Technical Field

[0001] This invention relates to the field of vehicle testing technology, specifically to a vehicle durability testing method, apparatus, system, vehicle, and storage medium. Background Technology

[0002] Vehicle durability is a crucial indicator for evaluating vehicle performance. Almost every vehicle model undergoes durability testing before leaving the factory to ensure that all components can achieve their designed optimal performance and maximum service life under specified conditions. Vehicle durability testing involves a series of real and simulated tests on various vehicle indicators and performance parameters under defined conditions, and the results are used to determine the vehicle's limits under specific conditions.

[0003] Currently, vehicle durability testing is usually conducted through manual driving.

[0004] However, conducting vehicle durability tests through manual driving not only requires a large amount of human resources, but also suffers from inconsistent test results. Summary of the Invention

[0005] One objective of this invention is to provide a vehicle durability testing method to solve the problems of wasted human resources and poor consistency of test results in the prior art when conducting vehicle durability testing; another objective is to provide an apparatus; a third objective is to provide a system; a fourth objective is to provide a vehicle; and a fifth objective is to provide a storage medium.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A vehicle durability testing method, applied to a test vehicle, the method comprising:

[0008] Obtain high-precision maps and test specification information; the high-precision map is a map corresponding to the test site.

[0009] Based on the high-precision map and the test specification information, an initial test plan corresponding to the test vehicle is generated.

[0010] Based on the initial test plan and the driving environment information corresponding to the test vehicle, control the test vehicle to conduct a durability test;

[0011] The system acquires the vehicle status information corresponding to the test vehicle and sends the initial test plan and the vehicle status information to the test site control equipment, so that the test site control equipment can control the test vehicle according to the initial test plan and / or the vehicle status information.

[0012] Based on the aforementioned technical means, the test vehicle acquires high-precision maps and test specification information corresponding to the test site. An initial test plan corresponding to the test vehicle is generated based on these information. Then, according to the initial test plan and the corresponding driving environment information, the vehicle is controlled to conduct durability tests. Furthermore, the vehicle's status information is acquired, and the initial test plan and vehicle status information are sent to the test site control equipment, allowing the equipment to control the test vehicle based on the initial test plan and / or vehicle status information. This approach fully considers the current development level of intelligent driving technology and the actual situation of vehicle reliability and durability testing. By facilitating information interaction between the test vehicle and the test site control equipment, intelligent driving technology is applied to vehicle durability testing. This fully leverages the advantages of intelligent driving technology in a closed test site, saving significant human resources while avoiding human interference introduced by manual driving in durability testing, thus ensuring the consistency and reliability of vehicle durability test results.

[0013] Furthermore, after obtaining the vehicle status information corresponding to the test vehicle and sending the initial test plan and the vehicle status information to the test site control equipment, the method further includes:

[0014] If the vehicle status information meets the preset conditions, the initial test plan will be replaced with an alternative test plan.

[0015] According to the alternative test plan, the test vehicle is controlled to undergo durability testing.

[0016] Based on the aforementioned technical means, after the test vehicle undergoes durability testing, and the vehicle status information corresponding to the test vehicle during the durability test is acquired, and the initial test plan and vehicle status information are sent to the test site control equipment, the vehicle status information can be further evaluated. If the vehicle status information meets preset conditions, the initial test plan is replaced with an alternative test plan, and the test vehicle is controlled to conduct durability testing according to the alternative test plan. Therefore, the vehicle durability testing process can be controlled in real time based on the vehicle status information during the durability testing process, improving the flexibility and reliability of vehicle durability testing.

[0017] Furthermore, after controlling the test vehicle to conduct durability testing according to the alternative test plan, the method further includes:

[0018] The system acquires the vehicle status information corresponding to the test vehicle and sends the alternative test plan and the vehicle status information to the test site control equipment, so that the test site control equipment can control the test vehicle according to the alternative test plan and / or the vehicle status information.

[0019] Based on the above technical means, when the vehicle status information meets the preset conditions, the test vehicle will also promptly feed back the alternative test plan and the corresponding vehicle status information when the test vehicle conducts durability tests according to the alternative test plan to the test site control equipment, so that the test site control equipment can know the current status of the test vehicle in a timely manner, so as to control the test vehicle in the test site more accurately.

[0020] Furthermore, the vehicle status information includes vehicle strain parameters;

[0021] The step of replacing the initial test plan with an alternative test plan when the vehicle status information meets preset conditions includes:

[0022] If the vehicle strain parameters meet the first preset strain threshold, the initial test plan will be replaced with an additional test plan.

[0023] According to the alternative test plan, control the test vehicle to conduct durability tests, including:

[0024] According to the additional test plan, the test vehicle is controlled to conduct durability tests.

[0025] Based on the above technical means, the test vehicle can replace the initial test plan with an additional test plan when the vehicle strain parameters in the vehicle status information meet the first preset strain threshold. The additional test plan controls the test vehicle to carry out durability testing. The vehicle durability testing process can be controlled in real time according to the vehicle strain parameters during the durability testing process, thereby improving the flexibility and reliability of vehicle durability testing.

[0026] Furthermore, the step of replacing the initial test plan with an alternative test plan when the vehicle status information meets preset conditions also includes:

[0027] If the vehicle strain parameters meet the second preset strain threshold, the initial test plan will be replaced with a terminated test plan.

[0028] The control of the test vehicle to conduct durability tests according to the alternative test plan includes:

[0029] According to the termination test plan, the test vehicle is controlled to terminate the test and drive out of the test site.

[0030] Based on the aforementioned technical means, when the vehicle strain parameters meet the second preset strain threshold, the initial test plan is replaced with a termination test plan. According to the termination test plan, the test vehicle is controlled to terminate the test and leave the test site. This further refines the criteria for judging vehicle strain parameters, allowing for real-time control of the vehicle durability test process based on the vehicle strain parameters during the durability test, thus improving the flexibility and operability of vehicle durability testing.

