Description

[0002] In the field of modern transportation, vehicle overloading has always been a key factor affecting road traffic safety and vehicle service life. According to relevant statistics, the number of traffic accidents caused by vehicle overloading has increased year by year, seriously threatening the safety of people's lives and property. At the same time, long-term overloading will also lead to accelerated wear of vehicle components, increase vehicle maintenance costs, and shorten the overall service life of the vehicle. In order to effectively deal with the problem of vehicle overloading, many vehicle manufacturers have begun to introduce overload suppression functions in vehicle control systems. This function is designed to monitor the vehicle load through sensors, and once overloading is detected, it automatically takes measures such as limiting engine power output and adjusting suspension system parameters to ensure that the vehicle can still drive relatively safely in an overloaded state.

[0003] However, the current verification of the vehicle overload suppression function can only roughly determine whether the overload suppression function is activated, but cannot fully and accurately evaluate the actual operating effect of the function. The limitations of this verification method have led to many problems with the overload suppression function of some vehicles after they were put on the market in actual complex usage scenarios. Not only did it fail to fully play its role in ensuring traffic safety, it may also cause inconvenience or even danger to users due to functional abnormalities. Summary of the invention

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] In order to make the above-mentioned objects, 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.

[0021] In an exemplary embodiment, Figure 1 As shown, a method for verifying an overload suppression function is provided, which is executed by a computer device, and can be executed by a computer device such as a terminal or a server alone, or by a terminal and a server together. In the embodiment of the present application, the following steps 101 to 106 are included. Among them: Step 101, collecting a total mass true value set and a total mass indication set of the vehicle to be verified through the quality monitoring system of the vehicle to be verified, and calculating the average relative total error of the quality monitoring system based on the total mass true value set and the total mass indication set.

[0022] In an embodiment of the present application, the total mass indication set includes multiple total mass indications, and the total mass true value set includes multiple total mass true values; the total mass indication set is collected by a mass monitoring system arranged on the vehicle to be verified. The multiple total mass indications included in the total mass indication set can be total mass indications collected from the same vehicle to be verified at different times and with different load masses, or can be total mass indications collected from the same model of vehicle to be verified at the same time and with different load masses. The multiple total mass true values ​​included in the total mass true value set can be total mass true values ​​collected from the same vehicle to be verified at different times and with different load masses, or can be total mass true values ​​collected from the same model of vehicle to be verified at the same time and with different load masses.

[0023] In the embodiment of the present application, the method for collecting the true value of the total mass of the vehicle to be verified may be: Obtain the vehicle curb weight (i.e. vehicle weight) of the vehicle to be verified; Obtain the load capacity of the vehicle to be verified (i.e. the mass of the vehicle load); The sum of the vehicle's curb weight and load mass is determined as the true value of the total mass of the vehicle to be verified.

[0024] The load mass of the vehicle to be verified may be collected by a load mass detection device such as a pressure sensor or a strain device provided on the vehicle to be verified.

[0025] 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 load of the vehicle can be obtained through the Electronic Controlled Air Suspension (ECAS) system. 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, and the load capacity of the vehicle to be verified is obtained by measuring the deformation of the load-bearing part and using the calibration relationship between the deformation and the load capacity.

[0026] Optionally, the method for collecting the true value of the total mass of the vehicle to be verified can also be: using a floor scale or a wheel load meter to measure the true value of the total mass of the vehicle to be verified. When using a floor scale, the scale platform area should be able to accommodate all the wheels of the vehicle to be verified, and the floor of the scale platform entrance and exit should be kept at the same level as the platform; when using a wheel load meter, it should be ensured that the upper planes of the wheel load meters of the vehicle to be verified are in the same horizontal plane.

