I was had planned to do a long post on self-driving cars a quite long time. I was planning to do one this spring, but I might not do that, because it seems that predictions that self-driving cars would be here in 2020 were far too rosy. Five years ago, several companies including Nissan and Toyota promised self-driving cars in 2020. So it may be wise to take any new forecasts with a grain of salt. Hare is a worth to check out article of the current status of self-driving cars:
Surprise! 2020 Is Not the Year for Self-Driving Cars
https://spectrum.ieee.org/transportation/self-driving/surprise-2020-is-not-the-year-for-selfdriving-cars
In March, because of the coronavirus, self-driving car companies, including Argo, Aurora, Cruise, Pony, and Waymo, suspended vehicle testing and operations that involved a human driver. Around the same time, Waymo and Ford released open data sets of information collected during autonomous-vehicle tests and challenged developers to use them to come up with faster and smarter self-driving algorithms.
It seems that the self-driving car industry still hopes to make meaningful progress on autonomous vehicles (AVs) this year, but the industry is slowed by the pandemic and facing a set of very hard problems that have gotten no easier to solve over the years.

Volvo kokosi käyttöjärjestelmät yhteen – Android, Linux, Qnx ja Autosar
https://www.uusiteknologia.fi/2021/07/05/volvo-kokosi-kayttojarjestelmat-yhteen-android-linux-qnx-ja-autosar/
Volvo siirtää ohjelmistokehityksen yhtiön sisälle parantaakseen autojensa ohjelmistokäyttöisiä toimintoja ja ominaisuuksia. Käyttöön tulee oma käyttöjärjestelmä, jonka alla toimivat kaupalliset käyttöjärjestelmät kuten Android Automotive OS, QNX, Autosar ja Linux.
Volvo lupaa seuraavan sukupolven sähkö-Volvoihin käyttöjärjestelmää, jota se kutsuu nimellä VolvoCars.OS. Se rakentuu yhtiön käyttämistä eri käyttöjärjestelmiä sekä pilvipalveluista. Yhteisen ohjelmistoympäristön alla toimivia käyttöjärjestelmiä ovat Android Automotive OS, QNX, AUTOSAR ja Linux.
Useiden sovellusrajapintojen (API), kuten aikaisemmin ilmoitetun Extended Vehicle APIn, kautta VolvoCars.OS antaa kehittäjille pääsyn auton sisäisiin ominaisuuksiin, kuten anturitietoihin ja käyttöliittymiin, sekä pilvipohjaisiin ominaisuuksiin asiakkaan suostumuksen mukaan. Tämä antaa kehittäjille mahdollisuuden luoda uusia palveluja ja sovelluksia Volvon autoihin.

Bosch CVT Transmission For EVs Improves Performance And Efficiency
https://insideevs.com/news/520403/bosh-cvt4ev-cvt-electric-vehicles/
So many manufacturers are telling us changing gears in an EV is not needed, yet here comes Bosch to contradict them.
Virtually all modern EVs send their power to the road via a direct drive and reduction gear system – they are single-speed machines. No shifting of gears or variable ratios in sight and manufacturers rely on electric motors’ well known torque to provide a blend of acceleration, efficiency and higher speed cruising ability.
The only current vehicle that has a geared transmission is the Porsche Taycan (and its sister model, the Audi E-Tron GT), which gets a two-speed gearbox for the rear motor, but it is an exception. There was also the unsuccessful Coda Sedan that tried to adapt a CVT (continuously variable transmission) to make the most of its electric motor, but sadly there are none around to see how that might have worked.
It has been touting its EV-specific CVT as providing two key benefits: improving an electric vehicle’s range and performance. The company says the transmission itself is a lightly modified version of a traditional pushbelt CVT, which it calls CVT4EV. Bosch says that with this transmission installed, the vehicle gets improved acceleration, top speed, and because torque demand on the traction motor is reduced, it is also more efficient.
The company also mentions the estimated efficiency gain through using CVT4EV and it is around 4 percent, although it doesn’t provide a similar figure for performance gains. The transmission is currently being tested in a Volkswagen e-Golf by Bosch Transmission Technology, a Dutch subsidiary of the company, but so far no commercial application for it has been announced.

