IN A RECENT DAY THERE ARE MANY ACCIDENT HAPPEN . THIS PRESENTATION IS ABOUT TO REDUCE ACCIDENT. USING LATEST BRAKE SYSTEM ANTILOCK BAKING SYSTEM
Anti-lock braking system (ABS) is an automobile safety system that allows the wheels on a motor vehicle to maintain attractive contact with the road surface according to driver inputs braking with abs preventing the wheels from locking up (ceasing rotation) and avoiding uncontrolled skidding. It is an automated system that uses the principles of threshold braking and cadence braking which were practiced by skillful drivers with previous generation braking systems. It does this at a much faster rate and with better control than a driver could manage.
There are four main components to an ABS system: Speed sensors Pump Valves Controller
SAFETY ELEMENT The biggest difference between ABS brakes and regular brakes is that ABS brakes should not be pumped. Regular brakes are pumped on hard stops to prevent the wheels from locking and sending the car into a skid. ABS pump the brakes automatically to prevent skidding and pumping the brake system on an ABS system can badly damage the brakes. There is normally a warning light in the dashboard that will tell you if there is a problem with the ABS. If the light comes on, take the car to a service station immediately.
The theory behind anti-lock brakes is simple. A skidding wheel (where the tire contact patch is sliding relative to the road) has less traction than a non-skidding wheel. If you have been stuck on ice, you know that if your wheels are spinning you have no traction. This is because the contact patch is sliding relative to the ice. By keeping the wheels from skidding while you slow down, anti-lock brakes benefit you in two ways: Youll stop faster, and youll be able to steer while you stop.
Most anti-lock brake systems are designed to switch off if any of the components fail. There are rare instances when a valve will stick open, but the brakes will usually continue to work normally. If the pedal doesnt fade or sink, that typically means the vehicle is safe to drive. You will have to pump the brakes if you find yourself in a panic stop situation, so its crucial to remain vigilant if your ABS quits working.
The advantages of ABS brakes (anti-lock braking system), are just as the meaning of their acronym implies, they eliminate or greatly reduce the possibility of brake lock up and therefore provide a better chance of steering out of trouble. ABS brakes were designed to combat the problem of tire lock up and uncontrolled spins. Since brakes are most effective at slowing the car at a point just before wheel lock up, a system that provides for wheel braking while preventing wheel lock up is very desirable. Use of ABS is simple you mash the brake pedal and the computer takes over. No matter what the surface, ABS adapts to it. Even professional race car drivers cannot adapt as quickly as a computer to changing surfaces. Most of those who live in the snowier regions know what patchy snow can be like. Steer ability of the vehicle is very well maintained.
Disadvantages: Stop Times - Anti-lock brakes are made to provide for surer braking in slippery conditions. Delicate Systems - Its easy to cause a problem in an ABS system by messing around with the brakes. Cost - ABS systems require significantly more parts than a traditional braking system. System damage - A variety of factors can cause the system INEFFECTIVE
Additional systems have been developed that enhance the benefits of the basic ABS. One of these systems is automatic traction control, called ATC. ATC uses the same components as ABS, but works at the other end of the speed spectrum—getting a vehicle started under slippery conditions. In operation, it senses each wheels speed to detect when one or more wheels "break loose" and start to spin. When that happens, it applies the brake on that wheel 12 to 15 times per second to let it slow down and regain traction. In demonstrations, vehicles have been held by blocks on an ice-covered grade. When the vehicles start and the blocks are pulled away, the vehicle without ATC spins its wheels and slowly slides backwards down the grade, while the ATC-equipped vehicle pulls its way up the ice.
Abs system work effectively even on rainy day snowy and other because it keep the tyre traction stay aligned on the road . when using ABS system a car will stay on the road even the surface of the road is wet. Mainly ABS system has been introduce in Malaysian car such as gen2, persona , inspira and latest model preve. The significant of these model using an abs system make a different level on it safety than the older model. You absolutely should not pump the brake pedal in a car with ABS
