  "textContent": "[Problem] An object of the present invention is to provide a control apparatus of on-vehicle electronic equipment that monitors execution time of a control program of the on-vehicle electronic equipment by a shorter time unit, and in the case that execution time abnormality of a processing obtained by subdividing the control program is detected, continues a control processing of the on-vehicle electronic equipment by replacing the above processing with a simple alternative processing in the next period. [Means for solving the problem] A control apparatus of on-vehicle electronic equipment that monitors an execution time of each normal processing obtained by subdividing a control program of the on-vehicle electronic equipment by means of an MCU which is provided in the control apparatus, wherein in a case that an abnormality in the execution time of the normal processing is detected by a timer interruption processing based on a general-purpose timer built in the MCU and software, an alternative processing to be paired with the normal processing is performed to continue a control of the on-vehicle electronic equipment by replacing the normal processing with the alternative processing in a next period.",
