Mastering body electronics — from software to fleet

When customers experience a vehicle, their first impressions are often shaped by body functions: the way the lights respond, how the climate system adapts, or how seamlessly comfort features operate. For OEMs, this means that body electronics are not just technical subsystems — they are a direct reflection of brand identity, comfort, and safety.

At Technica Engineering, we help you validate these functions end-to-end, ensuring reliability, consistency, and quality across all generations of your vehicle programs. Most important, we are specialized in testing central ECUs, like body domain controllers or HPCs, that are the central point of the in-vehicle-network for the body functionalities.

We offer solutions to real industry challenges

Complexity at scale
Modern body systems involve dozens of ECUs, gateways, and evolving software stacks. We orchestrate this complexity through a unified testing approach, from early software validation to real-world fleet testing.
Time-to-market pressure
By shifting testing activities left, we help you identify issues at the earliest possible stage, preventing costly errors later in the integration chain. We ensure that complete vehicle HILs and your test fleet can focus on testing customer functions, instead of individual ECU errors or integration issues that could be found at an earlier stage.
Customer experience assurance
From intelligent lighting control to HVAC performance, we ensure that comfort and safety functions work flawlessly — in the lab and on the road.

Our core body functions services

Component testing incl. SIL

Turning component validation into a seamless, automated process — from code to confidence.

Automated pull request testing
Smoke & nightly test suites
ECU recovery (using a permanently connected debugger to automatically reflash the DUT after a faulty flash process. This ensures that a nightly / weekly automated test run can continue)
Continuous integration and reporting

Subsystem & integration testing

Where components meet collaboration — validating complete body domains under real-world conditions.

Testing the body HPC / domain controller on integration level with all connected ECUs
Smoke and Go/NoGo test suites to identify faulty software releases before flashing it to bigger test farms / fleets
Manual, semi-automated, and CI-based testing modes
Stress & robustness validation under real load conditions
Automated flashing, debugging, and pre-analysis of logs
