A driver assistance system and method for operating a driver assistance system, the driver assistance system provides a plurality of distance sensors, in particular ultrasonic sensors, which are spatially distributed and communicate with each other with the aid of a data bus. The sensors have an identical design and may be initialized by themselves using a method without a control unit and may synchronize the distance detection among themselves. The overall result of a measurement of the sensors is supplied to an output unit and displayed to the driver.

Driver assistance system and method for operating same

A sensor system for determining distances is provided. A predefining unit controls an amplifier unit and/or a sensor unit as a function of selectable predefined values for a detection cycle. Contrary to known sensor systems, different detection cycles are implementable in a simple manner using this procedure.

Sensor system and method, in particular for determining distances

In order to create a method for eliminating dummy objects in short-range pulse radar sensors, in which radar pulses are transmitted at a defined frequency, and the time until they are reflected by an object and received again is measured, and besides the transmitted pulse (TX pulse), a delayed second pulse (RX pulse) is generated, which avoids the known disadvantages of the prior art and with which the elimination of dummy objects in short-range pulse radar sensors can be assured, it is provided that the transmitted pulses (TX pulses) and the additionally generated second pulses (RX pulses) delayed relative to them are modulated by a binary phase-shift keying process.
