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

New Challenges For Connected Vehicles


Connected vehicles are all about convenience and safety. Modern vehicles are connected to the Internet via wireless networks, consumer apps, and infotainment systems, and there is work underway to connect them over 5G to guided driving. But there also are challenges to making all of this work securely, safely, and as expected throughout the expected lifetimes of chips and systems. The goal i... » read more

Data Security Challenges In Automotive


Automakers are scrambling to prevent security breaches and data hacks in new vehicles while simultaneously adding new and increasingly autonomous features into vehicles that can open the door to new vulnerabilities. These two goals are often at odds. As with security in any complex system, nothing is ever completely secure. But even getting a handle on this multilayered issue is a challenge.... » read more

Securing Short-Range Communications


Short-range wireless communication technology is in widespread use and growing rapidly, adding conveniences for consumers while also opening the door to a whole range of cyberattacks. This technology is common across a variety of applications, from wireless key fobs to unlock a car and start the ignition, to tags used to help drivers find misplaced items such as car keys. RFID also is starti... » 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

Big Changes Ahead For Connected Vehicles


Carmakers are reworking their electronic architectures so they can tap into a growing number of external services and internal options, similar to the way a data center taps into various services over its internal network. In the past, this has been largely confined to internal services such as on-board Internet connectivity, and external traffic routing and music. The current vision is to g... » read more

Security Concerns Rise For Connected Autos


The auto industry is transforming itself toward a future in which the automobile increasingly will be connected using V2X and 5G. Driver assistance will improve, and ultimately cars will be guided by AI and machine learning. But all of this will be closely watched by hackers, looking for an opening and a potentially large and untraceable payout. The replacement of mechanical functionality wi... » read more

Privacy Protection A Must For Driver Monitoring


Driver monitoring systems are so tied into a vehicle's architecture that soon the driver will not be able to opt out because the vehicle will only operate if the driver is detected and monitored. This is raising privacy concerns about whether enough security is in place for the data to remain private. At the very least, laws and regulations in every geography where the vehicle will operate a... » read more

A Survey of Autonomous Vehicles: Enabling Communication Technologies and Challenges


Abstract "The Department of Transport in the United Kingdom recorded 25,080 motor vehicle fatalities in 2019. This situation stresses the need for an intelligent transport system (ITS) that improves road safety and security by avoiding human errors with the use of autonomous vehicles (AVs). Therefore, this survey discusses the current development of two main components of an ITS: (1) gathering... » read more
