  • Integrated control method and integrated controller of powertrain
    Patent number: 10814877
    Abstract: An integrated controller of a powertrain of a vehicle and a control method thereof, to determine an optimum shifting stage of the vehicle, may include a cost function having a driving distance per fuel consumption amount obtained through the simulation of a vehicle model by use of the demand power of the engine as an input value, wherein an optimum shifting stage is determined using the cost function to control an engine throttle in addition to controlling a transmission based on the optimum shifting stage.
    Type: Grant

  • Needle lift estimation system of common-rail injector
    Patent number: 6513502
    Abstract: The present invention provides a needle lift estimation system of a common-rail injector on the basis of solenoid voltage and measured current. In addition, the present invention provides a method for estimating a needle lift that comprises: measuring a current that is supplied to a solenoid; estimating an armature lift and an armature speed on the basis of the current of the solenoid; and estimating a needle lift from a state equation having the measured solenoid current, the estimated armature lift, and the estimated armature as state variables.
