Patent number: 8195456Abstract: A system and method for entering a destination into a navigation system, usually a vehicle navigation system, that uses phonetic letter families, or groups of letters which sound similar, to improve the reliability and accuracy of speech recognition. The method involves grouping each letter of the English alphabet into a family of letters which sound similar, such as A, J, and K. When a destination name is spelled by a user, each letter is recognized in terms of the phonetic letter family to which it belongs. This phonetic equivalent spelling is compared to the navigation database of street, city, and state names, which has also been converted to its phonetic equivalent spelling. If a match is found, the user is asked to confirm that this is the desired destination.Type: GrantFiled: December 4, 2009Date of Patent: June 5, 2012Assignee: GM Global Technology Operations LLCInventors: Robert P. Roesser, Sarmad Y. Hermiz

Patent number: 8081210Abstract: A system and method for mitigating the effects of Doppler shift, multipath and/or noise for a mobile receiver, such as on a vehicle, that is receiving broadcast television signals. The vehicle may include a map database and a GPS receiver that combine to identify the location of the vehicle on the roadway. The receiver on the vehicle includes a rotatable antenna that can be either mechanically or electronically directed towards a broadcast tower that is broadcasting the signal that the vehicle wishes to receive. Therefore, multipath effects and other noise conditions can be mitigated or eliminated by more precisely directing the antenna towards the source of a signal. Further, the receiver on the vehicle can use the forward velocity of the vehicle and the direction of the broadcasting tower to determine the movement of the vehicle relative to the tower to correct for the Doppler shift.Type: GrantFiled: October 31, 2008Date of Patent: December 20, 2011Assignee: GM Global Technology Operations LLCInventor: Robert P.

Patent number: 8036785Abstract: A method for controlling a powertrain of a hybrid vehicle having an engine, a motor/generator, a battery that is rechargeable using at least one of the engine and the motor/generator, and a powertrain control module (PCM) includes determining a current location of the vehicle as a starting point of a preferred route, recording a user-selected ending point of the preferred route, and processing route information using the PCM to thereby determine an optimally fuel efficient route for reaching the ending point. The method includes automatically executing the powertrain control strategy over the optimally fuel efficient route by substantially depleting a charge level of the battery as the vehicle travels over the optimally fuel efficient route such that the charge level of the battery is depleted when the vehicle reaches the ending point. When the ending point is not recorded, the PCM can default to a charge-sustaining mode.Type: GrantFiled: March 23, 2009Date of Patent: October 11, 2011Assignee: GM Global Technology Operations LLCInventors: Joel M.

Patent number: 7356407Abstract: The invention includes cohort analysis as an element of an in-vehicle navigation system. As an operator makes trips from an origin to a destination, the navigation system records various route segments chosen. These choices are compared to route segments comprising a minimal time route calculated for the trip. Segments not part of the prescribed route are collected and periodically sent along with the origin and destination to a centralized server, wherein they are stored in a database. The central server also has an extensive map database that lists many attributes for each segment not generally included in an in-vehicle database. The attributes include variables pertaining to traffic flow, e.g. speed, number of lanes, lane width; topology, e.g. possible turns at endpoints; geometry, e.g. horizontal shape, vertical curvature, and super-elevation; usage, e.g. freeway, arterial, local, residential, business; and topography, e.g. buildings, trees, open-space, facilities, and stores.Type: GrantFiled: October 6, 2005Date of Patent: April 8, 2008Assignee: GM Global Technology Operations, Inc.Inventors: Richard A.
