Newer HGV's are combating strong winds on the motorway by using ABS to apply the brakes to wheels and help keep lorries on the straight and narrow. Although motorcycles and high sided vehicles such as heavy goods vehicles are still vulnerable.

Most modern cars are now built to be able to deal with strong crosswinds. TCS works by shifting torque through differentials to wheels that the ECU deems to have better traction in comparison with a wheel that is slipping. Although this shouldn't be confused with actual traction control systems (TCS) that are used to prevent wheel spins during acceleration. ABS is used to help restore grip to wheels that slip, by slightly applying the brake.

In the event that ABS fails, drivers should pump the brakes manually.ĪBS is also used as a form of traction control in a range of modern cars. Meaning a car or motorcycle that experiences locking on all wheels simultaneously wouldn't trigger ABS.

ABS works by detecting and comparing locking on individual wheels. Similarly, on the ice, ABS can be more of a hindrance than a benefit because of system limitations. Whereas ABS would detect the locking of a wheel and attempt to stop any skidding or locking from occurring. On snow, a wheel that skids or locks will build up a wedge of snow helps vehicles stop. But the results are quite different on surfaces like snow, ice and gravel, where braking distances are actually increased.

ABS can be used to change when a driver commits to braking before a corner and can also help protect tires from excessive wear.ĪBS has been proven to reduce the risk of crashing when being used on typical road surfaces like bitumen and concrete. In the racing world driver aids such as ABS and traction control systems (TCS) take on different roles. Decreased stopping distance is not guaranteed by ABS and is a secondary effect. In ideal conditions vehicles equipped with ABS generally experience shorter stopping distances than those without. But to help drivers maintain control of their vehicles in heavy braking situations. The primary purpose of ABS is not actually to help cars stop faster.

Motorcycles equipped with ABS are also 37% less likely to be involved in a fatal crash, according to a study by the Insurance Institute for Highway Safety (IIHS). Nonfatal crashes have reduced by 6% in cars, and by 8% in LTV's.

Wheel sensors detect skidding or 'locking'ĭrivers are benefitting from the effectiveness of ABS according to an 11-year study in the U.S, conducted by the National Highway Traffic Safety Administration (NHTSA).

So essentially, ABS works in three stages: This stops the wheel or wheels from skidding and helps keep the driver in control of the vehicle. When a lock-up is detected, ABS pumps the brakes, 100's of times a second. Although not all ABS systems are the same, with some only preventing wheels on the rear axle from locking up. Sensors on each wheel are used to detect 'locking' or when a wheel stops moving and starts to skid. How does the Anti-Lock Braking System work?ĪBS works by releasing and then reapplying or 'pumping' the brakes to a motorcycle wheel or car wheels in heavy braking situations.

Controller - The electronic control unit (ECU) is the brain of the ABS and uses data from the sensors to determine whether or not to pump the brakes.

Pump - These pumps are filled with hydraulic fluid and apply pressure to the brake drums or callipers on demand.

Valves - Valves in the brake line allow, block and release pressure on the brakes by assuming three different positions.

Speed sensors - These sensors monitor how fast the wheel or wheels are rotating.

The four major components of a typical anti-lock braking system are: Today, anti-lock braking is now standard on virtually all new cars and motorcycles and is used not only to aid steering whilst braking but also to help with traction control. Although, it wasn't until the 1970's that ABS was adapted and introduced to the commercial vehicle market on a large scale. The first primitive form of ABS was developed in the 1920's by French pioneer Gabriel Voisin, initially to aid braking on aircraft. Commonly known as ABS, or sometimes anti-skid braking systems, anti-lock braking systems help prevent car and motorcycle wheels locking up and improve steering control whilst braking.
