Abstract

The invention discloses a driverless vehicle environment simulation test system. The system comprises an environment simulation system and a test system; the environment simulation system is used for establishing a real road environment model for a driverless vehicle and simulating the real road environment for the driverless vehicle; during test, the real road environment model for the driverless vehicle is converted into a task form file, and the task form file is input to a driverless vehicle-mounted control computer, wherein the task form file consists of three-dimensional world geodetic system1984 (WGS84) coordinates of each guide point of a driverless vehicle passing test road section and environmental element codes of the guide points; and the driverless vehicle-mounted control computer sends signals of the three-dimensional WGS84 coordinates of each guide point of the driverless vehicle passing test road section and the environmental element codes of the guide points to a tester held multifunctional box through a vehicle-mounted antenna in the test process, and the tester held multifunctional box receives and displays the signals.

Description

technical field [0001] The invention relates to the technical field of unmanned vehicle testing, in particular to a method that can establish various real road environment models by combining various environmental elements to realize accurate simulation of complex real environments, and test unmanned vehicles in the simulated environment. Performance unmanned vehicle test system and test method. Background technique [0002] The intelligent behavior test of unmanned vehicles in complex environments is an important task in the development process of unmanned vehicles, and it is an important means to realize the scientific evaluation of the research level of key technologies such as environment perception and behavior decision-making of unmanned vehicles.
