An integrated circuit having a housing in a control unit provides at least two voltage levels, has a watchdog for monitoring a processor, performs an evaluation of at least one acceleration signal to enable at least one ignition output stage, and has at least one first interface for connecting to at least one sensor situated outside the control unit.

Integrated circuit in a control unit, and a control unit for activating a passenger protection arrangement

A method for commissioning a sensor series circuit configured in a daisy chain topology. A second sensor being downstream from a first sensor. The method includes furnishing a first switch signal to the first sensor to close the first switch, the first switch signal being furnished in response to a successful initialization of the first sensor, monitoring a function of the second sensor during initialization of the second sensor to ascertain whether the second sensor exhibits a fault upon initialization or is initialized correctly, and to furnish a fault signal if it is ascertained that the second sensor exhibits a fault upon initialization; and outputting a suppression signal to the first sensor if the fault signal has been furnished, to prevent the first switch from being closed.

A device for supplying an ignition current from an energy reserve to at least one ignition power module, a voltage regulator being provided between the energy reserve and the at least one ignition power module, setting a voltage on the at least one ignition power module at a predetermined level.

A method for detecting a hot start situation in an internal combustion of a motor vehicle includes the steps of determining a gradient of a temperature variation of an engine temperature; and detecting a hot start situation based on the determined gradient of a temperature variation of an engine temperature. An appropriate electronic control unit for an internal combustion engine is provided, as well as an appropriate computer program with a program code mechanism, and an appropriate computer program product with a program code mechanism.

Method for determining a hot-start situation in an internal combustion engine

An internal combustion engine, especially for a motor vehicle, is described which is provided with a combustion chamber into which fuel can be injected in at least two operating modes. A control apparatus is provided with which a switchover can be made between the operating modes in dependence upon a desired operating mode. With the control apparatus, an operating-mode request can be determined in dependence upon whether the individual operating modes are in the position to generate the requested torque while maintaining pregiven lambda limits.
