  • Publication number: 20200192369
    Abstract: A control apparatus of a hybrid leaning vehicle includes: a travel mode request section that requests one travel mode selected from a plurality of travel modes including a first travel mode in which an engine is stopped and an electric motor is operated and a second travel mode in which the engine is operated; and a travel mode setting section. When the travel mode request section requests the second travel mode during travel in the first travel mode, the travel mode setting section, upon determining that a steady turning condition is satisfied, sets the second travel mode as the travel mode to be executed and, upon determining that the steady turning condition is not satisfied, prohibits the second travel mode from being set as the travel mode to be executed.

    Abstract: In a gas sensor element, an electrolyte layer has a solid electrolyte body having oxygen ionic conductivity. A first insulation body is stacked at a first surface side of the electrolyte layer. A second insulation body is stacked at a second surface side of the electrolyte layer. A measurement gas chamber is surrounded by the electrolyte layer and the first insulation body, into which a detection target gas is introduced. A reference gas chamber is surrounded by the electrolyte layer and the second insulation body, into which a reference gas is introduced. A heater is embedded in the first insulation body. The second insulation body has a low thermal conductivity part having a thermal conductivity which is lower than a thermal conductivity of a heater embedded part formed in the first insulation body in which the heater is embedded.

  • Publication number: 20190391109
    Abstract: A gas sensor is equipped with a sensor device made of a stack of a solid electrolyte body, a sensor electrode, a reference electrode, a first insulator, a second insulator, a gas chamber, a reference gas duct, a heater, and a heat transfer member. The heater has a heating element at least partially overlapping the sensor electrode and the reference electrode. The heat transfer member is made of a dense metallic oxide material which blocks passage of measurement gas therethrough. The heat transfer member is held between the sensor electrode and the first insulator in which the heater is embedded within the gas chamber and works to facilitate transfer of thermal energy, as generated by the heater, to the solid electrolyte body, the sensor electrode, and the reference electrode. This results in enhanced thermal conductivity of the sensor device and achieves quick activation of the sensor device.

  • Patent number: 10330469
    Abstract: A bank angle detection device for a motorcycle includes a bank angle estimator configured to estimate a moving body bank angle ?b and a correcting section configured to estimate a vehicle body bank angle ?f. The bank angle estimator estimates the moving body bank angle ?b that is a gradient of a moving body axial line A1, on the basis of a balance state where a centrifugal force CF acting on a moving body and a gravitational force GF acting on the moving body during cornering are in balance with each other. The correcting section corrects the moving body bank angle ?b on the basis of an inertia force about a longitudinal axis acting on a vehicle body, so as to estimate the vehicle body bank angle ?f that is a gradient of a center of gravity G of the vehicle body with respect to a vertical line.

  • Patent number: 9694713
    Abstract: An electric motorcycle includes an electric motor, a manual transmission, a shift drum potentiometer, and an ECU. When it is determined based on an input from the shift drum potentiometer that a transmission manipulation has been performed, the ECU executes a first control operation when switching from a power transmission state to a power cut state and executes a second control operation when returning from the power cut state to the power transmission state. In the first control operation, the ECU controls an operation of the electric motor to facilitate disengagement of an engagement mechanism from a gear train of the manual transmission. In the second control operation, for facilitating engagement of the engagement mechanism with a different gear train, the ECU controls the operation of the electric motor to make a revolving speed of the different gear train close to the revolving speed of the engagement mechanism.
