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 ...

AI Technical Summary

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 to get first-hand information about the vehicle as a whole

This increases the test cost and greatly increases the test cycle, and its hierarchical and hierarchical tests for the controller MCU, battery module (BMS), radar, camera and related components, etc. cannot intuitively reflect the vehicle ADAS function Execution
