  • Publication number: 20190088959
    Abstract: The manufacturing method of the present invention is to manufacture a fuel cell stack by heating a stack of fuel cell single cells each of which includes organic substance-containing inorganic sealing members, a separator, an anode electrode, an electrolyte and a cathode electrode. The organic substance in the organic substance-containing inorganic sealing members is removed by heating the stack while supplying an oxygen-containing gas to fuel channels on the anode electrode side and externally applying an electric current so as to migrate charges from the anode electrode to the cathode electrode.

  • Patent number: 10232698
    Abstract: A mode transition control device a hybrid vehicle has a transmission control unit that prevents a second power generation system from overheating while traveling in a series HEV mode. When a battery is at a power generation request threshold value or lower, the vehicle travels in a “series HEV mode,” in which the first electric motor is utilized as a drive source and receives electrical power from the second motor/generator and the battery. The transmission control unit controls the traveling mode to transition from the “series HEV mode” to a “parallel HEV mode” when the vehicle speed has reached a switchover vehicle speed. When a temperature rise of the second power generation system is predicted while traveling in the “series HEV mode,” the transmission control unit changes the switchover vehicle speed to a slower switchover vehicle speed that was used prior to a determination of the temperature rise.

  • Patent number: 10233859
    Abstract: An internal combustion engine includes a port injector that injects fuel into an intake port and a direct injection injector that injects fuel directly into a combustion chamber. When the internal combustion engine is in a low load condition while requiring fuel injection, a controller stops fuel injection through the port injector so that an entire required fuel injection amount is injected through the direct injection injector. As a result of this processing, the fuel pressure of the direct injection injector is reduced quickly in the low load condition.

  • Patent number: 10221947
    Abstract: A method controls synchronization of a pinion rotating on a primary shaft driven by a traction machine of a vehicle and rotatably connected to a secondary shaft of a parallel shaft gearbox without synchronization mechanisms. The method includes sending to the traction machine, before coupling of the pinion on the primary shaft, a torque command which depends on a torque signal calculated to minimize a difference between a primary speed and a secondary speed multiplied by a reduction ratio between the primary shaft and the secondary shaft. The calculated torque signal is limited in amplitude when the speed difference is greater in absolute value than a desired accuracy on the targeted primary speed upon completion of the synchronization. The calculated torque signal is saturated on a maximum or minimum torque of the traction machine if the calculated torque signal is not between the maximum or minimum torque.

    Abstract: A display apparatus includes: a variable compression ratio mechanism which is capable of modifying an engine compression ratio of an internal combustion engine and a display displaying a state of a present engine compression ratio. For example, when a driving at an engine compression ratio with a good fuel economy is carried out, a display switching is not unnecessarily carried out even under a vehicular acceleration and the display can cause a driver to be recognized that the driving is carried out in a good fuel economy state. On the other hand, when the driving state is switched from the driving state of good fuel economy to that of a bad fuel economy due to an abrupt depression of an accelerator pedal, the display of the engine compression ratio is accordingly varied.

The first target secondary pulley pressure Psteng is outputted as a target secondary pulley pressure Ps(n) when a target secondary pulley pressure Ps(n?1) in a previous control cycle is less than or equal to the first target secondary pulley pressure Psteng; the offset value Psteng+PO is outputted as the target secondary pulley pressure Ps(n) when the target secondary pulley pressure Ps(n?1) in the previous control cycle is greater than or equal to the offset value Psteng+PO; and otherwise, the target secondary pulley pressure Ps(n?1) in the previous control cycle is outputted as the target secondary pulley pressure Ps(n), thereby suppressing an oscillation in the target secondary pulley pressure Ps(n).

  • Patent number: 10218016
    Abstract: A fuel cell system has an oxidant supplying device configured to supply oxidant gas to a fuel cell, a fuel supplying device configured to supply fuel gas to the fuel cell and a combustor configured to burn fuel off-gas and oxidant off-gas discharged from the fuel cell and discharge thereof. The a control method for the fuel cell system includes a power generation control step of supplying the fuel gas and the oxidant gas to the fuel cell and causing the fuel cell to generate power. The a control method further includes a stop control step of stopping the supply of the fuel gas to the fuel cell and supplying the oxidant gas to the combustor on the basis of an amount of unburned fuel gas of the fuel cell system in the case of stopping the fuel cell system.

  • Patent number: 10207715
    Abstract: An automatic transmission control device implements a downshift by disengagement of a clutch that is engaged in a gear position before the downshift. It is determined whether an engine state is in a predetermined region in which a change of an engine torque per a change of an accelerator pedal opening is smaller than that in another region, and the engine torque is within a predetermined range, and an engine rotational speed is within a predetermined range. It is determined whether an operating state is in a predetermined state of accelerator operation in which the accelerator pedal opening is larger than a predetermined value, and an accelerator pedal opening change rate has an absolute value smaller than a predetermined value. The downshift is inhibited in response to determination that the engine state is in the predetermined region and the operating state is in the predetermined state of accelerator operation.

  • Patent number: 10210407
    Abstract: A traffic signal detection device includes a narrow-angle camera, a wide-angle camera having an angle of view wider than the narrow-angle camera, and a traffic signal detector configured to detect a traffic signal from at least any of a narrow-angle image captured by the narrow-angle camera and a wide-angle image captured by the wide-angle camera. The traffic signal detector selects, as a detection result, any of a traffic signal detected from the narrow-angle image and a traffic signal detected from the wide-angle image, on the basis of a deceleration start region in which a vehicle should start deceleration, the deceleration start region calculated from a position of a traffic signal with respect to the vehicle and a speed of the vehicle in order to stop the vehicle at a stop position with respect to the traffic signal.

  • Publication number: 20190051882
    Abstract: A busbar module includes a busbar holding plate and a busbar cover attached to the busbar holding plate. The busbar holding plate includes a busbar holding face and a bearing including a hole and a wall to define the hole. The busbar cover includes protrusions protruding toward each other in the axial direction at positions corresponding to the hole. The protrusions are opposed to each other with a gap less than a dimension of the hole in the axial direction. The protrusions are disposed in the hole to rotate the busbar cover about the protrusions between a covering position and an uncovering position. The busbar cover is flexible to deform such that the gap expands to allow the wall to pass through the gap during attachment of the bulbar cover to the busbar holding plate and restores its original shape when passing of the wall through the gap is complete.
