What Are You Smoking? Automating Short Circuit Testing for Automotive Systems and Harness Design

June 18, 2015  by  

By Mike Stamper, Mentor Automotive


Protecting vehicle wire harnesses from overloads that could be catastrophic is a critical design criterion. The designer must ensure that the fusing strategy protects the wiring. This process typically involves calculating the maximum load on each wire manually and then comparing the result to a spreadsheet that may have been created many years ago. This process is very error prone due to its manual nature. You might find that alarming — and it is — but cars and planes are driving and flying just fine. There are several reasons that is so…

The Quality of Your Code is now the Quality of Your Brand

June 5, 2015  by  

By John J. Paliotta, Chief Technology Officer, Vector Software


Modern vehicles have evolved into complex integrated technology platforms with embedded software powering all major systems including: engine control, power train, braking and airbags, driver assistance, and infotainment. As automobiles evolve from mechanical to software-enabled devices, automakers must rethink fundamental product development principles, including moving from a sequential design process to a more agile approach, with higher degrees of collaboration between self-directed, cross-functional teams.

Introduction to ADAS and the Secure Connected Car

June 3, 2015  by  

Prem Arora, Director of Marketing, Microsemi (www.microsemi.com)

ADAS technology can be based on intelligent, interconnected networks. This is the case with Vehicle-to-Vehicle (V2V), or Vehicle-to-Infrastructure (V2I), systems, which together are known as V2X systems. Security is imperative. In order for the promise of V2X to be realized, the system must ensure two things. First, it is critical that all V2X messages originate from a trustworthy source. Second, there must be safeguards to ensure that no message is modified between sender and receiver.

Top Three Design Considerations for Battery Management in Electric Vehicles

May 21, 2015  by  

By Gary MacDonald, Intersil Corporation

Designing battery management systems (BMS) for electric vehicles (EVs) is one of the more complex design challenges facing engineers, and the most important design consideration is BMS IC selection. This article examines the top three BMS design considerations, including a close look at battery pack architectures, inter-module communications or daisy chaining BMS modules, and the optimum PCB layout configuration.

MOST offers numerous dedicated communication channels for the transmission of multimedia content in various formats and data rates. In addition to these dedicated channels, there is the Asynchronous Channel, over which MOST Ethernet offers a service referring to Ethernet, the well-known standard in computer networking. This service allows for a TCP/IP or UDP/IP architecture on top, which brings a vast range of applications into the automotive domain. The usage of these applications not only requires a suitable protocol architecture, but further requirements concerning bandwidth or communication latency have to be fulfilled.

Renault Uses Maple to Develop New Motor for Full Electric Vehicle

April 28, 2015  by  


In order to successfully enter the growing electric vehicle market, Renault wanted to create a new motor design. In the earlier phases, they turned to Maple and started quickly with first-order approximations of the rotor. One particular issue of growing complexity that was solved with Maple was that of the slot wedge, which holds the rotor wire in place to ensure reliability over both maximum loads and long-term operation

ECU Consolidation; Learning from Other Industries

April 22, 2015  by  

By Georg Doll, General Manager of Automotive Solutions at Wind River, an Intel company


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.
