Abstract
A control apparatus for a vehicle having an electric motor, and a step-variable transmission selectively placed in a speed position with engagement of a coupling device, wherein the vehicle runs rearward with a reverse drive torque of the electric motor generated in a forward-drive low-speed position of the transmission, is provided. The control apparatus includes: a first shift control portion temporarily increasing an input torque of the transmission to raise its input speed toward a synchronizing speed in the low-speed position, and commands an engaging-side coupling device to be brought into its engaged state after the input speed has been raised to a predetermined value; and a second shift control portion increasing an engaging force of the engaging-side coupling device to bring the engaging-side coupling device into the engaged state.
