Experimental Determination of the Passenger Car Deceleration under Different Road Conditions

In this paper, the authors present an experimental study to determine the influence of the active safety system “ABS” on the braking deceleration of vehicles under different road surfaces and at different driving speeds. Different vehicles were used for the purpose of the experiment. The experiments were conducted in two stages. In the first stage of the experiment, the braking deceleration was measured with the “ABS” system running, at different speeds and road surfaces. In the second stage of the experiment, under the same conditions, the braking deceleration was measured with the “ABS” system deactivated. The purpose of this study is to analyse the influence of the “ABS” system on the braking deceleration under different factors in a real environment. A modern method for determining the braking deceleration by applying the ENERGOTEST EnergoSM 4.0 non-contact speed and acceleration measurement system.
