Patent number: 10343660Abstract: A vehicle includes at least one brake assembly configured to brake at least one wheel of the vehicle in response to an applied voltage. A power supply is in signal communication with the at least one brake assembly. The power supply is configured to operate in a first mode that outputs a first voltage and a second mode that outputs a second voltage greater than the first voltage. A brake control system is in signal communication with the at least one brake assembly and the power supply. The brake control system is configured to determine a driving state of the vehicle, and is configured to output a brake boost request signal to initiate the second mode of the power supply in response to detecting the driving state, wherein a braking response time of the at least one brake assembly is improved in response to applying the second voltage.Type: GrantFiled: May 15, 2017Date of Patent: July 9, 2019Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Michael D. Rizzo, Mark J. Rychlinski, Paul S. Shaub, Anthony J. Rifici, Phanu Amatyakul

Publication number: 20160244039Abstract: A vehicle includes an engine, an accelerator pedal, transmission, transfer case, mode selection device, road wheels, an electronic brake assembly, and a controller. The transfer case is connected to the transmission, and is operable for establishing a predetermined transfer case mode. The mode selection device receives a requested crawl mode of the vehicle in the predetermined transfer case mode. The electronic brake assembly has a brake motor and brake calipers, with each brake caliper disposed proximate a respective wheel to brake the respective road wheel. The controller is programmed to simulate a four-wheel drive-low mode of the transfer case in response to the requested crawl mode by decelerating the vehicle via control of the brake assembly and limiting a gear state of the transmission to 1st or 2nd gear. An auto-hold state may be engaged in crawl mode when the vehicle stops to prevent rolling of the vehicle.Type: ApplicationFiled: July 9, 2015Publication date: August 25, 2016Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Michael D.

Patent number: 9316278Abstract: A brake pad life monitoring system can monitor the wear of a brake pad operatively coupled to a rotor. The brake pad life monitoring system includes an erodible, electrically non-conductive covering layer operatively coupled to the brake pad such that wear of the erodible, electrically non-conductive covering layer corresponds to the wear of the brake pad. Further, the brake pad life monitoring system includes an electrical circuit having a circuit path from a power supply to a ground. The electrical circuit is at least partially disposed on the erodible, electrically non-conductive covering layer and includes a first resistor connected in series with the power supply and a second resistor electrically connected in parallel with the power supply. The brake pad life monitoring system additionally includes a measuring device electrically connected to the electrical circuit.Type: GrantFiled: December 2, 2013Date of Patent: April 19, 2016Assignee: GM Global Technology Operations LLCInventors: Joseph K. Moore, Mauricio Vazquez Camarena, Stacey M. Blundell, Paul S. Shaub, Phanu Amatyakul

Publication number: 20120199214Abstract: A brake modulator is disclosed herein. The brake modulator includes, but is not limited to an electronic-brake-control-modulator portion including a processor and a hydraulic portion associated with the electronic-brake-control-modulator portion. The hydraulic portion includes a primary circuit extending through the hydraulic portion to receive hydraulic brake fluid. The hydraulic portion also includes a secondary circuit extending within the hydraulic portion to receive the hydraulic brake fluid. The secondary circuit is in fluid communication with the primary circuit. The hydraulic portion further includes a valve between the primary circuit and the secondary circuit. The valve is electronically actuatable and controls movement of fluid between the primary circuit and the secondary circuit. The processor is operatively coupled to the valve and configured to perform an automatic cycling of the valve in response to an actuating event during assembly of the vehicle to evacuate the secondary circuit.Type: ApplicationFiled: February 9, 2011Publication date: August 9, 2012Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Josef MACK, Raymond J.

Patent number: 7532966Abstract: A torque steer compensation algorithm utilizing selected vehicle parameters, such as for example engine torque, accelerator pedal position, throttle position, transmission gear, and vehicle speed. Rates of change of the parameters are determined and compared to predetermined thresholds, whereby a torque steer factor is determined. The resulting torque steer factor is subsequently multiplied with a conventional, prior art predicted steering assist signal to arrive at a modified steering assist signal which is output to the coil of the steering column to reduce driver perception of torque steer at the steering wheel.Type: GrantFiled: August 20, 2004Date of Patent: May 12, 2009Assignee: General Motors CorporationInventors: Stacey M.
