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.

Riittääkö litium sähköautojen akkuihin?
https://etn.fi/index.php/13-news/11027-riittaako-litium-sahkoautojen-akkuihin
Koronapandemia on hidastanut sähköautojen myyntiä kaikkialla, mutta kyse on väliaikaisesta hidastumisesta. Ajoneuvot ovat muuttumassa sähköiseksi, mikä vauhdittaa akuissa käytettävänä litiumin kysyntää. Mutta kuinka kauaksi aikaa litium riittää?
Roskill-tutkimuslaitoksen ennusteen mukaan litiumin kysyntä kasvaa vuoteen 2030 asti 19,7 prosentin vuosivauhtia. Autojen akustojen kohdalla kasvu on 28 prosenttia ja vuosikymmenen lopulla sähköautojen osuus litiumin kulutuksesta on jo 75 prosenttia.
Tällä hetkellä litiumreservien kooksi arvioidaan lähes 100 miljoonaa tonnia. Suuri osa niistä löytyy kymmenestä suurimmasta esiintymästä. Analyytikoiden arvion mukaan tunnetut ja realistisesti käytössä olevat litiumreservit riittävät sähköautoilun tarpeisiin jopa tämän vuosisadan loppuun mennessä.
Kuinka paljon yhden sähköauton akusto sitten sisältää litiumia? Akustojen kapasiteetti tietenkin vaihtelee, mutta esimerkiksi Teslan 70 kilowattitunnin akussa on 63 kiloa litiumkarbonaattia. Siitä litiumin osuus on 12 kiloa eli noin viidennes.
Yhdestä litiumtonnista riittää näin materiaalia noin 80 sähköauton akustoon.

AV Answers in Ten Words or Less
https://www.eetimes.com/av-answers-in-ten-words-or-less/
If ten-word answers can kill you in political campaigns, then two words is all it takes to shut down the autonomous vehicle (AV) safety debate: Saving lives. Who could possibly argue with that? Now just add in the issues of diversity, inclusivity and access to mobility for disadvantaged citizens and it is all over. Game, set and match to AVs, right?
No so fast. There’s one tiny problem no one talks about: Robotaxis don’t work.
If the goal of new mobility services is to achieve diversity, inclusivity and accessibility using technologies which don’t work, then limiting the debate to robotaxis shows a real paucity of ambition. I propose teleportation, which saves lives, saves time and saves the environment. How did the political lobbyists miss that one?
Two-word answers
Let’s forget about all the political positioning and all the technical jargon and just go back to basics. What is the purpose of transportation? It is a simple question that can be reduced to a two-word answer: Moving stuff. What stuff? People and goods.
Throughout history, from the horse, through maritime, rail, the motor car, aviation to micro-mobility the role of transportation has been to move people and goods. Today, all AV technology development can be segmented into those two groups. EE Times has written extensively about AVs and discusses four categories: Last-mile goods AVs, fixed-route AVs, autonomous trucks, and robotaxis.
You don’t need to understand anything about technology to understand that smaller, lighter and slower AVs present the lowest risk, which is why we are set to see deployment of last-mile goods AVs enter operation first. Common sense tells us that if a small, slow-speed goods AV crashes and spoils a cargo of, say, hot pizza, that is just a cost of business.
In comparison if a people-AV crashes and kills its human cargo and maybe some pedestrians too, that is a legal nightmare in which we can be certain every party involved will look to pin the blame on someone else. For the foreseeable future, that “someone else” looks set to be the primary role of the hapless safety driver.
Behind the soundbites and euphoria of the AV proponents and all the political posturing is a cold, hard reality that goods AVs will enter safe operation and commercial viability years — and possibly decades — ahead of people AVs. Saving pizzas doesn’t generate quite the same buzz on Capitol Hill as saving lives, but my role here is just to state the obvious, so I’ll leave the messaging to Waymo’s communications team to work on.
How are we going to save lives?
If the solution to the conundrum of human drivers killing more than 38,000 people on U.S. roadways each year isn’t AVs, then what is it? It’s another two-word answer: Effective legislation. To understand more about what can be done to save lives safely, quickly and broadly, let’s refer to the safety technologies covered by the updated EU General Safety Regulation (GSR), summarized in the slide below, which features in Continental’s 2019 Fact Book.
From 2022 the EU GSR requires privately-owned passenger vehicles to be fitted with advanced emergency braking (AEB), emergency lane keeping, intelligent speed assistance, event (accident) data recorder, alcohol interlock facilitation, drowsiness/attention detection and driver readiness monitor. From 2024 the legislation further requires the installation of advanced distraction recognition systems.
As EE Times reported this week, a lack of ADAS benchmarks is haunting the U.S. car industry, while Bloomberg reported on “The Life-Saving Car Technology No One Wants.” Both articles address the same issue: Life-saving technology which is covered by effective legislation in the EU, but isn’t required in the U.S.
Most of these critical life-saving technologies are included in the Moving Forward Act currently passing through Congress and I am unaware of even a single AV tech company which has publicly backed the provisions for saving lives in the Act. Perhaps these companies are interested in saving lives only if it uses their technology?
How are we going to save lives? By making human drivers safer with driver monitoring and assistance technology. That means ADAS-focused tier one suppliers like Aptiv, Bosch, Continental, Magna, Veoneer and ZF; camera and radar sensor suppliers like Analog Devices, Infineon and On Semiconductor; processor suppliers like Mobileye (Intel), NXP, Renesas, Texas Instruments, Toshiba and Xilinx; and DMS software suppliers like Eyesight, Seeing Machines and Smart Eye.
Here’s a ten-word answer President Bartlet might approve of: “Safer roadways using effective technology that is affordable and works.”

