Abstract: The present invention relates to a method for testing electronic control units of airbag protection devices. The method comprises the steps of: a) providing a dataset (D) representing simulated movements in a space defined by three axes (X, Y, Z); b) filtering the linear acceleration measurements (Ax, Ay, Az) of said dataset (D) to remove low frequencies; c) uploading on the electronic control unit to be tested an activation algorithm capable of identifying a danger situation for the user; d) programming the electronic control unit to be tested to send and/or internally record an activation signal when the activation algorithm identifies a danger situation; e) moving the electronic control unit within a three-dimensional workspace (W) to replicate said dataset (D) as filtered in step b); f) verifying if an activation signal is sent and/or internally recorded by the electronic control unit when the activation algorithm identifies a danger situation.
