  • Publication number: 20230107472
    Abstract: A vehicle includes a controller configured to switch between a constant speed traveling mode in which a vehicle speed is held constant and an inertial traveling mode in which a prime mover is stopped or in an idling state, and a clutch apparatus configured to connect and disconnect power transmission between the prime mover and an output target, and the controller controls the clutch apparatus and decreases a clutch capacity so as to transit to the inertial traveling mode when detected that the vehicle is traveling on a downhill road during the constant speed traveling mode, and the controller controls the clutch apparatus and increases the clutch capacity so as to transit to the constant speed traveling mode when detected that the vehicle traveling on the downhill road has terminated.

  • Publication number: 20230095322
    Abstract: A clutch control device includes a clutch apparatus configured to connect and disconnect power transmission between an engine and a gearbox, a clutch actuator configured to output a driving force to actuate the clutch apparatus, and an ECU configured to drive the clutch actuator, and the ECU performs engine stalling avoiding control which decreases a clutch capacity when a reduction speed of an engine rotational speed becomes a predetermined threshold or more and the engine rotational speed becomes a predetermined engine stalling determination value or less.
