Problems solved by technology

[0007] In the case of stopping the compressor with the air conditioner cut-off control, there is a problem that since the refrigerant cannot be compressed, the temperature of the evaporator rises, and therefore, the temperature of the blast air discharged from the air conditioner rises, deteriorating cooling performance
When the stop time of the compressor is set long while giving priority to operability, the cooling performance deteriorates and the occupants may be dissatisfied
On the contrary, for the case where the stop time of the compressor is set to be short in order to improve the cooling performance, the compressor uses the driving force of the internal combustion engine, resulting in deterioration of operability, and thus may dissatisfy the occupants

Abstract

A vehicle air conditioning control device is provided; a compressor is driven by driving force of an explosive motor in the vehicle so as to compress a freezing agent; an evaporator is configured to convert partial freezing agent into cooling air in a cooling work and used for storing residual cooling air in a cooling storage element; a control unit employs the cooling air stored in the cooling storage element to control air conditions in a vehicle compartment when the compressor stops; a refrigerating capacity calculation unit is configured to calculate a cooling air amount stored in the cooling storage element. The control unit is used for controlling the stopping of the compressor in work according to a stop condition changed corresponding to the refrigerating capacity calculated by the refrigerating capacity calculation unit.

Description

technical field [0001] The present invention relates to an air conditioner control device for a vehicle, and more particularly, to an air conditioner capable of achieving cooling performance by optimizing the stop cycle and stop time of a compressor for compressing refrigerant driven by a driving force of an internal combustion engine And operational vehicle air conditioning control device. Background technique [0002] A vehicle running with the driving force of the internal combustion engine is equipped with a vehicle air conditioning control device for controlling an air conditioning device including: a compressor for compressing refrigerant driven by the driving force of the internal combustion engine; and an evaporator for The refrigerant exchanges heat with the air discharged into the cabin, and the evaporator converts the cold air of the refrigerant into cold air to realize the cooling function. [0003] Recently, there are more and more idle-stop vehicles capable of...
