The working frequency is 24GHz, the equivalent wavelength is millimeter class,
thus also called Millimeter Wave Blind Spot Sensor.
Current Status on Microwave BSD:
Because of the outstanding performance and technical difficulties of Microwave sensor BSM are mostly adopted in car OEM plant. Currently, around 98% of the microwave applications are for car blind spot detection. Following cars are equipped with Microwave BSD:
Ford, Volvo, VW, Benz, GM, Toyota, Honda, Mazda, etc.
It is expected that in the next 5 years, this system will become car standard parts.
–Valid for moving objects
–By intelligent software configuration, can obtain target car moving speed, and thus judge whether it can cause danger to our car.
–Far detection distance, so can give warning much earlier. –Installed inside car bumper, no need to drill holes.
–Strong anti-interference: Heavy rain, fog, snow nearly has no influence to its performance.
–Valid for anything in range
–Give warning if any object in range.
–Can’t differentiate isolation strip, vehicle, or other object, thus can’t detect real danger, and with lots of false alarm.
–Short detection distance (around 3m), not easy to detect fast passing by object.
–Need to drill hole on bumper, influence car appearance.
Working Mode & Alarming Mode
1. System begin to work when car speed exceeds
2. When turning light is on, the corresponding sensor begin to work.
If there is object within 20 meters from the sensor, and getting closer to the sensor (faster then our car).
1. Turning light OFF: corresponding LED light will be constantly ON.
2. Turning light ON: corresponding LED light flashes (sound optional).
