What drove automotive electronics in 2012: The most popular stories

December 20, 2012 // By Christoph Hammerschmidt
In 2012, Advanced Driver Assistance Systems, Automated Driving and connected vehicles dominated the headlines in the automotive electronics industry. Nevertheless, the engineers - you, our readers - preferred more in-depth information to seemingly unimposing topics: Batteries, electric drivetrains and powering the in-vehicle electronics. Interestingly, the articles with the highest click rates have been published already in 2011 and 2010 - a hint that the information contained herein is useful even after years.

German carmakers agree on 48V on-board supply, charging plug

Car makers Audi, BMW, Daimler, Porsche and Volkswagen have agreed to jointly incorporate a number of common architectural elements for their on-board power network. These include an additional 48V section and a charging connector type for all electric and hybrid vehicles as well as CAN bus interfaces supporting partial network operation.

Steer-by-wire – a solution to many design challenges

Despite recent setbacks, the steer-by-wire technology is alive and well – at least in specific off-highway markets. In this realm, many X-by-wire solutions are already in production and could easily be adopted by the passenger car industry. The article provides an overview over technologies, standards and players.

Modern ECU brings Diesel efficiency to aircraft engine

Piston engines for airplanes exclusively burn gasoline - to be more exact, heavily leaded AVGAS. While fuel-efficient Diesel engines see growing acceptance in cars, above the clouds rather old gas guzzler designs still dominate the market. Now engine design company RED aircraft GmbH has introduced a Diesel engine for small airplanes.

 

In-vehicle infotainment software architecture: Genivi and beyond - Part 1

 

With cars increasingly becoming networked IT entities, the security threats are also growing. The most visible gateway for hacking attempts to cars is the infotainment domain. Thus, next generation infotainment system architectures must address these issues from the ground up. The article discusses architectural approaches which guarantee the necessary level of security.

Bridging the chasm between HTML5 and the hardware with PPS messaging

 

Human-Machine Interfaces (HMIs) developed with HTML5 reside in a high-level, virtualized environment, and they work well in this environment. This fact does not preclude their needing to access hardware, however. In mobile devices, for example, they need to retrieve the device orientation and, if there are GPS or accelerometer chips, information these chips provide for applications that use geo-location. In-vehicle systems need to retrieve even more information from low-level components
