摘要:
A method for operating a hybrid vehicle, which has a first and a second drive unit, in which the second drive unit is started by at least a portion of the operating energy generated by the first drive unit. In order to improve the driving comfort of the hybrid vehicle during the startup of the second drive unit while driving, the second drive unit, which is at rest, is started using kinetic energy obtained from a driving movement of the hybrid vehicle, while the hybrid vehicle is driven by the first drive unit.

A method for operating a vehicle electrical system of a motor vehicle, the vehicle electrical system having at least two onboard subsystems having different electrical voltages, and a coupling is provided which allows a flow of electrical energy between the onboard subsystems, the one onboard subsystem being connected to a generator and/or at least one electrical consumer, and the other onboard subsystem being connected to at least one electrical consumer. In the event of a fault, the voltage supplied by the generator is lowered to a value that poses no risk to persons, yet an energy flow from the onboard subsystem having the generator to the other onboard subsystem having the consumer taking place nevertheless.

The spray attachment has a holding part with a water guide that can be connected to a feed water pipe, and a spray head with an external housing. Said spray head and the holding part are fastened separably to each other by means of a coupling. Furthermore, the spray head can have switching options for producing different spray jets, and an illuminating means.

A sanitary fitting includes a light-permeable water-carrying outflow pipe that has (i) an exposed end face and (ii) an input face located upstream of the exposed end face. A light source, preferably including light emitting diodes (LED), inputs light into the outflow pipe through the input face. The light emerges from the outflow pipe at the end face, and may also emerge at an exposed outer peripheral surface area of the outflow pipe. The outflow pipe has a stationary first outflow pipe piece with the input face and a rotatable second outflow pipe piece with the exposed end face.
摘要:
A method for detecting combustion misfires in internal combustion engines on the basis of an evaluation of the segment times is introduced wherein a shaft of the engine passes over predetermined angular segments. The method is characterized by variable segment lengths and/or segment positions relative to a reference point of the movement of the pistons of the engine. The position of the angle segments and/or the segment length, that is, the angular expansion of the angular segments, is dependent upon operating parameters of the engine.

The method serves for input signal correction of a misfire detection function and for cylinder equalization in an internal combustion engine, especially of a motor vehicle. Here, it is provided that a control for the input signal correction (10) and a control of the cylinder equalization (11) are activated alternatively by an alternative circuit unit (12).
摘要:
A method for detecting combustion misfires for internal combustion engines is introduced wherein an index for the rough running of the engine is formed and is compared to a threshold value. The threshold value is dependent upon the load of the engine. Exceeding the threshold value is evaluated as a misfire. The method is characterized in that the threshold value, in addition to being dependent upon the load, is also dependent upon the ignition angle and/or the lambda value or that the formation of the index for the rough running also takes place in dependence upon the ignition angle and/or on the lambda value; and/or that the activation/deactivation of the misfire detection is at least dependent upon the ignition angle and/or on the lambda value.
摘要:
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.
摘要:
A method for operating a hybrid vehicle in the event of a fault in an energy system, the hybrid vehicle being driven by at least two power plants, together or separately, and at least one electric power plant electrically charging a high voltage energy system which supplies a low voltage energy system with electrical energy, a high voltage being converted into a low voltage for supplying at least one control unit of the hybrid vehicle, and the hybrid vehicle being disconnected from the electric power plant when a fault is detected in the high voltage energy system. To maintain the energy supply to the control units via the low voltage energy system even in the event of a fault in the high voltage energy system, the electric power plant is placed in a state for generating a voltage which is uncritical for the safety of the user after the high voltage energy system is disconnected, the safety-uncritical voltage being converted into the low voltage for supplying the at least one control unit.
摘要:
A method and a device are described for starting an internal combustion engine of a hybrid drive train, having an internal combustion engine and at least one additional machine, in particular an electric machine, a separating clutch, which is situated between the internal combustion engine and the additional machine, and a crankshaft angle sensor for detecting the instantaneous crankshaft angle of the internal combustion engine being provided. Arrangements are provided to perform the following operations to start the internal combustion engine when a high-voltage battery is essentially discharged, including a) the separating clutch is or has already been disengaged, b) the additional machine is accelerated, c) after conclusion of the acceleration operation of the additional machine, the separating clutch is engaged, so that the internal combustion engine is also accelerated, d) as soon as the crankshaft angle sensor system supplies a favorable crankshaft angle, the internal combustion engine is started by direct start.
