[0002] In the automotive development process, road testing is a crucial step. It not only provides developers with critical information and data but also verifies the vehicle's performance and reliability in the real world. Compared to laboratory testing, road testing better simulates real-world driving conditions, including various road surfaces and weather conditions. Through road testing, developers can more accurately evaluate various aspects of a vehicle, such as fuel economy, suspension system, braking system, and driving performance.

[0003] For example, Chinese invention patent with publication number CN116106028A provides a special site for testing the misuse of automobile chassis, including a deep pit-type feature road, a raised feature road, and a high ridge-type feature road arranged side by side, as well as a first connecting lane and a second connecting lane. A curved connecting section is provided on the second connecting lane, and the high ridge-type feature road is connected in parallel on the curved connecting section. The first connecting lane and the second connecting lane are located on the left and right sides of the three types of feature roads, respectively.

[0004] However, since most existing test tracks are straight tracks, cars need to make frequent U-turns when conducting tests on different road surfaces, which reduces traffic flow and thus reduces test efficiency. In view of this, a new type of car test track is proposed to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes an automotive proving ground to solve the technical problem mentioned in the background art, which is that most existing proving grounds are straight tracks, requiring vehicles to frequently make U-turns when conducting tests on different road surfaces, thus reducing traffic flow and consequently reducing testing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automotive proving ground, comprising:

[0007] Main body of the site;

[0008] The first circular track is arranged on the main body of the site. One section of the first circular track is a straight section, and the two ends of the straight section are curved tracks. One side of the first circular track is a curved track, and the two sections of the curved track are tangent to the curved track.

[0009] A second circular track is arranged inside the first circular track and follows the same trajectory. A first switching point is provided between the second circular track and the first circular track.

[0010] There are multiple sets of straight running tracks arranged side by side on one side of the straight section inside the second circular running track. A second switching port is arranged inside the second circular running track.

[0011] In a preferred embodiment, the main body of the site is further provided with a site entrance and a loading area.

[0012] In a preferred embodiment, the first circular track is separated from the external area and the second circular track by a first green belt, and the second circular track is separated from its internal area by a second green belt. The first switching port is arranged on the first green belt, and the second switching port is arranged on the second green belt.

[0013] In a preferred embodiment, both the first and second circular tracks are provided with speed bumps at intervals.

[0014] In a preferred embodiment, the first circular track is provided with a track entrance and a track exit that are connected to the main body of the site.

[0015] In a preferred embodiment, the runway entrance is located at the tangent point between the straight section and the curved section of the first circular runway, and the runway exit is located at the straight section of the first circular runway.

[0016] In a preferred embodiment, the inner area of ​​the second circular track includes two sets of circular plazas, which are respectively connected to the two ends of the straight track.

[0017] In a preferred embodiment, the first switching port is provided in two sets, and is respectively arranged at the tangent points of the two sets of arc-shaped tracks and curved tracks on the first circular track.

[0018] In a preferred embodiment, multiple sets of complex road test sections are arranged in both the first and second circular tracks.

[0019] In a preferred embodiment, the first circular track, the second circular track, and the straight track are all equipped with multiple lanes.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] When in use, the test track is configured with a first circular track, a second circular track, and a straight track as test surfaces with different performance characteristics. The straight track can be used as an NVH performance road. A vehicle can perform one performance test on the first circular track and enter the second circular track through the first switching port to perform another performance test. It can also enter the inner area of ​​the second circular track through the third switching port and drive directly into the straight track for NVH performance road testing. The vehicle can also drive circumferentially through the inner area of ​​the second circular track to switch between multiple sets of straight tracks with different specifications. This allows the vehicle to switch between different test sections within the test track without making a U-turn, eliminating weaving sections between vehicles, ensuring smooth traffic flow, and preventing interference between multiple sections, effectively improving test efficiency and data reliability.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0028] Example:

[0029] like Figure 1 , 2As shown, this utility model provides an automobile test track, including a main track 1, an entrance 2 and a loading area 3 arranged on the main track 1, and a first circular track 4 arranged on the main track 1. The first circular track 4 has a straight section at one end and curved sections at both ends. One side of the first circular track 4 is a curved track, and the two curved sections are tangent to the curved track. The first circular track 4 has a track entrance 12 and a track exit 13 that are connected to the main track 1.

