Simulation driving platform for hardware-in-the-loop simulation test

Abstract

The invention relates to a simulation driving platform for a hardware-in-the-loop simulation test, which comprises a simulation cockpit and a six-degree-of-freedom motion platform, and is characterized in that the six-degree-of-freedom motion platform comprises a lower support base, an upper motion platform, six power arms and twelve universal hinges, and the simulation cockpit is arranged on theupper motion platform; the lower supporting base is located below the upper motion platform. The six power arms are arranged between the lower support base and the upper motion platform, and the upperend and the lower end of each power arm are hinged to the upper motion platform and the lower support base through the universal hinges. Vibration of a vehicle body engine and bumping of road conditions can be simulated perfectly, the driving environment and the moving posture of an automatic driving vehicle can be simulated visually and truly, the test simulation driving effect is good, and hardware-in-the-loop simulation test with higher performance can be met.

Description

technical field [0001] The invention relates to simulated driving equipment, in particular to a hardware-in-the-loop simulation test simulated driving platform. Background technique [0002] With the development of intelligent technology, automatic driving has become a major direction for the development of automobile technology. The performance requirements of automobile driving simulation systems are getting higher and higher, and high-performance driving simulation systems need economical and applicable simulation driving platforms to better meet the test requirements. requirements to improve testers' experience in testing the developed driving system. [0003] Some existing simulated driving platforms, for example, in the utility model patent published by the State Intellectual Property Office with the application number 201320805134.1 and the name of the invention is a simulation car driving training device, the seat is set above the seat platform through six hydraulic ...

[0003] Some existing simulated driving platforms, for example, in the utility model patent published by the State Intellectual Property Office with the application number 201320805134.1 and the name of the invention is a simulation car driving training device, the seat is set above the seat platform through six hydraulic cylinders , can simulate realistic vehicle driving with a high degree of simulation, but only set the degree of freedom movement on the seat, the seat and the monitor do not move synchronously, and the simulated driving operation platform occupies a large area

[0004] There are also some simulated driving platforms that are supported by three or four rods. For example, in the utility model patent published by the State Intellectual Property Office with the application number 201521029441.0 and the invention name being a simulated driving simulation platform, the transmission mechanism can drive the upper installation platform and The display moves up and down together, and the simulation effect is good, but the degree of freedom of the platform is low, and the transmission mechanism can only drive the upper installation platform and the display to move up and down together, and the test experience needs to be improved

[0005] In addition, in the invention patent application published by the State Intellectual Property Office, the application number is 201910058976.7, and the invention name is the in-the-loop simulation calibration system and calibration method of the vehicle controller. By combining the six-freedom platform and the in-the-loop simulation system, you can Make the vehicle controller simulation to be calibrated in a real driving simulation scene. This patent provides a calibration system and calibration method, but does not give a construction plan for the relevant simulation driving platform, so further improvement is still needed

In the invention patent published by the State Intellectual Property Office, the application number is 201710322350.3, and the invention name is an electric vehicle layered control system hardware-in-the-loop test platform and test method, which can realize the closed-loop control of "human-vehicle-road" The system conducts hardware-in-the-loop testing, but the simulated driving platform cannot simulate the real vehicle experience well