How Do You Insure a Car Without a Driver?
https://www.eetimes.com/how-do-you-insure-a-car-without-a-driver/
How safe is a car without a driver? That’s a decade-old question the world keeps asking automotive OEMs, but the people who come up with the answer first might very well be auto insurance agents.
The lack of an answer thus far has created a gulf between the technology/automotive companies pushing to make autonomous vehicles (AVs) a commercial reality and consumers skeptical of the safety of autonomous vehicles (without a human driver).
The crying needs to produce safe AVs are better software, better hardware, and better systems integration, together producing a trail of evidence demonstrating safe operation. Instrumental to achieving these advances are safety standards such as ISO 26262, SOTIF, and ANSI/UL 4600. In particular, the UL 4600 standard published earlier this year is designed to bring standardization to assessing the safety case. UL 4600’s goal is to help AV developers who must present — before going commercial with self-driving cars — structured arguments to stakeholders explaining why they think their vehicle is safe.
Stakeholders include federal regulators, municipal authorities, insurance companies, industry peers and consumers. Among these, insurers might just hold the key to building consumer confidence in AV safety. Consumers might not like insurance companies, but they tend to trust their coldblooded risk assessments.
The case in point is a survey done by J.D. Power in fall, 2018. Asked who they trust most to perform reliable safety testing to fully automated vehicles, 500 auto insurance customers named the Insurance Institute for Highway Safety or its subsidiary, the Highway Loss Data Institute, as groups they would trust most (34%). Auto manufacturers (12%), the federal government (9%), and state governments (4%) lagged far behind.

Lucid’s new all-electric sedan will let owners send energy to their homes by mid-2021
https://tcrn.ch/3gdq2e4
Lucid Motors said Wednesday that its upcoming all-electric Air sedan will have fast-charging capability that will let owners add 300 miles of range to the battery in 20 minutes and a home-charging unit that will allow owners to send energy from their car to their home.
Lucid said it is able to hit this benchmark because the vehicle has a 900-volt electrical architecture when combined with its lithium-ion cells, battery and thermal management system and powertrain efficiency. Most electric vehicles — with the exception of the Porsche Taycan and future Kia EVs — have a 400-volt architecture.

