Abstract: In a gear shift control unit for an automatic transmission, when an up-shift switch or a down-shift switch of a paddle shift switch is turned ON, a gear shift mode is set to a temporary manual shift mode, and a target transmission gear stage is shifted up or shifted down. Subsequently, a manual assist control is executed. In the manual assist control, an acceleration is calculated from a temporal differentiation of a vehicle speed. After it is detected that the acceleration is larger than or equal to an acceleration determination threshold, an accelerator pedal return acceleration is calculated from a double temporal differentiation of an accelerator opening degree. When the accelerator pedal return acceleration is smaller than or equal to another acceleration determination threshold, the current target transmission gear stage is automatically shifted down.

Abstract: In a vehicle shift control apparatus, a T/M_ECU has data of cancellation conditions stored therein in advance, which vary depending on modes of driving force characteristics and, in a temporary manual shift mode, selects a cancellation condition for the temporary manual shift mode which corresponds to a current mode and makes a determination as to whether the cancellation condition is satisfied. If it is determined that the cancellation condition for the temporary manual shift mode is satisfied, the T/M_ECU returns the temporary manual shift mode to the automatic shift mode.

Abstract: In a vehicle driving-force control device, when a brake switch is turned on, a transmission control unit determines a currently-selected engine mode and sets a deceleration determination value by referring to a determination-value table corresponding to the currently-selected engine mode, using a vehicle speed as a parameter. Then, the transmission control unit compares an absolute value of a deceleration with an absolute value of the deceleration determination value, and shifts down the gear stage if the absolute value of the deceleration exceeds the absolute value of the deceleration determination value.

Abstract: In a vehicle driving-force control device, if a primary speed is not lower than or equal to a kick-down allowable speed and an accelerator pedal depression amount is larger than or equal to a kick-down allowable depression amount, a shift control device identifies an intention of acceleration from a driver's accelerator operation and kick down a gear stage to a lower stage, even in a manual shift mode having been selected. In this case, the kick-down allowable speed is set to a different value for each of driving force characteristic modes, and a speed range in which a kick-down operation is allowed to be automatically performed on the basis of the primary speed is set narrower for a driving force characteristic mode having higher responsiveness to an accelerator operation.

Abstract: In a control apparatus for a continuously variable transmission, when the difference between a target transmission gear ratio calculated immediately after switching the control mode from a manual shift mode to an automatic shift mode and a current transmission gear ratio (that is, a fixed transmission gear ratio of the transmission gear stage selected in the manual shift mode immediately before the switching) is greater than or equal to a set value, a shift control unit sets a temporary target transmission gear ratio between the target transmission gear ratio and the current transmission gear ratio. If a temporary target transmission gear ratio is set, the shift control unit causes the transmission gear ratio obtained during transition of mode from the manual shift mode to the automatic shift mode to match the target transmission gear ratio stepwise via the temporary target transmission gear ratio.

Abstract: A vehicle shift control apparatus has a plurality of driving force modes in which an engine generates driving force in response to an accelerator operation, a shift control unit for controlling a transmission gear stage or a transmission ratio of an automatic transmission according to a preset shift characteristic, The apparatus sets a different shift characteristic for each of the modes upon shifting from a current transmission gear stage or transmission ratio to a target transmission gear stage or transmission ratio by means of the shift control unit, and performs a gear shift according to a currently selected shift characteristic.
