Title: VEHICULAR AIR CONDITIONING CONTROL METHOD AND VEHICULAR AIR CONDITIONING DEVICE
Abstract:
The purpose of the present invention is to provide a vehicular air conditioning control method and a vehicular air conditioning device that can achieve stable deceleration when normal compressor capacity is restored from a state in which compressor capacity is suppressed during a fuel cut-off. In the present invention, regarding the control of vehicular air conditioning in which an engine is caused to output torque that meets the total value of the drive torque of a vehicle and the drive torque of an air conditioning compressor, when engine fuel is cut, the discharge capacity of the air conditioning compressor is set to a minimum capacity, and, if it has been determined to be necessary to change the discharge capacity from the minimum capacity in response to conditions in a vehicle interior, the discharge capacity is changed from the minimum capacity to an upper-limit capacity allowed during normal operation and, after a prescribed duration has elapsed since the change, the discharge capacity is changed from the upper-limit capacity to a discharge capacity corresponding to the conditions in the vehicle interior.
