ABS Technology and Benefits

Anti-lock breaking system is commonly referred as ABS widely used in automotive vehicle for safety purpose. Vehicles like cars, motorcycles, buses even trucks are equipped with ABS technology to prevent accidents.

ABS Technology

When we apply brakes, ABS anti-skid system prevents wheels from skidding and locking, while maintaining required contact with the road.

Bikes like Suzuki Gixxer, Hero Xtreme 200R, Honda CB Hornet 160R, TVS Apache RTR 180 many others uses ABS tech.

Cars like Maruti Suzuki Swift, Maruti Suzuki Baleno, Hyundai Elite i20, Hyundai Creta, Honda Amaze and many others uses this awesome technology to keep passengers and driver safe.

You may curious what is ABS and how it works. So we shall share it in brief here.

What is ABS Technology?

As you know, ABS stands for anti-lock breaking system. ABS actives when you paddle breaks, it may be sudden or in any situation. After breaking wheels locks up and skids. Also do not stops before braking distance, but when ABS equipped bike or car paddles the brake, it prevents from locking the wheels and its sensor works smartly to make a side way.

It can be better understand in this video. Watch this.

Anti-lock Braking System (ABS) Working Principle

The theory is simple. ABS prevents the wheel from locking up as we said earlier to avoid any uncontrolled skidding. ABS decreases stopping distances on dry and slippery surfaces as well.

Major Parts of ABS

ABS has four major parts:
1. Speed Sensor
2. Valves
3. ECU – Electronic Control Unit and
4. HCU – Hydraulic Control Unit

1. Speed Sensor

The work of speed sensor is to monitor the speed of each wheel and determine the required acceleration and deceleration of the wheels.

2. Valves

The work of valve is to regulate the air pressure to the brakes when ABS is applied. There are three positions of valve, when ABS is applied. In first, valve opens and allows the pressure from the master cylinder to the brakes. Second position involves the brake valve remains closed and pressure from the master cylinder to the brake is constrained. And in third, the valve releases pressure on the brakes partially.

3. ECU – Electronic Control Unit

ECU is the main part of the ABS and its work involves to receive, amplify and filter the sensor signals for calculating the wheels rotational speed and acceleration. To control the brake pressure ECU receives the signal from sensors in the circuit.

4. HCU – Hydraulic Control Unit

The HCU unit releases brake under the anti-lock conditions, when it receives signal from ECU. By increasing the hydraulic pressure HCU unit controls the brakes and reduces the braking power.

Benefits of Anti-lock Breaking System

The benefits of ABS includes, preventing from skidding, lower insurance cost, high resale value, traction control.

Prevents from skidding: As mentioned earlier, it traction control over road on slippery or dry condition is very good. ABS has proven life saving modern technology.
Traction Control: It’s anti skidding and locking technology makes wheels smooth traction with road.
Lower insurance cost: By its proven technology, customers avail discounts.
Higher resale value: ABS Equipped vehicle resale value can be more comparative to non ABS. Most of the modern cars and bikes are available with the ABS Technology.
