According to foreign media reports, from seat belts to electronic stability control (ESC), automobile safety has existed since the birth of the first automobile in the 19th century, and the development history of automobile safety is as long as that of automobile. Xiaobian specially sorted out the development track of automobile safety (systems and equipment) for users’ reference.
Early braking system
As early as the 19th century, the braking system has existed in the earliest cars. This kind of equipment has been continuously improved and changed, from the early drum brake to the current disc brake.
Various safety equipment
By the 1930s, mass-produced models were equipped with a variety of safety equipment such as laminated glass windshields. In 1934, the industry conducted the first obstacle collision test. In 1936, Hudson terraplane invented the backup braking system. In 1937, Buick launched its first turn signal lamp.
In 1941, Tucker, an American car company, built the world’s first pedal dashboard. In 1949, several Swedish car companies developed proto seat belts, which looked like a safety cage. In 1958, Scandinavians made the safety belt standard and was responsible for developing the three-point seat belt.
Evolution of airbag
In order to prevent casualties in the event of an accident, although the first electronic sensor for starting the airbag was born as early as 1968, the driver’s airbag was not included in low-end vehicles until the 1990s, while side impact airbags appeared in the late 1990s. It was not until 1998 that airbag became a necessary safety equipment for all vehicles.
Anti locking braking systems
Today’s anti lock braking system was originally developed for aircraft to prevent the landing gear from falling normally after landing.
The first vehicle anti lock braking system was adopted in the 1970s and became the standard system of vehicles in the late 1980s. The system can detect the speed of a single wheel of the vehicle. If the wheel speed is too slow, hydraulic fluid will be released. The steering control function can be provided when the vehicle performs braking operation on wet road surface.
Electronic stability control (ESC)
The electronic stability control system was first launched in 1983, and then became the standard system of vehicles in the 1990s. When the loss of traction is detected, the system can help the driver deal with the steering operation and apply braking force to each wheel, so as to improve driving controllability and vehicle stability.
Rear view camera
This technology was first introduced and configured into the Buick Centurion concept model in 1956. The latter has a rear mounted television camera, which can send images to the TV screen in the instrument panel when the rear-view mirror is in place. In 1991, the rear view camera was used in mass production models, and now it has become the standard equipment of many vehicles.
Automatic driving safety function
The first automatic driving braking function was born in 2008. It can sense static traffic, warn the driver and take braking action. In the past 8 years, many new active safety and driving assistance functions have been born in the industry.
Lane keeping assist system capable of preventing collision
Functions such as lane keeping assist system can send visual and audio warnings to drivers to help drivers drive in the original lane. After the lane departure warning system finds that the vehicle deviates from the established lane and the vehicle does not give warning, the system will remind the driver through clear visual and audio warning.
The driver attention warning system continuously monitors the driver’s operation, analyzes the driver through the steering angle, steering torque and the position of the vehicle in the lane, and gives warnings when necessary.
With the continuous development of Internet and automatic driving technology, new driving safety systems are bound to emerge in the future. Let’s wait and see!
