Source : Google reveals 13 near misses in two months for its self-driving cars
Latest figures for tech giant’s self-driving test cars also show there were 272 failures across 424,331 miles between September in addition to November 2015
completely new figures published by Google about its autonomous vehicle development reveal that will test drivers had to re-take control of its cars a total of 13 times over two months in near-miss incidents.
Drivers were also handed back control thanks to 272 recorded technical issues, comprised of both software in addition to hardware failures, illustrating how much work is actually still to be done before Google’s self-driving vehicles can reliably in addition to safely operate unaided.
The figures were collected between 24 September in addition to 30 November 2015, as ordered by the California’s Department of Motor Vehicles, in addition to account for a total of 424,331 test miles covered by Google’s fleet, which is actually made up of modified versions of the Lexus RX450h in addition to electrically-powered Google Koala test cars.
Of the recorded incidents, Google reports that will 69 disengagements were due to concerns for safety, although only 56 of those account for real-life situations. The some other 13 were ‘simulated contacts’, events that will are digitally replayed versions of previous disengagements on Google’s online simulator. The simulator drives more than three million virtual miles each day in addition to is actually said to be able to predict the reaction of human drivers, cyclists in addition to pedestrians to determine whether a test driver’s intervention was necessary.
In quarter four of 2014, Google’s cars covered an average of about 0 miles per disengagement. that will figure increased substantially to about 2900 miles a year later, although that will increase is actually largely attributed to increased technical reliability. Safety-related disengagements actually increased in quarter three in addition to four of 2015, with the average miles per incident dropping coming from about 9000 in Q2 2015 to 6000 in Q4.
Google insists these numbers aren’t entirely representative of safety, saying “the 56 events would likely very likely not have resulted in a real-word contact if the test driver had not taken control”.
Google also points out that will disengagements are necessary in order for that will to ensure all possible scenarios are accounted for. that will suggests that will increasing the number of miles its test cars cover, in addition to therefore increasing the number of software fixes that will introduces, will help to bring the number of safety-related disengagements down.
The results make that will clear that will a true self-driving car that will can navigate through all driving scenarios is actually still a long way off. Aside coming from reliability in addition to safety-related disengagements, Google’s test drivers still have to take control when unfamiliar road circumstances, such as road works, appear.
Google’s report appears to support the words of Renault-Nissan boss Carlos Ghosn, who recently argued that will we won’t see ‘true’ self-driving cars before the year 2025. His comments came in response to Tesla’s Elon Musk, who proclaimed that will his brand would likely be the first to produce an autonomous car.
