摘要:
Disclosed is a circuit arrangement (10) for recognizing an undervoltage of an energy source (12). Said circuit arrangement (10) comprises a transistor switch (48) and at least one additional switching means (30). The inventive circuit arrangement (10) is characterized in that the transistor switch (48) and the additional switching means (30) have a low resistance in an operational state of the circuit arrangement (10) while the transistor switch (48) blocks the additional switching means (30) in order to interrupt the voltage supply when a supply voltage (U) of the energy source (12) drops below a defined voltage value (US).

A circuit arrangement (10) for detecting undervoltage in an energy source (12) includes a transistor switch (48) and at least one further switch element (30). The transistor switch (48) and the further switch element (30) are of low impedance in an operating state of the circuit arrangement (10). The transistor switch (48) blocks the further switch element (30) for interrupting the voltage supply if a supply voltage (U) of the energy source (12) is below a defined voltage value (Us).

A driver assistance system for a motor vehicle includes output means for outputting information to a vehicle driver of the motor vehicle and/or operating means for operation of the driver assistance system by the vehicle driver, and control means for controlling the information output and/or operation. Means for determining a workload state of the vehicle driver are provided; and the control means are embodied for controlling the information output and/or operation as a function of the workload state of the vehicle driver. A driver assistance system has the advantage that operation of the driver assistance system, and information output by the driver assistance system, are adapted to the workload of the vehicle driver, consequently avoiding overload or excessive distraction of the vehicle driver from traffic events, thus contributing to traffic safety.

A navigation system for motor vehicles includes at least one display device for a pictorial representation of the vehicle surroundings, at least one data memory containing data that allow for a three-dimensional reconstruction of the vehicle surroundings, at least one camera capable of recording digital images of the vehicle surroundings, and at least one data processing unit, which is capable of generating a reconstruction of the vehicle surroundings representable on the display device from the data contained in the data memory, and which is capable of performing an at least partial integration of the digital images recorded by the camera into the reconstruction of the vehicle surroundings, which reconstruction is based on the data contained in the data memory.
摘要:
A method for the transmission of data using radio transmission systems between transmitter/receiver stations is provided, and a computer for the allocation of radio transmission systems for the transmission of data between transmitter/receiver stations is provided, which serve to select radio transmission systems dynamically, for a communication from at least one transmitter/receiver station, on the basis of a subscriber profile, a location of the one transmitter/receiver station, and/or a speed of the transmitter/receiver station, in order to transmit data between transmitter/receiver stations. A computer in a switching device calculates which radio transmission system best meets the criteria. During a data transmission, it is possible to switch automatically to a further radio transmission system if the transmission quality of the radio transmission system currently being used declines.
