Abstract: A controlled brake apparatus and method of operating a brake apparatus utilize a pre-charge circuit connected directly between the fluid reservoir of a master cylinder of the apparatus and the inlet of a controlled braking pump, to thereby direct pre-charge flow and pressure to the controlled braking pump inlet in a parallel circuit relationship to a primary hydraulic circuit, rather than in a series flow arrangement through the primary hydraulic circuit as was the case in prior brake systems. The pre-charge circuit includes an integral back-flow check valve, and an accumulator.

Abstract: A power booster for a brake system including a housing having an interior and a pair of diaphragms separating the interior of the housing into three chambers. A power piston assembly is coupled for movement with the diaphragms and includes an output member. A reaction member is coupled to the power piston assembly, and an input member is adapted to be coupled to a movable brake pedal. An air valve assembly moves between open and closed positions to selectively admit atmospheric air into selected ones of the chambers. This induces an output force on the diaphragm that is transferred to the output member of the power piston assembly. The triple booster adds an additional working chamber with an added approximately 45% increase in power boost. The triple power booster retains many of the same components as prior dual or tandem boosters to provide an economical solution to increase booster output without the need for new tuning procedures or added booster diameter.

Abstract: A power booster for a brake system including a housing having an interior and a diaphragm separating the interior of the housing into at least two chambers. A power piston is coupled for movement with the diaphragm and includes an output member. A reaction member is coupled to the power piston, and an input member is adapted to be coupled to a movable brake pedal. An air valve assembly moves between open and closed positions to selectively admit atmospheric air into at least one of the chambers. This induces an output force on the diaphragm that is transferred to the output member of the power piston. The air valve assembly includes a portion adapted to engage the reaction member in response to an input force applied to the input member and is length adjustable between the input member and the reaction member. The air valve assembly operates at a first length when an input force is applied to the input member at a first rate and the air valve assembly operates at a second length shorter than the first length when an input force is applied to the input member at a second, higher rate. This lowers the input force needed to maintain a constant output force.

Abstract: A hydraulic pressure intensifier for operating a vehicle braking system under conditions that are not conducive to the proper operation of a power assist for the braking system. The hydraulic pressure intensifier has an intensifier inlet fluidly connected to a master cylinder and an intensifier outlet fluidly connected to a wheel cylinder. A bypass valve has an input and output fluidly connected to the intensifier inlet and the intensifier outlet, respectively. With normal power assisted braking operation, the bypass valve is open and the master cylinder is fluidly connected to the wheel cylinder via the bypass valve. In a manual or nonpower assisted braking operation, the bypass valve is closed; and the hydraulic pressure intensifier is fluidly connected between the master cylinder and the wheel cylinder. Thus, with the bypass valve closed, a fluid pressure from the master cylinder that is applied to the inlet of the intensifier cylinder is multiplied to a greater fluid pressure at the outlet of the intensifier cylinder and applied to the wheel cylinder.

Abstract: A method is directed to controlling an electric caliper brake system. The method provides for receiving an ignition voltage signal, receiving a caliper position signal, sending a motor shut down signal, sending a back drive control signal based on the received ignition voltage signal and the caliper position signal, and releasing stored energy from a non-linear device to a caliper brake system motor responsive to the back drive control signal. The non-linear device may be implemented as a capacitor. The step of sending a back drive control signal based on the received ignition voltage and the capacitor position signal includes analyzing the ignition voltage signal for an ignition voltage failure, analyzing the caliper position signal for caliper engagement, and transmitting the back drive control signal responsive to the ignition voltage failure and caliper engagement. Ignition voltage failure occurs when the ignition voltage signal is a low value.
