The auto-corrector headlights to xenon with their hands: description, principle of operation

Statistics show that about half of all accidents occur in the dark or in conditions of poor visibility. According to experts, a large part of the emergencies caused by the lighting of the car. To improve the quality of lighting designed this device as an auto-corrector of headlights to install on any owner.

It is Clear that this issue could not long be overlooked. Therefore, since 1990 the system of automatic correction were equipped all cars produced in Germany. Since 2010, the mass use of xenon lighting devices, each car device must be present.

The Need in the correction system

When driving at night it is important to spotlight well-lit path. However, the correct adjustment is not in all cases contributes to the safe movement in the twilight. This is because in cases of suspension changes to the car due to loading the trunk or the passenger presence, the luminous flux changes its path. As a result, this leads to a decrease in the level of illumination of the headlights and dazzle oncoming drivers.

Therefore there is a need for continuous adjustment of the luminous flux relatively vertical plane by means of special devices (do not want to learn how the auto-corrector headlights). There are almost similar devices – sensors for automatic headlights. But the basic difference between the two, so don't confuse them.

Advantages of xenon lighting

Currently, the halogen lighting devices are losing their relevance and for obvious reasons, are replaced with xenon headlights. They owe their name to the name of the gas – xenon, which is passed through the electrical discharge, which leads to the glow. In addition to the gas under high pressure, the glass bulb of the headlamp contains less than 1 mg of mercury and metal salts. What is one of the key benefits.

But beyond that, it is necessary to highlight three key points that essentially distinguish xenon headlights among other analogues with more prefix:

1. Bright light.
2. Secure lighting.
3. Long lifespan.

The Light from xenon headlights are significantly brighter than halogen sources. And no matter far or near light. The light has a bluish tint that brings it closer to the day. This significantly improves nighttime visibility.

Setting the auto-corrector headlights for xenon, you will notice the better contrast and color depth, reducing eye strain. Moreover, their light does not blind oncoming traffic and is better reflected from special paints on road signs.

But most importantly – the life, which is much higher than halogen headlamps (2 times or even 3). Due to the absence of filaments, xenon lamps are more resistant resist shock and vibration. And thanks to the use of ionized gas, 25% reduced consumption of electricity. If you're lucky, the lamp can last throughout “life” of the vehicle without replacement.

Safe driving

At the present time In connection with the increase in the production of cars, in the cities there is a large traffic flow. In such circumstances, it is important to ensure optimal distance to the vehicle ahead, which is easy to achieve by using auto-corrector headlights (vases etc.). Especially when traveling in the late evening or at night. This requires high precision adjustment of lighting fixtures.

Starting in 2010, cars with xenon headlamps must be present correction system. Only in this case you can protect yourself and other road users. Besides, special corrective devices give a full guarantee that all road signs and markings will be clearly visible. At the same time bright and powerful lights will cause blinding of other drivers.

Historical background

Leveling are equipped not only with modern cars, in the history there were cases of the use of such systems a few decades ago. In far 1950-e years such devices were put only on expensive cars. At that time, the headlight adjustment was made manually, for that answer a mechanical drive. Static lighting controller (formerly athe similarity of the auto-corrector headlights) were installed directly at the headlights and their adjustment was carried out before each trip.

Since then, the technology has been continuously improved, and in 1970-e years have appeared the possibility to adjust the headlights from the driver's seat. This was carried out through different mechanisms:

• Hydraulic;
• Vacuum;
• Electrical;
• Pneumatic and other.

However, these devices quickly become obsolete, since drivers was difficult to determine the direction of the beam. In particular, difficulties arose in the case load of the vehicle. Over time, the headlight adjustment is performed automatically.

The Principle of operation and types of headlight range control

In the system, headlamp levelling sensor included tilt of the vehicle, installed in its rear part. His responsibilities included the determination of the height relative to the road surface, the inclination angle calculation and transfer of all information to the control unit. Based on this information, the controller of the auto-corrector headlights for xenon for making decisions. That is, if necessary, the signal from the computer changes the angle of the light flux in the desired direction, is responsible for what corrector.

