Already more than 70% of motorists know, what is it ABS, and have this system in the car. For domestic automotive industry it is a certain novelty, and here foreign producers install it practically on each vehicle. What it in operation?
What is ABS in the car?
The modern ABS system (ABS - the anti-lock braking system of brakes) which is included in the car package is considered very useful equipment. It is established in order that when braking in a floor to prevent not controllability of the vehicle. For ABS there is no difference on what road there is a stop, the car will not start to skid that perhaps, in the absence of this system. The electric device is directed first of all to safety on the road.
Asking a question, what is it ABS and as it works, it is possible to present the main unit and sensors going from it. They are established on each wheel which is driving. The system works when pressing a brake and defines with what speed wheels rotate. If speed is too high, then excess pressure is eliminated, by means of the hydroaccumulator.
For what ABS is necessary?
Such ABS braking system is necessary for each car, it improves coupling of wheels with the road. Generally it helps out on a slippery or wet surface when the car can just cease to react to movements of a wheel. At its absence the reduction of a brake way, especially on a slippery surface is possible. Simple installation will help to keep controllability on any road and under any weather conditions.
How does ABS work?
The anti-lock braking system, available to many, works from several sensors and the main block. The simple option represents the scheme in which sensors read out the speed gathered in a wheel. These sensors help to prevent slipping, on any road surfacing. The complete set of a system includes the following devices installed in the car:
- the high-speed sensor – 2 or 4 pieces;
- valve;
- pump;
- control unit.
Proceeding from it, the principle of work of ABS is simplest. Activation happens only by sharp pressing a brake pedal, in the rest of the time the system stays idle. High-speed sensors wait for a signal at which it will be necessary to consider the speed of the movement of the car and to instantly lower it. The valve serve as the cylinders lowering pressure. The pump brings the valve into a starting position, and the operating block gives signals to all other components, for their timely work.
Ice and ABS
You should not think that the ABS system on ice provides an absolute guarantee of control over the car. It is influenced also by a condition of a protector and tires, the speed gathered on ice and experience of the driver. Lately began to release the tires manufactured especially for cars with ABS. They are prepared for sharp braking and prevent the movement of the car a skid.
Anyway ABS and ice, things almost incompatible. The slippery road is always very dangerous and for safety it is worth hoping not for the brake system, and for itself. Correctly picked up distance and speed of the movement will provide comfortable driving and will exclude stressful and emergencies. Automobile assistants are necessary, but it is necessary to hope for himself.
How to use ABS?
Professional drivers perfectly know, what is it ABS. Some consider it useless, but do not remove it from the car, excess safety is not superfluous. Inexperienced drivers should be trained, it is possible not to react at the right time. For a training there will be enough several times, everything that is required, it strongly to press for a brake pedal.
Direct work of ABS is that it reduces speed in wheel couple. With a pressure upon a pedal there is an unpleasant crash which it is heard in salon, but this normal phenomenon. The fact that the system performs the work will become clear also on strong vibration of a pedal of a brake. The valve control pressure and from it appears such effects to which it is necessary to get used.
Malfunctions of ABS
Problems can arise also at the best system, and ABS is not an exception. It is possible to correct them independently or to address to any service for maintenance of cars. Such breakages do not cause big problems to drivers and are solved approximately in several hours. The error of ABS is shown very quickly, and it is easy to find probable breakage.
- Safety locks burned down or were damaged.
- The sensor in the car became faulty.
- The wrong tires were picked up.
- Wire breakage.
People who though for 30% understand cars can reveal and correct these violations independently. For others there are specialized service centers, with modern computer diagnostics which in a minute reveals malfunction. To avoid these problems, it is necessary to watch car and at least to keep it clean.
Why ABS lights up?
If on the dashboard the ABS badge burns, it means that the system works incorrectly or is broken at all. Many drivers consider that it somehow affects brakes in general, but it not so. Such situation is not critical, some motorists have no it in a complete set and quietly steer the vehicle. As the main reasons for burning of a bulb are considered:
- the connection socket has no contact;
- one of sensors does not transmit a signal;
- the stupichny wreath is damaged;
- the control unit does not work.
By the cars equipped with the on-board computer, all malfunctions of a system decide on the help of the code. Having revealed and having eliminated the arisen trouble it is necessary to check operability of a system. It is possible to make it way of dispersal of the car to 40 km/h and sharp braking. Fir-trees the characteristic crash will be distributed, and the leg will feel vibration, that ABS is serviceable.
How to check ABS?
Not to take for a ride search of the equipment and equipment, pumping of ABS happens in specialized salons of maintenance. Codes show problem places and it becomes simpler to fix problems. It is independently possible to check only a condition of sensors and conducting, and here it will be more difficult to reach the control unit already. In general even full replacement of a system is not too problematic and financially expensive.
For and against ABS
Skilled motorists consider this system absolutely useless as are absolutely sure of the ability to drive. Yes, the brake way without ABS is almost twice shorter, but there is one minus - the car becomes almost uncontrollable. Faltering braking is safer not only for the driver, but also for other participants of the movement. The ABS function statistically gathers more pluses, than minuses therefore its began to establish practically in all cars of the twenty first century.
