Patent number: 7836988Abstract: A method for operating a parallel hybrid drive train of a vehicle having an internal combustion engine, an electric engine and an output. The electric engine being located in the power drive between the output and the internal combustion engine. A second shifting element is located between the internal combustion engine and the electric engine and a first shifting element between the electric engine and the output. Output torque driving the output can be adjusted according to the transmitting capacities of the first and second shifting elements and according to the input torque of the electric engine and/or internal combustion engine. These adjustments are corrected according to standards derived from divergences found in parameters during operation of the drive train.Type: GrantFiled: February 5, 2007Date of Patent: November 23, 2010Assignee: ZF Friedrichshafen AGInventors: Ralf Dreibholz, Johannes Kaltenbach, Michael Gromus, Stefan Blattner, Bernd Allgaier, Stefan Kilian, Peter Schiele, Friedrich Tenbrock, Gerd Frotscher

Patent number: 7762922Abstract: A method is described for operating a parallel hybrid device train (1) of a vehicle having an internal combustion engine (2), an electric engine (3) and an output (5) wherein the electric engine (3) is disposed in the power train between the output (5) and the internal combustion engine (2) and both between the internal combustion engine (2) and the electric engine (3) and between the electric engine (3) and the output (5) is respectively provided a frictionally engaged shifting element (7, 8). In addition, a nominal output torque abutting on the output (5) can be adjusted according to the transmitting capacity of the first shifting element (8) located between the electric engine (3) and the output (5). According to the invention, the transmitting capacity of the first shifting element (8) is adjusted under control according to the nominal input torque required so that the first shifting element (8) has a transmitting capacity needed for producing the nominal output torque on the output (5).Type: GrantFiled: February 5, 2007Date of Patent: July 27, 2010Assignee: ZF Friedrichshafen AGInventors: Ralf Dreibholz, Johannes Kaltenbach, Michael Gromus, Stefan Blattner, Bernd Allgaier, Stefan Kilian, Peter Schiele, Friedrich Tenbrock, Gerd Frotscher

Patent number: 7540823Abstract: New alternatives for integration of electric machines (EM1 to EM6) in an extensively integrated dual-clutch transmission (1) having one dual clutch (2), one first input shaft (8) designed as a hollow shaft and one second input shaft (9) co-axially supported in the first input shaft (8), the same as a first countershaft (10) designed as a hollow shaft and a second countershaft (11) co-axially supported. The possibilities of construction of such dual-clutch transmission are improved, and new areas of use under limiting installation space conditions are disclosed. The efficiency of the same, relative to certain possible uses, is optimized by adequate location of at least one electric machine (EM1 to EM6) and using it for a multiplicity of modes of operation are proposed.Type: GrantFiled: July 26, 2006Date of Patent: June 2, 2009Assignee: ZF Friedrichshafen AGInventors: Stefan Kilian, Rafel Pascual
