TECHNICAL FIELD

The present invention relates to monitoring of autonomous driving vehicles.

BACKGROUND ART

In recent years, an ADAS (Advanced Driver Assistance System) represented by automatic braking, Adaptive Cruise Control, and the like has been on the market. Further, research and development of the autonomous driving and traveling technology has been in progress, and a plurality of automobile manufactures have been running demonstration trials on public roads. Research and development of the automatic parking technology has been actively conducted as a part of the autonomous driving and traveling technology, and a plurality of automobile manufacturers have been marketing vehicles with an automatic parking function incorporated therein.

In most of automatic parking functions, when a driver selects a parking position on a touch panel, the vehicle autonomously travels to be parked at the selected parking position.

A valet parking service is provided at hotels and restaurants in some cases. In valet parking, when a key of a vehicle is handed to a manager at a hotel entrance or a restaurant entrance, the manager parks the vehicle on behalf of the driver. When the valet parking is to be realized by an automatic parking function, the vehicle needs to travel autonomously in an unmanned state. Due to the advancement of autonomous driving technology, unmanned automatic parking can be conducted in normal cases. However, when the parking lot is congested, in order to secure safety, there is a case where each of autonomous driving vehicles stops its traveling. Further, when both autonomous driving vehicles and manual driving vehicles are present in a mixed manner in a parking lot, automatic parking becomes more difficult as compared to a case where there are only autonomous driving vehicles.

As described above, when a parking lot is congested and when autonomous driving vehicles and manual driving vehicles are present in a mixed manner in a parking lot, automatic parking becomes difficult. When such circumstances are assumed, it is necessary that the automatic parking function of an autonomous driving vehicle is assisted by human so as not to cause any accident.

In this regard, Patent Literature 1 discloses a parking assistance system. In Patent Literature 1, images captured by a vehicle-mounted camera of a vehicle to be parked are transmitted to a manager of a parking lot. The manager monitors the images captured by the vehicle-mounted camera, drives the vehicle on behalf of its driver with simulated steering, and parks the vehicle.

Due to the technology of Patent Literature 1, the manager of the parking lot can drive the vehicle on behalf of its driver even when the manager is at a location away from the parking lot.

Patent Literature 2 discloses a technology of stopping an autonomous driving vehicle using a smartphone. In Patent Literature 2, a driving-status notification image indicating a position of an autonomous driving vehicle and persons and obstacles around the autonomous driving vehicle is presented on a smartphone of a driver. When the driver judges that it is necessary to stop the autonomous driving vehicle, the driver operates a stop button to stop the autonomous driving vehicle.

Due to the technology of Patent Literature 2, it is possible that the driver confirms the driving status of the autonomous driving vehicle that is conducting automatic parking and operates a stop button when there is a danger, thereby stopping the autonomous driving vehicle.

SUMMARY OF INVENTION

Technical Problem

In the technologies of Patent Literatures 1 and 2, one manager needs to perform driving assistance for one autonomous driving vehicle. Therefore, in the technology of Patent Literature 1 and the technology of Patent Literature 2, there is a problem that in a facility such as a parking lot, when the number of autonomous driving vehicles becomes large, assistance provided by the manager becomes insufficient, and the possibility of occurrence of an accident caused by autonomous driving vehicles that are conducting automatic parking in the facility such as a parking lot becomes high.

The present invention has a main object to solve the problem described above. More specifically, the main object of the present invention is to obtain a configuration that effectively prevents accidents caused by autonomous driving vehicles in a facility.

Solution to Problem

An information processing device according to the present invention includes:

an image-data acquisition unit to acquire a plurality of pieces of image data in which different areas in a facility in which an autonomous driving vehicle conducts autonomous traveling are shown;

a priority setting unit to analyze a status shown in each of the plurality of pieces of image data and to set a priority to each image data; and

a display control unit to decide a display mode at a time of displaying the plurality of pieces of image data according to the priority set by the priority setting unit.

Advantageous Effects of Invention

According to the present invention, one manager can perform driving assistance for a plurality of autonomous driving vehicles and accidents caused by autonomous driving vehicles in a facility can be effectively prevented.
