A modernised prototype system to control the slip of driving wheels (ASR) for vehicles with pneumatic braking system

Abstract

The paper presents the construction of an ASR system that is to control the slip of driving wheels of a vehicle by making use of the construction, function and operation of the pneumatic braking system and the pneumatic suspension control equipment. The essence of the solution presented is the use of the piston-spring part of the spring brake chamber as an actuator in the anti-slip regulation system. In the modernised version of the prototype, the system is controlled by means of a pneumatic solenoid valve, which performs the functions of an ASR modulator. The above concept may be implemented in trucks, buses, or other vehicles provided with pneumatic braking systems. The prototype ASR system proposed was verified by computer simulation tests.
