Abstract
This invention detects deviations from design without hindering the real-time nature of interrupt processing, and assists in analyzing the impact of faults caused by unintentional interrupt processing, with the goal of curbing erroneous detection. In order to resolve this problem, this vehicle control device comprises; a deviation determination unitwhich determines if execution timing of an execution body has deviated from design settings, and transitions to a monitoring state; and a run-time verification unitwhich verifies the impact of deviation at timing which differs from that of the interrupt processing.