[0027] 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 mass monitoring system of the vehicle to be verified in step 101 may include: 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 the first forward total mass true value and the first reverse total mass true value corresponding to the first state, the second forward total mass true value and the second reverse total mass true value corresponding to the second state, and the third forward total mass true value and the 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; The first forward total mass indication and the first reverse total mass indication corresponding to the first state, the second forward total mass indication and the second reverse total mass indication corresponding to the second state, and the third forward total mass indication and the third reverse total mass indication corresponding to the third state are acquired by the mass monitoring system of the vehicle to be verified; 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; 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.

[0028] Among them, by implementing this implementation method, by setting different load states for the vehicle, including no-load and the state where the sum of the load and the deadweight is a reasonable value calculated based on the reasonable value of the total mass of the vehicle, it comprehensively covers various operating conditions that the vehicle may be in, ensuring 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 indication 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 driving direction of the vehicle and improving data accuracy. Constructing corresponding sets based on the collected multiple sets of true values ​​and indications provides a rich and reliable data basis for the subsequent verification and evaluation of the vehicle quality inspection system, which helps to more accurately judge the performance of the quality monitoring system and ensure the scientificity and reliability of vehicle quality inspection work.

[0029] In this embodiment of the present application, the reasonable value of the total vehicle mass may be 39 tons, the first reasonable value may be 110% of the reasonable value of the total vehicle mass (ie 43 tons), and the second reasonable value may be 90% of the reasonable value of the total vehicle mass (ie 35 tons).

[0030] 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 drive onto the quality inspection equipment in a forward manner and a reverse manner respectively, 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: the engine is turned off after the vehicle to be verified stops, and 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 set to neutral. After that, the driving direction of the vehicle to be verified when it first drives onto the quality monitoring equipment can be determined as the forward direction, and it can be seen that the direction opposite to the driving direction is the reverse direction.

[0031] In the embodiment of the present application, the quality inspection equipment may be a floor scale or a wheel load meter, etc.

[0032] 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: Performing mean calculation on the first forward total mass true value and the first reverse total mass true value to obtain a first total mass true value; Performing mean calculation on the second forward total mass true value and the second reverse total mass true value to obtain a second total mass true value; 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; Using the first total mass true value, the first forward total mass indication, and the first reverse total mass indication, a first average relative sub-error is calculated; Using the second total mass true value, the second forward total mass indication, and the second reverse total mass indication, a second average relative sub-error is calculated; Using the third total mass true value, the third forward total mass indication, and the third reverse total mass indication, a third average relative sub-error is calculated; The first average relative sub-error, the second average relative sub-error and the third average relative sub-error are averaged to obtain an average relative total error of the quality monitoring system.

[0033] Among them, by implementing this implementation method, by averaging the true values ​​of the forward and reverse total mass of vehicles in different states, the measurement deviation caused by accidental factors such as the vehicle's driving direction can be effectively eliminated, making the total mass true value of each state more representative and accurate. On this basis, the average relative sub-error is calculated for the total mass true value of 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 relative total error is obtained by averaging multiple average relative sub-errors, 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, and helps to promptly discover problems in the system, and then optimize and improve it in a targeted manner to ensure the accuracy and reliability of vehicle quality monitoring work.

[0034] In the embodiment of the present application, the calculation formula of the first total mass true value may be: in, is the first total mass true value, is the first positive total mass true value, is the true value of the first reverse total mass.

[0035] 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.

[0036] In the embodiment of the present application, the calculation formula of the first average relative sub-error can be: in, is the first average relative sub-error (in %), is the first positive total mass indication, It is the first reverse total mass indication.

[0037] In addition, the second average 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.

[0038] In the embodiment of the present application, the calculation formula of the average relative total error can be: in, is the average relative total error (in %).

[0039] Step 102: if the average relative total error is less than or equal to a preset error, then 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.

[0040] In the embodiment of the present application, the first reasonable value is calculated based on the reasonable value of the total mass of the vehicle, that is, the current true value of the total mass of the overweight vehicle to be verified is greater than 43 tons.

[0041] 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.

