In this article an overview will be given of how LEDs are now replacing conventional lighting throughout automotive system designs, not merely in a piecemeal manner. It will also describe how innovative analog/digital devices are starting to present engineers with more effective means by which to drive and control the LED strings and modules deployed in these systems.

The number of ECUs you’ll find in even the most standard of car models is staggering. The complexity of new functions such as adaptive cruise control, blind spot detection and hill start assist further complicate the software development and testing process. There is also an increasing appreciation and adoption of safety standards for the functional aspects of software used for some of these functions. Testing and debugging more complex ECU environments will bring certification challenges.

Ironically, more choices are not always good as this can lead to a wavering state. Similarly, selecting between a controller and converter is tough, especially when there are so many choices with which to design your application. However, just like any decision, the selection can be made easier if given a framework upon which to base this choice. Before going into depth with a step-by-step framework, first we need to understand what a converter or a controller means in the world of power electronics.

For testing ESS Battery Management Systems (BMS), the use of “virtual” batteries is proving to be an effective alternative to the use of real batteries. They allow the engineer to avoid the risks of damage to the batteries – and subsequent costs – while testing and optimizing the BMS design in a close-to-reality loading environment. Maplesoft, a developer of battery modeling technology, recently partnered with ControlWorks, Inc. of South Korea to develop a turn-key BMS system. The end result was a battery model capable of being configured to represent a stack of up to 144 cells that can be connected in any combination of parallel and series networks.

The concept of autonomous vehicles or unmanned drones has generated considerable public interest in recent times. While the idea appears technically plausible, in order to make this a reality, development teams face a tough task. This article will discuss the standards developers need to be aware of and the steps they need to take to ensure safety of autonomous and other automotive applications.

To meet growing bandwidth and communication requirements for cars, more designers are tapping into automotive Ethernet interfaces. For automotive Ethernet, it’s critical to verify both the intellectual property (IP) block-level components and its sub-features and the system-level integration and interoperability implications. This article takes a look at how verification IP can facilitate development of the rich features and functions that consumers now expect in their cars.

LTC-P323-Fig1

Arguably, one of the most demanding applications for driving HB LEDs is found in automotive headlamp applications, as they must deliver high power (typically between 50W to 75W) and fit into thermal- and space-constrained enclosures. Power conversion solutions must be highly efficient, robust in features and reliability while being very compact and cost effective. Linear Technology is continually redefining its family of LED drivers to meet these challenges with HB LED driver ICs such as the LT3791.

One of the most interesting and fastest growing automobile safety applications is Advanced Driver Assistance Systems (ADAS). These systems use a combination of sensors, cameras and displays to provide greater driver visibility and also react to dangerous situations when a driver doesn’t. The ability to deliver reliable, easy to integrate and cost effective video solutions will be key enablers of the next generation of ADAS features, which are increasing driver safety and ultimately consumer demand for new vehicles. Sophisticated SoCs introduced reliability issues, booting up too slowly to provide timely rear camera video to the driver immediately after initial ignition of the vehicle.

The Art of Automotive Application Design: Performance Optimizations for a 32bit Automotive Microcontroller

February 16, 2015  by  


Giovanni-DAquino

In the world of automotive microcontrollers, whatever the design aspect, the goal is to get the maximum performance respecting application requirements at a minimum price. The improvement process is driven by cost aspects, but equally from what customers expect in term of features and performances requested of the SoC.

We’ll illustrate the major considerations designers will face when meeting application requirements with a 32bit microcontroller architecture design, and explain how to get maximum performance during software development by knowing the architecture and using common debugging techniques.

Ethernet Will Connect the Connected Vehicle

February 9, 2015  by  


BMW-data-buses

Current projections indicate that by 2020, more than 120 million cars will be equipped with Ethernet connectivity, with the premium segment connecting up to 35 systems with Ethernet, and in mid-range vehicles, between 8-20 systems. Ethernet is well-qualified to serve as the bus of choice for next-gen vehicles because it delivers the necessary capacity, performance and versatility unavailable from CAN bus, FlexRay, MOST, J1850/1939 and other semi-proprietary protocols. This article will show how Ethernet can meet the requirements of tomorrow’s vehicles and how it will shape the evolution of automotive networks over the next 5-10 years.
