Abstract
The present invention relates to a method for controlling vehicle lane holding for a vehicle with an electric power assisted steering by means of a steering system () with a steering assistance actuator and one or more controllable vehicle state actuators comprising measurement of at least one vehicle position input signal with using an on-board vision system for determination of a relative vehicle lane position in the form of a lateral lane position, a heading angle and a lane curvature, transformation of the relative vehicle lane position to a target yaw and/or lateral vehicle state, measuring at least one steering input signal, determination from said one or more measured steering input signals a torque value applied by the driver via a steering wheel (), transformation of said torque value to a relative to the afore-mentioned target yaw and/or lateral vehicle state a driver target relative yaw and/or lateral vehicle state, adding said target yaw and/or lateral vehicle state and said driver target relative yaw and/or lateral vehicle state together, and using the resulting yaw and/or lateral vehicle state as a reference signal to one or more controllers for the mentioned control of the one or more vehicle state actuators.
