Abstract

A software distribution system includes an acquiring unit configured to acquire, from vehicles, error information about an in-vehicle software component having an error; a holding unit configured to hold acquired error information in association with vehicle information of the vehicle from which the error information is acquired; an identifying unit configured to identify an information element common to a plurality of pieces of vehicle information associated with the same error information; and a distribution unit configured to distribute a correction file for correcting the error in the in-vehicle software component to a vehicle group having the identified information element.

First claim

What is claimed is:

1 . A software distribution system comprising:
an acquiring unit configured to acquire, from vehicles, error information about an in-vehicle software component having an error; a holding unit configured to hold acquired error information in association with vehicle information of the vehicle from which the error information is acquired; an identifying unit configured to identify an information element common to a plurality of pieces of vehicle information associated with the same error information; and a distribution unit configured to distribute a correction file for correcting the error in the in-vehicle software component to a vehicle group having the identified information element.

2 . The software distribution system according to claim 1 , further comprising a group setting unit configured to set the vehicle group having the information element identified by the identifying unit to a destination to which the correction file for correcting the error in the in-vehicle software component is distributed.

3 . The software distribution system according to claim 1 , wherein:
each piece of the vehicle information contains travel environment information of the associated vehicle when there occurs the error in the in-vehicle software component as the information element; and the identifying unit is configured to identify the information element common to the same error information based on pieces of travel environment information of a plurality of the vehicles that have sent the error information.

4 . A software distribution method comprising:
a step of acquiring, from vehicles, error information about an in-vehicle software component having an error; a step of holding acquired error information in association with vehicle information of the vehicle from which the error information is acquired; a step of identifying an information element common to a plurality of pieces of vehicle information associated with the same error information; and a step of distributing a correction file for correcting the error in the in-vehicle software component to a vehicle group having the identified information element.
