Description

technical field [0001] The invention relates to the technical field related to automobiles, in particular to an unmanned vehicle simulation test device and electronic equipment. Background technique [0002] In recent years, unmanned driving-related technologies have received widespread attention. Since unmanned vehicles often face high risks when testing, hardware reliability, algorithm robustness, and generalization ability for complex environments will have a great impact on the final effect of autonomous driving algorithms; at the same time , since the self-driving algorithm contains multiple modules, the compatibility between each module will also affect the actual use of the algorithm; in addition, testing the self-driving algorithm in some dangerous scenarios has great risk, and will greatly increase the cost of testing. Therefore, before the actual road test, it is necessary to establish a simulator test platform to simulate and analyze the unmanned driving related...
