METHOD AND APPARATUS FOR REAL TIME ESTIMATION OF ROAD SURFACE FRICTION COEFFICIENT

摘要

A computer program product, a method and an apparatus for detection of road surface friction coefficient for vehicle stability control are disclosed. The computer program product comprises stored instructions for receiving detected vehicle parameters from a vehicle; calculating a lookup value based on the detected vehicle parameters, the calculating comprising an recursive least square estimation; retrieving a road surface friction coefficient from a lookup table by matching the calculated lookup value to the road surface friction coefficient stored in the lookup table; calculating adjustments to the vehicle using the road surface friction coefficient; and outputting the adjustments to a vehicle control system for execution.
