[YesAuto technology] Nowadays, pedestrian protection has received more and more attention from auto manufacturers. Friends who are familiar with our article must also know that in the European E-NCAP crash test, there is a passive safety crash test for pedestrian protection. However, many new cars are now equipped with pedestrian detection and AEB active braking systems, which can kill most collisions with pedestrians, bicycles, and motorcycles in the cradle. Therefore, E-NCAP officially stated that in 2016, a new “play” will be introduced to evaluate the vehicle's active pedestrian protection system.
● Traffic accident analysis
● How does the vehicle realize active pedestrian protection
At present, more and more advanced driving assistance systems in automobiles appear in people’s sight. Pedestrian detection and AEB active braking systems can predict the occurrence of danger in advance and automatically brake, even if accidents cannot be completely avoided. Reduce collision damage to a minimum.
Vehicles mainly use cameras installed on the windshield to monitor the conditions of pedestrians, self-propelled people, motorcycles, etc. on the road ahead in real time. Once there is a possibility of danger, the car will give an audible and visual alarm to inform the driver. If the driver does not take any action to avoid the danger, the car will take the initiative to brake.
● How does E-NCAP test active pedestrian protection
The plan of the European E-NCAP collision center plan is to simulate a real collision accident. It mainly designs three scenarios to test the AEB active pedestrian protection function. They are for middle-sized adults walking and running into the driving route and 6-year-old children. From the scene of passing behind the car, test whether the vehicle will collide with a pedestrian or the severity of the collision.
■ Simulate adult walking intrusion
■ Simulate adult running intrusion
The simulated adult running intrusion test is the same as the adult walking intrusion scenario, but the adult dummies break into the driving route faster, so the test vehicle must actively brake in a shorter time.
■ Simulate children breaking in from behind the car
If you think the above two scenes are not difficult enough, then the following simulation of children entering from behind the car will let you see its higher requirements for the vehicle's pedestrian detection ability, computer response speed and automatic braking system response. .
● New plan for E-NCAP in the future
The European E-NCAP test center stated that it will implement this AEB active pedestrian protection test project in 2016. In addition, it also plans to carry out the AEB active braking test on bicycles, the AEB active braking test at intersections, and the updated AEB in the future. High and low speed brake test, etc. This means that with the continuous upgrading of car driving assistance system technology, E-NCAP will also keep up with the pace of testing them.
In the European E-NCAP's active pedestrian protection test plan, the pedestrian detection of the vehicle and the AEB active braking system are integrated through the simulation of the adult walking, running through the intrusion driving route and the child intruding into the pedestrian route from behind the car. Pedestrian protection capabilities. It is conceivable that in the future, if car companies want to get five stars in E-NCAP, they will have to accept more project challenges. This has also led car companies to show more humane care for the fragile lives on the road.
