Hybrid Vehicles Challenge: Multiple Variants
Environment Restbus- and
Simulation values Evaluation
Env. Temperature
Env. Humidity
Device Temperatures
Device States
Challenge solved by reading parameter values dynamically from ECU Data sets!!!
Process
1. Read parameters (e.g. threshold value) via calibration software
2. Parameterize the test globally with these values (e.g. cooling demand)
3. Implement values (e.g. temperatures, test evaluation) based on the read parameter
