Patent number: 8725339Abstract: A method for controlling a hybrid traction assembly includes an initial depleting phase which begins at the beginning of the vehicle mission and where the hybrid traction assembly is controlled to cause depletion of the storage device at a high first mean depletion rate, at least one sustaining phase where the hybrid traction assembly is controlled so that the state of charge is maintained in a predetermined sustaining range. The method further includes a second depleting phase which extends between the initial depleting phase and the sustaining phase, wherein the hybrid traction assembly is controlled to cause depletion of the storage device at a second mean depletion rate, the second mean depletion rate being lower than the first mean depletion rate.Type: GrantFiled: December 22, 2010Date of Patent: May 13, 2014Assignee: Renault TrucksInventors: Thomas Justin, Michael Millet

Patent number: 8712676Abstract: Probe data is analyzed to derive Longitudinal Speed Profiles (LSPs) and an Optimal Longitudinal Speed Profile (18) for each road segment or link in a digital map network. The Longitudinal Speed Profiles (LSPs) profiles are calculated during defined time spans whereas the Optimal Longitudinal Speed Profile (18) is based on the LSP for the time span corresponding only to free flow traffic conditions. All of the LSPs can used to create a respective energy cost for each time span, or only the OLSP (18) can be used (or alternatively the RRDSL 16 or LRRDSL 17) to calculate an energy cost for the free flow conditions only. The energy cost can be used to predict the energy required by a vehicle to traverse the link. Navigation software can use the energy cost to plan the most energy efficient route between two locations in the digital map. Sensory signals can be activated if a driver strays from the Optimal Longitudinal Speed Profile (18) to achieve extremely high levels of energy efficiency.Type: GrantFiled: September 14, 2012Date of Patent: April 29, 2014Assignee: TomTom Global Content B.V.Inventors: Volker Hiestermann, Robert Joannes Van Essen, Edwin Bastiaensen, Stephen T'Siobbel

Patent number: 8700284Abstract: A towed vehicle is towed by a towing vehicle. The towed vehicle includes a motor/generator for both regenerative braking and for powering wheels. A tow member connects the towed vehicle to the towed vehicle. A sensor measures or infers the tension and compression in the tow member. A computer communicates with the sensor and with the motor/generator. The computer commands the motor/generator to either utilize regenerative braking or provide assistance in propulsion of the towed vehicle based upon the tension and compression forces in the tow member.Type: GrantFiled: May 15, 2012Date of Patent: April 15, 2014Assignee: Ford Global Technologies, LLCInventors: Scott Wojtkowicz, Joseph Norman Ulrey, Ross Dykstra Pursifull

Publication number: 20140081491Abstract: A vehicle includes a torque generating device, a transmission, and a controller. The transmission has one or more clutches. The controller executes a method, which includes measuring an amount of slip across an identified offgoing clutches and determining whether the offgoing clutches have slipped prior to a modeled clutch torque capacity reaching zero. A status is assigned indicating that the offgoing clutches are released if the offgoing clutch has slipped prior to the modeled clutch capacity reaching zero. The controller induces slip across the identified offgoing clutches to a calibrated low, non-zero level after recording the value, including by enforcing the low, non-zero slip value using one or more acceleration profiles.Type: ApplicationFiled: September 14, 2012Publication date: March 20, 2014Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Pinaki Gupta, Lawrence A.

Patent number: 8676452Abstract: A hybrid-type working machine 1 includes an engine 11; a supercharger 42; an electric generator 12 that performs electricity generation by the driving force of the engine 11 and assists the driving force of the engine 11 through its own driving force; an inverter circuit 18A that is connected to an electric terminal of the electric generator 12; and a controller 30 which includes a nonvolatile memory 31 that stores first information indicating a correlation between the revolutions of the engine 11, the boost pressure of the supercharger 42 and an output upper limit value of the engine 11, and drives the inverter circuit 18A. The controller 30 controls the inverter circuit 18A so that the electric generator 12 assists the driving force when the required output exceeds the output upper limit value, based on a correlation stored in the nonvolatile memory 31.Type: GrantFiled: March 31, 2010Date of Patent: March 18, 2014Assignee: Sumitomo Heavy Industries, Ltd.Inventors: Koji Kawashima, Makoto Yanagisawa
