Driverless automobile virtual test platform

Abstract

A driverless automobile virtual test platform comprises a driverless simulation system, a virtual driverless test automobile, a data management module, a simulation control module and an interface calling module. The driverless simulation system is used for simulating the driving process of the driverless vehicle in the virtual environment according to the test requirement of the user on the virtual driverless test vehicle. The data management module is used for managing an automobile model and a scene model in the virtual test platform and comprises a test scene database, an automobile modeldatabase and a simulation control database. The simulation control module is used for binding corresponding motion parameters to the automobile model and establishing an unmanned virtual automobile dynamic model. The interface calling module comprises a system interface, a vehicle model switching interface, a scene switching interface and a parameter display interface. On the premise that the performance of the pilotless automobile is not affected, field testing is partially replaced, method and theoretical guidance are provided for field testing, the development period is shortened, and fundsare saved.

Description

technical field [0001] The invention belongs to the field of unmanned driving by bicycle, and in particular relates to a virtual test platform for unmanned vehicles developed with a Unity3D engine. Background technique [0002] Automobile driverless technology can greatly improve the efficiency of the transportation system and the safety of people's travel. In order to realize the development of driverless technology from the laboratory to mass production and ensure that the mass-produced driverless cars can run normally, it is necessary to It conducts a large number of road tests, some of which have harsh environmental conditions, and many field tests are time-consuming and require a lot of manpower and material resources. With the continuous development of virtual reality technology, the software technology has gradually matured, which provides a strong technical guarantee for the development and application of the car virtual test system, making it possible to use the vir...
