Abstract
A software management system includes a server device, a maintenance device communicating with the server device, an electronic control device provided in a vehicle, a communication device provided in the vehicle, and a gateway device provided in the vehicle and communicating with the maintenance device, the electronic control device, and the communication device. The server device manages version information of software of the electronic control device in association with a control device ID of the electronic control device and the gateway device stores a correspondence between the control device ID and a communication ID of the electronic control device, and further the maintenance device instructs the gateway device to set the correspondence between the control device ID and the communication ID. The gateway device acquires the version information from the electronic control device and notifies the server device of configuration information associating the version information and the control device ID.
