Patent number: 11904835Abstract: A hybrid vehicle includes: a driving power source including an engine and an electric motor; a battery that supplies electric power to the electric motor; and a controller that controls the engine and the electric motor according to a temperature of the battery. When a predetermined EV mode condition is satisfied, and a normal-temperature condition in which the temperature of the battery is a threshold or more is satisfied, the controller controls the driving power source in an EV mode in which the electric motor is driven. When the EV mode condition is satisfied, and a low-temperature condition in which the temperature of the battery is less than the threshold is satisfied, the controller operates the electric motor in a state where electric current flows between the battery and the electric motor drives the engine such that the engine generates traveling power transmitted to a driving wheel.Type: GrantFiled: November 29, 2021Date of Patent: February 20, 2024Assignee: KAWASAKI MOTORS, LTD.Inventors: Tomoki Tada, Shohei Terai

Patent number: 11897332Abstract: A wheelie suppressing control unit includes: a first determiner that determines whether a vehicle is in a traveling state satisfying a first condition representing a wheelie state; a second determiner that determines whether the vehicle is in a traveling state satisfying a second condition representing a pre-wheelie state which is a state preceding the wheelie state; and a controller that controls the vehicle based on an operation input. If the first determiner determines that the first condition is satisfied, the controller executes first control that reduces the output of a drive source of the vehicle. If the first determiner determines that the first condition is not satisfied and the second determiner determines that the second condition is satisfied, the controller executes second control that restricts a rate of change of the output with respect to the operation input provided to an operation member.Type: GrantFiled: August 18, 2020Date of Patent: February 13, 2024Assignee: KAWASAKI MOTORS, LTD.Inventor: Shohei Terai

Patent number: 11529943Abstract: A quickshifter-equipped vehicle control unit includes an engine speed calculator configured to calculate an engine speed and a shift controller configured to operate in a quick shift mode and in a normal shift mode. The quick shift mode is a mode in which upon detection of the shift operation, the shift controller adjusts an output of an engine while keeping a main clutch in an engaged state, and the normal shift mode is a mode in which upon detection of the shift operation, the shift controller controls a clutch actuator to bring the main clutch into a disengaged state. The shift controller selects the quick shift mode when the engine speed is higher than a predetermined rotational speed threshold, and selects the normal shift mode when the engine speed is lower than the rotational speed threshold.Type: GrantFiled: August 24, 2020Date of Patent: December 20, 2022Assignee: KAWASAKI MOTORS, LTD.Inventors: Shohei Terai, Yuuka Matsumoto
