Simulation test system and method

Abstract

The invention provides a simulation test system and method, and the method comprises the steps: enabling a driving simulator to control the driving of a virtual vehicle, and transmitting a control signal of the virtual vehicle to a simulation machine; the vehicle dynamics model performs modeling on a virtual vehicle according to the control signal, and vehicle information obtained after modeling is sent to the scene simulation module; and the scene simulation module constructs an automatic driving scene of the virtual vehicle according to the control signal and the vehicle information, and sends the recorded steering wheel angle and camera data when the virtual vehicle runs in the automatic driving scene to the deep learning tool, so that the deep learning tool trains the initial model according to the received data to obtain a test model. According to the mode, braking control over the virtual vehicle can be achieved, and the automatic steering function of the virtual vehicle can be achieved through the camera data provided by the scene simulation module, the test model and the vehicle dynamics model. In addition, the closed-loop simulation test of the scene, the dynamic model and the test model can be realized through joint simulation.

Description

technical field [0001] The invention relates to the technical field of automatic driving testing, in particular to a simulation testing system and method. Background technique [0002] It is difficult to cover various working conditions, especially complex special working conditions and dangerous working conditions, in the actual vehicle site used for automatic driving function testing. Moreover, the real vehicle test site has the problems of long test time, single scene elements, and limited resources. These problems undoubtedly limit technology development and iteration. Virtual simulation test technology is an important supplement to the real vehicle test scene, and the virtual simulation test system has also become the only way for autonomous driving research. [0003] At present, the virtual simulation test technology of autonomous driving is mainly oriented to the perception-planning-control sequential technical architecture, which mainly includes many modules such a...
