It indicates when your ABS system is non-functional. Vehicles that are enabled with the ABS system often come with the ABS warning light. If it goes wrong you can expect that your wheel would lock. In ABS system, there is a microprocessor that controls how much and when to supply hydraulic pressure to the braking system. If it fails, it can no longer measure and relay data to the system. These common problems could arise from any component of the ABS system ABS sensor failureĪBS sensor system is quite important as it measures the speed of your vehicle and relays the data to the ABS system. But this trend is changing as nowadays the newer cars are getting fitted with ABS as standard across all the variants. Generally, manufacturers only incorporate ABS systems into their topmost variants leaving the mid and base variants aside. But on dirt or gravel or any non-tarmac surface, ABS will increase the braking distance.ĪBS system is a bit expensive. Disadvantages of Anti Lock Braking SystemĪnti Lock Braking System has no functional disadvantages. Having an ABS module in an EV can be highly helpful. However, not all the EVs are built with the ABS module. Electric vehicles are built with enormous speed to cover great distances and are also equipped with ABS. Electric vehicles are built with a good traction control system. ABS in EVsĪBS achieves the same objective in an Electric vehicle. But with the help of the ABS system, you will be able to brake effectively even when the surface is wet.
The lack of frictional force between the wet road and tyres can cause the car to spin out with almost no resistance force to decrease the velocity till you reach a dry part of the road. When driving on a slippery or wet road surface, even a slight touch to the brake pedal could initiate the wheel lock cycle.Īt such situation, wheel lock can be most disastrous. Because in the case of ABS installed vehicle, the wheels will still be rotating after application of brakes.ĪBS is most useful in slippery road conditions.
Purpose of anti lock braking system driver#
Unlike in the situation of a wheel lock, the driver will be able to steer the car easily even in full brake effort with the ABS system. How does ABS help?īiggest advantage of the Anti Lock Braking System is that it lets the driver have control even when he/she is applying the brakes at full force. Traction control system is another safety measure that is similar to ABS and it controls the individual spin-speed of a wheel through braking. But still there was a need to put in place a system like the electronic brake force distribution which would automatically detect and regulate the amount of hydraulic pressure which would be sent to the wheels. This lock remains until the pressure is removed.Ĭadence braking used to be one effective way of reducing the effect of skidding eon a slippery surface. This makes the hydraulic pressure, which is distributed to the wheel in bringing the wheel to stop, to also lock the wheel in a certain direction. Sometimes this braking force is too much. This, in turn, decreases the braking effort on that wheel. The sensor immediately detects that sudden decrease in speed and sends a signal to the control module.Īfter receiving the signal, the control module processes the decrease in speed as a wheel lock and orders the pump to release some braking pressure through the release valves. On application of brakes, when your wheels lock up, their rotational speed becomes zero.
They are 4 wheel speed sensors i.e., one for each wheel, a hydraulic motor, pressure release valves and an electronic module that is embedded into the car’s ECU i.e, Engine Control Unit. The ABS system comprises of 4 main components.
The volume of braking force required to bring the car to a safe stop is responsible for the wheel locking. It syncs the braking operations on both front and back tyres. Working of an ABS systemĪBS works like a Combined Braking System. This is where ABS manufacturers decided to step in. This is dangerous when the wheels are locked when heading towards some objects or people. It would become unable for the driver to change the direction of the vehicle. While driving, whenever a driver applies sudden braking, the car wheel would automatically lock in a particular direction. Comparision of a vehicle with ABS and without ABS This technology enhances safety during sudden or emergency braking. What is ABS ?ĪBS is an acronym for Anti-lock braking system.
