Abstract:
1. A shift switching control device of a vehicle including a shift switching mechanism that electrically switches a shift position of an automatic transmission with activation of a step motor based on an operation signal indicative of an operating state of an operating device for switching a shift position of the automatic transmission, wherein if a shift position switching control gives higher priority to higher output of the step motor rather than responsiveness of switching of a shift position, a first shift switching control is provided and configured to drive the step motor in a one-two-phase excitation mode and to set a rotation speed of the step motor to a predetermined first rotation speed, and wherein if the shift position switching control gives higher priority to responsiveness of switching of a shift position rather than higher output of the step motor, a second shift switching control is provided and configured to drive the step motor in a one phase excitation mode or a two phase excitation mode and to set a rotation speed of the step motor to a predetermined second rotation speed higher than the first rotation speed.
