Description

Technical Field

[0001] The invention relates to the field of driving tests, in particular to an automatic tilting device for a traffic object simulation body used for unmanned driving tests. Background Art

[0002] An unmanned car, also known as an autonomous car or driverless vehicle, is a car that can drive autonomously without the intervention of a human driver. This technology utilizes a variety of sensors, algorithms, and communication technologies to enable the car to sense the surrounding environment, plan paths, and control driving. However, in order to improve the driving data of unmanned cars, it is necessary to use a closed test site, use various test equipment, and related traffic object simulations to build real traffic scenes for related unmanned driving tests and experiments, so that the car can achieve the desired effect. During the test, in order to better simulate the collision effect of the human body, dummies are usually used as simulations. However, when pedestrians cross the road, they have a certain inclination. In order to achieve better test results, it is necessary to design an automatic tilting device to meet the test requirements.

[0003] An existing automatic tilting device for a traffic simulation body used for unmanned driving tests is provided with a group of towing platforms, a pulley is provided at the bottom of the towing platform, a pull belt is provided at one side, and a clamping device fixed by bolts is provided on the top of the towing platform. When it is necessary to perform a test through the automatic tilting device for the traffic simulation body, it is necessary to first install a dummy on one end of the clamping device through a fixing rod, and then adjust the tilting angle of the clamping device through bolts. After the angle is adjusted, the clamping device and the dummy are fixed through the bolts, so that the dummy can have a certain tilting angle, so that the test can achieve better test results.

[0004] However, for the existing automatic tilting device for traffic simulation body used for unmanned driving test, the clamping device is fixed by bolts, which is cumbersome to operate and affects the practicability of the device. In addition, the dummy is directly installed on the clamping device by a fixing rod. When the dummy collides with the unmanned vehicle, it will be stuck, so that the fixing rod may break or the dummy may not be knocked away, which affects the test effect and reduces the practicability of the device. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide an automatic tilting device for a traffic simulation body used for unmanned driving tests, so as to solve the technical problem that the existing automatic tilting device for a traffic simulation body used for unmanned driving tests has poor performance.
