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 such as the CAN bus, GPIO pins, and I2C and SPI devices.

Project e-smart: an e-mobility research platform for students made by students – Part 1

This report presents a student project at the Institute for Internal Combustion Engines and Automotive Engineering (IVK) at the University of Stuttgart in which a commercial compact car vehicle with combustion engine was converted to an electric vehicle.

Understanding wire-less charging

The increasing popularity of battery-powered consumer electronic devices such as portable media players, smartphones and tablets has led to a host of different chargers and a tangle of wires littering the home. The concept of wirelessly charging the devices, i.e. without any direct-wired connection, has been around for a while but is now rapidly gaining interest to make it more flexible and useable. But what are the different techniques available, and what are the design challenges an engineer needs to deal with?

Large Li-ion battery packs: Active balancing improves many parameters – part 2

In Part 1 one of this article it was shown that an active cell balancing Battery Management System (BMS) is the best solution for large Li-Ion battery packs for automotive applications. A conclusion was reached that active cell balancing is a key enabler of the EV revolution. The 2nd part of this article reviews the popular active balancing methods and presents a unique active cell balancing BMS solution from National Semiconductor.

 

Use of common mode chokes in high speed data links

Complementing widely used infotainment bus systems such as MOST or IEEE 1394, serial data links are increasingly used for point-to-point high-speed data connections in the infotainment realm. National Semiconductor’s SerDes technology is explained here in detail.

Audi, Daimler infotainment systems take center stage at CES

Cars are increasingly changing their character – from a motorized vehicle with a few electronic components to a giant mobile universal device with a set of wheels. At the Consumer Electronics Show in Las Vegas, vehicle manufacturers Audi and Daimler have confirmed this mutation process by highlighting their latest developments.
