[Ulrich Stählin, Ralf Merzbacher, Marc Menzel, Carsten Birke, Maik Schäfer, Ulrich MÖller] DE,,Eschborn;DE,,Hifheim;DE,,Marburg;DE,,Frankfurt am Main;DE,,Friedrichshafen-Kluftern;DE,,Holzkirchen; An emergency call unit for a vehicle includes not only a detection unit, a position-finding unit and a control unit, but also a transmission unit for the repeated transmission of a locating signal to a rescue worker. In this context, the locating signal may correspond to the position of the vehicle, and the transmission of the locating signal is initiated by a trigger event. By way of example, the trigger event is a request from a rescue worker or is the detection of an accident.

[STAEHLIN ULRICH, BIRKE CARSTEN] DE The device (100) has a control unit (110) for determining a position of a vehicle, where the determination of the position of the vehicle takes place based on position data of position determination units (101, 102) i.e. satellite-navigation receivers. The control unit determines two possible vehicle positions from the position data, where the control unit forms a mean value from the possible vehicle positions. One of the position determination units (102) for detecting the position data is performed on based on a cellular mobile technology. Independent claims are also included for the following: (1) a method for position determination of a vehicle (2) a program element for position determination of a vehicle (3) a computer-readable medium comprising a set of instructions for performing a method for position determination of a vehicle.

The power-optimized cell unit is configured in such a way that it can be used to generate a higher power than with the energy-optimized cell unit. The energy-optimized cell unit is configured in such a way that it can be used to store a higher quantity of energy per volume of the energy-optimized cell unit and/or per mass of the energy-optimized cell unit than with the power-optimized cell unit. The at least one energy-optimized cell unit and the at least one power-optimized cell unit are arranged in a common cell housing.

The C2X communication can be used for recognizing pedestrians. It is also possible to use a plurality of transmission paths and/or UDP.

To this end, the positioning signal may correspond to the position of the vehicle, and the transmission of the positioning signal is triggered by a trigger event. The trigger event can be, for example, an inquiry by a rescue worker or the detection of an accident.

[STRAUSS MATTHIAS, PFEIFFER JUERGEN, SWOBODA ADAM, RUECK ENRICO, LUEKE STEFAN, HEINRICH STEFAN, SEIFERT TIMO, BIRKE CARSTEN, BAIER ROBERT] DE;DE The system has a radar sensor (10) and camera sensor (20), where an object detected by the sensors and determined by object tracking (31, 41) of the sensors is assigned to an object confirmation and situation analysis (42) for verification. Vehicle information and lane prediction (43) are considered for the verification. The analysis (42) determines relevant objects (60), where a measure for increasing a passive security is triggered by the relevant objects and driver information (80) during the detection of a danger situation by a danger processor (90).
