Abstract
1,231,430. Anti-skid brake systems. AUTOMOTIVE PRODUCTS CO. Ltd. 3 Dec., 1969 [10 Dec., 1968], No. 58669/68. Heading F2F. In an anti-skid vehicle braking system a reference or datum for anti-skid control of the brakes associated with the driven wheels is derived from an electrical analogue of the speed of at least one undriven wheel, under control of a simple antilock system. A four wheel vehicle has two undriven wheels A1, A2 and two driven wheels B1, B2 each pair of wheels having a speed transducer 1 or 3 such as a tacho generator for producing signals V U , V D respectively of which the signal V U is applied to the input of a signal generator 2, which provides a reference signal V R derived from the undriven wheels when subjected to the antilock cycle, and to the input of an electronic skid sensor unit 4 operable at a predetermined undriven wheel deceleration value to produce an output signal on line 5 for the energization of brake release solenoid S1 which is associated with mechanism (not shown) for effecting a fluid pressure reduction in the braking system for the undriven wheels. The signal V R together with signal V D and a bias voltage V B are applied to the inputs of a comparator device 6 which is arranged to produce an output signal on line 7 when /V D +V B /</V R / to effect energization of brake release solenoid 52 to release the brakes in the driven wheels.
