According the English Wikipedia, an anti-lock braking system (ABS) "is a system on motor vehicles which prevents the wheels from locking while braking. The purpose of this is to allow the driver to maintain steering control under heavy braking and, in most situations, to shorten braking distances (by allowing the driver to hit the brake fully without the fear of skidding or loss of control)." This terms also has a number of interpretation in Vietnamese language, such as “thắng chống khóa bánh,” “thắng chống bó cứng phanh,” “thắng ABS” etc. But technically speaking, it is referred to as “hệ thống thắng chống hãm.”
