By John Blyler – Advanced driver assistance systems (ADAS) rely heavily on modern radar technology. And why not? Radar uses electromagnetic waves to sense the environment. It can operate over a long distance in poor visibility or inclement weather conditions. Designing automotive RF that accurately captures diverse traffic situations will be essential in making autonomous operations safe.
Radar systems are no newcomer to the automotive space. In the past, automotive radar was used in vehicles for basic operations such as automatic emergency braking (AEB) and adaptive cruise control (ACC), where the radar sensor only had to provide the vehicle with information relating to the distance and speed of the target in front of it.
However, recent trends to deploy a fully autonomous vehicle have increased the amount of information that a vehicle demands from the radar sensor. Specifically, after detecting a target, the host vehicle must determine several things, such as the distance to a target – be it another car, a person, a stationary object, or the like. The radar must also calculate how fast the target is approaching or departing; whether it is to the right, left, or straight ahead of the vehicle; on the road or above the ground; and the nature of the target, i.e., pedestrian or vehicle, for example.
Automotive radar technology can provide essential, real-time information to the vehicle’s onboard embedded computers and software algorithms to answer these questions by providing five-dimensional datasets: Range, Doppler, Azimuthal direction of arrival (DoA), Elevation direction of arrival (DoA), and Micro-Doppler.
As vehicles migrate from SAE level 1 to level 5 full autonomy, automotive radar technology will be used for far more than emergency braking and adaptive cruise control with ever-increasing reliability and accuracy demands. more>
By Jake Whitehead, Dia Adhikari Smith and Thara Philip – The Morrison government on Friday released a plan to reduce carbon emissions from Australia’s road transport sector. Controversially, it ruled out consumer incentives to encourage electric vehicle uptake. The disappointing document is not the electric vehicle jump-start the country sorely needs.
By Joseph Henrich – When President Coolidge signed the Johnson-Reed Act into law in 1924, he drained the well-spring of American ingenuity. The new policy sought to restore the ethnic homogeneity of 1890 America by tightening the 1921 immigration quotas. As a result, immigration from eastern Europe and Italy plummeted, and Asian immigrants were banned. Assessing the law’s impact, the economists 
By Thomas Hofstätter, Melanie Krawina, Bernhard Mühlreiter, Stefan Pöhler, and Andreas Tschiesner – Electric mobility, driverless cars, automated factories, and ridesharing—these are just a few of the major disruptions the auto industry faced even before the COVID-19 crisis. Now with travel deeply curtailed by the pandemic, and in the midst of worldwide factory closures, slumping car sales, and massive layoffs, it’s natural to wonder what the “next normal” for the auto sector will look like. Over the past few months, we’ve seen the first indicators of this automotive future becoming visible, with the biggest industry changes yet to come.
By Patrick Hertzke, Jitesh Khanna, Bhavesh Mittal, and Felix Richter – Inventors patented the first electric bikes back in the 1890s, but their innovations never garnered the same attention as other early-transportation milestones, including the first subways and the Model T Ford. Today, however, several trends have converged to bring e-bikes out of obscurity. Sales of electric vehicles (EVs) are increasing as governments crack down on emissions. Meanwhile, innovators have introduced new technologies and business models that are breathing life into the market for small-format EVs (those with two or three wheels). Improbable as it may seem, e-bikes could finally be having their day.
