Description

Background Art

[0002] During the actual operation of port AGVs (Automated Guided Vehicles), we found that the vehicle's motion control strategy is highly related to the load. When the vehicle's load capacity changes, it is necessary to adjust the parameters of the electric control system to more effectively help the vehicle save electricity and adjust the speed. And in order to explore the structural fatigue of the vehicle under long-term motion conditions, it is necessary to monitor the load capacity of the AGV to study the vehicle's load spectrum. Currently, there is no effective way to obtain the weight of the containers unloaded from the spreader such as the quay crane to the AGV from the terminal dispatching system. The uncertain driving path of the AGV also makes it impossible to set a weighbridge on its "necessary route", nor can it transmit data such as impact loads in real time.

[0003] In the current use of AGVs, due to the inability to obtain real-time information such as the vehicle's load capacity, impact conditions, and whether there is uneven loading, it is impossible to timely allocate devices such as the vehicle body suspension and implement compensation for dangerous situations such as overloading and uneven loading of the vehicle.

[0004] Therefore, the present invention provides a vehicle attitude balance system, method, device, and storage medium applicable to the horizontal battery swapping mode. Summary of the Invention

[0005] Aiming at the problems in the prior art, the purpose of the present invention is to provide a vehicle attitude balance system, method, device, and storage medium, which overcome the difficulties of the prior art, can obtain real-time bearing weight data of each part of the vehicle, know whether the vehicle body is overloaded or unevenly loaded, timely allocate devices such as the vehicle body suspension, and implement compensation for the vehicle attitude balance.

[0006] An embodiment of the present invention provides a vehicle attitude balance system, including:

[0007] Several groups of balance suspension components, each group of the balance suspension components including:

[0008] A balance suspension support, connected to the lower part of the vehicle frame;

[0009] A balance beam, each balance beam is arranged below the corresponding balance suspension support, and both ends of the balance beam are respectively connected to a wheel; and

[0010] A pin-type gravity sensor, pin-connected to the balance suspension support and the balance beam, the pin-type gravity sensor detects in real time the gravity transmitted through the balance suspension support to obtain gravity data, and at least based on the position of the pin-type gravity sensor on the vehicle frame and the corresponding gravity data, the vehicle frame is horizontally adjusted (so that the plane where the vehicle frame 7 is located fits the horizontal plane).

[0011] Preferably, the balance suspension assemblies are arranged in pairs in the vehicle body width direction below the frame.

[0012] Preferably, the balance suspension assembly is arranged between a pair of axles, and the extension direction of the kingpin type gravity sensor is parallel to the extension direction of the axle.

[0013] Preferably, it further includes

[0014] a plurality of axles, with both ends of the axles respectively connected to the wheels;

[0015] a plurality of transverse tie rods, with both ends of the transverse tie rods respectively hinged to the bearings of the wheels through connecting arms;

[0016] a plurality of thrust rods, with both ends of the thrust rods respectively connected to the balance suspension support and the middle parts of the axles on both sides of the balance suspension support.

[0017] Preferably, it further includes an active suspension assembly and a processing unit;

[0018] The processing unit is respectively connected to the kingpin type gravity sensor and the active suspension assembly. The processing unit receives the gravity data of the kingpin type gravity sensor, obtains the attitude compensation data of the frame according to the position of the kingpin type gravity sensor on the frame and the corresponding gravity data, and sends the attitude compensation data to the active suspension assembly according to the attitude compensation data. The active suspension distributed below the frame independently compensates in the vertical direction to keep the frame in a horizontal state.

[0019] Preferably, the active suspension assembly includes a plurality of active suspensions, and the active suspensions are respectively located above or on the sides of the balance suspension support.

[0020] Preferably, a mapping relation table is pre-stored in the processing unit. The mapping relation table is provided with the mapping relation between the gravity data group and the attitude compensation data group. The gravity data group is a gravity data sequence sorted according to the preset positions of the kingpin type gravity sensors, and the attitude compensation data group is an attitude compensation data sequence sorted according to the preset positions of the active suspensions;

[0021] The active suspension drives the suspension to lift according to the corresponding attitude compensation data in the attitude compensation data sequence, and the attitude compensation data is the lifting distance in the vertical direction.

