The team modeled all sensors, including the photoelectric sensors measuring the attitude of the pod by using digital outputs, the hall switch sensors measuring the velocity by generating PWM signals with varying period times, and the pressure sensors in the brake’s chambers by using analog outputs.
This enabled them to test all the electronic control units. These units read and process sensor data and send commands to the actuators in the pod.
Furthermore, by running their pod model in real-time on the Baseline real-time target machine and connecting their ECU to it, the TUM Hyperloop team verified the pods’ control logic and various safety procedures deterministically and in real-time.
To prove full functionality of the control units, the collected data was verified and checked to determine whether the state transitions and abort criteria work correctly.
