Problems solved by technology

Such a hardware-in-the-loop test system cannot allow traditional OEMs to estimate the overall function and performance safety of the vehicle before the vehicle is put on the road. It still needs to conduct uninterrupted closed road tests on vehicles in various complex traffic environments in closed test areas. Test t

Abstract

The invention relates to an indoor complete vehicle hardware-in-loop test device, which comprises a test tested vehicle, a rotary hub platform, an AGV movable target vehicle, anindoor positioning system for realizing accurate positioning of the test tested vehicle and the AGV movable target vehicle, a virtual target object system with a radar on a ring screen, an environment simulation system forrealizing a simulation environment, avirtual navigation simulation system for realizing a virtual navigation environment of the test tested vehicle, aV2X signal simulation system for providing a virtual scene, and an integrated control system for realizing low-delay data circulation among the systems and terminal control. Compared with the prior art, the devicehas the advantages of high controllability, high efficiency, high repeatability and the like.

Description

technical field [0001] The invention relates to the field of hardware vehicle hardware-in-the-loop testing, in particular to an indoor vehicle hardware-in-the-loop testing device. Background technique [0002] Hardware-in-the-loop test simulation, also known as hardware-in-the-loop test simulation, is a simulation system that puts part of the system hardware that needs to be simulated directly into the simulation loop. It not only makes up for many defects in digital simulation, but also improves the confidence of the entire model. And can greatly reduce the workload of programming. Another advantage of this kind of simulation is that it realizes the real-time data interaction between the simulation model and the timing system, which makes the verification process of the simulation results very intuitive and greatly shortens the product development cycle. During the simulation, the computer and the actual hardware are connected through various information channels, and the ...
