  • Patent number: 10718386
    Abstract: A basic pulse time setting section determines a basic pulse time for initial invalid stroke elimination by applying current values of oil temperature and throttle opening to the basic pulse time map. A subtraction time setting section determines a subtraction time by applying current values of oil temperature and clutch oil pressure to the subtraction time map. A pulse time determining section determines a predetermined initial invalid stroke elimination pulse time by subtracting the subtraction time from the basic pulse time. An initial invalid stroke elimination permission/inhibition determination section, at a starting timing of initial invalid stroke elimination, inhibits this-time initial invalid stroke elimination if the elapsed time from the execution timing of the preceding initial invalid stroke elimination is within the predetermined inhibition period.

  • Patent number: 10655732
    Abstract: A gear position detecting device includes a rotation angle sensor for detecting a turn position of a shift drum and a position sensor for detecting that the shift drum is at a neutral position. The rotation angle sensor is a volume sensor that linearly increases or decreases an output voltage according to a turning motion of the shift drum. The neutral position is set in such a way as not to overlap a dead zone. It is determined according to an output signal of the rotation angle sensor and an output signal of the position sensor whether the shift drum is at a reverse gear position located between the neutral position and the dead zone or a fifth gear position turned by 360 degrees from the reverse gear position. Such detecting device detects a gear position with a high accuracy even if the number of gear positions are increased.

  • Patent number: 10569756
    Abstract: A driving force control device for saddled vehicle includes a transmission that transmits driving force of an engine to a driving wheel of a vehicle at predetermined reduction ratio; a clutch that connects/disconnects the driving force between the engine and the transmission; and a controller that controls the transmission and the clutch. The controller permits selection of a normal mode in which the reduction ratio of the transmission is varied according to a running condition and a slow mode permitting slow forward movement and slow backward movement by varying the reduction ratio of the transmission to a fixed reduction ratio according to predetermined operation, and the controller holds the clutch in a partial clutch engagement condition so as to prevent the vehicle from moving forward or backward when the slow mode is selected and no predetermined operation is performed.

  • Patent number: 10562393
    Abstract: A basic clutch capacity calculating unit calculates a clutch capacity of the DCT applying an engine speed, a degree of throttle opening, and a front wheel vehicle speed to a map. The basic clutch capacity calculating unit further calculates the DCT basic clutch capacity by amending the basic clutch capacity based on an oil temperature and a water temperature. An NE converted value calculating unit calculates an NE converted value obtained by converting a vehicle speed into an engine speed with the front wheel vehicle speed and a DCT speed change stage as input parameters. A hunting detecting unit detects hunting by comparing the engine speed with the NE converted value when a throttle operation is detected. A DCT clutch capacity correcting unit makes decreasing correction of a DCT clutch capacity when hunting is detected for suppressing the hunting.