What Tesla’s bet on iron-based batteries means for manufacturers
https://techcrunch.com/2021/07/28/what-teslas-bet-on-iron-based-batteries-means-for-manufacturers/
Elon Musk earlier this week made his most bullish statements yet on iron-based batteries, noting that Tesla is making a “long-term shift” toward older, cheaper lithium-iron-phosphate (LFP) cells in its energy storage products and some entry-level EVs.
The Tesla CEO mused that the company’s batteries may eventually be roughly two-thirds iron-based and one-third nickel-based across its products. “And this is actually good because there’s plenty of iron in the world,” he added.
Musk’s comments reflect a change that is already underway within the automotive sector, mainly in China. Battery chemistries outside of China have been predominantly nickel-based — specifically nickel-manganese-cobalt (NMC) and nickel-cobalt-aluminum (NCA). These newer chemistries have become attractive to automakers due to their higher energy density, letting original equipment manufacturers (OEMs) improve the range of their batteries.

Study: EVs cost more to service than ICE vehicles
We Predict studied about 19 million vehicles between the 2016 and 2021 model years.
https://europe.autonews.com/automakers/study-evs-cost-more-service-ice-vehicles
It costs more to service electric vehicles than their gasoline-powered counterparts, but the gap narrows over time, according to new data from analytics firm We Predict.
The company, which released data this year saying EVs were 2.3 times more expensive to service than ICE vehicles after three months of ownership, said Wednesday that there is a caveat: After one year, EVs are just 1.6 times more expensive to service.
We Predict looked at the data of about 19 million vehicles between the 2016 and 2021 model years.
The main factors in the narrowing over that nine-month period included a 77 percent drop in maintenance costs as well as a slight decline in repair costs. Still, the data showed that service techs are spending twice as long diagnosing problems with EVs vs. those with gasoline vehicles. They are spending 1.5 times longer fixing them, and their average labor rate was 1.3 times higher.

The National Highway Traffic Safety Administration has opened an official investigation into Tesla’s “self-driving” Autopilot system. Cars from the company, owned by billionaire Elon Musk, have been involved in several accidents but the investigation is going to focus on 11 specific cases. Those were accidents where cars crashed into first responders’ scenes.
“Since January 2018, the Office of Defects Investigation (ODI) has identified eleven crashes in which Tesla models of various configurations have encountered first responder scenes and subsequently struck one or more vehicles involved with those scenes. The incidents are listed at the end of this summary by date, city, and state,”

Autonomisten ajoneuvojen täytyy jatkuvasti tietää, mitä niiden ympärillä tapahtuu. Useimmille tämä tarkoittaa useiden anturitekniikoiden yhdistämistä, vaikka esimerkiksi Tesla onkin hylännyt valotutkan. Ehkäpä ratkaisu on ollut hätiköity, kuten Toshiban uusin lidar osoittaa.
Toshiban uusin valotutka on markkinoiden pienin ja kestää parhaiten tärinää. Silti se näkee 200 metrin päähän suuremmalla tarkkuudella kuin mikään nykyisistä kaupallisista ratkaisuista. Lidar on tarkoitettu robottiautoihin, mutta ensi alkuun se auttaa erilaisia kuljetusvälineitä kuten kuorma-autoja havaitsemaan esimerkiksi tien vajoamiset ja maanvyörymät.

