fahrregelsystem for a motor vehicle with the property prediction of the friction coefficient of the road.

摘要

A traction control system for an automotive vehicle comprises means for adjusting driving torque delivered to driven wheels from an automotive internal combustion engine, and means for detecting vehicular deceleration and acceleration for generating a vehicular deceleration and acceleration indicative data. The system also have means for monitoring a torque transmitted between a road surface and the driven wheel for generating a transmitted torque magnitude indicative data, and means for 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 road friction level derived by the fourth means. The system performs traction control in response to the transmitted torque magnitude indicative data greater than the torque criterion, for performing to control the first means for adjusting output torque of the engine and whereby adjusting the the torque transmitted between the road surface and the driven wheel below the torque criterion.
