cause an electronic control unit of each of the at least one first autonomous driving vehicle to control traveling of the at least one first autonomous driving vehicle based on the travel instruction;

set a priority representing a degree of priority in which an instruction terminal including a display device and an input device is notified of the travel instruction in an order determined according to content of the abnormality, for each of the at least one first autonomous driving vehicle;

notify any one of at least one instruction terminal of the determined travel instruction to the first autonomous driving vehicle, among the at least one first autonomous driving vehicle, in the order of priority;

receive a result of checking the determined travel instruction from the at least one instruction terminal;

calculate the priority by multiplying a risk degree by a value obtained by dividing a difference between a maximum value of a settable allowable time and an allowable time by the maximum value,

wherein the risk degree represents a degree of risk that is determined according to the content of the abnormality of the first autonomous driving vehicle, and wherein the allowable time is an allowable time for checking the travel instruction to the first autonomous driving vehicle; and

increase the priority as the risk degree increases or the allowable time decreases.

2. The vehicle control device according to claim 1 , wherein:

the communication interface is configured to receive state information indicating a state of the first autonomous driving vehicle at a time when the abnormality occurs, for each of the at least one first autonomous driving vehicle; and

the processor is configured to set the allowable time according to the state of the first autonomous driving vehicle indicated in the state information of each of the at least one first autonomous driving vehicle.

3. The vehicle control device according to claim 1 , wherein the processor is configured to, according to the content of the abnormality of each of the at least one first autonomous driving vehicle, determine whether to notify the travel instruction to any one of the at least one instruction terminal after or before transmitting the travel instruction to each of the at least one first autonomous driving vehicle.

4. The vehicle control device according to claim 3 , wherein the processor is configured to, when the content of the abnormality is a misbehavior of an occupant, notify the determined travel instruction to any one of the at least one instruction terminal, receive, before transmitting the determined travel instruction to the first autonomous driving vehicle, the result of checking the determined travel instruction from the at least one instruction terminal, and transmit, to the first autonomous driving vehicle, a travel instruction determined based on the checking result.

5. A vehicle control method, comprising:

determining, when an abnormality occurs in or around at least one first autonomous driving vehicle among a plurality of autonomous driving vehicles that is configured to perform autonomous traveling, a travel instruction for controlling traveling of each of the at least one first autonomous driving vehicle;

transmitting the travel instruction to each of the at least one first autonomous driving vehicle via a communication interface configured to communicate with the plurality of autonomous driving vehicles;

causing an electronic control unit of each of the at least one first autonomous driving vehicle to control traveling of the at least one first autonomous driving vehicle based on the travel instruction;

setting a priority representing a degree of priority in which an instruction terminal including a display device and an input device is notified of the travel instruction in an order determined according to content of the abnormality, for each of the at least one first autonomous driving vehicle;

notifying any one of at least one instruction terminal of the determined travel instruction to the first autonomous driving vehicle, among the at least one first autonomous driving vehicle, in the order of priority;

receiving a result of checking the determined travel instruction from the at least one instruction terminal,

calculating the priority by multiplying a risk degree by a value obtained by dividing a difference between a maximum value of a settable allowable time and an allowable time by the maximum value,

wherein the risk degree represents a degree of risk that is determined according to the content of the abnormality of the first autonomous driving vehicle, and wherein the allowable time is an allowable time for checking the travel instruction to the first autonomous driving vehicle; and

increasing the priority as the risk degree increases or the allowable time decreases.

6. A vehicle control system comprising:

at least one first autonomous driving vehicle among a plurality of autonomous driving vehicles that is configured to perform autonomous traveling; and

a vehicle control device configured to communicate with the plurality of autonomous driving vehicles via a communication network, wherein the vehicle control device includes a processor, and the processor is configured to:

when an abnormality occurs in or around the at least one first autonomous driving vehicle among the plurality of autonomous driving vehicles, determine a travel instruction for controlling traveling of each of the at least one first autonomous driving vehicle;

transmit the travel instruction to each of the at least one first autonomous driving vehicle via a communication interface;

cause an electronic control unit of each of the at least one first autonomous driving vehicle to control traveling of the at least one first autonomous driving vehicle based on the travel instruction;

set a priority representing a degree of priority in which an instruction terminal including a display device and an input device is notified of the travel instruction in an order determined according to content of the abnormality, for each of the at least one first autonomous driving vehicle;

notify any one of at least one instruction terminal of the determined travel instruction to the first autonomous driving vehicle, among the at least one first autonomous driving vehicle, in the order of priority;

receive a result of checking the determined travel instruction from the at least one instruction terminal;

calculate the priority by multiplying a risk degree by a value obtained by dividing a difference between a maximum value of a settable allowable time and an allowable time by the maximum value,

wherein the risk degree represents a degree of risk that is determined according to the content of the abnormality of the first autonomous driving vehicle, and wherein the allowable time is an allowable time for checking the travel instruction to the first autonomous driving vehicle; and

increase the priority as the risk degree increases or the allowable time decreases.
