Abstract
A vehicle ECU (Electronic Control Unit) has a main microcomputer and an auxiliary microcomputer, with the main microcomputer periodically executing a processing routine for calculating values such as degrees of throttle opening of the vehicle engine based upon the current operating condition of the engine, wherein the main microcomputer generates resource inspection data during each execution of the routine and transmits the resource inspection data to the auxiliary microcomputer, with the resource inspection data including for example respective checksums for values calculated in successive steps of the routine and information indicating whether all steps of the routine have been actually executed, and with the auxiliary microcomputer monitoring the operation of the main microcomputer based upon the received resource inspection data.
