The anti-lock braking system (ABS) is an essential car safety feature, introduced in the late 1970s. The system helps to prevent wheels from locking up during braking, enabling the driver to maintain steering control and avoid skidding. The anti-lock braking system was a significant breakthrough in car safety features and has since become standard in most modern cars. Here we will trace the anti-lock braking system history from its inception to its current state.
What is an Anti-lock Braking System?
The anti-lock braking system also referred to as the anti-lock brakes or ABS prevents wheels from locking up during sudden braking. ABS helps the driver maintain steering control and reduces the stopping distance, making it easier to stop the vehicle safely in an emergency. It uses sensors to monitor the speed of each car wheel and automatically adjusts the brake pressure to prevent skidding and loss of control.
History of ABS Brakes
The history of ABS brakes has its roots in aircraft safety systems. It wasn’t until the late 1970s, this technology was introduced in cars. Since then, the anti-lock braking system has undergone significant improvements and refined into a crucial, modern car safety feature. Let’s dive into the anti-lock brakes history and discover its evolution over time.
The Early ABS Technology
The idea of ABS can be traced back to the early 1900s when aircraft designers developed similar systems to prevent skidding on runways. Gabriel Voisin, a French pioneer, experimented with modulating the hydraulic braking pressure of his plane’s brakes to prevent tyre slippage that could harm the aircraft. The result was one of the early prototypes of the anti-lock braking system.
Developments in ABS
Before ABS, the drivers used a technique named, ‘threshold braking’ to avoid skidding in emergencies. This technique required the driver to brake just below the point where the wheels would lock up.
ABS was limited to use in aircraft only for a few decades, before being used on motorcycles in the 1950s. Here, drivers faced significant risks of sliding and losing traction, which is why the anti-lock brakes were invented. The anti-lock brakes significantly raised the bar on safety.
Somewhere between the 1950s and 1960s, several manufacturers started experimenting with anti-lock brakes. More types of car sensors and quicker data processing were needed for ABS to effectively identify the acceleration and deceleration of a car’s wheels on uneven surfaces and during turns.
Mercedes-Benz was the first to start working on the electro-hydraulic brake control system. In 1966, they teamed up with the business that eventually became Bosch. This collaboration led to the debut of a moderately successful analogue-electronic system in 1970. It was the defining moment in anti-lock braking system history as the system was being modified for automobiles.
The Modern ABS System
Other auto manufacturers followed the course set by Mercedes. In the early 1970s, Ford and General Motors added rear-wheel ABS to their premium models as an exclusive add-on. However, rear-wheel ABS only provided minor advantages because a car’s front wheels are where the majority of its braking and steering force is generated. Nissan and Toyota were not lagging either, and they worked on developing ABS as well.
Chrysler teamed up with the Bendix Corporation to develop the first four-wheel electronic-controlled ABS, named ‘Sure Brake’, and added it to their Imperial lineup in 1971. However, the marketing for Sure Brake fell flat a while later and it disappeared in the mid-1970s.
Whereas, Mercedes continued to work on the concept of a four-wheel, multi-channel ABS with a digital controller. This led to the debut of the second-generation ‘Anti-Bloc’ system in 1978. It was similar to the modern ABS.
In the history of the anti-lock braking system, Lincoln became one of the first automakers to provide four-wheel ABS as a standard system in 1993. Since then, every leading automaker has incorporated various types of anti-lock braking systems into their vehicles, initially as an option and later as a standard.
Summing up the anti-lock braking system history, the early ABS were relatively simple and had limited capabilities. They could only prevent the wheels from locking up during hard braking, but they didn’t provide any additional benefits. However, over the years, the technology has improved, and newer ABS system now offer a range of features, such as traction control, stability control, and emergency brake assist. This system has a profound impact on road safety and automotive technology.
That said, if you are still driving an old car without modern car safety features, you should consider switching to a modern car. Browse these used cars for sale in the UAE with high-tech features and buy yourself a safer ride.
