Abstract
A method, arrangement and system are described for estimating one or more vehicle cornering stiffness parameters (c, c) in a linear vehicle operating region. The method includes reading sensor data representative of at least vehicle () longitudinal velocity (v), vehicle lateral acceleration (a), vehicle yaw rate (ω) and vehicle steering angle (δ), determining from the read sensor data if the cornering stiffness parameters (c, c) are observable, and if so providing an estimate of the cornering stiffness parameters (c, c) using a bicycle model that includes a model of tire relaxation dynamics.
