Abstract: A displayed rotation speed control apparatus for a hybrid vehicle includes: a displayed rotation speed controller having a display mode in which a target primary rotation speed stepwisely set is displayed as a driving source rotation speed in the rotation speed display device in the simulated stepwise shift mode, when the mode is switched from the EV mode to the HEV mode to initiate a starting of the engine, and when the mode is switched from the continuous shift mode to the simulated stepwise shift mode while an actual engine speed is smaller than a predetermined rotation speed, the displayed rotation speed controller being configured to display a value obtained by retarding the actual engine speed, during a period from the initiation of the starting of the engine to a rotation speed smaller than a predetermined rotation speed.

Abstract: The control method for the continuously variable transmission in the present invention detects a magnitude of an acceleration request, and when the acceleration request exceeds a preset threshold value, the control method controls a transmission ratio by switching from a first shift mode, in which a target transmission ratio is changed steplessly, to a second shift mode, which includes a stepwise change in the target transmission ratio. Then, when executing the second shift mode, a target engine rotation speed is set according to the magnitude of the acceleration request, and a step-down shift, in which the target transmission ratio is lowered stepwise according to the target engine rotation speed, is executed at an acceleration start time, and the target engine rotation speed after executing the step-down shift is retained for a predetermined period.

Abstract: In a vehicle having a continuously variable transmission, a controller selectively performs a first control mode in which a transmission ratio is controlled in a stepless manner, and a second control mode in which the transmission ratio is controlled in a stepwise manner to perform an upshift after a vehicle speed has increased. When the second control mode is selected in response to a driver's acceleration request, the controller continuously downshifts the transmission ratio until the upshift is performed.
