PURPOSE:To prevent the control disturbance due to impulsive noises, etc. by discriminating whether the values of control data delivered sequentialy are within a prescribed range and delivering the data within a storage in place of the data whose value exceeds the prescribed range. CONSTITUTION:An internal-combustion engine apparatus 2 contains a controller 4 to which the speed data D1 showing the revolving speed of an internal-combustion engine 3 is fed along with the acceleration data D2 showing the manipulated amount of an acceleration pedal and the water temperature data D3 showing the temperature of the engine cooling water. This controller 4 delivers a control signal S1 for the engine 3 in order to obtain the engine speed corresponding to the operation state of each time in response to those input data. A rotary sensor 5 which detects the revolving speed of the engine 3 delivers a pulse train signal S2 to a signal processor 1. If the value of the data D1 shows some fault, a substitute data is delivered to avoid an input of the faulty data to the controller 4. |
