PURPOSE:To prevent malprocessing of a signal, by detecting digital signals, outputted through control of a switch, at intervals of a given time and performing a processing by means of a signal produced in case a change amount attains within a specified range. CONSTITUTION:A control computer ECU, processing a digital signal outputted from an A/D converter through control of a switch, repeatedly detects in a sampling manner said signals at intervals of a given time T. The ECU computes a difference between a preceding sampling value ADn-1 and a present sampling value ADn, and in case the absolute value of the difference is within a specified value, K it is decided that the transient change of said signal is completed. The ECU starts to process the current digital signal and performs a given control operation indicated through control of the switch. |
