  • Patent number: 9944278
    Abstract: A vehicle includes an engine, a first motor generator, a second motor generator, a transmission, a differential device, and an electronic control unit. The transmission includes an input shaft, an output shaft, and a clutch. The electronic control unit is configured to detect a rotation speed difference between the input shaft and the output shaft when the clutch is controlled so as to be brought into a power transmission shut-off state. The electronic control unit is configured to, when the rotation speed difference detected by the electronic control unit is smaller than a target rotation speed difference between the input shaft and the output shaft that occurs in a case where the power transmission shut-off state of the clutch is established, suppress cranking of the engine by the first motor generator.

  • Publication number: 20180080401
    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.

  • Publication number: 20180058366
    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.

  • Patent number: 9611795
    Abstract: A PM-ECU configured to control a drive torque of a vehicle is configured to be stopped in response to a driver's operation of a start switch and then activated in response to a driver's re-operation of the start switch. The PM-ECU is configured to be activated and place a restriction on the drive torque of the vehicle, in response to a re-operation of the start switch after the PM-ECU is stopped in response to an operation of the start switch. The PM-ECU is configured to remove the restriction on the drive torque in response to a reduction of an operation amount by which an accelerator pedal is operated.

  • Publication number: 20170093319
    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.

  • Patent number: 9464712
    Abstract: A vehicle includes a motor, a resolver which detects a rotation angle of the motor, an automatic transmission which shifts rotation of the motor and transmits the shifted rotation to a drive shaft, and an ECU which performs learning control for correcting an error of the resolver and shift control of the automatic transmission. The ECU controls the automatic transmission such that, when the learning control is performed, a gear ratio becomes higher at a prescribed vehicle speed, than that when the learning control is not performed. By controlling the automatic transmission as described above, even when the vehicle is traveling at a low speed, a rotation speed of the motor easily reaches a rotation speed at and above which the learning control of the resolver can be performed. Accordingly, an opportunity to perform the learning control of the resolver can be obtained early.

    Abstract: A combustion chamber structure for an engine is provided. The structure includes a piston formed with a downward dented cavity in a central part of an upper surface thereof, and a cylinder head forming a combustion chamber having a pent-roof shape. The upper surface of the piston has an annular part extending from an outer edge of the cavity to an outer edge of the upper surface, and surrounding the outer edge of the cavity. The annular part is formed with first and second piston upper surface portions. When the piston is at a top dead center, a ratio of a volume of a space formed between the first piston upper surface portion and a bottom surface of the cylinder head with respect to a volume of a space formed between the second piston upper surface portion and the bottom surface becomes below a predetermined value.

  • Patent number: 9300233
    Abstract: A vehicle including an AC rotating electric machine, an inverter, and an electronic control unit is provided. When an overcurrent abnormality occurs, i.e., phase current of a motor-generator exceeds a permissible value, in a high rotational speed region, the electronic control unit performs control (upshift control) for shifting up an automatic transmission provided between the motor-generator and driving wheels, or control (neutral control) for bringing the transmission into a released state, so as to reduce the rotational speed of the motor-generator. If phase current is detected even when an all-gate turn-off command is generated to the inverter while the rotational speed of the motor-generator is reduced to be within a low rotational speed region under the upshift control or neutral control, the electronic control unit determines that a short-circuit fault occurs in the inverter.
