Abstract
Pre-crash functionality is defined in three functional steps: PRESET, PREFIRE and PREACT. The functional steps are described in the order of growing situation analysis performance requirements and an increasing amount of necessary system application effort. Each functional step defines its own range of view, the so-called virtual barrier. The definition of the virtual barrier is subject to various constraints in respect to sensor configuration and pre-crash performance. A more detailed description of PRESET functionality for frontal pre-crash is given together with a test example.
Pre-crash sensing technology uses platform radar sensors. The platform sensors are designed for the integration of all possible functions that rely on sensor information from the close surroundings of the vehicle. This development approach guarantees a high cost efficiency, flexibility and modularity of the sensor system while still guaranteeing the full pre-crash functionality.
