Abstract
In an electronically controlled braking system which incorporates anti-lock brake control and includes a plurality of brake pressure control valves having associated local electronic control units which communicate with a master electronic control unit, part of the anti-lock brake control logic for a wheel is performed by the electronic control unit associated with the pressure control valve for that wheel, with the remainder of the anti-lock brake control logic for that wheel being performed by the master electronic control unit. The local valve-associated electronic control unit includes skid detection logic which causes the brake pressure at the associated wheel to be reduced in response to a wheel skid detected thereby, brake pressure at that wheel being controlled thereafter, at least for a defined period, according to demands communicated to the local control unit from the master control unit.
