Automobile traffic accidents are a complex social problem, people, cars, the environment, and many factors, of which people are the main factors.

According to big data statistics, automobile traffic accidents in 88% of the reasons out of the driver, usually people are most likely to make three kinds of mistakes:

1, ? Insufficient knowledge of the safety of the vehicle, do not pay attention to the situation ahead.

2,? Thinking the other person will avoid.

3, ? Improper driving operation, mistakenly stepping on the brake or power pedal.

Automobile safety is not only a technical problem, but also an important social problem, automobile safety includes active safety technology and safety technology. Now the popular active safety technology: Germany's electronic body stability program ESP, Japan's Toyota body stability VSC, tire pressure monitoring, lane departure assistance, infrared night vision, collision safety.

Passive safety technologies: airbags, automobile rollover protection system, battery line cut-off device. Safety systems that minimize damage after an accident.

"Old Willow Talks Cars" introduces you to the main types of safety technology fitted to vehicles today.

Cars didn't have safety systems at the start of their life in 1886 until Volvo developed the three-point seatbelt in 1959, and in 1970 Volvo started fitting child safety seats in cars.

The concept of crash cushioning and energy absorption was first introduced in 1966, and is now often used by Toyota to publicize its safety energy-absorbing body.

ABS was first used in the automobile industry in the 1950s, and ESP was invented in the early 1990s, with Mercedes-Benz being the first sedan to be equipped with ESP.

Active safety technology:

ABS to EBD

ABS was the earliest active safety system, braking the vehicle without loss of steering control, preventing skidding and tailgating. Play drifting to turn off the ABS on the vehicle. and EBD electronic brake force distribution in the car braking according to the wheel speed and vehicle attitude with ABS, to improve braking stability. EBD can be in the moment of braking, respectively, four tires speed, sensing, and high-speed calculations, and issued a directive, to adjust the speed of the four wheels, to ensure the stability of the body. EBD is an upgraded version of ABS.

ASR traction control is an upgraded version of brake safety technology, adding control of power output to ensure vehicle stability during starting, acceleration and steering.

EDS electronic differential lock belongs to the four-wheel-drive vehicles must have a good tool, when a certain side of the wheel left slip, EDS will lock this wheel, so as to improve the other side of the drive.

ESP body stability system is their comprehensive upgraded version of the integrated their technology, through the various sensors on the vehicle to analyze and calculate, including wheel speed sensors, direction sensors, brake accelerator pedal travel sensors, side-slip sensors, lateral acceleration sensors data acquisition, braking, direction, power computer intervention, control body posture. This system is called ESP on Volkswagen, DSC on BMW, VSC on Toyota, and VSA on Honda.

Tire pressure monitoring, lane departure assist, and high-beam assist have become popular in recent years, but are mostly installed on higher-end versions of vehicles. Night vision assist is mostly installed in luxury vehicles, using thermal imaging cameras to capture people or animals, his perception area is farther than the lights, is a good helper for evening driving. This system manufacturers will do the instructions for use, but it is only an auxiliary system, only help, the driver is fully responsible for the operation.

Passive safety technology:

Besides seat belts and airbags, the high-strength frame is the most important part of the passive safety system. Vehicle skeleton body is also used car inspection of the four beams and six columns, the Japanese car skeleton can be identified with the naked eye welding points, but the Volkswagen system is not, which has been rumored to be the Volkswagen system is stronger than the Japanese system, Volkswagen is using a high-strength laser-welded body, laser welding was first used in the welding of military tanks body, which can increase the strength of the body, reduce the weight of the body, the German BMW first laser welding, and then the Volkswagen The basic popularization of laser welded body. The domestic Haima 3 is also used for laser welding body.

Different car lines have their own different safety technology body, Toyota is GOA energy-absorbing body, in the event of a crash in a self-sacrificing way to cut off the impact, the maximum possible protection of the cockpit. GOA body requirements are a stamping success, no welding structure, the domestic production and the Toyota lineup of cars with obvious welding points.

Honda's G-CON body, Mazda 3H body, Volvo large grade steel body, Audi ASF body, etc., each has its own advantages.

Passive safety technologies also include safety steering columns, sag-resistant seats, safety plastic fuel tanks, active head restraints, side-door crash bars, and pedestrian protection systems.

COF Collapsible Brake Pedal Working Principle:

When a frontal collision occurs in an automobile, the driver takes the initiative to brake at the same time, and if the pressure on the brake pedal reaches a certain critical value as determined by the computer, the brake pedal will automatically come off or break, thus minimizing the impact on the driver's right foot and avoiding serious trauma to the driver.

NCAP new car test protocol

New car test protocols in all countries around the world, China is called C-NCAP, but in recent years C-NCAP suffers from dirt, five stars in the country to Europe is not recognized. Because NCAP is the respective country's own standards, CNCAP is China Automotive Technology Research Center, under the State-owned Assets Supervision and Administration Commission of the State Council, the results have authority.

Recently, there has been a flurry of evaluation reports from CNCAP, and both of them have basically the same approach to vehicle testing. In the insurance research is subordinate to the insurance industry association company, just in the insurance industry evaluation results, the insurance industry association belongs to the civil organization, does not have the authority, and there is no right to judicial interpretation. So only as a reference.

Road traffic safety is composed of three elements: people, cars and the environment, but the core is still people, "Lao Liu said the car" that the key to the 21st century is to solve the problem of people, so the future is unmanned technology world.
