How do Today's Modern Passenger Cars Brake?

Abstract

The article deals with issues of vehicle braking from different points of view. We made repeated braking tests of modern vehicles during intensive braking on various asphalt surfaces with the goal to evaluate character of this random variable. We dedicated our attention also to the accuracy attainable using various measuring methods and equipment. Within measurement of braking deceleration we used low-end measuring device (mobile smartphone) and measuring devices most used in Slovakia (XL Meter™ Pro Gamma). The collected data were processed in the software XL Vision and evaluated by SW PC-Crash 10.9. Usable result from article is mainly measurement set of braking deceleration of current modern vehicles during intensive braking on various asphalt surfaces as well as evaluation of accuracy levels with respect to various used devices.
