other Embodiment approach

[0151] In the first and second embodiments described above, in the pre-air conditioning control, the pre-air conditioning operation mode is started based on both the difference between the internal air temperature Tr and the external air temperature Tam and the rate of change of the difference, but the present invention is not limited thereto. , either side can also be used.

[0152] In addition, in the above-mentioned first and second embodiments, a case has been described in which the pre-air conditioning target temperature is changed in accordance with the priority set by the occupant in step S190 when a negative determination is made in the determination of step S180, However, if the occupant presets the suspension of the pre-air conditioning as a priority, then in step S190, the control to suspend the pre-air conditioning is performed, and the air conditioning control ends here.

[0153] In addition, in the second embodiment, the information items input from the cloud ser...

Abstract

This vehicular air-conditioning device is capable of executing pre-conditioning for initiating air-conditioning in a passenger compartment before an occupant enters the vehicle and is provided with a pre-conditioning control part (218). The pre-conditioning control part is capable of setting: a pre-conditioning blowing operation mode wherein a blower (130) is operated while operation of a compressor (141) is prohibited, the introduction mode is set to an outside air introduction mode, the output of the blower (130) is set to maximum, and furthermore a face-foot mode is set as the blowing mode; and a pre-conditioning operation mode wherein the blower (130) and compressor (141) are operated, and the blower (130), compressor (141), introduction mode, and blowing mode are automatically set in accordance with a target blowing temperature (TAO). When executing pre-conditioning, the vehicular air-conditioning device executes the pre-conditioning blowing operation mode before executing the pre-conditioning operation mode and starts executing the pre-conditioning operation mode on the basis of the difference between the inside temperature (Tr) in the passenger compartment and the ambient temperature (Tam) outside the vehicle and / or the rate of change in the difference.

Description

[0001] Cross-references to related applications [0002] This application is based on the JP Patent application 2014-256566 for which it applied on December 18, 2014, The indication content is incorporated in this application by reference. technical field [0003] The present invention relates to a vehicle air conditioner capable of implementing pre-air conditioning that starts air conditioning in the vehicle interior before occupants get into the vehicle. Background technique [0004] As a conventional vehicle air conditioner capable of performing pre-air conditioning, for example, the vehicle air conditioner described in Patent Document 1 is known. In the vehicle air conditioner disclosed in Patent Document 1, there are a pre-air-conditioning operation mode and a pre-blowing operation mode as operation modes for pre-air-conditioning. To operate, in the above-mentioned pre-blowing operation mode, the air blower is operated, the operation of the compressor is prohibited, an...
