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.

To protect vehicle occupants in dangerous situations, the distance of the vehicle to a roadside object, such as a guardrail, etc., is determined and compared to a critical distance. If the actual distance is less than the critical distance, alarm devices are triggered and/or reversible restraining devices are deployed. The critical distance may be determined as a function of the host vehicle velocity.
