METHOD FOR TESTING ELECTRONIC CONTROL UNITS OF AIRBAG PROTECTION DEVICES AND TESTING MACHINE DESIGNED TO IMPLEMENT SAID METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240011873 titled 'METHOD FOR TESTING ELECTRONIC CONTROL UNITS OF AIRBAG PROTECTION DEVICES AND TESTING MACHINE DESIGNED TO IMPLEMENT SAID METHOD

Simplified Explanation

The present invention is a method for testing electronic control units (ECUs) of airbag protection devices. The method involves providing a dataset representing simulated movements in a three-dimensional space, filtering the linear acceleration measurements of the dataset to remove low frequencies, uploading an activation algorithm on the ECU to identify danger situations, programming the ECU to send and/or record an activation signal when a danger situation is identified, moving the ECU within a three-dimensional workspace to replicate the filtered dataset, and verifying if an activation signal is sent and/or recorded by the ECU when a danger situation is identified.

  • The method involves providing a simulated dataset of movements in a three-dimensional space.
  • The linear acceleration measurements of the dataset are filtered to remove low frequencies.
  • An activation algorithm is uploaded on the ECU to identify danger situations.
  • The ECU is programmed to send and/or record an activation signal when a danger situation is identified.
  • The ECU is moved within a three-dimensional workspace to replicate the filtered dataset.
  • The ECU's response is verified by checking if an activation signal is sent and/or recorded when a danger situation is identified.

Potential applications of this technology:

  • Testing and validating the functionality of electronic control units in airbag protection devices.
  • Ensuring the reliability and effectiveness of airbag systems in real-world scenarios.
  • Improving the safety standards of airbag protection devices.

Problems solved by this technology:

  • Ensuring that electronic control units accurately identify danger situations and activate the airbag protection devices.
  • Providing a reliable and controlled testing environment for airbag systems.
  • Minimizing the risk of malfunctioning airbag systems in real-world scenarios.

Benefits of this technology:

  • Enhanced safety for vehicle occupants by ensuring the proper functioning of airbag protection devices.
  • Cost-effective testing method compared to real-world crash tests.
  • Efficient and controlled testing process for electronic control units.
  • Improved quality control for airbag systems.


Original Abstract Submitted

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. the invention also relates to a testing machine designed to implement said method.
