Patent number: 11780421Abstract: A method for controlling an electric drive unit (EDU) having a motor-driven torque converter includes receiving a request signal indicative of a requested output torque of the EDU, and operating the motor at a target motor speed using the requested output torque. The target motor speed minimizes system losses while achieving the requested output torque. When the requested output torque remains below a calibrated threshold and a turbine speed is less than a corner speed of the motor, a torque converter clutch (TCC) transitions to or remains in a locked state. The controller commands the TCC to transition to an unlocked state to reach the target motor speed, thereby selectively enabling torque multiplication. A powertrain system includes a driven load and the EDU. A computer readable storage medium may include executable instructions for performing the method.Type: GrantFiled: December 27, 2021Date of Patent: October 10, 2023Assignee: GM Global Technology Operations LLCInventors: Norman K.

Patent number: 11724594Abstract: Engine controllers and control schemes that facilitate skip fire engine operation in conjunction with use power take-off devices are described. In one aspect, a skip fire mode is exited when the power take-off unit is engaged and the current torque request exceeds a torque threshold. In some embodiments, the exit is delayed when the temperature of an after treatment system is below a designated temperature threshold. In another aspect, the engine transitions to the skip fire mode when the power take-off unit disengages. In some embodiments, exiting is conditioned on the current torque request being less than a torque threshold. In some embodiments, the transition is made immediately, whereas in others the transition only occurs when the power take-off unit is not reengaged for a period of time or is further conditioned on determining that the power take-off unit is likely to remain disengaged for the period of time.Type: GrantFiled: July 10, 2020Date of Patent: August 15, 2023Assignees: Tula Technology, Inc., Cummins Inc.Inventors: J.

Patent number: 8763734Abstract: A drive through crankshaft assembly which selectively provides rotational power to a vehicle accessory while continuously providing rotational power to a second vehicle accessory. Rotational power is selectively provided using a cone clutch assembly that is modular. The cone clutch assembly provides power to the first vehicle accessory when it is in an engaged state. The first vehicle accessory is turned off by putting the cone clutch assembly into a disengaged state using a clutch control system.Type: GrantFiled: April 5, 2007Date of Patent: July 1, 2014Assignee: Haldex Brake CorporationInventors: Travis L. Fetter, Michael R. Jenkins

Patent number: 8739905Abstract: A drive apparatus driven by a prime mover that has a prime mover output shaft is disclosed. The drive apparatus has a housing and a power take off. The power take off is driven by the prime mover output shaft and selectively drives a power take off output shaft. The drive apparatus further has a variable speed transmission disposed within the housing. The variable speed transmission drives a transmission output shaft, which in turn drives a first clutch mechanism and a second clutch mechanism. A first drive axle is engaged to and selectively driven by the first clutch mechanism and a second drive axle is engaged to and selectively driven by the second clutch mechanism.Type: GrantFiled: August 10, 2010Date of Patent: June 3, 2014Assignee: Hydro-Gear Limited PartnershipInventor: Michael L. Bennett

Publication number: 20140076643Abstract: An extendable frame work vehicle offering enhanced versatility, safety and effectiveness. The vehicle includes an adjustable frame with front and rear portions that extend or retract with respect to each other. The front portion is supported by a first pair of wheels and said rear portion is supported by a second pair of wheels. Each wheel is independently driven and steered. The vehicle also includes an engine mounted on the rear portion of the frame. Incorporated into the vehicle is an electro-hydraulic assembly which enables extension and retraction of the adjustable frame. The assembly includes a sensor-responsive microprocessor controller, at least one hydraulic pump, at least one hydraulic drive motor, and at least one valve network.Type: ApplicationFiled: November 25, 2013Publication date: March 20, 2014Applicant: EXTENDQUIP, LLCInventors: Chris Osswald, Walter A. Osswald, Marcus F. Dack, Kenneth Buelt, Thomas E. Price, JR., Alan Severns, Jeffrey A. Wierschke, Joe A. Racz, David R. Bauer, Justin D. Gasal

Patent number: 8666621Abstract: A PTO control system for allowing selection between an independent PTO mode and an interlock PTO mode, comprising a mode-switch command input device 11 for giving an instruction on selection between the independent PTO mode and the interlock PTO mode, a PTO setting device 12 having an engaging position for producing an engaging command and a disengaging position for producing a disengaging command of the PTO clutch, and a PTO control unit for controlling a PTO clutch in response to a pedal operational position of a brake pedal, a mode selected by the mode-switch command input device, and a position selected by the PTO setting device. PTO mode switch implementation processing is suspended when the PTO transmission system is in a power transmittable state, while the PTO mode switch implementation processing is permitted when the PTO transmission system is in the power non-transmittable state.Type: GrantFiled: March 16, 2010Date of Patent: March 4, 2014Assignee: Kubota CorporationInventors: Yushi Matsuzaki, Susumu Umemoto, Akira Hiwatashi, Shota Nagasawa, Suguru Kagawa

Patent number: 8616310Abstract: The instant invention is an electric machine/tractor particularly intended for farming, gardening and landscaping and is nonpolluting and self charging. The tractor accommodates standard farm implements and can supply electrical power to remote areas. To achieve these goals, the machine is comprised of a frame and wheels which are driven independently by hydraulic motors powered by a variable volume, hydrostatic pump that is driven in line, by an electric motor that also drives a hydraulic lift pump and a power-take-off shaft through belts. The hydrostatic pump is controlled by the operator for forward and reverse motion. The electric motor is powered by batteries and the batteries can be recharged by an on-board photoelectric panel. A combination charger/inverter is located aboard the tractor to charge the batteries from any 110V A.C. power outlet or generate 110V A.C. electrical power from the tractor.Type: GrantFiled: January 14, 2011Date of Patent: December 31, 2013Inventor: Gilbert Thomas Lopez

Patent number: 8606453Abstract: Messaging in a controller area network is modified to hide thermal engine torque and angular velocity change requests originating with selected nodes with relatively low contention access priority from an engine controller and to route the messages instead through an intermediary controller which is an independent source of thermal engine torque and angular velocity change requests. More specifically, in a hybrid vehicle having a body controller with operational control over power take off equipment, a hybrid controller and a thermal engine controller, angular velocity and torque change requests to support power take off operation are embedded in auxiliary input/output messages. The hybrid controller operates on these auxiliary messages, conflating the embedded angular velocity and torque change requests with its own and rebroadcast in conventional form.Type: GrantFiled: March 8, 2010Date of Patent: December 10, 2013Assignee: International Truck Intellectual Property Company, LLCInventor: Jay E Bissontz
