U.S. government regulatory agency The company is investigating Tesla’s autopilot system after a car using this feature hits a stopped emergency vehicle.

National Highway Transportation Safety Administration Announce Monday’s survey included 765,000 Teslas sold in the United States, which accounted for a large portion of all the company’s sales in the country. The agency stated that the investigation will cover 11 crashes since 2018; 17 people were injured in the crash and 1 person died.

NHTSA is studying Tesla’s entire product line, including Model S, X, 3 and Y from 2014 to 2021. It is investigating Autopilot and Traffic Aware Cruise Control, which is a subset of Autopilot, which does not guide the vehicle but allows it to match the traffic speed.

In these 11 car accidents, Tesla has been hit First responder’s vehicle Vehicles that have been parked and marked with flashing lights, flares, illuminated arrow boards, or road cones.

The survey will cover the entire scope of the Autopilot system, including how it monitors and enhances driver’s attention and participation, and how the system detects and responds to objects and events on or near the road.

Tesla Under review for the way Autopilot verifies the driver’s attention when the system is turned on.In the evaluation of advanced driver assistance systems (ADAS), Autopilot won Medium score In the European New Car Evaluation Program. The system was hampered by its relative inability to keep drivers in touch with the road.

Like many other ADAS systems, Autopilot requires the driver to place his hands on the steering wheel, although placing a heavy object on one of the steering wheel spokes can easily be fooled.A recent survey Car and driver It was found that when the driver removed his hand from the steering wheel, it took 25 to 40 seconds for the vehicle to issue a warning, depending on the model. If the driver does not respond, the car will drive for another 30 seconds before starting to brake. At high speeds, this can cause the system to operate without the driver’s participation up to a mile.

After a car accident in California in January 2018, the National Transportation Safety Board criticized Tesla for trying to keep drivers involved.In there eventAs part of the NHTSA investigation, a 2014 Model S rear-ended a fire truck on the high-occupied lane of Interstate 405 in Culver City. The Tesla driver activated the autopilot and followed another car in the HOV lane, when the leading vehicle changed lanes to avoid the parked fire truck.The autopilot did not turn or brake, the driver Eating bagels, Did not control the vehicle. According to the accident report, Tesla hit a fire truck at a speed of 31 miles per hour.

The NTSB stated that “due to inattention and excessive reliance on the vehicle’s advanced driver assistance systems,” driver inattention may be the cause of the crash. Tesla Autopilot is designed to allow the driver to disengage from the driving task; and the driver to use the system in a way that is inconsistent with the manufacturer’s instructions and warnings. “

Tesla recently started to change the way Autopilot works, Abandon the radar sensor Support additional cameras in Model 3 and Y. (Model S and X will retain radar for the foreseeable future.) As part of the collision display of NHTSA detection, radar data does not guarantee that the ADAS system can correctly sense obstacles on the road, but usually, additional sensors can help the system obtain The complete picture of the scene.Because radar and Lidar Data is essentially a series of measurements that help determine the distance between the vehicle and the object. Although ADAS systems can obtain the same information from camera images, they require more complex calculations than radar or lidar. It is not clear whether NHTSA’s investigation includes Tesla’s new camera-only models.

It is also unclear whether the investigation will affect Tesla’s so-called fully autonomous driving function, a beta version of the function has been released to a group of drivers. The operating video of the system shows that it is a work in progress to a large extent and requires the driver’s constant attention.
