Of course, this is not to encourage people to buy a beggar version, but to hope that you can understand: what is the most important when buying a car? Of course it's safe. So you have to be careful when choosing a car, because the leather seat won't save your life at the critical moment, and some practical safety devices can actually protect you from fatal damage. Among them, security configuration is divided into two main categories: Active and passive safety. As the name implies, the role of active safety allocation is to actively prevent accidents, Electronic systems such as ABS, BD, ESP, TPMS; The role of passive safety configuration is to protect the occupants of the vehicle to the maximum extent after the accident, and to minimize the losses, Such as seat belts, airbags, children's safety seats, children's safety door locks, etc.
With the development of science and technology, the car safety configuration is already dazzling, but consumers must find out which safety configuration is necessary and which is optional. Although in theory, the more secure the better, it is undeniable that as the configuration increases, so the cost of a car will increase. Therefore, today I will explain for everyone, exactly which safety configuration is necessary, in order to give you a reference when purchasing a vehicle.
Passive security configuration
First of all, talk about passive security configuration. Generally speaking, seat belts, airbags, child safety seats, children's safety door locks, etc., are essential in passenger cars. This is the most basic and most effective vehicle safety configuration; most passenger cars have been popularized. Seat belts are considered life belts, and the use of seat belt buckles is tantamount to playing with one's own life. The safety belt and airbag constitute a complete safety system, which can protect the personal safety of the steward as much as possible in the course of the vehicle collision. In addition to the usual airbags around the main co-pilot, it's also important to focus on the side airbags. Because the most vulnerable part of the collision is the side of the vehicle. Statistical data show that side impact has become one of the main causes of high vehicle traffic mortality. Therefore, if conditions are available, the side airbags should be considered as far as possible in the purchase of vehicles.
Child seat is a kind of device that is specially designed to protect infants and children. At present, there are many kinds of child seats. Consumers can take them into consideration according to their age and weight. Especially for children aged 0-6, they must take the children’s seat. European and American countries have strict definitions of child safety seats: it can be fixed to a motor vehicle. A child safety protection system consisting of seatbelt assemblies or flexible components with isofix interfaces, regulators, accessories, etc. In dangerous situations, such as car collisions, it can reduce the impact pressure on children and limit their body movement, thus reducing their injuries. Child safety locks are also designed to prevent accidents when children suddenly open their doors.
Active security configurations
As for active security configurations, there are more types of such configurations, but taken together, the necessary configurations include: ABS braking and anti-lock braking system, ESP/DSC body stabilization system, TPMS tire pressure detection system, DRL reversing image system, DRL daytime traffic lights, etc., while others such as AWS anti-collision warning system, lane departure warning system (LDW), Adaptive Cruise (ACC), Lane maintenance Auxiliary system (LKA), parallel line auxiliary system, adaptive headlights, automatic parking system, fatigue driving warning system, and pedestrian monitoring active braking system, etc. Of course, if you pursue perfection and have the strength to buy a car, more configurations, more better.
Among the necessary configurations listed, the ABS braking and anti-lock braking system has a long history, and most of the models are now standard. When the vehicle brakes with great strength, it can prevent the four wheels from being clung to, reduce the risk of vehicle runaway or sideslip, tail-flick, and reduce the occurrence of accidents. The EBD electronic braking force distribution system and the EBA/BAS brake auxiliary system are actually the auxiliary functions of abs, which can improve the efficiency of ABS, shorten the braking distance and improve the braking force.
The ESP body stability control system can judge the driving state of the vehicle by the sensor when the vehicle understeer or oversteer, and brake the corresponding wheel, and adjust the track direction to keep the vehicle stable. Therefore, ESP can not only improve the limit of vehicle control to a certain extent, but also is an indispensable configuration in the current vehicle purchase scheme.
The TPMS tire pressure detection system is important because no matter how noble the car is, it has four tires in direct contact with the ground, and if a tire has a problem, such as a flat tire, the consequences are serious. The reason why the tire burst is mostly related to the pressure of the tire. It has been proved that when the tire pressure is lower than the standard 75%, the probability of the tire burst will increase threefold, especially when driving at high speed once the tire burst, the consequences will be unthinkable.
DRL reversing image system is a very practical security configuration, especially for daily reversing. It is very useful. Although this configuration is not considered a safe one for many people, there are not a few casualties caused by reversing traffic every year. Reverse image can effectively eliminate the rear blind area, very practical. Of course, even if the new car does not have such a configuration, late installation is not expensive.
DRL daytime driving lights can still be used as a reminder to the surrounding vehicles without turning on the lights, and avoid the development of accidents. In addition to the safety effect, the DRL daytime driving lights are also regarded as a symbol of the recognition of each brand.
Some non-essential security configurations
In addition, there are some non-essential security configurations that are worth noting, and they tend to be found only in high-end models. For example, the AWS anti-collision warning system can effectively prevent accidents, and can provide the driver with timely sound and visual alarm before the danger occurs. Even when approaching the pedestrian, the vehicle can automatically slow down the brake. The LDW lane deviation warning system can identify the driver when the vehicle deviates from the original lane due to fatigue and other unconscious states, and can alert the driver through steering wheel vibration, so as to gain more reaction time for the driver. This greatly reduces the collision accidents caused by lane deviation when driving fatigue.
ACC adaptive cruise is an intelligent automatic control system, which continuously scans the front road of the vehicle by the distance sensor (radar) installed in the front of the vehicle, while collecting the speed signal by the wheel speed sensor. It realizes automatic cruising while maintaining a safe distance from the front car; The LKS lane retention auxiliary system can not only give a warning when the vehicle deviates from the lane, but also take the initiative to turn around, so that the vehicle will remain in the original lane. Parallel-line auxiliary system is blind area detection, reminding drivers of the situation around the blind area, is a good function. The adaptive headlamp is a kind of front lighting system which can automatically change two or more light types to adapt to the change of vehicle driving conditions, especially plays a great role in driving safety at night.
The safety configuration is various. Seat belts, airbags, and ESP are all necessary to consider when buying a car. No matter how rich the security configuration is, it can only serve as a protection, not as a panacea to ensure the absolute safety of drivers. Only by paying attention to safety and developing good driving habits can you avoid accidents and minimize harm to yourself and others.
