Abstract
A method is provided for measuring an absolute steering angle Φ of a steering shaft for a vehicle, using a first rotatable body that rotates together with the steering shaft of the vehicle at a predetermined rotation ratio. The method includes obtaining a Ψ' value by measuring a relative rotational angle Ψ′ of the first rotatable body using an angle sensor having a measurement range of Ω. The method also includes obtaining a present value for a frequency i-value of the first rotatable body by comparing the present Ψ′ value to a previous Ψ′ value. The method also includes obtaining a present value for a absolute steering angle Φ1 of the steering shaft from a present value for an absolute rotational angle Ψ of the first rotatable body by using the Ψ′ value and the present i-value.
