European new car safety assessment organization Euro NCAP testing in addition to the security performance of the new car, in fact, since the beginning of 2010, also contributed to the Euro NCAP Advanced Reward Advanced Safety Award, from time to time on the latest novel, can also help create a more secure vehicles, traffic environment of technology for evaluation, and give praise to Ziken given. The issue before a return from Euro NCAP Advanced Award for Safety has to be traced back to 2014, and now after a lapse of six years, then there is certainly the public to obtain Euro NCAP award. The award-winning technology but a quot; Local Hazard Warningquot; (provisional translation: environmental risk warning system) of V2X technology innovation, original representation may help drivers prevent accidents, wireless connections with other vehicles and transportation facilities, and equipped with first to 8-generation Golf.
Local Hazard Warning: car networking help volume applications Preview road environment
over the past few years, already there have been car networking You can help to create the concept of a safer traffic environment, but has been used almost only limited network, presentation or technology exhibition, the actual production application cases rare. However, Volkswagen developed a Local Hazard Warning environmental risk warning system is a V2X technology, and is equipped to 8-generation Golf, also became the first European market a technology standard Car2X car. The technology is based on Wi-Fi p wireless standard, called quot; ETSI ITS-G5quot ;, this type of Wi-Fi specially tailored for communication between vehicles, rather than using a mobile phone network, which means it It is run in the protected frequency ranges. No more than 800 meters in radius of the vehicle can be positioned directly exchange data and messages with other facilities or vehicle.
8-generation Golf has become the first European market a technology standard Car2X car.
and the system is adapted to limit the context
present the public this environmental risk warning system mounted on golf, if encountered the following eight kinds of situation, there will be the same with other environmental risk warning system of the vehicle was issued message:
1 in front of the vehicle associated with the active safety actuation. For example: AEB actuated agitated bis flashing yellow light, etc.
2. static vehicle
3. Fault vehicle [ 123]
4.
accidents
5.
congestion
6.
roadworks [ 123] 7.
stationary emergency vehicles
8.
passing emergency vehicles
for example: there are a few hundred meters in front of the police when there is an ambulance or rear, the system will notify the vehicle pull over to let the ambulance travel; vehicle broke down or in case of other accidents that can warn each other within a few milliseconds dangerous situation, or contact notified of road works and so on. After the German ADAC test, the system will usually make a reminder in 10 to 11 seconds before the accident about to happen. Always, the vehicle equipped with this system can be set to send or receive messages, the system will be in accordance with the distance, the urgency of the event, informed in advance of the divided message, or turn warning, to remind drivers pay attention to traffic, increased road use safety.
As for this environmental risk warning system, subject to the limitation that only when the vehicle exceeds 80 kilometers per hour, will be issued a warning to the driver, which is mainly to solve Europe country road or a high-speed highway speeds, it is often difficult to advance the more attention or may react less serious accidents caused. Actually in an urban environment, the public believed the driver’s attention is usually higher and higher traffic density has also been advance warning of dangerous role. To enable environmental risk warning system, the owner must in Europe after delivery of the vehicle, according to the European GDPR common data protection regulations, to accept the data protection agreement in order to use the set system.
prevention is better than cure of safety equipment, but for how the future safety benefit depends on how many vehicles are equipped with
In retrospect Euro NCAP awarded the prize of science and technology with advanced security, will make a quot; safety Benefitquot; assess the safety benefits, including the most recent is the 2014 BMW AEB pedestrian warning, Opel blind spot detection warning, etc., will have estimated this vehicle is equipped with the percentage of certain types of accidents can be reduced, and so on. And so far, Euro NCAP awarded through security with technology, almost all implemented in each depot, there are those who are equipped with.
However, this time the public Local Hazard Warning, Euro NCAP safety benefits represent the system can bring, there is not a forecast value, the reason is that this future depends on how many vehicles on the road must have this kind of car networking equipment. Because the Local Hazard Warning is not a simple myself for emergency response vehicles meet the immediate situation to do, but to do remind the whole environment, other vehicles to help predict road traffic have not yet seen, if the system is not popular, the benefit is difficult high.
again the current European average vehicle life of 11 years, it is expected the system to be able to popularize the road every car is equipped with, will need some time. Finally, even if the road vehicles have car networking, but the driver of a mixed reaction will also affect other drivers respond, it also allows security benefits are difficult to quantify. However, Euro NCAP is expected in the future intends to bring technology into Car2X appraisal standards, Volkswagen also said that more new models will come standard with the technology.
