A crucial capability of side pre-crash systems is the correct functioning of pre-crash sensing and actuator triggering. Under the EU-funded Integrated Project APROSYS, a crash under controlled conditions will be carried out in January 2008 as part of a generic test suite. In order to gather relevant sensor data for preparation of the test, a test rig has been built that allows for non-destructive tests of side pre-crash sensing and actuator triggering in the developing phase. During a data collection, stereo video and radar sensor data are acquired of a moving barrier. Simultaneously, high-quality reference data from independent sensors are acquired. The acquired data were then used to semi-automatically produce ground and sensor truth data. In this contribution, the APROSYS test rig and the instrumentation of the data collection as well as the resulting Benchmark data are described. The Benchmark data allow for a fine-tuning of important precrash sensing performance parameters in the crash test facility, i.e. probabilities of detection and false alarms, as well as the correct timing of actuator triggering. Further data collections will be carried out using robotic vehicles in order to reproducibly generate additional variations of the bullet object trajectory, and under real-world conditions during a several days' drive on European roads.
