- This search control flow is executed repeatedly while the autonomous driving device 1 is running. Note that each "S" in this search control flow represents multiple steps executed by multiple commands included in the search control program.
- the search block 110 acquires hazard information.
- Hazard information is information that indicates the occurrence of a hazard. Therefore, the driving area A to which the hazard information applies is an area in which the occurrence of a hazard is predicted.
- the search block 110 acquires the hazard information, for example, from the remote center 2 via the communication system 20. Alternatively, the search block 110 may acquire the hazard information by determining the occurrence of a hazard based on information acquired from its own external sensor 11 and internal sensor 12.
- the search block 110 determines whether communication with the remote center 2 is possible.
- the search block 110 determines whether communication with the remote center 2 is possible by performing a fault diagnosis of the wide-area communication type communication system 20 and attempting communication with the remote center 2. If it is determined that communication is not possible, this flow ends.
- the autonomous mobile device 1 waits for a search from an autonomous mobile device 1 in an active state that can communicate with the remote center 2 (described below) as an autonomous mobile device 1 in a disconnected state.

Note that, if the disconnected device can use a short-range communication type communication system 20, it may transmit a signal to the surrounding area by short-range communication to assist the search by the active device.
- the search block 110 determines whether the autonomous driving device 1 is capable of driving.
- the search block 110 may determine whether it is capable of driving by, for example, performing a fault diagnosis of the sensor system 10 or the driving system 40. If it is determined that driving is not possible, the flow proceeds to S130.
- the transmission block 120 transmits a fault notification to the remote center 2 via the communication system 20 notifying that driving is not possible, and then ends the flow. Note that even if it is determined that driving is not possible, the autonomous driving device 1 may transmit observation information (described later) around the current stopping position to the remote center 2 as long as the external sensor 11 is available.
- the search block 110 determines the search mode of the autonomous driving device 1. For example, the search block 110 determines the search mode by obtaining a mode designation command from the remote center 2. Search modes include, for example, an area search mode and a disrupted device search mode. If the mode is determined to be the area search mode, the flow proceeds to S150. If the mode is determined to be the disrupted device search mode, the flow proceeds to S160.
- the autonomous driving device 1 When executing the area search mode at S150, the autonomous driving device 1 searches for facilities that make up the driving area A and transmits the search results to the remote center 2.
- the detailed processing at S150 will be explained below with reference to the flowchart in FIG. 6.
- the search block 110 acquires external environment information for the travel area A after the hazard. More specifically, the search block 110 drives the autonomous driving device 1 near a location in the travel area A where observation information, described below, has not yet been acquired, and acquires external environment information for that location from the external environment sensor 11. At this time, the search block 110 may, for example, drive the autonomous driving device 1 so as to trace the location where external environment information was acquired before the hazard occurred. Alternatively, the search block 110 may drive the autonomous driving device 1 so as to continue proceeding along the planned travel route before the hazard occurred. Alternatively, the search block 110 may drive the autonomous driving device 1 so as to proceed along the planned travel route distributed from the remote center 2 after the hazard occurred. The search block 110 acquires the external environment information by linking it to the position information of the location.
- the search block 110 acquires pre-hazard external world information relating to the location for which the external world information was acquired in S151.
- the search block 110 acquires pre-hazard external world information by reading pre-hazard external world information from the storage medium whose position information substantially matches the external world information acquired in S151. Note that the pre-hazard external world information may have been acquired by another autonomous driving device 1.
- the transmission block 120 outputs observation information corresponding to the external world information before and after the hazard to the remote center 2. More specifically, the transmission block 120 outputs, as observation information, difference information between the external world information acquired in the area search and the external world information before the hazard. The observation information may also include an analysis result for the difference. The output observation information is transmitted to the remote center 2 via the communication system 20. After the processing of S153, this flow proceeds to S170 in FIG. 5.
- the autonomous mobile device 1 searches for a disrupted device and transmits the search results to the remote center 2.
- the detailed processing in S160 will be explained with reference to the flowchart in FIG. 7.
- the search block 110 starts traveling to search for the disrupted device.
- the search block 110 acquires location information on the disrupted device immediately before the disruption from the remote center 2 or the like, and controls the traveling system 40 to head toward the disruption location where the disrupted device is estimated to be present.
