Publication number: 20240042871Abstract: A method for increasing the power during an acceleration process of an electrically operated motor vehicle with at least one electrical machine includes detecting a storage request by at least one control unit and initiating an increase in the rotation speed of a rotor of the electrical machine of the motor by the control unit before an acceleration request, so that kinetic energy is stored in the rotor of the electrical machine. The acceleration request is detected by the control unit and the energy stored in the rotor of the electrical machine is released during the acceleration process.Type: ApplicationFiled: December 2, 2021Publication date: February 8, 2024Inventors: Stefan Wurm, Thomas Traidl, Simon Kaimer

Publication number: 20230271600Abstract: A method is provided for operating a drive train comprising an internal combustion engine or an electric machine as a primary drive and an electric machine as a secondary drive, wherein the electric machine is detachably coupled, together with an inverter and controller, on one of the vehicle axles. The electric machine and at least one switchable element is actuated in order to minimize drag losses of the electric machine and to provide a defined connection time for the electric machine. The electric machine is stationary and decoupled during a first speed range. The electric machine is actuated at a preset speed during a second speed range, where a defined connection time is not possible if the electric machine were stationary. The electric machine is coupled to the axle and rotates at the vehicle speed in the third range, when losses while coupled are lower than if uncoupled.Type: ApplicationFiled: June 9, 2021Publication date: August 31, 2023Inventors: Stefan Laimgruber, Johannes Fuchs, Daniel Lindvai-Soos, Markus Thier, Simon Kaimer

Patent number: 8930096Abstract: The invention relates to a method for lubricating a transmission of a motor vehicle, particularly a power divider, wherein the oil is conveyed by an oil pump from an oil sump to components of the transmission. The amount of oil conveyed is set as a function of the predetermined parameters. The conveyed amount of oil is controlled in that the oil pump is operated intermittently, e.g. is switched on and off repeatedly. The invention further describes a device for carrying out the method.Type: GrantFiled: June 23, 2009Date of Patent: January 6, 2015Assignee: Magna Powertrain AG & Co KGInventors: Simon Kaimer, Martin Parigger, Franz Gratzer

Patent number: 8151965Abstract: A clutch arrangement having an input element and an output element that are rotatable relevant to one another, a friction clutch and a pump. The friction clutch couples the input element with the output element in dependence on a hydraulic pressure in a pressure space of the clutch arrangement. The pump has a first pump part that is rotationally fixedly connected to the input element and a second pump part that is rotationally fixedly connected to the output element. The pump may be driven by a rotary movement of the input element and the output element relative to one another, with a pressure side of the pump being connected to the pressure space. An orifice having a substantially temperature independent leakage characteristic is arranged in a leakage line that leads from the pressure space to a low pressure space and which extends parallel to the pump.Type: GrantFiled: August 12, 2008Date of Patent: April 10, 2012Assignee: MAGNA Powertrain AG & Co KGInventors: Thomas Linortner, Martin Parigger, Simon Kaimer, Franz Gratzer

Patent number: 7949453Abstract: A method controlling a clutch arrangement that serves, in a powertrain of a motor vehicle, for the transmission of a torque from an input element to an output element. Starting from an activated state of the clutch arrangement, a respective estimated torque value is calculated in repeating calculation cycles. A torque build-up value is calculated in dependence on at least one speed difference value. A torque reduction value is calculated in dependence on at least the last calculated estimated torque value. The estimated torque value is re-calculated on the basis of the last calculated estimated torque value by up integration of the calculated torque build-up value and down integration of the calculated torque reduction value. The recalculated estimated torque value is compared with a torque threshold value. The clutch arrangement is deactivated when the recalculated estimated torque value is below the torque threshold value.Type: GrantFiled: August 12, 2008Date of Patent: May 24, 2011Assignee: MAGNA Powertrain AG & Co KGInventors: Martin Parigger, Thomas Linortner, Simon Kaimer, Heribert Dietrich
