Many people think，The thicker the steel plate of the car，The heavier the car，The more safer the car is，Especially when many people go to the car at 4S to click the car，I like to knock on the surface steel plate of the car，Listening to the sound，Feeling the thickness of the steel plate is not thick，To judge whether the quality of the car is good，An Inspermail。In fact, there are great misunderstandings and misunderstandings here，Because this conclusion is incomplete，It is also unscientific，Let me make a detailed analysis below。

Total summary，Measure whether a car is unsafe，I think there are the following three standard factors。One is human factor; the second car active safety configuration; the latter is the passive safety configuration of the car。

a. Human factors.

We all know，Cars as a big weight，Fast means of transportation，Driving on the road，Safety risks at any time。One meter per car for a car，One more second，All produce irreparable damage risks。And these risks are determined by the factors of the amount，For example, the driver's technical level，driving habit，Car knowledge，Drive status (drunk driving drunk，fatigue driving)，Traffic safety awareness，Interference of staff on the car，Pedestrian safety awareness and other factors，It is possible to cause car traffic safety risks。

Even if your car is safe，Good quality，As Seabetlong as there is an interference with artificial factors，There is a possibility of safety risks at any time。Judging from the car accident data in our daily life，In a car accident，Most of the accidents are mostly caused by human factors; it can be seen here，The car is unsafe in the end，In fact, the first thing to consider is not to see how thick the steel plate is，How heavy is the body; more importantly, to effectively control the effects of this artificial factors，Small control，The less dangerous, the less dangerous，The larger the safety factor will be larger。

2. Active safety configuration.

Back to the car itself，The so -called car active safety，It is the danger of preventing accidents in the car，Avoid accidents。Mainly the braking performance of the car，Driving stability，Dynamic，Conditions such as manipulation and information feedback。So which are active safety configurations，I will popularize it for everyone，

1.ABS+EBD --- Anti-hugging braking system+electronic power distribution system。Many models are basically standard

2.ESP --- body electronic stabilization system。Improve car acceleration，Turn for steering，Stability during braking，Reduce the risk of sideways

3.HAC --- Auxiliary system.

4.ACC --- Cruise control system.。

5.AWS --- collision warning system.

6.TPMS --- Tire pressure monitoring system.

above lists the main more common active safety configurations，There are also many electronic auxiliary systems that have not been listed，It should be said that they are all active safety configurations，The final purpose is to avoid the occurrence of danger，Putting the prevention of collision always placed in one bit。

3. Passive safety configuration.

Passive safety configuration, as the name implies, is when it is in danger such as collision，Device provided by the driver and ride provides protection，to reduce damage，Reduce seabet loginthe occurrence of collision accidents，Maximum saving life。The main configuration has a body structure，Bag Bag，seat belt，shrinkable steering wheel，Internal and external rearview mirrors, etc.。

Among them, the body structure is the most important passive safety configuration，When a car collides with a collision，The body can effectively absorb the energy generated by collision，and dispersed these energy into various structures of the body，reduces the deformation of the cab to minimum degree，To protect the safety of personnel in the car。And，When the car is driving over 50 kilometers, a collision accident occurs every hour，Determine whether the car is safe or not is the body structure，Not the steel plate thickness of the car coverage。

It is not the thickness of the steel plate that determines the stiffness and strength of the body，but the structure parts and inner plates inside the body; what we usually call car steel plate thick，All are the thickness of the steel plate on the surface of the car that we can see，and these surface steel plates are just the cover of the car，That is the outer board，It has limited contribution to the rigidity and strength of the body。

The thicker the steel plate on the outer plate，The greater the rigidity of its rigidity，When a collision occurs at low speeds，The rigid body is not easy to deform，Vehicle loss is relatively small; when driving at high speed，Due to the rigidity of the outer board，The front part of the body is not easy to deform and causes the overall squeeze to the cab，So the damage to the personnel in the car is relatively large，and because the steel plate is too thick，It will also increase body weight and fuel consumption。

To sum up，I think it's unsafe to evaluate a car security，At least the standards of the above three major aspects should be measured，and car steel plates as covered parts on the surface of the seabet mycar，It is just a structural component in the passive safety configuration，and not the most important safety parts。So say，The thicker the steel plate, the more safer it is. This is not comprehensive，It is also unscientific。The above is only a personal point of view，Welcome everyone to exchange and share learning，Thank you!
