In addition, the air conditioner 23 may be configured to sequentially execute the processing in each step shown in FIG. 3 in a state where the switch for instructing execution of the inside air circulation mode is turned on.

  First, at step S10, the air conditioning ECU 22 determines whether or not the own vehicle is a succeeding vehicle in which a formation automatic traveling is being performed. This determination process is performed based on the driving information of the own vehicle acquired from the vehicle ECU 20. If it is determined in step S10 that the vehicle is not a succeeding vehicle, the process returns to step S10 again, and the determination process of step S10 is repeated until it is determined that the vehicle is a following vehicle.

  If it is determined in step S10 that the vehicle is a succeeding vehicle, then it is determined in step S20 whether the current air intake mode is the inside air circulation mode. Since the vehicle in this state is a succeeding vehicle during formation automatic traveling, the exhaust gas discharged from the preceding vehicle is easily intruded into the vehicle interior from the outside air intake of the following vehicle 2 or the like. If the air conditioning ECU 22 is currently in the inside air circulation mode, the exhaust gas does not intrude into the vehicle compartment, so the process returns to step S10 and executes the determination process of step S10. At the time of the mode such as the outside air intake mode or the inside / outside air introduction mode in which the outside air is being sucked, the air conditioning ECU 22 is in a state where the exhaust gas can intrude into the vehicle compartment. The process returns to step S10 again to execute the determination process of step S10. In step S30, the air conditioning ECU 22 controls the position of the inside / outside air switching door 230 to switch the open / close state of the air intake, and executes a process of changing to a mode in which outside air is not sucked, for example, the inside air circulation mode. As a result, outside air is not taken into the vehicle compartment in the succeeding vehicle 2 in which the row automatic traveling is being carried out, so the deterioration of the vehicle interior environment due to the exhaust gas of the preceding vehicle 1 traveling immediately before being mixed into the vehicle cabin can be prevented. .

  The effects brought about by the vehicle air conditioner of the first embodiment will be described. The air conditioner for vehicles is the air conditioner 23 mounted in the following vehicle 2 which can carry out formation automatic travel which automatically travels immediately after the preceding vehicle 1. The air conditioning system for a vehicle prohibits the outside air suction mode for sucking outside air into the vehicle compartment when the group automatic travel is carried out, and carries out the outside air suction suppression mode for circulating air in the vehicle room. Do.

  According to the vehicle air conditioner, the outside air suction suppression mode is implemented, which is an inside air circulation mode in which the outside air around the vehicle is not taken into the vehicle compartment. This makes it possible to prevent the exhaust gas discharged from the leading vehicle 1 from being taken into the passenger compartment of the following vehicle 2 together with the outside air during formation automatic traveling. Therefore, it is possible to provide a vehicular air-conditioning system capable of suppressing the exhaust gas discharged from the leading vehicle 1 from intruding into the following vehicle 2 while carrying out the formation automatic traveling.
