Abstract
In a throttle control system including electrical elements or devices, if trouble occurs in these elements, there exists a problem in that the throttle valve is further driven forcibly in spite of the fact that the throttle valve has already been fully closed or opened. To overcome the above problem, a throttle valve close-limit switch and a throttle valve open-limit switch are additionally provided for the accelerator control system, in order to generate an alarm signal or a system disabling signal in the case where the difference between the target throttle opening rate and the actual throttle opening rate exceeds a predetermined value when one of the limit switches is on.
