[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0025] Combine the following Figure 1-Figure 6 The vehicle axle load determination method, device and apparatus of the present invention are described.
[0026] In order to facilitate a clearer understanding of the technical solutions of the embodiments of the present application, some technical contents related to the embodiments of the present application are first introduced.
[0027] At present, axle load calculation is mostly based on the measurement of center of mass and wheelbase. The estimation error of center of mass is large, and multiple tests and wheelbase measurements are required. The process of calculating axle load by determining wheelbase by center of mass is cumbersome and increases costs. There are also methods to calculate axle load based on air spring pressure. This method does not take into account the influence of factors such as height and the trend of spring stiffness change when it rises and falls, and the error is large.
[0028] In summary, the existing axle load calculation scheme has the following disadvantages: A. Based on the center of mass and wheelbase, the center of mass estimation error is large.
[0029] B. Based on the center of mass and wheelbase, the process is cumbersome and increases costs.
[0030] C. The axle load is estimated based on pressure, without considering the effects of factors such as height on the axle load.
[0031] D. The influence of factors such as the rise or fall of the spring and the different trends of the spring stiffness changes are not taken into account.
[0032] Figure 1 is one of the flow charts of the vehicle axle load determination method provided by the present invention, such as Figure 1 As shown, the method includes the following: Step 101: Establish a vehicle axle load prediction model based on the pressure of the air spring, the stiffness variation coefficient of the air spring and the vehicle height information.
[0033] Specifically, in the embodiment of the present application, a vehicle axle load prediction model is established based on the pressure of the air spring, the stiffness change coefficient of the air spring and the vehicle height information. That is, the present application is different from the existing method of calculating the vehicle axle load based on the center of mass and wheelbase. By considering the rise and fall of the height of the ECAS air spring of a single axle, the different trends of its spring stiffness characteristics, and the characteristics of the pressure change accordingly, a vehicle axle load prediction model is established, so that the influencing factors of the vehicle axle load can be more accurately and comprehensively reflected, and the vehicle axle load can be predicted more accurately.
[0034] For example, the present application takes into account the problem of large errors in calculating the vehicle axle load based on the center of mass and wheelbase, and turns to the vehicle height information and air spring pressure, and comprehensively considers the change in spring rigidity to jointly establish an axle load calculation model, thereby effectively improving the accuracy of the vehicle axle load prediction results. Optionally, the height information of the vehicle can be determined by a potentiometer height sensor. Optionally, the height sensor mechanically connects the axle and the frame, and drives the potentiometer slider to move when the height changes. The initial median height is 860mm, and the rise and fall adjustment is performed. The collected height signal is sent to the vehicle's axle load prediction model as input. Optionally, the pressure signal of the air spring is monitored by a pressure detection unit, and the collected signal is sent to the vehicle's axle load prediction model block as input. It should be noted that the height sensor and the pressure sensor work together to ensure the dynamic balance between the vehicle height and the air spring pressure. For example, keep the vehicle body at a certain height. When the height sensor detects that the vehicle body has dropped, the ECU will monitor the air pressure through the pressure sensor and inflate the air spring to restore the height.
[0035] Step 102: Determine the axle load prediction result of the vehicle according to the axle load prediction model of the vehicle.
[0036] Specifically, after the embodiment of the present application establishes the vehicle's axle load prediction model based on the pressure of the air spring, the stiffness variation coefficient of the air spring and the vehicle height information, the vehicle's axle load prediction model can be used to accurately predict the vehicle's axle load, effectively overcoming the problem of large errors in calculating the vehicle's axle load based on the center of mass and wheelbase.
[0037] The method of the above embodiment is based on vehicle height information and air spring pressure, and takes into account the change in spring stiffness, to jointly establish an axle load prediction model, which accurately and comprehensively reflects the factors affecting the vehicle axle load, thereby effectively improving the accuracy of the vehicle axle load prediction results and effectively overcoming the problem of large errors in calculating the vehicle axle load based on the center of mass and wheelbase.
