[0051] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and cannot be understood as limiting the embodiments of the present application.

[0052] When loading cargo, the vehicle 100 needs to pay attention to the weight of the cargo at all times, because the weight of the cargo that the vehicle 100 can load is limited to a certain extent, and is the rated load capacity of the vehicle 100. When the weight of the cargo loaded on the vehicle 100 exceeds this limit, the vehicle 100 is in an overloaded state. Driving the vehicle 100 in an overloaded state may easily cause a safety accident of the vehicle 100. For example, the inertia of the vehicle 100 in an overloaded state increases due to the increased mass, thereby lengthening the braking distance and increasing the risk of an accident. Moreover, an overloaded vehicle 100 may also cause the tires to be overloaded and deformed, thereby causing accidents such as tire blowouts, sudden deviation, brake failure, and rollover. In addition, overloading may also affect the steering performance of the vehicle 100, which may easily cause an accident due to loss of steering control.

[0053] Therefore, in order to prevent the vehicle 100 from being overloaded, the on-board weighing system will display the weight of the cargo on the vehicle 100, so as to prompt the overloaded vehicle 100. However, when the on-board weighing system weighs the vehicle 100, due to the weight of the driver or passengers, the weight displayed by the on-board weighing system will deviate from the actual weight of the cargo, so that the user cannot accurately know whether the vehicle 100 is overloaded.

[0054] For the above problems that may be encountered, please refer to Figure 1 and Figure 2 , the present application provides a weighing method, comprising:

[0055] Step 011: Obtain the total load of the vehicle 100 and the current seat load of the seat;

[0056] Among them, the total load of vehicle 100 is the weight of vehicle 100 (the total load of vehicle 100 can be divided into the weight of vehicle 100 without cargo and the weight of vehicle 100 with cargo), and the current seat load of the seat is the weight currently borne by the seat of vehicle 100.

[0057] Specifically, the weighing method of the present application is applied in a vehicle 100, which may be a light truck, a medium truck, or a heavy truck, etc., for carrying cargo, and the vehicle 100 includes a memory 50 and a controller 40, the memory 50 is used to store a computer program, and the controller 40 is used to execute the steps of the weighing method.

[0058] The controller 40 can obtain the total load of the vehicle 100. For example, the controller 40 can control the vehicle 100 to drive to a floor scale, a vehicle weighing instrument, and a weighing sensor, and the floor scale, the vehicle weighing instrument, and the weighing sensor transmit the acquired data to the controller 40, so that the controller 40 obtains the total load of the vehicle 100.

[0059] Furthermore, the controller 40 also needs to obtain the current seat load of the seat of the vehicle 100. For example, a load sensor 20 is provided in the seat, and the controller 40 can obtain data collected by the load sensor 20 by communicating with the load sensor 20, thereby obtaining the current seat load of the seat.

[0060] Step 012: Calculate the cargo load of the vehicle 100 according to the total load and the current seat load;

[0061] Specifically, after obtaining the total load of the vehicle 100 and the current seat load, the controller 40 can calculate the cargo load of the vehicle 100. For example, the controller 40 obtains that the total load of the vehicle 100 is 500 kg and the current seat load is 60 kg, so the controller 40 can calculate that the cargo load of the vehicle 100 is 500 kg-60 kg=540 kg.

[0062] Step 013: In case of cargo overload, a prompt message is issued.

[0063] Specifically, in order to prevent safety accidents, the vehicle 100 has a rated load capacity. When the cargo load of the vehicle 100 exceeds the rated load capacity, the vehicle 100 is deemed to be in an overloaded state. When the controller 40 determines that the cargo load of the vehicle 100 is overloaded, it can control the vehicle 100 to issue a prompt message to remind the user that the vehicle 100 is in an overloaded state.

[0064] For example, the rated load capacity of vehicle 100 is 400 kg, and the load capacity of vehicle 100 after loading the cargo is 420 kg. At this time, the controller 40 determines that the current load capacity of vehicle 100 is greater than the rated load capacity of vehicle 100, so that the controller 40 controls vehicle 100 to issue a prompt message to inform the user that vehicle 100 is currently overloaded.

[0065] In this way, by obtaining the total load weight of the vehicle 100 and the current load weight of the seats of the vehicle 100, and based on the total load weight of the vehicle 100 and the current load weight of the seats, the cargo load weight of the vehicle 100 can be calculated. Compared with directly subtracting the preset seat load weight from the total load weight of the vehicle 100 to obtain the cargo load weight of the vehicle 100, the preset seat load weight has a lower accuracy. In this application, the cargo load weight is determined by obtaining the current seat load in combination with the total load, so that the calculated cargo load weight of the vehicle 100 is more accurate, and when the calculated cargo load is overloaded, a prompt message can be issued to inform the user that the vehicle 100 is overloaded, so that the user can accurately know whether the vehicle 100 is overloaded.

