Vehicle diagnosis method and information presentation method
A computer of a vehicle diagnosis system acquires a sound produced in a traveling vehicle. The computer of the vehicle diagnosis system diagnoses a status of the vehicle based on the sound acquired. The computer of the vehicle diagnosis system causes a diagnosis result indicating the status of the vehicle to be output from an apparatus mounted on the vehicle.
1. A vehicle diagnosis method executed in a device that communicates with a vehicle-mounted apparatus and includes a database that records an abnormal sound in association with a vehicle status, the method comprising:
acquiring a sound transmitted from the vehicle-mounted apparatus and produced in a traveling vehicle;
diagnosing a status of the vehicle based on the sound acquired; and
transmitting diagnosis result data on the status of the vehicle to the vehicle-mounted apparatus to cause the vehicle-mounted apparatus to display a diagnosis result screen, wherein
the diagnosis result data includes abnormal sound site information on a site where the abnormal sound is produced, a method of handling including information related to an action that a passenger of the vehicle should take, and evidence information on the abnormal sound site information and the method of handling, and
the diagnosis result screen includes (i) an image indicating a position of an abnormal sound site based on the abnormal sound site information, (ii) at least one of sound waveform or frequency characteristics of the sound used in the diagnosis based on the evidence information, and (iii) the method of handling.
2. The vehicle diagnosis method according to claim 1 , further comprising:
acquiring traveling data for the vehicle; and
diagnosing the status of the vehicle based on the sound acquired and the traveling data acquired.
3. The vehicle diagnosis method according to claim 1 , wherein
an abnormal sound is detected by comparing current traveling sound acquired and traveling sound in normal times, and
the status of the vehicle is diagnosed when the abnormal sound is detected.
4. The vehicle diagnosis method according to claim 1 , wherein
the diagnosis result screen further includes a button configured to receive an instruction from the passenger to request a use of an external service based on the method of handling, and
when the button is pressed, data necessary to use the external service is transmitted to the external service.
5. The vehicle diagnosis method according to claim 1 , wherein
the vehicle-mounted apparatus includes at least one of a car navigation system or an In-Vehicle Infotainment system, and
the sound transmitted from the vehicle-mounted apparatus and produced in the traveling vehicle is collected by a microphone mounted on the vehicle.
6. The vehicle diagnosis method according to claim 1 , wherein
the diagnosis result screen further includes a text indicating the position of the abnormal sound site based on the abnormal sound site information.
7. The vehicle diagnosis method according to claim 1 , wherein
the sound produced in the traveling vehicle is collected when the passenger of the vehicle enters a predetermined user operation.
8. The vehicle diagnosis method according to claim 1 , wherein
the acquiring acquires a first sound that is the sound transmitted from the vehicle-mounted apparatus and produced in the vehicle, and
the vehicle diagnosis method further includes detecting an abnormal sound by comparing the first sound and traveling sound in normal times.
9. The vehicle diagnosis method according to claim 8 , wherein
the acquiring acquires a second sound that is the sound transmitted from the vehicle-mounted apparatus and produced in the vehicle after the abnormal sound is detected, and
the diagnosing diagnoses the status of the vehicle based on the second sound.
10. An information presentation method executed in a vehicle-mounted apparatus that communicates with a device including a database that records an abnormal sound in association with a vehicle status, the method comprising:
transmitting a sound produced in a traveling vehicle to the device;
acknowledging diagnosis result data transmitted from the device and indicating a status of the vehicle based on the sound;
generating a diagnostic result screen based on the diagnosis result data; and
outputting the diagnosis result screen to a display to be displayed on the display, wherein
the diagnosis result data includes abnormal sound site information on a site where the abnormal sound is produced, a method of handling including information related to an action that a passenger of the vehicle should take, and evidence information on the abnormal sound site information and the method of handling, and
the diagnosis result screen includes (i) an image indicating a position of an abnormal sound site based on the abnormal sound site information, (ii) at least one of sound waveform or frequency characteristics of the sound used in the diagnosis based on the evidence information, and (iii) the method of handling.
11. The information presentation method according to claim 10 , wherein
data for the sound used in a diagnosis by the device is saved.
12. The information presentation method according to claim 10 , wherein
the method of handling includes content that prompts one to use a predetermined service, and
the information presentation method further includes communicating with an apparatus related to the service in accordance with a user operation of the passenger of the vehicle.
13. The information presentation method according to claim 12 , wherein
the diagnosis result data includes content that prompts a passenger to make a reservation for a check of vehicle by using an operator service.
14. The information presentation method according to claim 10 , wherein
the diagnosis result screen further includes a button configured to receive an instruction from the passenger to request a use of an external service based on the method of handling, and
when the button is pressed, data necessary to use the external service is transmitted to the external service.
15. The information presentation method according to claim 10 , wherein
the vehicle-mounted apparatus includes at least one of a car navigation system or an In-Vehicle Infotainment system, and
the sound produced in the traveling vehicle is collected by a microphone mounted on the vehicle and is transmitted to the device.
16. The information presentation method according to claim 10 , wherein
the diagnosis result screen further includes a text indicating the position of the abnormal sound site based on the abnormal sound site information.
17. The information presentation method according to claim 10 , wherein
data for the sound used in a diagnosis by the device, traveling data for the vehicle, and the diagnosis result data are saved.
18. The information presentation method according to claim 10 , wherein
the transmitting transmits a first sound that is the sound produced in the vehicle, and
the method further includes acquiring an abnormal sound detection result transmitted from the device based on the first sound.
19. The information presentation method according to claim 18 , wherein
the transmitting transmits a second sound that is the sound produced in the vehicle after the abnormal sound detection result indicates that the abnormal sound is produced, and
the acknowledging acknowledges the diagnosis result transmitted from the device and indicating the status of the vehicle based on the second sound.
