What To Write On A Hen Card

FUTURE BREAK SYSTEM (ABS)



Operation
The ABS works in conjunction with traditional braking system. Consists of a pump that is incorporated into the circuits of brake fluid and in a few detectors that control the speed of the wheels. If hard braking one or more wheels suddenly reduced its speed, the ABS detects and interprets what the wheels are about to be blocked without the vehicle is stopped. This means that the vehicle starts to skid, and therefore, to slide on the floor without control. To avoid this, the sensors send a signal to the ABS Central, which reduces pressure on the brakes done, without involving the driver in it. When the situation has normalized and the wheels spin again correctly, the system allows the pressure on the brakes to come and perform with all the intensity. The ABS control again the turn of the wheels and acts again if they are about to be blocked by the brake force. In the event that the system involved, the procedure is repeated very quickly, about 50 to 100 times per minute, which means that the driver perceives a vibration in the brake pedal.
allows the driver to continue having control over the vehicle's path, with the consequent possibility to avoid the obstacle causing the risk.

Using ABS keeps the
during braking coefficient of friction static, as it prevents slippage occurs on the road. Given that the coefficient static friction is greater than the friction coefficient dynamic braking distance is always reduced with ABS.
Although the ABS system is useful in almost all situations, it is indispensable on slippery surfaces such as wet or icy pavement, as in these cases the difference between
coefficient of friction static and dynamic is particularly high.
When driving on snow or gravel and no ABS brakes, there is the sinking of the wheels on the pavement, leading to an arrest of more efficient car. The ABS system, to avoid slipping on the floor also prevents the wheels from sinking, so that these types of surface, and desiring a stopping distance as short as possible would be desirable to disable the ABS action.
