Abstract

The invention discloses a VIL test platform based on a VTS. The VIL test platform comprises a real vehicle, a real-time simulation system and a virtual scene simulation platform. Firstly, a functional scene realized by a tested controller is built in a virtual scene simulation platform, then a corresponding sensor model is built in the virtual scene simulation platform according to an input signal required by a tested object, and information is sent to a real-time simulation system. And the real-time simulation system carries out real-time positioning on a real vehicle integrated by the tested controller and a virtual vehicle projected in a virtual simulation scene of the virtual scene simulation platform, and the tested control algorithm feeds back an output signal to control the action of the real vehicle, so that the controller with the automatic driving algorithm is verified. According to the invention, control and monitoring of each signal are realized, and IO resources and the like required by the tested node can be expanded and provided. The control of the automatic driving simulation test is more efficiently realized, and the function of the automatic driving algorithm is more comprehensively verified.

Description

technical field [0001] The invention relates to the technical field of test platforms, in particular to a VTS-based VIL test platform. Background technique [0002] The VT System system is a product of the German Vector Automotive Electronics Company. The VT System (hereinafter referred to as "VTS") is a real-time simulation system. It is a modular hardware system and is part of the execution hardware of this system. It can realize the control and monitoring of power signals, network fault injection, and expandable IO resources required by the nodes under test. Modular design, flexible configuration, plug and play, it also combines functional testing of ECU (Electronic Control Unit, electronic control unit) and vehicle network system, flexible, real-time and editable. [0003] At present, autonomous driving is beginning to move towards real commercial applications, but it needs to go through a lot of repeated tests before it can meet the commercial requirements. It is unim...
