According to a cooling device of a vehicle driving system of the present invention, if an engine cooling condition, in which the process of cooling an internal combustion engine by an engine coolant is required, is satisfied, the engine coolant is circulated to engine circulation passages to pass an engine radiator such that the internal combustion engine is cooled by the engine coolant. Furthermore, according to the cooling device of the present invention, if a heat pump operation condition, in which a process of cooling a hybrid system by a refrigerant of a heat pump is required, is satisfied, the heat pump is operated to cool the hybrid system by the refrigerant. In addition, according to the cooling device of the present invention, if an engine circulation condition, in which the heat pump operation condition is satisfied and the engine cooling condition is not satisfied, is satisfied, the heat pump is operated to cool the hybrid system by the refrigerant while the engine coolant is circulated to the engine circulation passages to pass a condenser of the heat pump, thereby cooling the refrigerant by the condenser.

    본 발명에 관련된 차량 구동 시스템의 냉각 장치는, 기관 냉각수에 의해서 내연 기관을 냉각하는 처리가 요구되었다는 기관 냉각 조건이 성립된 경우, 기관 라디에이터를 통과하도록 기관 냉각수를 기관 순환 수로로 순환시킴으로써 기관 냉각수에 의해서 내연 기관을 냉각한다. 또, 본 냉각 장치는, 히트 펌프의 냉매에 의해서 하이브리드 시스템을 냉각하는 처리가 요구되었다는 히트 펌프 작동 조건이 성립된 경우, 히트 펌프를 작동시켜 냉매에 의해서 하이브리드 시스템을 냉각한다. 또한, 본 냉각 장치는, 히트 펌프 작동 조건이 성립되어 있고 또한 기관 냉각 조건이 성립되어 있지 않다는 기관 순환 조건이 성립된 경우, 히트 펌프를 작동시켜 냉매에 의해 하이브리드 시스템을 냉각함과 함께 히트 펌프의 응축기를 통과하도록 기관 냉각수를 기관 순환 수로로 순환시킴으로써 응축기에 의해 냉매를 냉각한다.
