Auto Network Speeds Rise As Carmakers Prep For Autonomy


In-vehicle networks are starting to migrate from domain architectures to zonal architectures, an approach that will simplify and speed up communication in a vehicle using fewer protocols, less wiring, and ultimately lower cost. Zonal architectures will partition vehicles into zones that are more manageable and flexible, but getting there will take time. There is so much legacy technology in ... » read more

Securing Automotive Ethernet With MACsec Silicon IP


In today’s cars, the Ethernet standard is the go-to solution for connecting zonal gateways to the central compute units that handle ADAS functionality. However, in-vehicle networks are vulnerable to a number of security threats, including eavesdropping, denial-of-service attacks, man-in-the middle attacks, and unauthorized access. This white paper explores how MACsec provides an effective sol... » read more

Week In Review: Auto, Security, Pervasive Computing


Former Apple engineer Weibao Wang was indicted for stealing Apple’s autonomous vehicle hardware and software IP and giving the information to Chinese competitors. Among other items, authorities said they found source code for the project on the engineer’s personal laptop, which was seized at his home. Wang fled to China the same day a search warrant was executed. This is one of five cases b... » read more

Ethernet-Based In-Car Networking and Trends in Automotive Communications


A technical paper titled "A Perspective on Ethernet in Automotive Communications—Current Status and Future Trends" was published by researchers at University of Catania. Abstract "Automated driving requires correct perception of the surrounding environment in any driving condition. To achieve this result, not only are many more sensors than in current Advanced Driver Assistant Systems (AD... » read more

Automotive Bandwidth Issues Grow As Data Skyrockets


Bandwidth requirements for future vehicles are set to explode as the amount of data moving within vehicles, between vehicles, and between vehicles and infrastructure, continues to grow rapidly. That data will be necessary for a variety of functions, some of which are here today and many of which are still in development. On the safety side, that includes everything from early warning systems... » read more

Navigating The Intersection Of Safety And Security


Vehicle systems and the semiconductors used within them are some of the most complex electronics seen today. In the past, electronics going into vehicle systems implemented flat architectures with isolated functions controlling various components of the power train and vehicle dynamics. However, to support the realization of Level 4 and Level 5 (L4/L5) autonomous driving, a massive restructure ... » read more

Managing Today’s Advanced Vehicle Networks Design Challenges


Today’s automotive electrical and electronic (E/E) architectures are highly complex, with the functionality of many vehicle features distributed across multiple discrete ECUs. The ECUs, sensors and actuators are not all directly connected, and much of the data communication occurs across networks, often through gateways over several networks. Modern E/E architectures are formally organized ar... » read more

Zonal Architectures Play Key Role In Vehicle Security


The automotive ecosystem is starting to shift toward zonal architectures, making vehicle functionality less dependent on the underlying hardware and allowing more flexibility in what gets processed where. The impact of that shift is both broad and significant. For carmakers, it could lead to hardware consolidation and more options for failovers in case something goes wrong with any system in... » read more

Competing Auto Sensor Fusion Approaches


As today’s internal-combustion engines are replaced by electric/electronic vehicles, mechanical-system sensors will be supplanted by numerous electronic sensors both for efficient operation and for achieving various levels of autonomy. Some of these new sensors will operate alone, but many prominent ones will need their outputs combined — or “fused” — with the outputs of other sensor... » read more
