Coefficient of friction confidence estimate and coefficient of friction combination

摘要

The invention relates to a method for a coefficient of friction confidence estimation and a coefficient of friction combination. The method comprises: providing a vehicle (101) comprising a set of road wheels (102); Providing a number of vehicle systems comprising a brake system that is configured to operate a brake set, a steering system that is configured to adjust a direction of a road wheel (102) and a drive system that is configured to apply a driving force to the road wheels (102) transfer; Providing a number of sensors or cameras (112); Providing a control unit (108) which is set up to process sensor and camera data; Providing a roadway that has an actual coefficient of friction; Using the sensors to determine a first estimated coefficient of road friction and an associated first confidence level; Using the sensors to determine a second estimated coefficient of road friction and an associated second confidence level; Using the control unit (108) to generate an adaptation signal and to communicate it to the vehicle steering system, wherein the adaptation signal is based on any estimated road friction coefficients and associated confidence levels, and using the vehicle systems to actuate the brake set, the steering system or the drive system in an adapted manner to the adaptation signal Wise.
