Patent number: 8521377Abstract: A system includes a vehicle speed module that determines a speed of a vehicle. An engine control module receives a first target speed signal and a torque request signal from an adaptive cruise control (ACC) module. The ACC module is separate from the engine control module. A first comparison module compares the first target speed signal to the speed of the vehicle to generate a first assessment signal. A first target speed module sets a second target speed signal equal to one of the first target speed signal and a predetermined value based on the first assessment signal. The engine control module controls an engine to provide an engine output torque based on at least one of the torque request signal and the second target speed signal.Type: GrantFiled: May 14, 2012Date of Patent: August 27, 2013Inventors: Patrick J.

Patent number: 8301355Abstract: A cruise control system comprises a passing detection module and a speed regulator module. The passing detection module selectively detects execution of a passing maneuver based on an accelerator pedal position (APP) measured by an APP sensor and actuation of a Set/Coast input to the cruise control system when a vehicle speed is greater than a target speed. The speed regulator module regulates the vehicle speed based on the target speed and updates the target speed to the vehicle speed when the passing maneuver is detected.Type: GrantFiled: May 21, 2009Date of Patent: October 30, 2012Inventors: Patrick J.

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.
