Abstract
An assisted power steering system and a method for assisting a turning of a steered wheel of a steering system comprising an energy source arranged to assist the turning of the steered wheel, a sensor arrangement arranged to detect direction of the turning, and a control unit arranged to control the energy source based on data from the sensor arrangement, wherein the sensor arrangement comprises at least one first digital sensor arranged to indicate the direction of the turning.

An assisted power steering system for assisting a turning of a steered wheel of a steering system comprising an energy source arranged to assist the turning of the steered wheel, a sensor arrangement arranged to detect direction of the turning, and a control unit arranged to control the energy source based on data from the sensor arrangement, wherein the sensor arrangement comprises a first digital presence sensor arranged to be in either an on-state or an off-state to indicate the direction of the turning.
A method for assisting the turning of a steered wheel of a steering system comprising the step of:
- turning a steering means, such as a tiller arm, steering wheel or the like, of the steering system;
- wherein comprising the steps of:
- detecting an angle difference of the steering means and the steered wheel by a digital presence sensor arranged to be in either an on-state or an off-state to indicate the direction of the turning;
- and
- assisting the turning of the steered wheel by providing a pre set turning force to the steered wheel from an energy source when said detection has been made and thereby reducing the angle difference.
