We will explain the below topics here.

1. What is Autonomous Driving ?

Autonomous Driving means "a system that performs autonomously without relying on people to handle vehicles or moving bodies".​ ​

In recent times Autonomous Driving has been a common topic in the articles.

If autonomous driving is put into practical use, it is a technology used as a safe and comfortable means of transportation, where an autonomous car reduces accidents and traffic congestion and takes you to the destination without the driver's operation. Currently, many cars are beginning to sell with some of their automated driving features. Autonomous Driving technology that evolves in harmony with the traffic environment.

Here we will introduce the history of Autonomous Driving, the level of Autonomous Driving control currently defined in the industry, and the state of legal maintenance.

2. History of Autonomous Driving

Research on automation of robots and moving bodies has been on for a long time.
In the 1900's, it seems that the idea of "turning automobile into automated driving" appeared from about the time the car began to be used even in general.

In Japan, self-driving cars designed for driving on the road were developed in 1977 by Prof. Toshiyuki Tsukawa of the Mechanical Technology Research Laboratory in Tsukuba. In 1980, Mercedes in Germany was also actively working on the development of Autonomous Driving technology.

Since then, research has been conducted on autonomous mobility at each university, and in 2004, sponsored by DARPA (National Defense Advanced Research Projects Agency) the Autonomous Driving car contest "DARPA Grand Challenge" was held.

We designed and sold conventional biped walking robot and home entertainment robot and for the future we started to utilize this robot technology to steer up the development of Autonomous Driving technique which is required socially.

ZMP launched the first robot car "RoboCar 1 / 10" in 2009.
In 2010, we released real-type robot cars "RoboCar HV" and "RoboCar Minivan".

Currently automakers and IT makers, venture companies are working on development aiming at practical use of Autonomous vehicles, and development competition is intensifying.

ZMP took part in the TOKYO MOTOR SHOW which was held in 2013, we carried out the RoboCar test drive session and later according to the guidelines, we started the demonstration tests on public roads. In 2020, we are promoting development the to start Auto taxi service.

3. Autonomous Driving level and definition

SAE International (Society of Automotive Engineers) published the classification system for the six different levels in 2014, updating in 2016 and 2018 titled "Taxonomy and Definitions for Terms Related to Driving Automation Systems for On-Road Motor Vehicles"and JASO TP 180043 (February 2018), which is a Japanese reference translation.

What is SAE (Society of Automotive Engineers)?
SAE International is a global association of more than 128,000 engineers and related technical experts in the aerospace, automotive and commercial-vehicle industries,
and their core competencies are life-long learning and voluntary consensus standards development.
As of 2006, it is an organization with 90,000 members from 100 countries.

Autonomous Driving level

There are six levels of Autonomous Driving in the SAE's classification system, ranging from level 0 to level 5.

Who will take responsibility when an autonomous car causes an accident? There is a concern that there is currently a division between levels 2 and 3.

Autonomous Driving Up to level 2 is positioned as driving support, and the "driver" is responsible for the accident,
Autonomous Driving Level 3 or higher Autonomous Driving is positioned as "Autonomous Driving" hence the Autonomous Driving system is responsible for the accident.

Currently, up to level 2 is adopted for commercial vehicles in Japan, and its commercialization is in progress.
The ADAS technology currently installed is the function to support the driver to the last and the responsibility in case of an accident is on the driver side.

On the other hand, it is said that the responsibility for accidents is on the side of automated driving systems (cars) when it is level 3 and higher because it doesnt involve drivers operation.

Even with ZMP Autonomous Driving Driving tests are conducted by a level 3 equivalent system so that the driver can get in and the driver can take over the operation when it is abnormal, but in the current legal maintenance, such Autonomous Driving When driving a vehicle, it is a situation where the driver needs to take his own responsibility.

Therefore, commercialization at level 3 or higher of automated driving requires the development of laws (such as clarification of responsibility in case of accidents) and the development of infrastructure, with a focus on the government.

The details of the levels of Autonomous Driving are explained below.

4. Legal maintenance of Autonomous Driving

The Government of Japan is aiming to commercialize Level 4 that is Level 3 with expressways and Level 4 fully automated driving within a limited area by Tokyo Olympics 2020, and legal development of the law regarding Autonomous driving is currently underway in Japan as well.​ ​

On March 8, 2019, we revised the Road Traffic Act (the Road Traffic Act) and the Road Transport Vehicle Act.
Drivers are still necessary in level 3 cars, but are able to completely shift "safety-critical functions" to the vehicle, under certain traffic or environmental conditions. It means that the driver is still present and will intervene if necessary, but is not required to monitor the situation in the same way it does for the previous levels.

Therefore, it may be safe to do other things while driving with the automatic driving system, How well the system takes over, and whether there were no problems in taking over the system in the event of an accident, it may be difficult to draw the responsibility between the car manufacturer and the driver.

For this reason, some manufacturers have argued that it would be realistic for practical use to go ahead with a self-driving system with Level 2 and Level 4 pillars.

In addition, even if the technology of automatic driving has been developed, it is considered difficult to widely spread the technology of automatic driving unless social acceptability and legal issues are solved.

· Social acceptability

Here, we introduce "How fully automated cars are taken by people".

The social acceptability of fully Autonomous Driving vehicles differs from country to country.
According to the data from 2017, the number of consumers who feel "unsafe" in Japan is comparatively low when compared to the consumers in China.

ZMP continues its demonstration tests to improve the social acceptability of Autonomous Driving.

We carried out the first Autonomous Driving taxi service trials which is to be the first one in the world from 27th August to 8th September 2018 and the route was from Otemachi to Roppongi.

One of the customers who has ridden the car commented that, the sensor mounted vehicle gave us a safe and ease ride. Even though I was tensed in the beginning, I felt like I was riding a normal car only.

Various approaches are necessary for running automated vehicles in society and it is necessary to continue working on it from now on.

Along with the improvement of the technology and social acceptance of Autonomous Driving, another matter to be resolved is concerning legal maintenance.

In addition, not only legal maintenance but also traffic rules and enlightenment activities for vehicles driven by people and self-driving vehicles, insurance and guarantees in case of accidents, etc. There are various items to be addressed in order to realize the driving society.

In particular, in the case of Autonomous Driving the topic of the trolley problem is discussed.Whether an Autonomous vehicle be sacrificed at the expense of the passenger if the accident becomes inevitable, or should the pedestrian's life be protected or the passenger rather than the pedestrian, should we give priority to life? There are also cases where the control algorithm needs to be considered ethically.

Research on the "trolley problem" of Autonomous vehicles, to save whose life is going on.
