Control apparatus for vehicle

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 which is disposed in the power transmission path between the engine and the electric motor and which includes a hydraulic clutch actuator that is to be controlled to switch an operation state of the clutch;
• and a hydraulic control unit configured to supply a regulated hydraulic pressure to the clutch actuator,
• the control apparatus comprising:
• an engine-start control portion configured, when the engine is to be started, to control the electric motor such that an output torque of the electric motor is increased by a magnitude corresponding to a required cranking torque that is a torque required for cranking of the engine, and to control the engine to start the engine;
• a clutch control portion configured, when the engine is to be started, to output, as a hydraulic-pressure command value for supplying the hydraulic pressure to the clutch actuator, a cranking hydraulic-pressure command value for regulating the hydraulic pressure supplied to the clutch actuator so as to cause the required cranking torque to be transmitted through the clutch, such that the outputted cranking hydraulic-pressure command value is supplied to the hydraulic control unit in an engaging process for switching of the operation state of the clutch from a released state to an engaged state;
• and
• a learning control portion configured to execute a plurality of kinds of leanings for correcting a relationship representing a correlation between the hydraulic pressure and the hydraulic-pressure command value in the engaging process,
• wherein the learning control portion is configured to set priorities for the plurality of kinds of learnings, such that at least one of the plurality of kinds of learnings is a higher priority learning to which a higher priority is given, and such that at least one of the plurality of kinds of learnings is a lower priority learning to which a lower priority is given than to the higher priority learning, and
• wherein the learning control portion is configured, when it is determined that the higher priority learning is in an unconverged state, to cause a degree of reflection of a learning result of the lower priority learning to be lower, than when it is determined that the higher priority learning is in a converged state.
