This Year’s
Winning Autos

In this year’s Top 10 Tech Cars, as in the global auto industry at large, the Great Disconnect becomes more obvious. On the one hand, virtually every carmaker offers models that deploy technology in unabashed pursuit of energy efficiency and reduced environmental impact. In our group of honorees this year, the Tesla Model 3 and the charming Kia Niro hybrid fit in this category. Yet for all the talk of a Tesla-driven tipping point in electric transportation, EVs still make up a 0.5 percent drop in the global ocean of new cars. So in the real world—well, at least in the United States, where Washington is actually looking to weaken fuel economy standards and where a record two-thirds of buyers are choosing an SUV, pickup, or other light truck—today’s automotive innovation is arguably more about utility, horsepower, and performance.

2022—The Year the Hydrogen Economy Launched?

The Inflation Reduction Act and the war in Ukraine pump billions into clean hydrogen R&D

Among the technological visions that seem perpetually futuristic (think commercial nuclear fusion and maglev trains), the hydrogen economy has always been tantalizing. Hydrogen produced from renewable energy or nuclear power, with minimal greenhouse-gas emissions, could be piped or transported pretty much anywhere, using mostly existing infrastructure. It could power trucks, cars, planes, and ships and generate electricity, either in fuel cells or combustion turbines. In short, it could do anything fossil fuels do now, but with substantially reduced climate impact.

Now, after decades of false starts and overly optimistic projections, several factors are giving an unprecedented lift to clean hydrogen. In the United States, sweeping legislation capped a series of moves by the country’s Department of Energy (DOE) over the past year to drive down the cost of low-carbon hydrogen and stimulate demand for the fuel. And in Europe, a looming fossil-fuel crisis has sent officials scrambling to find alternatives to the 155 billion cubic meters of Russian natural gas that EU countries imported in 2021.

Q&A: Marc Raibert on the Boston Dynamics AI Institute

Boston Dynamics’s founder thinks creatively with $400 million AI Institute

Last week, Hyundai Motor Group and Boston Dynamics announced an initial investment of over US $400 million to launch the new Boston Dynamics AI Institute. The Institute was conceptualized (and will be led) by Marc Raibert, the founder of Boston Dynamics, with the goal of “solving the most important and difficult challenges facing the creation of advanced robots.” That sounds hugely promising, but of course we had questions—namely, what are those challenges, how is this new institute going to solve them, and what are these to-be-created advanced robots actually going to do? And fortunately, IEEE Spectrum was able to speak with Marc Raibert himself to get a better understanding of what the Institute will be all about.

GPIOs: Critical IP for Functional Safety Applications

The prevalence and complexity of electronics and software in automotive applications are increasing with every new generation of cars. The critical functions within the system on a chip (SoC) involve hardware and software that perform automotive-related signal communication at high data rates to and from the components off-chip. Every SoC includes general purpose IOs (GPIOs) on its periphery.

For automotive SoCs, GPIO IP is typically developed as Safety Element out of Context and delivered with a set of Assumptions of Use. It is important that the GPIO blocks are treated as a safety related logic. In this role, GPIOs need safety analysis to mitigate any faults occurring in them before the result of fault occurrence causes a system-wide failure.
