How do you describe the safety of a vehicle? What is the safety of the car?

1. Visuality. Refers to the degree to which roads, other vehicles, traffic signals and instruments can be seen and seen clearly.

2. Driving operability. It refers to the degree of convenience and flexibility of driving operation.

3. Braking efficiency. Refers to the ability of a car to brake at high speeds. Not only should it be able to slow down and stop, but it should also not deviate, sideslide, flick, etc.

4. Structural energy absorption. The car should have a deformable and energy-absorbing nose structure, as well as a sufficiently rigid and shape-stable cockpit. The stiffness of the head of the car is usually designed to be smaller than the stiffness of the cockpit, so that the head absorbs as much as possible the impact energy generated during the collision.

Safety performance. The development of the automobile industry is changing with each passing day, safety has gradually become the primary factor for the majority of car owners to consider when buying a car, even if due to the constraints of practical factors such as funds, the subconscious still lists safety as the focus, new cars emerge in endlessly, and safety measures are frequent, but for second-hand cars, their safety is often ignored.

Over time, I have walked into a misunderstanding, thinking that second-hand cars are cheap, but in fact, safety is the most important concern for second-hand cars. Due to the uncertainties of second-hand cars, the asymmetry of information, etc., there are great safety risks in second-hand cars. Therefore, there is a trade-off between economy and safety.

What are the aspects of car safety? Teach you 5 trivia to maintain your car.

1.The safety performance of a car refers to the performance of avoiding accidents and ensuring the safety of pedestrians and passengers. Xiangyou is generally divided into active safety, passive safety, post-accident safety and ecological safety.

In road traffic accidents, the safety performance of the car itself is also a factor that cannot be ignored. Good car safety can often avoid accidents or reduce the degree.

2.Active safety of automobiles, also known as active safety and security, mainly refers to the performance of automobiles in preventing or reducing road traffic accidents. This includes visibility, driving maneuverability and braking efficiency. In addition, it includes reducing driver fatigue and pedestrian safety.

3.Passive safety, also known as passive safety, refers to the ability to reduce passengers** in the event of an accident. Including: structural energy absorption, internal softening, safety protection devices, safety glass, etc.

4.Post-accident safety refers to the performance of a car that reduces the consequences of an accident. Including whether the consequences of the accident can be eliminated quickly and Nahui can avoid new accidents.

5.Ecological safety refers to the impact of engine exhaust pollution, automobile driving noise, and electromagnetic waves on the environment.

Vehicle safety performance refers to the performance of avoiding accidents and ensuring the safety of pedestrians and passengers during driving, which is generally divided into active safety, passive safety, post-accident safety and bionuclear safety. In road traffic accidents, the safety performance of the car itself is also a factor that cannot be ignored. Good car safety can often avoid re-erector accidents or reduce the degree of personnel**.

Automobile active safety, also known as active safety, mainly refers to the performance of automobiles to prevent or reduce road traffic accidents. These include: visibility, driving maneuverability and braking efficiency. In addition, it includes reducing driver fatigue and pedestrian safety.

Passive safety, also known as passive safety, refers to the ability to reduce passengers in the event of an accident. It mainly includes: structural energy absorption, internal softening, safety guards and safety glass, etc.

Post-accident safety refers to the performance of a car that reduces the consequences of an accident. Including whether the consequences of the accident can be quickly eliminated and whether new accidents can be avoided.

Ecological safety refers to the impact of engine exhaust pollution, vehicle driving noise and electromagnetic waves on the environment.

When buying a new car, people will consider a lot of factors, such as:**, brand, model, fuel efficiency, safety, comfort, and so on. Different people may have different considerations, so the most important factors will also vary from person to person.

I believe that the most important factor is safety, because it is related to the safety of myself and my passengers.

The safety performance of automobiles is generally divided into active safety, passive safety, post-accident safety and ecological safety. Active safety refers to the performance of the car itself to prevent or reduce road traffic accidents, such as: anti-lock braking system, car crash stability control system, adaptive cruise control system, etc.

Passive safety refers to the safety performance of the car to protect the driver and passengers in the event of a collision, such as airbags, seat belt pretensioners, etc. Post-accident safety refers to the safety performance of a car to protect the driver and passengers after a collision, such as:

Emergency power cut-off, automatic ventilation, etc. Ecological safety refers to the impact of a car on the environment.

Therefore, all of the above factors need to be paid attention to.

As for how to judge the safety of a car, I will give a few examples. First, the emergency avoidance performance of the vehicle. At present, there is nothing more important than safety, the emergency avoidance function of the vehicle is of course the most important thing for the safety of the car, this is the first element of the safety of the car, the first aspect is whether the braking performance is good, and the other is whether the operation performance is good in the case of emergency braking, the braking distance in addition to the size of the brake disc, and the performance of the tire is also very important.

Many people tend to ignore this when buying a car, protect the protection of this crack, maintenance to maintenance, and do not pay attention to these four tires, in addition to looking at this also depends on the car's emergency line change and handling performance, these two properties represent the ultimate performance of the car, she belongs to the car's stability control system, so the safety of the car is also crucial.

Second, crash performance test. Commenting on whether there is a collision on the front side of the car or a small area, the collision should be based on the foreign collision passing results, because the foreign collision results are the most stringent. This will help us to choose a car with better crash performance.

Because the crash lift lead test is the best way to measure the safety performance of a vehicle.

Third, the car's anti-rear-end protection. The protection of the people on the rear-end collision in the current car mainly depends on the seat and the headrest, and the headrest on the car is used to protect the whiplash caused by the rear-end collision.

Fourth, the configuration of active and passive safety. Many vehicles now have advanced active and passive safety configurations. For example, airbag curtains, etc., these not only allow the people in the car to survive the accident, because these can replace the driver's own judgment to a certain extent, and greatly reduce the personal injury caused by the accident.

Fifth, blind spots. No matter how old the driver is, he can't avoid the blind spot of the vehicle, and can only rely on experience to judge, so there are two considerations for the blind spot of the vehicle, and he is busy with the smallest things as much as possible, but also as good as possible. In this way, traffic accidents can be greatly reduced.

You can look at some of the configuration and workmanship of this car, these two aspects can determine the impact resistance and stability of a car, so that safety can be better measured.

When we buy a car hand mill, we must check the A-pillar of the car's nuclear Zen in advance, and then we must look at the crash test of this car, which can determine whether the car is safe or not.

The safety of a car is measured by checking its impact resistance through simulation experiments.
