Abstract

A method of estimating hydraulic flow in a steering system of an articulated vehicle (1), a controller (6) configured for the method and an articulated vehicle (1) are provided. The method comprises:a) sensing a yaw rate (θ̇) of the articulated vehicle (1);b) sensing a velocity (v) of the articulated vehicle (1);c) determining an estimate of a steering angle rate (δ̇) of the front part (2) of the articulated vehicle (1) using the sensed yaw rate (9) and the sensed velocity (v);d) determining an estimate of the hydraulic flow in the steering system of the articulated vehicle (1) using the estimate of the steering angle rate (δ̇) and one or more geometrical parameters of the steering system.
