Commercial vehicle antilocking braking system

摘要

The braking system uses a differential stage providing a wheel accelerationor retardation signal from the wheel velocity signal. A signal is provided whenthe acceleration or retardation signal attains its extreme value, fed to a selection and storage circuit forming part of a prognosis stage providing a signal representing the optimum wheel velocity during braking. This signal is compared with the actual wheel velocity for providing the braking pressure regulator. The prognosis stage incorporates a control circuit providing a signal representing the variation intensity of the wheel velocity signal.
