  • Patent number: 9494122
    Abstract: The invention relates to a method for meshing a starter pinion (19) of a starting device (16) into a ring gear (13) of an internal combustion engine (10). The internal combustion engine (10) has a driveshaft (22), and the starting device (16) has a starter motor (25), said driveshaft (22) having a variable rotational speed (n). The internal combustion engine (10) is switched off in a method step (S1), and the starter pinion (19), which is not being rotationally driven by the starter motor (25), is then advanced in the direction of the ring gear (13) by a toe-in actuator (28) by means of a toe-in force (FV) in a method step (S2) until the starter pinion contacts the ring gear. A meshing force (FE) is then exerted onto the starter pinion (19) in a controlled manner in an additional method step (S3) in order to mesh the starter pinion (19) into a tooth gap (34) of the ring gear (13).

  • Patent number: 9435312
    Abstract: A diagnostic system and method for a vehicle with a starter-based stop-start system. At least one diagnostic check is performed before stopping the engine as a function of the stop-start system. Both diagnostic checks may be performed. If a diagnostic check indicates a failure of the starter motor or solenoid, operation of the stop-start system is suspended. The system utilizes a sensor to determine if the starter shaft is rotating when the shaft is in a position wherein a gear on the shaft is disengaged. Operability of the starter motor is checked by energizing and then de-energizing the motor without engaging the gear and determining if the shaft rotates. Operability of the solenoid is checked by sensing the rotation of the starter shaft and then energizing the solenoid to move the shaft into a position where the sensor cannot detect rotation of the shaft.

  • Patent number: 8688359
    Abstract: There is provided an idle stop system that can more quickly restart with small noise in conducting idle stop. In preparation for a restart request during an engine inertial rotation, after a motor is rotated in a state where a starter motor is not coupled to the engine, a pinion is engaged with a ring gear during the motor is subjected to inertial rotation like the engine. In this situation, the rotational speed including future pulsation of the engine is estimated with the use of information on the crank angle, and a pinion pushing timing is controlled so that the pinion and the ring gear contact each other with a given rotational speed difference taking a delay time of a pinion pushing unit into consideration.

  • Patent number: 8671786
    Abstract: A starter control apparatus is provided which is used with a starter equipped with a pinion engageable with a ring gear coupled to an output shaft of an engine and a motor operable to rotate the pinion to crank the engine. The starter control apparatus works to determine whether the engine has been placed to continue to run by itself after cranked by the motor or not. When such a condition is encountered, the starter control apparatus releases the engagement of the pinion with the ring gear while keeping the pinion rotated by the motor, thereby decreasing the torque exerted by the ring gear on the pinion to minimize the wear of the pinion.
