Canonsburg-based ANSYS Inc. (NYSE: ANSS) and Lawrenceville-based Edge Case Research announced an agreement Tuesday to integrate their respective autonomous vehicle technologies — ECR’s artificial intelligence perception stress testing and risk analysis system Hologram with ANSYS’s autonomous vehicle simulation technologies. Hologram collects real-world data and picks out the “tough spots” where AVs have trouble. ANSYS’s technologies can then run in-depth simulations on those edge cases, or unusual road situations a self-driving vehicle might encounter. “Edge Case Research has an interesting offering that complements what ANSYS has to offer in a very positive way,” Sandeep Sovani, director of the global automotive industry at ANSYS, said.
