Whole vehicle hardware-in-loop test method, device and system

Abstract

The invention discloses a whole vehicle hardware-in-loop test method, device and system. The method is suitable for a scene in which a static test vehicle is tested by controlling a target vehicle torun in a closed test field, and is characterized by, through a user, configuring driving track points of two vehicles and driving time of two adjacent points on a map of a closed test site; based on the relationship among the distance, the time, the speed and the acceleration and the relative movement of the two vehicles, generating relative driving track point sequence data of a target vehicle driving relative to a test vehicle, taking the data as test track point sequence data, and issuing the test track point sequence data to the target vehicle in batches to make the target vehicle drive according to the data received batch by batch; and finally, under the condition that the matching result of the test track point sequence data received by the target vehicle and the actual track point sequence meets a preset matching condition, storing the test result of the target vehicle as the test result of the test vehicle. According to the invention, the driving of the target vehicle can be accurately controlled to realize the objective evaluation test of the test vehicle.

Description

technical field [0001] The invention relates to the field of closed testing of intelligent networked vehicles, in particular to a method, device and system for hardware-in-the-loop testing of a complete vehicle. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] With the advancement of intelligent network technology, the objective evaluation of intelligent network vehicles or related intelligent products is more and more urgent. At present, some existing evaluation methods based on specific conditions have failed to test the complex performance of intelligent network connection. Therefore, a test method between virtual test and real vehicle road test is needed. The vehicle hardware-in-the-loop test system based on the closed test site is the tool chain for the complete test of ...

Problems solved by technology

[0004] However, at present, the domestic technology in the field of vehicle hardware in-the-loop system is still immature. The existing technology is mainly based on the virtual model to realize the in-the-loop test of the vehicle, which is difficult to reflect the real vehicle driving state, and lacks precise control of the test process. Meet the needs of objective evaluation

The technology in this aspect is very complicated, the construction cost is very high, and there is no relevant experience in China
