Description

Technical Field

[0001] The utility model relates to the technical field of automatic driving adjustable fixation, and in particular to an automatic driving adjustable fixation device. Background Art

[0002] During the full-vehicle rotary test in the environmental chamber, the test driver is required to precisely control the test vehicle's speed to meet the relevant test standards. Most vehicles in the environmental chamber require a constant-speed run-in before the actual test. The range reduction method also involves long-duration constant-speed driving conditions. These conditions require no additional driver input, but they do require the vehicle's speed to be maintained at a constant value for extended periods, which can be quite demanding on the driver's energy.

[0003] Market research and analysis show that there are relatively few experimental auxiliary equipment for this type of experimental conditions. There is no self-driving adjustable fixture on the market that is fully suitable for indoor hub tests. Although the existing self-driving robots for indoor hub tests on the market can complete the driving tracking of the test curve and meet the required experimental requirements, the self-driving robots are complex in structure and expensive, and their direct application in indoor hub tests is not cost-effective. With the rapid development of new energy vehicles and intelligent connected vehicles, the demand for vehicle running-in and driving range testing is strong. Most of the leg-type driving robots currently on the market need to occupy the main driver's seat and cannot be well adapted to the relevant testing needs of environmental chambers.

[0004] Therefore, it is necessary to design a cost-effective automatic driving adjustable fixing device suitable for indoor rotating hub test, which can fix the steering wheel and accelerator pedal to alleviate the driving fatigue of the experimental driver under constant speed driving conditions.
