  • Patent number: 10753466
    Abstract: In a transmission control device for controlling a transmission, a controller determines failure of a specific section. The controller variably controls line command pressure and secondary command pressure, and in a case where the failure is determined, fixes the line command pressure to a line pressure set value and the secondary command pressure to a secondary pressure set value. In a case where the failure is determined, the controller further starts a change in the secondary command pressure after start of a change in the line command pressure, and controls the secondary command pressure in such a manner that the secondary command pressure takes a first predetermined time to have the secondary pressure set value.

  • Patent number: 10743649
    Abstract: The plaque detecting device of the present invention comprises a light emitting unit (450) which irradiates ultraviolet or blue excitation light (L) toward the tooth surface (99a), and a first and second light receiving units (402) which receive radiated light (L?) from the tooth surface (99a). The first light receiving unit extracts the spectral component of a first wavelength region including the wavelength range of fluorescent light specific to plaque from the radiated light (L?), and obtains a first output value corresponding to the intensity of that spectral component. The second light receiving unit extracts, from the radiated light (L?), the spectral component of a second wavelength region containing the wavelength range of the fluorescent light specific to enamel and having a predetermined lower limit wavelength below the lower limit wavelength of the first wavelength region, and obtains a second output value corresponding to the intensity of this spectral component.

  • Patent number: 10704680
    Abstract: In a transmission control device for controlling a transmission, a controller determines failure of a SOL corresponding to a hydraulic secondary-pressure actuator. The controller variably controls line command pressure, and in a case where the failure is determined, fixes the line command pressure to a line pressure set value. The controller variably controls primary command pressure, and in a case where the failure is determined, continuously changes a speed ratio of a variator by variably controlling the primary command pressure. The controller variably controls secondary command pressure, and in a case where the failure is determined, fixes the secondary command pressure to a secondary pressure set value.

  • Patent number: 10677349
    Abstract: Pressure regulation valve control device has line pressure regulation valve (4) having line pressure solenoid (41) and line pressure spool valve (42) and CVT control unit (8) controlling secondary pressure (Psec) by actuating the line pressure spool valve (42) by solenoid pressure (Psol) produced by controlling current command value (I) to the line pressure solenoid (41). CVT control unit (8) has abnormality control unit (81). The abnormality control unit (81) is configured to, when decrease in secondary pressure (Psec) is detected during travel, execute, during travel, abnormality control that increases solenoid pressure (Psol), supplied to line pressure spool valve (42) from line pressure solenoid (41), more than solenoid pressure (Psol) of a time when the decrease in secondary pressure (Psec) is detected. With this, even when the decrease in the pressure is detected during travel, the decrease in the pressure is suppressed during travel while reducing influence on vehicle travel.
