本文主要探討線控轉向系統車輛穩定控制，由於線控轉向系統是透過控制轉向馬達，因此可在其控制核心內加入車輛穩定控制之策略，使車輛能達到轉向之效果，同時也具備了車輛安全穩定之特性。在車輛轉向穩定控制中，其主要目的在於控制車輛之重心側滑角，使車輛在行駛時都能保持在最低的重心側滑角的範圍內，以增加車輛在低速或高速過彎時的安全性、操控性以及穩定性。
利用模擬軟體 CarSim 模擬測試，並觀察分析模擬車輛在行駛時是否能保持在最低的重心側滑角的範圍內。在透過硬體迴路 (HIL) 測試與本研究所建立的線控轉向平台相互連接控制，經由觀察硬體迴路測試之結果，可證實車輛穩定控制於平台上之控制。

This study focuses on the handling control of vehicles with steer-
by-wire systems (SBW).Vehicles with steer-by-wire systems get rid of
some of the limitations of traditional steering systems, which enhances
vehicle handling control.In vehicle handling control, the main purpose is to focus on sideslip angles at car-ground control. Under this control system, vehicles should always have minimal sideslip angles at the C.G. range, and have stable handling in high speed or low speed cornering.
First, we use the CarSim software to verify the proposed method for
the vehicle handling control. Next, the hardware-in-the-loop (HIL) is
connected to the steer-by-wire system platform and the controller of the
steering motor. Through the hardware-in-the-loop test result, we can
verify that the vehicle can obtain stable steering as the vehicle is cornering.
