Abstract
A vehicle driving apparatus includes a friction clutch, a lubricating system, and a control system. The friction clutch is disposed in a power transfer path coupling a power source of a vehicle to drive wheels of the vehicle, and controls a torque distribution ratio between the drive wheels. The lubricating system supplies oil to the friction clutch. The control system executes clutch protection control to suppress an occurrence of a slip state of the friction clutch. The control system executes the clutch protection control when a slip amount of the friction clutch becomes larger than a first threshold while the friction clutch is in a first lubricating state, and executes the clutch protection control when the slip amount of the friction clutch becomes larger than a second threshold while the friction clutch is in a second lubricating state.
