Automotive Modeling Challenges
Challenge 1
- Explore the design architecture to account for a time-varying channel as vehicles move in their environment.
-PAIN: Simulation does not account for the time-varying nature of a channel, or parameters such as propagation loss and doppler shifts, which vary over time.
-SOLUTION: The SystemVue and STK integrated virtual platform enables dynamic co-simulation analysis. STK provides dynamic 3D scenarios, while SystemVue provides sophisticated Tx/Rx modules.
Challenge 2
- Evaluate design solutions for different driving scenarios.
-PAIN: It’s difficult, and sometimes not even possible, to incorporate the vehicle’s environment (e.g., rural, urban, or highway scenarios) into design analysis
-SOLUTION: With SystemVue and the STK dynamic channel environment characteristics, many types of automotive driving scenarios and communication links, like Vehicle-to-Vehicle (V2V) and Vehicleto-Infrastructure (V2I), can be included in simulation.
Challenge 3
- Include the antenna’s physical effects (e.g., the antenna gain pattern) in the system design
-PAIN: A mounted vehicle antenna pattern differs from that of an unmounted antenna pattern because of the effects of the car’s body
-SOLUTION: SystemVue antenna gain patterns, coupled with vehicle location information provided by STK during simulation, enable a precise accounting of the antenna pattern effects on the communication system’s performance.
