Şunun için etiket arşivi: robotaxi crash

Zoox, the self-driving vehicle subsidiary of Amazon, has agreed to recall 270 autonomous vehicles following an April 8 crash in Las Vegas involving one of its unoccupied robotaxis and a passenger car. No injuries were reported, but the incident prompted a temporary suspension of operations and a subsequent software update to correct the issue.

According to Zoox, the crash occurred when the robotaxi misjudged a perpendicular vehicle’s behavior, incorrectly anticipating that the oncoming car would continue moving. Instead, the car stopped and yielded, but the Zoox vehicle had already slowed and shifted right, leading to a collision despite hard braking.

The company identified that the issue arises when its vehicles travel at over 40 mph (64 km/h) and encounter vehicles that slowly encroach from perpendicular driveways. The system’s failure to accurately predict the yielding vehicle’s stop was the root cause of the incident.

Zoox has since rolled out a software fix to prevent similar errors and stated that the vehicle behavior has been addressed. This marks the second recall in recent months: in April, the National Highway Traffic Safety Administration (NHTSA) closed a probe into 258 Zoox vehicles following two rear-end collisions caused by unexpected braking, after Zoox issued a software update.

However, Zoox remains under NHTSA scrutiny. The agency is still investigating the company’s 2022 self-certification of a robotaxi without traditional controls, such as a steering wheel or pedals.

The incident underscores ongoing regulatory and technical hurdles faced by autonomous vehicle developers as they approach broader deployment.