[0031] Furthermore, the initial test plan includes the initial test route and the initial test conditions;

[0032] The step of generating an initial test plan corresponding to the test vehicle based on the high-precision map and the test specification information includes:

[0033] Based on the road specifications in the test specification information, determine the initial test route corresponding to the road specifications in the high-precision map;

[0034] The initial test conditions are determined based on the operating condition information in the test specification information;

[0035] Based on the initial test route and the initial test conditions, an initial test plan corresponding to the test vehicle is generated.

[0036] Based on the aforementioned technical means, the initial test route and initial test conditions are first determined according to the road specifications and working conditions in the test specification information. Then, the initial test plan corresponding to the test vehicle is further generated based on the initial test route and initial test conditions, ensuring the executability of the initial test plan.

[0037] A vehicle durability testing method, applied to test site control equipment, the method comprising:

[0038] The system receives an initial test plan and vehicle status information sent by a test vehicle. The initial test plan is a test plan generated by the test vehicle based on a high-precision map and test specification information, which are acquired by the test vehicle. The high-precision map is a map corresponding to the test site. The vehicle status information is the status information corresponding to the test vehicle obtained after the test vehicle performs durability testing based on the initial test plan and the driving environment information corresponding to the test vehicle.

[0039] The test vehicle is controlled according to the initial test plan and / or the vehicle status information.

[0040] Based on the aforementioned technical means, after receiving the initial test plan and vehicle status information sent by the test vehicle, the test site control equipment controls the test vehicle according to the initial test plan and / or vehicle status information. While the test vehicle is performing durability testing, the test site control also performs overall scheduling control of all test vehicles within the test site based on the initial test plan and / or vehicle status information sent by the test vehicle. This ensures the smooth progress of the durability testing process for all test vehicles within the test site, saving manpower, ensuring the consistency and reliability of vehicle durability test results, and improving the efficiency of vehicle durability testing.

[0041] Furthermore, the test vehicle includes a first test vehicle and at least one second test vehicle;

[0042] The step of controlling the test vehicle according to the initial test plan and / or the vehicle status information includes:

[0043] If the first vehicle status information corresponding to the first test vehicle includes alarm information, then the alarm information is obtained.

[0044] When the alarm information meets the test termination conditions, a first control command is sent to the first test vehicle, the first control command being used to instruct the first test vehicle to suspend the test.

[0045] Based on the high-precision map and the first vehicle status information, determine the first position of the first test vehicle;

[0046] Based on the first location, a second control command is sent to the second test vehicle; the second control command is used to instruct the second test vehicle to detour around the first location.

[0047] Based on the aforementioned technical means, in a scenario where multiple test vehicles are present in the test site, when the first test vehicle malfunctions, the test site control equipment can, based on the first vehicle status information corresponding to the first test vehicle, control the first test vehicle to suspend testing via a first control command. Simultaneously, it can control a second test vehicle outside the first test vehicle in the test site to detour around the first test vehicle at the first location via a second control command. This avoids a collision between the second test vehicle and the first test vehicle at the first location in the test site, thereby improving the safety of vehicle durability testing within the test site and ensuring that all test vehicles in the test site can successfully conduct vehicle durability testing.

[0049] The acquisition module is used to acquire high-precision maps and test specification information; the high-precision map is a map corresponding to the test site.

[0050] The test plan generation module is used to generate an initial test plan corresponding to the test vehicle based on the high-precision map and the test specification information.

[0051] The first control module is used to control the test vehicle to perform durability testing according to the initial test plan and the driving environment information corresponding to the test vehicle.

[0052] The sending module is used to acquire the vehicle status information corresponding to the test vehicle, and send the initial test plan and the vehicle status information to the test site control equipment, so that the test site control equipment can control the test vehicle according to the initial test plan and / or the vehicle status information.

[0053] Based on the aforementioned technical means, the test vehicle acquires high-precision maps and test specification information corresponding to the test site. An initial test plan corresponding to the test vehicle is generated based on these information. Then, according to the initial test plan and the corresponding driving environment information, the vehicle is controlled to conduct durability tests. Furthermore, the vehicle's status information is acquired, and the initial test plan and vehicle status information are sent to the test site control equipment, allowing the equipment to control the test vehicle based on the initial test plan and / or vehicle status information. This approach fully considers the current development level of intelligent driving technology and the actual situation of vehicle reliability and durability testing. By facilitating information interaction between the test vehicle and the test site control equipment, intelligent driving technology is applied to vehicle durability testing. This fully leverages the advantages of intelligent driving technology in a closed test site, saving significant human resources while avoiding human interference introduced by manual driving in durability testing, thus ensuring the consistency and reliability of vehicle durability test results.

[0054] A vehicle durability testing device, applied to test site control equipment, the device comprising:

[0055] The receiving module is used to receive the initial test plan and vehicle status information sent by the test vehicle; the initial test plan is a test plan corresponding to the test vehicle generated by the test vehicle based on a high-precision map and test specification information, wherein the high-precision map and test specification information are acquired by the test vehicle; the high-precision map is a map corresponding to the test site; the vehicle status information is the status information corresponding to the test vehicle acquired by the test vehicle after controlling the test vehicle to conduct durability testing according to the initial test plan and the driving environment information corresponding to the test vehicle.

[0056] The second control module is used to control the test vehicle according to the initial test plan and / or the vehicle status information.

Detailed Implementation

[0076] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0077] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0078] This invention provides a vehicle durability testing method, which can be applied to test vehicles, as described in Figure 1. Figure 1This is a flowchart of the steps of a vehicle durability testing method according to the present invention, as follows: Figure 1 As shown, the vehicle durability testing method may include the following steps:

[0079] Step 110: Obtain high-precision map and test specification information.

