A power-distributing device for a vehicle electrical system of a motor vehicle may include at least a first power source terminal and a second power source terminal, at least a first safety supply terminal and a second safety supply terminal, a coupling unit to electrically couple the power source and safety supply terminals, and, for each of at least two power source terminals, a source switching element is to electrically couple the first and second power source terminals to the coupling unit, depending on a switching state. In an example, the power-distributing device may have, for each of at least two safety supply terminals, a supply switching element to electrically couple the first and second safety supply terminals to the coupling unit (), depending on a switching state.

Power-distributing device and motor vehicle

A power network for a motor vehicle includes a first partial power network connected to a supply potential, a second partial power network, and a coupling element which couples the second partial power network to the supply potential via the first partial power network. The coupling element has a reversible disconnect function, such that the coupling element reversibly decouples the first partial power network from the second partial power network based on a physical value of the first partial power network.

In a change from a lean to a rich exhaust gas mixture, a characteristic behavior appears in a short time interval in the vicinity of the lambda jump of an upstream catalytic converter lambda probe in the signal characteristic which is measured by a downstream catalytic converter lambda probe. From the signals in small intervals, around the instant of changing, the reliability performance of the downstream lambda probe can be deduced without the actual probe jump in curves of the voltage characteristics having to be considered.

Method for diagnosing the reliability performance of a jump probe

During the measurement of the oxygen storage capacity of an oxygen storage system, which is assigned to a catalytic converter, a switchover operation from lean to rich exhaust gas or vice versa is effected. The measurement signals of a lambda probe are recorded; and an integral calculation is carried out over a time interval on the basis of the measurement values. Whereas in the past the start of the time interval was the point in time of the switchover operation, the present invention provides that the start of the second time interval is determined on the basis of the measurement signals of the second lambda probe i.e., the point in time is preferably fixed at the time at which these measurement values reach an extreme value. This design allows the oxygen storage capacity to be measured even if the lambda probe is not fully functioning totally correctly.
