[Problem] An object of the present invention is to monitor an execution state of a control program of an on-vehicle electronic equipment in the control of the on-vehicle electronic equipment and enable to continue the control of the on-vehicle electronic equipment even in the case that an abnormal execution state is detected in the control program. [Means for solving the problem] The present invention provides an apparatus and a method that comprise a program execution monitoring dedicated circuit 110 connected to a CPU of a control apparatus of an on-vehicle electronic equipment that is comprised of an execution time monitoring timer circuit 111, an execution sequence monitoring comparison circuit 113, a setting register 115, an other attached circuit 117, perform monitoring of an execution sequence of a task executed by a control programof the on-vehicle electronic equipment and/or an execution time of the task executed by the control program, and enable to continue the control of the on-vehicle electronic equipment such as an electric power steering apparatus by performing an alternative processing in the case of detecting an abnormality in the execution sequence and/or the execution time.
