A cooling apparatus of a vehicle driving system (200) for driving a vehicle (100) according to the invention activates a heat pump (70) to cool a hybrid system by cooling medium and flows an engine cooling water in an engine water circulation passage (20) through a condenser (73) to cool the cooling medium by the engine cooling water at the condenser when an engine water circulation condition is satisfied. The engine water circulation condition is a condition that a heat pump activation condition is satisfied, and an engine cooling condition is not satisfied. The heat pump activation condition is a condition that a process of cooling the hybrid system by the cooling medium of the heat pump is requested. The engine cooling condition is a condition that a process of cooling an internal combustion engine (110) by the engine cooling water is requested.
