Abstract
The throttle valve controller 1 includes a failure detecting device 11 for detecting failures in the first and second accelerator sensors 2 and 3 based on the first input signal VAPS1 outputted from the first accelerator sensor 2 and the second input signal VAPS2 outputted from the second accelerator sensor 3. A control signal computing device 12 computes a first control signal T1 from the first and second input signals in response to the result of detection by the failure detecting device 11. A control signal correcting device effects primary delay processing on the first control signal T1, thereafter restricting the so-processed signal to a guard value or less and outputs the signal therefrom as a second control signal VAPS. A throttle control device 14 controls the degree of opening of the throttle valve 9 based on the second control signal VAPS.
