    摘要： A continuously variable transmission includes a variator (20) capable of varying a speed ratio continuously, and a subtransmission mechanism (30) provided in series with the variator (20). When an actual through speed ratio passes a predetermined mode switch speed ratio, a transmission controller (12) performs a coordinated shift in which a gear position of the subtransmission mechanism (30) is changed and a speed ratio of the variator (20) is varied in an opposite direction to a speed ratio variation direction of the subtransmission mechanism (30). When the rapid deceleration is determined to be underway, the transmission controller (12) decreases a speed ratio variation amount of the variator (20) in the direction of a High side accompanied by a downshift of the subtransmission mechanism (30) compared with the coordinated shift.

    摘要： In an engine output control apparatus of a power train employing an engine and an automatic transmission, capable of executing engine output control for excessive torque input prevention engine torque limiting action and for a shift speed control of the transmission, at least two different kinds of engine output control systems having control characteristics differing from each other, are provided. A controller selectively uses these engine output control systems depending on a power-train operating condition, such that a first one of the engine output control systems having a superior transient response is used for the engine output control for shift response control during shifting, and that a second one of the engine output control systems having a superior steady-state stability is used for the engine output control for excessive torque input prevention engine torque limiting action during non-shifting.

    摘要： A continuously variable transmission 4 for a vehicle includes a variator 20 that modifies a speed ratio continuously and a subtransmission mechanism 30 that is connected in series to the variator 20 and applies a first speed and a second speed, which is higher than the first speed, selectively. When the vehicle is running under a low load/high speed upshift condition having a lower load or a higher speed than a normal upshift condition, the subtransmission mechanism 30 is upshifted from the first speed to the second speed at a lower vehicle speed than under the normal upshift condition, and as a result, both rotation variation in an internal combustion engine 1 accompanying upshifting of the subtransmission mechanism 30 and an increase in a fuel consumption amount of the internal combustion engine 1 due to the shift operation in the continuously variable transmission 4 are suppressed.

    摘要： A continuously variable transmission (4) includes a variator (20) capable of varying a speed ratio continuously, and a subtransmission mechanism (30) provided in series with the variator (20). On the basis of an operating condition of a vehicle, a transmission controller (12) sets a destination through speed ratio (DRatio), which is an overall speed ratio of the variator (20) and the subtransmission mechanism (30) to be realized in accordance with the operating condition, and controls the variator (20) and the subtransmission mechanism (30) on the basis thereof. When shifts are prohibited in the subtransmission mechanism (30), the destination through speed ratio (DRatio) is limited to a speed ratio range that can be realized only by a shift in the variator (20).
