Patent number: 8798841Abstract: A system and method designed to improve sensor visibility for a host vehicle operating in an autonomous driving mode when one or more forward-looking sensors are being occluded or obstructed. According to an exemplary embodiment, when a forward-looking object detection sensor is being obstructed by a target vehicle located closely ahead of the host vehicle, the method determines if lateral movement by the host vehicle within its own lane is appropriate to improve sensor visibility around the target vehicle. If lateral movement is deemed appropriate, the method generates lateral movement commands that dictate the direction and distance of the lateral movement by the host vehicle. This may enable the object detection sensors to at least partially see around the obstructing target vehicle and improve the preview distance of the sensors.Type: GrantFiled: March 14, 2013Date of Patent: August 5, 2014Assignee: GM Global Technology Operations LLCInventors: James N. Nickolaou, Joel Pazhayampallil, Michael P. Turski

Publication number: 20130231837Abstract: A method for regulating an electronic limited slip differential (eLSD) to apportion generated drive torque between first and second road wheels includes determining maximum torque capability of each wheel to identify more and less capable wheels. The method also includes determining a remaining portion of the drive torque by subtracting the maximum torque capability of the less capable wheel from the generated torque. The method additionally includes transferring to the more capable wheel a portion of the drive torque that is equal to the torque capability of the more capable wheel if the remaining portion is greater than the torque capability of the more capable wheel. Furthermore, the method includes transferring to the more capable wheel the remaining portion of the drive torque if the remaining portion is equal to or less than the torque capability of the more capable wheel. A vehicle employing the method is also disclosed.Type: ApplicationFiled: March 2, 2012Publication date: September 5, 2013Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: James H.

Patent number: 8403812Abstract: An exemplary engine control system and method for controlling a vehicle engine during certain shifting maneuvers that involve a manual transmission, such as a ‘no-lift upshift’ where the driver does not release the accelerator pedal during manual shifting. The engine control method may be used to temporarily control the vehicle engine during a no-lift upshift maneuver so that the engine performs well without reaching excessively high engine speeds that could result in vehicle instability or damage. The engine control method described herein may be used with other performance driving maneuvers and techniques as well, such as a power shift maneuvers, etc.Type: GrantFiled: January 30, 2009Date of Patent: March 26, 2013Assignee: GM Global Technology Operations LLCInventors: Michael P.

Patent number: 8290666Abstract: A system and method for controlling a vehicle engine during one or more performance driving events, such as a performance takeoff, shifting or cornering event. The engine control system may be used to maintain stability when the vehicle is being driven in a competitive or aggressive fashion by temporarily controlling the vehicle engine through the manipulation of engine torque, engine speed or some other means. If the engine control system receives competing command signals from different vehicle subsystems, then the system may arbitrate or otherwise manage the competing command signals so that different subsystems can function together properly. In one embodiment, the engine control system blends the commands signals from two or more subsystems.Type: GrantFiled: February 23, 2009Date of Patent: October 16, 2012Assignee: GM Global Technology Operations LLCInventors: Michael P.

Patent number: 8200408Abstract: A method for active traction control of a vehicle can be performed to optimize corner exiting performance of a vehicle that is operating in a high performance or racing environment. The method estimates a real-time tire traction value during operation of the vehicle, computes a remaining tire traction value based upon a comparison of the estimated real-time tire traction value to a total available tire traction value, and calculates a traction system torque limit from the remaining tire traction value. The calculated torque limit can then be used to limit the actual traction system torque of the vehicle as needed in a real-time manner.Type: GrantFiled: December 22, 2008Date of Patent: June 12, 2012Assignee: GM Global Technology Operations LLCInventors: Michael P.

Patent number: 8175785Abstract: A system and related operating method for performance launch control of a vehicle begins by receiving a user-selected driving condition setting that is indicative of road conditions. The method also collects real-time vehicle status data during operation of the vehicle, and derives a target wheel slip profile from the user-selected driving condition setting and the real-time vehicle status data. The actual propulsion system torque of the vehicle is limited using the target wheel slip profile, resulting in improved performance for standstill launches.Type: GrantFiled: December 22, 2008Date of Patent: May 8, 2012Assignee: GM Global Technology Operations LLCInventors: Michael P.

Patent number: 7617036Abstract: A method and system, according to one embodiment of the present invention, provide a means to accurately determine the velocity of a vehicle. An initial estimation of the velocity of the vehicle is calculated based on rates of rotation of a plurality of wheels on the vehicles. If any of the wheels on the vehicle are in a brake control, or traction control, situation, the initial estimation is modified based on an acceleration of the vehicle to generate a modified estimation of the velocity of the vehicle.Type: GrantFiled: September 20, 2006Date of Patent: November 10, 2009Assignee: GM Global Technology Operations, Inc.Inventors: Hualin Tan, Edmund S.

Patent number: 7549108Abstract: Systems, methods and data structures are provided for representing robust data transmitted within a control system. The data structure includes at least two data fields identifying sub-modules and sub-modes of the control system, and optionally includes a third field for designating a primary operating mode of the control system and/or a fourth field representing a handshaking bit or value. The operating modes, sub-modes and sub-module designators are represented by values of the bits selected such that no single bit transition results in the selection of another valid operating state of the control system. As a result, single bit errors will not produce erroneous operating results. Similar concepts can be optionally applied to ensure that errors in contiguous sets of four, eight or any other number of bits do not produce valid states represented by the data structure.Type: GrantFiled: July 27, 2005Date of Patent: June 16, 2009Assignee: GM Global Technology Operations, Inc.Inventors: Kerfegar K.
