Publication number: 20170284540Abstract: 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.Type: ApplicationFiled: March 31, 2017Publication date: October 5, 2017Applicant: HONDA MOTOR CO., LTD.Inventors: Naoki Sakamoto, Dustin Williams

Publication number: 20170282924Abstract: 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.Type: ApplicationFiled: March 30, 2017Publication date: October 5, 2017Applicant: HONDA MOTOR CO., LTD.Inventor: Naoki Sakamoto

Publication number: 20170284485Abstract: 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.Type: ApplicationFiled: March 3, 2017Publication date: October 5, 2017Inventors: Kosuke Tsunashima, Toshimitsu Nakajima, Naoki Sakamoto

Publication number: 20170282923Abstract: 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.Type: ApplicationFiled: March 30, 2017Publication date: October 5, 2017Applicant: HONDA MOTOR CO., LTDInventors: Naoki Sakamoto, Yasuhiro Nozaki, Naoki Kobayashi, Dai Arai, Takao Kochi
