ABS System Adrian Skowron #5

So what is ABS?

So, ABS stands for Anti-lock Braking System and it was designed to help the driver maintain some steering ability and avoid skidding while braking. The Anti-lock Braking System was first introduced in the mid -1980s. In today’s world we can easily say that it became a ”standard" equipment in every single car there is. The Anti-lock Braking System helps with stability and allows steering while maximizing braking. As well as that, it allows the diver to maintain control of the vehicle while is skids. Since four-wheel ABS prevents all wheels from skidding, it allows you to steer the vehicle and still maintain braking.

How it works?

ABS uses wheel speed sensors to determine if one or more wheels are trying to lock up during braking.  If a wheel tries to lock up while it skids, a series of hydraulic valves limit or reduce the braking on that wheel. This helps to prevent skidding and allows the driver to maintain steering control and slow down the vehicle. It also has the ability to build the pressure back up via the hydraulic motor. The system reacts remarkably quickly, and compared wheel speeds many times a second. ABS systems can work on just the front wheels or all four but it depends on what car you own. As I mentioned above, ABS is standard in today’s cars as it will allow you to manoeuvre from dangerous and unexpected road situations.[2]
