HONGKE Solution] Toward High-Level Autonomous Driving Verification: HONGKE's High-Fidelity HIL Simulation Solution Reinvents Test Value

along with L3 / L4 Autonomous Driving TechnologyContinued development has seen a rapid increase in the density of sensor configurations in vehicles and an exponential increase in the complexity of test scenarios. At the same time, theHIL (Hardware-in-the-Loop) TestingWe are facing a number of key challenges, such as insufficient simulation fidelity of traditional solutions to meet the demands of high-end self-driving sensing systems; higher upgrade costs due to the complex system link structure; the increasingly obvious contradiction between insufficient edge scene coverage and low-latency data transmission; and the difficulty of the existing test framework to support the full-life-cycle testing and validation of high-level intelligent driving systems.