[0042] Step 103, generating a speed-time curve of the overweight vehicle to be verified during the acceleration test.

[0043] As an optional implementation manner, the method of generating the speed-time curve of the overweight vehicle to be verified during the acceleration test in step 103 may include: 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; A speed-time curve is generated based on the plurality of instantaneous vehicle speeds.

[0044] Among them, by implementing this implementation method, multiple instantaneous vehicle speeds during the driving process from the initial speed to the target stable speed are collected at preset time intervals, and the duration of the acceleration test process is ensured to be greater than the preset duration, which can comprehensively and meticulously capture the complete and continuous speed changes of the overweight vehicle during the acceleration stage. Since the collected data covers a sufficiently long time range, it avoids missing key speed change information due to too short a test duration, making the data more complete and reliable. Based on these rich instantaneous vehicle speed data, the speed-time curve is generated, which can intuitively and clearly present the dynamic changes of the acceleration performance of the overweight vehicle over time, providing an intuitive and accurate basis for in-depth analysis of the performance characteristics and power output characteristics of the overweight vehicle during the acceleration process and the evaluation of its safety.

[0045] In the embodiment of the present application, the acceleration test process of the overweight vehicle to be verified can be carried out at a test site suitable for the test. The road surface of the test site should be dry and flat, with a road slope of no more than 2% and a road slope change of no more than 1%; the average wind speed measured at a position at least 1 m above the ground is no more than 3 m / s, and the gust wind speed is no more than 10 m / s.

[0046] In the embodiment of the present application, the initial speed can be preset (e.g., 10km / h), and the target stable speed can be preset (e.g., 20km / h), that is, the acceleration test process of the overweight vehicle to be verified from the initial speed of 10km / h to the target stable speed of 20km / h can be collected, and the duration of the acceleration test process is greater than the preset duration (e.g., 30s). The preset time interval for collecting the instantaneous vehicle speed can be less than 0.1s.

[0047] Please also read Figure 2 , Figure 2 It is a speed-time curve, where the initial speed is 18 km / 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 18 km / h, and the speed-time curve is drawn. It can be seen that the overweight vehicle to be verified is in the target stable speed driving state 10 seconds after the instantaneous speed of the overweight vehicle to be verified first reaches the target stable speed of 20 km / h. 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 not greater than 2 km / h, and the speed change rate of the instantaneous speed within a time of not less than 0.1 s is not greater than .

[0048] 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.

[0049] In the present application embodiment, from 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 20km / h.

[0050] As an optional implementation manner, the method of obtaining 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 step 104 may include: Obtaining, from the speed-time curve, the first moment when the overweight vehicle to be verified reaches the target stable speed for the first time; 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; 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.

[0051] 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 determines the judgment time period in combination with the preset judgment time. This setting accurately focuses on the key data collection interval in 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 in 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 regular driving efficiency of the vehicle in this state; obtaining the current maximum speed helps to understand the extreme speed that the vehicle can reach in stable operation, which is of great significance for measuring the vehicle's power reserve and potential driving ability; and determining the current maximum speed change rate can clearly understand the severity of the vehicle's speed change in the stable stage, providing an important reference for analyzing the vehicle's driving stability and handling performance.

[0052] In the present application embodiment, from Figure 2 It can be seen that the first moment when the overweight vehicle to be verified reaches the target stable speed for the first time is the moment when the instantaneous speed of the overweight vehicle to be verified reaches the target stable speed of 20 km / h for the first time. The starting moment of the determination time period can be 10 seconds after the first moment, and the preset determination time of the determination time period can be at least 20 seconds.

[0053] 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; 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.

[0054] 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 collect multiple average stable speeds of the overweight vehicle to be verified during the stable driving test.

[0055] In the embodiment of the present application, the target maximum stable speed can be 25 km / h, the target maximum speed can be 21 km / h, and the target maximum speed change rate can be .

