Research on the Pull Drift Compensation Control Algorithm based on Steer-By-Wire Systems

<div class="section abstract"><div class="htmlview paragraph">SBW(Steer-by-wire) is a steering system that transmits the driver’s request and gives feedback to the driver through electrical signals. This system eliminates the mechanical connection of the traditional steering system, and can realize the decoupling of the steering wheel and the road wheel. In addition, this system has a perfect torque feedback system, which can accurately and delicately feedback the road surface information to the driver.</div><div class="htmlview paragraph">However, vehicle driving deviation is one of the most common failure modes affecting vehicle performance in the automotive aftermarket, this failure mode can exacerbates tire wear, reducing their life cycle, at the same time, the driver must apply a counter torque to the steering wheel for a long time to maintain straight-line travel during driving. This increases the driver’s operational burden and poses safety hazards to the vehicle’s operation. Based on the steer-by-wire system and vehicle driving deviation characteristics, this paper proposes Pull Drift Compensation (PDC) function. This function is based on the identification of vehicle driving deviation conditions. Based on Hardware In Loop Test (HIL) platform for tuning and simulation verification.</div></div>