[0038] In some embodiments, the axle load prediction model of the vehicle includes: F = α × (h-h0) × β × P Among them, F represents the predicted result of the vehicle axle load; α represents the cross-sectional area of the air spring; h-h0 represents the height change information of the vehicle; β represents the stiffness change coefficient of the air spring; and P represents the pressure of the air spring.
[0039] Specifically, in the embodiment of the present application, the relationship between the axle load and the air spring characteristics and the pressure and height changes is taken into account to establish an axle load prediction model, which is simple, easy to implement and has strong real-time performance. Optionally, the axle load prediction model includes: F = α × (h-h0) × β × P; Among them, F represents the predicted result of the vehicle axle load; α represents the cross-sectional area of the air spring; h-h0 represents the height change information of the vehicle, h represents the current height of the vehicle, and h0 represents the initial median height; β represents the rigidity change coefficient of the air spring; and P represents the pressure of the air spring. That is, this application is based on the vehicle height information and the air spring pressure, and takes into account the change of spring rigidity to jointly establish an axle load prediction model, which can more accurately and comprehensively reflect the influencing factors of the vehicle axle load, and can also more accurately predict the vehicle axle load.
[0040] The method of the above embodiment is based on vehicle height information and air spring pressure, and takes into account the change in spring stiffness to jointly establish an axle load prediction model, which can more accurately and comprehensively reflect the factors affecting the vehicle axle load, and can also more accurately predict the vehicle axle load.
[0041] In some embodiments, after determining the axle load prediction result of the vehicle, the method further includes: Determine the correction item of the vehicle axle load prediction result; the correction item is used to correct the influence of the weight of vehicle parts on the vehicle axle load; The axle load prediction result of the vehicle is updated according to the correction item of the axle load prediction result of the vehicle.
[0042] Specifically, after determining the axle load prediction result of the vehicle based on the axle load prediction model of the vehicle, the present application further considers the influence of unsprung component factors, adds unsprung component correction items, and updates the axle load prediction result, so that the vehicle axle load can be predicted more accurately. Optionally, there are wheels and other sensors under the air spring, which will affect the axle load prediction result. Therefore, the present application can effectively improve the accuracy of the vehicle axle load prediction result by adding correction items to the axle load prediction result of the vehicle. Optionally, the axle load prediction result output by the axle load prediction model can be compared with the axle load measured by the axle load meter, and the difference between the two can be used as a correction item for the axle load prediction result of the vehicle.
[0043] For example, the predicted axle load results when the vehicle height rises and falls are fitted and checked with the values measured in the actual axle load meter to obtain the correction error, and the load correction value f is updated iteratively multiple times until the model calculation results are within the allowable range of axle load error.
[0044] The method of the above embodiment takes into account the influence of unsprung components, adds unsprung component correction items, corrects the influence of the weight of vehicle components on the vehicle axle load, updates the axle load prediction results, and effectively improves the accuracy of the vehicle axle load prediction results.
[0045] In some embodiments, the vehicle axle load determination method further includes: Establishing a first fitting relationship between the height information of the vehicle and the cross-sectional area of the air spring; The cross-sectional area of the air spring is determined according to the first fitting relationship and the height information of the vehicle measured by the sensor.
[0046] Specifically, Figure 2 As shown, in the implementation of the present application, according to the membrane air spring used in the vehicle, the change trend of the effective coefficient of the cross-sectional area in the airbag with the increase or decrease of the height is determined. Through multiple increases and decreases in height, the first fitting relationship between the height information of the vehicle and the cross-sectional area of the air spring is established. Then, when predicting the axle load of the vehicle, the cross-sectional area of the air spring can be determined based on the current height information of the vehicle and the first fitting relationship, and substituted into the axle load prediction model of the vehicle, and the axle load prediction result of the vehicle can be obtained.
