Kelisidian·e waved his hand right next to the man, said he wanted a nail Clipper, when speaking, he also touched his chin and knee. It all sounds mundane, but if you know that, when he sat in a 40-ton truck, and the car was in Las Vegas at a speed of 60 miles per hour on the highway, more importantly--he has no driving nor how much attention on it.
This car is called Inspiration (ideas) is Folena high-tech version of the truck, and is first in the world to get automatic driving trucks. Keith is a member of the engineers of the company, it took them 6 months of intense work preparing for the shows this week in Nevada.
In fact, the van all Daimler companies still hesitate whether to boast of Inspiration, and its meaning is an understatement. As company executives put it, this is an automatic 18-wheel trucks, but it will not change by itself the driveway, within 10 years, it would not be listed, and can never replace the human driver.
Maybe he was telling the truth, but Inspiration can claim to be a step in the direction of our unmanned. Guerlain iPhone 5 Case
Generally, points of discussion focused on how to drive automatic cars, because a lot of people believe the technology could lead to safer, more energy-efficient products. Technology giants such as Google, is developing the hardware and software just to brush Facebook enables ordinary drivers to sit in the car without always grabbed the steering wheel and stared at the dashboard. Maybe on the Van's achievement was not so bright, but their vital for the economy.
In 2012 alone for a year, United States nearly 4000 people have died in a car accident, in which more than 90% are caused by driver error. Even if they developed the system only works on the high way, also provide a big help, because the big truck there most of the time.
Move towards a large container truck has this shift, active safety devices are installed on them, such as blind-spot monitor, adaptive cruise control and lane departure warning system. On the Foundation of this type of automation technology – for obvious reasons, said mosikuite, head of Boston Consulting company "commercial motor vehicles is a security problem, so any attempt to make these vehicles away from the trouble is extremely valuable. "。
Manufacture of 20 years 6 months
Mercedes Benz Daimler has spent 20 years studying the autopilot. Inspiration--with most of the technology include radar, cameras, computing resources, and electrical construction, have had a long business records, they are used for safety features, such as lane departure warning and adaptive cruise control.
Long before 2000, Mercedes radar installed in passenger cars for the first time. And now when they design the vehicles of the future, as an option to drive, and front-row seats can be turned to face the passengers in the back. This year, for trucks Daimler began selling a "Detroit Assurance" systems, including adaptive cruise control, lane departure warning and blind spot monitoring.
Inspiration of development work, the upgrade will be free to run and control the speed of a truck system, only started 6 months ago. Development team mainly from United States personnel, both from Germany's help.
Inspiration limited was made in automation of step only when the trucks on the highway, and after a certain speed is reached the system will start, and will allow the truck to keep a safe distance with other vehicles and to ensure that vehicles in the driveway. It does not itself change lanes to overtake, and if when the truck when it encounters a situation that cannot be handled by the system, such as heavy snow or when the lanes blurred to remind humans to take over driving operation.
This part of the mechanical engineering of the project smoothly, in large part because the company had already done a lot of work. Although trucks require different brake, but people involved in the project, said everything "already knew". For example, the vehicle is powered by a pneumatic device, so Daimler with a magnetic valve to control pressure in the drive, and so on. Support Inspiration power structure as a satellite centre, although the speed control and lane keeping system work separately, but there is a central device to monitor parts and make a decision at a higher level, such as reminding people to control driving. A system like this, data collection to a separate system, like the human brain. Daimler has developed out of the central system, but before the market, their engineers are working to lower costs and reduced size.
From the look of this car, you cannot find it on the road and an ordinary car and what is the difference between. Cab in front of the radar is very unattractive, and wind-proof cameras are hard to attract attention. In fact, in the upper part of the windshield installed a camera that can read track information. Embedded into the grid of radar detection range, can be scanned within 800 feet in front of obstacles. But that after the car failed to detect the sensor, because the company did not consider it necessary. Nor has it shop communication system, does not have the LIDaR system. Software algorithm was developed by the automated system of Mercedes-Benz passenger cars and the adapter version. Guerlain iPhone 5 Case
However, the most obvious difference is the blue LED lights mounted around the car group. Embedding them in the car on the grille and headlights, and the camera screen could one day replace the rear view mirror. Inside the vehicle there are more subtle changes, the floor is made of wood, while the cab rear sleeping area brush perfect white, with leather chairs, make people feel more comfortable.
UI
Visually the most obvious change is the "HWP" red button, set between the button lamp control and air conditioning. Use it to open the named "highway pilot" (Highway Pilot) system, used to make trucks to maintain a constant speed, driving across the lane and keep a safe distance from the vehicle.
To turn on automatic driving requires two things: first open the HWP, once after the truck on the highway and cruise, cruise control is opened. At this point, took over driving duties of the truck until it encountered bad weather, lost lane information, need to overtake, or highway under it. When you encounter these situations will require humans to take over, means that the system need to be convinced that human beings can take control of the wheel. The A7 auto-drive prototype, test groups in Europe, China and the United States are tested, creating a simple and orderly UI.
When the truck is out of range, the pilot will hear a high-pitched sound, the alerts dashboard flashing for a few seconds, reminding people to take over. If humans did not answer, the system will control the truck stop. Development Inspiration because Daimler is ready for commercial use, so they will continue to improve the system, carried out extensive tests to ensure that humans can answer very well. Now, however, they chose to simplify, as developers put it, "after all, is a 6-month project, sound good enough."
Test
Autopilot in order to obtain Nevada license plates, Daimler's need to prove that the system can safely 10000 miles. Test team in odometer installed on two trucks, plus a test car (uses the same system but no manual), in Germany and Nevada on a quiet road, a road test. In the system prior to the listing, UI also needs to do more testing. This means that traffic engineers make car run good in extreme temperatures, and trudged in the rain and snow, tens of millions of miles to find and fix any flaws they found.
Although it is still at an embryonic stage, the system has shown promise of the trucking industry. Daimler to focus its attention on easier, safer and more effective on the drive. They performed a small test, and 16 drivers on the test car, automatic driving systems affect the driver showed fatigue than you driving to reduce by 25 per cent.
This is important, because when they are drivers to drive more carefully. But it also hides the more potential that, at present, in continuous operation 10 hours later, a truck driver only when driving on the highway for 11 hours. This provision is the United States truck driver a short Board, and the situation is getting worse. United States according to a recent study of the transport sector, freight forwarding company provision of the services as their first concern. If you use automatic driving systems, Daimler can allow drivers to less fatigue, managers may be reluctant to relax rules, soon after the commercialization of the product.
According to Daimler said, many customers very interested in this system. This is not surprising, because the drive to the computer can significantly reduce the rate of accidents, improve fuel efficiency, and can even allow the truck to run on the road for some time. Driver short Board also limits the demand for new trucks, but developed the technology of direct economic stimulus is, if Church truck to drive, Daimler is not only have a high-tech product, it is more of a increased demand for products.