[0030] When in use, vehicles can enter the loading area 3 through entrance 2 to wait for testing. During the test, vehicles can enter the first circular track 4 through runway entrance 12 and travel counterclockwise along the first circular track 4. After the test, vehicles can leave the first circular track 4 through runway exit 13. Straight-line and curved driving is permitted on the first circular track 4. The constricted area of ​​the first circular track 4 utilizes reserved open space for building construction or other land use, saving land and intensively utilizing land. The overall pavement volume ratio of the circular test track is over 70%.

[0031] like Figure 1 As shown, in this embodiment, a second circular track 5 is arranged inside the first circular track 4. The second circular track 5 has the same trajectory as the first circular track 4, and a first switching port 8 is arranged between the second circular track 5 and the first circular track 4. Multiple sets of straight tracks 6 are arranged side by side on one side of the straight section inside the second circular track 5, and a second switching port 10 is arranged inside the second circular track 5.

[0032] The first circular track 4, the second circular track 5, and the straight track 6 can be arranged as different test sections. Preferably, the first circular track 4 can be arranged as a rough road durability test section, where vehicles can cycle on the first circular track 4 to conduct rough road durability tests. The second circular track 5 can be arranged as a vehicle durability test section, where vehicles can undergo durability tests. The straight track 6 can be arranged as an NVH performance section, where vehicles can undergo NVH performance tests. During the journey on the first circular track 4, vehicles can enter the second circular track 5 through the first switching port 8, and can also enter the inner area of ​​the second circular track 5 through the second switching port 10 and then drive onto the straight track 6. The first circular track 4, the second circular track 5, and the straight track 6 all have multiple lanes, allowing for simultaneous performance testing of multiple vehicles and improving testing efficiency. Speed ​​bumps 15 are spaced out on both the first circular track 4 and the second circular track 5 to test the vehicle's chassis.

[0033] like Figure 1As shown, in this embodiment, the inner area of ​​the second circular track 5 includes two sets of circular plazas 14, which are respectively connected to both ends of the straight track 6. When a car is being tested on the straight track 6, after leaving the straight track 6, the car can circle around the circular plazas 14 and re-enter the straight track 6, thus eliminating the need for the car to make a U-turn when switching between multiple road segments and improving traffic flow.

[0034] like Figure 1 , 2 As shown, in this embodiment, the first circular track 4 is separated from the external area and the second circular track 5 by the first green belt 7, and the second circular track 5 is separated from its internal area by the second green belt 9. The first switching port 8 is arranged on the first green belt 7, and the second switching port 10 is arranged on the second green belt 9.

[0035] The first circular track 4, the second circular track 5, and the straight track 6 are separated by the first green belt 7 and the second green belt 9. Multiple sets of straight tracks 6 can also be separated by green belts, making it less likely for vehicles to be interfered with by adjacent road sections during testing, thus improving the reliability of test data. The track entrance 12 is located at the tangent of the straight section and the curved track on the first circular track 4, and the track exit 13 is located at the straight section on the first circular track 4. Two sets of first switching ports 8 are provided, respectively located at the tangent of the two sets of curved tracks and the curved track on the first circular track 4, so that the angle between the vehicle entering the first circular track 4 from the main site 1 and entering the second circular track 5 from the first circular track 4 is smaller, thereby improving driving safety.

[0036] like Figure 1 As shown in this embodiment, multiple sets of complex road surface test sections 11 are arranged in both the first circular track 4 and the second circular track 5. The complex road surface test sections 11 can be washboard roads, bumpy roads, sloping roads, cobblestone roads, pothole roads, etc., to expand the test range and improve the completeness of the test data.

[0037] The specific usage and beneficial effects of this utility model are as follows:

[0038] When in use, the test track 4, the second circular track 5, and the straight track 6 are configured as test surfaces with different performance characteristics. The straight track 6 can be used as an NVH performance road. Vehicles can undergo one performance test on the first circular track 4 and then enter the second circular track 5 through the first switching port 8 for another performance test. They can also enter the inner area of ​​the second circular track 5 through the third switching port and directly drive onto the straight track 6 for NVH performance testing. Circular driving can be performed within the inner area of ​​the second circular track 5 to switch between multiple sets of straight tracks 6 with different specifications. This eliminates the need for U-turns when switching between different test sections within the test track, eliminates weaving sections between vehicles, ensures smooth traffic flow, and prevents interference between multiple sections, effectively improving test efficiency and data reliability. Furthermore, it allows for flexible use of irregular plots, saving land and maximizing the number of test lanes within the limited space, thus maximizing overall benefits.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