- the disruption location is, for example, an area of a specified range that includes the location coordinates immediately before the disruption.
- the search block 110 determines whether the autonomous driving device 1 has arrived at the disruption location. The search block 110 continues searching for the disruption location until it determines that the autonomous driving device 1 has arrived at the disruption location. If it determines that the autonomous driving device 1 has arrived at the disruption location, the flow proceeds to S163.
- the search block 110 executes a diagnostic process regarding the state of the disrupted device at the disruption location.

- the search block 110 determines whether there is an instruction to end the search.
- the end instruction is sent to the autonomous mobile device 1 in response to the operation of a manager such as an operator at the remote center 2, for example. If there is no end instruction, the search block 110 executes the area search mode in S150. That is, the autonomous mobile device 1 in the area search mode expands the area search area within the facility until an end instruction is issued. Then, the autonomous mobile device 1 in the disconnected device search mode transitions to the area search mode if there is no end instruction after searching for a disconnected device. As a result, the proportion of devices executing the area search mode among the autonomous mobile devices 1 in the active state increases over time. When an end instruction is acquired, this flow ends and the search process is completed. After the search ends, the autonomous mobile device 1 may wait at the search end point, or may leave the travel area A in response to evacuation information from the remote center 2.

- the evacuation information generation method in which the server device 2b generates evacuation information for the driving area A of the autonomous driving device 1 by cooperation of these blocks 210 and 220 is executed according to the evacuation information generation flow shown in FIG. 8.
- This evacuation information generation flow is executed repeatedly while the dedicated computer is running. Note that each "S" in this evacuation information generation flow represents multiple steps executed by multiple commands included in the evacuation information generation program.
- the collection block 210 determines whether a hazard has occurred.
- the collection block 210 may determine the occurrence of a hazard when hazard occurrence information is acquired from at least one of the following sources: distribution from a public communication network such as the Internet, a report from a facility, and information provided by a fire department or the like.
- the collection block 210 waits for the flow to proceed until it determines that an event has occurred. If it determines that a hazard has occurred, the flow proceeds to S210.
- the output block 220 outputs the hazard information to the autonomous mobile device 1.
- the hazard information is transmitted to each autonomous mobile device 1 in the travel area A via the communication device 2a.
- the collection block 210 executes allocation of search modes to the autonomous mobile devices 1 in the travel area A. Specifically, the collection block 210 identifies active devices without fault notifications, i.e., autonomous mobile devices 1 that are capable of traveling, by communicating with the autonomous mobile devices 1. The collection block 210 then allocates the identified autonomous mobile devices 1 to devices that execute the area search mode and devices that execute the disrupted device search mode. For example, the collection block 210 may allocate the disrupted device search mode to the autonomous mobile device 1 closest to each disruption location, and allocate the other autonomous mobile devices 1 to the area search mode. The collection block 210 may assign multiple autonomous mobile devices 1 to one disruption location. The collection block 210 outputs the allocation result to each autonomous mobile device 1, causing each autonomous mobile device 1 to execute the search mode corresponding to it.
- active devices without fault notifications i.e., autonomous mobile devices 1 that are capable of traveling
- the collection block 210 then allocates the identified autonomous mobile devices 1 to devices that execute the area search mode and devices that execute the disrupted device search mode. For example, the collection
- step S230 the collection block 210 acquires observation information from an area search from each autonomous mobile device 1 that is active.
- step S240 the collection block 210 acquires observation information from a search for a disrupted device from each autonomous mobile device 1 that is active. Note that the processing of steps S230 and S240 may be performed in parallel.
- the collection block 210 continues the acquisition process until sufficient location observation information has been collected to generate a hazard map, and then proceeds to step S250.
- the output block 220 generates a hazard map according to each piece of observation information.
- the hazard map is evacuation information in map format that indicates the hazard level for each location within the driving area A.
- the hazard level is the degree of danger to the user of the driving area A.
- the user is, for example, a person.
- the user may be the autonomous driving device 1.
- the output block 220 may estimate the hazard level for each type of user.
- the output block 220 estimates the hazard level of the corresponding location from each piece of observation information. For example, as shown in FIG. 11, the output block 220 estimates the hazard level for each location, which is a small section of the driving area A, according to the observation information for the corresponding position.
- the output block 220 sets multiple hazard levels according to information from the observation information.
