Reference News Network reported on June 10 that western media said that the U.S. IHS automotive information consulting company issued a report on June 7 that the global sales of driverless vehicles will reach 21 million by 2035, significantly higher than the estimated value two years ago.According to the report of EFE news agency on June 7, the report believes that the reason for the bright prospect of driverless vehicle market is that while automobile manufacturers increase their R & D efforts, the relevant laws implemented by various countries are also developing in a favorable direction.It is reported that only two years ago, IHS automotive information consulting company estimated the sales of driverless vehicles by 2035 at 11.8 million.The report said that by 2020, the United States may become the first country to allow driverless cars on the road, and thousands of driverless cars will appear on the roads of the United States in that year. By 2035, the sales volume will increase to 4.5 million.However, China will become the largest driverless car market. The report predicts that China will have more than 5.7 million driverless cars by 2035.By 2035, the sales volume in Europe will reach 4.2 million, while the sales volume in Africa and the Middle East will also reach 1 million. Meanwhile, 1.2 million driverless cars will be sold in Japan and South Korea.IHS automotive information consulting company said that the global sales of driverless vehicles will reach 600000 in 2025, and the sales will continue to grow at an annual rate of 43% in the next 10 years.The company believes that 2025-2035 will be a decade of rapid growth in sales of driverless vehicles, because such vehicles will be accepted by all key markets around the world. In the future, driverless cars will provide convenient services and create a lot of new opportunities for the automotive industry.

Some people think that the paint surface without damage will not rust, but it is not. Although the surface of many cars is bright, the interior paint is very poor, and some manufacturers do not do fine in the details, which makes these places easy to rust.Most of the places prone to rust are the hinge part of the door. Because there are many screws on the hinge, it is easy to have holes when painting, and it is easy to rust after being stained with water. There are also the inside of the engine compartment cover and trunk cover, which are also easy to rust. For these parts, whether new or old, car owners should always check them, especially in wet and rainy seasons.If rust spots or rust marks are found after the warranty period, the car shall be repaired in time. In serious cases, it shall be repainted. If the corrosion is very small, the rust spots can be removed by grinding with sandpaper dipped in water. After the rust spots are completely wiped off, the primer and original or near color paint can be applied. When removing rust, the area should be slightly larger. Because some rust may be in the paint, it will continue to rust if it is not cleaned and painted immediately.In addition, slight scratches should be handled in time. Scratch repair car wax is widely used in car beauty. Its function is to quickly remove fine scratches on the surface of car paint and effectively control oxidation phenomena such as whitening and fading of car paint; At the same time, it can polish and maintain the car paint to make the gloss of the car paint more ideal. For less serious scratches, first dip a little repair wax with a clean cloth, wipe the scratches repeatedly until the scratches disappear, and then polish with a towel. Small scratches can be solved with a touch up pen. The appearance of this pen is similar to that of an ordinary carbon pen, but it is filled with car paint. It has two pen heads. One is as thick as a ballpoint pen and can repair finer scratches; One is like a brush tip, which can repair large scratches. It is understood that this paint repair pen basically covers all automobile brands, and the color similarity is also relatively high after paint repair. In addition, the touch up pen can also be matched with grinding paste. The grinding paste can be used before paint repair to smooth scratches and paint surface and increase the adhesion of car paint; After touch up, the paint surface may be uneven to varying degrees. At this time, the grinding paste can grind the paint surface flat.In addition, slight scratches should be handled in time. Scratch repair car wax is widely used in car beauty.

Comparison of fuel tank materials of automobile parts:In the selection of fuel tank materials, there are obvious differences between the two vehicles. Lang uses plastic fuel tank and Kia K3 uses metal fuel tank. From the perspective of safety, the toughness and strength of plastic fuel tank are usually better than metal fuel tank. Wenzhou automobile is equipped with plastic fuel tank, and it is not as easy to produce sparks as metal fuel tank in case of collision, friction or extrusion, so it is safer as a carrier of fuel. In addition, plastic fuel tanks are lighter and more plastic than metal fuel tanks. As for the cost, the production process and equipment of the two are completely different. Under the condition of mass production, the gap between the oil tanks of the two materials will not be very large.When the plastic oil tank was just launched, it was easy to age and had the problem of oil leakage, so it was not widely used. However, with the development of material science and technology, the plastic fuel tanks produced now have polymer oil resistant layers, and the original problems of oil leakage and aging have been comprehensively improved. Therefore, at present, more and more manufacturers begin to use plastic fuel tanks on cars.In fact, most of Beijing Hyundai's models are "loyal fans" of metal fuel tanks. From old Elantra to old Sonata, Yuxiang and Lingxiang to today's Sonata 8, they all use metal fuel tanks. Now, Langdong has finally abandoned this tradition and used a "more fashionable" plastic fuel tank, which can be described as a great progress.
