Computer-implemented method for automated analysis of crash data

A computer-implemented method for automated evaluation of crash test data comprising the steps of:

• reading a data set with crash test data from a plurality of available data sets;
• extracting from the data set time-dependent force signals that are attributable to a seatbelt tensioner of a passenger restraint system of a vehicle;
• calculating changes in force ΔFi from the force signals at fixed or determinable time intervals between 0.05 ms and 0.15 ms, up to a time threshold between 23 ms and 27 ms starting from a time of vehicle impact on the barrier;
• checking whether the change in force ΔFi reaches or exceeds a fixed or determinable threshold value within the time threshold in at least one of the time intervals for determining activation of the seatbelt tensioner;
• and
• changing at least one component of the passenger restraint system based at least partly on a determination in the checking step that the seatbelt tensioner was present and activated.
