Abstract: A starter system including a motor, a solenoid assembly having a solenoid switch, a pinion rotated by the motor and moveable into an engaging position in which an engine may be cranked and the solenoid switch is closed to energize the motor from an electric power source, and relay switch regulated by a controller and closed to apply electrical power to the solenoid assembly for actuating the solenoid switch. The controller repeatedly opens and closes relay switch during a starting operation if sensed motor energization voltage monitored by the controller falls below a predetermined threshold level within a predetermined time period after electrical power is applied to the solenoid assembly, whereby electrical power applications to the solenoid assembly are automatically repeated during a starting operation to correct “click-no-crank” events and prevent prolonged power application to the solenoid assembly. A related method is also disclosed.

Abstract: In an engine control device, an automatic engine stop control section automatically stops an engine operating when an automatic engine stop condition is satisfied. An engine start control section supplies electric power to a starter to drive the starter when receiving an initial engine start intention signal transmitted from a push starter and when an automatic engine start condition has been satisfied. An engine start completion detection section detects whether the engine start of the engine has finished. An automatic engine stop permission section permits the automatic engine stop control section to stop the engine operating when the automatic engine stop permission section detects that the engine start has finished at a timing when the engine start control section has started the engine after receiving an initial engine start intention detection signal transmitted from the push starter.

Abstract: A method for guaranteeing starting performance of an engine for maintaining driving performance is provided. The method includes executing a quasi-failure mode in which the engine is changed to a driving state when an engine cranking apparatus state is maintained equal to or less than a threshold for a predetermined period of time. As a result, the engine is driven in the quasi-failure mode while the hybrid vehicle is driven in the EV mode to prevent the vehicle system from being aggravated and fundamentally preventing the degradation in the stability of the vehicle causing driver discomfort.

Abstract: A system and method for starting/stopping an engine in a moving vehicle include stopping the engine, by a controller, in response to a time needed to start the engine from a stopped state and attain an engine speed corresponding to a driveshaft speed when stopping the engine being less than a target time, and starting the engine in response to the time needed reaching the target time. A start/stop vehicle having an engine includes a driveshaft speed sensor and a controller configured to stop the engine while the vehicle is moving with a vehicle speed below a threshold speed in response to a time associated with starting the engine and powering a driveshaft to attain a driveshaft speed measured by the driveshaft speed sensor and stored from a previous engine stopping event being less than a threshold time.

Abstract: The invention relates to an idling stop control device of a vehicle. The control device starts an execution of a decompression control at an engine-speed-decreasing-period timing within an engine-speed-decreasing period when an inclination gradient is a downward slope gradient smaller than a predetermined gradient. The period corresponds to a period between a timing when the engine speed reaches a peak engine speed after the engine speed exceeds a complete explosion engine speed after the execution of the engine restart process is started and a timing when the engine speed decreases to a stable idling engine speed. On the other hand, the control device starts the execution of the decompression control at a complete-explosion-achievement timing when the inclination gradient is a downward slope gradient equal to or larger than the predetermined gradient.
