    摘要: The invention relates to a pulse starting method for an internal combustion engine in which, during a wind-up phase, a flywheel mass is accelerated in a rotary driven fashion and then during a coupling phase, the rotating flywheel mass is coupled to a rotatably supported shaft of the engine, preferably the crankshaft, in order transmit torque, which is distinguished by the fact that during the wind-up phase (15) and/or the coupling phase (21, 22), the rotational speed progression of the flywheel mass (3) is evaluated, that based on this evaluation, a deduction is made as to whether a successful start of the engine (1) is possible, and that if a successful start is not expected, the shaft (2) is used to bring the engine (1) into an operating position that is favorable for a subsequent second starting attempt.

    摘要: The invention relates to a starting/driving unit for an internal combustion engine (VM) of a motor vehicle with at least two starting methods, which has a clutch (K) between the crankshaft (KW), the engine (VM), and the vehicle transmission (FG) as well as an electric machine which is connected to the engine (VM) by way of the clutch (K). With the electric machine, the two starting methods can be executed in an optimal fashion solely by virtue of the fact that through rotation of the crankshaft by means of the electric machine, each starting method is preceded by a start clearing phase in which the starting conditions are detected when the clutch is engaged, a decision is made as to the subsequent operating phases (direct start phase, positioning phase, preinjection phase, impulse start phase) and their starting parameters are determined.
