Abstract
A control program for an electronic control unit includes interrupt processes, tasks and a real-time operating system which controls switching of tasks based on execution priorities. The control program designates the interrupt level as a mask level in a predetermined task, and has an interrupt prohibition interval in which an interrupt of the interrupt process of the lower interrupt level and switching of the tasks are prohibited. The control program is programmed not to execute a task scheduling process of the real-time operating system at an end of the interrupt prohibition interval under a predetermined condition in which it is not likely that the tasks are switched at the end of the interrupt prohibition interval.
