Abstract

1301303 Antiskid braking systems AISIN SEIKI CO Ltd and SHARP CORP 24 Dec 1969 [26 Dec 1968 27 Dec 1968] 62923/69 Heading F2F An antiskid braking apparatus for a vehicle has first and second sensors 11, 12 and 10 responsive respectively to rotational speeds of front wheels 104, 105 and rear wheels 100, 101 a differentiator for producing a signal dependent on the angular acceleration or deceleration of the rear wheels. A control valve 16 coupled thereto for isolating rear brakes from a fluid pressure source when deceleration reaches a predetermined value, a first circuit connected to sensor 10 and to a device 15 responsive to vehicle deceleration for weighting the output signal of sensor 10 in accordance with vehicle deceleration, a second circuit for comparing the output of sensors 11, 12 with the weighted output signal of sensor 10 and to control a second valve to isolate the front wheel brakes from fluid pressure when the difference between the weighted output signal and the output signal of sensors 11, 12 reaches a preselected value. The device 15 responsive to vehicle deceleration comprises a pressure responsive resistor 112 upon which an inertia mass 109 exerts a pressure depending upon the instantaneous deceleration of the vehicle.
