Description

[0002] In modern transportation, vehicle overloading remains a key factor impacting road safety and vehicle lifespan. Statistics show that the number of traffic accidents caused by overloaded vehicles has increased annually, posing a serious threat to public life and property. Furthermore, long-term overloading can accelerate the wear of vehicle components, increase maintenance costs, and shorten the vehicle's overall service life.

[0003] To effectively address vehicle overloading, many vehicle manufacturers have begun integrating overload mitigation features into vehicle control systems. This feature uses sensors to monitor vehicle load conditions and, if overloading is detected, automatically takes measures such as limiting engine power output and adjusting suspension parameters to ensure the vehicle remains relatively safe despite being overloaded.

[0004] However, current verification of a vehicle's overload suppression function can only roughly determine whether the function is activated, but cannot fully and accurately assess its actual operational effectiveness. This limitation has led to numerous issues with the overload suppression function in complex real-world usage scenarios after some vehicles were released to the market. These issues not only fail to fully ensure traffic safety, but can also cause inconvenience or even danger to users due to malfunctioning functions. Summary of the Invention

[0055] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0056] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0057] In an exemplary embodiment, Figure 1 As shown, a method for verifying an overload suppression function is provided. The method is executed by a computer device, specifically a computer device such as a terminal or a server, or a terminal and a server. In the embodiment of the present application, the method includes the following steps 101 to 106. Among them:

[0058] Step 101: The quality monitoring system of the vehicle to be verified collects the total mass true value set and the total mass indication set of the vehicle to be verified, and calculates the average relative total error of the quality monitoring system based on the total mass true value set and the total mass indication set.

[0059] In an embodiment of the present application, the total mass indication value set includes multiple total mass indication values, and the total mass true value set includes multiple total mass true values; the total mass indication value set is collected by a quality monitoring system arranged on the vehicle to be verified. The multiple total mass indication values ​​included in the total mass indication value set can be the total mass indication values ​​collected from the same vehicle to be verified at different times and with different load capacities, or can be the total mass indication values ​​collected from the same model of vehicle to be verified at the same time and with different load capacities. The multiple total mass true values ​​included in the total mass true value set can be the total mass true values ​​collected from the same vehicle to be verified at different times and with different load capacities, or can be the total mass true values ​​collected from the same model of vehicle to be verified at the same time and with different load capacities.

[0060] In the embodiment of the present application, the method for collecting the true value of the total mass of the vehicle to be verified can be:

[0061] Obtain the vehicle curb mass (i.e. vehicle weight) of the vehicle to be verified;

[0062] Obtain the load capacity of the vehicle to be verified (i.e. the mass of the vehicle load);

[0063] The sum of the vehicle's curb mass and loaded mass is determined as the true value of the total mass of the vehicle to be verified.

[0064] The load capacity of the vehicle to be verified may be collected by a load capacity detection device such as a pressure sensor or a strain device provided on the vehicle to be verified.

[0065] For example, the vehicle to be verified may be an air suspension vehicle. In this case, the air pressure information can be read through a pressure sensor (accuracy: 0.05MPa). Based on the calibration relationship between air pressure and load, the vehicle's load capacity can be determined through the Electronic Controlled Air Suspension (ECAS) system.

[0066] When the vehicle to be verified is a vehicle with other suspensions, a strain device is arranged on the frame (or axle housing) of the vehicle to be verified. By measuring the deformation of the load-bearing parts, the load capacity of the vehicle to be verified is obtained using the calibration relationship between deformation and load capacity.

[0067] Alternatively, the true gross mass value of the vehicle to be verified can be collected by measuring it using a floor scale or wheel load meter. When using a floor scale, the scale platform should be large enough to accommodate all the wheels of the vehicle to be verified, and the entrance and exit floors should be level with the platform. When using wheel load meters, ensure that the upper surfaces of the wheel load meters of the vehicle to be verified are on the same horizontal plane.

