Abstract:
A throttle valve controller for controlling the degree of opening of a throttle valve based on input signals outputted from at least first and second accelerator sensors for individually detecting the amount of depression of an accelerator pedal, comprising:failure detecting means for detecting failures in said first and second accelerator sensors by comparing each of the first input signal outputted from said first accelerator sensor and the second input signal outputted from said second accelerator sensor and predetermined upper and lower limit values;control signal computing means for computing a first control signal from the first and second input signals in response to the result of detection by said failure detecting means;control signal correcting means for effecting primary delay processing on the first control signal, thereafter restricting the so-processed signal to a guard value or less and outputting the signal therefrom as a second control signal; andthrottle control means for controlling the degree of opening of said throttle valve based on the second control signal.
