IMPACT OF ANTI-LOCK BRAKING SYSTEM (ABS) ON VEHICLE BEHAVIOR DURING BRAKING

Abstract

The article presents experimental results on the study of the impact of the anti-lock braking system (ABS) on the stability of the movement and braking of the car. It is shown that the use of ABS reduces the braking distance (on dry pavement) by about 20%, and the braking time is reduced by 15.5%. In the absence of ABS, as a result of emergency braking, an uncontrolled skid of the car is observed, and the deviation from the initial direction of movement is from 30 to 45 degrees, depending on the initial speed of the car, the quality of the road surface, as well as the parameters and material of the tires. The emergence of adhesion and the dependence on motion factors are discussed. It is shown that the adhesion coefficient in the tests performed with ABS exceeded the coefficient of sliding friction in tests without ABS.