[0080] The high-precision map is the map corresponding to the test site. High-precision maps, compared to ordinary maps, have higher requirements in terms of detail and richness. Specifically, ordinary maps have meter-level accuracy, while high-precision maps can reach centimeter-level accuracy. High-precision maps are mainly used in the field of intelligent driving technology, and their higher detail and richness provide a safe and reliable guarantee for intelligent driving. Due to the continuous iteration and upgrading of intelligent driving technology, as well as the complexity of current open roads and the special nature of legal regulations, it will still take a long time for intelligent driving technology to achieve fully autonomous driving. However, the vehicle durability testing method provided in this invention applies intelligent driving technology to conduct vehicle durability tests in a closed test site, fully leveraging the advantages of intelligent driving technology and solving the problems of wasted human resources and poor consistency of test results that exist when conducting vehicle durability tests through manual driving in related technologies.

[0081] It should be noted that the high-precision map can include information such as the name, location, type, width, slope, and curvature of the lanes within the test site. Furthermore, the high-precision map can also include ancillary facilities and their structures related to the lanes within the test site, such as lane guardrails, road markings, traffic signs, and safety features, as well as restrictions such as height and speed limits. The high-precision maps for different test sites can be the same or different.

[0082] In this embodiment of the invention, the test vehicle in the test site can communicate with the test site control equipment via a wireless connection. The test vehicle can obtain a high-precision map of the test site from the test site control equipment via the wireless connection. Of course, vehicle test personnel can also download the high-precision map of the test site to the test vehicle before conducting durability tests; this embodiment of the invention does not specifically limit this.

[0083] The test specification information refers to the driving conditions and requirements for the test vehicle specified by the test vehicle user. It is used to test the fatigue strength and designed service life of various systems and components of the vehicle. The test specification information may include, but is not limited to: test road type (e.g., reinforced rough road, highway, general road, etc.), test road combination, number of test cycles, test sequence arrangement, test speed, test gear, and test mileage. In this embodiment of the invention, the test specification information can be input into the test vehicle by the tester, or it can be input into the test site control equipment in advance. Once a communication connection is established between the test site control equipment and the test vehicle corresponding to the test specification information, the test site control equipment sends the test specification information to the test vehicle. The test specification information input by the tester into the test vehicle or test site control equipment can be input in the following three aspects: 1) Test classification and cycle allocation of test road combinations; 2) Definition and response to deviations during test execution; 3) Operational details for each test cycle. It should be noted that the above tests may include vehicle durability testing.

[0084] Step 120: Generate an initial test plan corresponding to the test vehicle based on the high-precision map and the test specification information.

[0085] The initial test plan is a test plan generated by the test vehicle based on the high-precision map and test specification information obtained in step 110.

[0086] The test vehicle generates an initial test plan based on the high-precision map and test specification information obtained in step 110. This plan may specifically include:

[0087] Step A121: Match the corresponding test road type in the high-precision map according to the test road type in the test specification information;

[0088] Step A122: According to the test road combination in the test specification information, combine the roads in the high-precision map that correspond to the test road type to obtain the combined test road;

[0089] Step A123: Determine the number of test cycles for the combined test road cyclic test according to the test mileage specified in the test specification information;

[0090] Step A124: Determine the corresponding gear and speed of the test vehicle during the durability test according to the test speed and test gear specified in the test specification information.

[0091] It should be noted that different road types may correspond to different test speeds or test gears, or they may correspond to the same test speed or test gear; different cyclic tests may also correspond to different test speeds or test gears, or they may correspond to the same test speed or test gear. This embodiment of the invention does not impose specific limitations in this regard.

[0092] Optionally, the initial test plan includes an initial test route and initial test conditions; step 120, generating the initial test plan corresponding to the test vehicle based on the high-precision map and the test specification information, may include the following steps:

[0093] Step B121: Based on the road specifications in the test specification information, determine the initial test route corresponding to the road specifications in the high-precision map.

[0094] Step B122: Determine the initial test conditions based on the working condition information in the test specification information.

[0095] Step B123: Generate an initial test plan corresponding to the test vehicle based on the initial test route and the initial test conditions.

[0096] In this embodiment of the invention, the initial test plan generated by the test vehicle based on the high-precision map and test specification information may include an initial test route and initial test conditions. The initial test route is the route the test vehicle must travel on within the test site when conducting tests according to the initial test plan; the initial test conditions are the specific operating conditions of the test vehicle while traveling along the initial test route in the initial test plan, such as the vehicle speed and gear position. Therefore, when generating the initial test plan based on the high-precision map and test specification information, the initial test route corresponding to the road specifications can be determined first in the high-precision map according to the road specifications in the test specification information; then, the initial test conditions can be determined according to the operating condition information in the test specification information; finally, the initial test plan corresponding to the test vehicle can be generated based on the initial test route and initial test conditions.

[0097] It should be noted that the test specification information may include road specifications, which may include information such as the type of test roads, test road combinations, test mileage, number of test cycles, and test sequence arrangement required for the vehicle to undergo durability testing. Specifically, the test vehicle determines its initial test route on the high-precision map based on the road specifications in the test specification information: the test vehicle determines the initial test route it needs to travel on the test site based on the test road type, test road combinations, test mileage, number of test cycles, and test sequence arrangement information. Furthermore, the test specification information may also include test condition information, which may include information such as the test speed and test gear during durability testing. Specifically, the test vehicle determines its initial test conditions based on the test condition information in the test specification information: the test vehicle determines the initial test conditions it needs to travel on the test site based on the test speed and test gear information.

[0098] The initial test plan generated for the test vehicle based on the initial test route and initial test conditions can be specifically as follows: The test vehicle associates the initial test route with the initial test conditions to generate an initial test plan that the test vehicle can execute. For example, if the initial test route includes a general road, a concrete road, and a high-speed ring road, then the initial test plan generated for the test vehicle based on the initial test route and initial test conditions can be as follows: associate the general road with the first test condition corresponding to the general road (e.g., vehicle speed 90 km / h, gear 2), associate the concrete road with the second test condition corresponding to the concrete road (e.g., vehicle speed 80 km / h, gear 1), and associate the high-speed ring road with the third test condition corresponding to the high-speed ring road (e.g., vehicle speed 120 km / h, gear 3).

[0099] Step 130: Based on the initial test plan and the driving environment information corresponding to the test vehicle, control the test vehicle to conduct a durability test.