[0047] The method of the above embodiment establishes a first fitting relationship between the height information of the vehicle and the cross-sectional area of the air spring by causing the vehicle to rise and fall in height multiple times. Then, when predicting the axle load of the vehicle, the cross-sectional area of the air spring and the axle load prediction result of the vehicle can be accurately determined based on the current vehicle height information and the first fitting relationship.
[0048] In some embodiments, the vehicle axle load determination method further includes: Establishing a second fitting relationship between the height information of the vehicle and the stiffness variation coefficient of the air spring; The stiffness variation coefficient of the air spring is determined according to the second fitting relationship and the height information of the vehicle measured by the sensor.
[0049] Specifically, Figure 3 As shown, in the implementation of this application, the vehicle is unloaded and fully loaded, and the air spring rigidity change trend is verified through multiple height rises and falls, and the second fitting relationship between the vehicle height information and the air spring rigidity change coefficient is established. Then, when predicting the vehicle's axle load, the air spring rigidity change coefficient can be determined based on the current vehicle height information and the second fitting relationship, and substituted into the vehicle's axle load prediction model, and the vehicle's axle load prediction result can be obtained.
[0050] The method of the above embodiment establishes a second fitting relationship between the height information of the vehicle and the stiffness variation coefficient of the air spring. When predicting the axle load of the vehicle, the stiffness variation coefficient of the air spring and the axle load prediction result of the vehicle can be accurately determined based on the current vehicle height information and the second fitting relationship.
[0051] In some embodiments, the vehicle axle load determination method further includes: When the predicted axle load of the vehicle is greater than the preset vehicle load weight, an alarm message is reported.
[0052] Specifically, in the embodiment of the present application, the axle load of the rear axle can be calculated in real time. When the axle load of the rear axle exceeds the vehicle's rated load, it will be sent to the VCU through the CAN line for early warning, and the overload warning light will be reported on the instrument. Optionally, the left and right loads of a single axle can also be calculated separately. If there is a huge difference, it may cause abnormal rollover, which also requires early warning from the VCU and the abnormal load warning light will be reported on the instrument.
[0053] The method of the above embodiment predicts the vehicle axle load through the vehicle axle load prediction model, and reports an alarm message when the vehicle axle load prediction result is greater than the preset vehicle load weight, thereby effectively improving vehicle safety.
[0054] For example, Figure 4 As shown, a method for determining a vehicle axle load is provided in an embodiment of the present application, which is specifically as follows: Based on the vehicle height information and air spring pressure, and taking into account the change in spring stiffness, an axle load prediction model is jointly established: F = α × (h-h0) × β × P Among them, F represents the predicted result of the vehicle axle load; α represents the cross-sectional area of the air spring; h-h0 represents the height change information of the vehicle; β represents the stiffness change coefficient of the air spring; and P represents the pressure of the air spring. Optionally, the loads of the left and right wheels can be calculated separately for the axle load of a single axle. Since the pressures on the left and right sides may be different, after calculating the left and right loads, they are added together as the axle load of the single axle, and the axle load result is more accurate. For the rise and fall of height, the effective coefficient of the cross-sectional area follows different curves and can be converted into αup and αdown, thereby establishing a calculation model for the rise and fall axle load: F = αup × (h-h0) × β × P + f F = αdown × (h-h0) × β × P + f It should be noted that in the present application, a first fitting relationship between the height information of the vehicle and the cross-sectional area of the air spring is established; based on the first fitting relationship and the height information of the vehicle measured by the sensor, the cross-sectional area of the air spring is determined. A second fitting relationship between the height information of the vehicle and the stiffness variation coefficient of the air spring is established; based on the second fitting relationship and the height information of the vehicle measured by the sensor, the stiffness variation coefficient of the air spring is determined. In addition, the present application takes into account the influence of unsprung component factors, adds unsprung component correction items, corrects the influence of the weight of vehicle components on the vehicle axle load, and updates the axle load prediction results, thereby effectively improving the accuracy of the vehicle axle load prediction results. When the vehicle's axle load prediction result is greater than the preset vehicle load weight, an alarm message is reported, which can effectively improve vehicle safety.
