Abstract
A throttle control apparatus for use with an automotive internal combustion engine. The apparatus assures that the drive wheels are stopped from spinning on a snowy road surface if the driver pushes down on the accelerator pedal. The apparatus comprises an accelerator operation mechanism including the accelerator pedal, a first throttle-driving means capable of opening and closing the throttle valve, a controller, a second driving means, and a fuel-cutting means. The first throttle-driving means is mounted independent of the accelerator operation mechanism and includes a driving plate, a clutch plate, and a movable yoke. The controller controls the first throttle-driving means to adjust the throttle opening. When the first throttle-driving means becomes inoperative, the throttle valve can be driven by the accelerator operation mechanism via the second throttle-driving means. The fuel-cutting means is operated when excessive spin of the drive wheels is detected.
