A terminal device for use in a software rewriting system configured to rewrite a software package of a control device, including a storage unit configured to store one or more pieces of source code in a text format for generating one or more pieces of object code in a binary format executable by the control device. The terminal device retrieves a piece of difference source code which is a difference in a piece of source code corresponding to a current piece of object code stored in the storage unit, generates a latest piece of source code based on the piece of difference source code retrieved and the one or more pieces of source code stored in the storage unit, converts the latest piece of source code into a latest piece of object code, and transmits the latest piece of object code obtained from the conversion to the control device.

Terminal device and software rewriting program

A terminal device for use in a software rewriting system configured to rewrite a software package of a control device mounted on a movable object, including: a wide area communication unit configured to communicate with a server via a wide area network; a storage unit; and a short-range wireless communication unit configured to communicate with the movable object via a short-range wireless communication network. The updating software package is received, via the wide area network and the wide area communication unit, from a server including an updating software database storing the updating software packages for updating the software package of the control device. The updating software package received from the server is stored in the storage unit. The updating software package stored in the storage unit is transmitted to the movable object, via the short-range wireless communication unit and a short-range wireless communication network.
