Abstract:
1. An antilock brake system for use in a wheeled vehicle having associated with each of a plurality of wheels a self-energizing brake system having hydraulically interconnected actuators that act on an eccentric rotor to generate a brake force and a brake exciter that provides for operating the actuators between a first position not in engagement with the eccentric rotor and a second position in engagement with the eccentric rotor, the antilock brake system comprising: a plurality of wheel speed sensors, each one connected to one of the plurality of wheels such that it can sense rotation of the wheel and generate a speed signal representative of the speed of rotation of the wheel; a control module that can receive said speed signal from each of said plurality of wheel speed sensors, can apply pre-determined algorithms to said speed signals to determine when any of the wheels is in a state of immanent brake lock-up and can generate a control signal for a wheel that is in a state of immanent brake lock-up; and a plurality of brake disengagement modules, each one associated with a self-energizing brake system, that can, responsive to said control signal received from said control module, cause the exciter to operate the actuators into the first position not in engagement with the eccentric rotor; wherein cyclic generation of said control signal by said control module provides for regulation of braking forces generated by the self-energizing brake system.
