Abstract Crash tests are helping the automotive manufacturers to improve the security of the vehicles, and are also useful for validating computer simulations of road traffic accidents. In crash tests are used real vehicles instrumented with sensors that measures speed, forces and accelerations. The human body, pedestrian or vehicle occupant, is replaced with a dummy, also instrumented with sensors. The sensors must be connected to data acquisition systems that are able to record information at high rates and being at the same time shockproof. For different types of tests (vehicle-vehicle, vehicle-pedestrian, lateral or frontal impact) are required different sensor’s characteristics. Some recommendations regarding vehicle instrumentation for impact tests, including data processing, are included in standards like SAE J211. In this paper are presented data acquisition devices used in real tests, and the methods for processing data, including sampling rates and filters. There are used sensors integrated in data acquisition systems from well recognized manufacturers and also sensors mounted in new, original developed systems.
