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

Abstract

The invention discloses a vehicle hardware-in-the-loop test method, device and system, which are suitable for the scene where a stationary test vehicle is tested by controlling the driving of a target vehicle in a closed test site. Configure the driving trajectory points of the two vehicles and the driving time of the two adjacent points, and then based on the relationship between distance, time, speed, acceleration, and the relative motion of the two vehicles, generate the relative driving trajectory point sequence data of the target vehicle relative to the test vehicle, As the test track point sequence data, it is sent to the target vehicle in batches, so that the target vehicle drives according to the data received batch by batch; finally, the matching result of the test track point sequence data received by the target vehicle and the actual track point sequence satisfies the preset If the condition is matched, the test result of the target vehicle is saved as the test result of the test vehicle. The invention can accurately control the driving of the target vehicle 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 ...
