Editing Dynamic steering response (section)

== Components ==

The main components of Dynamic Steering Response systems in automobiles are the control unit, [[sensor]]s, and the electric motor.<ref name=":2">{{Cite web|last=|first=|date=2020-01-22|title=HOW IT WORKS: WHAT IS VOLVO DYNAMIC STEERING?|url=https://www.volvobuses.com/en-en/news/2020/jan/what-is-volvo-dynamic-steering.html|url-status=live|archive-url=https://web.archive.org/web/20200929004041/https://www.volvobuses.com/en-en/news/2020/jan/what-is-volvo-dynamic-steering.html |archive-date=2020-09-29 |access-date=|website=Volvo Buses}}</ref> The control unit acts as the computer of the DSR unit and gives instructions to the electric motor. Instructions are determined by evaluating data from sensors to compute appropriate steering corrections.<ref name=":2" /> Sensors collect data such as current vehicle speed, turning angle, terrain conditions, [[crosswind]] acceleration, and torque applied to the steering wheel.<ref name=":2" /><ref name=":3">{{Cite journal|last1=Seo|first1=Ja-Ho|last2=Oh|first2=Kwang-Seok|last3=Noh|first3=Hong-Jun|date=2019-06-21|title=Model predictive control–based steering control algorithm for steering efficiency of a human driver in all-terrain cranes|journal=Advances in Mechanical Engineering|volume=11|issue=6|language=en|doi=10.1177/1687814019859783|s2cid=197447570|doi-access=free}}</ref><ref name=":4">{{Cite journal|last1=Pfeiffer|first1=Jens|last2=Rudibert|first2=King|date=2018-02-09|title=Robust control of drag and lateral dynamic response for road vehicles exposed to cross‑wind gusts|journal= Experiments in Fluids|volume=59|issue=3|page=45|doi=10.1007/s00348-017-2479-7|bibcode=2018ExFl...59...45P|s2cid=125804163|doi-access=free}}</ref> The [[electric motor]] is a device powered by electricity that adds torque in the form of mechanical energy to a steering gear(the gear responsible for translating the rotation of the steering wheel to the actual turning of a vehicle). After calculating necessary steering corrections, the control unit instructs the electric motor to apply the torque needed to the vehicle's hydraulic steering gear.<ref name=":2" /> For the motor's control, it picks up the data at 2000 times a second (as in Volvo truck FM Series) based on the input from the driver, and from the on-board sensors. Its purpose is to provide precise steering control in every situation.