[0100] Among them, the driving environment information is the environmental information corresponding to the test vehicle, such as the current speed and position of the test vehicle, as well as the obstacles in front of the lane in which the test vehicle is located.

[0101] In this embodiment of the invention, the test vehicle may include an environmental detection unit, which includes, but is not limited to, radar, camera, GPS (Global Positioning System), speed sensor, etc.

[0102] Before performing step 130, the test vehicle can first obtain driving environment information through the environmental detector, and then perform the operation corresponding to step 130.

[0103] Specifically, based on the initial test plan and the driving environment information corresponding to the test vehicle, the test vehicle is controlled to conduct durability tests, including: controlling the test vehicle to drive in the test site according to the initial test route and initial test conditions in the initial test plan, and controlling the test vehicle to drive safely in the test site according to the driving environment information, such as turning, avoiding obstacles, etc.

[0104] Step 140: Obtain the vehicle status information corresponding to the test vehicle, and send the initial test plan and the vehicle status information to the test site control equipment so that the test site control equipment can control the test vehicle according to the initial test plan and / or the vehicle status information.

[0105] In this embodiment of the invention, after controlling the test vehicle to perform durability testing in step 130, the test vehicle can obtain the vehicle status information corresponding to the test vehicle in real time during the durability testing process and send the vehicle status information to the test site control equipment. Of course, it can also obtain the vehicle status information corresponding to the test vehicle according to a preset cycle and send the vehicle status information to the test site control equipment.

[0106] Furthermore, the timing of sending the initial test plan to the test site control equipment can be the same as or different from sending the measurement status information. For example, the initial test plan corresponding to the test vehicle can be sent at the same time as the test vehicle sends its vehicle status information to the test site control equipment, or it can be sent to the test site control equipment after the initial test plan is generated in step 130, and if the test plan changes, the changed test plan can be sent to the test site control equipment again. For example, under certain conditions, after replacing the initial test plan with a different test plan, the replaced test plan can be sent to the test site control equipment again, so that the test site control equipment can control the test vehicle according to the latest test plan and / or vehicle status information.

[0107] In this embodiment of the invention, the test vehicle may include an intelligent driving control component, which may include, but is not limited to, an on-board host, an environmental detection unit, a drive execution unit, and a test detection unit. The test vehicle can implement the vehicle durability testing method described in steps 110 to 140 through the on-board host.

[0108] Specifically, the test vehicle can obtain high-precision map and test specification information through the on-board host, and generate an initial test plan corresponding to the test vehicle based on the high-precision map and test specification information; then, the on-board host obtains the driving environment information corresponding to the test vehicle through the environmental detection unit, and then controls the drive execution unit to control the test vehicle to conduct durability tests based on the initial test plan and the driving environment information corresponding to the test vehicle; finally, the on-board host obtains the vehicle status information corresponding to the test vehicle through the test detection unit, and sends the initial test plan and the vehicle status information to the test site control equipment.

[0109] The vehicle-mounted host can establish a wireless network connection with the test site control equipment after entering the test site, and disconnect from the wireless network connection with the test site control equipment after leaving the test site. The vehicle-mounted host can exchange information with the test site control equipment through the wireless network. For example, the vehicle-mounted host can obtain high-precision map or test specification information from the test site control equipment through the wireless network, send vehicle status information to the test site control equipment through the network cable, and receive control commands sent by the test site control equipment through the wireless network.

[0110] The onboard host interacts with the environmental detection unit, drive execution unit, and test and detection unit via a CAN (Controller Area Network). For example, the onboard host obtains driving environment information from the environmental detection unit through the CAN network, controls the drive execution through the CAN network, and obtains vehicle status information from the test and detection unit through the CAN network.

[0111] In this embodiment of the invention, the vehicle-mounted host obtains vehicle status information through the test and detection unit, specifically including: receiving alarm information sent by the test and detection unit, and controlling the drive execution unit to stop, shut down, decelerate, or leave the test site. Furthermore, the vehicle-mounted host is also used to, after obtaining the vehicle status information corresponding to the test vehicle, determine whether the test process is normal based on the vehicle status information and preset conditions, and adjust the test process if the preset conditions are met, for example, by extending the current test phase or test mileage, or suspending the durability test.

[0112] It should be noted that the drive execution unit may include, but is not limited to, electric power steering (EPS), engine management system (EMS), and electronic stability control system (ESC). The testing and detection unit includes multiple functional devices for detecting vehicle status information such as wear and fatigue conditions of various systems and components. These functional devices may include sensors, such as strain gauges. Specifically, multiple strain gauges can be installed at key structural components of the test vehicle, such as the chassis lower control arm, subframe, steering knuckle, powertrain support, and lower body suspension mounting points.

[0113] Reference Figure 2 , Figure 2 This is a schematic diagram of the structure of a test vehicle according to the present invention. Figure 2 As shown, the test vehicle includes: an intelligent driving control component, which includes an on-board host 11, GPS 12, camera 13, radar 14, engine management system 15, electronic stability control system 16, electric power steering system 17, and test and detection unit 18.

[0114] Before conducting vehicle durability tests after the test vehicle enters the test site, an on-board unit 11 needs to be installed in a suitable location inside the vehicle. Cameras 13 and radars 14 are also installed at suitable locations at the front and rear of the vehicle. A GPS 12 is installed on the roof of the vehicle and establishes a CAN network connection with the on-board unit 11. The on-board unit 11 can obtain driving environment information collected by the cameras 13 and radars 14, and the GPS 12 installed on the roof of the vehicle via the CAN network. Furthermore, the on-board unit 11 also needs to establish a wireless network connection with the test site control equipment to enable information exchange with the test site control equipment.

[0115] Furthermore, a test and detection unit 18 is installed and a CAN network connection is established with the vehicle host 11. The vehicle host 11 can obtain the vehicle status information detected by the test and detection unit 18 through the CAN network.

