It has also been suggested that the results to date may also be partly due to lack of knowledge or incorrect assumptions amongst car drivers about how ABS brakes actually function. A German study found that ABS brakes can lead to changes in behaviour in the form of higher speeds and more aggressive driving. Īs with other forms of braking, the effectiveness of anti-lock braking depends upon road user behaviour. The task of the anti-lock brake system (ABS) is to permanently and effectively stop the wheels from locking, thereby stabilising braking. A recent study, however, indicates that anti-lock brakes may not contribute to crash prevention at all. However, while injury crashes decrease (-5%), fatal crashes increase (+6%). ABS brakes do not appear to have any effect on rear-end collisions. There are statistically significant decreases in collisions with pedestrians/ cyclists/ animals and collisions involving turning vehicles. There are statistically significant increases in rollover, single-vehicle crashes and collisions with fixed objects. Casualty reduction effect?Ī meta-analysis of research studies shows that ABS give a relatively small, but statistically significant reduction in the number of crashes, when all levels of severity and types of crashes are taken together. This is intended to provide additional steering in the emergency situation, not to decrease stopping distances. Such systems are now fitted to many new cars. The main purpose of ABS is to prevent skidding where loss of steering and control result from locked wheels when braking hard. After all, pressing a single pedal will activate all. The braking system is a complication device with a lot of parts, but its working seems very easy. It is used to slow or stop a moving vehicle, wheels, axle, etc. ESafety measures - known safety effectsĪnti-lock braking systems in cars (ABS) What are anti-lock braking systems (ABS)? A brake is a mechanical device designed to restrain motion by absorbing energy from a moving system usually by means of friction.
