  • Patent number: 9803607
    Abstract: An electromagnetic switch device for a starter includes a pinion-pushing solenoid for pushing out a pinion toward a ring gear of an engine by a plunger thereof, and a motor-energizing solenoid for energizing the motor. The electromagnetic switch device is configured to detect a magnetic flux change in a magnetic circuit of the motor-energizing solenoid due to displacement or deformation of a core of the motor-energizing solenoid caused when the plunger of the pinion-pushing solenoid abuts against a stopper, to determine a timing to start current supply to the motor-energizing solenoid.

  • Patent number: 9341124
    Abstract: An engine speed predicting system for a vehicle includes a first calculator, a second calculator, and a switch which may be realized by software. The first calculator calculates a predicted speed of an engine of the vehicle during forward rotation of the engine when speed of the engine is decreasing after fuel stops being burned in the engine. The second calculator calculates a predicted speed of the engine during reverse rotation of the output shaft of the engine. The switch serves to select one of the first calculator and the second calculator which is to be used in calculating the predicted speed of the engine depending upon whether the predicted speed lies during the forward rotation or during the reverse rotation of the output shaft of the engine. This ensures the accuracy in predicting the speed of the engine regardless of the direction of rotation of the engine.

  • Patent number: 8793061
    Abstract: A control device performs fuel injection without cranking when engine-speed Ne is within a first-range (Ne>N1) and an engine-restart request occurs. The device performs the cranking after the synchronization in rotation-speed between pinion and ring gears, and the gear meshing operation between them when the engine-speed Ne is within a second range (N1?Ne>N2) and the engine-restart request occurs. The device performs the cranking after the gear meshing operation and drives a starter to rotate the pinion gear when the engine-speed Ne is within a third-range (N3?Ne) and the above request occurs. When the above request occurs in an engine restart ready-range (N2?Ne>N3), the control device performs the cranking after the engine-speed Ne is decreased to a value within the third-range (N3?Ne) and after the completion of the gear meshing operation.
