Abstract

A driverless transportation system includes an autonomous driving vehicle and a management server. A check code includes: a vehicle code unique to the autonomous driving vehicle; and a passcode whose value changes each time it is generated. In deactivation processing, the autonomous driving vehicle newly generates the passcode, stores the check code including the newly-generated passcode, as a first check code, and transmits the first check code to the management server. The management server stores the first check code as a stored check code. In order to activate the autonomous driving vehicle, the management server transmits an activation instruction and the stored check code to the autonomous driving vehicle. In response to that, the autonomous driving vehicle reads the check code from its memory device, as a second check code, and determines whether or not the second check code and the stored check code match.

First claim

What is claimed is:

1. A driverless transportation system that provides a driverless transportation service, comprising:
an autonomous driving vehicle comprising a memory device; and
a remote management server managing the autonomous driving vehicle,
wherein a check code includes:
a vehicle code unique to the autonomous driving vehicle; and
a passcode whose value changes each time it is generated,
wherein in deactivation processing to enter a standby mode, the autonomous driving vehicle newly generates the passcode, stores the check code including the newly-generated passcode, as a first check code, in the memory device, and further transmits the first check code to the remote management server, and
the remote management server stores the first check code as a stored check code,
wherein at a time of activating the autonomous driving vehicle, the remote management server transmits an activation instruction and the stored check code to the autonomous driving vehicle,
the autonomous driving vehicle, in response to the activation instruction, reads the check code stored in the memory device, as a second check code, and determines whether or not the second check code and the stored check code match, and
the autonomous driving vehicle performs first abnormality handling processing when the second check code and the stored check code do not match.

2. The driverless transportation system according to claim 1 ,
wherein check information includes at least one of position-orientation information indicating a position and an orientation of the autonomous driving vehicle, driving history information indicating a driving history of the autonomous driving vehicle, and surroundings image information indicating an image around the autonomous driving vehicle,
wherein in the deactivation processing, the autonomous driving vehicle newly acquires the check information as first check information, and transmits the first check information to the remote management server, and
the remote management server stores the first check information as stored check information,
wherein in response to the activation instruction, the autonomous driving vehicle newly acquires the check information as second check information, and transmits the second check information to the remote management server,
the remote management server compares the second check information with the stored check information to determine whether or not the autonomous driving vehicle is driven without permission, and
the remote management server performs second abnormality handling processing when determining that the autonomous driving vehicle is driven without permission.

3. The driverless transportation system according to claim 2 ,
wherein the check information further includes vehicle image information indicating at least one of images of a room and appearance of the autonomous driving vehicle,
the remote management server compares the vehicle image information included in the second check information with the vehicle image information included in the stored check information to determine whether or not a change occurs in the room or the appearance of the autonomous driving vehicle, and
the remote management server performs third abnormality handling processing when determining that the change occurs.

4. The driverless transportation system according to claim 1 ,
wherein check information includes vehicle image information indicating at least one of images of a room and appearance of the autonomous driving vehicle,
wherein in the deactivation processing, the autonomous driving vehicle newly acquires the check information as a first check information, and transmits the first check information to the remote management server, and
the remote management server stores the first check information as a stored check information,
wherein in response to the activation instruction, the autonomous driving vehicle newly acquires the check information as a second check information, and transmits the second check information to the remote management server,
the remote management server compares the second check information with the stored check information to determine whether or not a change occurs in the room or the appearance of the autonomous driving vehicle, and
the remote management server performs third abnormality handling processing when determining that the change occurs.

5. The driverless transportation system according to claim 1 , wherein the deactivation processing comprises turning off an ignition of the autonomous driving vehicle.
