摘要： A continuously variable transmission is mounted on a vehicle capable of selecting plural drive modes and changes a target engine speed between drive modes. A pulley ratio is controlled by a motor. An ECU for transmission control includes a calculation section which outputs a target engine speed as a function of throttle opening and vehicle speed, and a motor control value determination section which outputs a control value for controlling the motor based on the target engine speed and an actual engine speed. In a case where, when a drive mode is selected, the current target engine speed changes by an amount exceeding a predetermined judgment value according to vehicle speed, the motor control value determination section updates the current target engine speed in a stepwise manner. The resulting configuration reduces a shift shock caused by a drive mode change.

摘要： An automatic transmission control device for a vehicle includes a gear change operation that is performed based on a throttle opening, a vehicle speed and an engine rotational speed. The automatic transmission control device also obtains a displacement of the throttle opening, determines whether the displacement falls within a predetermined range, and restricts a shift-up when the displacement exceeds the predetermined range.

摘要： An automatic transmission control device of a vehicle performs a gear change operation based on a deceleration of the vehicle. The automatic transmission control device detects the deceleration of the vehicle and an engine rotational speed. The device also stores a peak value of the engine rotation speed during a period in which a vehicle travels with one predetermined gear step, and includes a relationship map showing the relationship between the deceleration and a shift-down rotational speed. The device performs an automatic shift-down when the engine rotational speed is lowered from the peak value by a predetermined rotational speed which is obtained from the map based on the deceleration.