[0068] As an optional implementation manner, the method of collecting the total mass true value set and the total mass indication value set of the vehicle to be verified through the quality monitoring system of the vehicle to be verified in step 101 may include:

[0069] The vehicle to be verified in a first state, the vehicle to be verified in a second state, and the vehicle to be verified in a third state are respectively driven onto the quality detection equipment in a forward manner and a reverse manner, so that the quality monitoring equipment collects a first forward total mass true value and a first reverse total mass true value corresponding to the first state, a second forward total mass true value and a second reverse total mass true value corresponding to the second state, and a third forward total mass true value and a third reverse total mass true value corresponding to the third state; wherein the first state is unloaded; the second state is: the sum of the load of the vehicle to be verified and the vehicle's own weight is a second reasonable value; the third state is: the sum of the load of the vehicle to be verified and the vehicle's own weight is the first reasonable value;

[0070] acquiring, by a mass monitoring system of the vehicle to be verified, a first forward total mass indication and a first reverse total mass indication corresponding to the first state, a second forward total mass indication and a second reverse total mass indication corresponding to the second state, and a third forward total mass indication and a third reverse total mass indication corresponding to the third state;

[0071] Constructing a total mass truth value set of the vehicle to be verified based on the first forward total mass truth value, the first reverse total mass truth value, the second forward total mass truth value, the second reverse total mass truth value, the third forward total mass truth value, and the third reverse total mass truth value;

[0072] Based on the first forward total mass indication, the first reverse total mass indication, the second forward total mass indication, the second reverse total mass indication, the third forward total mass indication and the third reverse total mass indication, a total mass indication set of the vehicle to be verified is constructed.

[0073] Among them, the implementation of this embodiment, by setting different load states for the vehicle, including no load and a state where the sum of the load and the deadweight is a reasonable value calculated based on the reasonable value of the vehicle's total mass, comprehensively covers various possible operating conditions of the vehicle and ensures the comprehensiveness of data collection. By driving vehicles in different states onto the quality inspection equipment in forward and reverse directions respectively, the true value and indicated value of the total mass of the vehicle in different driving directions can be obtained, effectively eliminating the measurement error that may be caused by the vehicle's driving direction and improving data accuracy. Based on the multiple sets of true values ​​and indicated values ​​collected, corresponding sets are constructed, which provides a rich and reliable data foundation for the subsequent verification and evaluation of the vehicle quality inspection system, helps to more accurately judge the performance of the quality monitoring system, and ensures the scientificity and reliability of vehicle quality inspection work.

[0074] In an embodiment of the present application, the reasonable value of the total vehicle mass can be 39 tons, the first reasonable value can be 110% of the reasonable value of the total vehicle mass (i.e. 43 tons), and the second reasonable value can be 90% of the reasonable value of the total vehicle mass (i.e. 35 tons).

[0075] In the embodiment of the present application, after the first state vehicle to be verified, the second state vehicle to be verified, and the third state vehicle to be verified respectively drive onto the quality inspection equipment in a forward manner and a reverse manner, the following operations can be performed on the first state vehicle to be verified, the second state vehicle to be verified, and the third state vehicle to be verified: after the vehicle to be verified stops, the engine is turned off. If the vehicle to be verified is an electric vehicle, the drive system is turned off; the ignition switch is set to the "ON" / "RUN" state, and the transmission is placed in neutral. Afterwards, the driving direction of the vehicle to be verified when it first drives onto the quality inspection equipment can be determined as the forward direction. It can be seen that the direction opposite to this driving direction is the reverse direction.

[0076] In the embodiment of the present application, the quality inspection equipment may be a floor scale or a wheel load meter, etc.

