A starting and generating system for a hybrid vehicle is provided. The system includes a starter-generator which transmits rotational force to the engine to start the engine when the starter-generator is operated as a motor, and is operated as a generator by receiving rotational force of the engine. A motor-generator is operated as a generator by receiving rotational force of the engine and a planetary gear mechanism connects the engine, the starter-generator, and the motor-generator to transmit rotational force between the engine, the starter-generator, and the motor-generator. Additionally, a first brake and a second brake selectively operate rotating elements, which are connected to the starter-generator and the motor-generator among the rotating elements of the planetary gear mechanism, as a fixed element. A controller specifically operates the starter-generator, the motor-generator, the first brake, and the second brake.

Abstract:
A friction starter drive unit comprises a drive pinion for meshing with a starter ring gear. A drive element and a friction clutch are between the drive element and the drive pinion. The friction clutch has a reaction element rotatably fixed to the drive pinion and a pressure element solidly connected to the drive element. The drive element moves relative to the reaction element between uncoupled and coupled positions, and a resilient means biases the reaction element and the drive element toward the uncoupled position. A retaining washer is rotatably fixed to the reaction plate or the drive element. When the retaining washer is rotatably linked to the reaction plate, the resilient means is positioned between the reaction plate and the retaining washer, and, when the retaining washer is rotatably linked to the drive element, the resilient means is positioned between the drive element and the retaining washer.

Abstract:
The invention relates to a method for predetermining a motion state (BZn+1) of a drive shaft (222) of an internal combustion engine (210) on the basis of previous motion states (BZn, BZn−2) of the drive shaft (222), wherein properties (tn−2, ωn−2) allocated to a first previous motion state (BZn−2) and properties (tn, ωn) allocated to a second previous motion state (BZn) are used and the drive shaft (222) assumes periodically recurring angular positions (φn−2, φn, φn+2; φn−1, φn+1). The invention is characterized in that a future motion state (BZn+1) and the properties (tn−1, φn+1) allocated thereto of the drive shaft (222) are determined in an angular position on the basis of the first evaluated previous motion state (BZn−2) and the second evaluated previous motion state (BZn), wherein the angular position (φn+1) of the determined future motion state (BZn+1)of the drive shaft (222) is not equal to an angular position (φn−2, φn) of the first and second previous motion state (BZn, BZn−2).