- the output block 220 sets five hazard levels, from lowest to highest, which are zero, low, medium, high, and the highest level of danger.
- the magnitude of the hazard level is the same for both people and the autonomous driving device 1.
- the output block 220 determines whether there is damage to nearby walls, whether there are cave-ins in the floor, and whether there are obstacles on the floor for each location based on the observation information obtained by area search, and determines the hazard level based on the state of the location estimated from the results of the determination.
- the output block 220 determines that there is no wall damage, no floor collapse, and no obstacle, it presumes that there is no abnormality in that location. In this case, the output block 220 determines the hazard level to be zero. Also, if the output block 220 determines that there is an obstacle without any wall damage or floor collapse, it determines the hazard level for that location to be between low and high. The smaller the passable area is due to an obstacle, the higher the hazard level the output block 220 determines for that area and the obstacle position. The output block 220 may determine the hazard levels for the obstacle position and the passable area separately.
- the output block 220 determines that there is no damage to the walls, that there is a collapsed floor, and that there are no obstacles, it presumes that the floor is missing at that location. In this case, the output block 220 determines the hazard level to be between medium and high. The smaller the passable area is due to a collapsed floor, the higher the hazard level the output block 220 determines for that area and the collapsed part. The output block 220 may determine the hazard levels for the collapsed part and the passable area separately.
- the output block 220 determines that there is no damage to the walls, that there is a collapsed floor, and that there is an obstacle, it presumes that the floor at that location has been damaged by a fallen heavy object, and that the heavy object or its fragments are scattered on the floor. In this case, the output block 220 determines the hazard level to be high. Furthermore, if the output block 220 determines that there is damage to the walls, that there is no collapsed floor, and that there are no obstacles, it determines the hazard level at that location to be low.
- the output block 220 determines that there is damage to the wall, no collapse in the floor, and the presence of an obstacle, it presumes that an object installed on the wall at that location has fallen onto the floor. In this case, the output block 220 determines the hazard level to be low to medium. The smaller the passable area becomes due to the falling object, the higher the hazard level the output block 220 determines for that area and the position of the falling object. The output block 220 may determine the hazard levels for the position of the falling object and the passable area separately.
- the output block 220 determines that there is wall damage, a floor collapse, and no obstacles, it presumes that the structure of the wall or floor has changed due to the hazard. In this case, the output block 220 determines the hazard level to be high. Also, if the output block 220 determines that there is wall damage, a floor collapse, and/or an obstacle, it presumes that the shape of the wall or floor has not been maintained due to the hazard, or that the floor has been significantly deformed and environmental recognition is not being performed normally. In this case, the output block 220 determines the hazard level to be the highest.
- the output block 220 determines the status of the disrupted device from the observation information obtained by searching for the disrupted device. For example, the output block 220 determines whether local communication is possible with the disrupted device, whether the disrupted device has been found, and whether the external appearance of the disrupted device is damaged. The output block 220 determines the hazard level at the disruption location from the status of the disrupted device estimated from the determination result.
- the output block 220 determines that local communication is possible, that it has been found, and that there is no external damage, it determines that only the disruption device's communication function with the center is damaged. In this case, the output block 220 determines the hazard level for people to be zero. In this case, the output block 220 also sets the hazard level for the autonomous driving device 1 to low. In addition, if the output block 220 determines that local communication is possible, that it has been found, and that there is external damage, it presumes that the disruption device's communication function with the center and its casing have been damaged by an external impact. In this case, the output block 220 determines the hazard level to be medium.
- the output block 220 determines that local communication is possible, but that the device has not been found and it is not possible to determine whether there is any external damage, it presumes that the disrupted device has been left behind in an area where other autonomous driving devices 1 cannot enter. In this case, the output block 220 determines the hazard level to be high.
- the output block 220 determines that local communication is not possible, that a detection has occurred, and that there is no external damage, it presumes that the communication function is not available due to an abnormality in the network card, the generation of jamming radio waves, etc. In this case, the output block 220 determines the hazard level for people to be low. Also, in this case, the output block 220 determines the hazard level for the autonomous mobile device 1 to be medium.
