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

Mazda BSD Tx Chip PWM controlled antenna problem solved

immediately using data acquired by the ATS

Conclusions:

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