in fatal Model S crash Updated
On Tuesday the National Transportation Safety Board met to discuss 2016′s fatal Tesla Model S crash in Florida. NTSB did not have any major new findings beyond those we reported in June, nor did its findings coque samsung a3 2016 humoristique differ from a National Traffic Highway Safety Administration investigation into the event. coque huawei pro At this point the facts are clear: Joshua Brown was overly reliant on Tesla’s Autopilot function and interacted with the car only seven times in 37 minutes while traveling at 74mph.
The crash occurred on May 7, 2016, on US Highway 27A near Williston, Florida. The road in question is a four lane highway with coque integrale iphone xs max transparente the eastbound and westbound lanes separated by a grass median, but it’s important to note that it is not a controlled access or divided highway. coque iphone 4 As Brown was traveling east, he failed to notice a tractor trailer making a left hand turn across his path onto a personnalisé coque samsung galaxy j5 side road, and the truck driver failed to yield to the oncoming car. The Tesla hit the trailer roughly in its middle, a collision that sheared the roof from the electric vehicle, which continued another 300 feet (91m) down the road coque samsung galaxy s5 croco before slamming into a utility pole coque samsung galxy ace and coming to rest a further 50 feet (15m) in someone’s front yard.
As NHTSA found, the Automatic Emergency Braking feature on the Tesla in common with just about every other AEB fitted to other makes coque samsung 10 + of cars was not designed in such a way that it could have saved Brown’s life. coque iphone xs The machine learning algorithms that underpin AEB systems have only been trained to recognize the rear of other vehicles, not profiles coque samsung a5 6 personnalisable or other aspects. coque huawei pro The NTSB report did find that a Vehicle to Vehicle communication system (V2V) could have alerted both vehicles to the potential danger, but as we have ad nauseam, V2V is coque iphone xs antichoc 360 still absent from new cars even though the spec is almost 20 years old.
Operational design was a problem
Brown was driving a 2015 Model S, using the original Mobileye sourced hardware and running Tesla’s Firmware 7.1. Although that system batterie coque samsung galaxy s4 works like most other coque samsung j5 swag adaptive cruise coque iphone xs max ol control and lane keeping “Level 2″ semi autonomous driving systems offered by other OEMs, Tesla’s Autopilot differs in that it allowed the driver to go much, much longer without interacting with the car. The industry standard allows for just 15 seconds before it prompts the driver to interact with the vehicle fail to do so and the car stops controlling the brakes, accelerator, and steering. Autopilot, on the other hand, allows for several minutes to pass between prompting the driver, and NTSB’s data reconstruction showed there was no driver interaction for two minutes leading up to coque samsung pour galaxy s7 edge the crash. (Driver interaction in this case is measured by a steering wheel torque sensor.)
Level 2 systems like Autopilot are not meant to replace a human driver; although they will handle the steering and acceleration and braking of the vehicle, the human driver is responsible for situational awareness at all times. coque iphone xr Since the fatal crash, Tesla has modified Autopilot. coque samsung a8 coque huawei p30 The relationship with Mobileye broke down, and Tesla is now developing its own sensor suite coque samsung cover 3 (HW2) and software (AP2), which has yet to reach the same level of functionality as its earlier cars.

Tesla has repeatedly tweaked the operating conditions of Autopilot in response to drivers “doing crazy things.” Now, instead of just giving the driver warnings every few minutes with coque iphone xs max mauve no other action, Autopilot will disable after three ignored prompts within an hour. However, even with the most recent firmware, its cars will still let drivers go between one and threeminutes without human interaction when traveling above meilleure coque samsung j5 45mph sufficient time for Brown’s crash to have happened. We should coque samsung galaxy core prime fairy tail note that Tesla’s instruction manual does tell owners that Autopilot requires the human driver to be ready to take over control at any time, and the company has repeatedly stressed that Autopilot is not meant to be a self driving system coque iphone xs slim transparente when asked about this crash or other misuse of Autopilot.
The NTSB findings include noting that “steering wheel torque is a poor surrogate measure for driver engagement,” and it is telling that all of the Level 3 systems that Ars has seen involve some form of driver facing camera and gaze tracking to monitor driver awareness. coque samsung a7 Additionally, these level 3 cars which are designed for lengthy periods coque samsung galxy j1 2016 of coque samsung mandala driver inattention are geofenced such that they will only work on divided lane highways where an accident like this one would not be possible. (Both safety featuresare also truefor Cadillac’s new Super Cruise system.) Finally, this specific problem confusion over whether a human or machine is in control is the reason why some car makers have decided to skip level 3 automation entirely. We appreciate the NTSB’s analysis of last year’s tragic accident coque samsung galaxy ace 4 orange and we will evaluate their recommendations as we continue to evolve our technology. coque huawei p9 coque samsung a10 We will also continue to be extremely clear with current and potential coque samsung galaxy core prime liberty customers that Autopilot is not a fully self driving technology and drivers need to remain attentive at all times.”
