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
13
Mazda BSD Tx Chip How it works
14
Mazda BSD Tx Chip PWM controlled antenna problem solved
immediately using data acquired by the ATS
15
Conclusions:
Tests and validations of ECUs in short time Complying automotive standards High reproducibility for tests Lower costs for next developed ATS
