Mirrors have a long and firmly established in our lives. First, of course, they drew attention to women. Then, as car ownership, they have become necessary as the air and men. As the number of cars on the road appeared and additional functionality, which seemed completely unnecessary before. On the first cars did not even have brakes. Eventually, of course, appeared. And the brakes, and headlights and turn signals, and the rest. Time goes by, all improved. Did not ignore the scientific and technological progress and the rear-view mirror. In large cities without them at all anywhere - is vital. Rebuilding and dynamic movement in particular. You can certainly turn my head, intending to reorganize, but quickly tired neck, and there is a serious risk to enter the rear vperediiduschey car. Mirrors let you see everything behind, and ahead of time. An experienced driver is able to instantly assess the situation and make the right decision. Truck rear visibility is even more relevant. All probably seen the whole garland of mirrors, particularly in Asian srednetonnazhnikah. They can see and position of the wheels when parking and entrance to the place of discharge, and objects that are behind, and even the dead zone of the review are not available full-time system. Of course, there are already cameras, but the mirrors do not give up. Often they are familiar, and most importantly - cheaper. There are quite ingenious solutions, such as a mirror periscope for the adaptation of RHD cars to the right-hand traffic. It is worth a penny collection, mounted quickly and allows you to see everything that goes into oncoming traffic, despite the fact that the driver is on the right. Additional mirror device in the cabin takes some getting used, but adaptation occurs very quickly. Minimum required field of view are regulated by national and international standards (GOST R 41.46-99 and Regulation № 46 UN / ECE). Naturally, the minimum zone is better not to be limited: more than you see - you ride confidently, respectively, have to resort to various tricks in order to see more. To increase the field of view side mirrors should be done with a small curvature, slightly protruding. They will be reflected more. Right hand mirror, even on domestic regulations must be spherical, or simply do not provide the required viewing area. It is quite natural desire of manufacturers to bring the vehicle to a panoramic overview, it is desirable to eliminate dead spots at all. Unfortunately, to do these things is extremely difficult, even in the design of constantly having to compromise. Pillar, the design of the machine often fail to review the ideal, so the development of a "mirror" the area are continuing. It is now almost all foreign cars are equipped with aspherical mirrors. What is it? This is a mirror whose curvature at the far edge of the driver much more. It can be seen better, but the distortion above. To ensure safety and order to show the driver the truth, the region with greater curvature is separated from the edge of a lesser curvature of the vertical strip. In-salon mirrors have a flat optical element and do not distort. Seen less, but you can easily estimate the distance to an overtaking vehicle. Now, of course, are sold already and so-called "panoramic" mirror with substantial curvature and significantly increase the viewing angle, but the professionals they are found not very useful. Impair the integrity and perception disaccustoms use regular side mirrors. So far we have considered only one aspect related directly to the mirror element. But there are other problems to solve that for a good review back producers is vital. Most important, of course, that the mirror was clear in any weather. Accordingly, in cold and / or cheese climate mirrors need heating. Usually it is included, along with heated rear window, but there are exceptions. On modern cars, as a rule, should the timer turns off the heating when the need for it disappeared as heating elements consume quite a decent amount of energy. Have not yet worked out a system cleaning mirrors, and even the expensive modern car while driving in the offseason has come out and wipe the mirror as dirt, zasyhaya the warm mirror cell, making the latter opaque. Is hard to come up with anything, as for the flat surface area created vacuum. They say that any solution to this problem already exist, but in modern passenger car anything like this has not yet seen. Another problem - driving at night and blinding headlights of a driver running track vehicles. Then again, making a few. Previously used one, now another. Each automaker chooses his own way. Here it is important to ensure an acceptable quality / price ratio, respectively, the structures used for budget cars can vary greatly with the premium segment. Now, basically, a mirror covered by a special tinted or use the principle of change of reflectivity. The basis of the latter method is the ability of some liquid crystals or electrolyte change its transparency under the electric field. The ultimate cost of the product in the last two cases are essentially different. Elektrohromirovannoe mirror on a BMW (auto shading) at the price varies with the usual tinted to the same body in about three-fold. According to a study Donnelly Mirror Corp., Preferred color rendering, are blue and yellow. They reflect a good range of blinding without compromising the transmission of information on road conditions. Elektrohromirovannye mirror is definitely better, but only under certain conditions. Their greatest disadvantage is not very high rate of change in the brightness of reflection. Well, a few words about usability. Now almost on all the machines setup mirrors by means of actuators that is undoubtedly convenient, though there are still low avtomobilchiki on which this operation has to perform manually. Left mirror still okay, but to go right away. It is strange that the budget makers have not guessed it do a complete set with one electric mirror on the right side, but in vain, I think, would enjoy success. Finally a bit of mirror in terms of details of the car. It is no secret that the spare parts are quite expensive, sometimes even too much. A side view mirrors defiantly stick out in different directions while driving, because of what is often suffer minor accidents. Mirrors made in China now quite common to see a sale or even order. Good option for the price. Quality is often worse, but so far the mirror element oblezet, held a couple of years, and for such period may be much to happen. The only thing I would like to warn that the Chinese comrades disregard refer to catalog number, respectively, buying a mirror, nice to be able to sample your old or what's left of it. It is also desirable at once to check connectors, electrical efficiency and operation of the heating. It's enough to come by piece on the machine.
