An electro-hydraulic steering system for a vehicle and a method for limiting the steering angle of the electro-hydraulic steering system

Abstract

An electro-hydraulic steering system (2) for a vehicle has a control unit (24) configured to carry out a method for limiting the steering angle of the electro-hydraulic steering system (2) by method steps for estimating a driving speed of the vehicle (1), determining a maximum steering angle threshold (αmax) in dependence of the estimated driving speed of the vehicle (1), determining an automatic steering angle (αG) in response to an automatic steering demand, controlling a fluid flow provided by an electro-hydraulic valve (29) of the electro-hydraulic steering system (2) for controlling a hydraulic steering actuator (14, 15) connected with a steered wheel (17, 19) to adjust a steering angle (α18) of the steered wheel (17, 19) according to the automatic steering angle (αG) and limiting the automatic steering angle (αG) to the maximum steering angle threshold (αmax).
