However, the processing device 10 notifies people and facilities around the vehicle 1 that a predetermined gas is leaking outside the vehicle 1. For example, a warning light provided on the vehicle 1 so as to be visually recognizable from the outside is controlled to light up in a predetermined lighting mode when it is specified that a predetermined gas leak has occurred. It may be a configuration or the like.

[Regarding the control method of the processing device]
An example of control performed by the processing device 10 of this embodiment will be described with reference to FIG.

The processing device 10 can realize a predetermined function by repeatedly executing a program stored in a storage area (ROM, RAM, etc.) of the processing device 10 at predetermined time intervals (for example, 10 ms intervals). The processing device 10 executes, for example, a predetermined program to perform gas leakage-related processing such as determining a destination to which the vehicle 1 is to be moved when a predetermined gas leak occurs.

As shown in FIG. 3, in the gas leakage related process (S), first, based on the gas leakage information (leakage/no leakage) acquired by the gas leakage information acquisition unit 11a, a predetermined gas is released inside the vehicle 1. It is determined whether or not there is leakage (step S01). When it is determined in step S01 that the predetermined gas is not leaking inside the vehicle 1 (N), the gas leakage-related processing is terminated (E).

When it is determined in step S01 that the predetermined gas is leaking inside the vehicle 1 (Y), the process proceeds to step S02. In step S02, the processing device 10 communicates with the information providing center 30 via the communication network 20, and the current position information of the vehicle 1 acquired by the position information obtaining unit 11c is transmitted from the processing device 10 to the information providing center 30. , and situation information (weather information and geographical information on population characteristics) corresponding to the current position information is transmitted from the information providing center 30 to the processing device 10 . Then, in the processing device 10, the gas information acquired by the gas information acquisition unit 11b, the current position information acquired by the position information acquisition unit 11c, and the situation information acquired by the situation information acquisition unit 11d are sent to the candidate site determination unit 12c. output. The candidate site determining unit 12c selects the first candidate destination for the vehicle 1 based on the geographical information relating to population characteristics among the gas information, the current position information, and the situation information, and the map database stored in the storage device 5. A ground is determined (step S02). Next, the candidate site determination unit 12c determines a second candidate site for the destination based on the weather information and the map database among the gas information, the current position information, and the situation information. Further, in the candidate route determination unit 12d, routes from the current position of the vehicle 1 to each candidate location are determined using the map database for the first candidate location and the second candidate location (step S03).

After the first candidate location, the second candidate location, and the route to each candidate location are determined in steps S02 and S03, the distance information acquisition unit 11f obtains the first distance information (current position of the vehicle 1) about the first candidate location. The distance from the position to the first candidate site) is acquired based on the map database, and the distance to the first candidate site specified based on the first distance information is within a reference range (for example, within 10 km). It is determined whether or not there is (step S04).

The distance information acquisition unit 11f may acquire, as the distance information, a linear distance on a map from the current position of the vehicle 1 to a candidate location or the like. A configuration that acquires the distance may also be used. For example, in a configuration in which the distance information acquisition unit 11f acquires a straight line distance on a map as distance information, it is possible to simplify the process of specifying the distance to the candidate site, etc. in the distance information acquisition unit 11f. In the configuration where 11f acquires the distance of the route determined by the candidate route determining unit 12d as the distance information, it is possible to identify the candidate locations and the like where the actual travel distance of the vehicle 1 is within the reference range.

If it is determined in step S04 that the distance to the first candidate site is within the reference range (Y), the process proceeds to step S05. In step S05, the first candidate location acquired by the candidate location determining unit 12c is determined as the destination by the destination determining unit 12a. Also, the route acquired by the candidate route determination unit 12d is determined as the target route by the target route determination unit 12b. Then, the notification determination unit 12e determines that a predetermined notification (gas leak notification, destination notification, target route notification) is to be performed, and the suggestion information, destination, and target that can specify that the predetermined gas leak is occurring. Information that can identify the route is output to the control unit 13 (S05).

On the other hand, if it is determined in step S04 that the distance to the first candidate site is not within the reference range (N), the process proceeds to step S06. In step S06, second distance information (the distance from the current position of the vehicle 1 to the second candidate location) is acquired by the distance information acquisition unit 11f based on the map database, and the second distance information is obtained.
