Abstract
The leading automotive manufacturers have attempted to apply active brake systems to passenger and commercial vehicles. The ESC (electronic stability control) system helps drivers to maintain directional stability and control over steering and under steering. Previous studies on passenger vehicle ESC systems have mainly dealt with the control algorithm and evaluation results. In addition, few papers have considered bus and commercial ESC systems. Therefore, this study proposed a method for estimating the desired yaw rate using the already developed ESC system. The desired yaw rate is estimated from the steering wheel angle, vehicle speed, and vehicle parameters. This paper presents the results of a sine with dwell evaluation analysis of a large bus equipped with an ESC system. Through this process, we are able to estimate the ESC control strategy of the leading producer of commercial buses based on an air brake system. The bus ESC evaluation results can be used as a reference for the development of the ESC control algorithm.