Almost one in three – or 32 percent – of all cars produced worldwide in 2019 came out of China. As shown in numbers by the automobile manufacturers’ association OICA, the world manufactures less cars than it did in 2014, but several Asian markets actually were able to grow their production volumes.
India exhibited one of the biggest increases – almost 15 percent in five years to 3.6 million cars annually. The biggest decrease in production hit the ailing U.S. car industry, which lost 40 percent of its domestic production between 2014 and 2019.
Germany also make less cars at home, but German manufacturers like Volkswagen are a part of the rising Chinese production.

Momentum Dynamics’ wireless charging pads can keep EVs topped up while they park, and they are already being tested in electric bus trials.
Wireless Charging Tech to Keep EVs on the Go
https://spectrum.ieee.org/cars-that-think/transportation/advanced-cars/wireless-charging-tech-to-keep-evs-on-the-go
Norway, already a world leader in EV adoption, will soon mark a world’s first: An Oslo-based fleet of Jaguar I-Pace taxis that can charge wirelessly even as they queue up for passengers.
That inductive charging technology, developed by a former NASA engineer at Pennsylvania-based Momentum Dynamics, aims to solve perhaps the biggest disconnect in EVs: How to bring convenient charging to the urban masses—including apartment dwellers and drivers of taxis, buses, and delivery trucks—without clogging every inch of prime real estate with bulky, unsightly chargers. The conundrum becomes more pressing with the introduction of new electric models, and each additional government mandate for fewer fossil-fueled cars and lower carbon emissions.
A great example of that action to combat climate-change is Oslo, whose ambitious ElectriCity plan will require that all taxis produce zero tailpipe emissions by 2024—effectively banning even gasoline-electric hybrid models. The result of punitive taxes on fossil-fueled cars and enticing incentives for electric models: 50 percent of Norway’s new cars are now EVs, a higher percentage by far than any nation.
Norway’s government has decreed that all new cars must be zero-emissions by 2025.
That carrot-and-stick urgency led to a partnership between Jaguar, Momentum Dynamics, Nordic taxi operator Cabonline, and charging company Fortam Recharge. The group aims to create the world’s first wireless-charging taxi fleet. To that end, Jaguar is equipping 25 I-Pace SUVs with Momentum Dynamic’s inductive charging pads.
The pads, which are about 60 cm square, are rated at 50 to 75 kilowatts.
Using resonant magnetic coupling operating at 85 hertz, a charging pad will route enough energy to a taxi’s batteries add about 80 kilometers of range for every 15 minutes hovering over the inductive coils
electric bus trials in four U.S. cities. The transit trials featured a Chinese-built BYD bus in Wenatchee, Wash. that slurped energy from a charging pad installed along its route at a rate of 200 kilowatts. That’s on par with some of the fastest DC chargers, enough to “keep the bus in 24/7 operation, without ever going back to the garage” to recharge
The company claims its technology delivers 94-percent charging efficiency, which holds steady as scalable power climbs to 200 or even 350 kilowatts. That’s a winning contrast with DC fast chargers, whose efficiency drops sharply at higher power because of massive resistance and the resulting heat that demands liquid-cooled cables, which themselves create more energy losses.
Recharge Infra tabbed Momentum Dynamics after learning it could deliver 50 kilowatts or more through a roughly 18-centimeter air gap between vehicle and pavement—a huge improvement over companies that promised no more than 11 kilowatts.
Backers cite several spin-off benefits. With systems buried entirely underground, the plan eliminates: chargers to compete for prime parking space or sidewalks; moving parts and worries about vandalism or damage from elements; and wired infrastructure, including unsightly towers and arms for electric buses, to pollute the view.

