Abstract

A reporting device that is connected to at least one vehicle, which is controlled based on a result of recognition by an outside recognizer, via a network provides the vehicle with information on a possibility of a failure in outside recognition on the basis of a condition under which a failure in outside recognition has occurred previously. Preliminarily, if a failure such as non-detection or erroneous detection occurs due to an outside recognizer of a connected car, the abnormality is stored while being linked with an external traveling environment such as the position of the vehicle or a weather.

Claims

1. A reporting device comprising:

a vehicle outside recognition result acquirer connected to each of a plurality of vehicles via a network;

an outside recognition failure detector coupled to the vehicle outside recognition result acquirer;

an outside recognition failure cause analyzer coupled to said outside recognition failure detector and which is controlled based on information of a result of recognition determined by an outside recognizer of one of said plurality of vehicles, said information of the result of recognition being received by the vehicle outside recognition result acquirer via the network; and

an outside recognition failure storage device coupled to said outside recognition failure cause analyzer and which stores an external environment for which an outside recognition failure has occurred previously for each of said plurality of vehicles,

wherein the outside recognition failure cause analyzer is configured to determine information on a possibility of a failure in outside recognition for the plurality of vehicles on the basis of said stored external environment for which the failure in outside recognition has occurred previously.

2. The reporting device according to claim 1,

wherein a failure in outside recognition is detected based on a behavior of another of said plurality of vehicles which is a preceding vehicle with respect to said one vehicle of the plurality of vehicles, and which is traveling on a same lane with respect to said one vehicle, and a change in a relative distance of said one vehicle from said preceding vehicle.

3. The reporting device according to claim 1,

wherein a failure in outside recognition is detected based on an outcome of a brake command, which is issued from an autonomous drive or a drive assist function included in each of the plurality of vehicles, and the contents of a brake maneuver performed by a driver.

4. The reporting device according to claim 1,

wherein a failure in outside recognition is detected based on previous successes and failures in outside recognition which are preliminarily classified and learned.

5. The reporting device according to claim 1, further comprising:

an external environment acquirer configured to acquire said external environment of the plurality of vehicles,

wherein said external environment acquirer is configured to store a failure in outside recognition in association with said external environment using the outside recognition failure storage device.

6. The reporting device according to claim 5,

wherein when a degree of consistency of a current external environment of the plurality of vehicles with an external environment associated with a failure in outside recognition stored in the outside recognition failure storage is high, a possibility of a failure in outside recognition of the plurality of vehicles is determined to be high.

7. The reporting device according to claim 2, comprising:

an external environment acquirer configured to acquire said external environment of the plurality of vehicles,

wherein said external environment acquirer is configured to store a failure in outside recognition in association with said external environment using the outside recognition failure storage device.

8. The reporting device according to claim 7,

wherein when a degree of consistency of a current external environment of the plurality of vehicles with an external environment associated with a failure in outside recognition stored in the outside recognition failure storage is high, a possibility of a failure in outside recognition of the plurality of vehicles is determined to be high.

9. The reporting device according to claim 3, comprising:

an external environment acquirer configured to acquire said external environment of the plurality of vehicles,

wherein said external environment acquirer is configured to store a failure in outside recognition in association with said external environment using the outside recognition failure storage device.

10. The reporting device according to claim 9,

wherein when a degree of consistency of a current external environment of the plurality of vehicles with an external environment associated with a failure in outside recognition stored in the outside recognition failure storage is high, a possibility of a failure in outside recognition of the plurality of vehicles is determined to be high.

11. The reporting device according to claim 4, comprising:

an external environment acquirer configured to acquire said external environment of the plurality of vehicles,

wherein said external environment acquirer is configured to store a failure in outside recognition in association with said external environment using the outside recognition failure storage device.

12. The reporting device according to claim 11,

wherein when a degree of consistency of a current external environment of the plurality of vehicles with an external environment associated with a failure in outside recognition stored in the outside recognition failure storage is high, a possibility of a failure in outside recognition of the plurality of vehicles is determined to be high.
