  • Patent number: 11685364
    Abstract: 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.

  • Patent number: 11453385
    Abstract: 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.

  • Patent number: 11415988
    Abstract: 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.

  • Publication number: 20220203957
    Abstract: A moving machine control program causes a computer to execute: acquiring requested external force regarding an actuator; reading out a reference kinetic model that defines moving machine behavior exhibited when the actuator generates external force corresponding to the requested external force; calculating, as requested moving machine behavior, the moving machine behavior exhibited when the actuator generates the external force corresponding to the requested external force, in accordance with the reference kinetic model; measuring actual moving machine behavior during traveling of the moving machine; correcting the requested external force such that the actual moving machine behavior measured in the measuring step approaches the requested moving machine behavior calculated in the calculating step; and controlling the actuator based on the corrected requested external force.

  • Patent number: 11279341
    Abstract: 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.
