CONTROL UNIT TESTS - Look behind the scenes of complex electronics

Electronic control units have become indispensable components in vehicles. The number as well as complexity of functions continues to grow. It is thus even more important to perform systematic and comprehensive tests in each phase of the development process. We support you in the best possible way with suitable test tools and test procedures.

Here we provide suitable hardware and software solutions for the different phases of product development. You will get quick tests results with hand-held systems following short training. You can quickly determine the most important measuring data with hand-held testers in the field or create suitable stimuli. In order to cover the possible faults and diagnostic tests, our systems are supplemented with fault simulators.

Our test systems that can be automated flexibly, combined with powerful software solutions, enable performance of sound and repeatable function tests for your product. Whether you work in advance development, series development, production or quality assurance - your product quality is important to us.

6-channel functional tester for endurance tests

The functional testers for durability testing of parking brake control devices typically consists of 6 slots (subracks). Each is an independent functional unit and has an internal ARM9-based process control computer, via an individual test sequences can be defined and carried out using the Lua scripting language.

An essential key component is the SMART own high-precision wheel speed simulation for mapping complex types of sensors. To operate ECU-specific I / O channels individually developed MCM-plug-in module is used. To reduce costs, a high-quality high-current constant is used and the power Power distributed over a server to the six samples. Due to its modular and autonomous structure of each Subracks these stand-alone can be used.
