Patent number: 8936322Abstract: A system for use in a vehicle with a brake pedal and a brake circuit. The system includes a master cylinder assembly configured to pressurize fluid therein in response to movement of the brake pedal, a sensor assembly configured to generate a pedal position signal indicative of position of the brake pedal, an electronic control unit configured to (i) generate a brake request signal in response to generation of the pedal position signal, and (ii) generate a selector control signal, and a selector valve assembly being moved from a first mode to a second mode in response to generation of the selector control signal, the master cylinder assembly is (i) isolated from fluid communication with the brake circuit when the selector valve assembly is positioned in the first mode, and (ii) in fluid communication with the brake circuit when the selector valve assembly is positioned in the second mode.Type: GrantFiled: April 20, 2010Date of Patent: January 20, 2015Assignee: Robert Bosch GmbHInventors: Milan Klimes, Timothy J. Albert, Gregory P. Goodzey, Kevin Johnson, Kenneth S. Towers

Patent number: 8596061Abstract: An in-line brake system with a hydraulic booster includes a master cylinder defining a cylinder bore, a master cylinder piston located within the cylinder bore, a transfer piston located within the cylinder bore rearwardly of the master cylinder piston, a transfer piston actuator with a first seat, a sealing member aligned with the first seat, a sealing member spring operably connected to the sealing member and the transfer piston, an input rod aligned with the first seat, a return spring operably connected to the input rod and the transfer piston actuator, a sleeve actuator located within the cylinder bore rearwardly of the master cylinder, and a sleeve spring configured to bias the sleeve actuator away from the master cylinder piston, wherein the sleeve actuator is configured to bias the transfer piston toward the master cylinder piston in response to an applied boost pressure.Type: GrantFiled: July 15, 2010Date of Patent: December 3, 2013Assignee: Robert Bosch GmbHInventors: Timothy J. Albert, Gregory P. Goodzey, Kevin K. Johnson

Patent number: 8573708Abstract: A hydraulic braking system for use in a vehicle employing both hydraulic and regenerative braking including a master cylinder with a reservoir inlet port and an outlet port. The outlet port is responsive to vehicle operator applied brake pedal pressure to close the inlet port and provide pilot pressure at the outlet port which is selectively coupled by a valve (57) to a hydraulic pedal simulator and to a control valve. The control valve provides boost hydraulic pressure from a pressure source to a vehicle wheel brake actuator in proportion to the pressure differential between the pilot pressure and a hydraulic pressure which is proportional to regenerative braking torque. This allows the power train controller to independently request different levels of regeneration on the two axles.Type: GrantFiled: June 23, 2008Date of Patent: November 5, 2013Assignee: Robert Bosch GmbHInventors: Gregory P Goodzey, Roger W Miller

Patent number: 4979398Abstract: A direct acting circuit through which the torque to which a shaft is being subjected is measuring without the need for divisions or other computer assisted computations. The system is self-clocking and counts speed dependent pulses generated by shaft rotation alternately in incrementing and decrementing modes with the difference being indicative of the torque. The count may be averaged over one or more complete shaft rotations to reduce or eliminate errors due to shaft or rotation sensor irregularities.Type: GrantFiled: September 28, 1989Date of Patent: December 25, 1990Assignee: Allied-Signal Inc.Inventors: Gregory P. Goodzey, Steven R. Masteller, William C. Hutter

Patent number: 4722094Abstract: A device for measuring the rate of change of speed of a machine such as a turbine engine which includes a digital counter for counting a speed signal having a frequency proportional to engine speed for a predetermined period of time and decrementing said count for a second period of time with the counting periods being proportional to engine speed. The up and down counts are derived by dividing a fixed frequency clock signal by a number proportional to engine speed to generate a variable frequency signal which frequency is proportional to engine speed. The difference between the up and down counts generates a remainder signal which is compared to predetermined limits.Type: GrantFiled: December 16, 1985Date of Patent: January 26, 1988Assignee: Allied CorporationInventor: Gregory P.