[0077] As an optional implementation manner, the method of calculating the average relative total error of the quality monitoring system based on the total mass true value set and the total mass indication value set in step 101 may include:

[0078] Calculating the mean of the first forward total mass true value and the first reverse total mass true value to obtain a first total mass true value;

[0079] Calculating the mean of the second forward total mass true value and the second reverse total mass true value to obtain a second total mass true value;

[0080] performing mean calculation on the third forward total mass true value and the third reverse total mass true value to obtain a third total mass true value;

[0081] Calculating a first average relative sub-error using the first total mass true value, the first forward total mass indication, and the first reverse total mass indication;

[0082] Calculating a second average relative sub-error using the second total mass true value, the second forward total mass indication, and the second reverse total mass indication;

[0083] Calculating a third average relative sub-error using the third total mass true value, the third forward total mass indication, and the third reverse total mass indication;

[0084] Averages are calculated for the first average relative sub-error, the second average relative sub-error, and the third average relative sub-error to obtain an average relative total error of the quality monitoring system.

[0085] Among them, implementing this implementation method, by averaging the true values ​​of the forward and reverse total mass of vehicles in different states, can effectively eliminate measurement deviations caused by accidental factors such as the vehicle's driving direction, making the obtained true values ​​of the total mass in each state more representative and accurate. On this basis, the average relative sub-error is calculated for the true value of the total mass in each state and the corresponding forward and reverse total mass indications, fully considering the measurement performance of the system under different load states. Finally, the average of multiple average relative sub-errors is calculated to obtain the average relative total error, which comprehensively reflects the overall measurement accuracy of the quality monitoring system under various working conditions, provides a comprehensive and reliable quantitative indicator for evaluating system performance, helps to promptly discover problems in the system, and then carry out targeted optimization and improvement to ensure the accuracy and reliability of vehicle quality monitoring work.

[0086] In the embodiment of the present application, the calculation formula of the first total mass true value can be:

[0087]

[0088] in, is the first total mass true value, is the first positive total mass true value, is the true value of the first inverse total mass.

[0089] In addition, the second total mass true value and the third total mass true value The calculation method of is the same as that of the first total mass true value, which will not be repeated here.

[0090] In the embodiment of the present application, the calculation formula for the first average relative sub-error can be:

[0091]

[0092] in, is the first average relative sub-error (unit: %), is the first positive total mass indication, It is the first reverse total mass indication.

[0093] In addition, the second mean relative sub-error and the third mean relative sub-error The calculation method of is the same as that of the first average relative sub-error, which will not be repeated here.

[0094] In the embodiment of the present application, the calculation formula of the average relative total error can be:

[0095]

[0096] in, is the average relative total error (in %).

[0097] Step 102: If the average relative total error is less than or equal to the preset error, add a load to the vehicle to be verified until the current true value of the total mass of the vehicle to be verified is greater than a first reasonable value, thereby obtaining an overweight vehicle to be verified.

[0098] In the embodiment of the present application, the first reasonable value is calculated based on the reasonable value of the vehicle's total mass, that is, the current true value of the total mass of the vehicle to be verified as overweight is greater than 43 tons.

[0099] As an optional implementation, if the average relative total error is greater than the preset error, it can be considered that the quality monitoring system has poor accuracy and the overload suppression function verification has failed.

[0100] Step 103: Generate a speed-time curve of the overweight vehicle to be verified during the acceleration test.

[0101] As an optional implementation manner, step 103 of generating the speed-time curve of the overweight vehicle to be verified during the acceleration test may include:

[0102] Based on a preset time interval, collecting multiple instantaneous vehicle speeds during an acceleration test of the overweight vehicle to be verified from an initial speed to a target stable speed; wherein the duration of the acceleration test process is greater than the preset duration;

[0103] A speed-time curve is generated based on the plurality of instantaneous vehicle speeds.

