Abstract:
This system for cooling a power control device (10) of a hybrid automobile (C) provided with an engine (1) and a motor/generator (2) is provided with: cooling devices (20, 40) that cool the power control device (10); an electronic control device (15) that controls the cooling devices (20, 40); and an intake air temperature sensor (36) that detects the intake air temperature (Tint) and is provided to the air intake pathway (50) of the engine (1). The electronic control device (15) is configured in a manner so as to determine whether or not the automobile (C) is in a baseline driving state such that the amount of intake air to the engine (1) is secured at or above a baseline intake air quantity, when the automobile (C) has been determined to be in the baseline driving state, to determine the presence/absence of an abnormality of the cooling devices (20, 40) using the intake air temperature (Tint) detected by the intake air temperature sensor (36), and when the automobile (C) has been determined not to be in the baseline driving state, not to determine the presence/absence of an abnormality of the cooling devices (20, 40).
