Tesla driving data decrypted by the Dutch Institute of Forensic Medicine

London — The Dutch Government’s Forensic Institute said Thursday that it had deciphered an electric car maker Tesla A tightly guarded driving data storage system reveals a wealth of information that can be used to investigate serious accidents.

It was already known that Tesla’s car stored accident data, but the Dutch Institute for Forensic Medicine (NFI) said it found far more data than the investigators knew before. I did.

According to the NFI, the decrypted data shows that Tesla’s vehicle stores information about the operation of a driver assistance system known as the autopilot.The vehicle has speed, accelerator pedal position, steering wheel angle, and break Depending on how you use it and how you use your vehicle, that data can be stored for more than a year.

“These data contain a wealth of information for forensic researchers. Traffic accident We are an analyst and can assist in criminal investigations after a fatal road or injury accident, “said Francis Hoogendijk, a digital investigator at NFI, in a statement.

Tesla did not immediately respond to the request for comment.

Instead of looking for data in Tesla, Dutch laboratories put “reverse-engineered” data logs (the process of disassembling software to extract information) into Tesla’s vehicles “for objective investigation.” Said it exists.

‘Who is responsible? ‘

NFI investigated a collision between a Tesla driver using an autopilot and a car in front of him suddenly braking hard.

As a result of the investigation, Tesla’s driver responded to the warning to regain control of the car within the expected response time, but a collision occurred because Tesla chased too many other vehicles in crowded traffic.

“That’s interesting, because who is responsible for the next distance? Is it a car or a driver?” Said NFI investigator Aart Spek.

According to NFI, Tesla encrypts coded driving data to protect technology from other manufacturers and protect driver privacy. Car owners can request data, including camera footage, in the event of an accident.

Earlier this year, Tesla said it set up a site for China To store vehicle data locally as automakers are increasingly overseen how they process the information collected by vehicle cameras and sensors.

Decryption reveals more data

The NFI found that Tesla complies with data requests from Dutch authorities, but ruled out a lot of data that could prove useful.

“But Tesla provides only a specific subset of the signals, only as requested, in a specific time frame, but the log file contains all the signals recorded,” the NFI report said. Stated.

Decrypting Tesla’s code will give NFI a more accurate picture of the type and duration of data stored by automakers, allowing for more detailed data requests, Hoogendijk said.

“I can’t claim what I don’t know, so it would be great if I could find out what else was preserved,” he said.

Hoogendijk added that this also applies to other automakers. Investigators don’t know how much, what kind of data the data maker is storing, or how long it is.

The lab said Tesla could access the data remotely. This data is regularly uploaded from the car and used by the company to improve the product and fix malfunctions.

NFI said it obtained data from the Tesla Models S, Y, X and the mass market. Model 3 We then shared the results at a meeting of the European Accident Research Association so that other accident analysts could use it.

August, usa National Highway Traffic Safety Bureau (((NHTSAAfter a series of clashes involving Tesla models and emergency vehicles, 765,000 US vehicles have begun a formal safety investigation into Tesla’s autopilot system.

To date, NHTSA has identified 12 collisions related to Tesla vehicles using advanced driver assistance systems and emergency vehicles. NHTSA said most of the incidents happened after dark.
