Abstract

Warning guidance systems, methods, and programs communicate with a vehicle navigation system to provide guidance on a warning event that may occur on the vehicle. The systems, methods, and programs acquire warning event information indicating the warning event and an event vehicle on which the warning event has occurred. The systems methods and programs transmit the guidance to the vehicle traveling in a predetermined section in a case in which the warning event that has occurred a plurality of times in the predetermined section has occurred on a plurality of event vehicles, but do not transmit the guidance at another vehicle traveling in the predetermined section in a case in which the warning event that has occurred a plurality of times in the predetermined section has occurred on a single event vehicle for all of the plurality of times.

Claims

1. A warning guidance system for communicating with a vehicle navigation system to provide guidance on a warning event that may occur on the vehicle, the warning guidance system comprising:

a memory storing warning event information of a plurality of event vehicles; and

a processor operatively coupled to the memory, the processor being programmed to;

receive a guidance acquisition request requesting guidance information;

acquire warning event information indicating the warning event and an event vehicle on which the warning event occurred, and store the warning event information in the memory;

determine whether the warning event occurred a plurality of times in a predetermined location on the plurality of event vehicles;

responsive to determining that the warning event occurred the plurality of times in the predetermined location on the plurality of event vehicles, transmit the guidance information to each vehicle, from which the guidance request is received, traveling in the predetermined location; and

responsive to determining that the warning event occurred the plurality of times in the predetermined location on only the event vehicle of the plurality of event vehicles, transmit the guidance information only to the event vehicle upon receiving the guidance acquisition request from the event vehicle, wherein the transmitted guidance information is configured to cause the vehicle navigation system of each vehicle to output guidance based on the guidance information.

2. The warning guidance system according to claim 1, wherein the processor is programmed to:

transmit the guidance information to the event vehicle traveling in the predetermined location in a case in which the warning event that has occurred the plurality of times in the predetermined location has occurred on the event vehicle for all of the plurality of times.

3. The warning guidance system according to claim 1, wherein the processor is programmed to:

not transmit the guidance information to any other vehicle traveling in the predetermined location in a case in which;

the warning event that has occurred the plurality of times in the predetermined location has occurred on the event vehicle for all of the plurality of times; and

the predetermined location is within a predetermined distance from a home or a work location of a driver of the event vehicle.

4. The warning guidance system according to claim 1, wherein the processor is programmed to:

not transmit the guidance information to any other vehicle traveling in the predetermined location in a case in which;

the warning event that has occurred the plurality of times in the predetermined location has occurred on the event vehicle for all of the plurality of times; and

the predetermined location is on a route traveled by the event vehicle a predetermined number of times or more in a past.

5. The warning guidance system according to claim 1, wherein:

the warning event is an event in which a state value indicating a state of the event vehicle or a state of an environment of the event vehicle becomes greater than or equal to a threshold value or less than or equal to the threshold value.

6. A warning guidance method for communicating with a vehicle navigation system to provide guidance on a warning event that may occur on the vehicle, the warning guidance method comprising:

receiving, by a processor, a guidance acquisition request requesting guidance information;

acquiring warning event information indicating the warning event and an event vehicle on which the warning event occurred, and storing the warning event information in a memory;

determining whether the warning event occurred a plurality of times in a predetermined location on the plurality of event vehicles;

responsive to determining that the warning event occurred the plurality of times in the predetermined location on the plurality of event vehicles, transmitting the guidance information to each vehicle, from which the guidance request is received, traveling in the predetermined location; and

responsive to determining that the warning event occurred the plurality of times in the predetermined location on only the event vehicle of the plurality of event vehicles, transmitting guidance information only to the event vehicle upon receiving the guidance acquisition request from the event vehicle, wherein the transmitted guidance information is configured to cause the vehicle navigation system of each vehicle to output guidance based on the guidance information.

7. A non-transitory computer-readable storage medium storing a computer-executable warning guidance program for communicating with a vehicle navigation system to provide guidance on a warning event that may occur on the vehicle, the warning guidance program causing a computer to execute the following functions:

receiving a guidance acquisition request requesting guidance information;

acquiring warning event information indicating the warning event and an event vehicle on which the warning event occurred, and storing the warning event information in a memory;

determining whether the warning event occurred a plurality of times in a predetermined location on the plurality of event vehicles;

responsive to determining that the warning event occurred the plurality of times in the predetermined location on the plurality of event vehicles, transmitting the guidance information to each vehicle, from which the guidance request is received, traveling in the predetermined location; and

responsive to determining that the warning event occurred the plurality of times in the predetermined location on only the event vehicle of the plurality of event vehicles, transmitting guidance information only to the event vehicle upon receiving the guidance acquisition request from the event vehicle, wherein the transmitted guidance information is configured to cause the vehicle navigation system of each vehicle to output guidance based on the guidance information.
