Google's automatic driving car drives 4.8 million km daily in virtual space and checks safety

Google to develop an automatic driving carStart public road running test from 2015We are testing to see if we can travel safely according to actual traffic rules. However, Google fully utilizes the capabilities of its own data center and makes "running" a tremendous distance of 3 million miles (about 4.8 million kilometers) every day.

According to Google's announcement of utilization to the automatic driving car of the data center, driving simulation of the automatic driving car is carried out every day at Google's data center, simulating the actual public road running and obtaining it from there The result is reflected in the test running vehicle.

In the simulation, it seems that the 3,000,000 miles (about 4.8 million kilometers) per day, the actual distance of 120 laps of the earth, the automatic driving car will "run" on the public road in the virtual space, the place of traveling is not only the highway, Various situations are envisioned, including. In the United States, the car seems to have traveled 2.7 trillion mile (about 4.3 trillion kilometers) in 2000 alone even in a single year, and in order to guarantee safety it is equivalent to the total distance traveled by all cars We believe we should test.


Then, before the new technical change is tested on the actual run, the simulation is used to carry out the virtual running experiment with the program applied beforehand, and the safety and effectiveness are checked . Only the promising technology which passed through this check is tried on actual driving. 22 Lexus RX 450h and 33 unitsOriginal prototype without handle pedalSimulation has been applied to all of the change programs, it seems that it is the condition of employment in the actual driving test to clear the running test of more than 2 million miles (about 3.2 million kilometers).

A promising program which cleared the riding test of a ridiculous distance is reflected in the actual automatic driving car and it is reflected in 10,000 miles (about 16,000 kilometers) to 15,000 miles (about 24,000 kilometers) in a week, It is said that the actual running test is being carried out.

In addition, Google has a plan to expand the roads of public roads started in Mountain View, California, to cities across the United States, such as being conducted in Austin, Texas. It seems that they are using virtual simulation tests to remember signals and traffic signs that vary from state to automated driving car.


Google's proud artificial intelligence deep learning is used to discover promising algorithms, and the rise in artificial intelligence technology seems to be directly linked to the improvement of the safety of automatic driving cars.
