How Does Anti-lock Braking System (ABS) Technology In Cars Work?

ABS prevents the wheels from locking up, thus avoiding uncontrolled skidding of the automobile and reduces the distance traveled without slipping.

Driving on expressways can be enjoyable and thrill-inducing, as most of you surely know. One gets to unleash a car’s full potential. The city streets keep us grounded, but as soon as you hit the highway, there’s no looking back. You’ll almost never see a car going below 100 km/hr.

Anti-lock Braking System

 

The situation becomes particularly tricky during monsoons, as cruising in a vehicle at such high speeds is the perfect recipe for a disaster if the roads are slick. Nevertheless, it does happen, so what do you do in a situation on a slippery road whenever you have to suddenly apply the brakes of your car? Without an anti-lock brake system, the wheels of your car stop spinning and the car will start to skid. You’ll completely eliminate control over the car and the results could be deadly.

If the road is not patchy, rough and on a hilly terrain, then the journey is not often worth undertaking as all destinations are already enough crowded. – By Romain Grosjean

Anti-lock braking systems (ABS) take a lot of the challenge from the sometimes nerve-wracking event. In fact, on slippery surfaces, even professional drivers can’t stop as quickly without ABS as an average driver can with ABS.

What is the Anti-lock braking system (ABS) in automobiles?

As the name signifies, the anti-lock braking system is a safety system in cars and other automobiles that keeps their wheels from locking up and helps their drivers to maintain steering control. Also known as anti-skid braking system sometimes, it empowers the wheels of a vehicle to keep tractive contact with the floor so that they don’t go into an uncontrolled skid.

With ABS, you have more control in your car during situations such as sudden braking.Basically, it is intended to help the driver maintain some steering ability and avoid skidding while braking.

ABS Working principle

The basic theory behind anti-lock brakes is straightforward. It prevents the wheels from locking up, thus avoiding uncontrolled skidding. ABS generally offers improved vehicle control and reduces stopping distances on dry and slippery surfaces.

A skidding wheel (where the tire contact patch is slipping relative to the road) has less grip (grip of the tire on the road) than a non-skidding wheel. For example, if your car drives over a road covered in ice, it is not able to move forward and the wheels will keep spinning because no grip is present. This is because the contact point of the wheel is sliding relative to the ice.

ABS modifies the brake fluid pressure, independent of the amount of pressure being exerted on the wheels, to bring the rate of the wheel back to the minimum slip level that is mandatory for optimal braking performance.

ABS has four major components:

1) Speed Sensor

This sensor monitors the speed of each wheel and determines the essential acceleration and deceleration of the wheels. It consists of an exciter (a ring with V-shaped teeth) and a cord coil/magnet assembly, which generates the pulses of power as the teeth of the exciter pass in front of it.

2) Valves

The valves regulate the air pressure to the brakes during the ABS action. There is a valve in the brake line of every brake that’s controlled by the ABS. In the first place, the brake valve is open and it allows the pressure from the master cylinder to be transferred into the brakes.

In the second position, the brake valve stays closed and pressure from the master cylinder to the brakes is constrained. In the third place, the valve releases some of the pressure on the brakes. The third step is repeated until the vehicle comes to a halt. The resistance that you feel when braking suddenly at high speeds is actually the brake valves controlling the pressure which is being transferred into the brakes in the master cylinder.

3) Electronic Control Unit (ECU)

The ECU is an electronic control unit that receives, amplifies and filters the sensor signals for calculating the wheel rotational speed and acceleration. The ECU receives a signal from the sensors in the circuit and controls the brake pressure, according to the data which is examined from the unit.

4) Hydraulic Control Unit

The Hydraulic Control Unit receives signals from the ECU to apply or release the brakes under the anti-lock conditions. The Hydraulic Control Unit controls the brakes by increasing the hydraulic pressure or bypassing the pedal force to decrease the braking power.

ABS in operation

While braking, if a wheel-locking scenario is detected or expected, the ECU alerts the HCU by sending a current and commands it to release the brake pressure, letting the wheel speed to increase and the wheel slip to decrease. When the wheel speed increases, the ECU reapplies the brake pressure and restricts the wheel slip to a certain level (Note: When the braking action is initiated, a slippage between the tire and the road surface in contact will occur, making the speed of the automobile distinct from that of the tire). The Hydraulic Control Unit controls the brake pressure in each wheel cylinder based on the inputs in the system detector. Because of this, this controls the wheel speed. This process is repeated for the next braking operation.

