Therefore, if abnormal information is always obtained at the same place, the cause of the abnormal signal is not in the device itself, but in the surrounding environment (for example, a strong electric field).
It is possible to infer that they are affected by.
In addition, the information sent based on the operation of the air-conditioning diagnostic key allows the server to analyze the reason for operation, so even if the equipment itself is functioning normally, the stored data can be preset. It can be effectively used to bridge the gap between the air conditioning conditions and the feeling experienced by the occupants.

制御演算値を算出して空調制御を行う（ステップＳ
８）。If the detection signal is an abnormal value, the air-conditioning control is performed using the fail-safe value instead of the detection value (step S3). A fixed value set for each sensor is used as the fail-safe value. Then, the detection value of the sensor that has detected the abnormal value, the type of the sensor, and failure information such as the traveling location of the vehicle at that time are associated and stored in the storage unit 8 (step S4). Further, the fact that there is a failure is displayed on the display unit 7 (step S5). In this case, the display section may also display the name of the failed sensor, the installation location, and the like. In this case, it is possible to audibly appeal to the user that there is a failure from a speaker or the like not shown. Then, the fail-safe value is used for the sensor that detected the abnormal value, the detected value is used for the normal sensor, and
Air-conditioning control is performed by calculating the control calculation value (step S
8).

行う（ステップＳ８）。Even if the detected value is not an abnormal value, if the air-conditioning diagnosis key is operated (step S6), the detected value at each sensor at that time is stored (step S7). As a result, even when it is determined that the detection state of each sensor is normal, the data at that time can be stored and used in the post-processing. For example, only when the value detected by the solar radiation sensor 6 exceeds a certain value, it is possible to analyze that the air-conditioning diagnosis key is operated, and change the setting range of the sensor to a range according to the user's preference. It is possible. Then, similarly to the above, the control calculation value is calculated as usual based on the detection value of each sensor to perform the air conditioning control (step S8).

If the data contains failure information, check the relevant sensor. At this time, if the corresponding sensor is not in failure, the time when the failure information is written and the vehicle traveling location at that time are referred to. For example, if the failure information is always written when passing through a specific place, other information is collected and the sensor is not affected by the electromagnetic field from the power line. Can convey the points to the user.

を分析することもできる。The data obtained by the various sensors may be transmitted to the server at any time by using the car navigation system. According to this, it is possible to manage in real time whether or not the air conditioning in the vehicle is appropriately performed. In addition, it is not necessary to collect data manually, and it is possible not only to automatically detect a failure of a sensor or the like but also to manage the air conditioning state. For example, if there is no error in the sensor and the air conditioning diagnostic key is operated, the server side can read information such as temperature and weather at the vehicle traveling location and analyze the reason for operating the air conditioning diagnostic key.
