Abstract

A vehicle management apparatus may include a collection unit configured to collect data indicating a state of a vehicle based on a detection result of a sensor configured to detect the state of the vehicle from a plurality of vehicles. The vehicle management apparatus may include a classification unit configured to classify the plurality of vehicles into a plurality of group according to a predetermined algorithm based on the data of each of the plurality of vehicles. The vehicle management apparatus may include an identification unit configured to identify, when a faulty vehicle in which a failure has occurred is present among the plurality of vehicles, another vehicle belonging to a group to which the faulty vehicle belongs from among a plurality of groups as a failure symptom vehicle having a symptom of occurrence of a failure.

First claim

What is claimed is:

1 . A vehicle management apparatus comprising:
a collection unit configured to collect data indicating a state of a vehicle detected by a sensor from a plurality of vehicles; a classification unit configured to classify the plurality of vehicles into a plurality of clusters according to a predetermined algorithm based on the data of each of the plurality of vehicles; and an identification unit configured to identify, when a faulty vehicle in which a failure has occurred is present among the plurality of vehicles, another vehicle belonging to a cluster to which the faulty vehicle belongs as a failure symptom vehicle having a symptom of occurrence of a failure.

2 . The vehicle management apparatus according to claim 1 , further comprising:
a notification unit configured to notify a notification destination associated with the failure symptom vehicle that a symptom of occurrence of a failure is present.

3 . The vehicle management apparatus according to claim 1 , wherein
the data indicating the state of the vehicle indicates at least one of a torque or a rotation speed of an engine or a motor generator, a temperature of engine oil, a hydraulic pressure of the engine oil, a temperature of hydraulic oil of an automatic transmission, an accelerator opening, a vibration of the vehicle, and a speed of the vehicle.

4 . The vehicle management apparatus according to claim 2 , wherein
the data indicating the state of the vehicle indicates at least one of a torque or a rotation speed of an engine or a motor generator, a temperature of engine oil, a hydraulic pressure of the engine oil, a temperature of hydraulic oil of an automatic transmission, an accelerator opening, a vibration of the vehicle, and a speed of the vehicle.

5 . The vehicle management apparatus according to claim 1 , wherein
the collection unit is configured to collect data related to an environment where the vehicle is present from the plurality of vehicles, and the classification unit is configured to classify the plurality of vehicles into the plurality of clusters based on the data related to the environment where the vehicle is present.

6 . The vehicle management apparatus according to claim 2 , wherein
the collection unit is configured to collect data related to an environment where the vehicle is present from the plurality of vehicles, and the classification unit is configured to classify the plurality of vehicles into the plurality of clusters based on the data related to the environment where the vehicle is present.

7 . The vehicle management apparatus according to claim 3 , wherein
the collection unit is configured to collect data related to an environment where the vehicle is present from the plurality of vehicles, and the classification unit is configured to classify the plurality of vehicles into the plurality of clusters based on the data related to the environment where the vehicle is present.

8 . The vehicle management apparatus according to claim 5 , wherein
the data related to the environment where the vehicle is present indicates at least one of an outside air temperature in a surrounding of the vehicle and an area where the vehicle is present.

9 . A vehicle management method comprising:
collecting data indicating a state of a vehicle detected by a sensor from a plurality of vehicles; classifying the plurality of vehicles into a plurality of clusters according to a predetermined algorithm based on the data of each of the plurality of vehicles; and identifying, when a faulty vehicle in which a failure has occurred is present among the plurality of vehicles, another vehicle belonging to a cluster to which the faulty vehicle belongs from among the plurality of clusters as a failure symptom vehicle having a symptom of occurrence of a failure.

10 . A computer readable recording medium having recorded thereon a program for causing a computer to execute:
collecting data indicating a state of a vehicle detected by a sensor from a plurality of vehicles; classifying the plurality of vehicles into a plurality of clusters according to a predetermined algorithm based on the data of each of the plurality of vehicles; and identifying, when a faulty vehicle in which a failure has occurred is present among the plurality of vehicles, another vehicle belonging to a cluster to which the faulty vehicle belongs as a failure symptom vehicle having a symptom of occurrence of a failure.