Automobile Safety Two

Tips Driving a car becomes so automatic after a while, it’s easy to let safety fall through the cracks. But even if you’ve never been in an accident before, you should not lull yourself into a false sense of security, failing to carry out basic safety precautions that could save your own life, or those of your passengers, in a collision. These car safety tips can reduce your risk of getting into an accident and help you handle tiny emergencies like a flat tire.

1. Wear your seat belt properly.

The National Highway Traffic Safety Administration estimates that 15,000 lives are saved every year because drivers and passengers are wearing seat belts when they get in an accident. Seat belts keep the vehicle’s occupants inside the vehicle during a collision, restrain the strongest parts of the body, spread out force from the crash, protect the brain and spinal cord and help the body slow down after effect, reducing injuries.

In order for a seat belt to work, however, it must be worn properly. Ensure that the shoulder belt rests across your chest and shoulders — never across your neck. Don’t put the seat belt under your arms or behind your back. The lap belt should fit snugly over the hips. Seat belt extenders can be purchased for larger-sized drivers and passengers that maintain security while increasing comfort.

2. Ensure that car seats and boosters are properly installed.

Kids and babies need special protection in the car to prevent serious injuries and fatalities in an auto collision. The N.H.T.S.A. recommends that children be securely buckled into a car seat that is appropriate for the child’s age, height and weight. From birth to 12 months, infants should always ride in a rear-facing car seat; children aged 1-3 years must stay rear-facing till they reach the top height or weight limit permitted by car seat manufacturers. From ages 4-7 years, children should be strapped into a forward-facing car seat with a harness until they outgrow it, and then proceed up to a booster seat until they are grown enough to safely use an adult seat belt. Keep kids in the backseat at least through age 12.

Always consult with the car seat manufacturer’s instructions to install a car seat, or even better, have it properly installed at your neighborhood fire station. You can discover additional child car seat inspection stations at the N.H.T.S.A. site.

3. Never text while driving.

How dangerous is it to be diverted by the act of composing, sending or reading text messages while behind the wheel? Car and Driver Magazine ran a test that assessed drivers’ reaction times to brake lights while attempting to text on their mobile phones, and compared them to those of driving with a blood alcohol level of 0.08 percent, the legal driving limit. Driving 70 mph in a straight line, it took an unimpaired driver .54 minutes to brake while a legally drunk driver needed an additional four feet. But when the driver was sending a text, an additional 70 feet were needed to come to a stop. Another study found that texting while driving was the possible cause of over 16,000 street deaths between 2002 and 2007.

4. Do not try to multitask.

put down the food, makeup and other distractions while driving. While text messages have a dramatic effect on a driver’s ability to stay safe on the street, other distractions take their toll as well. Talking on a cell phone, eating, use of in-vehicle technologies like navigation systems and other visual, manual and cognitive distractions take the driver’s eyes, hands, and attention from the task of driving. Try to perform activities like setting your vehicle’s route, picking music and making cell phone calls before you start to drive, and pull over to manage distractions like fights involving children.

5. Be aware of pedestrians, bicyclists, and motorcyclists.

Roads aren’t just for four-wheeled motor vehicles; even in remote rural areas, there may be pedestrians and bicyclists that are not visible to drivers until they get too close. Always keep safe speeds and take additional caution when moving around blind curves or over hills. Be watchful for pedestrians crossing the street at intersections, especially when turning right, and give cyclists at least half a car’s width when passing.

Because motorcycles do not have seat belts, it’s all too simple for motorcycle drivers and passengers to be seriously injured or killed in a crash. Motorcycle drivers should avoid the blind areas of trucks and be extra cautious of other vehicles on the road. Of course, helmets are a requirement for motorcycle drivers and passengers. Drivers of other vehicles shouldn’t pass a motorcycle too close, as a burst of air from the car can cause a motorcycle to shed stability.

6. Pack a climate-appropriate emergency kit.

Roadside emergencies can occur at any time, and drivers should be prepared with supplies that could aid in getting help, making minor repairs and signaling your vehicle’s presence to other drivers. Consumer Reports recommends a basic kit containing a cell phone, first-aid kit, fire extinguisher, hazard triangle, tire gauge, jack and lug wrench, foam tire sealant or plug kit, spare fuses, jumper cables, flashlight, gloves, rags, pen and paper, disposable flash camera, $20 in small bills and change and an auto-club or roadside assistance card.

You may also want to consider additional clothes, water, and non-perishable emergency food. In cold, snowy conditions, a windshield scraper, tire chains, and tow strap, blanket, chemical hand warmers, small folding shovel and a bag of cat litter (for traction on slick surfaces) can be convenient. You can purchase pre-assembled roadside safety kits and augment them with items that suit your needs.
