Patent number: 10059167Abstract: A method and system for controlling a climate characteristic in a vehicle cabin are provided that control the climate characteristic based, in part, on the location of the vehicle. In one embodiment, the method includes comparing a current location for the vehicle to a predetermined location for the vehicle and comparing a current date and current time to a predetermined date and predetermined time. The method further includes transmitting a climate control signal from a control module to a first subsystem of the vehicle if the current location meets a predetermined location condition relative to the predetermined location and the current date and current time meet predetermined date and time conditions relative to the predetermined date and predetermined time. The climate control signal is configured to cause the first subsystem to change a value of the climate characteristic.Type: GrantFiled: May 28, 2015Date of Patent: August 28, 2018Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventor: Alexander K. Rustoni

Patent number: 8972132Abstract: A method of controlling a transmission includes detecting an occurrence of a downshift in the transmission from a first gear ratio to a second gear ratio. A determination is made whether the vehicle is operating within a freeway speed range, and whether an accelerator pedal is depressed at least a minimum percentage of a fully depressed position. When the downshift from the high gear ratio to the low gear ratio is detected, the vehicle is operating within the freeway speed range, and the accelerator pedal is depressed at least the minimum percentage of the fully depressed position, a countdown timer is started to count down from a pre-defined time to zero. An upshift of the transmission from the second gear ratio to the first gear ratio is restricted while the countdown timer defines a time that is greater than zero.Type: GrantFiled: May 24, 2013Date of Patent: March 3, 2015Assignee: GM Global Technology Operations LLCInventors: Eric Piper, Alexander K. Rustoni, John Janczak, Samantha Victoria Lado

A determination is made whether the vehicle is operating within a freeway speed range, and whether an accelerator pedal is depressed at least a minimum percentage of a fully depressed position. When the downshift from the high gear ratio to the low gear ratio is detected, the vehicle is operating within the freeway speed range, and the accelerator pedal is depressed at least the minimum percentage of the fully depressed position, a countdown timer is started to count down from a pre-defined time to zero. An upshift of the transmission from the second gear ratio to the first gear ratio is restricted while the countdown timer defines a time that is greater than zero.Type: ApplicationFiled: May 24, 2013Publication date: November 27, 2014Applicant: GM Global Technology Operations LLCInventors: Eric Piper, Alexander K.

Patent number: 8893483Abstract: A multi-mode powertrain system employing a power-split configuration to transfer torque to a driveline includes an internal combustion engine fluidly coupled to an exhaust aftertreatment system having a catalytic device. A method for controlling the multi-mode powertrain system includes identifying permitted transition paths between a plurality of engine states. The plurality of engine states includes a default state, a pre-light-off state, a light-off state, and a post-light-off state. A preferred one of the plurality of engine states is selected in response to an output torque request and an operating temperature of the catalytic device. Engine operation is transitioned to the preferred one of the plurality of engine states via the permitted transition paths, and the engine is operated in the preferred one of the plurality of engine states.Type: GrantFiled: August 6, 2012Date of Patent: November 25, 2014Assignee: GM Global Technology Operations LLCInventors: Anthony H. Heap, Kee Yong Kim, Yaoyao Wei, Alexander K. Rustoni

Patent number: 8676417Abstract: A method for managing a threshold increase in output torque capability in a vehicle includes detecting the threshold increase in output torque capability using a controller, and automatically limiting, via the controller, a rate of change of an actual output torque from a transmission of the vehicle in response to the threshold increase. The actual output torque is provided via a traction motor solely using battery power from an energy storage system. The method may include calculating a difference between the threshold increase and the actual output torque, and limiting the rate of change using a rate that is proportional to the difference. A vehicle includes the ESS, a transmission, and a controller. An output member of the transmission is powered using electrical energy from the ESS. The controller manages an increase in output torque capability as noted above.Type: GrantFiled: February 17, 2011Date of Patent: March 18, 2014Assignee: GM Global Technology Operations LLCInventors: Michael Arnett, Alexander K. Rustoni, Sean W. McGrogan, Goro Tamai

Patent number: 8634994Abstract: Methods and systems are provided for vehicle control during braking for vehicles having a transmission gear movable between at least a drive position and a neutral position. A wheel speed sensor measures a wheel speed of the wheel. A controller is coupled to the wheel speed sensor. The controller calculates a parameter using the wheel speed, and shifts the transmission gear from the drive position to the neutral position if the parameter exceeds a predetermined threshold. The parameter is indicative of a load on a component of the vehicle.Type: GrantFiled: August 20, 2010Date of Patent: January 21, 2014Assignee: GM Global Technology Operations LLCInventors: Patrick J.

Patent number: 8494702Abstract: A method for controlling driveline stability in a vehicle includes generating an activation signal indicative of a predetermined vehicle maneuver, which may include a hard braking maneuver on a low coefficient of friction surface. A quick automatic shift to a neutral gear state is executed with a rapid dumping or bleeding off of clutch pressure in a designated output clutch of the vehicle. An activated state of an antilock braking system (ABS) may be used as part of the activation signal. The shift to the neutral gear state may occur only when a current transmission operating state is associated with the high level of driveline inertia. A vehicle includes a transmission and a control system configured to execute the above method.Type: GrantFiled: February 10, 2011Date of Patent: July 23, 2013Assignee: GM Global Technology Operations LLCInventors: Jy-Jen F.
