Description

Technical Field

[0001] The invention relates to the technical field of simulated vehicles, in particular to a simulated vehicle. Background Art

[0002] With the development of science and technology, artificial intelligence technology has been gradually applied. Self-driving vehicles have also been gradually seen by the world with the advancement of science and technology, and some leading organizations have begun to apply them to the fields of personnel transportation, logistics, sanitation, security, etc.

[0003] In order to ensure the functionality and safety of the applied technology, a large number of repeated experiments are required for specific scenarios, such as the scenario where an autonomous vehicle encounters other vehicles. This requires providing autonomous vehicles with simulation vehicles that can meet the test requirements to participate in the test.

[0004] Most of the existing simulation vehicles used for obstacle avoidance tests are inflatable simulation vehicles. The characteristics of inflatable simulation vehicles are that they are made of PVC (PolyVinyl Chloride) mesh cloth, and they need to be inflated for 20 minutes with an AC blower before use, and then the inflated simulation vehicle is transported to various test sites. After the test is completed, the air in the simulation vehicle is extracted with a blower, and the simulation vehicle is folded and put into a bag. The entire operation process requires at least two operators, and the strength of the operators is required.

[0005] At present, the simulation vehicles on the market that simulate vehicles for obstacle avoidance testing mainly have the following problems:

[0006] 1. It is large in size and weight. It is 1 cubic meter when not inflated, which often requires another vehicle to assist in transportation. After arriving at the target location, at least 2 people are required to carry it, which greatly increases the testing cost.

[0007] 2. The use conditions are limited because of the need for inflation. Even with a standard AC blower, it takes 20 minutes and the inflation process is noisy. If a handheld blower with its own battery is used, the inflation time is too long due to the low power, and the air extraction and bagging also consumes electricity, which often requires a blower.

[0008] 3. The layout of the test site is inconvenient. The inflatable simulation car is inconvenient to move and requires at least two people to carry it. After being used for a period of time, the body of the car will easily become soft due to lack of air. When the two people are carrying the car, the friction with the ground will cause damage to the device. Summary of the invention
