การศึกษาจุดศูนย์กลางมวลและสัดส่วนการเบรกที่ส่งผลกระทบต่อเสถียรภาพการบังคับยานยนต์ โครงการวิจัยย่อยที่ 3 การแปรผันของสัดส่วนแรงเบรกที่ส่งผลกระทบต่อเสถียรภาพการบังคับรถยนต์

The aim of this research is to study the brake proportional affected to vehicle stability. Braking performance and vehicle stability testing are the main of research purposes. Otherwise learning research center and new researcher in automotive engineering are the minor research objectives. The results of research discovered to the braking performance depend on driver behavior. By the minimum deceleration was appeared on the non-proportion in front axle with braking ratio 0:100. In term of vehicle stabilities yaw and pitch moment are normally occur by the driving behavior. But the sideslip is an absolutely effect to vehicle handling. With the braking ratio 100:0 there is the highest risk for controlling a vehicle cause of the wheels were locked-up condition in the rear axle. Therefore the value of the sideslip was exceeded with the criteria. Furthermore these project researches were got the learning research center and the new researcher in automotive engineering field.
