[0007] Based on the height change data, the weight change data of each wheel of the vehicle is calculated using a preset weight formula, and differential compensation is performed on each wheel according to the weight change data of each wheel to obtain the final weight data of the vehicle.

[0008] The system determines whether the final weight data is greater than the preset load standard data.

[0015] If the vehicle height change data contains abnormal data, the abnormal data is filtered out, and the vehicle height change data is received again until all vehicle height change data is in a normal state.

[0016] According to one embodiment of this application, the step of performing differential compensation on each wheel based on the weight change data of each wheel to obtain the final weight data of the vehicle includes:

[0017] The average weight change of all wheels is calculated based on the weight change data of each wheel.

[0018] Using the elastic coefficient of each wheel, the deviation between the weight change data of each wheel and the average weight change data of all wheels is calculated based on the height change data. Based on the deviation, differential compensation is performed on the weight change data of each wheel to obtain the final weight data of the vehicle.

[0019] According to one embodiment of this application, after determining whether the final weight data is greater than the preset load-bearing standard data, the method further includes:

[0020] If the final weight data is less than or equal to the preset load standard data, it is determined that the vehicle is not overloaded, the load information of the vehicle is obtained, and the final weight data and the load information are sent to the vehicle display unit for display.

An overload alarm signal is generated based on the overload information, and the final weight data, overload information, and overload alarm signal are sent to the vehicle display unit for display to remind the user of overload. This solves the problem in related technologies where the lack of an effective load detection alarm method makes it impossible to accurately determine the vehicle's load status.

[0048] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0049] The following description, with reference to the accompanying drawings, outlines an overload warning method, device, vehicle, and storage medium for vehicles according to embodiments of this application. Addressing the problem mentioned in the background art where the lack of an effective load detection alarm method prevents accurate assessment of vehicle load conditions, this application provides an overload warning method for vehicles. In this method, based on vehicle height change data, the weight change data of each wheel is calculated using a preset weight formula. Differential compensation is applied to each wheel to obtain the final weight data of the vehicle. When the final weight data exceeds a preset load standard data, the vehicle is determined to be overloaded, obtaining overload information. An overload alarm signal is generated based on the overload information, and the final weight data, overload information, and overload alarm signal are sent to an on-board display unit for display, thus providing an overload warning to the user. This solves the problem in related technologies where the lack of an effective load detection alarm method prevents accurate assessment of vehicle load conditions. The overload warning function helps users understand the overall status of the vehicle at any time, thereby accurately assessing the vehicle's load conditions and avoiding unnecessary violations.

[0050] Specifically, Figure 1 This is a flowchart illustrating a method for alerting a vehicle to overload, as provided in an embodiment of this application.

[0051] like Figure 1 As shown, the overload warning method for this vehicle includes the following steps:

[0052] In step S101, the vehicle's height change data is received.

[0053] According to one embodiment of this application, receiving vehicle height change data includes: identifying the vehicle's motion state; when the vehicle is stationary, receiving first height change data of the vehicle chassis from the ground; and when the vehicle is in motion, receiving second height change data of the vehicle chassis from the ground.

[0054] Specifically, such as Figure 2 As shown in this embodiment, firstly, the vehicle's height change data is acquired through a height sensor. This mainly includes the following: when the vehicle is stationary, for example, when a user gets in or out of the vehicle, or when cargo is added or removed from the cargo box, the vehicle's height will change. In this case, the height sensor can acquire the first height change data of the vehicle chassis relative to the ground. When the vehicle is in motion, for example, when the vehicle encounters different road conditions (such as bumps, slopes, etc.) during driving, the vehicle's height will also change. In this case, the height sensor can acquire the second height change data of the vehicle chassis relative to the ground. Then, the first and second height change data are converted into electrical signals and sent to the PCDM (Partial chassis domain mode), hereinafter referred to as PCDM. Secondly, after receiving the first and second height change data of the vehicle, the PCDM outputs a signal indicating the overall vehicle height change.

[0055] The height sensor is usually installed on the vehicle's suspension system. It can be a sensor located near each wheel or installed in other locations on the vehicle chassis. The height sensor can monitor the changes in the height of the vehicle chassis relative to the ground in real time.

[0056] According to one embodiment of this application, after receiving vehicle height change data, the method further includes: identifying whether there is abnormal data in the vehicle height change data; if there is abnormal data in the vehicle height change data, filtering the abnormal data and continuing to receive vehicle height change data until all vehicle height change data are in a normal state.

[0057] Specifically, in this embodiment, after receiving the vehicle height change data, the PCDM also needs to identify the vehicle height change data and verify it. If there is abnormal data, it is filtered out and the PCDM continues to receive vehicle height change data until all vehicle height change data are in a normal state, thereby ensuring the accuracy of the calculation results.

[0058] In step S102, based on the height change data, the weight change data of each wheel of the vehicle is calculated using a preset weight formula, and differential compensation is performed on each wheel according to the weight change data of each wheel to obtain the final weight data of the vehicle.

