Publication number: 20070208467Abstract: A method is provided for controlling a hybrid vehicle powertrain, including recording a starting and ending point of a desired route, determining an optimally fuel efficient route, and executing a powertrain control strategy based on the route. Real-time traffic data and topographical data are continuously evaluated, and the route and powertrain control strategy are updated based on the data. A hybrid vehicle is also provided having an engine, a motor/generator, a battery, and a navigation system for receiving a route starting point and ending point. A powertrain control module (PCM) detects the battery charge and determines a powertrain strategy along an optimally fuel efficient route based on the detected charge level when the points are selected, and sustains the charge level in the absence of user-selected route points. Sensors receive real-time traffic data, and the navigation system includes topographical data for determining the optimally fuel efficient route.Type: ApplicationFiled: March 5, 2007Publication date: September 6, 2007Applicant: GM Global Technology Operations, Inc.Inventors: Joel Maguire, Madhusudan Raghavan, Robert Roesser

Publication number: 20070184933Abstract: A transmission is provided that utilizes a unique packaging scheme for torque-transmitting mechanisms and gear drive members in order to minimize the overall axial length of the transmission. Specifically, the transmission may include a clutch housing that is connected for common rotation with a transmission input member. A rotatable hub member may be connected for common rotation with both the clutch housing and a gear member, thereby connecting the gear member for common rotation with the input member. Preferably, the rotatable hub member is connected to the clutch housing by the reaction plates that extend from the clutch housing. First and second torque-transmitting mechanisms may be packaged within the clutch housing.Type: ApplicationFiled: February 3, 2006Publication date: August 9, 2007Inventors: Joel Maguire, Madhusudan Raghavan

Publication number: 20070125184Abstract: An easily packaged torque monitoring system accurately captures driveline torque data for use by engine, transmission or other vehicle controllers. The torque monitoring system utilizes a structural member to hydraulically connect a driving member with a driven member. A pressure-sensing device is operatively connected with a fluid chamber in the structural member through which the driving member drives the driven member. The pressure-sensing device senses a pressure level within the chamber. The amount of torque transmitted from the driving member to the driven member is directly linearly related to the sensed pressure. In one embodiment, the pressure-sensing device is a surface acoustic wave sensor in contact with the hydraulic fluid that wirelessly relays a sensor signal (i.e., a signal with a value corresponding with sensed pressure and thus with torque) to a controller.Type: ApplicationFiled: December 2, 2005Publication date: June 7, 2007Inventors: Joel Maguire, John Maten

Publication number: 20070099758Abstract: The present invention provides a method for controlling a selectable one-way clutch, or SOWC, such that engine braking is enabled. Additionally, the method of the present invention is adapted to provide engine braking using the SOWC such that a separate clutch is not required. The method is initiated by identifying a downshift command. After the downshift command has been identified, the off-going clutch associated with the current speed ratio is released. Engine speed is preferably increased to bring the relative speed across a selectable one-way clutch to approximately zero. Thereafter, the selectable one-way clutch is engaged such that is capable of holding torque in both directions. As the selectable one-way clutch can hold torque in both directions, torque is transmittable from the transmission to the engine and engine braking is thereby enabled.Type: ApplicationFiled: October 31, 2005Publication date: May 3, 2007Inventors: Joel Maguire, Scott Wittkopp