[0066] See also Figure 3 In some embodiments, the vehicle 100 includes a load sensor 20. Step 011: obtaining the total load, including:

[0067] Step 0111: Determine the total load according to the current weighing signal output by the load sensor 20.

[0068] The load sensor 20 may be a device that converts a mass signal into a measurable electrical signal output.

[0069] Specifically, a load sensor 20 is provided on the vehicle 100, and the load sensor 20 can be set at any position of the vehicle 100, such as the load sensor 20 can be set at the front, middle or rear of the vehicle 100. The controller 40 can determine the total load of the vehicle 100 according to the current weighing signal output by the load sensor 20.

[0070] For example, when the vehicle 100 is loaded, the total load of the vehicle 100 changes compared to the state of the vehicle 100 being unloaded, which causes the leaf spring of the load sensor 20 to deform and generate displacement. By measuring the displacement of the spring in the load sensor 20 and converting the displacement of the spring into a measurable voltage output (i.e., the current weighing signal output by the load sensor 20) through the circuit in the load sensor 20, the controller 40 determines the total load according to the change in voltage. For example, when the vehicle 100 is loaded, the spring displacement of the load sensor 20 is 2 cm. The conversion rate of displacement and voltage corresponding to the circuit in the load sensor 20 is 1 V / cm, so that the spring displacement of the load sensor 20 of 2 cm is converted into a voltage of 2 volts. According to the conversion rate of voltage and weight of the load sensor 20 of 250 kg / v, it can be concluded that the total load of the vehicle 100 is 500 kg.

[0071] In this way, the total load is determined by the load sensor 20 outputting the current weighing signal, and the total load of the vehicle 100 after loading can be obtained.

[0072] See also Figure 4 In some embodiments, the vehicle 100 includes a load sensor 20 and a seat pressure sensor 30; the seat pressure sensor 30 is configured to output a seat load signal when the seat load corresponds to the seat load; Step 011: obtaining the current seat load, including:

[0073] Step 0112: When the seat pressure sensor 30 outputs a seat load signal, obtain a current weighing signal of the load sensor 20 and a historical weighing signal before the seat is loaded; and

[0074] Step 0113: Determine the current seat load based on the current weighing signal and the historical weighing signal.

[0075] The seat pressure sensor 30 is a device that can sense pressure signals and convert them into measurable electrical signals. The seat pressure sensor 30 can evenly distribute the contacts that generate pressure signals on the force-bearing surface of each seat, and can generate measurable electrical signals when the seat senses external pressure.

[0076] Specifically, a load sensor 20 and a seat pressure sensor 30 may be provided on the vehicle 100, and both the load sensor 20 and the seat pressure sensor 30 can communicate with the controller 40, and the seat pressure sensor 30 can output a seat load signal when the seat of the vehicle 100 is loaded. When the controller 40 detects that the seat pressure sensor 30 outputs a seat load signal, the controller 40 can determine that there is a load on the seat through the seat load signal. At this time, the controller 40 communicates with the load sensor 20, so that the controller 40 can obtain the current weighing signal of the load sensor 20, and reads the historical weighing information when the seat pressure sensor 30 does not output the seat load information (i.e., the weighing signal generated by the load sensor 20 when there is no load on the seat), so that the controller 40 can determine the current seat load according to the current weighing signal and the historical weighing signal.

[0077] For example, when a user is sitting on the seat of the vehicle 100, the seat pressure sensor 30 can output a seat load signal according to the weight of the user. After receiving the seat load signal, the controller 40 can obtain the weighing signal at this time (such as 430 kg) by communicating with the load sensor 20. The controller 40 can determine the current seat load (such as 60 kg) by reading the weighing signal (such as 370 kg) when there is no user sitting on the seat of the vehicle 100.

[0078] In this way, when the seat of vehicle 100 is loaded, the seat pressure sensor 30 outputs a seat load signal, and at the same time, the current weighing signal of vehicle 100 is obtained through the load sensor 20. According to the current weighing signal, the current total load of vehicle 100 can be determined, and then according to the historical load signal, the historical total load of the seat of vehicle 100 when unloaded can be determined. Finally, the current total load of vehicle 100 is compared with the historical total load, so as to accurately determine the current seat load of vehicle 100.

[0079] See also Figure 5 In some embodiments, the vehicle 100 includes a load sensor 20 and a camera 60; the camera 60 is configured to capture an image of a target object carried by the seat; Step 011: obtaining the current seat load, including:

[0080] Step 0114: Identify the image of the target object to determine the type and size information of the target object;

[0081] Step 0115: Determine the current seat load based on the type and size information.

