  • Patent number: 10913332
    Abstract: In a heat exchange unit, a shutter device is disposed on a vehicle front side with respect to a coolant heat exchanger to open and close a passage for traveling air directed toward the coolant heat exchanger. A blower is switchable between a first blowing state in which air flows from the vehicle front side to the vehicle rear side and a second blowing state in which air flows from the vehicle rear side to the vehicle front side. In a case where a switch that makes a vehicle travelable is in an on state, a control unit switches the blower to the second blowing state, while an open degree of the shutter device is set at a closing side from a maximum open degree of the shutter device when a temperature of the engine coolant is equal to or lower than a predetermined temperature determination value.

  • Publication number: 20200369120
    Abstract: A detector detects physical quantities relating to an operation of a vehicle air-conditioning device at a predetermined sampling frequency to generate groups of time-series data items. A volatile tracking memory has a work area to which the groups of time-series data items for a tracking period is writable. A record holding power accumulator supplies, to the tracking memory, power used for holding in the work area the groups of time-series data items. A writer sequentially overwrites the groups of time-series data to the work area of the tracking memory and stops overwriting of the groups of time-series data items to the work area when an abnormality occurs in the vehicle air-conditioning device.
