  • Publication number: 20170284540
    Abstract: A seat belt attachment determining unit of a rough terrain vehicle determines whether or not a seat belt is being worn by a vehicle occupant. In the case it is determined by the seat belt attachment determining unit that the vehicle occupant is wearing the seat belt, the ECU switches a transmission gear stage of an automatic transmission using a first speed change mode. On the other hand, in the case it is determined by the seat belt attachment determining unit that the vehicle occupant is not wearing the seat belt, the ECU switches the transmission gear stage using a second speed change mode.

  • Publication number: 20170282924
    Abstract: A determination unit in an ECU of a rough terrain vehicle determines a reverse running state in a case that an engine rotational speed of an engine decreases when a traveling drive force is generated in the rough terrain vehicle. Further, if the determination unit determines occurrence of the reverse running state, the ECU refers to a clutch hydraulic pressure map, and sets a target hydraulic pressure so as to decrease gradually over time.

  • Publication number: 20170284485
    Abstract: A method of controlling the electric current of a linear solenoid valve by performing pulse width modulation on a coil current for energizing a linear solenoid of the linear solenoid valve to adjust the hydraulic pressure of a working oil in a hydraulic clutch for transmitting and interrupting the rotational drive power from a power source to a drive wheel of a vehicle. The method includes setting the period of the pulse width modulation to a shorter value as the degree to which the hydraulic clutch is engaged increases from a disengaged state thereof. Here, the period of the pulse width modulation may be set in accordance with the variation of a duty ratio depending on the hydraulic pressure corresponding to the degree to which the hydraulic clutch is engaged.

  • Publication number: 20170282923
    Abstract: In a rough terrain vehicle, at a time of preparing to start movement, in a case that a left paddle switch and a right paddle switch are operated together with an accelerator pedal, an ECU disengages a clutch of an automatic transmission, and causes an output of an engine to increase. On the other hand, at a time of starting movement, in a case that the left paddle switch and the right paddle switch are returned to their initial positions, the ECU engages the clutch and transmits the output of the engine from the engine to vehicle wheels via the automatic transmission, to thereby rapidly start movement of the rough terrain vehicle.

  • Patent number: 9732810
    Abstract: To allow a rider to sense torque in a low-speed traveling mode, a control device has a forward-and-reverse clutch oil pressure controller. In a low-speed traveling mode, the forward-and-reverse clutch oil pressure controller performs hunting control on driving torque, which is transmitted to a rear wheel from a crankshaft of an engine through a clutch device, a transmission, and a drive shaft, if vehicle speed stays within a second vehicle speed range for a predetermined time.

  • Patent number: 9682745
    Abstract: A saddle-type vehicle that allows common use of a handle switch with a vehicle having no advancing-backing function and can suppress increase in the number of switches and the lowering of the layout efficiency of the switches. A saddle-type vehicle has a reverse mode setting input part that sets a reverse mode in which backing driving of the saddle-type vehicle is permitted and a control system that disables shift operation of a transmission by a shift-down switch and a shift-up switch and causes the saddle-type vehicle to advance through operation of the shift-down switch and to back through operation of the shift-up switch when the reverse mode is set.
