DEVICE, METHOD, AND PROGRAM ANALYSIS OF NEW SOURCE CODE TO BE ADDED TO EXECUTION PROGRAM TO CHECK FOR BUG

An application list reading part 220 reads an application list 122. An application collecting part 230 acquires a source code 111 of an installed application indicated by the application list 122. The application collecting part 230 also acquires a source code 111 of an additional application. A program analyzing part 240 performs program analysis concerning a new execution program 123 using the source codes 111. If a bug will not occur in the new execution program 123, a program creating part 250 creates a new execution program 123. Then, a program updating part 260 writes the new execution program 123 to an electronic control device 121 and adds an additional application name to the application list 122.
