    Abstract: A gas tank liner comprises: a cylindrical section formed using a first resin; and a dome section formed using a second resin, the dome section being arranged at each axially opposite end of the cylindrical section, wherein either one of the first resin or the second resin has a higher linear expansion coefficient and higher yield strain than the other, the yield strain being the threshold of strain that, when met, makes the first resin or the second resin incapable of restoring its original state if the first resin or the second resin strains and yields in response to the application of external force.

  • Publication number: 20180202374
    Abstract: An electronic control unit is configured to select a first cam as a driving cam of an intake valve in a first operation range where a target value of an EGR rate is set to a specified EGR rate, and is configured to select a second cam as the driving cam in a second operation range smaller in valve duration and lift amount than the first cam. Accordingly, in most of the operation regions, the first cam is selected, and the second cam is selected only in a high-torque and high-speed region. When the second cam is selected in the high-torque and high-speed region, the state where an actual compression ratio is high can be eliminated, and suction efficiency can be decreased. Therefore, decrease in a knocking limit can be suppressed.

    Abstract: A control apparatus for a vehicle, which is provided with an engine and drive wheels, is configured, during an inertia running or stop of the vehicle, to execute a control for stopping the engine and/or disconnecting the engine from the drive wheels in each area, depending on whether a condition is satisfied or not. The condition is set based on an information transferred from other vehicle in which the control is executable during an inertia running or stop of the other vehicle. The information includes (a) a location information indicative of the each area and (b) an acceleration representative value representing a required acceleration of the other vehicle required by an operator of the other vehicle in the each area. The acceleration representative value is associated with the location information indicative of the each area.

  • Publication number: 20180201307
    Abstract: When a steering intervention of the driver is performed during automated steering control, a driver assistance system for a vehicle determines a P control amount based on a non-linear characteristics and calculates an I control amount using a coefficient according to a characteristics (solid line). In an angle difference range R1, the P control amount based on the non-linear characteristics is determined such that the amount of increase of absolute value of the P control amount with respect to the amount of increase of absolute value of the angle difference becomes smaller as compared to a linear characteristics. The coefficient with the characteristics (solid line) indicates 1 in the angle difference range R1, and approaches zero when the absolute value of the angle difference is greater in an angle difference range R2. To calculate the I control amount, the coefficient is multiplied by the current value of the angle difference.

  • Publication number: 20180205100
    Abstract: When a shut-off valve is opened, gas is discharged via a main passage which is disposed at a predetermined height from a bottom of a gas-liquid separator. Water which gathers in the bottom of the gas-liquid separator flows from a bypass passage to the main passage and is discharged when water level difference>height is satisfied. When water which gathers in the bottom of the gas-liquid separator is supercooled water, discharge of water is avoided by controlling an open pressure and a passage pressure such that water level difference<height is satisfied.
