An apparatus and method are provided for operating a pump-less rear wheel anti-lock brake system of a vehicle using speed sensors on at least one front and one rear wheel, to provide a true dynamic rear proportioning (DRP) function, and to significantly enhance braking performance in rear wheel anti-lock mode through better management of the volume of pressurized fluid supplied by the master cylinder using rear pressure control (RPC).

A park brake apparatus for a vehicle electric brake comprises an electric motor having a rotational output shaft coupled to a brake mechanism. Rotational movement of the electric motor in a first direction causes application of brake force in the brake mechanism and rotational movement of the electric motor in a second direction opposite the first direction causes release of brake force in the brake mechanism. An armature for the electric motor includes a plurality of radially extending armature arms. A solenoid has a plunger movable between extended and retracted positions. In the retracted position, the plunger is free of the radially extending armature arms and the armature spins free of the plunger. In the extended position, the plunger engages the radially extending armature arms, locking the armature in place and maintaining a park brake state.

A brake system control apparatus comprising: a fluid brake system including a master cylinder containing a hydraulic fluid having a hydraulic pressure, a hydraulic pump having an output hydraulically coupled to the master cylinder, a motor coupled to and providing motive force to the hydraulic pump, a current sensing device coupled to the motor and providing an output signal indicative of electric current through the motor; and an electronic controller coupled to the current sensing device comprising a first sampler taking a first sample of the output signal a first time period after a start up of the motor, a second sampler taking a second sample of the output current a second time period after start up of the motor and a divider for determining a ratio of the first and second samples wherein the ratio is indicative of a hydraulic pressure in the master cylinder at the start up of the motor.

An electromagnetic brake system includes a motor having a rotor with a rotatable disk fixed to the rotor and an electromagnetic brake disposed about the disk to selectively prevent rotation of the rotor. The electromagnetic brake is carried on a resilient element so that it is suspended relative to the disk and isolated from the remainder of the system reducing the propagation of structural and airborne noise generated by actuation of the electromagnetic brake.