In June, the U.S. National Highway Traffic Safety Administration (NHTSA) detailed the Automated Vehicle Transparency and Engagement for Safe Testing (AV TEST), a program that purports to provide a robust source of information about autonomous vehicle testing. Today marked the official launch of AV TEST after several months of ramp-up, beginning with a tool for tracking driverless pilots in 17 cities across nine states. But despite lofty promises from the NHTSA of the transparency AV TEST will herald, its current incarnation — at least from first impressions — is bare-bones at best.
Companies including Beep, Cruise, Fiat Chrysler, Nuro, Toyota, Uber, Local Motors, Navya, and Waymo have agreed to participate in AV TEST so far, along with those that have previously submitted testing information to NHTSA, including Aurora, Easymile, Kodiak Robotics, Lyft, TuSimple, Nvidia, and Zoox. The tracking tool reveals on-road testing locations and activity data like vehicle types, uses, dates, frequency, vehicle counts, and routes. And it shows information about state vehicle operation regulations, emergency response plans, and legislation, as well as links to the voluntary safety reports some vehicle operators publish.

Volkswagen-backed QuantumScape to go public via SPAC to bring solid-state batteries to EVs
https://techcrunch.com/2020/09/03/vw-backed-quantumscape/?tpcc=ECFB2020
Electric vehicles on the road today are equipped with lithium-ion batteries. A battery contains two electrodes. There’s an anode (negative) on one side and a cathode (positive) on the other. An electrolyte sits in the middle and acts as the courier that moves ions between the electrodes when charging and discharging. Solid-state batteries use a solid electrolyte and not a liquid or gel-based electrolyte found in lithium-ion batteries.
Developers claim that solid electrolytes have greater energy density, which translates into squeezing more range out of a smaller and lighter battery. Solid electrolytes also are supposed to be better at thermal management, reducing the risk of fire and the reliance on the kinds of cooling systems found in today’s EVs.

Software-Defined Vehicles
The electrification of cars makes all sorts of things possible.
https://semiengineering.com/software-defined-vehicles/
Automobiles long ago stopped being purely mechanical systems. But as more components are electrified — and, in particular, as the drivetrain is electrified — cars are becoming software-defined vehicles.
Some think of such cars as computers on wheels. But as these systems continue to evolve, adding in more assisted and semi-autonomous capabilities, that comparison is looking increasingly simplistic.
“It’s actually not one computer on wheels. It’s a data center on wheels,” said Frank Schirrmeister, senior group director for solution marketing at Cadence. “Within that data center, I have domain-specific compute — not just pure processing, but areas that are NPU-accelerated, areas that are graphics-accelerated, and what have you.”
With most major components being controlled by software, automakers can simplify their product lines while they explore new revenue options. Customers, meanwhile, will have more options and more flexibility in how they buy and equip a car.
Many mostly-mechanical vehicles are still on the road today. In their purest form, the only electrical elements are those things that have to be electrical — typically, the lights and radio. But even with the radio, older controls are mechanical.
Select electrical options have been available for quite a while — electric door-locks and windows, for example. But the guts of the car have remained stubbornly mechanical until the current period, where electric is becoming the future of automobiles, driven by both environmental needs and economics.

Complex Automotive Software: What’s Your Strategy?
https://www.eetimes.com/complex-automotive-software-whats-your-strategy/
Software expertise and experience are becoming crucial core competency that is in short supply in the auto industry. The growing amount of software functionality that are embedded in every new car model will require increased competency by OEMs, Tier 1 and software suppliers. Software platforms are a required strategy to be able to keep up with the software explosion that are coming from customer’s demand for connected cars and apps-centric infotainment systems and the many ADAS functions.

Autoilun ja liikkumisen sähköistyminen kehittyy nopeasti, vaikka jotkut epäilevät koko kehityksen ”vihreyttä”. Nyt Eindhovenin teknisessä korkeakoulussa tehty tutkimus osoittaa, että sähköauto on selvästi aiemmin arvioitua ympäristöystävällisempi, vaikka mukaan otetaan akun valmistuksen ja sähköntuotannon päästöt.
Tuoreessa tutkimuksessa kritisoidaan aiempia tutkimuksia, joissa on epäilty sähköautojen ekologisuutta. Uuden tutkimuksen mukaan virhekäsityksiä on kuusi ja ne kumotaan yksi kerrallaan.
