Patent number: 8912754Abstract: A system for charging an electrically powered vehicle comprises a DC battery; and a current exchange controller. The current exchange controller is configured for receiving a supply current from an off-board power source and determining a desired current exchange characteristic. The current exchange controller is also configured for determining a modulation scheme for providing an exchange current that exhibits the desired current exchange characteristic; and modulating the exchange current in accordance with the modulation scheme so as to deliver an exchange current exhibiting the desired current exchange characteristic. The modulation scheme is configured to meet one or more criteria based on annoyance.Type: GrantFiled: November 22, 2011Date of Patent: December 16, 2014Assignee: GM Global Technology Operations LLCInventor: Richard W.

Patent number: 8902056Abstract: A tire pressure monitoring system where the position and orientation of a receiver antenna associated with the tire pressure monitoring system is at a location that is proximate the tire pressure monitoring system. In one embodiment, the receiver antenna is positioned beneath a vehicle chassis. The location of the receiver antenna can be determined by system performance prediction tools that include mean-time-to-warning verses packet error rate curves for a desired packet error rate and packet error rate verses signal-to-noise ratio curves for various operational scenarios and different classes of vehicle that provides a necessary signal-to-noise ratio for a wireless link, and operational scenarios that established desired levels of performance and reliability.Type: GrantFiled: June 14, 2012Date of Patent: December 2, 2014Assignee: GM Global Technology Operations LLCInventors: Vikas Kukshya, Hyok Jae Song, Hui Pin Hsu, Richard W.

Patent number: 8701920Abstract: A fuel cap for a filler neck on a fuel tank includes a cap body having threads for engaging the filler neck when the fuel cap is installed on the filler neck and a cap handle rotatably mounted on the cap body. A clutch acts between the cap handle and the cap body to permit the cap handle to rotate freely on the cap body when the clutch is disengaged. When the clutch is engaged, rotation of the cap handle will rotate the cap body so that the user can remove the fuel cap from the filler neck to refuel the vehicle. A pressure-sensing diaphragm disengages the clutch when the pressure differential between the fuel vapor pressure and the atmospheric pressure exceeds a predetermined threshold and engages the clutch when the pressure differential between the fuel vapor pressure and the atmospheric pressure is less than the predetermined threshold.Type: GrantFiled: August 27, 2011Date of Patent: April 22, 2014Assignee: GM Global Technology Operations LLCInventors: Richard W. Wiese, Jonathan J Stec, Timothy E. McCarthy

Patent number: 8112261Abstract: To facilitate GPS hardware selection and evaluate performance of vehicle integrated GPS hardware, including various types of GPS antennas and receivers, within different vehicle operating environments, embodiments of the invention are used to provide a simulator which does not require physical GPS hardware to simulate GPS system performance. Preferably, the simulator randomly generates one or more GPS system link budget variables, within predetermined performance bounds, in order to predict GPS system performance in a specific vehicle operating environment for a given antenna radiation pattern and/or GPS receiver. The simulator employs a Monte Carlo technique to evaluate the GPS system performance based on generated pools of link budget variables.Type: GrantFiled: March 31, 2008Date of Patent: February 7, 2012Assignee: GM Global Technology Operations, LLC.Inventors: Hyok J.

Patent number: 7994905Abstract: There is provided an exemplary tire pressure monitoring (TPM) system that can use a half-duplex wireless link to communicate between one or more wheel-mounted sensor units and a vehicle-mounted transceiver unit. The half-duplex wireless link enables the sensor units to report sensor readings to the transceiver unit, and it enables the transceiver unit to make configuration changes to the sensor units for improved communication. Some examples of wireless settings that can be modified include modulation settings, data encoding/decoding settings, error correction settings, and transmission power settings.Type: GrantFiled: December 10, 2008Date of Patent: August 9, 2011Assignee: GM Global Technology Operations LLCInventors: Vikas Kukshya, Hyok J.

Patent number: 7382239Abstract: An onboard wireless communication system for a vehicle, such as a tire pressure monitoring system (“TPMS”) is disclosed. The TPMS includes wheel-mounted radio frequency (“RF”) sensor/transmitters that transmit RF signals conveying tire pressure information, at least one RF relay element, and an RF receiver coupled to a TPMS processor. The RF relay element(s) relay the RF signals from the sensor/transmitters to the RF receiver to reduce the negative effect of electromagnetic field scattering caused by conductive parts of the vehicle.Type: GrantFiled: August 23, 2005Date of Patent: June 3, 2008Assignee: GM Global Technology Operations, Inc.Inventors: Hyok J.

Patent number: 5028866Abstract: An electromechanical XY carriage sweeps a magnetic or electrical field probe across a circuit board line by line to acquire field strength data as a function of probe position relative to the board. Colored field maps are produced. The carriage is controllable to obtain very high resolution data. A magnetic probe includes a single loop oriented parallel to the board or a loop oriented perpendicular to the board and selectively parallel to or perpendicular to the x axis of the carriage. Different field maps are produced by different probe orientations and each provides information regarding the circuit traces which carry rf currents.Type: GrantFiled: May 30, 1990Date of Patent: July 2, 1991Assignee: General Motors CorporationInventor: Richard W.
