Last weekend Volkswagen "IDGO Safety Lab" Beijing Station event was held, I participated in the event, and through Volkswagen technical experts to Volkswagen IDA detailed description of the family's security technology, an in-depth understanding of the Volkswagen IDThe security strength of the family. Volkswagen has always had a good reputation for safety and reliability in the Chinese market, and they are also keeping pace with the times, bringing these good genes to the electrification era and to the id. in the process of electric mobility transformationFamily, let's find out.
In the era of electrification, new energy vehicles are more comprehensive and intelligent than traditional models in terms of safety, such as intelligent driving assistance and even future autonomous driving is the pursuit of new energy vehicles, and battery safety is also the most concerned part of new energy vehicles. Just FAW-Volkswagen IDThe 7 Vizzion was also officially launched over the weekend, and he is currently IDThe most comprehensive model of the family safety equipment, let's take him as an example to interpret the IDFamily of security technology.
From everyone's Xi of vehicle cognition, we look at it from the outside to the inside. In fact, the body is also equipped with many sensing devices that we can see or can't see, including multi-function cameras, millimeter-wave radars, ultrasonic radars, image cameras, etc., which cooperate to form an intelligent driving assistance system, which raises the active safety of the vehicle to a new height.
Let's take a look at IQ firstLight LED matrix headlights, it can automatically adjust the lighting form of high beams through intelligent control, especially when the opposite car is coming, it can be automatically adjusted to not shake the other party's light, while illuminating the dark road, reduce the interference of other vehicles' sight, and improve the driving safety of both sides of night driving.
iq.Drive intelligent driving butler sensing components
iq.DRIVE brings a series of intelligent driving assistance functions through the sensing equipment of the body, including full-speed driving assistance system, lane keeping system, intelligent lane change system, emergency braking system, emergency assistance system, intelligent parking assistance and 360 panoramic image. Now the intelligent driving system can be very popular in new energy vehicles, most of the functions here are known or used by many people, and some of the functional principles are very easy to understand, let's talk about some of the characteristics of Volkswagen in this system.
Like a lane-keeping system, it is to keep the vehicle driving in the middle of the lane, IDWhen the vehicle deviates from the lane, the steering wheel will vibrate to alert the driver and give steering correction forceIn the intelligent lane change system, the system will judge whether the surrounding environment is safe after the driver turns the turn signal, and automatically complete the lane change at the right timeAutomatic emergency braking IDThe model can detect vehicles and pedestrians slowing down or stationary in the same direction in front of them at about 60 kilometers per hour, prompt the driver and intervene in time to brake.
The focus is on the emergency assistance system, which can monitor whether the driver is driving normally, and if an abnormality is found, it will remind the driver to take over the vehicle through a system prompt sound and a slight brake. If the driver still fails to resume driving, the system will assume that the driver is in a problem, and the vehicle will control the vehicle to gradually brake in the lane through driver assistance systems such as lane keeping and adaptive cruise control, light up the double flash, and unlock the door, while the SOS emergency call function will actively contact the call center to ensure the safety of the driver. The biggest use of this function is that if the driver really has an accident that cannot take the initiative to call for help, the system can first ensure safety and then help to call for help in time.
Augmented reality head-up display system components
When it comes to the car, the most obvious active safety configuration is the augmented reality head-up display system, also known as the AR HUD, which is displayed in the IDStandard on the 7 Vizzion, the system integrates key indication information such as navigation, cruise, lane keeping, and distance from the vehicle in front with the road, so that the driver can go straight to the key driving information by simply following the indication signs without distracting attention. With it there is actually no need for a dashboard, but idThe 7 Vizzion is still equipped with a traditional digital instrument cluster as a backup guarantee in case the HUD information is not clear when wearing polarized sunglasses.
Explosive seat belt components
Volkswagen's experts specifically mentioned the most common seat belts in the car, the function of the seat belt is to tighten the body in the event of a collision, and IDThe model is newly equipped with a tubular detonation device for the front seat belt, which is installed in the fixed position of the seat belt floor under the B-pillar on the outside of the front seat, which is triggered together with the seat belt tightening device in the event of a collision, tightening the shoulders and abdomen of the front seat occupants from two directions, allowing the occupants to be better fixed on the seat, and working with the airbag to reduce the damage caused by the collision.
Seat belts are passive safety, and passive safety has always been Volkswagen's strong point. In addition to the body with high-strength materials, for IDThe crossmembers under the seats also provide additional protection for the high-voltage battery system, and a special aluminium profile is equipped in the lower side sill of the body, which also provides side impact cushioning for the battery pack to minimize battery deformation caused by collisions. In addition, in the event of a serious collision, the airbag and battery pack detonation device will be activated after the vehicle unlocks the door, that is, the airbag will open and the battery will be de-energized. 
Negative detonator inside the battery pack
At the same time, the windows and sunroof of the vehicle are automatically closed to prevent debris from splashing into the car, but there will be a gap of 5 cm to prevent the air pressure in the car from rising instantaneously when the airbag is opened and causing damage to the occupants' eardrums. There is no need to worry about not being able to call for help after a collision, and the SOS call system is independently powered. Not only is it equipped with a number of measures to reduce the risk of collision, but it is also a rich and thoughtful protection measure in the event of a collisionThe passive safety of the model is as good as ever.
Battery module with 3D mica thermal insulation sheet
Finally, let's talk about the battery, its safety and durability are the focus of all manufacturers in the development of new energy vehicles, especially pure electric models. Volkswagen IDThe battery pack of the family adopts a "chocolate" modular design, which can flexibly adjust the number of battery modules to meet different battery life needs, and the battery pack also adopts a high-strength and precise anti-corrosion design to improve its safety. In the battery system, an independent thermal management system allows the battery to remain in normal operation at temperatures ranging from -30 to -55.
In addition, its battery management system has a thermal diffusion monitoring function, which can monitor the battery status and warn the user in time when encountering abnormal conditionsIn the event of a high-voltage short circuit, the system will actively cut off the power supply to the high-voltage systemWith comprehensive safety protection measures and effective monitoring functions, it must undergo rigorous durability and durability tests before users can boldly use it with peace of mind. Volkswagen provides users with an 8-year 160,000 km battery warranty service, and after the driving condition life test, the battery capacity retention rate is still higher than 70% after 8 years or 160,000 km.
The era of vehicle electrification has come, and the rich active safety equipment and battery safety represented by intelligent driving are highly valued by all manufacturersGO Security Lab", the structure to the principle of these functions from the detailed analysis to everyone, in these functions also into their own concept and characteristics, so that consumers of IDThe family's safety equipment is clear and assured, which also shows that Volkswagen attaches great importance to and believes in the safety performance of its products.
