  • Publication number: 20140162839
    Abstract: In a case of engagement when a clutch K0 disposed between an engine 12 and a motor generator MG is engaged during EV running while a release instruction for the clutch K0 is output, drive of the engine 12 is changed such that a rotation speed NE of the engine 12 approaches a rotation speed NMG of the motor generator MG and, therefore, a drag torque of the engine 12 can be suppressed regardless of an engagement state of the clutch K0, and generation of longitudinal acceleration can be suppressed by reducing a slip time of the clutch K0. Therefore, a control device of a hybrid vehicle 10 can be provided that reduces a driver's uncomfortable feeling in a simplified manner in a case of wrong engagement of the clutch K0.

  • Publication number: 20140124324
    Abstract: A hydraulic control device configured with a source pressure generation section, a hydraulic servo for a clutch provided between an engine and a motor, a control solenoid valve that outputs a regulated source pressure to the hydraulic servo, and a switching section that switches a hydraulic passage, which extends between the source pressure generation section and the hydraulic servo to supply the engagement pressure, between a first and second state in which the hydraulic passage has a high conduit resistance compared to the first state at least until the clutch is engaged. The switching section switches the hydraulic passage into the second state during a failure in which the control solenoid valve is de-energized and the source pressure is directly supplied to the hydraulic servo as the engagement pressure, and switches the hydraulic passage into the first state during normal times when the failure does not occur.

  • Publication number: 20130141571
    Abstract: A soft packaged sealed battery is contained in an airtight container. The airtight container is decompressed and images of the surface shape of the sealed battery in the airtight container before and after decompression are captured by a CCD camera or the like. Whether or not airtightness of the sealed battery is maintained is determined based on a change in the captured images, e.g. a change in the surface shape appearing as luminance differences of pixels. By this determination method, highly accurate airtightness determination is realized by eliminating the influence of invisible fine creases on a sealed battery surface.
