Control apparatus for vehicle

A control apparatus for a vehicle that includes (i) a drive wheel, (ii) a rotary member that is to be rotated together with the drive wheel, (iii) a power source, (iv) a power transmission apparatus configured to transmit a power from the power source toward the drive wheel, (v) a switch device configured to switch a shift position of the power transmission apparatus by operation of an electric actuator, (vi) a first power supply configured to supply an electric power for driving the electric actuator and (vii) a second power supply configured to supply the electric power for driving the electric actuator during a power-supply failure state in which the electric power is not supplied from the first power supply,

• wherein the control apparatus comprises:
• a shift control portion configured to control switching of the shift position of the power transmission apparatus between a parking position and a non-parking position that is other than the parking position, such that the rotary member is mechanically fixed and unrotatable when the power transmission apparatus is in the parking position;
• a fail-safe portion configured to execute a fail-safe operation for inhibiting the electric actuator from being re-driven, when detecting an abnormal condition of the electric actuator with drive of the electric actuator being stagnant for at least a predetermined length of time during the switching of the shift position of the power transmission apparatus between the parking position and the non-parking position;
• a power-supply control portion configured to switch a supplier of the electric power to the electric actuator, from the first power supply to the second power supply, in case of determining a power supply failure of the first power supply during the power-supply failure state;
• and
• an abnormality-detection stop portion configured, in case of occurrence of the power-supply failure state during the switching of the shift position of the power transmission apparatus from the non-parking position to the parking position, to stop the fail-safe portion from detecting the abnormal condition of the electric actuator, until the supplier of the electric power to the electric actuator has been switched to the second power supply by the power-supply control portion.
