20120316741 | CONTROL SYSTEM AND METHOD FOR TRANSMISSION CLUTCH CONTROL - A control system for a transmission includes an actuator module, a timer module, and a pulse module. The actuator module engages N hydraulic clutches and disengages M hydraulic clutches to operate the transmission in a gear ratio, wherein N and M are integers greater than zero. The timer module determines a first period starting when the transmission begins operating in the gear ratio. The pulse module selectively supplies a pressure pulse to P of the M hydraulic clutches based on the first period, wherein P is an integer greater than zero. A method for controlling a transmission is also provided. | 12-13-2012 |
20130045835 | METHOD FOR CRANKSHAFT TORQUE MODIFICATION DURING TRANSMISSION SHIFTS USING MULTIPLE TORQUE ACTUATORS AND CONTROL SYSTEM FOR SAME - A method of controlling engine crankshaft torque on a vehicle requests crankshaft torque modification using multiple types of torque actuators prior to and during a single commanded shift, such as an upshift. Appropriate levels of torque modification for the request, as well as appropriate times to make determinations regarding actuator type and make crankshaft torque reduction requests are determined in light of timing of key events during the shift. | 02-21-2013 |