[0116] Furthermore, the vehicle host 11 establishes CAN network connections with the engine management system 15, the electronic stability control system 16, and the electric power steering system 17, respectively. The vehicle host 11 can send control commands to the engine management system 15, the electronic stability control system 16, and the electric power steering system 17 through the CAN network to control the engine management system 15, the electronic stability control system 16, and the electric power steering system 17.

[0117] Optionally, after obtaining the vehicle status information corresponding to the test vehicle in step 140 and sending the initial test plan and the vehicle status information to the test site control equipment, the following steps may also be included:

[0118] Step 150: If the vehicle status information meets the preset conditions, replace the initial test plan with an alternative test plan.

[0119] Step 160: Control the test vehicle to conduct a durability test according to the alternative test plan.

[0120] In this embodiment of the invention, the preset conditions can be conditions pre-set based on the test mileage and the wear condition of the test vehicle parts. For example, setting the wear of the test vehicle parts to be less than or equal to 30% when the test mileage is 20,000 kilometers as a preset condition, and when the test vehicle determines, based on the vehicle status information, that the wear of the test vehicle parts is less than or equal to 30%, the initial test plan can be replaced with an alternative test plan. The preset conditions can also be conditions pre-set based on the test mileage and the strain state of the test vehicle parts. For example, setting the strain of the test vehicle parts to be greater than 55% when the test mileage is 80,000 kilometers as a preset condition, and when the test vehicle determines, based on the vehicle status information, that the strain of the parts is greater than 55% when the test mileage is 80,000 kilometers, the initial test plan can be replaced with an alternative test plan.

[0121] The alternative test plan is a test plan generated based on preset conditions. This alternative test plan differs from the initial test plan. For example, if the preset conditions are a test mileage of 20,000 kilometers and a wear rate of less than or equal to 30% for the test vehicle parts, the corresponding alternative test plan could be to extend the test mileage, change the test road type, or adjust the test speed compared to the initial test plan. As another example, if the preset conditions are a test mileage of 80,000 kilometers and a wear rate of more than 55% for the test vehicle parts, the corresponding alternative test plan could be to shorten the test mileage, change the test road type, adjust the test speed, or stop the test compared to the initial test plan.

[0122] In this embodiment of the invention, after the initial test plan is replaced with an alternative test plan in step 150, the test vehicle will be controlled to perform durability testing according to the alternative test plan.

[0123] Optionally, after controlling the test vehicle to conduct durability testing according to the alternative test plan as described in step 160, the following steps may also be included:

[0124] Step 170: Obtain the vehicle status information corresponding to the test vehicle, and send the alternative test plan and the vehicle status information to the test site control equipment so that the test site control equipment can control the test vehicle according to the alternative test plan and / or the vehicle status information.

[0125] In this embodiment of the invention, after the test vehicle replaces the initial test plan with an alternative test plan and controls the test vehicle to conduct durability tests according to the alternative test plan, it needs to send the alternative test plan currently being executed by the test vehicle to the test site control equipment, so that the test site control equipment can know the current status of the test vehicle in a timely manner, so as to control the test vehicle in the test site more accurately.

[0126] Optionally, the vehicle status information may include vehicle strain parameters. Step 150, where the vehicle status information meets preset conditions, involves replacing the initial test plan with an alternative test plan, which may include the following steps:

[0127] Step A151: If the vehicle strain parameters meet the first preset strain threshold, replace the initial test plan with an additional test plan.

[0128] Optionally, step 160, which involves controlling the test vehicle to perform durability testing according to the alternative test plan, may include the following steps:

[0129] Step A161: Control the test vehicle to conduct a durability test according to the additional test plan.

[0130] It should be noted that vehicle status information may include vehicle strain parameters, which are the strain parameters of the test vehicle's components. When it is necessary to detect the strain state of multiple components corresponding to multiple parts of the test vehicle, strain gauges can be installed on each component, and the strain parameters of the corresponding component can be obtained through the strain sensors in the strain gauges. Then, the average value of the strain parameters of each component is determined as the vehicle strain parameter.

[0131] In this embodiment of the invention, the test vehicle can control the ongoing durability test process based on the vehicle strain parameters. Specifically, when the vehicle strain parameters meet a first preset strain threshold, the initial test plan can be replaced with an additional test plan.

[0132] It should be noted that the preset conditions may include a first preset strain threshold, and the alternative test conditions may include additional test plans. For example, the first preset strain threshold may be: when the vehicle strain parameter is less than or equal to 35% at a test mileage of 50,000 kilometers, the additional test plan corresponding to the first preset strain threshold may be to extend the test mileage to 150,000 kilometers according to the same test conditions and test road type as in the initial test plan. Alternatively, the additional test plan corresponding to the first preset strain threshold may also be to change the test road type in the initial test plan from a general highway to a concrete road and extend the test mileage to 130,000 kilometers.

[0133] In this embodiment of the invention, after the initial test plan is replaced with an additional test plan in step A151, the test vehicle will continue to perform durability testing according to the additional test plan.

[0134] Optionally, step 150, which involves replacing the initial test plan with an alternative test plan when the vehicle status information meets preset conditions, may further include the following steps:

[0135] Step B151: If the vehicle strain parameters meet the second preset strain threshold, replace the initial test plan with the termination test plan.

[0136] Optionally, step 160, which involves controlling the test vehicle to conduct a durability test according to the alternative test plan, may further include the following steps:

[0137] Step B161: According to the termination test plan, control the test vehicle to terminate the test and drive out of the test site.

[0138] In this embodiment of the invention, the test vehicle can control the ongoing durability test process based on the vehicle strain parameters. Specifically, if the vehicle strain parameters meet a second preset strain threshold, the initial test plan can be replaced with a terminated test plan.

[0139] It should be noted that the preset conditions may also include a second preset strain threshold, and alternative test conditions may include terminating the test plan. For example, if the second preset strain threshold is: when the test mileage is 80,000 kilometers, the strain of the test vehicle components is greater than 55%, the termination test plan corresponding to the second preset strain threshold may be to control the test vehicle to decelerate and drive out of the test site.

