To provide a vehicle maintenance system capable of conducting maintenance on a plurality of vehicles while securing communication security.SOLUTION: A vehicle maintenance system 10 comprises a plurality of maintenance tool appliances 1 that are connected to a plurality of vehicles-of-interest 7 and a transmitter 9 that sends a plurality of divisional data obtained by dividing for-maintenance data to particular maintenance tool appliances of a plurality of maintenance tool appliances equal in the number to the plurality of divisional data through a communication network 92. Each of the plurality of maintenance tool appliances has a first communicating section that receives destined-to-own-device divisional data the transmitter has sent, a second communicating section that sends the destined-to-own-device divisional data the first communicating section has received to all the other maintenance tool appliances and receives destined-to-another-device divisional data all the other particular maintenance tool appliances hold, and a restoring section that restores for-maintenance data from the destined-to-own-device divisional data the first communicating section has received and destined-to-all-the-other-devices divisional data the second communicating section has received.SELECTED DRAWING: Figure 1

    【課題】通信セキュリティを確保しつつ複数の車両に対して保守を行うことを可能とする車両用保守システムを提供する。【解決手段】車両用保守システム10は、複数の対象車両7に接続される複数の保守ツール機器1と、保守用データの分割により得られる複数の分割データを、複数の保守ツール機器のうちの複数の分割データと同数の特定の保守ツール機器に、通信ネットワーク92を介して送信する送信機器9と、を備える。複数の保守ツール機器の各々は、送信機器が送信した自機宛ての分割データを受信する第1通信部と、第1通信部が受信した自機宛ての分割データを他の全ての保守ツール機器に送信すると共に、他の全ての特定の保守ツール機器が保有する他機宛ての分割データを受信する第2通信部と、第1通信部が受信した自機宛ての分割データおよび第2通信部が受信した全ての他機宛ての分割データから保守用データを復元する復元部と、を有する。【選択図】図1
