Friction Detection from Stationary Steering Maneuvers

The friction coefficient between the tires of a vehicle and the roadway is one of the most critical parameters governing a vehicle's motion. However, most techniques for identifying road friction from vehicle motion require the operation of the vehicle in highly dynamic maneuvers that utilize a significant portion of the tire grip capacity. Thus, the excitation of dynamics sufficient to provide a reasonable estimate of the friction coefficient could also destabilize the vehicle. This paper presents an alternative approach to friction estimation wherein stationary steering maneuvers, such as those performed while exiting a parking space or at an intersection, may be used to identify the tire-road friction characteristics prior to higher speed operation. The paper describes a model and results from using a stationary steering process to identify friction. The approach is validated with experimental data from a steer-by-wire test vehicle to illustrate the efficacy of the technique.
