ABSTRACT:
A traction control apparatus for carrying out a traction control process of an automotive vehicle in order to control a throttle position of a throttle valve. The apparatus includes: a feedback control part for performing a feedback control process to adjust a throttle position of a sub-throttle valve based on a slip ratio of driving wheels of the vehicle, so as to prevent the vehicle from undergoing excessive slippage at the driving wheels when the vehicle is accelerating; an inhibiting part for setting the throttle position of the throttle valve to a first value by inhibiting the performing of the feedback control process when a traction control process is started; a first control part for enabling the inhibiting part to inhibit the performing of the feedback control process until a slip ratio convergence is detected; and a second control part for setting the throttle position of the throttle valve to a second value smaller than the first value when the driving wheel slip ratio is not converging after the throttle position has been changed to the first value at the start of the traction control process.