[0022] Preferably, the data collected by the kingpin type gravity sensor in the vehicle attitude balance system of the present invention can be used to adjust the height of the chassis system, prevent other systems of the vehicle from being too close to the ground and being touched by protruding objects on the ground when overloaded; it can also prevent the bumper from colliding with the ground when the slope is uneven during climbing. The calculation process of obtaining the deformation amount Lm of the frame ground clearance is as follows:

[0023] The ground clearance of the vehicle frame in the natural state is \(L0 = H0 + R0 - 200\);

[0024] The ground clearance of the vehicle frame under load is \(L1 = H1 + R1 - 200\);

[0025] Where, \(H0\) is the height of the suspension in the natural state; \(H1\) is the height of the suspension after deformation under load; \(R0\) is the height of the suspension in the natural state; \(R1\) is the height of the suspension after deformation under load; \(L0\) is the ground clearance of the vehicle frame in the natural state; \(L1\) is the ground clearance of the vehicle frame under load.

[0026] The relationship between the vertical deformation of the suspension and the load of the rubber suspension, and its inverse function is:

[0027] The vertical deformation of the suspension \(h = 4E - 06*f3 - 0.0024*f2 + 0.6*f + 0.8\), where \(E\) is the load of the rubber suspension and \(h\) is the vertical deformation of the suspension;

[0028] In this embodiment, the inverse function of the relationship between the vertical deflection of the tire and the vertical load of the tire is:

[0029] The vertical deflection of the tire \(r = -0.0008f2 + 0.5f + 0.5\), where \(r\) is the vertical deflection of the tire and \(f\) is the vertical load of the tire;

[0030] When the reading of the kingpin gravity sensor is \(M\), \(fm = Mg\), where \(M\) is the vehicle load mass reading after the kingpin gravity sensor is installed and zeroed, and \(g\) is the gravitational constant.

[0031] \(H0 - H1 = hm = 4E - 06*fm3 - 0.0024*fm2 + 0.6*fm + 0.8\);

[0032] \(R0 - R1 = rm = -0.0008fm2 + 0.5fm + 0.5\);

[0033] The deformation amount of the ground clearance of the vehicle frame is \(Lm\):

[0034] \(Lm = L0 - L1 = hm + rm = 4E - 06*fm3 - 0.0016*fm2 + 1.1*fm + 1.3\).

[0035] When the vehicle is unevenly loaded, the four suspensions are not at the same height. The vehicle adjusts the deformation amount \(Lm\) of the ground clearance of the vehicle frame through the system control of the lifting cylinder, so that the deformation amounts of the ground clearances of the four vehicle frames are approximately at the same height, ensuring that the vehicle load plane is in a horizontal state.

[0036] The embodiment of the present invention also provides a vehicle attitude balance method, which adopts the above vehicle attitude balance system, and includes the following steps:

[0037] The pin - type gravity sensor pins the balance suspension support and the balance beam, and detects in real time the gravity transmitted through the balance suspension support to obtain gravity data.

[0073] Figure 1 It is the front view of the vehicle attitude balance system of the present invention. Figure 2 It is the top view of the vehicle attitude balance system of the present invention applied under the vehicle frame. Figure 3 is Figure 2 the sectional view taken along the line A-A in Figures 1 to 3 As shown, the vehicle attitude balance system of the present invention includes: several groups of balance suspension components. Each group of balance suspension components includes: a balance suspension support 8, a balance beam 4, and a pin-type gravity sensor 5. The balance suspension support 8 is connected below the vehicle frame 7. Each balance beam 4 is disposed below the corresponding balance suspension support 8, and both ends of the balance beam 4 are respectively connected to a wheel 1. The pin-type gravity sensor 5 is pinned to connect the balance suspension support 8 and the balance beam 4. The pin-type gravity sensor 5 detects in real time the gravity transmitted through the balance suspension support 8 to obtain gravity data, and based at least on the position of the pin-type gravity sensor 5 on the vehicle frame 7 and the corresponding gravity data, the vehicle frame 7 is horizontally adjusted (so that the plane where the vehicle frame 7 is located fits the horizontal plane). In this embodiment, the pin-type gravity sensor 5 is provided with a central hole, and a double-shear type resistance strain gauge is pasted in the central hole. When the pin-type gravity sensor 5 is subjected to extrusion forces in various directions, the double-shear type resistance strain gauge pasted in the central hole undergoes strain under the action of the force and is converted into an electrical signal for output. The pin-type gravity sensor 5 in the present invention can not only act as a pin, but also convert the strain into an electrical signal through the signal wire at the tail to help better control the vehicle.

