Enhancing Pedestrian Safety| Innovative Technologies in Modern Vehicles
Occupants of Modern Vehicles are protected from accident damage and injury with many solutions such as special body structures, seat belts, airbags, and many electronic assistance systems, but what about pedestrians and road users who walk on their feet without the slightest protection?
Pedestrians are exposed to double risks when an accident occurs, because they are almost unprotected on the street, and there is nothing to help them except caution and their common sense, which has called for the development of a number of technologies and systems that monitor pedestrians and are not satisfied with inactive protection in the body of the car.
One of these technologies is what is known as “pedestrian recognition with emergency braking function.” This technology automatically brakes the car when it recognizes a pedestrian in the moving range.
Since not all accidents can be avoided, especially at high speeds, many manufacturers combine these systems with an automated maneuvering assistant. If this system recognizes an object or person on the road and fears a collision, it supports the driver in parallel with emergency braking at the correct steering angle.
Improve vision in the dark
Other assistance systems aim to protect pedestrians mainly by improving visibility in the dark. For example, Peugeot and Citroen use infrared cameras with special image recognition and highlighting those in danger on the screen.
In another strategy, Audi is programming smart headlights in a way that specifically shows pedestrians on the edge of the road at night to warn the car driver.
If there is contact between the body and the vehicle chassis, despite all these precautions, the protection of pedestrians remains inactive. Mercedes spokesman Koert Groeneveld explained that he intervenes deeply in the design and construction of vehicles, including the non-rigid front, and the heights of the engine compartment lid and fender edges are calculated and tested using crash test dummies so that serious injuries are avoided as much as possible and the impact on the body is minimal. As light as possible.
External airbags in Modern Vehicles
For his part, Robert Buchmeier, from ZF, a supplier of automotive parts, confirmed that some models contain airbags on the outside of the engine compartment cover and in front of the windshield to provide more protection in the event of a collision.
A relatively new technology for protecting pedestrians is the sound generator in electric cars. Since there is no sound in an electric car, it requires a “vehicle audio alert system” to issue a warning tone that can be heard up to about 20 km/h.
But protecting pedestrians should not only be in the Modern Vehicles. So LG introduced the beta version of a smartphone app that monitors real-time motion and location data and can warn users if they are on a collision course.
Researchers from the Fraunhofer Institutes also rely on external intelligence and have developed a radar sensor system that can monitor pedestrians and warn road users before there is danger, as electronic systems create profiles and forecasts of movement, and raise an alarm when a pedestrian approaches the road.
FAQs:
What is pedestrian recognition with emergency braking function in Modern Vehicles, and how does it work?
This technology automatically brakes the car when it recognizes a pedestrian in the moving range, providing an additional layer of safety for pedestrians on the road.
How do some automakers improve pedestrian visibility of Modern Vehicles in the dark?
Manufacturers like Peugeot, Citroen, and Audi employ technologies such as infrared cameras and smart headlights to enhance visibility in the dark and warn both pedestrians and drivers about potential hazards.
What measures do car manufacturers take to reduce the impact on pedestrians in the event of a collision?
Car makers, such as Mercedes, invest in vehicle design and construction, including non-rigid fronts and carefully calculated heights of engine compartment lids and fender edges to minimize injuries to pedestrians during accidents.
What role do external airbags play in protecting pedestrians of Modern Vehicles during collisions?
Some vehicles feature external airbags on the engine compartment cover and in front of the windshield to provide additional protection in case of a collision.
How are smartphone apps and radar sensor systems contributing to pedestrian safety?
Smartphone apps, like LG’s beta version, monitor users’ real-time motion and location data to warn them of potential collisions. Meanwhile, radar sensor systems developed by Fraunhofer Institutes can detect pedestrians and alert road users to potential dangers in advance.
Conclusion
In today’s world, where automotive technology is advancing rapidly, the safety of pedestrians on the road is receiving increasing attention. While modern vehicles are equipped with numerous features to protect their occupants, it’s essential to address the vulnerability of pedestrians who lack the protective structures of a car. Innovative technologies such as pedestrian recognition with emergency braking function, improved visibility in the dark, external airbags, sound generators in electric cars, smartphone apps, and radar sensor systems are all contributing to enhancing pedestrian safety.
These advancements represent a significant step forward in minimizing the risks faced by pedestrians. By alerting drivers to potential dangers, automating emergency maneuvers, and implementing protective measures, technology is making our roads safer not only for those inside the vehicle but also for those outside it. As we move forward, it is crucial to continue exploring and adopting such technologies to reduce accidents and protect pedestrians from harm.
