摘要： An engine start system which may be employed in automotive idle stop systems. To start an engine, the system brings a pinion gear into engagement with a ring gear coupled to the engine and turns on an electric motor to rotate the ring gear through the pinion gear to crank the engine. When it is requested to start the engine during deceleration of the engine before stop thereof, the system thrusts the pinion into engagement with the ring gear and then turns on the motor to rotate the pinion gear, in other words, delays the activation of the motor until after the pinion gear has engaged the ring gear. This minimizes mechanical impact or noise arising from the engagement of the pinion gear with the ring gear and improves the reliability in engagement with the ring gear during the deceleration of the engine and durability of the system.

摘要： A control apparatus for controlling a starter used to start an engine mounted on a vehicle, the starter generating a torque and having a first gear mechanically engaged with a second gear of the engine to start the engine. The control apparatus includes a trigger circuit adapted to output a trigger signal in response to a start request; a detection circuit adapted to detect an electrical state and a mechanical state of the starter while the starter is powered on; and a controller adapted to control power on and off of the starter. The controller powers on the starter in response to the trigger signal outputted by the trigger circuit, and powers off the starter when the controller detects that a predetermined condition is satisfied based on the state of the starter.

摘要： In a system, a pinion shift unit starts shift of a pinion to a ring gear for engagement therebetween during an internal combustion engine coasting in a forward direction after an automatic stop of the internal combustion engine. An engagement determining unit determines whether the pinion and the ring gear have any one of first and second positional relationships therebetween. The first positional relationship represents that the pinion is at least partly engaged with the ring gear. The second positional relationship represents that the pinion is in abutment with the ring gear. When an engine restart condition is met before it is determined that the pinion and the ring gear have any one of first and second positional relationships therebetween after the start of the shift of the pinion to the ring gear, a rotation adjusting unit adjusts a start timing of rotation of the pinion.

摘要： 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.

摘要： A ring gear is connected to a crank shaft of an engine. A pinion is placed to face to the ring gear. When the engine is started, an ECU performs cranking of the engine under a state where the ring gear and the pinion are in mesh. The ECU releases the mesh state of the ring gear and the pinion after completion of the cranking of the engine. In particular, the ECU performs dispersion control to increase a degree of dispersion of a mesh portion of the ring gear which is meshed with the pinion when the rotation of the ring gear is stopped according to the engine stop. The dispersion control prevents the mesh portion of the ring gear and the mesh portion of the pinion from progressing abrasion and avoiding defect.
