What is the anti-lock braking system ABS on cars?
ABS is an active anti-lock braking system common on most car models today.
This is a system with a safe, active mechanism, with the effect of reducing speed, stopping and parking the car when necessary.
Accordingly, when the car brakes suddenly on a slippery road, the phenomenon of wheel locking easily occurs, which can cause the wheel to slide on the road when braking, causing danger to the people in the car. The anti-lock braking system ABS was born to solve this problem.
Structure
The anti-lock braking system (ABS) on a car consists of components including: speed sensor, hydraulic valve and control system.
The speed sensor is the part that helps the ABS system detect whether the wheels are locked or not. These speed sensors are placed on each wheel or differential.
The hydraulic valve is the valve that controls the brake pads at each wheel.
Accordingly, the hydraulic valve will be in 3 basic positions including: open valve, which means that when the driver applies a certain amount of force, the brake pressure will create an equivalent force transmitted directly to the wheel; Lock valve, which means the brake pressure received is more than the pressure the driver applies to the brake; Release valve, which means the brake pressure received is less than the force the driver applies to the brake.
The computer - control system will collect information and data from speed sensors, calculate and make appropriate adjustments to the optimal brake pressure for each wheel.
Therefore, when the car is equipped with an anti-lock braking system (ABS), it will be especially effective when braking on slippery roads or when braking suddenly, ensuring the stability of the car during braking, giving the driver more time to handle the problem and protecting the safety of all passengers in the car.
History of ABS braking system development
In the early days, that is, around 1949, the ABS anti-lock braking system was only available on commercial aircraft. At this time, the structure of the ABS anti-lock braking system was quite cumbersome and not yet agile. By 1969, when electronic technology developed, this was also the time when the ABS braking system was applied on cars.
Then, since the 70s of the 20th century, many car manufacturers in the world have researched and applied the ABS anti-lock braking system to their products.
Japanese car manufacturer Toyota began using the ABS anti-lock braking system on its vehicles in 1971 but it was not completed until the 1980s.
In Germany, after Mercedes Benz and Bosch announced the results of their joint research for the first time in August 1978, the ABS anti-lock braking system was officially equipped on the Mercedes-Benz S-Class sedan of the W116 generation a few months later. By 1981, the ABS anti-lock braking system was present on all of the company's commercial vehicles.
In the 90s, the ABS anti-lock braking system became standard equipment when it came to safety features on every Mercedes car.
To date, to ensure user safety, most car models today are equipped with this feature.
