HMI Validation Systems


HMI Validation System is a professional CAN-based validation solution designed to test and verify the functional behavior of Human Machine Interfaces (HMIs). This system uses controlled CAN bus signal simulation and monitoring to validate whether the HMI responds correctly to different operating conditions. The solution works as a test environment where predefined or custom CAN scenarios are applied to the HMI under test. Based on these CAN inputs, the system verifies display indications, warning messages, and touch responses for correctness, timing, and logic. This approach ensures that the HMI behavior matches the intended CAN specifications.

The HMI Validation System eliminates the dependency on vehicle-based testing by providing a repeatable and controlled CAN testing setup. It enables engineers to detect functional issues, logic mismatches, and response delays early in the development and validation cycle.

This system is suitable for automotive instrument clusters, infotainment HMIs, commercial vehicle dashboards, and industrial HMI panels, and can be used across R&D, validation, and production testing environments. By enabling structured and automated validation, it improves product quality, reduces testing time, and minimizes field-level failures.

Applications

Automotive Instrument Cluster Validation

The HMI Validation System is used to test and validate automotive instrument clusters in real-time by simulating CAN bus messages that mimic actual vehicle conditions. This allows engineers to verify that all gauges, warning lights, indicators, and digital displays respond correctly under various scenarios such as acceleration, braking, engine start/stop, and fault conditions. By providing a controlled and repeatable CAN environment, the system ensures accurate functional validation without the need for a running vehicle, enabling early detection of logic errors, display mismatches, or delayed responses. This accelerates development, reduces testing time, and guarantees that the instrument cluster meets OEM quality standards before deployment.
