REGLERINGSANORDNING FOR ATT FORHINDRA LASNING AV FORDONSHJUL

摘要

An anti-skid or anti-wheel-lock system for motor vehicles in which a rotation sensor sends signals to a processor that determines if wheel lock is imminent and then sends brake force reduction control signals to a brake force controller. The control signals are first passed through a time filter having a plurality of discrete paths with differing signal constants. The selection of the filtering time constant is made by a circuit which measures the period between control signals against a reference time and changes the filtering time constant in accordance with the results of the measurement.
