles permits implementation of various starting methods including direct start and impulse start. The system also facilitates additional operating modes, including generator operation and/or recuperation operation. The starter-generator system electric machine which can be used as the starter and the generator is to be connected by way of a planetary drive with a shaft train situated between an internal-combustion engine and a transmission, the planetary drive being at least partially usable as a centrifugal mass for impulse starting operations.

1. Starter-generator system, which is arranged in use between an internal-combustion engine and a transmission, comprising:a stator fixed to a case and a rotor forming an electric starter-generator machine, and a planetary drive which is in a driving connection with a shaft train which connects an internal-combustion engine and a transmission, said planetary drive including: (i) a ring gear, (ii) a planet carrier with planet gears, (iii) a sun gear non-rotatably connected with the rotor, (iv) a first controllable locking device operable to interlock the ring gear with respect to the case for case interlocking operations during a portion of startup of said engine, and (v) a second controllable locking device operable to interlock the ring gear with gear for planetary drive interlocking operations during another portion of startup of said engine, wherein said starter-generator system is operable in a plurality of operating modes including a centrifugal mass starting operation mode having a first starting phase with said planetary drive out of driving connection with the shaft train and with parts of the planetary drive forming a centrifugal mass accelerated with the rotor and a second starting phase with the accelerated centrifugal mass in driving connection with the shaft train.
