ABS (Anti-Lock Braking System) is a very timely protective braking system used in vehicles. Which is being used in modern technology vehicles of the present time. In today’s time, the anti -lock braking system (ABS) is being used in almost all vehicles operating on the land.
What Is ABS In Car (Anti Lock Braking System)
(ABS) system is an anti-skid braking system that prevents the wheels of the vehicle from locking during braking. Due to this, when the driver applies brakes, the wheels of the vehicle get proper grip on the road surface. The ABS braking system connects the ABS control module to the brake booster, which sends brake oil pressure from the brake booster to the oil cylinder located in the vehicle’s wheels according to the brake pressure.
Whereas in the ABS braking system, speed sensors are installed in every wheel of the vehicle, which send the signal of the speed of the vehicle to the ABS control module. Based on these speed signals, the ABS control module receives input and output from the vehicle’s ECU. Which gives the driver more convenience to stop and control the vehicle efficiently. The ABS system works very quickly when braking and stops the vehicle most effectively.
ABS System Components
- Speed sensors : These sensors measure the rotational speed of the wheel or wheels.
- Valves: The brake line’s three separate settings for the valves allow, block, and release pressure on the brakes, respectively.
- Pump: On demand, these hydraulic fluid-filled pumps exert pressure on the braking drums or wheel disc calipers.
- ABS Module: The ABS’s brain, uses information from sensors to decide whether or not to apply the brakes.
How Does Anti-lock Braking System (ABS) Work?
Many parts of the ABS unit are activated in the ABS braking system and play an important role. such as an ABS control module, wheel speed sensor, wheel cylinder, pump, valves, brake booster, ECU etc. The wheel speed sensor in the ABS braking system senses the speed of the wheel and wheel cylinder oil pressure.
And during braking, the speed of the wheel and the signal of the pressure sends the ABS control module. such as: speed of vehicle wheels, velocity and deception in speed.
ABS Control Module based on this data Based on the data obtained by the wheel speed sensor, the oil pressure in all the wheel cylinders decreases and increases according to the wheel speed and the wheel of the vehicle, which both decline.
The ABS control module works more to the braking pressure of that wheel. This process is very fast. The ABS brake system module repeats about 20 to 25 times in 1 second.
Due to this, the wheel of the vehicle is not locked when applying brakes in an emergency. And the vehicle does not stop dragging on the road.
Due to this, the vehicle does not skid on the road, there is a possibility of gaining control of the vehicle in a short time even at high speed, and the driver has complete control over the steering of the vehicle.
FAQ’s
Q. Is it okay to drive a vehicle with the airbag light on?
If the air bag light is visible in your vehicle. So you can drive your vehicle with care carefully. But this can be a risky move. The ABS light coming on is a sign of some kind of error in the braking system of your vehicle, which can cause serious problems at any time. So you can get your vehicle’s ABS light diagnosed and repaired.
Q. Can Low brake fluid cause ABS light to come on?
Yes, if your vehicle has a low level of brake fluid. So your vehicle’s ABS light may be on.
Q. Where are ABS sensor located?
On a four channel ABS system, the ABS sensor is normally found in each wheel hub or rotor. In some rear-wheel drive systems, the sensor is installed in the rear differential.
