ABS can also be called as Anti-lock braking System. It is used to avoid skidding of vehicles while applying brakes so that the driver can steer the vehicle in desired direction. ABS works by ensuring that no wheel in the vehicle is looked up. It works on the principle of threshold braking and cadence braking. When the brake is applied with great amount of pressure over brakes when somethings interfere in path of the vehicle, the ABS will control the rate at which the individual wheels decelerate instead of stopping the wheels to rotate at once. It is done by controlling the line pressure applied to the foundation brakes of each wheel thus reducing the friction between the wheel and the road. It does it by the help of speed sensors to determine if one or more wheels are trying to lock up by limiting the braking over these vehicles.
There are many studies which have proven that ABS have reduced the amount of fatal accidents in many countries. It has reduced more than 50% of the accidents due to skidding of vehicles while applying brakes.
Components of ABS:
There are 4 major components for ABS, they are
Speed Sensors are used to find the deceleration and acceleration of the wheel. It uses Hall Effect sensors and Magnetic coil to determine the speed of the vehicle by calculating the voltage difference in coil generated by Magnetic flux.
Valves:
The valve will safe guard the wheel breaking system to get applied with full force i.e when the driver presses the brakes harder. It will increase or decrease the pressure over brakes by getting signals from the controller.
Pump:
The pump in the ABS is used to restore the pressure to the hydraulic brakes after the valves have released it.
Controller:
Controller is one where everything in ABS is co ordinated.This is where speed sensors response are detected and accordingly valve and Pump is allowed to work. It is the ECU(Electronic control unit) type unit .
Use of ABS:
As the ABS prevents the wheels to lock up , unavoidable skidding is avoided. During rainy seasons due to slick roads the tires without friction will keep on spinning resulting in accident, such incidents can be reduced to a greater extend by using ABS brakes. Even though the drivers are well versed or professional it becomes very difficult for them to handle such situations.
