Patent number: 9296368Abstract: Methods, systems, and vehicles are provided for determining an effective brake pedal position for a vehicle. A determination is made as to whether automatic braking is occurring for a vehicle. If the automatic braking is occurring, a measure of braking is determined for the vehicle. The effective pedal position of the brake pedal is determined to be a position of the brake pedal that would be expected to be required to attain the measure of braking if automatic braking were not occurring.Type: GrantFiled: October 30, 2013Date of Patent: March 29, 2016Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Patrick J. O'Leary, Bret J. Keller, Barbara A. Shuler, Eric E. Krueger

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: 7343897Abstract: An engine control system includes an engine with an output shaft. A power take-off device interfaces with the output shaft and provides rotational power to an auxiliary device. A user input device includes a first engine speed control that commands an increase in engine speed by a first amount to increase the rotational power to the auxiliary device when a user selects the first engine speed control. A second engine speed control commands an increase in engine speed by a second amount that is greater than the first amount to increase the rotational power to the auxiliary device when the user selects the second engine speed control. The user input device includes a speed cancellation control that commands a reversal of a net increase in the speed of the engine that is commanded via the user input device when the user selects the speed cancellation control.Type: GrantFiled: March 22, 2006Date of Patent: March 18, 2008Assignee: GM Global Technology Operations, Inc.Inventors: Kerfegar K.
