Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned vehicles, and in particular relates to a slope climbing test device for an unmanned vehicle. Background Art

[0002] An unmanned vehicle is an intelligent vehicle that mainly relies on an intelligent driving system based on a computer system inside the vehicle to achieve unmanned driving. Unmanned vehicles integrate many artificial intelligence technologies such as automatic control, environmental interaction, and visual recognition. They are the product of the high development of computer science, pattern recognition, and intelligent control technology.

[0003] During the hill climbing test of unmanned vehicles, a hill climbing test device is required. Currently, the ramp angles on the hill climbing test devices are mostly fixed, so that the vehicle can only be tested at a specified angle. When different slope tests are required, the test device needs to be replaced, which makes it unable to meet the needs of hill climbing tests for different vehicles and reduces its practicality. Secondly, during the test, the center of gravity of the device increases, which is prone to shaking or even tipping over, posing a great safety hazard. Therefore, we provide a hill climbing test device for unmanned vehicles. Utility Model Content
