  • Publication number: 20170226952
    Abstract: A control apparatus for an internal combustion engine includes circuitry configured to control a fuel injector of the internal combustion engine to stop injecting fuel to reduce torque generated by the internal combustion engine during upshift. The circuitry is to acquire a target injection amount parameter corresponding to a target injection amount of the fuel to be injected by the fuel injector to operate the internal combustion engine based on an operation state parameter corresponding to an operation state of the internal combustion engine. The circuitry is to acquire a minimum injectable amount parameter corresponding to a minimum injectable amount of the fuel injectable from the fuel injector. The circuitry is to control the fuel injector to start injecting the fuel when the minimum injectable amount parameter exceeds the target injection amount parameter while the fuel injector is controlled to stop injecting the fuel during the upshift.

  • Publication number: 20170218835
    Abstract: A control device for a vehicle includes an opening degree sensor to detect an opening degree of a wastegate valve disposed in a bypass passage bypassing a turbine. Circuitry is configured to stop an internal combustion engine while the vehicle is driven by a motor in a motor drive mode. The circuitry is configured to calculate a target opening degree of the wastegate valve to be larger than a maximum error between the opening degree detected by the opening degree sensor and an actual opening degree of the wastegate valve. The circuitry is configured to control the wastegate valve such that the opening degree detected by the opening degree sensor is equal to the target opening degree while the vehicle is driven in the motor drive mode.

    Abstract: Disclosed herein is a semiconductor integrated circuit which controls the quality of an image and includes a viewer detector, a region specifier, and a controller. The viewer detector detects the number of viewer(s) watching the image and a gaze region being watched by the viewer within the image. If the number of viewers is plural, the region specifier specifies a local region of the image as a target region based on a plurality of gaze regions being watched by the viewers. The controller performs image quality control on the target region.

  • Publication number: 20170114736
    Abstract: A control device for an internal combustion engine includes a throttle valve opening degree detector, an air bypass valve controller, and a torque reduction controller. The throttle valve opening degree detector detects an opening degree of a throttle valve which is provided downstream with respect to a compressor of a supercharger. The air bypass valve controller opens an air bypass valve based on a reduction change in the opening degree of the detected throttle valve. The air bypass valve is configured to open and close a bypass path. The torque reduction controller controls the throttle valve to reduce the opening degree of the throttle valve while an automatic transmission connected to the internal combustion engine is in an acceleration shifting in order to execute a torque reduction control. The air bypass valve controller maintains the air bypass valve in a close state during the torque reduction control.

  • Patent number: 9413525
    Abstract: A frequency tracking loop receives a result from a phase detector that detects an advance and a retard of a phase between input data and an extracted clock signal, and conducts a control to reduce a frequency deviation between the input data and the extracted clock signal. A phase interpolator adjusts a phase of the clock signal subjected to spread-spectrum frequency modulation on the basis result of the frequency deviation in the frequency tracking loop, and outputs the extracted clock signal. In the frequency tracking loop, the frequency deviation between the data signal and the clock signal is corrected to offset a variation of the frequency of the clock signal, on the basis of the frequency modulation information related to the clock signal subjected to the spread-spectrum frequency modulation which is input to the phase interpolator. The frequency of the clock signal seemingly follows the frequency of the data signal.

  • Publication number: 20160052511
    Abstract: A control device for a hybrid vehicle includes a push-start mode and a motor start mode. The push-start mode transmits a driving force from driving wheels to the engine via a first transmission route at a speed detected by a speed detection means equal to or more than a predetermined speed to start the engine. The motor start mode starts the engine using a driving force of the motor at a speed equal to or less than the predetermined speed as well as in a stopped state. At a speed outside a speed range that either mode is executable when a start command of the engine occurs in driving only using the electric motor as the driving source, a control means performs the driving force reduction control for reducing a driving force transmitted from the electric motor to the driving wheels of the vehicle.