https://etn.fi/index.php/13-news/12454-katoaako-can-vayla-autoista
CAN-väylä tuli markkinoille vuonna 1991. Se korvasi laitteiden väliset erilliset IO-linjat 2-johtoisella viestiväylällä. Fyysinen kerros ja protokolla oli erotettu, joten väylä kesti hyvin kohinaa. Väylä on reaaliaikainen ja edullinen hyödyntää, joten sen suosio on helppo ymmärtää.
CAN-väylällä on kuitenkin rajoituksensa. Alkuperäisen datanopeus oli rajoitettu yhteen megabittiin sekunnissa ja pian kymmenen vuoden ikäinen FD-laajennus (flexible datarate) nosti nopeuden 5 megabittiin. On selvä, ettei esimerkiksi resoluutiotaan jatkuvasti kasvattavien kameroiden ja ECU-yksiköiden välistä dataliikennettä voi perustaa CAN-väylän varaan.
Tällä hetkellä autoelektroniikassa onkin menossa selvä vallankumous. CAN-väylä on korvautumassa ohjelmistopohjaisilla arkkitehtuureilla ja ethernet-yhteyksillä. Fyysisenä linkkinä ethernet tukee jopa 10 gigabitin datayhteyksiä.
Sähköajoneuvot ovat osaltaan vaikuttamassa CAN-väylän katoamiseen. Moni uusi autonvalmistaja on täysin uusi toimija, eikä niillä ole vanhaa perintöä vaikuttamassa. Siksi väyläratkaisut mietitään usein CAN-väylä unohtaen.
Tämä näkyy autoteollisuuden ethernet-ohjainten markkinoilla. Vuonna 2019 markkina oli kooltaan 1,6 miljardia dollaria, mutta vuonna 2024 puhutaan jo lähes viidestä miljardista dollarista.

The tough calculus of emissions and the future of EVs
From materials and batteries to manufacturing, calculating the real carbon cost of EVs is just getting started
https://techcrunch.com/2021/08/22/the-tough-calculus-of-emissions-and-the-future-of-evs/?tpcc=ECFB2021
Investors and politicians embracing a vision of an all-electric car future believe that path will significantly reduce global carbon dioxide emissions. That’s far from clear.
A growing body of research points to the likelihood that widespread replacement of conventional cars with EVs would likely have a relatively small impact on global emissions. And it’s even possible that the outcome would increase emissions.
The issue is not primarily about the emissions resulting from producing electricity. Instead, it’s what we know and don’t know about what happens before an EV is delivered to a customer, namely, the “embodied” emissions arising from the labyrinthine supply chains to obtain and process all the materials needed to fabricate batteries.

This is an important point. Many others in the autonomous space have mirrored this sentiment. Don Burnette, co-founder and CEO of Kodiak Robotics, says his company is exclusively focused on trucking for the moment because it’s a much easier problem to solve.

When you make technology components that millions of human lives will depend on, meeting both schedules and final operating safety are, to say the least, essential. This is the responsibility shouldered by Ankur Ganguli, executive director of Vehicle Motion Embedded Controls at General Motors Co.
“My team works on the embedded controls that go into the propulsion and chassis systems (e.g., engines, transmissions, electric batteries and motors, brakes, steering and suspensions) for our full portfolio of cars and trucks—millions of vehicles every year,” says Ganguli.
Ganguli has about 2,000 people on her team and “we work and coordinate with thousands of people across dozens of organizations and other teams to integrate the controls that we develop. We have to deliver safety criticality like that of aerospace systems at the product-development pace of smartphones and video games.”

Onko robottiauto ylipäätään mahdollinen?
https://etn.fi/index.php/13-news/12479-onko-robottiauto-ylipaataan-mahdollinen
Autonominen ajaminen on tavoite, jonka parissa työskentelevät niin autonvalmistajat, puolijohdetalot kuin tutkimuslaitoksetkin. Mercedez Benzin koordinoimassa AI-SEE-tutkimushankkeessa yritetään kehittää ratkaisuja, jotka mahdollistavat automisen ajamisen kaikissa sää- ja valaistusolosuhteissa.
Suomesta hankkeessa ovat mukana VTT, autonomisen ajamisen teknologiaa kehittävä ohjelmistoyritys Unikie, signaalikäsittelyyn erikoistunut Meluta sekä Patria, joka haastaa ajoneuvoteollisuuden ratkaisuja off road -näkökulmasta. Tutkimustiimin johtaja Matti Kutila VTT:ltä sanoo raflaavasti, että hankkeessa kehitettävät anturit ja niiden datan käsittely on täysin uutta. – Ne siirtävät nykyiset saatavilla olevat autotutkat ja -kamerat museoiden hyllyille.
Aika vahvasti sanottu, Kutila myöntää itsekin. – Mutta on siinä totta toinen puoli, jos tutkimushanke onnistuu edes 70-prosenttisesti saavuttamaan tavoitteet. Valitettavasti nykyinen anturitekniikka ei mahdollista automaattista ajamista kaikkialla ja kaikissa olosuhteissa. Siihen syyt löytyvät nimittäin fysiikan laeista.
- Nykyiset optiset anturit pohjautuvat pääosin piipohjaisiin ja niiden spektrivaste loppuu 950 nanometrissä. Toisaalta ihmisen silmä ”näkee tai ainakin silmänpohja reagoi” näihin aallonpituuksiin, jolloin tehoja ei voi nostaa, koska sokeutumisen vaara on ilmeinen. Toisaalta tutkat toimivat 24 tai 77 GHz radiotaajuuksilla ja niiden resoluutio ei nykytekniikalla saavuta optisia antureita, Kutila selventää nykytekniikan ongelmia.

