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, click to see 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 transportation，Drive on the road，Safety risks at any time。One meter per car every extra，One more second，It will produce irreparable damage risks。And these risks are determined by the factors of the amount，For example, the technical level of the driver，driving habit，Car knowledge，Driving 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 long as there is an interference with artificial factors，There is a possibility of safety risks at any time。From the data of the car accident in our daily life，In a car accident，Most 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 how thick to see the steel plate，How heavy is the body; more importantly, to effectively control the effects of this artificial factors，Small control，The less dangerous occurred，Safety coefficient will become larger。

2. Active safety configuration.

Back to the car itself，The so -called car active safety，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，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 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 danger，Putting the prevention of collision always placed in one bit。

3. Passive safety configuration.

Passive safety configuration, as the name implies, is when the danger occurs in collision，Device provided by the driver and ride，seabet loginto reduce damage，Reduce the 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，The body can effectively absorb the energy generated by collisions，and dispersed these energy into the structure parts of the body，reduces the deformation of the cab to minimum degree，To protect the safety of the person in the car。And，When the car is driving over 50 kilometers, a collision accident occurs every hour，What determines the safety of the car 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 structural 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 car surface 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，This is more harmful to the personnel in the car，and because the steel plate is too thick，It will also increase body weight and fuel consumption。

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