Claim Text:
1. A control device of a vehicle comprising a cooling device, the cooling device including a compressor for compressing refrigerant, a condenser for cooling the compressed refrigerant, an evaporator for cooling by vaporizing the cooled refrigerant, and an air-conditioner outlet port, the control device comprising a processor configured to: (i) calculate a target air-conditioner outlet port temperature (TAO) that is necessary to achieve a set or desired temperature within a predetermined time period under current conditions inside and/or outside of a passenger compartment of the vehicle; (ii) compute, based on the TAO, a first transition curve over the predetermined time period, the first transition curve being computed so that a temperature of the evaporator transitions to a target evaporator temperature that is necessary for obtaining the TAO; (iii) compute, based on the current conditions, a second transition curve showing an estimated transition of the of the temperature of the evaporator over the predetermined time period under the current conditions; (iv) compare the first transition curve showing the transition to the target evaporator temperature over the predetermined time period with the second transition curve showing the estimate evaporator temperature transition over the predetermined time period; and (v) if it is determined that the first transition curve becomes less than the second transition curve over the predetermined time period, execute a cooling capacity increase control.
