Anti-skid brake control system with feature of derivation of precise projected vehicle body speed data utilizing longitudinal acceleration exerted on vehicular body

摘要

An anti-skid brake control system comprises a limiter which provides upper limit of variation of wheel speed indicative data. The limited wheel speed indicative data is derived with respect to each wheels. One of the greatest limited wheel speed indicative data is selected as vehicle body speed indicative initial data. The anti-skid brake control system derives a projected vehicle body speed indicative data by adding an integrated value of a longitudinal acceleration to the aforementioned vehicle body speed indicative initial data. The integrated value is provided a predetermined offset value for compensating error caused in a longitudinal acceleration sensor.
