mk-motion in vehicle development
Instrument cluster, head unit, turn signals, headlights, actuators – multiple cameras, synchronous recording. mk-motion relieves the burden of hours-long immunity sweeps: anomalies are automatically detected and assigned to the test parameters.
The challenge
A typical immunity sweep according to ISO 11452 or manufacturer-specific standards runs for several hours – frequency by frequency, level by level, for various operating states. Simultaneously, the instrument cluster, head unit, exterior lighting, windshield wipers, and other actuators must be monitored. No test engineer can reliably keep track of all of this for the entire duration of the test.
To make matters worse, many errors are subtle and short-lived. A display that freezes for 200 ms. A turn signal that skips a cycle. A warning light that flickers briefly. If the deviation is not detected the moment it occurs and assigned to its exact frequency, it is virtually impossible to reproduce for development purposes.
What mk-motion is doing here
16 cameras, one synchronous protocol. Instrument cluster, head unit, taillight assembly, overall view – four HD streams, or 16 streams at 540p with hardware merging, are recorded and analyzed simultaneously. No switching, no missing..
Blinker frequency, needle position, display content – all in one evaluation. Period and reference signal measurement monitors turn signals. Gauge recognition reads analog instruments. Differential image detection identifies display malfunctions. OCR reads text or numerical values. Pipeline blocks exist for all typical scenarios to support the engineer in the evaluation. Each ROI has its own pipeline, tailored to the monitored element.
Combiner for complex valuations. Alarm only when the speedometer needle twitches AND the LED is affected? Suppress alarm when a specific operating state is active? The combiner logically links ROI results – without external scripting, unless you want it.
Anomalies are automatically assigned to the test parameters. The EMC test software transmits frequency, level, and modulation in real time. Every alarm in the log can be assigned to the exact test condition – the developer can reproduce it precisely.
Hours of testing, complete documentation. Triggered recording with pre-buffer saves only the relevant sequences. At the end of the test day: a structured event list instead of hours of raw footage – as the basis for the engineer's evaluation.
