Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of performance testing, specifically relating to an automatic testing system for automobile road testing with cyclic road surface generation. Background Technology
[0002] Road testing is a crucial method for verifying vehicle performance, determining whether newly designed, manufactured, or improved vehicles meet usage requirements and are suitable for operating conditions, and identifying defects and problems during actual driving. Currently, vehicle road testing primarily relies on real-world road testing. However, real-world road testing has several drawbacks.
[0003] 1) High cost: Automotive test tracks often occupy a large area, and the construction and maintenance costs are very high. Limited space often only allows a small number of vehicles to be tested at the same time, which leads to an increase in testing costs for vehicle developers.
[0004] 2) Poor test repeatability: Real-world road tests are complex and varied, resulting in poor repeatability. The conditions for each test cannot be exactly the same, leading to significant differences in test results. This makes it difficult to satisfactorily and accurately assess the stability and consistency of vehicle performance.
[0005] 3) Long cycle: Due to uncontrollable factors such as weather and traffic, the test progress is often not guaranteed, and the extended test cycle will affect the overall development progress of the vehicle.
[0006] 4) Poor safety: Driving on off-road surfaces, mountain roads, highways, and other similar surfaces poses certain risks. Actual road conditions do not provide sufficient safety measures, threatening the safety of both the driver and the vehicle.
[0007] 5) Inability to provide multi-dimensional test data: In actual vehicle road tests, the results are often checked after driving a specific distance or time. Road data and vehicle data are often separate and lack strong correlation, failing to provide robust data support for evaluating and improving vehicle performance.
[0008] With the rapid development of the automotive industry, higher requirements have been placed on the accuracy, efficiency, and repeatability of automotive performance testing. Summary of the Invention
[0009] The purpose of this invention is to provide an automated testing system for automobile road testing that generates road surfaces cyclically, in order to solve the technical problem that existing automobile road testing methods cannot meet current needs.

[0012] This invention achieves automated and precise testing of multiple performance indicators of a vehicle, including power performance, braking performance, handling performance, and economic performance, by simulating cyclical road conditions. This provides a reliable basis for vehicle research and development, production, and quality inspection. The configurable cyclical road surface provides real-time, end-to-end road condition data for vehicle road testing, offering reference data for improving vehicle performance.

Test plan configuration includes test surface configuration and test environment configuration. The vehicle-under-test management function is used to input basic vehicle information.
[0038] The road surface circulation generation module is used to cyclically generate test roads within the test area according to the test plan. It consists of road surface components, a test circulation track, a road surface component configuration library, and a road surface component deployment and retrieval mechanism. The road surface components are modular road surface units, including a lower base structure layer and an upper feature road surface layer. The base structure layer is used to securely connect with the test circulation track using mechanical, magnetic, or other methods. The feature road surface layer simulates off-road, high-speed, mountain, and snow-covered road surfaces. The circulation track, in conjunction with multiple road surface components, forms the simulated test road surface, running at the speed specified in the test plan. The road surface component configuration library stores the road surface components and performs loading and unloading of the components according to the timing specified in the test plan. The road surface component deployment and retrieval mechanism deploys road surface components onto the track and retrieves them into the library using methods such as tracks, AGVs, magnetic levitation, and the components themselves.
[0039] The environment generation module is used to simulate natural environmental information in a laboratory setting. It includes environmental output devices such as temperature and humidity control equipment, wind power control equipment, air pressure control equipment, and solar radiation control equipment, simulating environmental conditions such as temperature, humidity, air pressure, and radiation during road testing according to the test plan. The environment generation module requires a sealed laboratory and is optional. If the road testing system is built in an open-air environment, then testing will rely on the natural environment.
[0040] The data acquisition module collects and records real-time information on the vehicle's condition, road conditions, and environment. For existing information, the module integrates, analyzes, and stores data such as road conditions, environmental conditions, vehicle fuel consumption, and engine speed.

This assists in vehicle performance analysis and provides performance improvement suggestions.
[0043] Typical workflows for road testing systems are not limited to, for example Figure 2 As shown, it includes the following steps:
[0044] 1) Enter the information of the vehicle being tested
[0045] Upon receiving a testing task, vehicle information is entered into the system. This information includes, but is not limited to, the client, vehicle model, vehicle name, dimensions, and weight.
[0046] 2) Configure the test plan
[0047] Based on the client's testing requirements and vehicle conditions, a test plan is configured, including information on road conditions, speed, environment, and safety warnings. After the information is generated, the test plan is verified and checked. Once verification is successful, the test data of the vehicle under test is input into the system according to the test plan, including data that the vehicle itself can provide and data acquired through external sensing devices. Testing begins after the preparation tasks are completed.
[0048] 3) Road surface generation cycle
[0049] Based on the configured road surface information, test road surfaces are generated cyclically according to a timeline. The road surface component library, in conjunction with the road surface component delivery mechanism, sequentially transfers road surface components to the circulating track, forming a continuous test road surface that runs at a set speed. After passing through the test area, the road surface components are returned to the road surface component library via the road surface component retrieval mechanism.
[0050] 4) Environment generation
[0051] The environment generation module constructs the laboratory environment according to the configured test plan, configuring environmental conditions such as temperature, humidity, air pressure, and radiation within the laboratory. For outdoor testing, the test is conducted according to the on-site environment.
[0052] 5) Data monitoring
[0053] During the test, road surface information, vehicle information, and environmental information are monitored in real time. The monitoring data is shared throughout the system. First, it is used by the safety processing module to make safety judgments. Second, it provides data for the report analysis module to generate test reports. Third, it provides timely feedback and correction data to the road generation and environment generation modules.
[0054] 6) Safety procedures
[0055] During testing, the safety status of vehicles and personnel is analyzed in real-time using image recognition, data analysis, and other methods. Early warnings of safety risks are issued, and alerts are sent to testing and management personnel. Emergency response to sudden hazards includes controlling road conditions, intervening in vehicle control, and activating safety protection devices.
[0056] 7) Generate report
[0057] After the test concludes or is stopped for any reason, the report analysis module generates a test report based on the test results. The generated report includes, but is not limited to, road conditions, vehicle conditions, and environmental information on the timeline, and provides test results or performance improvement suggestions based on the test results.
[0058] 8) End
[0059] Restore the system after the test is finished.
[0060] 9) Other
