クシヨンコントロール装置。 A main throttle valve whose opening degree is controlled according to the amount of depression of the accelerator pedal and a sub-throttle valve whose opening degree is controlled independently of the accelerator pedal are arranged in series in the intake passage of the engine. By controlling the opening degree of the throttle valve,
In a traction control device that can control engine output torque independently of the accelerator pedal, the drive mechanism that drives the sub-throttle valve and the position of the sub-throttle valve in the fully closed direction are limited, and the A traction control device comprising valve closing position limiting means for ensuring a minimum air volume.
