Abstract
A prediction element predicts a predicted arrival time at a destination based on a travel route found by a search element. In normal control mode, the first learning element learns the time period from the time point at which a vehicle is stopped, until an air-based on the predicted arrival time and the result of the learning, a control element estimates a linger period from the present moment until the passenger leaves the passenger compartment after arrival, and, based on the temperatures inside the passenger compartment and the outside as detected by first and second temperature detection element and temperature transition time information, specifies a divergence period from stopping the air-conditioning device until the temperature inside the passenger compartment leaves a comfortable temperature range. The control element stops the air-conditioning device automatically when it is decided that the linger period has become not lager than the divergence period.

12. An air conditioning control device, mounted to a vehicle, which controls the operation of an air conditioning device that regulates the temperature inside a passenger compartment comprising:
-
a first temperature detection means that detects said temperature inside the passenger compartment; a second temperature detection means that detects the temperature external to the passenger compartment of said vehicle; a prediction means that obtains a predicted arrival time of said vehicle at a destination; a storage means that stores temperature transition time information consisting of the time period required until said temperature inside the passenger compartment deviates from a predetermined comfortable temperature range, corresponding to the temperature inside the passenger compartment and the temperature external to the passenger compartment when said air conditioning device is stopped; and a control means that performs automatic stop control to stop said air conditioning device, at the time point that it is decided that said temperature inside the passenger compartment will not deviate from said comfortable temperature range even if said air conditioning device is stopped, over an interval that it is estimated that a passenger will remain within the passenger compartment of said vehicle, while taking into consideration said predicted arrival time, said temperature inside the passenger compartment, said temperature external to the passenger compartment, and said temperature transition time information. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 23, 24, 25, 26, 27, 28, 29, 30, 31)

20. An air conditioning control method employed by an air conditioning control device that is mounted to a vehicle, and that controls the operation of an air conditioning device that regulates the temperature inside a passenger compartment comprising:
-
a temperature detection process of detecting said temperature inside the passenger compartment and the temperature external to the passenger compartment of said vehicle; a prediction process, performed in parallel with said temperature detection process, of obtaining a predicted arrival time of said vehicle at a destination; and an automatic stop control process of stopping the operation of said air conditioning device, at the time point that it is decided that said temperature inside the passenger compartment will not deviate from said comfortable temperature range even if said air conditioning device is stopped, over an interval that it is estimated that a passenger will remain within the passenger compartment of said vehicle, while taking into consideration said predicted arrival time, said temperature inside the passenger compartment and said temperature external to the passenger compartment, and temperature transition time information consisting of the time period required until said temperature inside the passenger compartment deviates from a predetermined comfortable temperature range, stored in a storage means provide to said air conditioning control device, and corresponding to the temperature inside the passenger compartment and the temperature external to the passenger compartment when said air conditioning device is stopped. - View Dependent Claims (21, 22)
