[0019] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] The utility model proposes an automatic driving vehicle simulation test device, see Figure 1-Figure 5As shown, it includes a runway 1, a traction platform 2, a roller 21, a support platform 22, a vertical track 3 and a road condition test component. The vertical track 3 is embedded on the left side of the runway 1, and the traction platform 2 is mounted on the vertical track 3. The corners of the top of the traction platform 2 are set in an oblique shape, which can effectively avoid collision with the wheels of the automatic driving vehicle 10, so that the automatic driving vehicle 10 can pass smoothly over the traction platform 2. The bottom of the traction platform 2 is provided with rollers 21 adapted to the vertical track 3. The traction platform 2 is provided with slots 20 at intervals. The slots 20 are plugged with support platforms 22 for carrying vehicle models a, human models b and cargo models c. The support platform 22 is made of environmentally friendly foam material, is lightweight and can be recycled, which is beneficial to reducing the cost of use. The automatic driving vehicle 10 is parked on the right side of the runway 1, and a road condition test component is set in the middle of the runway 1. The road condition test component can be used to simultaneously perform vehicle performance simulation tests of different scenarios on the automatic driving vehicle 10, which is beneficial to comprehensive testing of the performance of the automatic driving vehicle.

[0021] For further information, see Figure 1 and Figure 2 As shown, the road condition test component includes a transverse track 4, an oblique track 5 and an arc track 6. The middle part of the runway 1 is embedded with a transverse track 4 perpendicular to the vertical track 3, the front side of the middle part of the runway 1 is embedded with an oblique track 5, and the rear side of the middle part of the runway 1 is embedded with an arc track 6. The transverse track 4, the oblique track 5 and the arc track 6 are all equipped with a traction platform 2 and a roller 21. The transverse track 4 is used for a human model b to perform a simulation test of crossing the runway 1. By controlling the speed at which the traction platform 2 on the transverse track 4 moves out, the driving scene of the automatic driving vehicle 10 suddenly appearing on the runway 1 during normal driving can be truly simulated, and the oblique track 5 and the arc track 6 are used for the vehicle model a to perform a lane change simulation test, which is beneficial to provide a complex and realistic road condition environment for the automatic driving vehicle 10.

[0022] In addition, see Figure 3 As shown, there is a gap between the top of the traction platform 2 and the chassis of the autonomous driving vehicle 10, so that the height of the traction platform 2 itself is lower than the height of the chassis of the autonomous driving vehicle 10 from the ground, so that the autonomous driving vehicle 10 can pass over the traction platform 2 without causing damage to the traction platform 2 and the autonomous driving vehicle 10.

[0023] By respectively assembling the vehicle model a, the human model b and the cargo model c on the traction platform 2 at the vertical track 3, and by controlling the moving speed of the traction platform 2, it is possible to respectively simulate the vehicle normally traveling on the runway 1, and simulate the pedestrians who may pass by at any time or the cargo that suddenly falls on the runway 1; and when the automatic driving vehicle 10 is traveling normally, by releasing the traction platform 2 equipped with the human model b on the transverse track 4, it is possible to vividly simulate the pedestrians who suddenly cross the road, and by releasing the vehicle model a assembled on the traction platform 2 on the oblique track 5 and the curved track 6, it is possible to realistically simulate the vehicle that suddenly changes lanes on the road. In this way, the above scenarios are conducive to simultaneously conducting multiple complex road condition tests on the automatic driving vehicle 10, and thus are conducive to improving the accuracy of the performance test data of the automatic driving vehicle 10. Moreover, the vehicle model a, the human model b and the cargo model c can all be replaced by environmentally friendly foam or inflatable bags, and will not cause damage to the automatic driving vehicle 10, and thus are conducive to greatly saving the performance test cost of the automatic driving vehicle 10.

[0024] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
