  • Patent number: 10480438
    Abstract: Disclosed herein is a fuel injection control device for a direct injection engine including an engine body (engine 1) and a fuel injection control unit (engine controller 100). The fuel injection control unit injects a fuel in a predetermined injection mode into a combustion chamber (17) such that while the engine body is warm, an air-fuel mixture layer and a heat-insulating gas layer, surrounding the air-fuel mixture layer, are formed in the combustion chamber at a point in time when an air-fuel mixture ignites, and changes the injection mode of the fuel into the combustion chamber such that while the engine body is cold, the lower the temperature of the engine body is, the thinner the heat-insulating gas layer becomes.

  • Patent number: 10340834
    Abstract: A drive system shifts an inverter from a gate blocking state to a three phase-on state. When it is determined that electric current flows in a diode of an upper arm of the inverter by referring to a phase current of each phase of a motor, the drive system turns on a switching element of the upper arm and thereby shifts the inverter to an upper arm three phase-on state. When it is determined that electric current flows in a diode of a lower arm of the inverter by referring to the phase current of each phase, the drive system turns on a switching element of the lower arm and thereby shifts the inverter to a lower arm three phase-on state.

  • Patent number: 10309338
    Abstract: A fuel injection valve (6) is configured such that the effective opening area of an injection port (61) increases as its lift amount increases. A fuel injection control unit (an engine control unit 100) injects fuel in a lift amount changing mode wherein, when fuel is injected into a combustion chamber (17) in the terminal period of the compression stroke, the lift amount of the fuel injection valve is set to a predetermined large lift amount in the earlier period of the injection period, and in the later period of the injection period following the earlier period of the injection period, the lift amount is set to a small lift amount smaller than the large lift amount and is in a range where the fuel injection speed increases.

  • Publication number: 20190100214
    Abstract: A power control ECU controls electric power and engine power of a hybrid vehicle. The power control ECU includes a request driving force calculating portion that calculates a request driving force calculated in accordance with an accelerator operation amount, a travel driving force calculating portion that calculates a travel driving force as a value that belatedly follows the request driving force, and a dashpot control processing portion. The dashpot control processing portion sets a value of the request driving force as a value of a final request driving force used to calculate request engine power when a difference of the request driving force with respect to the travel driving force is less than a predetermined positive value, and sets a value that belatedly follows the request driving force when the difference is greater than or equal to the predetermined positive value.

  • Publication number: 20180298841
    Abstract: A vehicle includes two accelerator position sensors and an electronic control unit. The two accelerator position sensors are configured to detect accelerator operation amounts. The electronic control unit is configured to perform drive control based on the accelerator operation amounts from the two accelerator position sensors. The electronic control unit is configured to, when failure occurs in one accelerator position sensor out of the two accelerator position sensors, perform the drive control based on the accelerator operation amount from the other accelerator position sensor out of the two accelerator position sensors, the accelerator operation amount being restricted by an accelerator operation amount upper limit that has a tendency of becoming larger as the vehicle speed is larger.

  • Patent number: 10008969
    Abstract: When a voltage (auxiliary power supply voltage) on an auxiliary power supply line is instantaneously decreased to be smaller than a resetting voltage, a resetting operation is automatically started in each of the MG-ECU and the HV-ECU to perform an initialization process. After the resetting operation of the MG-ECU and/or the HV-ECU, the MG-ECU causes a converter to start a forced discharging operation when a DC voltage of a first smoothing capacitor is higher than a first reference voltage, and/or when a DC voltage of a second smoothing capacitor is higher than a second reference voltage.
