A recent study by the American Automobile Association (AAA), the American Automobile AssociaTIon, shows that carmakers are stuffed with entertainment systems on the dashboard of new cars. But these in-vehicle entertainment systems are driving drivers to risk their long-sighted departures from the road and let their hands loosen the steering wheel. On October 5th, David Strayer, a professor at the University of Utah, released the latest research. Since 2013, Stryer has been working for the American Automobile Association Transportation Safety Foundation to investigate the impact of in-car entertainment systems on driving safety. Although previous studies have found the same problem, Stryer said that the "technical explosion" made the situation worse. Currently, global automakers offer a variety of options that allow drivers to use social media, email and text messages while driving. In the past, the car had only a few buttons and knobs, and now there are as many as 50 multi-function buttons on the steering wheel and dashboard of some cars. For example, touch screens, voice commands, writing pads, head-up displays (HUDs) on windshields, computer-generated 3D images, and the like. Stryer believes that the things that the driver's fingertips can touch are more and more complicated, and the amount of information is increasing, but car manufacturers usually do not consider putting these systems at the touch of the driver. Is not a good idea. Complexity now increases the total time the driver spends using these systems. However, the automotive industry generally believes that these new systems offer drivers a better choice than mobile phones and navigation devices that are not suitable for use in driving. Wade Newton, a spokesperson for the American Automobile Manufacturers Union, said that the car integration system is designed to be used in a driving environment, requiring the same driver's attention as the radio or temperature control, while driving ( Adjusting the radio and adjusting the temperature) has always been considered a generally acceptable behavior. However, Jake Nelson, director of traffic safety advocacy and research at the American Automobile Association, pointed out that tests on 30 cars and light trucks in 2017 showed that when the driver uses the car entertainment system, the line of sight will deviate from the road and the hand will The steering wheel will be released. Because the test driver drives, he uses voice commands, touch screens, and other interactive technologies to make calls, send messages, adjust the radio, or navigate. Obviously, automakers "do not have enough effort" to make the onboard system responsive and easy to use. The researchers believe that 23 of the 30 vehicles tested require drivers to have "very high" or "high" attention. Seven vehicles under test were considered to require "moderately moderate" driver attention. But without a vehicle under test, these systems can be used with less attention from the driver. Planning the destination through the in-vehicle GPS navigation system is the most distracting behavior for the driver, which takes an average of 40 seconds to complete. At a speed of 25 miles per hour, the car can exercise the length of 4 football fields during the time the driver enters a destination. Previous studies have shown that the driver's line of sight is only 2 seconds away from the road and the risk of a collision is doubled. Under industry pressure, the National Highway Traffic Safety Administration (NHTSA) issued voluntary safety guidelines for dashboard technology to automakers in 2012, rather than mandatory safety standards. The guidelines recommend that car manufacturers improve the ability to lock navigation systems while the vehicle is in motion. However, in the study, the navigation system was rewritten during the driving of 12 cars. The guidelines also recommend that car manufacturers prevent drivers from sending information while driving, but three-quarters of the vehicles tested allow the driver to send information while the vehicle is moving. The ability to send information is the second most distracting driver's attention. In China, this phenomenon is particularly serious because of the rise of WeChat. Even when the voice command is used, the driver's line of sight deviates from the road time, but as the driver interacts with the vehicle system for a longer period of time, the safety performance will be degraded. According to the American Automobile Association, drivers can only use in-vehicle technology systems in a reasonable emergency or for urgent, driving-related purposes. The association also urges automakers to lock in the ability of the navigation system and the ability to send information while the vehicle is in motion; automakers should also redesign the in-car entertainment system to achieve the attention of using these systems, no more than listening to the radio or sound The attention required by the reading. According to a poll conducted by the American Automobile Association, almost 70% of American adults said they would like to install these new technologies on their vehicles. But only 24% believe that these technologies are working perfectly. Marshall Doney, president and CEO of the American Automobile Association, believes that drivers want to use safe and easy-to-use technology, but many of the features added to in-car entertainment systems have led to over-complexity and sometimes reduced drivers. User experience. Compared with the United States, this is why Chinese consumers prefer to use mobile phones instead of in-vehicle systems during driving. But with the development of artificial intelligence and technology, and the development of assisted driving and driverless driving, it is not a matter of time to “fill up†the technology in the car.
Pentagonal prism is one of the beam steering devices with fixed angle (90 °). It has two purposes: first, the outgoing light turns the incident light to a certain angle (90 °) regardless of the incident angle on the first side; Second, unlike a right angle prism, its image has neither rotation nor specular reflection. Pentaprism is commonly used in camera viewfinder, image observation system or measuring instrument.
