Smart car research and development hatchback craze
Added:2018-06-28     Views:

Russia's World Cup 2018 in combat, the size of the World Cup advertising market company also attracted a lot of attention, in which several car companies gain publicity function such as automatic driving, including new power enterprise established car companies and building cars.

Industry insiders believe that autonomous electric taxis are the main mode of urban travel in the future. However, the securities times reporter in "GIV2018 global smart car front summit" learned, intelligent driving technology there are many uncertainties, achieve the goal of liberation hands, feet, and even the eyes still have a long way to go, need systemic strengthen in roadside facilities and other aspects.

Under the strong promotion of IT technology, a new round of research and development upsurge has been launched in intelligent vehicle technology. "Autonomous driving will revolutionize and revolutionize the road traffic system and have a huge impact on traffic safety." The ministry of public security traffic management science research institute, deputy director of the hanzhong, said pan self-driving cars is equivalent to the original human bicycle, carriage era into a stage of auto society, it is also the world attaches great importance to the main reason of the automatic driving safety test.

But autonomous driving is fraught with uncertainty. Gao yongqiang, huawei's director of automotive networking standards, said that in March, Uber's self-driving cars in the United States killed pedestrians. 6 seconds, according to the official report a car accident before driving system has identified target pedestrians, but the pedestrian recognition as an unknown object first, and then identified as a car, and recognized as a bicycle, in front of the car accident, a second system remind need brakes to avoid traffic accident, but the system did not perform.

The reporter understands that there are two aspects of false alarm and false alarm in the information of automatic driving. Once it is far away from false alarm, it may leak, so it is difficult to balance. For one thing, it may cause the vehicle to brake suddenly, causing the vehicle to lose control. In order to prevent false alarm, the automatic drive system sometimes filters out the target, but it is hard to avoid the typical case of missing alarm that will cause the accident.

In terms of preventing traffic accidents, a smart car will need about 10 billion miles of test range before it can hit the road. This level of public road test costs is unacceptable to any business. Xiong lu, deputy director of tongji university's new energy automobile engineering center, said: "the test cannot be fully covered, there are scenes of endless roads, and the test is incomplete." So, public road tests have limitations, need in the limited test smart car in the scene, therefore derive a series of dangerous scene extract technology, virtual test technology and accelerating test technology.

Mr Gao said that compared with autonomous driving, communication is just a system with high certainty, and more control over vehicle driving could be handed over to roadside facilities in the future. To be specific, first of all, you can push the cooperation between the vehicle and the road, and send the signal lights to the car. There are also some dangerous roads and dangerous weather information that can be sent to the car. Second consider open after the first roads, road, such as the first consider highways or the city's main road, the road condition is relatively simple, roadside facilities deployment is also easier, after gradually to ordinary roads, into a more complex road conditions. Moreover, autonomous driving can be extended from operating vehicles to passenger vehicles, such as trucks and long-distance buses, as well as some park buses and buses, and then consider the large number of private cars.

It is also a solution to the above problems, and has been used in Beijing - tianjin high-speed railway, guangzhou metro and some expressways. New coastline company vice President Mr Leven thinks, from the bicycle to combat mode transition to the road together, including between car and car, car and road, through a dedicated wireless communication technology, realize the reliable and real-time information interaction. Information may include every vehicle information such as position, velocity, acceleration, steering, through wireless communication to do this kind of information interaction, not affected by the weather, is not affected by shade, and a greater range.