[0082] Specifically, the vehicle 100 includes a load sensor 20 and a camera 60. The camera 60 is positioned so as to capture an image of a target object of the current seat load. For example, the camera 60 is positioned on the roof in a vertical direction of the seat perpendicular to the ground.

[0083] After the camera 60 takes a picture of the target object carried on the seat, the controller 40 can obtain the image of the target object carried on the seat captured by the camera 60 by communicating with the camera 60, so that the controller 40 can determine the type of the target object by recognizing the image of the target object. For example, the controller 40 can determine the type of the target object, which may be a person, a cat, a dog, or other object, etc., by recognizing the image; and the size information of the target object. For example, by recognizing the image of the target object, when it is determined that the target object is a person, the height and shoulder distance of the target object can be determined; when the target object is an object, the length, width, and height of the object can be determined.

[0084] The controller 40 can determine the current seat load according to the type and size information of the target object.

[0085] For example, when the target object carried on the seat of the vehicle 100 is a person, the controller 40 can estimate the person's weight by identifying the person's body shape data, and thus can use the person's weight as the current seat load; when the target object carried on the seat of the vehicle 100 is an object, the controller 40 can estimate the object's weight by identifying data such as the length, width, height, and material of the object, and thus can use the object's weight as the current seat load.

[0086] In this way, by setting up a camera 60 on the vehicle 100 and taking a picture of the target object on the seat, the image of the target object can be obtained, and after identifying the obtained image, the current seat load can be accurately determined based on the type and size information of the obtained target object.

[0087] Ability to determine current seat load.

[0088] See also Figure 6 , Figure 7 In some embodiments, the vehicle 100 includes a prompter 70. Step 013: issuing a prompt message includes:

[0089] Step 0131: emit a prompt sound, a prompt image and / or a prompt light.

[0090] The prompter 70 includes a display screen 71, a speaker 72 and / or a prompt light 73, and the prompt information includes a prompt picture emitted by the display screen 71, a prompt sound emitted by the speaker 72, and a prompt light emitted by the prompt light 73.

[0091] Specifically, a reminder 70 is provided on the vehicle 100. When an emergency occurs in the vehicle 100 or the vehicle 100 is in an abnormal state, the controller 40 can control the reminder 70 to issue a reminder message.

[0092] For example, when the vehicle 100 is overloaded with cargo, causing the vehicle 100 to be overloaded, the controller 40 can control the display screen 71 to switch the current display screen to a prompt screen, and can display a pre-set prompt text indicating that the vehicle 100 is overloaded on the prompt screen (such as the prompt text can be "The vehicle is overloaded").

[0093] Alternatively, when the vehicle 100 is in an overloaded state, the controller 40 can control the warning light 73 to emit a warning light, such as controlling the warning light 73 to enter a working state from an off state, thereby emitting a red light, a yellow light, or a green light, etc., and the warning light 73 can control the warning light 73 to flash at a preset frequency while emitting a red light (such as the preset frequency can be flashing in a pattern of three long and one short, or two long and two short), thereby reminding the user of the condition of the vehicle 100.

[0094] For another example, when the vehicle 100 is in an overloaded state, the controller 40 can control the speaker 72 to emit a prompt sound, such as controlling the speaker 72 to emit a buzzing sound, or emit a preset prompt sound of "the vehicle 100 is in an overloaded state".

[0095] Optionally, when the vehicle 100 is in an abnormal state, the controller 40 can simultaneously control the display screen 71 to display a prompt image, the speaker 72 to emit a prompt sound, and the prompt light 73 to emit a prompt light.

[0096] Optionally, the prompt switch button 713 on the display screen 71 of the vehicle 100 can be used to turn on or off the prompt sound emitted by the speaker 72 and the prompt light emitted by the prompt light 73, thereby satisfying the settings of prompt information for different users.

[0097] In this way, by sending a prompt picture through the display screen 71 of the vehicle 100, the speaker 72 sending a prompt sound and / or the prompt light 73 sending a prompt light, the probability of the user discovering the prompt information can be increased, thereby ensuring the reliability of reminding the customer to understand that the vehicle 100 is overloaded.

[0098] See also Figure 8 and Fig. 9In some embodiments, the vehicle 100 includes a display screen 71, and the weighing method further includes:

[0099] Step 014: According to the cargo load, control the load display information of the display screen 71, the load display information includes the load mass and the preset load threshold.

[0100] Specifically, when the vehicle 100 has completed loading the cargo, the controller 40 displays the load information of the vehicle 100 on the display screen 71 of the vehicle 100. The user can understand the load information of the vehicle 100 through the display screen 71. The load information includes the load mass and a preset load threshold.

