Method of and an apparatus for regulating an electrically regulated brake circuit of a multi-circuit brake mechanism

A method of regulating at least one electrically regulated brake circuit that forms a portion of a multi-circuit brake mechanism, said multi-circuit brake mechanism includes a plurality of brakes which respond to and are activated by a predetermined fluid pressure medium, said method comprising the steps of:

• (a) initiating a brake application by manipulating a brake activation mechanism;
• (b) said brake application mechanism emitting at least one first electric brake value signal and at least one pressure signal when it is manipulated;
• (c) communicating said pressure signal from said brake activation mechanism to a fluid pressure responsive brake circuit, a magnitude of said first electric brake value signal and of said pressure signal depends upon at least one of a force applied to said brake activation mechanism and a travel distance of at least one member of said brake activation mechanism in step (a);
• (d) measuring a brake value produced by said fluid pressure responsive brake circuit;
• (e) transforming said brake value measured in step (d) to a second electric brake value signal;
• and
• (f) at least regulating in part said electrically regulated brake circuit in a normal mode of operation by said second electric brake value signal and in an exceptional mode of operation by said first electric brake value signal.
