20090112426 | Method and device for detecting a malfunction of a control coupling - A method for detecting a fault in a coupling having the coupling elements that are movable against each other, which are situated between a first drive unit and a second drive unit, having the steps of providing a torque by the second drive unit, activating the coupling so that the coupling elements are moved into a position which, in the normal state of the coupling, corresponds to a touch point position which corresponds to a position of the coupling elements in which, in the normal state of the coupling, the coupling elements lie against each other, but no torque is able to be transmitted between the coupling elements, determining, after the setting in of the touch point position, whether a torque is being transmitted from the second drive unit to the first drive unit via the coupling, as well as detecting a fault in the coupling if it is determined that a certain torque is being transmitted via the coupling. | 04-30-2009 |
20110180337 | Method and Device for Operating a Vehicle Having a Hybrid Drive - A method and a device for operating a vehicle having a hybrid drive are described, in which a first drive unit and a second drive unit contribute jointly or individually to the drive of the vehicle, the first drive unit driving the second drive unit in the manner of a generator for charging an energy storage device, the first drive unit and the second drive unit being separable by a drive train element transferring a torque of the first drive unit. In a method in which it is ensured that the vehicle may continue to drive safely even in the event of a defect in a drive train element between the first drive unit and the second drive unit, the torque portion used for charging the energy storage device is reduced to a minimum torque, while the torque excess, which is reduced in the event of a defect in the drive train element but still exceeds the minimum torque, is utilized to propel the vehicle. | 07-28-2011 |
20110238253 | Method and device for checking the function of an engine system - A method for checking the function of an engine system having an internal combustion engine includes: (a) ascertaining a first charge adaptation value for acting on a manipulated variable for setting an air supply to the internal combustion engine, and ascertaining a first mixture adaptation value for acting on a manipulated variable for setting a fuel supply at a predefined first operating point of the internal combustion engine, in each case with the aid of a predefined adaptation method; and (b) establishing that an error is present in the engine system when at least one of the offset adaptation values is outside a particular predefined adaptation value range. | 09-29-2011 |
20120109430 | Method for the fail-safe operation of a hybrid vehicle for the controlled initiation of a substitute measure allowing an operation of the vehicle under emergency conditions, and device for implementing this method - A method for the fail-safe operation of a hybrid vehicle having an internal combustion engine, an electric motor, and additional vehicle assemblies. A substitute measure that then still allows the vehicle to be operated under emergency running conditions is initiated if a vehicle assembly fails. A performance quantity that is characteristic of the driving-dynamics situation in which the vehicle finds itself is recorded prior to initiating the substitute measure, and is compared to at least one limit value. The substitute measure is initiated if the limit value is exceeded or not attained. A device which includes a device for implementing such a method is also provided. | 05-03-2012 |
