Estimating the Tire-Road Friction Using a Nonlinear Observer Designed with the Parameter Identification Results of LuGre Tire Model

摘要：

In this paper we present a novel nonlinear observer structure for estimating the tire-road friction force under different tire-pressure conditions by use of the friction parameters identification results of LuGre tire model based on ant colony algorithm (ACA)with high precision.The observer developed here is shown feasible for the simplified motion dynamics of a quarter-vehicle model.Simulation resuits show its reasonableness.
