Agilent Technologies The functional testing of automotive electronic control modules (ECMs) presents many challenges, mainly due to the physical loads connected to ECMs: solenoids, motors, spark plugs, electromechanical transducers and so on...
Avoiding EMC Problems in Automotive Systems
By Randy Frank, contributing editor While electromagnetic compatibility is frequently regarded as a importantly issue for any electronic system, its potential to disrupt critical automotive systems has lead to numerous industry specifications and standards to avoid problems. This article explores EMC/EMI issues, provides a few solutions to common problems, a systems approach to dealing with EMC and identifies several specifications...
New Semis Help Designers Turn on the Power
By Randy Frank, contributing editor When automakers add more electronic features to differentiate their vehicles, they have to consider the impact on the vehicle’s power supply. Some new systems, such as stop-start systems and regenerative braking are being added to improve fuel economy and reduce emissions. To simplify the power management task in all systems, suppliers continue to introduce more efficient products and use techniques that reduce power consumption. More area efficient, dual-sided cooling packages for power MOSFETs, the use switching technology in Class D audio amplifiers and LED headlights are examples of industry efforts to use less power...

Design Challenges for Digital Instrument Clusters
By Andy Gryc, QNX Software Systems Digital instrument clusters are poised to supersede analog clusters in next-generation vehicles. This may seem surprising at first, since digital clusters require higher-end CPUs and much more software than their analog counterparts, not to mention large LCD panels. Why, then, are automakers adopting them? ...
