Automotive Industry

Today, anyone who has driven a modern automobile cannot help but be impressed by the complexity and scope of the vehicle's electronic systems, all working together to make the occupants’ experience safer and more pleasurable. Cars today protect you, entertain you, anticipate your every move, and some are self-driving!

So, how does RTI go about addressing testing needs while aiming at the complexity of next-generation Electronic Control Units (ECUs) before it is installed in your favorite sedan, wagon or SUV? 

At RTI, we make it easy for you to come to a “one-stop shop”. Our specialty in custom and integrated test fixtures gives us the advantage to modify the fixture to your test applications, test strategies, and methods. See below for more info.

Your Product Development Stages are critical to TEST:

In product development, all new designs are verified and tested prior to production release. What is becoming more important in test strategy is Hardware in the Loop (HIL). RTI can help you plan this strategy from the ground up.

Process Testing and Integration considerations:

In terms of verifying the quality of the assembly process, the automotive industry is somewhat conservative. The primary reason is the environment faced in the automotive industry: temperature ranges from 40° to +250°C, multiple G-force shock potential demands a design that is more robust, and where component densities per square centimeter will likely remain lower than other consumer products. Also, as most area ANALOG rates will be under 150 MGHZ for the foreseeable future, test pads will stay mechanically and electrically “test-a-able”, and viable. Add the issues of product liability when a safety system fails promotes a "go slow/careful" philosophy. So, in-circuit testing (ICT)  is still viable in the assembly line for several more years to come.

Certain Mechanical- Electrical testing is comprised of the following subtasks: 

  • Component testing 
  • Functional testing 
  • Durability investigations (HI-REL)


Suitable component testing allows cost-effective verification of simulation results as well as a validation of the involved engine subsystems. Component investigations contribute to the shortening of development times as they can be performed at a time before the completed stages are available. FEV distinguishes between static component testing, pulse testing, and dynamic rig-testing.


Despite the high standard of component testing achieved today, functional testing conditions are still indispensable. Especially for measured variables and locations immediately affected by the actual process, the higher expenditure must be accepted. And, at times, functional tests performed are characterized by the use of sophisticated measuring technologies.

If it’s feasible, the following measures are taken to ensure a time and cost-efficient test procedure: 
  • Test bench installation and driving cycle operation without utilizing special measuring technology 
  • Extensive in-parallel data acquisitions
  • Utilization of an actual hardware specimen for the analysis of various subsystems is required (“SAMPLING”) of your golden device
