  1. Faculty of Electronics and Telecommunications Automatic Test System for Mazda BSD Tx Chip Student: Gîdea Marius Iulian Scientific coordinator: Prof.Dr.Ing. Mihaela Lascu Timișoara, 2010

  2. Project requirements: • Develop an automatic test system • Work in automotive temperature range • Use LabVIEW as programming language • ECUs tests and validations • Generate test reports • Easy to modify implemented tests

  3. Automatic test system – block diagram

  4. The test bench:

  5. Personal contributions: • Implement the connecting cable in OrCAD 9.2 • Develop the routing box • Create a map for test points • Design and build the nails adaptor

  6. Personal contributions: • Nails adapter

  7. Personal contributions: • Nails adapter

  8. Personal contributions: • Routing box (front and back panel).

  9. Personal contributions: • Develop the test software in LabVIEW (front panel)

  10. Personal contributions: • Develop the test software in LabVIEW (block diagram)

  11. Personal contributions: • Generate test reports • Run and optimize tests

  12. Personal contributions: • Optimization of the testing times • Create VIs for measuring devices • Develop a CAN communication with the ECU using LabVIEW environment • Assemble the test bench

  13. Mazda BSD Tx Chip • BSD – Blind Spot Detection • The device is a 24 GHz radar • It is mounted in the rear bumper of the car • Warns the driver when there are vehicles in the blind spot of the side-view mirror • Lane changing in the city and on highway becomes safer

  14. Mazda BSD Tx Chip • How it works

  15. Mazda BSD Tx Chip • PWM controlled antenna problem solved immediately using data acquired by the ATS

  16. Conclusions: • Tests and validations of ECUs in short time • Complying automotive standards • High reproducibility for tests • Lower costs for next developed ATS

  17. Thank You
