Abstract

A vehicle control program has a platform program as a program including a device driver for making a computer execute processing for inputting data from a hardware device and transmitting data based on the input result to another processing. The control program also has a coupling processing section as a program for making the computer execute processing for mediating the data acquired by the processing using the platform program so as to be adapted to processing using an application program. The control program further has the application program as a program for making the computer execute processing based on the data acquired by the processing using the platform program.
