BMW launches new active safety system to avoid accidental collisions with pedestrians

When you are driving on the road, children suddenly run out from the sides of the road where cars are parked. This is definitely a nightmare that makes all drivers break out in a cold sweat! German research data shows that in accidents where vehicles hit pedestrians, up to 40% of the drivers did not pay attention to the pedestrians on the road and react before hitting them, which made the injuries more serious.

Now, in response to the above-mentioned accidental pedestrian collisions that have long plagued drivers, BMW's vehicle technology team, Germany's top research units, and the transportation, public construction and technology departments of the Bavarian state of Germany have formed a three-year joint project called AMULETT. The motivation for the development of this project is to actively avoid pedestrian collision accidents and reduce the degree of pedestrian injuries through the integration of data transmission and tracking technology between pedestrians and vehicles. Now the AMULETT research project has concrete results. This set of human-vehicle communication technology named Car-2-X Communication will be publicly unveiled on May 6.

『Using RFID wireless radio frequency identification system』

The core design of this system is to build a dedicated RFID radio frequency identification system for pedestrians and vehicles. In the RFID system architecture of the AMULETT project, wireless electronic tags (Radio Transporter) can be built into school bags, mobile phones, canes and other items that pedestrians often carry. The planned test vehicles are equipped with readers (Reader), which continuously emit 2.4 GHz radio frequency electromagnetic waves during driving. At this time, if the electronic tags carried by pedestrians are within the electromagnetic wave sensing range, they will continue to send the chip data in the electronic tags back to the on-board reader. At this time, if the RFID system detects pedestrians entering the vehicle's driving route, it will immediately warn the driver to pay attention to pedestrians through the vehicle's HUD head-up display alarm system, so as to avoid collisions with pedestrians or reduce the degree of collision damage by evading and braking .

BMW, which currently has a number of active safety designs , can make the Car-2-X Communication technology, which is the result of the AMULETT project, more mature in the experimental system in Bavaria. Perhaps the Car-2-X Communication system will have a chance to be popularized around the world in the future. By then, we will have the opportunity to see breakthrough progress in the field of active safety for pedestrians and vehicles.
