The invention relates to a method for determining the absolute angular position of a steering wheel (3) of a vehicle, said method involving an initial-estimate step (a) during which a first value (Angle1) indicative of the absolute angular position of said steering wheel (3) is evaluated by a first model based on analyzing a first vehicle running dynamic parameter, such as the speed differential of the wheels of one wheelset, a second-estimate step (b) during which a second value (Angle2) indicative of the absolute angular position of said steering wheel is evaluated by a second model based on analyzing a second dynamic parameter, such as the yaw rate, followed by a checking step (c) during which the difference between the first value (Angle1) and the second value (Angle2) is compared against a predetermined consistency threshold (S) in order to decide, through suitable weighting, whether said values are to be considered or excluded.
