VEHICLE CONTROL DEVICE

In the present invention, when an abnormality occurs in a task, regardless of whether a critical section is being executed, timeout detection is realized by determining whether the critical section (CS) is necessary for the design in a preset task execution time and a certain period of time to distinguish between necessary interrupt disable and abnormal interrupt disable. A vehicle control device includes task execution means for causing a system to execute a task, and interrupt processing means for performing an interrupt process at the time of execution of the task. A maskable interrupt and a non-maskable interrupt that is commanded to execute after the maskable interrupt are included, the maskable interrupt is commanded to execute during an interrupt disable time, and then the non-maskable interrupt is executed.
