2088908 9203319 PCTABS00010 The regulator supply valve (100, 101, 200, 300, 400, 500, 600, 740) of the present invention provides regulated fluid pressure for adaptive braking and traction control systems (10, 710) operation. The regulator supply valve (100, 101, 200, 300, 400, 500, 600) and system (10) may be supplied as an add-on feature for a standard braking system. During adaptive braking system operation, pressure from a chamber (28, 30; 718, 716) of a master cylinder (12, 712) causes the regulator supply valve (100, 101, 200, 300, 400, 740) to communicate a pressure source (35, 720) with modulators (41, 42; 51, 52; 61, 62, 71; 746, 748, 752; 746', 748', 752') for respective wheel brakes (40, 50, 60, 70; 750, 760). During traction control operation an electronic control unit (201, 700) of the system (10, 710) activates a solenoid (104, 106; 204, 206; 304, 306, 404, 406; 504, 506; 604, 606; 783, 784) to cause the regulator supply valve (100, 101, 200, 300, 400, 500, 600, 740) to open controllably the communication between the pressure source (3, 720) and modulator valves (41, 42; 51, 52; 61, 62, 71; 746, 748, 752; 746', 748', 752'). The regulator supply valve (740) may alternatively be located within a boosted master cylinder (712) such that it is activated during both adaptive braking and traction control operation to enable the pressure source (720) to communicate with modulators (746, 748, 752; 746', 748', 752').
