ABSTRACT:
A traction control system for an automotive vehicle housing device for adjusting the driving torque delivered to driven wheels from an automotive internal combustion engine, and sensor for detecting vehicular deceleration and acceleration for generating a vehicular deceleration and acceleration indicative data. The system also performs the functions of monitoring the torque transmitted between a road surface and the driven wheel, generating a transmitted torque magnitude indicative data, and predicting road friction level on the basis of the vehicular deceleration and acceleration indicative data and the transmitted torque magnitude indicative data. Based on the road friction level, the system derives a torque criterion on the basis of the raod friction level. The system performs traction control in response to the transmitted torque magnitude indicative data greater than the torque criterion.