[0056] 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: 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 multiple times at the target stable speed; wherein one round trip corresponds to one forward average stable speed and one return average stable speed; The average forward stable speed and the return stable speed of each round trip are averaged to obtain multiple average stable speeds.

[0057] Among them, by implementing this implementation method, the forward and return average stable speeds of the vehicle traveling back and forth on the same road at the target stable speed for multiple times are collected, which fully considers the impact of the road environment on the vehicle's driving state. The round-trip driving can effectively balance the differences that may be caused by factors such as road slope and friction in different directions, making the collected data more comprehensive and objective. The average forward and return average stable speeds of each round trip are calculated to further eliminate the speed fluctuations caused by accidental factors in a single trip. The multiple average stable speeds obtained can accurately reflect the actual operating speed level of the vehicle under stable driving conditions.

[0058] For example, the round-trip test can be performed five times in total, with the speed test deviation not greater than ±1% and the sampling time interval 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 this road section is measured as the measurement result; then the same test procedure is used to test the opposite direction of the same test section to obtain the return average stable speed, and then the average of the forward average stable speed and the return average stable speed can be determined as the average stable speed of this round-trip test.

[0059] As an optional implementation, if one of the following 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, then it can be considered that there is a problem with the overload suppression function of the overweight vehicle to be verified.

[0060] 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.

In addition, the present application can also accurately reflect the actual operating speed level of the vehicle under stable driving conditions.

[0064] Based on the same inventive concept, the embodiment of the present application also provides an overload suppression function verification device for implementing the overload suppression function verification method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more overload suppression function verification device embodiments provided below can refer to the limitations of the overload suppression function verification method above, and will not be repeated here.

[0065] In an exemplary embodiment, Figure 3 As shown, an overload suppression function verification device is provided, comprising: A calculation unit 301 is used to collect a total mass true value set and a total mass indication set of the vehicle to be verified through a mass 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 set; The load unit 302 is used 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 total mass true value of the vehicle to be verified is greater than a first reasonable value, thereby obtaining an overweight vehicle to be verified; A generating unit 303, used for generating a speed-time curve of the overweight vehicle to be verified during the acceleration test; An acquisition unit 304 is used to acquire, from the speed-time curve, an average speed, a current maximum speed, and a current maximum speed change rate of the overweight vehicle to be verified after reaching a target stable speed; The collecting unit 305 is used 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. The determination 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.

[0066] As an optional implementation manner, the calculation unit 301 collects 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: 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 the first forward total mass true value and the first reverse total mass true value corresponding to the first state, the second forward total mass true value and the second reverse total mass true value corresponding to the second state, and the third forward total mass true value and the 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 mass of the vehicle; The first forward total mass indication and the first reverse total mass indication corresponding to the first state, the second forward total mass indication and the second reverse total mass indication corresponding to the second state, and the third forward total mass indication and the third reverse total mass indication corresponding to the third state are acquired by the mass monitoring system of the vehicle to be verified; 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; 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.

[0067] Among them, by implementing this implementation method, by setting different load states for the vehicle, including no-load and the state where the sum of the load and the deadweight is a reasonable value calculated based on the reasonable value of the total mass of the vehicle, it comprehensively covers various operating conditions that the vehicle may be in, ensuring 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 indication 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 driving direction of the vehicle and improving data accuracy. Constructing corresponding sets based on the collected multiple sets of true values ​​and indications provides a rich and reliable data basis for the subsequent verification and evaluation of the vehicle quality inspection system, which helps to more accurately judge the performance of the quality monitoring system and ensure the scientificity and reliability of vehicle quality inspection work.

