Tesla Autopilot: 830,000 cars under investigation in the US, possible recall

Approximately 830,000 Tesla have been investigated by the Nhtsa, the American traffic safety authority. The house founded by Elon Musk could be asked to execute a recall. At the base are the difficulties on the part of Autopilot to recognize a vehicle in an emergency stop

The Nhtsa, the American traffic safety agency, last fall opened an investigation into Tesla’s Autopilot, asking for more information from the American company and is now deepening its investigation with an engineering analysis that could lead to a recall. The problem under investigation is the way in which Tesla’s driver assistance software identifies vehicles in emergency stop, stopped with the four arrows activated, and the way in which the Autopilot warns drivers of imminent danger. As reported by the National Highway Traffic Safety Administration (Nhtsa) over 830,000 vehicles are potentially affected, including Model S built between 2014 and 2021, Model X (2015-2021), Model 3 (2018-2021) and Model Y (2020-2021).

the American agency deepens the investigation

There National Highway Traffic Safety Administration will take a deeper look at how Tesla vehicles equipped with the so-called Autopilot driver assistance software behave when confronted with emergency parked vehicles at the scene of a collision. The NHTSA last week said it is updating the preliminary assessment started last August in an engineering analysis, the next step for an eventual recall of hundreds of thousands of Tesla vehicles. In the note released, the federal agency said it was motivated to improve the state of the investigation due to “an accumulation of accidents in which Tesla vehicles, operating with Autopilot on, collided with vehicles stopped on the road or vehicles of prompt intervention intervened on pre-existing collision scenes “. Nhtsa said Tesla itself defines Autopilot as “a level 2 driving automation system designed to support and assist the driver,” and many automakers are using some sort of level 2 system in their new vehicles. Indeed, as part of the investigation conducted last fall, the NHTSA asked Tesla and a dozen other automakers to provide information on the operation of their Level 2 systems.

The analyzes of the nhtsa

The US agency followed up on the request for information that took place last August with a request for further information in October and, specifically, on the way in which Tesla makes changes to the Autopilot using updates. over-the-air and how Tesla requests to enter into nondisclosure agreements with owners whose vehicles are part of Tesla’s so-called “beta” release program Full Self-Driving (Fsd). Despite the name, the FSD is not actually capable of driving the car on its own. The NHTSA said of investigating 16 incidents so far and found that Autopilot stopped controlling the vehicle, on average, “less than a second before first impact”, although videos from these events showed that the driver would be able to see the potential crash on average eight seconds before impact. The agency then found that most of the drivers had their hands on the wheel (as requested by Autopilot), but nevertheless did not have time to take evasive action. In four of the incidents, or 25%, Tesla did not issue any “visual or audible warnings during the last Autopilot use cycle.” NHTSA is also looking into another 100 Tesla incidents that used Autopilot but did not involve first aid vehicles. Preliminary examination of these accidents shows that in many cases the driver was “not responsive enough to the demands of dynamic driving”. For this reason, the NHTSA will use its survey to evaluate “the technologies and methods used by Tesla to monitor, assist and monitor the driver’s attention in dynamic driving during the operation of the Autopilot system”.

even phantom braking

The investigation into Autopilot and the impact on emergency stop vehicles is separate from another recent NHTSA initiative, which asked Tesla for more information on “phantom braking” caused by automatic braking systems. emergency (A and b) of the company. The company has until June 20 to submit documents relating to the hundreds of reported Aeb problems to Tesla.
