Autonomous car contact accident cause is "system misidentifies" August 29 5:19

As a result of an investigation conducted by Nagoya University on an accident where an autonomous driving vehicle, which had been running in Toyota City, Aichi Prefecture, suddenly moved to the right and contacted a general car on the 26th of this month, the self-driving vehicle system was I found out that there was an accident.

On the 26th of this month, on the city road in Toyota City, Aichi Prefecture, when the driver was driving at 14km / h with the driver not holding the steering wheel, it suddenly moved to the right, so he tried to pass from the right side. I contacted a general car.
There were no injuries.

This self-driving car was developed with a system that measures the distance from buildings with a radius of 150 meters with a radar based on a three-dimensional map that memorizes the driving route and checks the direction of the vehicle. Nagoya University analyzed the data at the time of the accident.

As a result, at that time, it was found that an error occurred when applying actual radar data to the map, and the system incorrectly recognized the direction of travel and turned the steering wheel to the right.

In the future, Nagoya University will set up an accident verification committee with outside experts to investigate the cause of the accident and then consider measures to prevent recurrence.

In response to the accident, Toyota City and other councils have decided to cancel the demonstration experiment that was scheduled to take place on the 29th.