[0104] This implementation method collects multiple instantaneous vehicle speeds at preset time intervals from the initial speed to the target stable speed, ensuring that the acceleration test lasts longer than the preset duration. This allows for comprehensive and detailed capture of the complete and continuous speed changes of overweight vehicles during the acceleration phase. Because the collected data covers a sufficiently long timeframe, it avoids missing critical speed change information due to a too-short test duration, making the data more complete and reliable. Generating a speed-time curve based on this rich instantaneous speed data clearly and intuitively displays the dynamic changes in the acceleration performance of overweight vehicles over time, providing an intuitive and accurate basis for in-depth analysis of the performance characteristics and power output characteristics of overweight vehicles during acceleration, as well as for assessing their safety.

[0105] In the embodiment of the present application, the acceleration test process of the overweight vehicle to be verified can be conducted at a test site suitable for the test. The test site should have a dry and flat road surface, a road slope of no more than 2%, and a road slope variation of no more than 1%. The average wind speed measured at a height of at least 1 meter above the ground should be no more than 3 m / s, and the gust speed should be no more than 10 m / s.

[0106] In this embodiment of the present application, the initial speed can be preset (e.g., 10 km / h) and the target stable speed can be preset (e.g., 20 km / h). This means that the acceleration test process of the overweight vehicle to be verified accelerating from an initial speed of 10 km / h at full throttle to a target stable speed of 20 km / h can be captured, and the duration of the acceleration test process is greater than the preset duration (e.g., 30 seconds). The preset time interval for capturing the instantaneous vehicle speed can be less than 0.1 seconds.

[0107] Please also refer to Figure 2 , Figure 2 It is a speed-time curve diagram, in which the initial speed is 18km / h, that is, the instantaneous speed of the overweight vehicle to be verified is collected from the time when the speed of the overweight vehicle to be verified is 18km / h, and the speed-time curve diagram is drawn. It can be seen that 10 seconds after the instantaneous speed of the overweight vehicle to be verified first reaches the target stable speed of 20km / h, the overweight vehicle to be verified is in the target stable speed driving state. That is, when the overweight vehicle to be verified is in the target stable speed driving state, the speed change of the instantaneous speed is no more than 2 km / h, and the speed change rate of the instantaneous speed is no more than 0.1s. .

[0108] Step 104 : Obtaining from the speed-time curve the average speed, the current maximum speed, and the current maximum speed change rate of the overweight vehicle to be verified after reaching the target stable speed.

[0109] In the embodiment of this application, Figure 2It can be seen that the stage after the overweight vehicle to be verified reaches the target stable speed is the stage 10 seconds after the instantaneous speed of the overweight vehicle to be verified first reaches the target stable speed of 20 km / h.

[0110] As an optional implementation manner, step 104 of obtaining the average speed, current maximum speed, and current maximum speed change rate of the overweight vehicle to be verified after reaching the target stable speed from the speed-time curve may include:

[0111] Obtaining, from the speed-time curve, the first moment when the overweight vehicle to be verified first reaches the target stable speed;

[0112] Based on the first moment, determining a determination time period from the speed-time curve; wherein the first moment is the starting moment of the determination time period, and the duration of the determination time period is a preset determination time period;

[0113] Based on the speed-time curve, the average speed, the current maximum speed and the current maximum speed change rate of the overweight vehicle to be verified corresponding to the determination time period are determined.

[0114] Among them, the implementation of this implementation method clearly takes the first moment when the vehicle first reaches the target stable speed as the starting point, and combines it with the preset judgment time to determine the judgment time period. This setting accurately focuses on the key data collection interval during the stable operation stage of the vehicle, effectively eliminating the interference of the unstable state in the initial acceleration on the data, so that the acquired data can more truly reflect the performance of the vehicle under stable working conditions. Determining the average speed within this time period based on the speed-time curve can intuitively present the overall speed level of the vehicle in the stable stage, providing a key basis for evaluating the vehicle's regular driving efficiency in this state; obtaining the current maximum speed helps to understand the extreme speed that the vehicle can reach during stable operation, which is of great significance for measuring the vehicle's power reserve and potential driving capabilities; and determining the current maximum speed change rate can clearly understand the severity of the vehicle's speed changes in the stable stage, providing an important reference for analyzing the vehicle's driving stability and handling performance.

