Patent number: 8131442Abstract: A method for operating a cruise control system for a vehicle. The method can identify certain low speed environments, like parking lots, where usage of the cruise control system is usually inappropriate and can disable the system accordingly. According to one embodiment, a full speed range adaptive (FSRA) cruise control system compares a steering wheel position to a steering wheel threshold to determine if the vehicle is operating in an inappropriate low speed environment and, if so, disables the cruise control system accordingly.Type: GrantFiled: November 28, 2007Date of Patent: March 6, 2012Assignee: GM Global Technology Operations LLCInventors: Pamela I. Labuhn, Charles A. Green, James N. Nickolaou, Patrick J. O'Leary, Daniel J. Bartz

Patent number: 7719410Abstract: A method and apparatus is provided for detecting and avoiding an obstacle using a system of a vehicle. The method includes the steps of detecting a distance between the obstacle and the vehicle, generating an action when the distance between the obstacle and the vehicle is less than a threshold, determining whether an override of the system has been initiated, and disabling the action if it is determined that the override has been initiated. The system includes an obstacle detector, an action generator, an override mechanism, and a processor configured to implement the steps of the method set forth above.Type: GrantFiled: January 8, 2007Date of Patent: May 18, 2010Assignee: GM Global Technology Operations, Inc.Inventors: Pamela I.

Patent number: 7375620Abstract: A rear obstacle detection and avoidance system for use on a vehicle comprises a rear obstacle detector that is coupled to the vehicle and measures the distance between the vehicle and an obstacle substantially to the vehicle's rear, a speed sensor that determines vehicle speed, an alert generator that notifies an occupant of the vehicle of a rear obstacle, and a processor that is coupled to the rear obstacle detector, the speed sensor, and the alert generator. The processor causes the generation of a first alert when the vehicle's speed is less than a threshold speed and the distance between the vehicle and an obstacle substantially to the vehicle's rear is less than a first distance determined in accordance with a first function of speed vs. distance.Type: GrantFiled: December 8, 2005Date of Patent: May 20, 2008Assignee: GM Global Technology Operations, Inc.Inventors: Uzmaa H.

Patent number: 6871145Abstract: A method for predicting an impact condition between a host vehicle and an object detected in a path of travel of the host vehicle includes receiving measured parameters from the host vehicle and the object, and receiving a system sensitivity input from a driver of the host vehicle. A braking response of the driver of the host vehicle is estimated, based on the received system sensitivity input, and a projected travel range profile for both the host vehicle and the object is determined, based upon the measured parameters and the estimated braking response. The impact condition is established whenever a comparison of the projected travel range profile for the host vehicle and for the object establishes an intersection therebetween.Type: GrantFiled: November 26, 2002Date of Patent: March 22, 2005Assignee: General Motors CorporationInventors: Osman D.

Patent number: 5014200Abstract: An adaptive cruise system for a vehicle maintains a desired selected operator-set speed in the absence of a detected preceding target vehicle and adjusts the vehicle speed when a target vehicle is detected to maintain a following distance that is set by the vehicle operator. An alert distance is computed that is a predetermined function of a distance based on driver reaction time. To provide for the driver selectable trailing distance, the driver reaction term of the alert distance is adjusted by the vehicle operator to achieve a desired distance to the target vehicle.Type: GrantFiled: February 20, 1990Date of Patent: May 7, 1991Assignee: General Motors CorporationInventors: William J.