[0140] In this embodiment of the invention, after the initial test plan is replaced with the termination test plan in step B151, the test vehicle will control the test vehicle to terminate the durability test according to the termination test plan.

[0141] Reference Figure 3 , Figure 3 This is a schematic diagram of the control logic for a test vehicle according to the present invention. Figure 3 As shown, the on-board host 11 of the test vehicle acquires driving environment information through the environmental detection unit 19, which includes GPS 12, camera 13, and radar 14. The on-board host 11 sends control commands to the drive control unit 20 according to the initial test plan or alternative test plan. The drive control unit 20 controls the electric power steering system 17, the electronic stability control system 16, and the engine management system 15 respectively, thereby enabling the test vehicle to conduct vehicle durability tests according to the initial test plan or alternative test plan. In addition, the on-board host 11 also acquires vehicle strain parameters through the test detection unit 20, which includes a stress plate 21. The test detection unit 20 acquires vehicle strain parameters through the stress sensor in the stress plate 21.

[0142] This invention provides another vehicle durability testing method, which can be applied to test site control equipment, as shown in Figure 4. Figure 4 This is a flowchart of another vehicle durability testing method according to the present invention, as follows: Figure 4 As shown, the vehicle durability testing method may include the following steps:

[0143] Step 210: Receive the initial test plan and vehicle status information sent by the test vehicle.

[0144] The initial test plan is a test plan generated by the test vehicle based on a high-precision map and test specification information, which is acquired by the test vehicle. The high-precision map is a map corresponding to the test site. The vehicle status information is the status information corresponding to the test vehicle obtained after the test vehicle conducts a durability test based on the initial test plan and the driving environment information corresponding to the test vehicle.

[0145] It should be noted that the test site control equipment is the control equipment corresponding to the test site, used to control all test vehicles within the test site. For example, the test site control equipment can control some or all vehicles within the test site to terminate or begin testing. In this embodiment of the invention, the control commands sent by the test site control equipment to the on-board host of the test vehicle have a higher priority than the control commands sent by the on-board host to the drive control unit of the test vehicle. That is, when the control commands of the test site control equipment and the control commands of the on-board host are inconsistent, the control commands of the test site control equipment are executed by default.

[0146] In this embodiment of the invention, the test site control device receives the initial test plan and vehicle status information sent by the test vehicle. Of course, if the initial test plan corresponding to the test vehicle is replaced with an alternative test plan, the test site control device will also receive the alternative test plan and vehicle status information sent by the test vehicle. It should be noted that the test plan corresponding to the test vehicle can be sent to the test site control device when the test plan is replaced or a new test plan is generated; the test site control device can periodically receive the vehicle status information.

[0147] Reference Figure 5 , Figure 5 This is a schematic diagram of a test site according to the present invention. Figure 5 As shown, the test site includes multiple test vehicles 1, test site control equipment 2, and different types of test lanes.

[0148] Among them, different test vehicles 1 drive in different test lanes according to their respective test plans to carry out durability tests; the test site control equipment 2 can receive the initial test plan, vehicle status information and alternative test plans sent by different test vehicles, and then schedule and control all test vehicles in the test site according to at least one of the initial test plan, alternative test plans and vehicle status information.

[0149] In this embodiment of the invention, the test site control device may include, but is not limited to, a power supply, a computing processing unit, and a wireless transmission unit. The test site control device can obtain relevant information about all test vehicles within the test site via a wireless network and establish long-term wireless network connections with all test vehicles within the test site. Furthermore, the test site control device can also send high-precision maps of the test site or test specification information corresponding to different test vehicles to different test vehicles. The test site control device can also send control commands to test vehicles based on other management requirements, weather conditions, and temporary situations, and overall schedule the operation of test vehicles within the test site.

[0150] Specifically, the test site control equipment can establish a wireless network connection with the on-board host of the test vehicle, receive the initial test plan and vehicle status information sent by the on-board host of the test vehicle, send high-precision maps or test specification information to the on-board host, and send control commands to the on-board host.

[0151] Step 220: Control the test vehicle according to the initial test plan and / or the vehicle status information.

[0152] In this embodiment of the invention, after receiving the initial test plan and vehicle status information sent by the test vehicle, the test site control equipment can control the test vehicle according to the initial test plan, the vehicle status information, or both. Furthermore, the control of the test vehicle by the test site control equipment is not limited to the initial test plan and vehicle status information; it can also be based on high-precision maps, alternative test plans, other management requirements, weather conditions, and temporary situations. This embodiment of the invention does not specifically limit the scope of control in these areas.

[0153] Optionally, the test vehicle includes a first test vehicle and at least one second test vehicle. Step 220, controlling the test vehicle according to the initial test plan and / or the vehicle status information, may include the following steps:

[0154] Step 221: If the first vehicle status information corresponding to the first test vehicle includes alarm information, obtain the alarm information.

[0155] Step 222: When the alarm information meets the test termination conditions, send a first control command to the first test vehicle. The first control command is used to instruct the first test vehicle to suspend the test.

[0156] Step 223: Determine the first position of the first test vehicle based on the high-precision map and the first vehicle status information.

[0157] Step 224: Based on the first position, send a second control command to the second test vehicle; the second control command is used to instruct the second test vehicle to detour around the first position.

[0158] In this embodiment of the invention, a scenario is described where multiple test vehicles are simultaneously undergoing durability testing at a test site, and any one of the test vehicles generates an alarm message. Specifically, the first test vehicle is any one of the multiple test vehicles simultaneously undergoing durability testing at the test site, and the second test vehicle is some or all of the multiple test vehicles simultaneously undergoing durability testing at the test site, excluding the first test vehicle.

[0159] If the vehicle status information of the first test vehicle received by the test site control equipment includes alarm information, the test site control equipment will determine whether the alarm information meets the test termination conditions based on the alarm information. If it does, the equipment will control the first test vehicle to suspend the test through the first control command and control the second test vehicle to detour around the first position where the first test vehicle is located through the second control command.

