Our core functional integration services

Car access systems

We implement and validate advanced access technologies, ensuring both user convenience and system security.

Digital key

Implementation aligned with Car Connectivity Consortium (CCC) standards for smartphone-based access and vehicle start.

Key fob parametrization & validation

Configuration, testing, and validation of physical key fobs to ensure secure pairing, functional reliability (e.g., passive entry, personalized settings), and compliance with OEM standards.

Secure key management

Real-time issuance and revocation of digital credentials.

Car sharing

Multi-user vehicle access with secure, dynamic provisioning.

Scalability

Architected for individual use, fleets, rental platforms, and shared mobility solutions.

Test house

Development near test service for interoperability and regression testing after start of production (SOP).

Body electronics testing

We test systems that shape comfort and brand perception. Testing is done both manually and via automated end-of-line (EOL) setups.

Lighting (interior and exterior)

Validation of interior and exterior lighting across ECU and system level, including LIN/CAN-controlled ambient, headlamp, and rear lamp functions. Testing covers diagnostics, flashing, robustness, and failure scenarios under real-load and automated conditions to ensure stable integration and release readiness.

HVAC and climate control

System-level validation of HVAC ECUs including actuator control, sensor feedback, and network communication. Scope covers functional behavior, diagnostics, gateway integration, automated regression runs, flashing scenarios, and stress testing under varying load conditions.

Window, sunroof & seat functionalities

End-to-end testing of comfort functions such as window lifters, sunroof modules, and seat control units including safety mechanisms like anti-pinch protection. Includes EOL scenarios, flash robustness tests, failure injection, and automated long-run validation across software releases.

Infotainment and communication

We ensure drivers get the connected experiences they expect.

Seamless integration of Android Auto, Apple CarPlay, and other platforms (In car apps)
Support for voice assistants, media streaming, and OTA updates
Robust testing across OS versions and device variants

Child presence detection

Child Presence Detection (CPD) is a safety function designed to protect vulnerable occupants, particularly children aged 0–6, from heat-related risks inside locked vehicles. To achieve Euro NCAP 5-star compliance from 2025 onwards, CPD must rely on direct sensing technologies such as in-cabin radar to detect micro-movements like breathing. The system integrates stationary interior sensors, ECU processing, and alert mechanisms to notify the vehicle owner via smartphone or warning signals. Robust validation requires extensive functional testing, real-vehicle campaigns, data collection, and machine-learning validation to minimize false positives and false negatives under real-world environmental conditions.

End-to-end integration testing from sensor to driver notification

E/E flash validation and over-the-air updates

Repeated flash validation ensures the robustness of modern ECUs in software-defined vehicles. We validate ECU resilience under frequent software updates by simulating real-world stress conditions. This process prevents system degradation, guarantees stability, and supports OTA-readiness—essential for dynamic vehicle architectures and future-proof software strategies.
