A computer-controlled high pressure system that assists the vehicle's normal braking system. ABS allows all wheels to slow at the same rate, thereby preventing loss of control.
An important safety advance in braking, this system uses a computer to monitor the speed of the wheels. If one or a pair slow down more than the others (which indicates skidding) it releases hydraulic pressure to the brake at that wheel or wheels, then reapplies it, typically 15 times per second.
A device which senses that one or more of the wheels are locking up during braking. It is controlled by both mechanical and electronic components. When you apply the brakes, the ABS will regulate the flow of brake fluid being delivered to the brake calipers. It must be remembered that a wheel cannot be steered unless it is rolling; so if the wheel is locked up, there is no steering control. By the use of electronic computers, the brakes rapidly alternate (at a rate of 30 times per second) from full pressure to full release. This process will also alternate from the left-front wheel and the right-rear wheel and switch to the right-front wheel and left-rear wheel. In this way both maximum braking and maximum steering control is allowed during braking.
This braking system senses any significant difference in wheel speed, from one wheel to another, when a vehicle is braking hard. When any of the wheels begin to lock up (completely stop rotating), ABS automatically reduces the braking forces to that wheel or wheels in order to keep all the wheels rolling – to prevent break-induced skidding. ABS can control all four wheels (cars and most 4x4s have this system) or any two. The system can group wheels together in "channels" of operation (i.e. a three-channel ABS system on a four-wheeled vehicle) or have one channel for each wheel (four-channel ABS).
System that automatically controls wheel slip or prevents sustained wheel-locking on braking.
System that prevents wheel lock-up by automatically regulating the brakes. ABS can decrease braking distances, prevent skidding and allow more control during sudden stops.
An antilock braking system is designed to stop the wheels from locking when you apply the brake, thus preventing skidding.
a vehicle braking system designed to compensate for bad driving. It senses when the brakes are about to lock and releases them momentarily. The lock and release sequence happens several times per second and provides the driver with some steering control.
A supplementary system to the base hydraulic system that prevents sustained lock-up of the wheels during braking, as well as automatically controlling wheel slip.
Advanced technology designed to prevent brakes from locking up regardless of brake pedal pressure. Anti-lock braking systems have become increasingly popular because they enhance traction in slippery conditions and allow you to keep steering control of a vehicle, even in a skid.
Vehicle brakes that sense when the wheels are locking up or skidding and adjust to avoid a skid.
Vehicles equipped with ABS use electronic sensors located near each wheel to decide whether the wheels are skidding, or locked up while braking if the driver has slammed on the brakes. If the tires are skidding, the system very briefly releases the brakes to permit the tire to regain traction to the road, and most of the time, this helps the driver stay in control. The instantaneous capture and release of the brakes when ABS is activated frequently makes the brake pedal to vibrate.
An anti-lock braking system (ABS) is a system on motor vehicles which prevents the wheels from locking while braking. The purpose of this is to allow the driver to maintain steering control under heavy braking and, in most situations, to shorten braking distances (by allowing the driver to hit the brake fully without the fear of skidding or loss of control). Disadvantages of the system include increased braking distances under certain conditions and the creation of a "false sense of security" among drivers who do not understand the operation and limitations of ABS.
