The number of electronic control units (ECUs) being incorporated into vehicles has risen at an almost exponential rate over the last few years – as the complexity of the safety, infotainment and comfort systems across the board (from economy models right through to luxury ones) has continued to increase at a rapid pace. This has serious and far-reaching implications for car manufacturers, since the cabling that is needed to connect all this hardware together takes up more space (which is now at a premium) and also adds to the overall weight of the vehicle (which impacts directly on its expected fuel efficiency). By networking or multiplexing it will be possible to overcome the restrictiveness of conventional, increasingly outdated wiring arrangements and create a more effective system for the distributing of crucial data.

Today’s vehicles must be responsive to the driver’s slightest of intentions, while providing the highest levels of safety and reliability under the most extreme conditions. Manufacturers have turned to increasingly sophisticated software and electronics, adding yet another layer of complexity as well as the opportunity for expensive and image-bruising defects and recalls. Product line engineering (PLE) is a recognized discipline within systems engineering that is being applied to the automotive world to address precisely these kinds of complexities.

Engine knock occurs in engine cylinders because of improper ignition timing or faulty components. Modern cars incorporate knock-sensor systems for engines to minimize knocking, which can maximize engine lifetime, increase power, and improve fuel efficiency. This article discusses engine knock basics and how to set up a knock-sensor signal-conditioning system.

Initially, advanced driver assistance systems (ADAS) applications, such as adaptive cruise control and lane departure warning were convenience features. Previously high performance CPUs were considered the best devices for these, but the need for compute performance balanced with lower power consumption is driving engineers to consider FPGA devices.

Over the past few years, Flanders’ DRIVE has developed into a research center for the Belgian vehicle industry, which supports the sector with a hands-on approach and a permanent and flexible focus on the actual needs of the sector. In the years ahead, Flanders’ DRIVE wants to play a leading part in the transformation of the vehicle industry towards a green and smart mobility industry.
The ECU performs mission-critical tasks, so the DC/DC converter is essential to the safe operation of a vehicle. The converter also must be efficient. A DC/DC converter is only as good as its controller, however. New technology successfully reduces component count using the digital processing capabilities of an MCU.
While designing an embedded item the interference of all components becomes a very important factor that can have an influence in all assembly operations. Using FloEFD, it is quite simple to explore various constructions under different conditions in details. The reliable results of calculations are based on a consideration of geometrical optics as well as heat transfer specific data.

As the number and types of connected devices continues to grow, so does the amount of software contained in these devices. The forecast of 20 billion connected devices in 2020 brings also the challenge of managing the software over the air (OTA) witout the need to perform it on-site. Firmware over-the-air (FOTA) is the most efficient way to ensure that connected devices and cars properly operate.

The simple CAN ECU is a thing of the past. Now, a typical ECU utilizes many functions of the AUTOSAR basic software to per- form its complex tasks. However, the more functions there are, the more difficult and extensive the configuration process is too. Without tool support, developers would be lost.