Almost every modern car is equipped with a system of adjusting the headlights. It is divided into two types:

• Quasi-static;
• Dynamic.

Between these systems there are significant differences, and one of them is faster and more secure. Is more detail to consider, based on what their principle of operation.

Quasi-static proofreaders

In the quasi-static part of the device includes the following components:

• Orientation sensor of the car body (two pieces);
• Actuators (each spotlight);
• Switch the headlamp levelling switch (for manual configuration).

Sensors are associated with the axes of the car by means of special rods. Also here you can include the control unit. The principle of operation of this system is based on the change in the angle of body tilt that occurs when load or driving at high speed. Unfortunately, the installation of the auto-corrector headlights of this type is not entirely rational, since the response time of the sensors is poor. The efficiency of spell check is increased by setting the switch on the dash for manual adjustment of the headlights.

If you use an auto mode, the adjustment occurs with the participation of the control unit. For this purpose, the controller receives and processes all information regarding the location of the body and the vehicle speed. The data of the angle they provide these sensors, and speed information it receives from sensors ABS.

Dynamic proofreaders

His appearance dynamic autocorrector headlights are required a massive transition in xenon lights. This is due mainly to the fact that a powerful luminous flux of xenon is more dangerous than the light from halogen counterparts. Even a short bright flash will cause blinding of the driver of an oncoming vehicle and cause an accident. It is therefore vitally necessary adjustment of the headlights. The spell check will handle this case in the best way.

The Main difference of this system from the discussion above is that it is much more responsive to the changing angle, speed, height of transport. Time is spent very little – a fraction of a second. That is, it does so almost instantaneously, which is very important in the case of xenon headlights.

The dynamic corrector luminous flux will always remain at a predetermined level in any situation the vehicle is in motion:

• Acceleration;
• Cornering;
• Braking
• The rough road.

So, no matter how bright the lamp is, for all other drivers they are completely safe.

Setting up

To install the spell check you can use the services of employees of a HUNDRED or to do all the work yourself. As a rule, if the decision is to set the auto-corrector headlights with their hands on the car may already be installed on the device. So you should appreciate his work. And, if necessary, to replace the stock hydrocollator other device, it is necessary to dismantle it.

Many drivers prefer Electromechanical autocorrection because of the relatively cheap prices. If the standard device is out of order, it will be a great alternative.

Removing a staff system

The Dismantling of established hydrocollator begins with the cutting of pipelines and drain of fluid. They are usually located near the battery. This is followed by the operation of lifting the main cylinder. For this you will needscrewdriver, which you need to press the latch that secures the cylinder body. To get him out for the start of the housing counterclockwise until it stops and pull.

The next stage of the installation of the auto-corrector headlights, you can go to the salon to remove the handle from the block hydrocollator held by the nut. And after the control unit will be removed along with the piping, you can move on to dismantling of the rubber tube stub bulkhead.

After this is to prepare the wiring, wire by selecting the desired section and length. One side of the transaction need to solder the terminals to the connection module of the control unit. After the wires are routed through the hole in the bulkhead where there had previously been a pipeline. The other end of wires soldered to the connecting module of the drives. Usually in the configuration of the auto-corrector to the pads are rubber protective covers. But in their absence you can use sealer or heat shrink tubing.

For food, there are two thick wires and the terminals of “mother” in the amount of 4 pieces (one wide and three narrow). The auto-corrector headlights works effectively in the event of receipt of power the dipped beam headlamps. This should connect to:

• Terminal No. 10;
• Switch No. 64;
• Power supply rear fog lights.

The Mass can be connected using the free terminals of the wires leading to the ignition relay. Then install the drives to the original location and lock washers.

Generic version

There is a universal device, which produces the German company Hella. The device can be installed on any car, and it can act as a standalone system or be an addition to the manual adjustment of the headlights.

The Principle of operation is based on the latest readings of the ultrasonic sensors, which are fixed in the lower part of the body at a minimum distance of 25 cm from the road. From the sensors the control unit receives the necessary information regarding the magnitude of the angle of inclination of the car body.

Performing necessary calculations, the control unit sends control signals to the actuators of the auto-corrector headlights Hella. They, in turn, depending on the situation change the direction of light.
