AIR-CONDITION REMOTE CONTROL SYSTEM FOR VEHICLE

An estimated temperature range At is calculated by adding a plus-side temperature width x to the temperature D detected by a temperature sensor within the cabin of a vehicle and subtracting a minus-side temperature width y therefrom, and is displayed on the display of a mobile terminal as a temperature state of the cabin. When cooling is performed, the plus-side temperature width x is made grater than the minus-side temperature width y. Also, the plus-side temperature width x is narrowed with elapse of time from the start of pre-air-conditioning. With this operation, the temperature state of the vehicle cabin from the start of the pre-air-conditioning can be properly communicated to a vehicle user.
