Abstract

The invention discloses an automatic driving virtual test platform building method for mapping real-world road conditions. The method comprises the following steps of: acquiring real-world road condition information; establishing a road environment module for mapping real-world road conditions; constructing an automatic driving vehicle module and an interactive vehicle module; integrating the roadenvironment module, the automatic driving vehicle module and the interactive vehicle module to realize information interconnection, and building an automatic driving virtual test platform capable ofmapping real world road conditions. According to the method, the running state of the automatic driving vehicle under the real world road conditions can be rapidly tested, and an interactive vehicle running track, a automatic driving perception sensor model and an automatic driving function model can be conveniently adjusted so as to meet the requirements of different automatic driving test working conditions.

Description

technical field [0001] The invention belongs to the technical field of virtual testing of automatic driving, and relates to a method for building a virtual testing platform of automatic driving for mapping real-world road conditions. Background technique [0002] Due to the inexhaustible number of unknown test road traffic scenarios, compared with the virtual test method of autonomous driving, the test site or public road test method based on real vehicles has the disadvantages of long test period, uncontrollable test scene, limited manpower and material resources, and unguaranteed test safety. technical bottleneck. Therefore, virtual simulation testing has become an important substitute for real physical testing of autonomous driving under constrained economic conditions, and the virtual test platform is also an important tool for research related to autonomous driving. [0003] The road traffic system is a nonlinear complex system that is coupled among human-vehicle-road-...
