Chip cha Tesla cha autopilot chayamba kale kupanga, monga adanenera mkulu wa kampaniyo, Elon Musk. Purosesa yomwe ikubwera ikufuna kuti ilowe m'malo mwa nsanja yomwe ilipo m'magalimoto omwe adayamba kutumiza mu Okutobala 2016, ndipo idapangidwa kuti ipereke magwiridwe antchito okwanira kuti asonkhanitse deta kuchokera ku masensa omwe alipo ndikuthandizira kuyendetsa mokhazikika popanda thandizo la driver.
"Kwa kompyuta ya Tesla yomwe imathandizira kuyendetsa modziyimira pawokha ndipo ikupangidwa kale, ntchito yotereyi idzangonyamula 5% yokha ya mphamvu zonse zapakompyuta ndi 10% yokhala ndi redundancy yayikulu yodalirika," adatero Bambo Musk pa Twitter, poyankha kanema. momwe eni ake amadabwa ndi mawonekedwe atsopano a Navigate pa Autopilot, omwe amalola galimoto kuti ituluke mumsewu waukulu bwino, komabe imafuna kuti dalaivala akhalebe ndi chidwi chonse.
Ndilo gawo lalikulu kwa kampaniyo, yomwe yalonjeza kuti pamapeto pake ibweretsa magalimoto odziyimira pawokha pamagalimoto onse aposachedwa a Tesla. Elon Musk akuti "Hardware 2" yomwe ilipo, yomwe ili ndi makamera asanu ndi atatu, masensa akupanga ndi zolandila GPS, ndizokwanira kuyendetsa galimoto mosasunthika pambuyo pake pakukula kwa Autopilot, ngakhale opikisana nawo ngati Waymo amadalira machitidwe owunikira zachilengedwe pogwiritsa ntchito lidar. Pamsonkhano wopereka malipoti mu Ogasiti 8, Tesla adalengeza koyamba nsanja yake, yomwe idzalowe m'malo mwa NVIDIA Drive PX2018. Mu Okutobala 2, Bambo Musk adati chip chidzawonekera m'magalimoto onse opanga zatsopano zamakampani pafupifupi miyezi isanu ndi umodzi.
Zamagetsi ndi gawo la phukusi lomwe Tesla amatcha "Hardware 3." Pofika nthawi yolengeza, kampaniyo inali itapanga kale chip kwa zaka zitatu - ntchito yomwe idapatsidwa gulu lotsogozedwa ndi wopanga mapulogalamu a iPhone 5S a Pete Bannon. Chipchi chapangidwa kuti chifulumizitse neural network yomwe ili pansi pa autopilot.
Ngakhale nsanja yaposachedwa ya Drive PX2 imatha kugwira mafelemu 20 pamphindikati, Tesla akuti yankho lake limatha kugwira mafelemu 2000 okhala ndi redundancy kwathunthu kuti ateteze ku zolephera. Kuperewera uku ndikofunikira pakuwonetsetsa kuyankha kotetezeka kwagalimoto pochepetsa zolakwika. Elon Musk akunena kuti mankhwala a kampani yake amapereka machitidwe awiri a single-chip (aliyense ali ndi ma neural unit awiri) omwe amagwira ntchito pawokha pofuna chitetezo.
Zomangamanga ziwiri, zodziyimira pawokha pa-chip, SoC iliyonse ili ndi ma accelerator awiri a NN omwe amatha kuwerengera nthawi imodzi kuti ateteze ku cholakwika chofewa.

