vehicle_state_log

Vehicle State Log

The vehicle state log parses eCal messages from the "vehicle_dynamics" topic, aggregates them with the Ankaios workload states information as well as vehicle ID and publishes them together via an MQTT "vehicle/vehicle_dynamics" topic.

For this workload to publish messages, you need either live eCal data or feed it via ecal_play. Example: "ecal_play -m measurements/2024-11-19_15-45-14.870_measurement"

Example of one message at a given timeframe:

Development

The restart-shift2sdv script provides a very quick and convenient way to develop the application is short cycle. [!Note] Before running the application, the MQTT broker has to be up and running under the IP specified in the env var inside "shift2sdv_manifest.yaml"!
