摘要：The invention generally relates to an improvement of conventionalHydraulically Power Assisted Steering system (HPAS-system) arranged to supply asteering assist force to the steering assembly of a vehicle as a response to a torqueapplied by a driver to the steering wheel. In such HPAS-systems a certain drivers torque
always results in a certain assist force. The invention therefore discloses a valve that canbe actuated to dynamically alter the steering assist force produced by the HPAS-system.This makes it possible to dynamically adjust the assist force so that an appropriate forcemay be delivered to fit the specific driving scenario.
