摘要： A control device for a continuously variable transmission includes first, second, and third controllers. The first controller controls, in response to a first speed control request for controlling a traveling speed of a vehicle for a predetermined state, a gear ratio of the continuously variable transmission such that a rotational speed of a drive power source approaches a set rotational speed. The second controller controls, in response to a second speed control request issued while the first controller is controlling the gear ratio, the gear ratio based on the rotational speed and the gear ratio. The third controller changes, when the rotational speed changes as a result of the second controller controlling the gear ratio, torque of the drive power source based on torque and the rotational speed of the drive power source before the gear ratio is changed and a target rotational speed of the drive power source.

摘要： A method of performing a shift operation in an automatic transmission with at least one form-locking shifting transmission part of a vehicle, with which, during a shift to a target gear (GZIEL), a rotational speed synchronization, between the transmission input rotational speed and the output side rotational speed, is performed. When a different rotational direction is detected between the transmission input and the transmission output, the rotational speed of the transmission input is reduced to a minimum and the target gear (GZIEL) is only shifted when the remaining rotational speed difference, between the rotational speed of the transmission input and the rotational speed of the transmission output can be at least substantially synchronized by the form-locking shift element.

摘要： A speed change system for work vehicle having a continuously variable transmission device selects a first change gear ratio which is set larger than a smallest change gear ratio, when an engine rotational speed is a first set rotational speed which is set equal or close to an idling rotational speed of an engine; retains the change gear ratio of the continuously variable transmission device at the smallest change gear ratio, when the engine rotational speed is equal to or above a second set rotational speed set on a high-speed side relative to the first set rotational speed; and makes the change gear ratio of the continuously variable transmission device larger between the first change gear ratio and the smallest change gear ratio, as the engine rotational speed at that moment becomes lower, when the engine rotational speed is between the first and second set rotational speeds.

While subject control is performed, a second engagement control unit controls the engagement pressure of the second engagement device to a mid-control set pressure that has been set to be equal to or more than a first engagement pressure and equal to or less than a second engagement pressure. The first engagement pressure is a lower limit engagement pressure capable of maintaining the second engagement device in the directly coupled engaged state, in a state in which requested torque that is torque required to be transmitted to the wheels is transmitted to the wheels. The second engagement pressure is a lower limit engagement pressure capable of maintaining the second engagement device in the directly coupled engaged state, in a state in which maximum output torque of the rotary electric machine is transmitted to the wheels.