The Top 10 EV Battery Makers CATL, LG Chem, and Panasonic control 69 percent of the market
https://spectrum.ieee.org/the-top-10-ev-battery-makers
It’s a great time to be a battery maker: The world could see 145 million electric vehicles on roads by 2030, versus 10 million in 2020, according to the International Energy Agency. Buyers registered 3 million new EVs globally last year. Those cars were stuffed with 134.5 gigawatt-hours of batteries — a 40 percent jump in one year, according to Adamas Intelligence. Proliferation aside, many EVs require ever-larger batteries to meet consumer demands for driving range, zippy performance, and now SUV size and utility. Ryan Castilloux, managing director of Adamas Intelligence, says COVID-19 barely dented mushrooming growth: “Through five months of 2021, the total auto battery capacity deployed on the world’s roads is greater than all of 2018.”
Just six companies—BYD, CATL, LG Energy Solution, Panasonic, Samsung SDI, and SK Innovation—were responsible for supplying 87 percent of batteries and battery metals in passenger EVs in the second half of 2020. Tesla’s deployment of 22.5 gigawatt-hours of batteries in that period was nearly as much as its five closest competitors combined: China’s BYD, Hyundai, Mercedes, Renault, and Volkswagen.

Leaded Petrol Finally Eradicated From The World As Last Country Ends Use

The age of leaded gasoline is officially over, marking a well overdue end to a major threat to the health of humans and the planet.
The United Nations Environment Programme (UNEP) announced Monday that no country in the world now uses leaded petrol for cars and lorries after Algeria became the last country to make the switch in July 2021.
There’s strong evidence it can reduce IQ scores in people exposed as children and it’s been associated with lower impulse control, which in turn can lead to increases in crime and violence.
The person behind the development of leaded gas was an American chemical engineer named Thomas Midgley Jr. As if his legacy wasn’t stained enough, this guy also introduced the world to chlorofluorocarbon (CFCs) refrigerants, the chemicals responsible for corroding a hole in Earth’s ozone layer.

Suomalaisen ohjelmistoyhtiö Unikien tekniikka ohjaa pian Uudenkaupungin tehtaalta valmistuvat autot automaattiohjauksella varastointialueelle odottamaan kuljetusta. Aoneuvot ajetaan alueelle ilman kuljettajaa. Mukana linkit esittelyvideoihin.
Tampelaisen Unikien automatisoitu pysäköintiratkaisu ei edellytä yrityksen mukaan ajoneuvoilta autonomisen ajamisen ominaisuuksia. Autoja ohjataan tehdasalueelle luodun älykkään infrastruktuuri avulla, jossa anturit ja pilvipohjainen tiedonkäsittely mahdollistavat ajoneuvon ja alueen välisen viestinnän.
Autonomisen pysäköinnin tavoitteena on tehostaa Uudenkaupungin tehtaan logistiikkaa ja siten tuoda merkittäviä kustannussäästöjä. Testiajot ovat osoittaneet, että järjestelmä toimii luotettavasti erilaisissa sääolosuhteissa.
”Valmet Automotiven Uudenkaupungin tehtaalla olemme käyttäneet samaa automaattisen pysäköinnin teknologiaa, ota tulemme esittelemään BMW:n, Fordin, Jaguar-Land Roverin, Volkswagen konsernin ja Mercedes Benzin autoissa’’, sanoo Vesa Kiviranta Unikien autoteollisuudesta vastaava liiketoimintajohtaja.
