Patent number: 6234122Abstract: In the case of known electromagnetic actuators each with at least one electromagnet acting on an armature, operational fluctuations of system parameters can lead to incorrect functioning, in particular to increased wear of the actuator, undesired noise generation, and excessive power consumption. In the new method, which is preferably used for operating gas change valves in internal combustion engines, the impact velocity of the armature on the electromagnet is automatically adjusted to a preset value. For this purpose, a controlled variable that depends on a change of inductance of the electromagnet is created as a measure of the impact velocity of the armature on The electromagnet and the controlled variable is adjusted by controlling the energy supply To the electromagnet to provide a setpoint value that the controlled variable adopts at a preset value of the impact velocity of the armature on the electromagnet. This permits reliable continuous duty with the new method.Type: GrantFiled: November 16, 1999Date of Patent: May 22, 2001Assignee: DaimlerChrysler AGInventors: Frank Kirschbaum, Kurt Maute, Madhukar Pandit, Michael Virnich

Patent number: 6119654Abstract: The invention relates to a method for adjusting the drive performance of a motor vehicle having an internal combustion engine with spark ignition. A set torque is determined on the basis of a desired torque which is input by the driver, and possibly additional desired torque requirements. The desired torque is achieved by influencing the load and/or the ignition angle. For this purpose, the invention distinguishes between three operating states. In a first operating state, the torque is adjusted with optimum efficiency by load regulation; in a second operating state the torque adjustment is made as rapidly as possible by an additional ignition angle adjustment. Finally, in the third operating state the torque specification for load regulation is established and the remaining torque adjustment is made by an additional ignition angle adjustment.Type: GrantFiled: February 22, 1999Date of Patent: September 19, 2000Assignee: DaimlerChrysler AGInventors: Christian Heiselbetz, Dieter Kalweit, Thomas Klaiber, Uwe Kleinecke, Kurt Maute

Patent number: 5724942Abstract: The invention provides a method and apparatus for engine torque regulation in which, for rapid engine torque reduction, fuel injection is cut out using a cutout pattern that can be selected from a predetermined set of cutout patterns, as a function of the deviation of the engine torque. According to the invention, an engine-torque-reducing throttle position intervention is also implemented parallel to the fuel injection cutout. The difference in torque between a load-indicated actual engine torque (derived from an engine air volume measurement) and the required set engine torque can be regulated with an appropriate reduction of the degree of injection cutout in stages.Type: GrantFiled: December 13, 1996Date of Patent: March 10, 1998Assignee: Mercedes-Benz AGInventors: Kurt Maute, Wolfgang Strauss, Hartmut Weckermann

Patent number: 5635771Abstract: In the case of an electrical wiring for a motor vehicle having a primary system which includes a voltage-controlled generator, a primary energy accumulator as well as at least one primary energy consuming device, and having a paralleled secondary system which includes a secondary energy accumulator as well as at least one secondary energy consuming device, the secondary system includes a control unit with a controllable resistor connected to the generator. The control unit monitors the charge condition of the secondary energy accumulator. As a function of the currently determined charge condition of the secondary energy accumulator, the control unit, on the one hand, controls the controllable resistor in such a manner that, during the charging of the secondary energy accumulator, the primary system is not overloaded.Type: GrantFiled: June 23, 1995Date of Patent: June 3, 1997Assignee: Bayerische Motoren Werke AGInventors: Rainer Mertl, Erhard Otto, Walter Streit, Kurt Maute, Wolfgang Zag, Dirk Katzenellenbogen

Patent number: 5467750Abstract: In a method of providing a desired output torque for an internal-combustion engine a desired air mass-flow value or a desired load value is determined from a desired output torque value in dependence on the engine speed and the throttle-valve opening angle, and the measured actual value is adjusted to the respective desired value by control of the throttle-valve opening angle. A conversion between load and air mass flow takes place by means of a load filter which compensates for the deviations, occurring in dynamic operating states, of the measured air mass flow from the air mass flow actually flowing into the combustion chamber of the engine and a transition between the two regulating methods can take place continuously or in a switched manner.Type: GrantFiled: May 11, 1994Date of Patent: November 21, 1995Assignee: Mercedes-Benz AGInventors: Hans Braun, Ulf Weinecke, Kurt Maute, Wolfgang Strauss
