The article describes some algorithms for collision detection used in modern cars airbag systems. While controlling the activation of airbags and other passive safety systems, installed in modern vehicles, the algorithms must operate in the early stage of accident, because for operating effectively it is necessary to run control systems early enough, for example filling airbags before the body of the driver or passenger reaches the zone of airbag. These algorithms could be applied into the on-board eCall modules, but they would require calibration. Detection of the collision that activates eCall system must be made on the basis of measurable signals or observable events, which intensity can be relatively clearly linked to the probability serious injury of the driver and the passengers’ of the vehicle. A table summary presented in this article contains a description of the collision detection algorithm along with a brief description of the method of detection and description of the used methodology. A frequently used method is to evaluate the gradient of the change of speed - the parameter ..V, or its combinations with different parameters, such as the derivative of acceleration, displacement, and energy of the collision. Each of the algorithms has been briefly described. The whole of article is summarized with the conclusions arising from its content.
