Connectivity promotes theft prevention in connected vehicles
Thieves may soon learn it doesn’t pay to mess with a smart car. Mike Norris • Silicon Labs More than three million cars are sold in the U.S. annually, and over 700,000 are stolen. Unfortunately for car owners, anti-theft technologies have not kept pace with modern developments, creating a gaping hole in the automotive theft […]
Vehicles move into the software realm
New processors have been developed with vehicle safety and connectivity in mind. David Maples, Texas Instruments The trend towards autonomous driving, electrification and connectivity to the cloud is making software a priority. That’s why automotive designers are reworking the architecture of modern-day vehicles and migrating toward a software-defined car. Many systems within cars today are […]
Sensor-realistic simulation in real time
Advanced sensor simulation techniques can be used to validate functions for autonomous driving throughout the development process. Caius Seiger, Dr. Gregor Sievers • dSPACE GmbH Sensor-realistic simulation is a powerful way of validating sensor systems, which are an integral part of autonomous vehicles. Increasingly powerful computer systems make it possible to generate realistic sensor data […]
Memory and functional safety in autonomous vehicles
As software and its associated memory footprint continue to expand in vehicles, automotive system designers need a deeper understanding of DRAM and its impact. Robert Bielby • Micron Technology Today’s high-end vehicles are recognized as among the largest embedded software applications in the world, with a total memory footprint expected to grow from today’s staggering […]

Is Li-Fi “To Be” or “Not To Be”? Part 1: Context
Optical wireless communications in the form of “Li-Fi” is a technical alternative to RF-based Wi-Fi with distinct strengths and weaknesses. You are undoubtedly familiar with Wi-Fi – a contraction of “Wireless Fidelity”– which has become the de facto standard for wireless connectivity between the Internet or local area networks and PCs, smartphones, countless appliances, gadgets, […]
Assessing safety and performance in connected vehicles
Testing and certification for vehicle and infrastructure devices ensure software and systems will perform as advertised. Ralph Buckingham, Wayne Stewart, Intertek As consumers look to connect their cars, the technology behind these vehicles and their various connected components is evolving far more quickly than standards governing them can change. Consequently, manufacturers and developers sometimes lack […]
Delivering advanced face recognition capabilities at the edge
By Rick Bye, Senior Product Marketing Manager, NXP Using face recognition for access control The COVID-19 pandemic highlights concerns over how many different surfaces we often touch during a typical day. For example, everyone entering a secured building, such as a workplace or after-hours hotel entrance, touches access control keypads that present an ideal surface […]
