Simulation device and device set capable of adjusting and controlling concave-convex degree of road surface

Abstract

The invention discloses a simulation device and device set capable of adjusting and controlling the concave-convex degree of a road surface belongs to the field of automobile testing, and aims to provide traffic road scenes of various road surfaces with different concave-convex degrees in automobile driving simulation. A bearing is mounted in a bearing seat supported by a support frame; the circumferential surface of one section of the top end of a sleeve is installed in an inner ring of the bearing; the inner circumferential surface of the sleeve is provided with internal threads; the circumferential surface of one section of the bottom end of the sleeve is provided with a gear ring formed by teeth meshed with a gear; a road plate is laid on the top end face of a threaded supporting column; external threads matched with the internal threads of the sleeve are arranged on the periphery of the threaded supporting column; the sleeve rotates in two opposite directions to adjust the depth of the threaded supporting column located in the sleeve due to threaded connection, so that the height of the threaded supporting column between the bearing seat and the road plate is adjusted. As manydrive test environments as possible can be provided for driverless automobiles.

Description

technical field [0001] The invention belongs to the field of automobile testing and relates to a device capable of adjusting and controlling road surface obstacles. Background technique [0002] In recent years, the development of unmanned vehicles and their corresponding detection techniques have become hot issues. With the continuous integration of various technologies in unmanned vehicle technology, and the increasing intelligence and complexity of unmanned vehicles, more efficient and comprehensive detection devices are required. When a driverless car is tested on a real road, it is an important part of the test to deal with various emergencies. Among them, the ability of unmanned vehicles to avoid obstacles and safely handle road emergencies is particularly important. The existing theoretical research on unmanned vehicle road testing has been very in-depth, and the actual research and development is not mature enough. Continuous testing is needed to verify and improve ...

AI Technical Summary

Problems solved by technology

However, this solution also has some problems: because real vehicles, radars, cameras, etc. are required to implement, the cost of equipment is relatively high, and a large number of test sites need to be provided. In the case of immature control algorithms, real vehicle experiments have certain risk, and the development cycle is longer

When testing unmanned vehicles on roads with different bumps and bumps, only obstacle simulation devices with corresponding bumps and bumps can be manufactured separately, which is time-consuming, labor-intensive and inconvenient, and the available vehicle performance data is relatively small, which cannot be done well. Test the real-world performance of self-driving cars