[0074] The balance suspension support 8 in the present invention can be a rubber balance suspension. In the vehicle chassis assembly of the present invention, when the vehicle is in motion, the axle 3 rotates around the rubber balance suspension pin according to the road conditions. The pin bears the forces from the upper and lower halves of the suspension, and the magnitude and direction of the pressure are constantly changing as the vehicle moves. Therefore, a high-precision pin-type gravity sensor is provided at the rubber suspension balance shaft. On the one hand, it acts as the original balance shaft, and on the other hand, it records the load condition at this position in real time. By setting four pin-type gravity sensors on two groups of suspensions, the vehicle load, impact conditions, and whether there is uneven loading can be clearly known. The collected weights are studied and the load spectrum data is processed using the rain flow counting method to refine the dynamic load spectrum, which effectively helps to analyze the fatigue condition of the vehicle structure and estimate the fatigue life.

[0075] In a preferred embodiment, the high-precision pin-type gravity sensor replaces the balance shaft of the existing balance suspension assembly and is symmetric about the vehicle frame center. Any change in weight in the front-rear or left-right direction of the vehicle will be sensed by the pin-type gravity sensor, helping the vehicle to cope with abnormal phenomena such as uneven loading or uneven load distribution.

[0076] In a preferred embodiment, after analyzing the overall system structure of the vehicle, the present invention also proposes a weighing system for the vehicle balance suspension.

[0077] In a preferred embodiment, the balance suspension assemblies are arranged in pairs along the width direction of the vehicle body below the vehicle frame 7 for more accurate attitude compensation in a targeted manner, but not limited thereto.

[0078] In a preferred embodiment, the balance suspension assembly is arranged between a pair of axles 3, and the extension direction of the pin-type gravity sensor 5 is parallel to the extension direction of the axle 3, but not limited thereto.

[0079] In a preferred embodiment, it further includes

[0080] Several axles 3, with both ends of the axle 3 respectively connected to the wheels 1.

[0081] Several cross tie rods 2, with both ends of the cross tie rod 2 respectively hinged to the bearings of the wheels 1 through connecting arms.

[0082] Several thrust rods 6, with both ends of the thrust rod 6 respectively connected to the balance suspension support 8 and the middle parts of the axles 3 on both sides of the balance suspension support 8, but not limited thereto.

[0083] In a preferred embodiment, it further includes an active suspension assembly (not shown in the figure) and a processing unit. The processing unit is respectively connected to the kingpin gravity sensor 5 and the active suspension assembly. The processing unit receives the gravity data of the kingpin gravity sensor 5, obtains the attitude compensation data of the vehicle frame 7 based on the position of the kingpin gravity sensor 5 on the vehicle frame 7 and the corresponding gravity data, and sends the attitude compensation data to the active suspension assembly according to the attitude compensation data. The active suspensions distributed under the vehicle frame 7 independently perform vertical compensation to keep the vehicle frame 7 in a horizontal state. By inputting the gravity data obtained by the kingpin gravity sensor 5 into the processing unit, the preset attitude compensation data can be accurately obtained. The active suspension assembly uses the attitude compensation data to perform actual attitude compensation to ensure the overall horizontal of the vehicle frame 7. The active suspension can be an independent air suspension or an oil cylinder in the vertical direction, but is not limited thereto.

[0084] In a preferred embodiment, the active suspension assembly includes a plurality of active suspensions, and the active suspensions are respectively located above or on the side of the balance suspension support 8.

[0085] In a preferred embodiment, a mapping relation table is pre-stored in the processing unit. The mapping relation table is provided with the mapping relation between the gravity data group and the attitude compensation data group. The gravity data group is a sequence of gravity data sorted according to the preset positions of the kingpin gravity sensors 5, and the attitude compensation data group is a sequence of attitude compensation data sorted according to the preset positions of the active suspensions. The active suspension drives the suspension to rise and fall according to the corresponding attitude compensation data in the attitude compensation data sequence. The attitude compensation data is the up and down distance in the vertical direction, but is not limited thereto.

[0086] Figure 4 It is a schematic diagram of the vehicle attitude balance system of the present invention obtaining the deformation amount of the vehicle frame ground clearance. Figure 5 It is a schematic diagram of the functional relationship between the vertical deformation amount of the suspension and the rubber suspension load in the vehicle attitude balance system of the present invention. Figure 4 and 5 As shown in and, in a variation, the data collected by the kingpin gravity sensor of the vehicle attitude balance system of the present invention can be used to adjust the height of the chassis system to prevent other systems of the vehicle from being too close to the ground and being hit by protruding objects on the ground when the vehicle is heavily loaded; it can also prevent the bumper from colliding with the ground due to uneven slopes when climbing. The calculation process for obtaining the deformation amount Lm of the vehicle frame ground clearance is as follows:

[0087] The ground clearance of the vehicle frame in the natural state L0 = H0 + R0 - 200;

[0088] The ground clearance of the vehicle frame under load L1 = H1 + R1 - 200;

[0089] Among them, H0 is the natural state height of the suspension; H1 is the height after the suspension is deformed under load; R0 is the natural state height of the suspension; R1 is the height after the suspension is deformed under load; L0 is the ground clearance height of the frame in the natural state; L1 is the ground clearance height of the frame under load.

