The paper begins with an overview of the history of ABS for commercial vehicles followed by a brief description of the technology of the BOSCH ABS at the time it went into mass production in 1981. Subsequently it describes the field experiences with ABS including the experiences of drivers and operators. These experiences are reflected in the equipment which BOSCH offers today. Additional functions such as ASR (traction control) have been integrated. The paper provides an overview of the functions available today and their implementation. The paper concludes with a discussion on potential continued developments and an attempt to describe the systems which will be required by the mid 9os.

Electronic systems have been used in commercial vehicles for quite a few years now. At the start, this primarily related to consumer electronics equipment (car radio and CB radio), but, since the late 70s, electronic control systems have also been used for a wide variety of applications in commercial vehicles. This development went hand in hand with the development of digital microcontrollers. It was only when such powerful electronic circuits were developed that it was possible to implement complex control tasks at feasible cost with adequately compact design. Nowadays, an extremely wide variety of systems is offered for the engine, suspension, brakes, comfort and entertainment.
