摘要
A method used in an on-board network system, having electronic controllers that exchange messages and a fraud detecting electronic controller. The method includes determining whether a message transmitted conforms to fraud detection rules, and querying an external device whether there is delivery data for updating the fraud detection rules. When there is the delivery data for updating the fraud detection rules, receiving from an external device the delivery data, including updated fraud detection rules and network type information indicating a network type that the updated fraud detection rules are to be applied. The method also includes determining whether a vehicle in which the on-board network system is installed is running, and whether the network type information indicates a drive network that is connected to an electronic controller related to travel of the vehicle. When the network type information does not indicate the drive network, updating the fraud detection rules.
