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

Will Automotive Ethernet Win?


As internal combustion engines are replaced by electric motors, and mechanical linkages increasingly replaced by electronic messaging, an in-vehicle network is needed to facilitate communication. Ethernet, amended for automotive and other time-sensitive applications, appears to be the network of choice. But is that choice a done deal? And will Ethernet replace all other in-car networks? The ... » read more

Securing ADAS At The Chip Level


The advent of ADAS, Advanced Driver Assistance Systems, is making a dramatic impact on new vehicles. It provides many helpful functions such as automotive night vision, forward collision warnings, collision avoidance, and lane departure warnings. In order to operate, ADAS requires the computerization of most of the functions of the vehicle. This results in from 50 to over 100 electronic control... » read more

Battle Brewing Over Automotive Display Protocols


Displays are multiplying in new and future automobiles. That means a lot more display data moving around the vehicle and traveling some distance between sensor and processor. While existing protocols can handle some of the new duties, new protocols also are being developed specifically for this application. “Automotive displays are proliferating, increasing in numbers and in pixel densi... » read more

Vehicle Communications Network Is Due For Overhaul


The Controller Area Network (CAN), one of the main communications networks in an automobile, is headed for a security overhaul — if not a wholesale replacement. Initially devised in the 1980s to allow electronic components in a vehicle to communicate directly without a central computer in between, the CAN bus has become a growing security risk as more functions are automated and integrated... » read more
