Was in recently home, produced what tesla brings about because of cannot identifying ahead old freight car one case to chase after end accident, the heat that caused a netizen is discussed.
? And this also is not is tesla first dash against old freight car.
On May 7, 2016, car of Model S of a tesla is driving automatically the travel below mode is when the crossing of a high speed of American Florida city, with ahead the old freight car of left abduct produces collision, caused a tesla car thereby advocate die. This is the whole world the first drive automatically the accident is deadly case. Its reason is to fail to identify an old freight car unexpectedly.
? In January 2018, in American California city, an open is auxiliary drive tesla Model S of the system with 65 miles / the speed travel of the hour, hit the fire engine of a park however, what what I hope is the driver just got flesh wound.
? From 2016 up to now, tesla produced the accident with barge against of old freight car 3 cases at least. Once will " drive automatically " the tesla that the function regards stunt as, why cannot identify even old freight car?
Cannot identify old freight car? Because,be probably " the eye is blind "
Drive automatically simple for, it is perception actually- - identify- - decision-making. Through installation on board the sensor such as radar of camera, millimeter wave, lidar gathers external environment information, then the computer undertakes analyse and discriminating to these information, detect the information such as a road, fraise, pedestrian, car. The computer undertakes according to these information again decision-making.
Other to class of L2, L3 auxiliary drive, often detecting when giving road margin news and car information, can come true to get used to cruise, travel following a car, active brake to wait oneself. And to the L4 level, L5 level that achieves to drive completely automatically even, still need to undertake to all information all round the car modal analysis is mixed dog, in order to answer all sorts of complex cases.
Of course, say simple, but each pace is not actually easy. And tesla cannot identify old freight car, frequent with barge against of old freight car, actually the most possible reason is not probably is to cannot identify, press a root to be done not have however " see " .
Because to old freight car this is planted fraise, even if is pattern recognition layer fails accurate identifying, also can treat its as commonly fraise undertakes avoiding letting. And in the course that tesla is pursueing end tesla, did not have the decelerate, operation such as brake. So, it is tesla drives automatically probably in the system " eye " appeared problem, produced these accidents again and again thereby.
Drive automatically the eye in the system often wait by radar of camera, lidar, millimeter wave will act as, and these sensor are having respective drawback however, for instance camera is in the effect of night is very poor, millimeter wave radar explores distance weak point, lidar suffers environment and weather influence easily to wait. When how terrible of situation of strong light, backlighting, weather, probably these " eye " fluky.
In Everyman acknowledge, feel big to van is probably special the object that distinguishs easily, why of tesla do nobody drive is the system met cannot identify?
E.g. , when these sensor installation positions are inferior, so taller to close quarters fraise is to cannot be explored, if tesla encounters weather to wait for a circumstance badly, by force solely when travel, may make the visual system of tesla loses action, and when travel arrives when distance old freight car is closer, as a result of old freight car taller batholith, and sensor cannot detect again noumenon of taller old freight car, can let a system think ahead does not have an obstacle by accident, thereby direct with barge against of old freight car.
? The road surface information that lidar scanning gets and fraise information
Because,also be such, on the technical program that at present the environment feels, basic upcast abandoned unitary visual system, and the plan that changes much sensor data to confluence, in order to obtain more essence of life follows reliable environmental news.
Besides cannot identify old freight car, drive automatically what to flaw still have?
The tesla that goes in automatic road-sense forward position frequency sends an accident, offend so that everybody suspects in succession, is automatic road-sense reliable really?
Someone says, drive automatically those who depend on still is the computer, computer pilot nature has a risk. Someone says, driving automatically is a trend, no matter the process of its development has how difficult, also cannot stop its pace.
Indeed, tesla is driving automatically on (oneself also change call auxiliary drive) relatively radical, there still is immature place on the technology, because this technology is in,now is not so reliable. The old freight car that links ahead cannot identify, more the complex case when carrying normal drive a vehicle. For instance tesla car advocate often mention, tesla is quickened suddenly on the road by oneself and cannot identify the problem of static fraise.
?
? Of course, although present automatic road-sense is immature reliable, bring about accident frequency hair thereby, make the people right this technology generated suspicion. Nevertheless, the tide that the technology develops resembles historical process occasionally, it is met probably be thwarted decelerate, but ongoing footstep won't stop however. Accordingly, although tesla produces so many safe accident, still also insist to develop and popularize its however automatic road-sense.
? Finally, before hoping everybody has not mature in automatic road-sense, the attempt experiences can, do not trust completely.
