Patent number: 11685364Abstract: A vehicle controller for a vehicle including a drive source including an electric motor includes: a sense-of-beating producer configured to acquire a total required torque which is a required torque of the entire vehicle and configured to derive a total target torque corresponding to the total required torque as applied to a predetermined engine combustion cycle; and a target motor torque deriver configured to, based on the total target torque, derive a target motor torque for torque control of the electric motor. The vehicle controller controls the electric motor based on the target motor torque.Type: GrantFiled: December 16, 2020Date of Patent: June 27, 2023Assignee: KAWASAKI MOTORS, LTD.Inventors: Kyotaro Nakayama, Daisuke Yanase, Daisuke Kawai, Tomoki Tada

Patent number: 11453385Abstract: A hybrid vehicle controller is configured to: upon receiving a predetermined mode switching request, bring a clutch into a half-clutch state to start an engine using rotation of a transmission shaft; and upon determining that the engine has started, shift the clutch from the half-clutch state to a stand-by state and subsequently shift the clutch to an engaged state, the stand-by state being a state which is intermediate between the half-clutch state and a disengaged state and in which drive power of the engine is not transmitted to the transmission shaft.Type: GrantFiled: December 16, 2020Date of Patent: September 27, 2022Assignee: KAWASAKI MOTORS, LTD.Inventors: Kyotaro Nakayama, Daisuke Yanase, Daisuke Kawai, Tomoki Tada

Patent number: 11415988Abstract: 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.Type: GrantFiled: December 13, 2019Date of Patent: August 16, 2022Assignee: KAWASAKI MOTORS, LTD.Inventors: Daisuke Yanase, Daisuke Kawai, Tatsuya Hirokami, Shohei Terai, Kosuke Obayashi, Kyotaro Nakayama

Patent number: 11279341Abstract: 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 operated with a clutch disengaged and a second travel mode in which the engine is operated with the clutch engaged; 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 shock accepting condition is satisfied, sets the second travel mode as the travel mode to be executed and, upon determining that the shock accepting condition is not satisfied, prohibits the second travel mode from being set as the travel mode to be executed.Type: GrantFiled: December 13, 2019Date of Patent: March 22, 2022Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Daisuke Yanase, Daisuke Kawai, Tatsuya Hirokami, Shohei Terai, Kosuke Obayashi, Kyotaro Nakayama

Patent number: 9291085Abstract: A method of estimating an ideal air-fuel ratio in an internal combustion engine, comprises receiving an output of an upstream air-fuel ratio sensor and an output of a downstream air-fuel ratio sensor, the upstream air-fuel ratio sensor being attached to an exhaust gas passage such that it is positioned upstream of a catalyst provided in the exhaust gas passage to purify an exhaust gas, the downstream air-fuel ratio sensor being attached to the exhaust gas passage such that it is positioned downstream of the catalyst; detecting a state in which the catalyst does not store or release oxygen based on the output of the downstream air-fuel ratio sensor; and deciding as an estimated ideal air-fuel ratio in the internal combustion engine an air-fuel ratio detected by the upstream air-fuel ratio sensor when the state in which the catalyst does not store or release oxygen is detected.Type: GrantFiled: May 19, 2014Date of Patent: March 22, 2016Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Daisuke Yanase, Junji Tamura, Kouzou Suzuki, Takashi Abe, Yoshinobu Mori

Patent number: 9026340Abstract: An air-fuel ratio control system of an internal combustion engine comprises a fuel amount determiner for determining a fuel command value. The fuel amount determiner has a feedback control mode in which the fuel amount determiner determines a running state reference coefficient corresponding to a running state detected by a running state detector based on a first correspondence stored in the memory, determines a running state compensation coefficient corresponding to the running state detected by the running state detector based on a second correspondence stored in the memory, determines a feedback compensation coefficient used to cause an air-fuel ratio to reach a value closer to a theoretical air-fuel ratio based on an output of the air-fuel ratio sensor, and determines the fuel command value using a formula including the determined running state reference coefficient, the determined running state compensation coefficient, and the determined feedback compensation coefficient.Type: GrantFiled: December 23, 2011Date of Patent: May 5, 2015Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Shinichi Kuratani, Tsuyoshi Takeuchi, Kozo Suzuki, Takashi Abe, Yoshinobu Mori, Daisuke Yanase
