Abstract

The invention relates to the technical field of automobile function testing, in particular to a finished automobile automatic driving function simulation testing system and testing method. The systemcomprises an upper computer which is used for building an initial simulation testing scene and displaying an updated simulation testing scene, a test host for receiving the initial simulation test scene data, simulating state information of a vehicle and a target object, and updating the simulation test scene according to the state information output by a test vehicle, the test vehicle for receiving the state information of the vehicle and the target object, and outputting a corresponding control instruction and the vehicle state information after execution of the control instruction, and a wheel hub driving platform for fixing the vehicle, guaranteeing the rotation of wheels, and driving the test vehicle to execute corresponding actions according to the control instruction output by the test vehicle. Joint simulation is carried out based on a hub driving platform, a test cabinet and simulation software, and problems of space limitation and dynamics of a real vehicle in a real vehiclesimulation test are effectively solved.

Description

technical field [0001] The invention relates to the technical field of automobile function testing, in particular to a vehicle automatic driving function simulation testing system and testing method. Background technique [0002] In order to ensure the rationality of the logic control of the ADAS controller and the automatic driving controller of the vehicle, it is necessary to use simulation methods to carry out simulation tests on the vehicle loaded with the ADAS controller and the automatic driving controller to verify its functional response and optimize the algorithm logic. At present, the ADAS / autonomous driving function simulation test technology for the whole vehicle has its limitations. For example, in the previous simulations, the motion state of the main vehicle was changed or the state of the target object in a single test scene remained unchanged (cannot be accurately calculated), and the main vehicle could not make a timely response speed test to the real-time ...
