Demonstration experiment of automatic driving Sensor performance decreases during bad weather 19:10 on November 22, MLIT
The Ministry of Land, Infrastructure, Transport and Tourism analyzed nationwide demonstration tests on automatic driving of cars, and found problems such as sensor performance degradation during bad weather.
The Ministry of Land, Infrastructure, Transport and Tourism and private enterprises have conducted automated driving demonstration experiments so far, and analyzed the results and summarized the issues of autonomous driving.
As a result, the problem is that the sensor of the self-driving car deteriorates in bad weather such as heavy fog and snowfall, and the accuracy of GPS necessary for driving the self-driving car falls in the mountainous area.
In addition, as a countermeasure, it is planned to embed magnetic markers etc. on the road to supplement the accuracy of sensors and GPS to make it easier to grasp the position of the car, and to consider restrictions on the environment that can be run such as not operating in bad weather The
On the other hand, we decided to consider expanding the number of vehicles that can be monitored by one person in charge from one to two to three or more when performing a mobile service for autonomous driving.