[0160] It should be noted that test termination conditions may include, but are not limited to: vehicle component failure requiring replacement before testing, and failure of the durability test. Specifically, if the test termination condition is a vehicle component failure requiring replacement before testing, the first control command can be used to suspend the test on the first test vehicle while simultaneously notifying the test personnel to replace the faulty component in the first test vehicle. If the test termination condition is a failure of the durability test, the first control command can be used to suspend the test on the first test vehicle and drive it out of the test area.

[0161] By controlling the second test vehicle to detour around the first test vehicle at the first location using the second control command, collisions and rear-end accidents between the second test vehicle and other test vehicles in the test site can be avoided, ensuring the normal testing of other test vehicles in the test site.

[0162] For example, if a test vehicle experiences a power failure and cannot move, after the test site control equipment receives vehicle status information including alarm information from the test vehicle, the test site control equipment identifies the test vehicle's location as being within the high-speed loop area. The test site control equipment will then send a control command instructing all test vehicles within the current high-speed loop area to reduce their speed. If the faulty vehicle stops in the middle of the area, the test site control equipment will send a control command instructing all test vehicles within the current high-speed loop area to temporarily suspend testing until the test site provides assistance. After the assistance is provided, the test site control equipment will send another control command instructing all test vehicles within the high-speed loop area to resume testing, and then all test vehicles within the high-speed loop area will restart testing.

[0163] Furthermore, in this embodiment of the invention, if the actual speed of the test vehicle deviates from the test speed specified in the initial test plan or alternative test plan, the degree of deviation can be used to determine whether the durability test should continue. For example, if the test speed corresponding to the test vehicle is below 100 km / h, and the actual speed of the test vehicle deviates from the test speed by less than 5 km / h, the durability test can continue; otherwise, the test is suspended. If the test speed corresponding to the test vehicle is above 100 km / h, and the actual speed of the test vehicle deviates from the test speed by less than 8 km / h, the durability test can continue; otherwise, the test is suspended.

[0164] Optionally, when a single test road within the test site is forced to close due to maintenance, repair, malfunction, or other factors, the test site control equipment can send a third control command to all test vehicles within the test site, instructing all test vehicles to detour around the closed test road. When the test road reopens, the equipment can send a fourth control command sequentially to all test vehicles included in the initial test plan for that test road, instructing the test vehicles to conduct durability tests on that test road in sequence, thereby completing the durability tests for that test road in the initial test plan.

[0165] Optionally, the test site control equipment can also, based on the current weather conditions, instruct all test vehicles in the test site to suspend testing and leave the test site via a fifth control command under adverse weather conditions, and mark the durability test progress of each test vehicle. For example, the current durability test completion rate of the first test vehicle is 10%. After the weather conditions improve, the sixth control command can instruct all test vehicles to continue the durability test from the previous suspension progress. For example, when the durability test completion rate of the first test vehicle was 10% at the last suspension, after the weather conditions improve, the test vehicle will continue the durability test from the 10% point.

[0166] For example, the initial test plan for a Class A sedan is as follows:

[0167] Phase 1: The test is named Structural Durability Test, with 200 test cycles and a single cycle distance of 30km (length unit: kilometers). The test road types are reinforced bad roads and general highways.

[0168] Phase Two: The test is called the Power Condition Test, which consists of 200 test cycles, with a single cycle distance of 70km. The test road types are general highways, expressway ring roads, and ramps.

[0169] Phase 3: The test is named High-Speed ​​Continuous Test, with 76 test cycles, each cycle covering 150km, and the test road type being a high-speed ring road.

[0170] Specifically, the operational details of the durability tests conducted on the test vehicles according to this initial test plan are as follows:

[0171] Phase 1: At the entrance to the reinforced rough road, the vehicle is tested in 1st gear at a speed of 3-4 km / h. At the entrance to the vibrating road, the vehicle is tested in 2nd gear, accelerating to 35 km / h and passing through steadily. Upon passing the vibrating road entrance, the vehicle is then tested in 3rd gear. When entering the regular road, the vehicle enters at a speed of 50 km / h, accelerates to 80 km / h at full throttle for 2 seconds, and then brakes to a stop using a 0.3G deceleration.

[0172] Phase Two: Upon entering the high-speed ring road, accelerate to 110 km / h at full throttle and maintain that speed. Shift to 3rd gear, keeping the shift points below 6000 rpm (Revolutions Per Minute), completing a distance of 395 meters. Then shift to 4th gear and accelerate to 130 km / h at full throttle, completing a distance of 720 meters.

[0173] Reference Figure 6 , Figure 6 This is a flowchart of another vehicle durability testing method according to the present invention, as follows: Figure 6 As shown, the method may include the following steps:

[0174] Step 601: Test vehicle enters the site.

[0175] Specifically, the test vehicles entered the test site.

[0176] Step 602: Install the vehicle-mounted host.

[0177] Specifically, after the test vehicle enters the test site, the on-board host can be installed in the test vehicle first.

[0178] Step 603: Install the test and detection unit.

[0179] Specifically, after installing the vehicle-mounted host, a test and detection unit can be installed to acquire vehicle status information during durability testing and send the information to the vehicle-mounted host. The test and detection unit may include stress gauges, each containing a stress sensor, to acquire real-time vehicle strain parameters during durability testing and transmit these parameters to the vehicle-mounted host via a CAN network.

[0180] Step 604: Determine whether the environmental detection unit meets the standards.

[0181] Specifically, after installing the on-board host and test detection unit in the test vehicle, an environmental detection unit also needs to be installed to acquire information about the current driving environment of the test vehicle. Determining whether the environmental detection unit meets the requirements mainly involves assessing whether the unit can acquire driving environment information and whether the acquired information meets the requirements.

[0182] If the environmental detection unit is deemed to meet the standard, then proceed to step 606; if the environmental detection unit is deemed not to meet the standard, then proceed to step 605.

[0183] Step 605: Install the environmental detection unit.

