Filed:

Aug 15, 2007

Appl. No.:

11/839039

Inventors:

Roger A. Clark - Clarkston MI, US

Assignee:

GM Global Technology Operations, Inc. - Detroit MI

International Classification:

F02B 33/44
F02B 33/00
F01L 1/34

US Classification:

60608, 60607, 60609, 1235593, 123 9017

Abstract:

A powertrain includes an Atkinson cycle engine having at least one cylinder, a crankshaft, and an air intake system that provides selective fluid communication between the at least one cylinder and the atmosphere. A motor is in hybrid combination with the engine, and a compressor is configured to selectively pressurize air in the air intake system. The powertrain provides the fuel efficiency of an Atkinson cycle engine while compensating for the reduced torque output of an Atkinson cycle engine.

International Classification:

B60H 1/00

US Classification:

701 36, 701400, 701408, 701465, 701468, 62132, 62133

Abstract:

A method of increasing a range of a vehicle by decreasing trapped HVAC energy at an end of a trip. The method may include the steps of: determining a destination list based on locations where the vehicle may be parked in the future, the destination list accessible by a control module in the vehicle; determining HVAC reduction regions around each of the locations on the destination list, the HVAC reduction regions accessible by the control module; operating a HVAC system while the vehicle is moving; tracking the location of the vehicle relative to the locations on the destination list; and the control module automatically reducing the energy usage of the HVAC system when the vehicle enters one of the HVAC reduction regions.

International Classification:

B62D 53/04

US Classification:

180 142, 701 96

Abstract:

A semi-autonomous vehicle couplable to a parent vehicle is described, and includes a chassis supported on first and second axles coupled to a plurality of wheels, a propulsion system configured to transfer torque to one of the wheels, a steering system configured to control direction of travel of the semi-autonomous vehicle, a braking system configured to apply braking force to the wheels, a high-voltage electrical energy storage system, an extra-vehicle communications system, and an extra-vehicle sensory system. A control system operatively couples to the propulsion system, the steering system, and the braking system. A coupling device is configured to electrically couple the semi-autonomous vehicle to the parent vehicle, the coupling device consisting essentially of a high-voltage DC electrical power bus electrically coupled to the high-voltage electrical energy storage system.

International Classification:

B60L 3/00
G06F 19/00

US Classification:

701 22, 701123

Abstract:

Data collection and analysis processes include collecting energy consumption data from an in-vehicle energy source sensor, collecting emissions data from an in-vehicle emissions sensor, the emissions data reflecting emissions produced by a vehicle, and collecting mileage data from a mileage sensor in the vehicle. The data collection and analysis processes also include processing the energy consumption data and the emissions data as a function of the mileage data, calculating an efficiency rating from the processing, and transmitting results of the processing to a data collection system.

Assignee:

General Motors Corporation - Detroit MI

International Classification:

F02D 1110
F02D 4104

US Classification:

123350

Abstract:

An adaptive electronic throttle control system for internal combustion engine intake air rate control selectively adapts the responsiveness of the intake air rate control to maintain synchronism with other engine control systems including fuel control and dilution control systems according to the responsiveness of such other control systems and, as indicated by current engine operating conditions, according to the need to maintain synchronism to minimize emissions and maximize performance and stability.

Abstract:

The present invention is a technique for operator entry of a time program into a programmable device. An operator adjustable input device having associated time indicia is employed to enter a time signal indicative of a time a selected time. A manual control state input device enables selection of one a control state. When the programmable device is in a program mode the selected control state is stored in a program memory at a location corresponding to the selected time. This program memory stores a program of control states for particular times. When in a control mode a clock signal indicative of the current time permits recall of the control state for the current time, thus permitting control in accordance with the recalled control state. In accordance with the preferred embodiment the programmable device is an electronic thermostat. The operator adjustable input device enables input of the times for storage of temperature offsets in the program mode and enables input of a set point temperature in the control mode.
