[YesAuto Safety Technology] 3 years ago, my colleagues went to Japan to participate in the Honda Media Conference and tested the discontinued NSX TYPE S; 2 years ago, they came to Utsunomiya to test drive the TYPE R which was still in the development stage; A year ago, I missed the opportunity to come here to witness the car-to-car crash test. This year, the Honda Institute of Technology in Utsunomiya finally opened its doors to me. What new technologies are waiting for me this time?
Speaking of Utsunomiya, you may not be familiar with it. There are few electrical appliances stores and department stores favored by tourists, and when it comes to places of interest, Utsunomiya Castle, Songbong Church, and Kiyogwan Temple Towers are far from Mount Fuji, Sensoji Temple, and Golden Temple. The pavilion is like Lei Guaner. Therefore, it is really difficult to attract tourists.
After reading the above introduction, I think most people will be as curious as I am about what research the members here are doing. However, it is a pity that due to confidentiality reasons, it is forbidden to take pictures during the whole tour, so most of the pictures in this article are provided by the official, please forgive me.
Before the trip, my colleagues were just like Xianglin’s wife showing off what classic cars they drove here. Therefore, when I opened the itinerary and noticed that there was no opportunity to test drive those classic cars during this trip, I can't help but feel a little lonely. However, this time there is an opportunity to learn about the safety of the Honda brand. I think this is not bad news.
In fact, the safety of vehicles can be divided into two parts, namely passive safety and active safety. In the foreseeable years, even if vehicle active safety technology continues to develop, collision accidents are still unavoidable. Therefore, studying the performance of the vehicle at the moment of impact, in other words, studying how to make the vehicle safer in a collision accident has become the top priority of each car company's research and development.
Passive safety technology
● Vehicle-to-vehicle collision
For vehicle research and development, passing collision detection in various places is only a passing line in its development tasks. Accidents in the real world are ever-changing. Therefore, the goal of the body structure designed in the experiment may be to try to avoid accidents outside the design. At the same time, the safety of the occupants can still be guaranteed to the utmost extent. In reality, accidents are not always cars colliding with fixed obstacles. This is the significance of today's car-car collision experiment.
Now is the time to answer the above questions. In the collision test and actual accidents, the damage of the smaller mass is indeed serious. According to statistics, the probability of death and injury is indeed higher than that of the larger mass model. Therefore, Honda has introduced an ACE structure body that can absorb and guide more impact energy and has a larger protection range. It is precisely because of its reasonable design that it has achieved good results in recent crash tests.
In today's increasingly complex traffic environment, the research and development of car companies on vehicle safety has long been not limited to protecting the drivers and passengers in the car. As a vulnerable group participating in the traffic, pedestrians are also one of the research focuses. When we collide with these “reinforced and iron” guys, our weak bodies have to bear a huge impact. So how does the vehicle cleverly absorb as much impact force as possible to protect pedestrians through structures, materials, etc.? Perhaps the experiment on the next page is one of the answers.
● The vehicle collides with the dummy
In real life, the situation when pedestrians collide with vehicles is also ever-changing. The task of R&D personnel is to reduce the impact force on pedestrians as much as possible through vehicle structure and material design. At this stage, it is unlikely that pedestrians will be injured in an accident. The goal of R&D personnel is to reduce the degree of injury as much as possible.
This time the car and dummy collision test experiment car used Honda Vezel, and its domestic model is Binzhi. In this experiment, it will hit the dummy at a speed of 40km/h. According to statistics, this speed is currently a frequent occurrence area of collision accidents.
When the dummy's legs and knees are deformed due to force, the front bumper of the vehicle is also deformed due to the impact force. This kind of deformation transmits the impact force to the anti-collision beam, so as to absorb energy and reduce the probability of pedestrian injury.
In the process of pushing away, we can see that the engine compartment cover has been deformed, which shows that it has absorbed the impact energy of the dummy's torso and head, and finally made a contribution to reducing the probability of injury of the dummy.
Friends who often watch collision experiments must be familiar with dummies. These “guys” with sensors hidden in the head, neck, torso, legs, and knees take the place of us to accept the experiment and give feedback on the collected data. It is because of their repeated collisions inside and outside the car that we have driven a mass-produced car that complies with regulations and safety standards.
Friends who are familiar with Honda know that this is definitely an enterprise that is not doing business properly. The design and manufacture of motorcycles and automobiles is just one of its business areas. It can be seen from civil jet airliners to lawn mowers. Figure. In such a broad business field, Honda is still conducting research on robots.
Active safety technology
After reading passive safety technology, let us look at active safety technology. Twenty years ago, if someone told me that the vehicle could detect the surrounding environment and actively slow down or brake, I would definitely think that he had watched too many science fiction movies or was crazy. However, today, 20 years later, more and more vehicles are beginning to be equipped with these technologies.
● New direction of CMBS technology
Honda’s CMBS technology belongs to the initial stage of autonomous driving. We have experienced related technologies last year. If you are relatively new to it, I suggest you click here to read the “Assisted Driving-Based Honda Motor Safety Technology Experience”. We will no longer here. Go into details. Today, we see the new functions being developed in the CMBS system, which is one of the cornerstones of the future fully automated driving technology.
Honda’s DSRC (Dedicated Short Range Communication) technology uses millimeter-wave radar, cameras, GPS, and DSRC antennas to detect the surrounding environment. Motorcycles used as traffic participants will also join DSRC and antennas for transmission. , The function of receiving signals, and the most vulnerable humans do not need to carry an antenna. As long as a specific chip and program are installed in the mobile phone, the signal transmission and collection can be completed.
In addition to the DSRC mentioned above, the CMBS on the vehicle, that is, the collision mitigation braking system, has also been updated and expanded. When the vehicle detects the presence of a pedestrian in the blind spot, it will apply a reaction force to the brake pedal to inform the driver that there is a pedestrian in the blind spot so that it can react early. At the same time, pedestrians with related apps on their phones will also receive warning messages.
Full text summary:
When I came to Utsunomiya this year, what was waiting for me was not the test drive activities of classic models, but the safety tests one by one. In a very limited time, we generally glanced at a small part of the technology developed by the Honda brand.
Since the birth of the car, its safety has attracted people's attention. With the development of technology in recent years, active and passive safety technologies such as energy-absorbing structures, high-strength materials, and anti-collision warning have come to our side. Taking the opportunity of this safety technology experience, we once again saw the ACE structure body that performed well in the crash test, and also saw Honda's new technology in active safety. However, due to time constraints and other reasons, we are a little regretful that we did not see a prototype car with fully automatic driving technology. I hope that this time next year Honda Giken will give us new surprises in Utsunomiya. (Part of the pictures from the Tang Dynasty of Wenqijiajia comes from official sources)
