8. Summary

Today, almost all cars that have xenon lighting should be equipped with a headlight auto-corrector. Its main task is to align the headlights so as not to blind the drivers of the oncoming lane. The principle of its work is that when changing the position of the car in the horizontal plane, the direction of the light flux of the headlights is automatically adjusted. This can occur when lifting or lowering the vehicle or when the vehicle is not loaded uniformly. Further we will consider in more detail the main functions of this module.

Basic principle of action

For full-fledged auto-corrector operation, a special sensor is installed at the rear of the machine, which determines its angle of inclination. Information is regularly fed to the control unit, which in turn turns the headlights in the right direction.

Imagine the situation: the car trunk is heavily loaded or the rear seat is completely occupied by passengers, in which case part of the car sags. Then the headlights are directed upwards, and this leads to an incorrect direction of the light flux and poor lighting in the dark and in bad weather. It can also negatively affect the situation on the road.

The sensor instantly detects this change and the electric corrector sets the headlights at an angle that is necessary for the horizontal plane, thereby compensating for the subsidence of the body. Everything happens automatically and imperceptibly for the driver. Deciding to purchase headlight range control , you will no longer worry about the fact that the wrong direction of the light will interfere or annoy oncoming drivers. In addition, you will know that your car will provide you with 100% the right light, which will positively affect comfortable driving in the dark.

Mandatory use of headlights

In many countries, and Russia is no exception, the auto-corrector is considered mandatory for cars that have xenon headlights. Xenon has the following characteristics:

• very economically consumes car energy;
• provides you with light that is as close to daylight as possible;
• the xenon light beam does not scatter when it rains, so such headlights show themselves perfectly in bad weather.

But they have a significant drawback - they can blind drivers of oncoming cars. In order to avoid this, it is necessary to equip the headlights with a corrector. As a rule, when installing xenon, manual corrections are installed, but this is not always convenient and effective. The auto-corrector always selects the exact and correct position of the light beam. Having decided to install a similar device on your car, you automatically relieve yourself of constant control of the headlights position. As a rule, the auto-corrector kit includes:

• Two ultrasonic sensors (on both headlights);
• Electronic control unit;
• Necessary wiring for full operation;
• Drive devices.
• Consider the most popular and highly sought after auto-correctors produced by Hella and SmartEye.

Auto-corrector for headlights Hella

Among the many companies that produce this module, the German company Hella is currently the leader. You will receive a quality product that is thought out to the smallest detail, with it you will forever forget about such a problem as the discontent of oncoming drivers. In addition, you will know that your machine will always undergo a technical inspection. Auto-corrector for headlights Hella can be installed on any make and model of car. It can be used as an independent device or to complement a manual corrector. The kit includes instructions with which you can independently install. The calibration process is very simple. The built-in indicator displays all the information about the angles and projections of the change, both in automatic and in manual mode. Switching modes is done independently as necessary.

Hella Auto Corrector Features

• Automatic headlight range adjustment;
• The programmable angle of the optics depends on the load of the machine;
• The ultrasonic sensor calculates the position of the car body relative to the roadway;
• Powered by cars 12 V, there are kits that are designed for 24 V;
• In the presence of regular xenon, auto-correctors are mandatory for maintenance.

SmartEye Auto Corrector

This model of auto-corrector (optional) is intended mainly for the conversion of factory systems of a machine that are equipped with an electromechanical device. Included are:

• Electronic unit with position sensor;
• The monitor with which the adjustment is made;
• Wiring;
• Two types of plugs for connecting to a device monitor.

The module is not equipped with its own activators for changing the headlight range. The principle of operation of this device is to determine the position of the car body in relation to the plane of the road. Using the sensor, information is read, it is installed on the housing. Then a command is sent to change the angle of the headlights in relation to the loading of the car.

Important information to know when installing

Each universal device automatically calculates the value of the angle of raising / lowering the headlamp at a certain load of the machine. All this happens thanks to the latest design ultrasonic sensor. The basic rules that you should definitely consider are that the sensor must be mounted at a distance of at least 250 mm from the road surface. If you have a desire to purchase new headlights, you do not have to re-buy the auto-corrector.

Key features of auto-corrector

• Rated voltage 12 V;
• The tilt angle is calculated according to several special programs, this choice depends on the size of the headlights and their type;
• The headlight position adjustment time is 2-5 seconds;
• Installation SmartEye Auto Corrector is an important point when completing maintenance (GOST requirements and European standards).

Summary

The headlight auto-corrector is mandatory for cars that are equipped with standard lighting. This module will positively affect the quality and direction of lighting, even if your car is loaded to the maximum. WITH auto-corrector You don’t have to worry about the fact that the light of your car can negatively affect the comfort of movement of oncoming lane drivers. If the car is equipped with an auto-corrector, then you will be provided with easy and unhindered passage of the next technical inspection. Let the light in your car be right.
