PROBLEM TO BE SOLVED: To satisfy passenger's air-conditioning needs while increasing opportunities of automatically stopping an engine by idling stop at a time of opening a roof.SOLUTION: By driving a blower fan 4, conditioner air passes through a heater core 10 and then blown into a cabin (heating operation). At a time of opening a roof, an idling stop condition is relaxed (to make easier to automatically stop an engine) as compared with a time of closing the roof so as to improve fuel economy. If a required blow-off temperature is equal to or higher than a predetermined value, it is prohibited to automatically stop the engine by idling stop at the time of closing the roof. On the other hand, if the required blow-off temperature is equal to or higher than the predetermined value, it is permitted to automatically stop the engine at the time of opening the roof and the conditioned air is, when the engine is automatically stopped and it is in an internal air circulation mode, controlled to be passed through the heater core 10 and to be blown into the cabin (heating operation using excess heat of the heater core 10 is executed). |