[0090] Figure 5 It is the relationship between the vertical deformation of the suspension (x-axis) and the rubber suspension load (y-axis), and its inverse function is:

[0091] The vertical deformation of the suspension h = 4E-06*f3 - 0.0024*f2 + 0.6*f + 0.8, where E is the rubber suspension load and h is the vertical deformation of the suspension;

[0092] In this embodiment, the inverse function of the relationship between the vertical deflection of the tire and the vertical load of the tire is:

[0093] The vertical deflection of the tire r = -0.0008f2 + 0.5f + 0.5, where r is the vertical deflection of the tire and f is the vertical load of the tire;

[0094] When the reading of the kingpin gravity sensor is M, fm = Mg, where M is the vehicle load mass reading after the kingpin gravity sensor is installed and zeroed, and g is the gravitational constant.

[0095] H0 - H1 = hm = 4E-06*fm3 - 0.0024*fm2 + 0.6*fm + 0.8;

[0096] R0 - R1 = rm = -0.0008fm2 + 0.5fm + 0.5;

[0097] The deformation amount of the ground clearance height of the frame is Lm:

[0098] Lm = L0 - L1 = hm + rm = 4E-06*fm3 - 0.0016*fm2 + 1.1*fm + 1.3.

[0099] When the vehicle is unevenly loaded, the four suspensions are not at the same height. The vehicle adjusts the deformation amount Lm of the ground clearance height of the frame through the system control of the lifting cylinder, so that the four deformation amounts of the ground clearance height are roughly at the same height, ensuring that the vehicle load plane is in a horizontal state.

[0100] Since the present invention has the above technical features, it has at least the following technical advantages:

[0101] 1. There is no need to additionally set a weighing device outside the vehicle body and other infrastructure. It is directly integrated into the vehicle body. On the one hand, it acts as a balance kingpin, and on the other hand, it records the load weight, helps the electronic control system adjust parameters and control speed, making the vehicle more energy-efficient and efficient.

[0102] 2. A pin - type high - precision gravity sensor is set at the balance pin shaft, which can record the load condition in real time for fatigue life estimation and compilation of fatigue test load spectra.

[0103] 3. Four pin - type gravity sensors are set on two groups of balance rubber suspensions, which can clearly know the vehicle's off - loading condition.

[0104] 4. The pin - type gravity sensor has a compact structure, a simple geometric shape. The hollow cross - section has strong anti - torsion and anti - bending capabilities, high dimensional and geometric tolerances, and is easy to assemble with the suspension load - bearing components and convenient to use.

[0105] Figure 6 is the flowchart of the vehicle attitude balance method of the present invention. As Figure 6 shown, the vehicle attitude balance method of the present invention adopts the above - mentioned vehicle attitude balance system, including the following steps:

[0106] S110. The pin - type gravity sensor 5 is pinned to the balance suspension support 8 and the balance beam 4 to detect the gravity transmitted through the balance suspension support 8 in real time and obtain gravity data. And

[0107] S120. At least based on the position of the pin - type gravity sensor 5 on the vehicle frame 7 and the corresponding gravity data, the vehicle frame 7 is horizontally adjusted.

[0108] The vehicle attitude balance method of the present invention can obtain the bearing weight data of each part of the vehicle in real time, know whether the vehicle body is overloaded or off - loaded, and timely allocate devices such as the vehicle body suspension to implement compensation for the vehicle attitude balance.

[0109] The embodiment of the present invention also provides a vehicle attitude balance device, including a processor and a memory, in which the executable instructions of the processor are stored. Among them, the processor is configured to execute the steps of the vehicle attitude balance method by executing the executable instructions.

[0110] As shown above, the vehicle attitude balance system of the present invention can obtain the bearing weight data of each part of the vehicle in real time, know whether the vehicle body is overloaded or off - loaded, and timely allocate devices such as the vehicle body suspension to implement compensation for the vehicle attitude balance.
