Traction Control for Commercial Vehicles

The antilock system (ABS) for commercial vehicles and buses has become increasingly popular since its market introduction in 1981. Several vehicle manufacturers already equip their vehicles with ABS as standard, instead of only if specifically requested, and have been doing so for some years now. The advantages of ABS have become clear during the 7 years of field operation; Increase in safety for all traffic participants. High system availability. Economy of vehicle operation

Increased Safety and Improved Comfort Thanks to Electronic Systems for Bus and Truck Applications

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.

Antilock Braking Systems (ABS) for Commercial Vehicles - Status 1990 and Future Prospects

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.

State of the Art and Future Prospects of Braking Control in Europe

The major progress in braking systems in the last years has been the introduction of ABS. Since literature regarding antiskid braking systems for commercial vehicles is available in growing numbers, the objective of this paper is to deepen the knowledge of components. In terms of ABS the different concepts of pneumatic pressure modulation valves and their advantages are compared. There is a discussion on further improvements in air brake systems, such as reducing of response time of pneumatic braking by means of an entirely new approach. The paper continues with traction control and deals with improvements of the efficiency of air compressors. Also the market of commercial vehicles is evaluated.

Automotive Electronics – What Makes it So Special?

Automotive electronics consists of advanced sensors, control units, and “mechatronic“ actuators forming increasingly complex, networked vehicle systems. The article shows typical requirements for automotive electronic systems and their components. While quantities are typically lower than in mainstream (consumer/telecommunication/computer) electronics applications, requirements regarding safety (flawless design), reliability and durability, operating conditions and temperature cycles, as well as long-term supply capability are much higher. As a consequence, automotive electronics is typically using well-proven technologies derived from mainstream electronics with some time delay regarding their introduction. In addition, automotive specific technologies have been developed for highly integrated control units and “mechatronic” actuators. Some recent examples are given. The paper closes with a vision regarding further developments and trends in Automotive Electronics.
