Abstract

The present invention relates to a method for determining hydraulic failure of an active hydraulic steering system (SS1) of a vehicle (V). Said steering system comprises a steering wheel (SW) connected to a wheel axle (X) with steerable wheels via a steering column (SC), a torque adjustment means (EPS) for providing a steering torque for adjusting steering, and a hydraulic power steering system (HPS1) for amplifying steering torque based on total steering torque provided by driver and said torque adjustment means (EPS). The method comprises the steps of: determining (112, 114, D1) said total torque; determining (122a, 122b) steering angle velocity and/or steering angle acceleration; processing (100) said determined total torque and said steering angle velocity and/or steering angle acceleration so as to produce a characteristic steering parameter value; and based on said characteristic steering parameter value determining whether a hydraulic failure of said hydraulic power steering system has occurred.The present invention also relates to a system for determining hydraulic failure of an active hydraulic steering system. The present invention also relates to a vehicle.
