Abstract
In response to the driver's gearshift operation from a parking position to a drive position, the control procedure of the invention controls a motor connected to a transmission to output a center adjustment torque Tset, while the transmission is in a state of disconnecting the motor from an axle of a hybrid vehicle. The control procedure adjusts the rotation centers of respective rotational elements in the transmission by rotating the respective rotational elements, and then initiates gradual engagement of a brake to set the transmission in a low gear position. This arrangement desirably retains deviation of the rotation centers of the respective rotational elements in the transmission and prevents potential troubles due to the eccentric rotation centers of the respective rotational elements in the transmission.