[0101] For example, the weight of the cargo is 300 kg. After the vehicle 100 has completed loading the cargo, the controller 40 can control the display screen 71 to display that the load weight of the vehicle 100 is 400 kg, and display the load weight threshold of the vehicle 100 as 500 kg on the display screen 71.

[0102] Optionally, the load display information can be displayed on the display screen 71 via a bar graph, and a load scale is marked on the bar graph. The full scale on the bar graph represents the maximum cargo load of the vehicle 100, and a load threshold is set under the maximum cargo load. The user can adjust the load threshold, and the current load mass can be displayed on the bar graph.

[0103] In this way, by displaying the load information of the vehicle 100 on the display screen 71, the user can always understand the load status of the vehicle 100 and determine whether it is overloaded so as to make corresponding adjustments.

[0104] See also Fig.10 and Fig.11 In some embodiments, the weighing method further comprises:

[0105] Step 015: Obtain input information of the preset load input box;

[0106] Step 016: Set a preset load threshold based on the input information.

[0107] Specifically, the controller 40 is able to obtain input information of a preset load input box, and set a preset load threshold of the vehicle 100 according to the input information input by the user, and determine that the vehicle 100 is overloaded when the cargo load is greater than the preset load threshold.

[0108] For example, the user can enter the preset load threshold of the vehicle 100 in the preset load input box displayed on the display screen 71 of the vehicle 100 (the preset load threshold may be 500 kg, 1000 kg, etc.); or the user can enter the preset load threshold of the vehicle 100 in the preset load input box on an electronic device that is communicatively connected to the display screen 71 of the vehicle 100 (such as the electronic device that is communicatively connected to the display screen 71 of the vehicle 100 may be a smart phone, tablet computer, etc.). When the preset load threshold is 500 kg, the cargo load of the vehicle 100 displayed on the display screen 71 is 550 kg, thereby determining that the vehicle 100 is overloaded.

[0109] In this way, by obtaining the input information in the preset load input box, the preset load threshold of the vehicle 100 can be modified, so that the user can freely plan the total load of the vehicle 100, which can improve the user experience.

[0110] See also Fig.12 and Fig.13 In some embodiments, the weighing method further comprises:

[0111] Step 017: Obtain a calibration instruction, and set the initial cargo load to a preset initial load according to the calibration instruction.

[0112] Specifically, in order to improve the accuracy of obtaining the total load of the vehicle 100, the preset initial load of the vehicle 100 needs to be calibrated. The controller 40 obtains the calibration instruction of the vehicle 100 and sets the initial cargo load to the preset initial load according to the calibration instruction.

[0113] For example, when the controller 40 detects that there is a deviation in the initial load of the vehicle 100 (such as when the vehicle 100 is not carrying cargo, the load of the vehicle 100 displayed on the display screen 71 is not 0), the user clicks the calibration button 711 on the display screen 71 so that the controller 40 can obtain the calibration instruction, thereby modifying the value of the total load of the vehicle 100 displayed on the display screen 71 to zero; or, when the user is inside the vehicle 100, by clicking the calibration button 711, the controller 40 can obtain the calibration instruction, thereby modifying the value of the total load of the vehicle 100 displayed on the display screen 71 to the user's weight.

[0114] In this way, by obtaining the calibration instruction to calibrate the initial cargo load, the total load of the vehicle 100 can be accurately displayed, avoiding the cargo load displayed by the vehicle 100 being inconsistent with the actual cargo load of the vehicle 100, thereby causing the vehicle 100 to be overloaded.

[0115] See also Fig.14 and Fig.15 In some embodiments, the weighing method further comprises:

[0116] Step 018: Get the save instruction and save the current cargo load according to the save instruction.

[0117] Specifically, the controller 40 can obtain a save instruction and save the current cargo load according to the save instruction.

[0118] For example, a save button 712 is provided on the display screen 71 of the vehicle 100. The user clicks the save button 712 to enable the controller 40 to obtain the save instruction, thereby displaying the current cargo load of the vehicle 100 on the display screen 71. By clicking the save button 712 multiple times, the cargo load records of the vehicle 100 in different time periods can be displayed on the display screen 71, such as record 1 that the cargo load of the vehicle 100 is 220 kg, and record 2 that the cargo load of the vehicle 100 is 300 kg.

[0119] In this way, by obtaining the saving instruction, the weight of the vehicle 100 when carrying cargo can be monitored, so that the user can clearly understand the changes in the cargo load.

[0127] The weighing device 10 further includes a fourth acquisition module 18, which is used to acquire a save instruction and save the current cargo weight according to the save instruction.