[0115] In the embodiment of this application, Figure 2 As can be seen, the first moment when the overweight vehicle to be verified first reaches the target stable speed is the moment when the instantaneous speed of the overweight vehicle to be verified first reaches the target stable speed of 20 km / h. The starting time of the determination time period can be 10 seconds after the first moment, and the preset determination time period can be at least 20 seconds.

[0116] In an embodiment of the present application, the average speed may be the average speed of the overweight vehicle to be verified within the determination time period; the current maximum speed may be the maximum instantaneous speed of the overweight vehicle to be verified within the determination time period; and the current maximum speed change rate may be the maximum speed change rate within a time interval of not less than 0.1 s within the determination time period.

[0117] Step 105 : If the average speed is less than or equal to the target maximum stable speed, the current maximum speed is less than or equal to the target maximum speed, and the current maximum speed change rate is less than or equal to the target maximum speed change rate, then multiple average stable speeds of the overweight vehicle to be verified during the stable driving test are collected.

[0118] In the embodiment of the present application, the target maximum stable speed can be 25km / h, the target maximum speed can be 21km / h, and the target maximum speed change rate can be .

[0119] As an optional implementation manner, the method of collecting multiple average stable speeds of the overweight vehicle to be verified during the stable driving test in step 105 may include:

[0120] Collect multiple forward average stable speeds and multiple return average stable speeds of the overweight vehicle to be verified traveling back and forth on the same road at the target stable speed for multiple times; wherein one round trip corresponds to one forward average stable speed and one return average stable speed;

[0121] The forward average stable speed and the return average stable speed of each round trip are averaged to obtain multiple average stable speeds.

[0122] This implementation collects the average forward and return stable speeds of multiple round trips on the same road at the target stable speed. This fully accounts for the impact of road conditions on vehicle driving. Round trips effectively balance the differences in road slope, friction, and other factors that may occur in different directions, making the collected data more comprehensive and objective. Calculating the average forward and return stable speeds for each round trip further eliminates speed fluctuations caused by accidental factors during a single trip. The resulting multiple average stable speeds accurately reflect the vehicle's actual operating speed level during stable driving.

[0123] For example, a round-trip test can be performed five times, with a speed test deviation of no more than ±1% and a sampling interval of less than 0.1s. The overweight vehicle to be verified accelerates to the target stable speed at full throttle and maintains the target stable speed for at least 400m. The average forward stable speed of the overweight vehicle to be verified on that section of road is measured as the measurement result. The same test procedure is then repeated on the same test section in the opposite direction to determine the average return stable speed. The average of the forward and return average stable speeds can then be determined as the average stable speed for the round-trip test.

[0124] As an optional implementation, if one of the following conditions is not true: the average speed is less than or equal to the target maximum stable speed, the current maximum speed is less than or equal to the target maximum speed, and the current maximum speed change rate is less than or equal to the target maximum speed change rate, it can be considered that there is a problem with the overload suppression function of the overweight vehicle to be verified.

[0125] Step 106 : If each average stable speed is less than or equal to the target maximum stable speed and the absolute value of the speed difference between any two average stable speeds is less than or equal to a preset difference, it is determined that the overload suppression function of the vehicle to be verified is normal.

[0126] In the embodiment of the present application, the preset difference may be 3 km / h.

[0127] As an optional implementation, if there is an average stable speed that is greater than the target maximum stable speed, or if the absolute value of the speed difference between any two average stable speeds is greater than a preset difference, it can be considered that there is a problem with the overload suppression function of the overweight vehicle to be verified.