[0184] Specifically, if it is determined in step 604 that the environmental detection unit does not meet the standard, then step 605 is executed to install the environmental detection unit. The installation of the environmental detection unit may include the installation of a camera, radar, GPS, etc., and the specific installation can be carried out according to actual usage requirements. This embodiment of the invention does not make specific limitations in this regard.

[0185] Step 606: Establish communication between the vehicle-mounted host and the environmental control unit, drive control unit, and test and detection unit.

[0186] Specifically, if the environmental detection unit meets the standard in step 604, then step 606 is executed to establish communication between the vehicle-mounted host and the environmental control unit, the drive control unit, and the test and detection unit. This communication establishment between the vehicle-mounted host and the environmental control unit, drive control unit, and test and detection unit can involve establishing CAN network communication connections between the vehicle-mounted host and each of these units.

[0187] Step 607: Establish communication with the test site control equipment.

[0188] Specifically, after the vehicle-mounted host establishes communication with the environmental control unit, drive control unit, and test and detection unit, the vehicle-mounted host also needs to establish a communication connection with the test site control equipment. Specifically, the vehicle-mounted host can establish a wireless network connection with the test site control equipment.

[0189] Step 608: Obtain a high-precision map.

[0190] Specifically, the vehicle-mounted host can acquire high-precision maps in ways including, but not limited to: the vehicle-mounted host connecting via a wireless network to receive high-precision maps sent by the test site control equipment; or the test personnel can directly input the high-precision map into the vehicle-mounted host. The high-precision map is the map corresponding to the test site.

[0191] Step 609: Obtain test specification information.

[0192] Specifically, the ways in which the vehicle-mounted host obtains high-precision maps may include, but are not limited to: the vehicle-mounted host connecting via a wireless network to receive test specification information sent by the test site control equipment; or the test personnel directly uploading test specification information to the vehicle-mounted host.

[0193] Step 610: Generate the initial test plan.

[0194] Specifically, the on-board unit can generate an initial test plan corresponding to the test vehicle based on the high-precision map obtained in step 608 and the test specification information obtained in step 609, so that step 611 can conduct vehicle durability testing based on the initial test plan.

[0195] Step 611: Conduct vehicle durability testing.

[0196] Specifically, the on-board host can control the test vehicle to conduct durability tests according to the initial test plan generated in step 610.

[0197] In this embodiment of the invention, the test vehicle acquires high-precision maps and test specification information corresponding to the test site, and generates an initial test plan corresponding to the test vehicle based on the high-precision maps and test specification information. Then, based on the initial test plan and the driving environment information corresponding to the test vehicle, the vehicle is controlled to conduct durability tests. Additionally, the vehicle status information corresponding to the test vehicle is acquired, and the initial test plan and vehicle status information are sent to the test site control equipment, so that the test site control equipment can control the test vehicle according to the initial test plan and / or vehicle status information. This fully considers the current development level of intelligent driving technology and the actual situation of vehicle reliability and durability testing. Through information interaction between the test vehicle and the test site control equipment in the test site, intelligent driving technology is applied to vehicle durability testing. This fully leverages the advantages of intelligent driving technology in a closed test site, saving a significant amount of human resources while avoiding human interference introduced by manual driving in durability testing, ensuring the consistency and reliability of vehicle durability test results.

[0198] This invention provides a vehicle durability testing system, which may include: a test vehicle and test site control equipment;

[0199] The test vehicle is used to: acquire high-precision maps and test specification information; generate an initial test plan corresponding to the test vehicle based on the high-precision maps and test specification information; control the test vehicle to conduct durability tests based on the initial test plan and driving environment information corresponding to the test vehicle; and acquire vehicle status information corresponding to the test vehicle and send the initial test plan and vehicle status information to the test site control equipment, so that the test site control equipment can control the test vehicle according to the initial test plan and / or the vehicle status information; wherein, the high-precision map is a map corresponding to the test site;

[0200] The test site control equipment is used to receive an initial test plan and vehicle status information sent by the test vehicle; and to control the test vehicle according to the initial test plan and / or the vehicle status information; wherein, the initial test plan is a test plan corresponding to the test vehicle generated by the test vehicle based on a high-precision map and test specification information, and the high-precision map and test specification information are acquired by the test vehicle; the high-precision map is a map corresponding to the test site; the vehicle status information is the status information corresponding to the test vehicle obtained after the test vehicle controls the test vehicle to conduct durability testing according to the initial test plan and the driving environment information corresponding to the test vehicle.

[0201] For example, refer to Figure 7 , Figure 7 Here is a logic block diagram of a vehicle durability testing system according to the present invention, such as... Figure 7 As shown, the onboard host of the test vehicle in the test site acquires driving environment information through environmental detectors in the vehicle. Then, based on high-precision maps and test specifications, the onboard host determines the initial test route and initial test conditions, and generates an initial test plan corresponding to the test vehicle. Subsequently, according to the initial test plan, the onboard host controls the test vehicle to conduct durability tests through the drive control unit in the test vehicle, and acquires the vehicle status information corresponding to the test vehicle through the test detection unit, and sends the initial test plan and vehicle status information to the test site control equipment. Finally, the test site control equipment controls the test vehicle based on the test plan and / or vehicle status information.

[0202] In this embodiment of the invention, the current development level of intelligent driving technology and the actual situation of vehicle reliability and durability testing are fully considered. By the information interaction between the test vehicle and the test site control equipment in the test site, intelligent driving technology is applied to vehicle durability testing. This fully leverages the advantages of intelligent driving technology in a closed test site, saves a lot of human resources, and avoids human interference introduced when conducting durability testing through manual driving, thus ensuring the consistency and reliability of vehicle durability test results.

[0203] This invention provides a vehicle durability testing device, which can be applied to test vehicles, as shown in the following figure. Figure 8 , Figure 8 This is a logic block diagram of a vehicle durability testing device according to the present invention. The device may include:

[0204] The acquisition module 810 is used to acquire high-precision map and test specification information; the high-precision map is a map corresponding to the test site.
