Self-Driving Cars
The current state of self-driving cars separated by technology. Self-driving cars, which travel safely without a driver, are a dream technology.
Nowadays, automakers and IT companies are also getting into the development of independent driving technologies. However, cars that drive automatically will not emerge as soon as people do not drive at all. It will take a long time for fully independent vehicles to be used in practice.
In Japan, self-driving cars are categorized from level 0 to level 5 according to technology installed according to the definition of SAE (International Society of Automotive Engineers of Japan). Gradually they aim to improve and implement the use of advanced independent vehicles.
In the category of self-driving cars, level 0 is defined as no automatic driving technology, level 1 is defined as driving assistance, level 2 is defined as automatic driving, level 3 conditional driving, level 4 is advanced. For automatic driving, level 5 is defined as fully automatic driving.
Independent driving level
quality Overview of vehicles equipped with changing driving technology.
Level 0 No independent driving technology Speed / deceleration, steering operation, and all functions are performed at the driver’s discretion. driver
Level 1 With Auxiliary Driving Technology Vehicles equipped with automated accelerator / brake or steering technology. driver
Level 2 Automatic Driver Automotive A supportive driving vehicle equipped with low-speed accelerator / brake performance and steering wheel operation.
Level 3 Conditional Driving Conditions A car with technology that performs all driving operations under certain conditions. However, even if the automation system is working, the driver should be able to return to operation at any time upon request. Driver if operating system is difficult
Level 4 Automatic Automatic Driving A car with technology that performs all driving operations under certain conditions. system
Level 5 Automatic Operating A car fitted with a technology that performs all driving operations unconditionally.
There are two major approaches to independent driving research. One is ABS (Antilock Brake). Stability management technology such as Strength System) and VSC (Vehicle Stability) Control) and safety measures such as car distance maintenance system, cross-sectional prevention system, and collision prevention system have developed to lead to independent driving. It can also be rewritten from the foot to the head “.
Another move for advanced AI technology and recognition technicians who use those technologies in cars, saying, “Cars are hot from now on.” In other words, this “walk down from the head of the car to your feet.
Is there a certain “safety” level for this private drive?
Sometimes I hear expressions like ‘private driving system is safer than human driving, but at the moment it’s hard to make a rational explanation to say that. security is still under construction, and the “obvious” state of affairs so far is “do not hit pedestrians, other vehicles or obstacles”.
last independent mile driving
“The last mile of private connectivity ” includes travel areas such as train stations and bus stops, specific infrastructure such as hospitals and shops, and residential areas where people live independently without private driving.
We do a lot of demonstration tests in different places, but we usually notice it for the first time after trying it. For example, you need a well-maintained road to drive a car. When you actually drive a private car on a public road, you realize its value too. Roads deteriorate over the years, and some areas require weed in summer and snow in winter. Vehicles are able to drive on the roads because local governments and local people work on road maintenance. With that in mind, as the age and population diminish, you may need to think first about driving independently for road maintenance.
