Anti-Lock Brake Systems— Field Experience on Passenger Cars

The addition of anti-lock control to vehicle braking systems represents a considerable increase in complexity in design, development and manufacturing. Related to these three activities there is much to be learned from laboratory and prototype vehicle test programmes. When vehicles are in the hands of drivers who are representative of customers and operate in the real environment, however, there is a variety of valuable lessons to be learned about the acceptance and the acceptability of a system, both in relation to the vehicle and to usage by people who are not conditioned by their employment as vehicle or brake engineers. This paper discusses some of those lessons.