[0059] According to one embodiment of this application, differential compensation is performed on each wheel based on the weight change data of each wheel to obtain the final weight data of the vehicle, including: calculating the average weight change data of all wheels based on the weight change data of each wheel; using the elastic coefficient of each wheel, calculating the deviation between the weight change data of each wheel and the average weight change data of all wheels based on the height change data, and performing differential compensation on the weight change data of each wheel based on the deviation to obtain the final weight data of the vehicle.

[0060] The preset weight formula can be set by those skilled in the art based on the actual control logic, and is not specifically limited here.

[0061] Specifically, in this embodiment, based on the height change data of the vehicle chassis relative to the ground obtained above, firstly, the weight change data of each wheel of the vehicle is calculated using a preset weight formula based on the spring coefficient and the height change data of the vehicle chassis relative to the ground. The preset weight formula can be expressed as:

[0062] W = K × δH;

[0063] Where W is the weight change data for each wheel, δH is the height change data for each wheel, and K is the spring constant.

[0064] Secondly, in order to eliminate errors caused by uneven road surfaces or other factors and ensure the accuracy of the weight change data for each wheel, PCDM needs to perform differential compensation for each wheel based on the deviation between the weight change data of each wheel and the average weight change data of all wheels.

[0065] Specifically, the height change data of the vehicle's four wheels can be represented as δH1, δH2, δH3, and δH4, respectively. Using a preset weight formula, the elastic coefficient of each wheel and the height change data of each wheel are used to calculate the corresponding weight change data of each wheel, represented as W1, W2, W3, and W4, respectively. Based on the height change data, the deviation between the weight change data of each wheel and the average weight change data of all wheels is calculated, and differential compensation is performed on the weight change data of each wheel based on the deviation. Then, the compensated weight change data of each wheel are summed to obtain the final weight data of the vehicle, which is recorded and transmitted to the IHU (In-Vehicle Human Unit) via CAN (Controller Area Network) signal. The IHU displays the received final weight data of the vehicle on the in-vehicle display screen in real time.

[0066] For example, when the vehicle is stationary, such as when a user is loading goods in the cargo box, the height sensor detects the first height change data of the vehicle chassis relative to the ground and transmits the first height change data to the PCDM. The PCDM calculates the weight change data of each wheel of the vehicle based on the first height change data using a preset weight formula. After calculating the deviation between the weight change data of each wheel and the average weight change data of all wheels, it performs differential compensation on the weight change data of each wheel based on the deviation. The compensated weight change data of each wheel are summed to obtain the final weight data of the vehicle.

[0067] When the vehicle is in motion, such as when it encounters bumps or slopes, the height sensor continues to monitor the second height change data of the vehicle chassis relative to the ground and transmits this data to the PCDM in real time. The PCDM then uses a preset weight formula to calculate the weight change data of each wheel based on the latest second height change data. After calculating the deviation between the weight change data of each wheel and the average weight change data of all wheels, the PCDM performs differential compensation on the weight change data of each wheel based on the deviation. The compensated weight change data of each wheel are then summed to obtain the final weight data of the vehicle, ensuring the accuracy of the vehicle overload judgment.

[0068] In step S103, it is determined whether the final weight data is greater than the preset load standard data. If the final weight data is greater than the preset load standard data, the vehicle is determined to be overloaded, the overload information of the vehicle is obtained, an overload alarm signal is generated based on the overload information, and the final weight data, overload information and overload alarm signal are sent to the vehicle display unit for display to remind the user of overload.

[0069] According to one embodiment of this application, after determining whether the final weight data is greater than the preset load standard data, the method further includes: if the final weight data is less than or equal to the preset load standard data, then determining that the vehicle is not overloaded, obtaining the vehicle's load information, and sending the final weight data and load information to the vehicle display unit for display.

[0070] The preset load-bearing standard data can be set by those skilled in the art based on the actual control logic, or it can be obtained through a limited number of computer simulations. Overload information and load-bearing information may include the number of vehicle passengers or the amount of cargo loaded in the vehicle, etc., and are not specifically limited here.

[0071] Specifically, such as Figure 2 As shown in this embodiment, based on the final weight data of the vehicle obtained above, it is necessary to further compare the final weight data with the preset load standard data. If the final weight data is greater than the preset load standard data, the vehicle is determined to be overloaded, the overload information of the vehicle is obtained, and an overload alarm signal is generated. Then, the final weight data, overload information, and overload alarm signal are sent to the vehicle display unit, such as the IHU. After receiving the final weight data, overload information, and overload alarm signal of the vehicle, the IHU can display a "vehicle overloaded" warning message on the screen or remind the user of overload through an audible alarm. If the final weight data is less than or equal to the preset load standard data, the vehicle is determined not to be overloaded. At this time, the load information of the vehicle is obtained, and the final weight data and load information are sent to the IHU for display.