[0128] The implementation of steps 101 to 106 above can effectively reduce misjudgments and greatly improve the accuracy of evaluating the actual operating effect of the overload suppression function. In addition, the present application can also provide a rich and reliable data basis for the verification and evaluation of the vehicle quality detection system. In addition, the present application can also provide comprehensive and reliable quantitative indicators for evaluating system performance, which helps to promptly discover problems with the system. In addition, the present application can also intuitively and clearly present the dynamic changes in the acceleration performance of overweight vehicles over time, providing an intuitive and accurate basis for in-depth analysis of the performance characteristics, power output characteristics of overweight vehicles during the acceleration process and the evaluation of their safety. In addition, the present application can also clearly understand the severity of the speed changes of the vehicle in the stable stage, providing an important reference for analyzing the vehicle's driving stability and handling performance. In addition, the present application can also accurately reflect the actual operating speed level of the vehicle in a stable driving state.

The solution provided by this device is similar to the solution described in the method described above. Therefore, the specific limitations in one or more embodiments of the overload suppression function verification device provided below can be found in the above-mentioned limitations of the overload suppression function verification method and will not be repeated here.

[0130] In an exemplary embodiment, Figure 3 As shown, an overload suppression function verification device is provided, comprising:

[0131] A calculation unit 301 is configured to collect a total mass true value set and a total mass indication value set of the vehicle to be verified through a quality monitoring system of the vehicle to be verified, and calculate an average relative total error of the quality monitoring system based on the total mass true value set and the total mass indication value set;

[0132] The load unit 302 is configured to add a load to the vehicle to be verified if the average relative total error is less than or equal to a preset error until the current true value of the total mass of the vehicle to be verified is greater than a first reasonable value, thereby obtaining an overweight vehicle to be verified;

[0133] A generating unit 303 is configured to generate a speed-time curve of the overweight vehicle to be verified during the acceleration test;

[0134] An acquiring unit 304 is configured to acquire, from the speed-time curve, an average speed, a current maximum speed, and a rate of change of the current maximum speed of the overweight vehicle to be verified after reaching a target stable speed;

[0135] The collecting unit 305 is configured to collect a plurality of average stable speeds of the overweight vehicle to be verified during the stable driving test if the average speed is less than or equal to the target maximum stable speed, the current maximum speed is less than or equal to the target maximum speed, and the current maximum speed change rate is less than or equal to the target maximum speed change rate.

[0136] The determining unit 306 is configured to determine that the overload suppression function of the vehicle to be verified is normal if each average stable speed is less than or equal to the target maximum stable speed and the absolute value of the speed difference between any two average stable speeds is less than or equal to a preset difference.

[0137] As an optional implementation manner, the calculation unit 301 may collect the total mass true value set and the total mass indication value set of the vehicle to be verified through the quality monitoring system of the vehicle to be verified in the following manner:

[0138] The vehicle to be verified in the first state, the vehicle to be verified in the second state, and the vehicle to be verified in the third state are respectively driven onto the quality detection equipment in a forward manner and a reverse manner, so that the quality monitoring equipment collects a first forward total mass true value and a first reverse total mass true value corresponding to the first state, a second forward total mass true value and a second reverse total mass true value corresponding to the second state, and a third forward total mass true value and a third reverse total mass true value corresponding to the third state; wherein the first state is unloaded; the second state is: the sum of the load of the vehicle to be verified and the vehicle's own weight is a second reasonable value; the third state is: the sum of the load of the vehicle to be verified and the vehicle's own weight is the first reasonable value; wherein the first reasonable value is calculated based on the reasonable value of the total vehicle mass;

[0139] acquiring, by a mass monitoring system of the vehicle to be verified, a first forward total mass indication and a first reverse total mass indication corresponding to the first state, a second forward total mass indication and a second reverse total mass indication corresponding to the second state, and a third forward total mass indication and a third reverse total mass indication corresponding to the third state;

[0140] Constructing a total mass truth value set of the vehicle to be verified based on the first forward total mass truth value, the first reverse total mass truth value, the second forward total mass truth value, the second reverse total mass truth value, the third forward total mass truth value, and the third reverse total mass truth value;

[0141] Based on the first forward total mass indication, the first reverse total mass indication, the second forward total mass indication, the second reverse total mass indication, the third forward total mass indication and the third reverse total mass indication, a total mass indication set of the vehicle to be verified is constructed.

