ABSTRACT:
An automobile total traction control system comprises a primary traction control system utilizing at least one of a fuel-cut control and an ignition-timing control, a secondary traction control system utilizing a driving-force reduction control different from the fuel-cut control and the ignition-timing control, sensors for detecting a wheel speed of each road wheel to derive a slip rate of each drive wheel and detecting an engine condition such as engine load and engine speed, and a controller for determining an acceleration-slip state of the vehicle based on the derived slip rate. During acceleration-slip, the controller determines the control allocation between the primary and secondary traction control systems based on the detected engine load, such that the control allocation of the primary traction control system to the secondary traction control system is decreased in accordance with an increase in the detected engine load.