[0068] 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: Performing mean calculation on the first forward total mass true value and the first reverse total mass true value to obtain a first total mass true value; Performing mean calculation on the second forward total mass true value and the second reverse total mass true value to obtain a second total mass true value; 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; Using the first total mass true value, the first forward total mass indication, and the first reverse total mass indication, a first average relative sub-error is calculated; Using the second total mass true value, the second forward total mass indication, and the second reverse total mass indication, a second average relative sub-error is calculated; Using the third total mass true value, the third forward total mass indication, and the third reverse total mass indication, a third average relative sub-error is calculated; The first average relative sub-error, the second average relative sub-error and the third average relative sub-error are averaged to obtain an average relative total error of the quality monitoring system.

[0069] Among them, by implementing this implementation method, by averaging the true values ​​of the forward and reverse total mass of vehicles in different states, the measurement deviation caused by accidental factors such as the vehicle's driving direction can be effectively eliminated, making the total mass true value of each state more representative and accurate. On this basis, the average relative sub-error is calculated for the total mass true value of 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 relative total error is obtained by averaging multiple average relative sub-errors, 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, and helps to promptly discover problems in the system, and then optimize and improve it in a targeted manner to ensure the accuracy and reliability of vehicle quality monitoring work.

[0070] As an optional implementation manner, the generation unit 303 generates the speed-time curve of the overweight vehicle to be verified during the acceleration test in the following manner: 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; A speed-time curve is generated based on the plurality of instantaneous vehicle speeds.

[0071] Among them, by implementing this implementation method, multiple instantaneous vehicle speeds during the driving process from the initial speed to the target stable speed are collected at preset time intervals, and the duration of the acceleration test process is ensured to be greater than the preset duration, which can comprehensively and meticulously capture the complete and continuous speed changes of the overweight vehicle during the acceleration stage. Since the collected data covers a sufficiently long time range, it avoids missing key speed change information due to too short a test duration, making the data more complete and reliable. Based on these rich instantaneous vehicle speed data, the speed-time curve is generated, which can intuitively and clearly present the dynamic changes of the acceleration performance of the overweight vehicle over time, providing an intuitive and accurate basis for in-depth analysis of the performance characteristics and power output characteristics of the overweight vehicle during the acceleration process and the evaluation of its safety.

[0072] As an optional implementation manner, the acquisition unit 304 acquires 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: Obtaining, from the speed-time curve, the first moment when the overweight vehicle to be verified reaches the target stable speed for the first time; 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; 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.

[0073] 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 determines the judgment time period in combination with the preset judgment time. This setting accurately focuses on the key data collection interval in 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 in 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 regular driving efficiency of the vehicle in this state; obtaining the current maximum speed helps to understand the extreme speed that the vehicle can reach in stable operation, which is of great significance for measuring the vehicle's power reserve and potential driving ability; and determining the current maximum speed change rate can clearly understand the severity of the vehicle's speed change in the stable stage, providing an important reference for analyzing the vehicle's driving stability and handling performance.

[0074] As an optional implementation manner, the collection unit 305 collects multiple average stable speeds of the overweight vehicle to be verified during the stable driving test in the following manner: 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 multiple times at the target stable speed; wherein one round trip corresponds to one forward average stable speed and one return average stable speed; The average forward stable speed and the return stable speed of each round trip are averaged to obtain multiple average stable speeds.

[0075] Among them, by implementing this implementation method, the forward and return average stable speeds of the vehicle traveling back and forth on the same road at the target stable speed for multiple times are collected, which fully considers the impact of the road environment on the vehicle's driving state. The round-trip driving can effectively balance the differences that may be caused by factors such as road slope and friction in different directions, making the collected data more comprehensive and objective. The average forward and return average stable speeds of each round trip are calculated to further eliminate the speed fluctuations caused by accidental factors in a single trip. The multiple average stable speeds obtained can accurately reflect the actual operating speed level of the vehicle under stable driving conditions.

[0076] The implementation of the above-mentioned implementation mode 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 intuitively and clearly present the dynamic changes of 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 and safety of overweight vehicles during the acceleration process. 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 driving stability and handling performance of the vehicle. In addition, the present application can also accurately reflect the actual operating speed level of the vehicle in a stable driving state.