Zomwe NVIDIA idakumana nazo pazithunzi zamasewera ndi kuwerengera kofananira kwatsimikizira kukhala kothandiza kwambiri kwa kampaniyo pakufulumizitsa mawerengedwe okhudzana ndi luntha lochita kupanga komanso kuwongolera magalimoto. Drive PX2 imapereka ma teraflops asanu ndi atatu, pafupifupi kasanu ndi kamodzi kuposa Xbox One. "Ndine wokonda kwambiri NVIDIA, amachita zinthu zabwino," adatero Musk panthawi yolengeza chip. "Koma tikamagwiritsa ntchito GPU, kwenikweni, tikulankhula za kutsanzira, ndipo magwiridwe antchito amachepa ndi bandwidth ya basi. Pamapeto pake, kusamutsa deta pakati pa GPU ndi CPU kumachepetsa dongosolo."
NVIDIA ikadali yotseguka kuti ipitilize mgwirizano ndi Tesla. Mtsogoleri wamkulu Jensen Huang adanena masiku angapo chilengezochi chitatha: "Ngati sizikuyenda, pazifukwa zilizonse Tesla sizikugwira ntchito, mukhoza kundiyimbira ndipo ndidzakhala wokondwa kwambiri kukuthandizani." Pambuyo pake mwezi womwewo, kampaniyo idatsimikizira Inverse kuti ikugwirabe ntchito ndi Tesla.
Tesla amagulitsa njira ya Partial Autopilot $3000 panthawi yogula galimoto kapena $4000 pambuyo pake. Kuyendetsa galimoto kwathunthu kumawononga $ 5000 yowonjezera yophatikizidwa ndi galimoto kapena $ 7000 pambuyo pake. A Musk akuti chip chatsopanocho chidzaphatikizidwa pamitengo iyi. Masiku ano, phukusi lamtengo wapatali limatanthawuza kuthandizira pazinthu monga Navigate pa Autopilot, ngakhale zimafunikirabe chidwi cha dalaivala.
Chaka chino, Tesla akulonjeza kuthandizira kuzindikira ndi kuyankha zizindikiro zoyimitsa ndi magetsi, komanso kuyendetsa galimoto m'misewu yamzindawu, monga gawo la phukusi la $ 5000. M'tsogolomu, padzakhalanso kusintha kwa misewu yodziwikiratu m'misewu ikuluikulu, magalimoto oyenderana ndi oyimitsidwa, komanso kuyitanira kwakutali kwagalimoto yoyimitsidwa kwa dalaivala. Pakafunika, Tesla idzalowa m'malo mwamagetsi a NVIDIA ndi yankho laulere kwa iwo omwe adagula phukusi lodula la Autopilot.
Zilibe kanthu ngati muli ndi kompyuta ya Tesla FSD kapena Tesla Nvidia yochokera pakompyuta. Zikadzafika chaka chino, Tesla akusinthani makompyuta.

Sizikudziwika kuti Tesla azitha kupereka liti Autopilot yokhazikika popanda kuyikapo dalaivala. Kampaniyo idakonza zomaliza ntchito yoyendetsa magalimoto oyenda m'mphepete mwa nyanja mpaka kugombe kumapeto kwa chaka cha 2017 (makamaka magalimoto amagalimoto), koma kuyesayesako kudachedwetsedwa m'malo mwakuti apeze yankho lachilengedwe chonse. Wantchito wakale wakale wa Google komanso woyambitsa mnzake wa Otto (womwe adapezedwa ndi Uber), Anthony Levandowski, adalengeza mu Disembala 2018 kuti adakwaniritsa cholinga chopanga galimoto yodziyendetsa yokha mdziko lonse Tesla asanachitike ndipo adasindikizanso kanema wofananira ngati umboni. :
Mu February chaka chino, Elon Musk adanena kuti autopilot yathunthu ikhala yotetezeka kumapeto kwa chaka chamawa. Ndizowoneka bwino posachedwa, popeza Volkswagen ikuyembekeza kuti magalimoto odziyimira pawokha azifika pofika 2021, ndipo ARM imapereka kulosera kwa 2024 ngati zenizeni. Ngati Bambo Musk akulondola, kuyamba kwa kupanga kwa Tesla's specialized neural processor ndi sitepe yofunikira kumbali iyi.
