Accelerating Sensor Development with Rapid Prototyping and Model-Based Design

September 4, 2015  by  

By Martin Hein, Hella Fahrzeugkomponenten GmbH

Before automotive OEMs purchase a new sensor system, they want to see a real-time prototype of the sensor working in a vehicle environment so as to evaluate its performance and potentially modify its specifications. To meet this requirement, we use a custom rapid control prototyping platform and Model-Based Design to build real-time prototypes of new designs early in the development process. The real-time prototype (known at Hella as an A-sample) serves both as a proof of concept and as a living specification throughout development…

Freescale Semiconductor, Inc.

Tire pressure monitoring systems (TPMS) are electronic systems that monitor air pressure inside pneumatic tires. TPMS senses and then transmits tire-pressure information via wireless communication. TPMS provides several benefits. It increases safety by reporting under-inflated tires that could compromise vehicle handling or cause the tire to fail unexpectedly. Consequently, TPMS is now part of the mandatory equipment for passenger cars in most developed countries. In this article we will describe challenges designing, testing, and verifying TPMS systems designed to measure the higher pressure found in truck tires…

Semiconductor Technology Helps Break Down the Barriers to Widespread Electric Vehicle Adoption

July 24, 2015  by  

By Sravan Vanaparthy, Technical Marketing Manager, ON Semiconductor

The anticipated penetration of the combustion engine powered passenger car market by vehicles with electrified powertrains – be they pure electric or hybrid – is not happening as quickly as perhaps many industry observers had anticipated just a few years ago. There are several reasons for this, not least that many automakers such as Ford and Volkswagen have been able to develop smaller capacity engines with direct gasoline injection and newer turbo technologies that develop the required power but with high efficiency, better economy and lower emissions. In addition, battery technology has still not made the giant step needed to enable the development of mass production electric vehicles that have a range between charges that sits comfortably with the car buying mass market segment and puts convenience on a par with combustion powered units…

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 (

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.
