  • Publication number: 20190126975
    Abstract: An electric power assisted steering system comprises a first part that in use determines the sign of a first signal indicative of the position of a part of the steering, and a second part that in use determines the sign of a second signal indicative of the velocity of a part of the steering. A processing unit that in use determines whether the steering wheel is moving away from a centre position or returning to the centre position from the determined signs of the two signals, and sets a value of a torque damping component using different tunes for when the steering wheel is moving away from the centre and when term and when the steering wheel is returning to the centre. The processing unit may blend the two tunes when it detects a change in the direction of steering corresponding to a return to centre following movement away from centre or movement away from centre following a return to centre.
