A starting system for an internal combustion engine.

摘要

The system includes a direct-current voltage supply (30), an electric starter motor (2) for rotating a movable pinion (6), and an electromagnetic operating device (3) which, when it receives an excitation current, moves the pinion (6) to couple it for rotation with a rotary member (7) of the internal combustion engine. In operation, an electronic control unit (35, 37-40) cuts off the current supply to the electromagnetic operating device (3) as soon as the speed of rotation of the engine shaft exceeds a predetermined threshold and the acceleration of the shaft is less than or equal to zero. <IMAGE>
