Abstract

The invention relates to the field of automatic driving, and discloses a simulation system and a test platform for a pilotless automobile. The test method comprises the following steps: generating a vehicle simulation environment; reading sensor data in the simulation environment through a data conversion interface and converting the sensor data into sensor data which can be identified by a secondautomatic driving simulation system; enabling the second automatic driving simulation system to receive the recognizable sensor data, generating a second control instruction according to the recognizable sensor data and a set test target, and sending the second control instruction to the data conversion interface; enabling the data conversion interface to receive the second control instruction and convert the second control instruction into a control instruction which can be identified by the simulation environment generation module; and enabling the simulation environment generation module to apply the recognizable control instruction to a virtual vehicle to cause the virtual vehicle to run in a virtual scene. In this way, testing of the second automatic driving simulation system is achieved.

Description

technical field [0001] The invention relates to the field of automatic driving, in particular to a simulation system and a test platform for unmanned vehicles. Background technique [0002] The development of autonomous driving systems follows the process from simulation to real vehicle testing. As a zero-risk, fast iterative, and reproducible testing method, simulation experiments have laid a solid foundation for road testing of autonomous driving technology. Simulation can quickly and effectively test the correctness and performance of the algorithm. [0003] The development of the current main robot system depends on Ros (robot operating system). Ros is an open standard platform that provides a series of software frameworks and tools to help software developers create robot application software. Ros is mainly attached to the Linux operating system. If the simulation of the whole process is carried out under Linux, it takes a lot of time and effort to build the basic wo...
