  • Patent number: 10208694
    Abstract: A method for controlling a plurality of injectors installed in the same cylinder of an engine may include determining whether an electrical failure occurred in any of the injectors, and entering a fail-safe mode when an electrical failure has occurred only in one of the plurality of injectors in the same cylinder.

  • Patent number: 10202922
    Abstract: A startup control device controls a starter motor. The startup control device includes lock determination circuitry and motor control circuitry. The lock determination circuitry estimates a current value supplied to the starter motor based on a temperature of a battery, a remaining electricity amount in the battery, and an output voltage of the battery when the battery supplies electricity to the starter motor, determines a threshold period of time according to the current value estimated, and determines that an internal combustion engine does not start if a rotational speed of the internal combustion engine does not exceed a referenced speed within the threshold period of time after starting supplying electricity to the starter motor. The motor control circuitry stops supplying electricity to the starter motor when the lock determination circuitry determines that the internal combustion engine does not start after starting supplying electricity to the starter motor.

  • Patent number: 10196995
    Abstract: Methods, devices, estimators, controllers and algorithms are described for estimating the torque profile of an engine and/or for controlling torque applied to a powertrain by one or more devices other than the engine itself to manage the net torque applied by the engine and other device(s) in manners that reduce undesirable NVH. The described approaches are particularly well suitable for use in hybrid vehicles in which the engine is operated in a skip fire or other dynamic firing level modulation manner—however they may be used in a variety of other circumstances as well. In some embodiments, the hybrid vehicle includes a motor/generator that applies the smoothing torque.

  • Patent number: 10190561
    Abstract: A method of rapid starting an internal combustion engine includes determining that the engine is stopped and detecting an engine start request. The method also includes enabling a starter assembly having a brushless electric motor including a stator and a rotor and configured to drive a pinion gear, and engaging the pinion gear with the engine flywheel. The method also includes determining a present angular position of the rotor relative to the stator configured to generate a first rotor torque. The method additionally includes applying an electrical current to the motor, in response to the determined angular position of the rotor, to turn the rotor to a predetermined starting angular position configured to provide a second torque that is greater than the first torque. Furthermore, the method includes commanding the motor to spin the rotor and thereby apply the second torque via the pinion gear to start the engine.
