#video | Help system pedestrian detection to avoid accidents?
Source:
Statistics show that in 2017, the cars hit 5 977 pedestrians, while in 2009 this figure was much lower — there were about 4 of 109 incidents. To reduce the number of accidents, car manufacturers equip their systems detect pedestrians, which the sudden appearance of people on the road automatically include a brake. Researchers from the Insurance Institute for highway safety (IIHS) decided to test the effectiveness of these systems, after a very stressful test, which was videotaped.
The system of recognition of pedestrians is in the models with the function of automatic driving. For continuous scanning of the road for the presence of pedestrians uses two sets of sensors: cameras mounted on the rearview mirror, and sensors on the front grille. A special algorithm determines whether it is located ahead of the object is a pedestrian and assesses the risk of collision — if it is high, the system includes a brake with a higher speed than human reaction.
According to the Manager at the active IIHS safety tests David Alora, reduced human reaction to sudden pedestrian is associated with a low concentration. The software of the car there are no distractions, so in any case it will react much faster.
To verify this, the Institute conducted a test with the participation of 11 SUVs with brake function when you encounter pedestrians. In its framework, the researchers have recreated some dangerous scenarios.
thethe Three most common situations when a car knocks down a man:
the-
the
- adult facing the street on the right side; the
- child run out into the street from behind two parked cars; the
- an adult, going back to the road and away from traffic.
The Study showed quite soothing results. Instant response to pedestrians showed four SUV: Honda CR-V, Subaru Forester, Toyota RAV4 and the Volvo XC40. Five models grazed pedestrians, but still are unlikely to have caused serious damage: Chevrolet Equinox, Hyundai Kona, Kia Sportage, Mazda CX-5 and Nissan Rogue. The worst results showed the Mitsubishi Outlander and BMW X1 — on their braking system is better not to rely on.
Do you Drive a car, and do you think the function of braking before the pedestrian extremely necessary? Your opinion write in the comments, and to discuss other automotive topics .
