DEVELOPMENT OF ANTI-LOCK BRAKING SYSTEMS OF MODERN CARS, INCLUDING ELECTRIC VEHICLES AND HYBRID VEHICLES

Abstract

The article provides an analytical overview of the development of automotive anti-lock braking systems (ABS). Some historical aspects of the development of automotive ABS are described. Examples of control algorithms for ABS actuators are given, which demonstrate the practical implementation of various control methods. The change of some technical characteristics of ABS and methods of their control is shown. Predictions are given for the development of anti-lock braking systems in the course of improving road transport and the transition from traditional cars with only an internal combustion engine to hybrid cars and electric vehicles. The experience of the FSUE “NAMI” is shown on the creation of ABS with combined actuators. The possibility of using electric drive machines for driving wheels to work as part of ABS actuators is investigated. Algorithms of joint control of friction braking mechanisms and electric machines have been developed. A set of theoretical and experimental studies of combined ABS actuators has been carried out, confirming the possibility of improving the braking characteristics of a car in various road conditions during emergency braking.
