An engine control program is divided into an application layer and a platform layer. The application layer defines a program which is independent of a hardware and is provided under an object-oriented design. The platform layer defines a program which is dependent on the hardware and is provided under the object-oriented design, and divided into three layers, that is, an upper layer, an intermediate layer and a lower layer. The upper layer, intermediate layer and the lower layer includes a sensor/actuator layer, a device driver layer and a virtual MPU layer, respectively.
