Method for determining a centre position of a vehicle steering system

摘要

A method for determining a centre position of a vehicle steering system, comprises the steps of reading a plurality of predetermined inputs. The method includes the steps of roughly estimating a centre position of the vehicle steering system after the vehicle begins moving based upon the read predetermined inputs and determining whether the steering wheel of the vehicle steering system is approximately straight. The method further includes the steps of accurately estimating a centre position of the vehicle steering system if the steering wheel of the vehicle steering system is approximately straight and concluding that the accurately estimated centre position is the centre position of the vehicle steering system if the steering wheel of the vehicle steering system is approximately straight and Concluding that the roughly estimated centre position is the centre position of the vehicle steering system if the steering wheel of the vehicle steering system is not approximately straight.