[0142] Among them, the implementation of this embodiment, by setting different load states for the vehicle, including no load and a state where the sum of the load and the deadweight is a reasonable value calculated based on the reasonable value of the vehicle's total mass, comprehensively covers various possible operating conditions of the vehicle and ensures the comprehensiveness of data collection. By driving vehicles in different states onto the quality inspection equipment in forward and reverse directions respectively, the true value and indicated value of the total mass of the vehicle in different driving directions can be obtained, effectively eliminating the measurement error that may be caused by the vehicle's driving direction and improving data accuracy. Based on the multiple sets of true values ​​and indicated values ​​collected, corresponding sets are constructed, which provides a rich and reliable data foundation for the subsequent verification and evaluation of the vehicle quality inspection system, helps to more accurately judge the performance of the quality monitoring system, and ensures the scientificity and reliability of vehicle quality inspection work.

[0143] As an optional implementation manner, the calculation unit 301 calculates the average relative total error of the quality monitoring system based on the total mass true value set and the total mass indication value set in a manner that is specifically:

[0144] Calculating the mean of the first forward total mass true value and the first reverse total mass true value to obtain a first total mass true value;

[0145] Calculating the mean of the second forward total mass true value and the second reverse total mass true value to obtain a second total mass true value;

[0146] performing mean calculation on the third forward total mass true value and the third reverse total mass true value to obtain a third total mass true value;

[0147] Calculating a first average relative sub-error using the first total mass true value, the first forward total mass indication, and the first reverse total mass indication;

[0148] Calculating a second average relative sub-error using the second total mass true value, the second forward total mass indication, and the second reverse total mass indication;

[0149] Calculating a third average relative sub-error using the third total mass true value, the third forward total mass indication, and the third reverse total mass indication;

[0150] Averages are calculated for the first average relative sub-error, the second average relative sub-error, and the third average relative sub-error to obtain an average relative total error of the quality monitoring system.

[0151] Among them, implementing this implementation method, by averaging the true values ​​of the forward and reverse total mass of vehicles in different states, can effectively eliminate measurement deviations caused by accidental factors such as the vehicle's driving direction, making the obtained true values ​​of the total mass in each state more representative and accurate. On this basis, the average relative sub-error is calculated for the true value of the total mass in each state and the corresponding forward and reverse total mass indications, fully considering the measurement performance of the system under different load states. Finally, the average of multiple average relative sub-errors is calculated to obtain the average relative total error, which comprehensively reflects the overall measurement accuracy of the quality monitoring system under various working conditions, provides a comprehensive and reliable quantitative indicator for evaluating system performance, helps to promptly discover problems in the system, and then carry out targeted optimization and improvement to ensure the accuracy and reliability of vehicle quality monitoring work.

[0152] As an optional implementation manner, the generation unit 303 may generate the speed-time curve of the overweight vehicle to be verified during the acceleration test in the following manner:

[0153] Based on a preset time interval, collecting multiple instantaneous vehicle speeds during an acceleration test of the overweight vehicle to be verified from an initial speed to a target stable speed; wherein the duration of the acceleration test process is greater than the preset duration;

[0154] A speed-time curve is generated based on the plurality of instantaneous vehicle speeds.

[0155] This implementation method collects multiple instantaneous vehicle speeds at preset time intervals from the initial speed to the target stable speed, ensuring that the acceleration test lasts longer than the preset duration. This allows for comprehensive and detailed capture of the complete and continuous speed changes of overweight vehicles during the acceleration phase. Because the collected data covers a sufficiently long timeframe, it avoids missing critical speed change information due to a too-short test duration, making the data more complete and reliable. Generating a speed-time curve based on this rich instantaneous speed data clearly and intuitively displays the dynamic changes in the acceleration performance of overweight vehicles over time, providing an intuitive and accurate basis for in-depth analysis of the performance characteristics and power output characteristics of overweight vehicles during acceleration, as well as for assessing their safety.

