Abstract: An apparatus, applied to a vehicle having an internal combustion engine and an electric motor as power sources, comprises a changeover mechanism which is able to change a connection state of an electric motor output shaft to any one of “an IN-Connection State” in which a power transmission path is provided between a transmission input shaft and the electric motor output shaft, “an OUT-Connection State” in which a power transmission path is provided between the transmission output shaft and the electric motor output shaft, and “a neutral state” in which no transmission path therebetween is provided. When a changeover condition is satisfied, a period is provided in which a sum Ts of an internal-combustion-engine-side-output-torque Te and an electric-motor-side-output-torque Tm coincides with a required driving torque Tr, and an electric motor torque continues to be zero.

Abstract: A transmission includes a controller being provided with a change-speed stage anticipator. The controller adopts a time, which one of the transmission's gear-mechanism selectors requires in shifting a current change-speed stage to another change-speed stage, as a pre-shift time for selecting the latter change-speed stage. The change-speed stage anticipator operates the one of the gear-mechanism selectors while adopting a temporary change-speed stage as a subsequent change-speed stage when the temporary change-speed stage, which is estimated from a state of vehicle after the pre-shift time, the state of vehicle being relevant to each element of an anticipated change-speed stage group that is made up of one or more of the change-speed stages that can be selected by the one of the gear-mechanism selectors being set on one of the transmission's input shafts that is disconnected from a power source, coincides with an anticipated change-speed stage that corresponds to the pre-shift time.

Abstract: An apparatus comprises a changeover mechanism which is able to change a connection state of an electric motor output shaft to any one from alternatives consisting of “an IN-Connection State” in which a power transmission path is provided between a transmission input shaft and the electric motor output shaft, “an OUT-Connection State” in which a power transmission path is provided between the transmission output shaft and the electric motor output shaft, and “a neutral connection state” in which no transmission path therebetween is provided. The changeover is carried out based on a combination (area) of a vehicle speed V and a required driving torque T. As for the changeover, an (first, second) IN-connection area is more enlarged and the OUT-Connection area and the neutral connection area are more narrowed, as a temperature of a lubricating oil is lower.

When a kick-down-condition is satisfied, a changeover operation for changing an electric motor connection state to the OUT-Connection State is firstly performed. Thereafter, a gear position shifting operation for increasing a transmission reduction ratio is performed. After the kick-down-condition satisfied, an E/G side output torque Te and a M/G side output torque Tm is adjusted in such a manner that a sum Ts of Te and Tm continues to increase.

Abstract: A transmission includes a controller that has a rapid-deceleration judge and a rapid-deceleration processor. The rapid-deceleration judge judges whether a vehicle is decelerating rapidly or not. The rapid-deceleration processor includes a torque-fluctuation inhibitor, and an after-rapid-deceleration change-speed stage anticipator. The torque-fluctuation inhibitor shuts off power transmission from a power source, or holds power transmission by way of a current change-speed stage or lower, when the vehicle is decelerating rapidly. The after-rapid-deceleration change-speed stage anticipator anticipates a subsequent change-speed stage being adapted for restarting or reaccelerating the vehicle that has come out of rapid deceleration.

Abstract: An apparatus comprises a changeover mechanism which is able to change a connection state to any one of three states, i.e., “an IN-Connection State” in which a power transmission path is provided between a transmission input shaft and the electric motor output shaft, “an OUT-Connection State” in which a power transmission path is provided between a transmission output shaft and the electric motor output shaft, and “a neutral connection state” in which no transmission path therebetween is provided. At a timing (time t1) at which a both-neutral-state is required during the vehicle is running, both “an operation for a changeover of the state-of-connecting of the clutch mechanism (C/T 30) from a connection-state to a shut-off-state” and “an operation for a changeover of said connection state of the changeover mechanism 50 from either one of the IN-Connection State and the OUT-Connection State to the non-connection state” are simultaneously started.
