The GOcontroll Moduline IV automates testing and validation of modern automotive lighting systems, combining electrical, optical, and thermal measurements.

Today’s automotive lighting systems are complex electronic subsystems, communicating over CAN and LIN networks. Verifying their performance requires more than switching lights on and off — it demands smart, data-driven control. The GOcontroll Moduline IV provides the foundation for a complete Vehicle Lighting Test Platform, capable of commanding headlamps, DRLs, indicators, and adaptive beams while measuring brightness, current, voltage, and temperature. The result is an efficient, modular solution for developing, validating, and calibrating next-generation lighting technologies.

Modern headlights are intelligent. They adjust beam patterns dynamically, dim automatically, and respond to vehicle signals in real time. The Moduline IV enables complete automation of these test procedures.

It manages:

• CAN/LIN-based light control for adaptive headlamps and tail lamps.

• Voltage and current monitoring of each lighting channel.

• Light intensity measurement via calibrated photodiodes or lux sensors.

• Thermal feedback from lamp housings and ambient sensors.

Unlike vision-based camera systems, this setup uses precisely positioned photodiodes at key beam locations — hotspot, cutoff, and glare zones — to evaluate performance accurately and repeatably. The system captures and evaluates data in real time, allowing engineers to validate brightness levels, cutoff sharpness, and adaptive transitions without complex image processing.

The GOcontroll Moduline IV features a rugged, modular design with up to eight plug-in I/O modules, perfectly suited for automotive lighting validation.

A typical setup includes:

• 6-channel input modules for photodiodes, temperature sensors, and current shunts.

• 6-channel output modules for digital and PWM control of lighting actuators and motor drivers.

• CAN and LIN interfaces for communication with the lighting ECU.

• Digital inputs for test triggers or environmental sensors.

This modularity allows one controller to manage all aspects of the lighting test bench — from electrical power delivery to optical intensity monitoring — within a compact, configurable platform.

Using MATLAB Simulink or Node-RED, engineers can design and execute automated lighting test routines directly on the controller.

Examples include:

• High-to-low beam transitions, logging response times and intensity changes.

• Dynamic indicator validation, checking sweep timing and voltage stability.

• Adaptive-beam testing, correlating CAN commands with lux sensor readings.

• Thermal derating tests, observing brightness behavior as temperature rises.

Each test can be fully automated — the Moduline IV issues CAN commands, reads sensor feedback, evaluates performance, and logs results autonomously.

Every test run is recorded in high detail. The Moduline IV logs timestamped data for all channels, including light output, current draw, and temperature changes. Engineers can:

• Export logs in CSV format for external analysis.

• Visualize live data through Ethernet-based dashboards.

• Automatically flag results that deviate from set tolerances.

This unified data approach simplifies correlation between electrical input and optical performance, allowing teams to identify degradation, misalignment, or ECU communication issues quickly.

From prototype validation to end-of-line verification, the Moduline IV adapts to every stage of lighting system development. Multiple controllers can be networked over Ethernet or CAN, coordinating multi-lamp test rigs or parallel production lines.

Its modular I/O, real-time control, and integrated communication make it equally suited for:

• R&D testing of new lighting technologies.

• ECU calibration and adaptive-beam tuning.

• Automated functional testing in production environments.

The GOcontroll Moduline IV provides a reliable, compact, and flexible platform that unifies electrical, optical, and thermal validation — making it the ideal controller for intelligent automotive lighting test systems.
