Title: Anti-lock braking control system
IPC: B60T8/1763
Filed: 1974-10-03
Abstract: 1481733 Antiskid braking systems WABCO WESTINGHOUSE GmbH 3 Oct 1974 [3 Oct 1973] 43031/74 Heading F2F In an antiskid braking system including at least one device associated with one or more wheels and generating signals indicating when wheel acceleration or deceleration exceeds a predetermined threshold and brake pressure control means responsive to such signals to reduce the pressure when the deceleration threshold is exceeded and hold the pressure constant when the acceleration threshold is exceeded, a further signal is generated when the rotational acceleration exceeds an additional threshold if the wheels are on a road surface having a low coefficient of friction. A wheel driven generator G supplies an A.C. signal to a frequency to voltage converter FSU from which the direct voltage produced is applied via a lead 1 to a circuit producing a slip signal and to a differentiating circuit D. Threshold circuits not shown produce signals + b and - b representing acceleration or deceleration exceeding a threshold value. The output of circuit D is also applied to an additional threshold circuit 2 reponding to a lower acceleration then for the formation of signal + b. In operation the - b signal causes the closure of the brake cylinder inlet valve via an OR-gate 19 and the exhaust valve is opened by energization of solenoid 18 via an OR-gate 21. Brake pressure falls until wheel deceleration falls below the threshold and the - b signal ceases, the exhaust valve then closing and the inlet valve remaining closed so that pressure remains constant. The wheel accelerates and if a + b signal is produced an OR-gate 20 has an output applied via a delayed release circuit 26 and AND-gate 27 to OR-gate 19 to maintain the inlet valve closed. As signal +b terminates AND-gate 23 is no longer blocked, gate 27 is blocked by its output and after a delay imposed by a circuit 28 the valves return to normal. If however there is a sudden change in road coefficient of friction a signal +b is applied, after a delay imposed by a circuit 6, via an OR-gate 4 to control logic unit 5.