- the output block 220 determines that local communication is not possible, that the device has been found, and that there is external damage, it presumes that serious damage has occurred to the hardware of the disruption device due to an external impact. In this case, the output block 220 determines the hazard level to be high. Then, if the output block 220 determines that it is not possible to determine whether there is external damage because local communication is not possible and the device has not been found, it presumes that the status of the disruption device cannot be confirmed because it has been caught up in the collapse of a facility, for example. In this case, the output block 220 determines the hazard level to be the highest.
- the output block 220 By setting the hazard level for each location as described above, the output block 220 generates a hazard map M in which a hazard level is defined for each subdivision, as shown in FIG. 11. In FIG. 11, the darker the hatching of the dots, the higher the hazard level. Subdivisions with no hatching are locations where the hazard level is set to zero.
- the output block 220 In the next step S260, the output block 220 generates evacuation route data within the driving area A.
- the evacuation route data is evacuation information in a map format that represents the evacuation route Re within the driving area A.
- the output block 220 generates the evacuation route data based on the hazard map M generated in S250.
- the output block 220 searches for a route with the smallest hazard cost from a specified starting point to the exit of the travel area A, and sets the route as the evacuation route Re.
- the starting point of the evacuation route Re is, for example, the current location of an evacuee detected in the travel area A.
- the evacuation route Re may start at any position.
- the starting point of the hazard cost is a cost according to the hazard level in the hazard map M.
- the hazard cost is a parameter related to the sum of the hazard levels of each location passed through, which is quantified so that the higher the level, the larger the value. Note that in the example shown in FIG.
- the evacuation route Re with the lowest hazard level (zero) is shown, but it is also possible to pass through locations with a hazard level greater than zero as long as the hazard cost is minimized.
- the output block 220 may generate evacuation route data with a constraint that locations with a hazard level or higher than a specified hazard level are not passed through regardless of the hazard cost.
- the output block 220 outputs the hazard map M and evacuation route data.
- the output block 220 may output this evacuation information to a rescue organization such as a fire department.
- the output block 220 may output this evacuation information to the autonomous mobile device 1 in the travel area A.
- the output block 220 may output this evacuation information to personnel such as an operator at the remote center 2.
- the output block 220 outputs the evacuation route data in association with the hazard map M.
- the output block 220 associates the data so that the position of the evacuation route Re is presented on the hazard map M, as shown in FIG. 11.
- a hazard map M is output according to observation information by the autonomous driving device for a driving area A where the occurrence of a hazard is predicted. Therefore, the hazard map M for each location can reflect actual observation information for that location. Therefore, effective evacuation information can be generated.
- route evacuation data corresponding to observation information by the autonomous driving device regarding driving area A where the occurrence of a hazard is predicted is output. Therefore, actual observation information can be reflected in the evacuation route data within driving area A. Therefore, effective evacuation information can be generated.
- evacuation route data is output in association with the hazard map M. Therefore, highly convenient evacuation information that allows users to grasp both the hazard level and evacuation route data can be provided.
- acquiring observation information includes acquiring observation information obtained by searching the travel area A using an active device that can communicate with the outside, among the multiple autonomous driving devices 1. Therefore, evacuation information can be generated using an active device that can communicate with the outside.
- acquiring observation information includes acquiring observation information by searching for the facilities that make up the travel area A using an active device. This makes it possible to generate evacuation information according to damage to the travel area A caused by a hazard.
- acquiring the observation information includes acquiring the observation information obtained by searching for a disconnected device that has lost communication with the outside world within the travel area A among the multiple autonomous driving devices 1 using an active device. Then, outputting the evacuation information includes outputting a hazard map M that indicates the hazard level of the location where the disconnected device is estimated to be present as a hazard level according to the state of the searched disconnected device. Therefore, by utilizing the active device, evacuation information according to the state of the disconnected device can be generated.
- outputting evacuation information includes outputting a hazard map M that indicates a hazard level according to the state of mutual communication between the active device and the disconnected device. Therefore, evacuation information can be generated that utilizes the state of mutual communication between the active device and the disconnected device.
- outputting evacuation information includes outputting a hazard map M that indicates a hazard level according to the observation state of the disruption device by the active device.
- evacuation information according to the observation state of the disruption device can be generated by utilizing the active device.
- some of the functions executed by the server device 2b may be executed by another control device, such as the information processing device 100 of the autonomous driving device 1. Also, in a modified example, some of the functions executed by the information processing device 100 may be executed outside the autonomous driving device 1, such as the remote center 2.
