Current status of autonomous driving technology
Self-driving technology has made remarkable progress in recent years, and many automakers and tech companies are racing to develop it. Currently, what is being put into practical use in the general market is mainly the autonomous driving function called “Level 2” or “Level 3” in some cases. These systems assist and take over steering operations and acceleration/deceleration under specific conditions such as on expressways.
However, the road to fully automated driving (Level 5) is still a long way off, and various challenges stand in the way. In addition to technical barriers, it is essential to develop laws, adapt infrastructure, and above all, improve social acceptability. For example, progress is being made in improving the recognition accuracy of sensors and strengthening AI’s predictive ability, but further technological innovation is required to ensure safety during bad weather and in complex urban areas.
Main challenges for popularization
One of the biggest challenges for the full-scale spread of autonomous driving is “improving the legal system.” There is an urgent need to enact legislation that will clarify who is responsible in the event of an accident (whether it is the driver or the system manufacturer). Although discussions are underway in each country, there is also a need for unification of international standards.
Ensuring cybersecurity is also extremely important. Since self-driving cars are ``connected cars’’ that are constantly connected to external networks, strong security measures are essential to deal with risks such as remote control due to hacking.
Another challenge is communication with pedestrians and other drivers. Technological and ergonomic approaches are being researched, such as interface designs that can replace human eye contact and gestures to communicate the vehicle’s intentions to its surroundings. In order for autonomous driving technology to fully integrate into society, it is necessary to overcome each of these multifaceted issues one by one.
