Electronic Traction Control System ASR and its Integration in the Anti-Lock Braking Systems ABS to Form a Safety System “ABS/ASR” for Commercial Vehicles 881137

Systemized planning, increasing technological know-how and successful realization of electronic components suitable for use in commercial vehicles have considerably increased the technological standard of commercial vehicles over the last decade. Particular efforts were made to enhance traffic safety and relieve the stress on the driver through preventive measures on part of the vehicle. A primary consideration within the context of these objectives was the trouble-free controllability of acceleration and braking. It is thus possible to achieve a sufficient degree of lateral stability in the optimum wheel-slip range to guarantee not only the desired reduction in the demands on the driver, but also a high level of directional stability, steerability, shortest possible stopping distances and optimum tractional capacity under all tire-to-road adhesion conditions. The subject of this paper - traction control (ASR) with differential braking control and engine control - represents, in conjunction with the anti-lock braking system (ABS), a further step towards improving the active safety of commercial vehicles, and thus traffic safety in general.