[0156] As an optional implementation manner, the acquisition unit 304 may acquire the average speed, the current maximum speed, and the current maximum speed change rate of the overweight vehicle to be verified after reaching the target stable speed from the speed-time curve in the following manner:

[0157] Obtaining, from the speed-time curve, the first moment when the overweight vehicle to be verified first reaches the target stable speed;

[0158] Based on the first moment, determining a determination time period from the speed-time curve; wherein the first moment is the starting moment of the determination time period, and the duration of the determination time period is a preset determination time period;

[0159] Based on the speed-time curve, the average speed, the current maximum speed and the current maximum speed change rate of the overweight vehicle to be verified corresponding to the determination time period are determined.

[0160] Among them, the implementation of this implementation method clearly takes the first moment when the vehicle first reaches the target stable speed as the starting point, and combines it with the preset judgment time to determine the judgment time period. This setting accurately focuses on the key data collection interval during the stable operation stage of the vehicle, effectively eliminating the interference of the unstable state in the initial acceleration on the data, so that the acquired data can more truly reflect the performance of the vehicle under stable working conditions. Determining the average speed within this time period based on the speed-time curve can intuitively present the overall speed level of the vehicle in the stable stage, providing a key basis for evaluating the vehicle's regular driving efficiency in this state; obtaining the current maximum speed helps to understand the extreme speed that the vehicle can reach during stable operation, which is of great significance for measuring the vehicle's power reserve and potential driving capabilities; and determining the current maximum speed change rate can clearly understand the severity of the vehicle's speed changes in the stable stage, providing an important reference for analyzing the vehicle's driving stability and handling performance.

[0161] As an optional implementation manner, the collecting unit 305 collects multiple average stable speeds of the overweight vehicle to be verified during the stable driving test in the following manner:

[0162] Collect multiple forward average stable speeds and multiple return average stable speeds of the overweight vehicle to be verified traveling back and forth on the same road at the target stable speed for multiple times; wherein one round trip corresponds to one forward average stable speed and one return average stable speed;

[0163] The forward average stable speed and the return average stable speed of each round trip are averaged to obtain multiple average stable speeds.

[0164] This implementation collects the average forward and return stable speeds of multiple round trips on the same road at the target stable speed. This fully accounts for the impact of road conditions on vehicle driving. Round trips effectively balance the differences in road slope, friction, and other factors that may occur in different directions, making the collected data more comprehensive and objective. Calculating the average forward and return stable speeds for each round trip further eliminates speed fluctuations caused by accidental factors during a single trip. The resulting multiple average stable speeds accurately reflect the vehicle's actual operating speed level during stable driving.

[0165] The implementation of the above-mentioned embodiment can effectively reduce misjudgments and greatly improve the accuracy of evaluating the actual operating effect of the overload suppression function. In addition, the present application can also provide a rich and reliable data basis for the verification and evaluation of the vehicle quality detection system. In addition, the present application can also provide comprehensive and reliable quantitative indicators for evaluating system performance, which helps to promptly discover problems with the system. In addition, the present application can also intuitively and clearly present the dynamic changes in the acceleration performance of overweight vehicles over time, and provide an intuitive and accurate basis for in-depth analysis of the performance characteristics, power output characteristics of overweight vehicles during the acceleration process and the evaluation of their safety. In addition, the present application can also clearly understand the severity of the speed change of the vehicle in the stable stage, and provide an important reference for analyzing the vehicle's driving stability and handling performance. In addition, the present application can also accurately reflect the actual operating speed level of the vehicle in a stable driving state.
