1. A control apparatus for a vehicle that includes: an engine; drive wheels; an electric motor connected to a power transmission path between the engine and the drive wheels, in a power transmittable manner; a clutch disposed between the engine and the electric motor in the power transmission path; and a hydraulic control unit configured to supply a regulated hydraulic pressure that is to be used for switching an operation state of the clutch,
the control apparatus comprising:
a clutch control portion that is configured, when the engine is to be started, to output a packing hydraulic-pressure command value and a cranking hydraulic-pressure command value that is higher than the packing hydraulic-pressure command value, such that the packing hydraulic-pressure command value is outputted to the hydraulic control unit, for regulating the hydraulic pressure so as to place the clutch in a pack-clearance-elimination completion state in which a pack clearance of the clutch has been eliminated, in a process of switching of the operation state of the clutch from a released state to an engaged state, and such that the cranking hydraulic-pressure command value is outputted to the hydraulic control unit, after elapse of a predetermined time required to place the clutch in the pack-clearance-elimination completion state, for regulating the hydraulic pressure so as to cause the clutch to transmit a cranking torque required by a cranking by which a rotational speed of the engine is increased, and
an engine-start control portion that is configured, when the engine is to be started, to control the electric motor for causing the electric motor to output the cranking torque, and to control the engine for starting the engine,
wherein the clutch control portion is configured, in a case in which it is determined that the cranking is required by a request requesting an increase of a power performance of the vehicle during output of the packing hydraulic-pressure command value, to output the cranking hydraulic-pressure command value in place of the packing hydraulic-pressure command value even before the elapse of the predetermined time.
