Abstract: Apparatus, method and program product that controls the release of an electronically activated parking brake. An algorithm adjusts for cable stretch and limits the occurrence of over-release and wheel drag within the brake system. A controller monitors force incident on an actuator during a brake release operation. When a preset load is indicated, the controlling parameter of the algorithm transitions from force to position control. Once in position control, the controller uses previous position measurements and equipment specific constants to calculate a release point.

Abstract: An intelligent input push rod assembly for applying an input force from a brake pedal to a power booster of a brake system. The input push rod assembly includes a sensor that is capable of generating an electrical output having a magnitude that varies with the amount of force applied to the input push rod by the brake pedal. Preferably, the sensor generates an output voltage signal that is generally proportional to the input force applied to the input push rod. A shunt is provided so that springs associated with the sensor operate in a generally linear force-deflection operating range of the springs. The output signal generated by the sensor is applied to a brake light control system that is supported by the input push rod assembly. The brake light control system uses the signal generated by the sensor to determine whether the vehicle brake lights should be illuminated and also to cause direct illumination of the brake lights during a braking operation.

Abstract: A linear position sensor that includes a plurality of Hall effect transducers enables reliable positioning of a parking brake cable. Coarse positioning sensing is provided by longitudinally spacing the Hall effect transducers such that not more than one transducer has a positively sloped output signal for a given position of a magnet connected to a parking brake cable actuator. Fine position sensing is provided by linear approximation of the output signal with an offset appropriate for the specific transducer having the sensed positively sloped output signal.

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 vehicle roll control system including a torsion bar having a longitudinal axis and first and second end portions disposed along the longitudinal axis. A first arm includes a passive end fixed to the first end of the torsion bar and extending transverse to the longitudinal axis. A second arm is provided having an active end rotatably coupled to the second end portion of the torsion bar and also extending transverse to the longitudinal axis. The opposite ends of the first and second arms are each configured to couple to the vehicle chassis. An actuator including a cam locking element is provided for selectively locking and unlocking the active end of the second arm to thereby selectively prevent and allow rotation of the active arm relative to the torsion bar.

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.
