When we evaluate a car product, we usually divide it into two parts: "visible" and "invisible".

The "visible" parts are easy to understand, such as appearance, interior, space and configuration, which can be intuitively experienced. The "invisible" parts, such as driving quality and safety, especially safety, are not very good. Some people are used to putting safety in the "visible", thinking that the thicker the steel plate, the better the safety performance of the vehicle.

Even this concept is used by some dealers with ulterior motives, taking the so-called smashing means to attract people's attention. "Pi Er Bo" has also become the main reason why Japanese cars are concentrated in diss.

In fact, the safety performance of a car needs to be considered in many aspects. The thickness of automobile steel plate is only one part of it, and it can not even be said to be the main factor. If we want to systematically discuss all aspects of automobile safety from the root, we should consider the human factors, active safety factors and passive safety factors comprehensively. As long as these three aspects are up to the standard, then this car product can be regarded as a real sense of safety standards.

human factor

In fact, it is best to understand that a car is just a vehicle. The driver's subjective consciousness and driving skills determine whether the vehicle can always drive from the starting point to the destination in a healthy and good way.

From the driver's point of view, to ensure the safety of car driving should start from the following aspects. First of all, the inspection must be in place. Vehicle safety inspection is a work that is often ignored for drivers. Many drivers will not pay attention to the condition of the vehicle before driving, and will not pay attention to the situation of the vehicle until there is a fault in the process of driving, which also leads to the increase of accidents in the process of driving.

Second, it's important to control the car speed. One of the most important factors affecting driving safety is the speed, which needs to be controlled to ensure the stability of the vehicle. However, many drivers do not pay attention to the speed control, which leads to frequent traffic accidents. Many novices are not familiar with the speed of different road sections, thus causing traffic safety accidents. There are also some drivers who have a long driving experience, and because they know too much about the vehicle, they don't pay much attention to the speed control. Whether it is too fast or too slow, it will lead to accidents.

Finally, correct bad driving habits in time. Driving is a habit, and some drivers' habits are very bad, so it increases the risk of driving. For example, some people don't like to fasten their seat belts when driving, which makes their life safety not easy to be guaranteed, and some relatively minor accidents can also cause serious threats to their lives. In addition, whether the driving distance is safe or not, it is necessary to maintain a safe distance in the process of driving to make driving safe. Some drivers who follow the car too close are very prone to accidents.

Active safety technology

The above three points are all about how to ensure the safety of the vehicle from the driver's point of view. If we have passed the test in driving technology and subjective vigilance as drivers, then the next step is to test the safety attributes of the vehicle itself. When manufacturers design, they will make overall planning from two aspects: active safety and passive safety.

The so-called vehicle active safety, in fact, is all kinds of functions related to driving safety given by manufacturers for their products, in order to avoid the occurrence of traffic accidents. With the development of science and technology, there are more and more active safety configurations on vehicles.

Let's take Volvo, which is well-known as a leader in vehicle safety. The soul configuration of Volvo's products about safety is the continuously evolving Volvo citysafety urban safety system, which was born in 2008. For the first time, this system really brings automobile safety into the era of active safety. At present, according to the data of Volvo cars, the new generation of Volvo XC90 equipped with citysafety urban safety system has set a record of "zero casualties", and the incidence of rear end accidents has also decreased significantly after using this system.

The system can detect and identify vehicles, pedestrians, riders and large animals, and can also be implemented in low light conditions at dawn or dusk. When a danger is found, the system will give warning, and active braking or power steering will be provided to reduce collision or loss. Typical active security configuration.

Although the vehicles of other manufacturers do not have citysafety urban safety system, they also develop their own active safety functions. For example, Toyota's active safety system TSS has been popularized in the new tnga architecture. Honda's "Honda sensing safety super sense" active safety system has also been applied to all kinds of its main sales models. Independent brands such as Geely, great wall, Chang'an and other first-line brands have also developed active safety systems.

All of the above active safety systems, in addition to anti lock braking system (ABS), panoramic look system, tire pressure monitoring system (TPMS) and other very common functions. At present, the latest development trend of active safety system is to combine with high-level automatic driving technology. For example, lane departure warning system (LDWS) is an important part of automatic driving technology above L2 level.

Lane departure warning system can be used to deviate from the vehicle without turning on the steering light
