Mercedes Benz wants to completely change the experience of your bus ride. Mercedes-Benz announced the Vision of the Future Bus in July. This semi-automated driving bus has successfully completed a 12-mile test, including passing traffic lights, tunnels, and avoiding pedestrians. test. To develop the future bus, Mercedes developed a bus optimization system called City Pilot based on the self-driving truck platform. The system can be safely navigated by means of a camera system, radar sensors and GPS. Although the bus will already have many automatic features in the future, Mercedes is not currently planning to release a future bus with no drivers at all. Mercedes-Benz Autopilot Bus Completes Road Test to Hide People, Identify Traffic Lights Andreas Mink, director of engineering for the Mercedes Bus Project, said: “Driving buses are not currently legally available on public roads. And this is not our goal. Instead, driving There is a lot of responsibility involved in the job responsibilities of the staff. We try to make this task as simple as possible, not replace it." What Mercedes is really admiring in the design of its driverless buses is the interior design of the cars made up of three different areas. The central area is called the "quick area" for short-distance passengers to use standing; there is a "rest area" at the back of the carriage for long-distance passengers; there is a "service area" near the driver for passengers to use when viewing relevant information. Ming Ke said: "The interior design of the bus in the future has put forward many ideas in the area of ​​passenger zoning. The design in this area has not changed for decades. The purpose of this internal design is to make the passenger compartment more comfortable and weaken the concept of strict zoning. It provides both an open space and a comfortable little space and information access area." It is unclear whether people will ride by car, but Mink said that the bus will not provide the function of guiding passengers to the appropriate area in the future. But no matter what, changing the internal space of the bus, which is usually very narrow, is an interesting attempt, and Mink also said that the standard passenger capacity of buses in the future is the same as regular buses, which is 105 people. Mercedes-Benz Autopilot Bus Completes Road Test to Hide People, Identify Traffic Lights Mercedes also claims that the future bus will save more energy than the current regular bus because it is semi-autonomous. Ming Ke said: "We expect that the future bus energy consumption will be significantly reduced, because the bus can detect the location of the bus station and the location and status of traffic lights in advance and optimize the acceleration and driving modes. Consistent driving mode can be reduced Energy consumption and emissions reduce wear and tear, and this is good for passengers." Ming Ke added that in the future, the bus may be equipped with an electric driving system. It is unclear when we will be able to see future buses on public roads, but Mercedes plans to invest approximately 227 million U.S. dollars in the development of city buses by 2020. Mink added that the bus needs further testing, and Mercedes plans to add more driver assistance to the bus before it officially launches the bus. Precipitated Calcium Carbonate
Uses: Can be used as filler in rubber, plastics, paper, paint and ink industries. Widely used in organic synthesis, metallurgy, glass and asbestos production. It can also be used as a medium seeding agent for industrial waste water, a antacid for stomach and duodenal ulcers, a detoxifying agent for acidosis, a SOâ‚‚ eliminating agent in SOâ‚‚-containing exhaust gas, a dairy cattle feed additive and an anti-sticking agent for oil felt . It can also be used as a raw material for tooth powder, toothpaste and other cosmetics.
Usually used as a filler, widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, construction supplies, food, medicine, textiles, feed, toothpaste, etc., as a filler to increase products The volume is reduced, and the production cost is reduced.

Light Calcium Carbonate is made of limestone, and can be used in daily chemical products such as tooth powder, toothpaste, cosmetics, etc. It can also be used in organic synthesis, metallurgy, glass and asbestos production.
The particle size of light calcium is smaller than that of Heavy Calcium Carbonate, the oil absorption is larger than that of heavy calcium carbonate, and the price is higher than that of heavy calcium carbonate. They are all commonly used fillers in latex paint, and they are best used together. Light calcium is better in terms of sedimentation, but its oil absorption is greater than that of heavy calcium, and the price is generally more expensive than heavy calcium. Although it is not as stable as heavy calcium, it is stable. Even for exterior wall paint, its application amount is also very large. of.
