Abstract
An automobile traction control system in combination with a throttle control system of an internal combustion engine for controlling traction of drive wheels, comprises a sub-throttle for adjusting an engine-power by varying its opening amount and a controller responsive to a slip amount of the drive wheel for controlling the sub-throttle opening to reduce an engine-power irrespective of an accelerator pedal work when the slip amount exceeds a predetermined threshold. To effectively suppress undesired acceleration-slip for example when starting on a low-.mu. road, the controller performs a sub-throttle slow-opening control under a particular condition of at least a low vehicle speed, a low-.mu. road and a great depression of an accelerator. During the slow-opening control, the sub-throttle opening increases slowly, after once adjusting the sub-throttle opening essentially to zero irrespective of the slip amount of the drive wheel.
