Analog AM Band Interference in Electric Vehicles

Carolyn Mozheev — Fri, 03 Nov 2023 21:26:38 +0000

There is an effort in the US Congress to require automakers to maintain AM radio in all vehicles, including new electric vehicles (EVs). However, the nature of EVs and their operating conditions, including acceleration and deceleration, pose a challenge to ensuring electromagnetic compatibility (EMC) with the analog AM band radio. This study, conducted by the Center for Automotive Research (CAR), shows that mitigating electromagnetic interference (EMI) in an EV is challenging and could lead to added costs for vehicle manufacturers. The cost of mitigation depends upon the electrical architecture of the vehicle and entails several design and engineering tradeoffs. Automakers may mitigate some EMI through vehicle engineering choices, including shielding, filtering, active noise cancellation, and strategic placement of components. These mitigation techniques can improve analog AM band reception. However, a total vehicle system EMC requirement would need to be included from the beginning of any future EV redesign, if not already considered by the automakers, to eliminate the need for piecemeal late-stage mitigations. These costs can be avoided by deleting analog AM radio from vehicles and providing consumers with alternative products for in-vehicle audio content.

International Scan of Connected and Automated Vehicle Technology Deployment Efforts

swhitehouse@cargroup.org — Tue, 13 Dec 2016 19:48:24 +0000

Connected and automated vehicle (CAV) technology development is now a global phenomenon. In just the last few years, research and pilot projects have proliferated rapidly across the world. Still, while research and development projects have become practically countless, operational deployment of CAV technology remains rare. Only a fraction of recently developed technology is available to real-world drivers. Automated driving systems (defined as SAE levels 3-5) have thus far been publically deployed only in strictly controlled environments and experimental test pilots. Connected vehicle systems are increasingly used for fleet management and infotainment, but the life-saving potential of connected vehicles through cooperative intelligent transportation systems (C-ITS) has scarcely been tapped.

Considering the complexity of transportation systems, vehicle manufacturers cannot deploy many transformational technologies on their own. Bringing advanced connected and automated vehicle technology to our public roads requires coordination with public agencies at various levels of government. This report documents the most significant projects of 2016 in which public-private partnerships worked together to advance the state of connected and automated vehicle technologies through real-world testing and deployment.
