Problems solved by technology
However, closed-site testing is expensive, the simulation method is simple, and has little reference value; while real-road testing is more realistic, it is prone to accidents, has high potential safety hazards, and is restricted by law.
Therefore, there is currently no testing mechanism that satisfies the requirements and is safe and reliable.

The invention discloses a traffic object simulation device used for intelligent connected vehicle testing. The traffic object simulation device comprises an all-terrain robot, a supporting bench, a traffic object model, a first traffic object attitude adjustment mechanism and a second traffic object attitude adjustment mechanism, wherein the supporting bench is provided with an L-shaped connectingframe and an external platform assembly, and the external platform assembly comprises a platform panel; the traffic object model is supported above the platform panel and comprises a figure model with adjustable height, and an animal model; the first traffic object attitude adjustment mechanism is used for controlling the left and right shoulder joints and the left and right knee joints of the figure model with the adjustable height to carry out cyclic activity to simulate the gait of a pedestrian; and the second traffic object attitude adjustment mechanism is used for controlling the four-limb joints of the animal model to carry out cyclic activity to simulate the gait of the animal. The test platform provided by the embodiment of the invention can change participation objects and environments, a convenient condition is provided for simulating the test of any traffic scene, and the test functions of low cost, zero risk, multiple traffic objects and multiple scenes are realized.
Description
technical field [0001] The invention relates to the technical field of automatic driving testing, in particular to a traffic object simulation device for intelligent networked vehicle testing. Background technique [0002] In recent years, automobiles and artificial intelligence have gradually become one of the most concerned issues in the industry and academia. In terms of intelligent network connection technology, the entire system has tended to be perfected, with theoretical support and practical engineering applications. However, ICV (English full name is "Intelligent and Connected Vehicles"; Chinese full name is "Intelligent Networked Vehicles") has relatively little research in the testing field, and the system is not perfect, and there is currently no completely unified standard. For vehicles, safety always comes first. Every self-driving intelligent connected car needs to go through a lot of tests from development to commercial use, and these tests can be roughly d...