[0072] In summary, based on the above-described method for reminding vehicles of overload, the embodiments of this application can achieve the following beneficial effects:

[0073] (1) Improved safety: By monitoring the vehicle’s height changes in real time through height sensors, the vehicle’s weight changes can be detected in a timely manner, and the vehicle can be accurately judged as overloaded. If the vehicle is overloaded, visual and audible alarms can be issued through the vehicle display unit to remind the driver to take timely measures to avoid safety accidents caused by overloading.

[0074] (2) Extend vehicle service life. Through real-time monitoring and reminders, it can effectively prevent vehicles from being overloaded for a long time, reduce excessive wear on vehicle suspension system, tires, braking system and other components, thereby reducing maintenance and repair costs, extending vehicle service life, and storing vehicle usage data to avoid unnecessary risks. Through data analysis, it can support the iterative improvement of the whole vehicle.

[0075] (3) Enhance user experience. The vehicle display unit can display the vehicle's current weight and load in real time, helping users to better manage the vehicle's load. At the same time, through visual and auditory reminders, it ensures that users can quickly notice the overload situation and take appropriate measures in a timely manner.

[0076] The vehicle overload warning method according to embodiments of this application calculates the weight change data of each wheel of the vehicle based on the vehicle's height change data using a preset weight formula, and performs differential compensation on each wheel to obtain the vehicle's final weight data. When the final weight data exceeds a preset load standard data, the vehicle is determined to be overloaded, and overload information is obtained. An overload alarm signal is generated based on the overload information, and the final weight data, overload information, and overload alarm signal are sent to the vehicle display unit for display to remind the user of overload. This solves the problem in related technologies where the lack of an effective load detection alarm method makes it impossible to accurately determine the vehicle's load status. Through the overload warning function, users can understand the overall status of the vehicle at any time, thereby accurately judging the vehicle's load status and avoiding unnecessary violations.

[0077] Next, referring to the accompanying drawings, an overload warning device for vehicles proposed according to an embodiment of this application is described.

[0078] Figure 3 This is a block diagram of an overload warning device for a vehicle according to an embodiment of this application.

[0079] like Figure 3 As shown, the overload warning device 10 for the vehicle includes: a receiving module 100, a calculation module 200, and a warning module 300.

[0081] The calculation module 200 is used to calculate the weight change data of each wheel of the vehicle based on the height change data and a preset weight formula, and to perform differential compensation on each wheel according to the weight change data of each wheel to obtain the final weight data of the vehicle.

[0082] The reminder module 300 is used to determine whether the final weight data is greater than the preset load standard data. If the final weight data is greater than the preset load standard data, the vehicle is determined to be overloaded, the overload information of the vehicle is obtained, an overload alarm signal is generated based on the overload information, and the final weight data, overload information and overload alarm signal are sent to the vehicle display unit for display to remind the user of overload.

[0083] According to one embodiment of this application, the receiving module 100 is specifically used for:

[0085] When the vehicle is stationary, receive the first height change data of the vehicle chassis from the ground.

[0086] When the vehicle is in motion, it receives data on the second height change of the vehicle chassis from the ground.

[0087] According to one embodiment of this application, after receiving vehicle height change data, the receiving module 100 is further configured to:

[0088] Identify any anomalies in the vehicle's height change data;

[0089] If there are abnormal data in the vehicle height change data, the abnormal data will be filtered out, and the system will continue to receive vehicle height change data until all vehicle height change data are in a normal state.

[0090] According to one embodiment of this application, the calculation module 200 is specifically used for:

[0091] The average weight change of all wheels is calculated based on the weight change data of each wheel.

[0092] Using the elastic coefficient of each wheel, the deviation between the weight change data of each wheel and the average weight change data of all wheels is calculated based on the height change data. Then, differential compensation is performed on the weight change data of each wheel based on the deviation to obtain the final weight data of the vehicle.

[0093] According to one embodiment of this application, after determining whether the final weight data is greater than the preset load standard data, the reminder module 300 is further configured to:

[0094] If the final weight data is less than or equal to the preset load standard data, it is determined that the vehicle is not overloaded, the vehicle's load information is obtained, and the final weight data and load information are sent to the vehicle display unit for display.

[0095] The vehicle overload warning device according to an embodiment of this application calculates the weight change data of each wheel of the vehicle based on the vehicle's height change data using a preset weight formula, and performs differential compensation on each wheel to obtain the vehicle's final weight data. When the final weight data exceeds a preset load standard data, the vehicle is determined to be overloaded, and overload information is obtained. An overload alarm signal is generated based on the overload information, and the final weight data, overload information, and overload alarm signal are sent to the vehicle-mounted display unit for display to remind the user of overload. This solves the problem in related technologies where the lack of an effective load detection alarm method makes it impossible to accurately determine the vehicle's load status. Through the overload warning function, users can understand the overall status of the vehicle at any time, thereby accurately judging the vehicle's load status and avoiding unnecessary violations.
