Abstract
A traction control system for motor vehicles in which the occurrence of on-driving wheel speed is monitored during a time interval which begins when the traction control starts to a predetermined time period which elapses therefrom. In the event that no occurrence of no-driving wheel speed is detected during the aforementioned time interval, the throttle opening degree command value prevailing at the end of the time interval is decreased to a predetermined lower limit value in response thereto, while at the same time the control is changed to a low friction coefficient control mode.
