How ABS - anti-lock braking systems work
ABS anti-lock system is one of the cornerstones of active safety of the vehicle. His job is to lock the wheels when braking, and thereby prevent the loss of adhesion between wheel and road. Vehicle ABS system is to be operated even under heavy braking.
ABS anti-lock system is one of the basic elements of active safety of the vehicle. ABS prevents the wheels from locking while braking. The system is still turning Wheel ABS, thus avoiding the loss of adhesion between wheel and road.Roll the wheel helps to maintain operation, stability and controllability of the vehicle in extreme situations (such as hard braking or when braking on slippery surfaces). Locked wheel does not transmit the lateral force and does not allow spin.
The system prevents the wheels from locking during braking, which automatically prevents the braking force on the brackets, as the wheels from locking. When the locking of the wheels to lose grip and the vehicle would be unmanageable,would not be allowed to change the driving wheel.
Each round has its own speed sensor, control unit, information on individual wheel speeds. When the controller receives a signal that the wheel stops, the reduced pressure in the brake system shortly, which will be shown, the wheel in motion again. ABS can be released for about 12-16 seconds x, and the system still provides relatively steering wheel rotation and vehicle (check - Car Kammova circle). Underemergency braking, ABS braking force to get the responsibility that they replace the wheels and the subsequent release of the wheels to lock in quick succession until the vehicle stops.
Each wheel speed sensor installed (the ABS wheel speed sensor) is provided, the image sensor of the yellow text of the brake disc. This gives the controller on the steering wheel. The monitoring and evaluation of the situation through the control valve or pressure reducing brake or wheel in motion again.
ABSSystem was developed by Bosch in 1978. But the history goes back even further. In early 20 th century, there have been discussions on how to prevent the wheels from locking under heavy braking. Bosch "device to avoid hard braking wheels of a motor vehicle." Already in 1936 announced a patent but only with the advent of electronic engineers, antilock brakes, which was sufficiently fast and robust for use in motor vehicles of development. The first commercial application of the ABSSystem found special equipment such as Mercedes-Benz S-Class and a little later in the BMW 7 Series range.
Bosch ABS system, but further developed. The result of the development of systems created (ASR systems, the rotation of the wheels from locking when driving off), Electronic Stability Program ESP. In recent years he has appeared in ABS with EBD (electronic brake force).
How do you know the work of the ABS system?
When braking on liabilitybetween the brake you hear intermittent rain. Interruptions caused by its activities, ABS caused only forgive when the pressure in the brake system. This reduces the braking force and the wheel is unlocked. Pedal in this area, such as kicking and brakes for further falls to the ground. Few experienced pilot could not resist and let the brake pedal, but it would be a mistake!
Braking distances on wet roads.
On the roads dry the vehicle without ABS, stopping distances shorter. In the wetLand has been diversity and the frozen surface of a vehicle may be equipped with ABS braking distance is shorter. An important advantage is still the possibility to control the vehicle during braking.
