[0048] 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 throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0049] The following describes the vehicle overload reminder method, device, vehicle and storage medium of the embodiment of the present application with reference to the accompanying drawings. In view of the problem that the related art mentioned in the above background technology cannot accurately judge the load condition of the vehicle due to the lack of an effective load detection alarm method, the present application provides a vehicle overload reminder method, in which, based on the height change data of the vehicle, the weight change data of each wheel of the vehicle is calculated using a preset weight formula, and each wheel is differentially compensated to obtain the final weight data of the vehicle. When the final weight data is greater than the preset load standard data, the vehicle is judged to be overloaded, the overload information of the vehicle is obtained, an overload alarm signal is generated according to 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. Thus, the problem that the related art cannot accurately judge the load condition of the vehicle due to the lack of an effective load detection alarm method is solved. Through the overload reminder function, the user is helped to understand the overall status of the vehicle at any time, thereby accurately judging the load condition of the vehicle to avoid unnecessary violations.

[0050] Specifically, Figure 1 A flowchart of a vehicle overload reminder method provided in an embodiment of the present application.

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

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

[0053] According to one embodiment of the present application, receiving height change data of a vehicle includes: identifying the movement state of the vehicle; when the vehicle is in a stationary state, receiving first height change data from the vehicle chassis to the ground in the stationary state; when the vehicle is in a moving state, receiving second height change data from the vehicle chassis to the ground in the moving state.

[0054] Specifically, Figure 2 As shown, in an embodiment of the present application, first, the height change data of the vehicle is obtained through a height sensor, mainly including that when the vehicle is in a stationary state, for example, a user gets on or off the vehicle, or cargo is added or removed from the cargo box, the height of the vehicle will change. At this time, the first height change data of the vehicle chassis relative to the ground can be obtained through the height sensor. When the vehicle is in motion, for example, the vehicle encounters different road conditions (such as bumps, ramps, etc.) during driving, which will also cause the height of the vehicle to change. At this time, the second height change data of the vehicle chassis relative to the ground can be obtained through the height sensor, and then the first height change data and the second height change data are converted into electrical signals and sent to PCDM (Partial chassis domain mode, chassis local domain control), hereinafter referred to as PCDM; secondly, after receiving the first height change data and the second height change data of the vehicle, PCDM realizes the signal output of the height change of the whole vehicle.

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

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

[0057] Specifically, in an embodiment of the present application, after receiving the height change data of the vehicle, the PCDM also needs to identify the height change data of the vehicle and verify the height change data of the vehicle. If there is abnormal data, it will be filtered out and the height change data of the vehicle will continue to be received until the height change data of the vehicle 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 the present application, each wheel is differentially compensated according to 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 differentially compensating the weight change data of each wheel based on the deviation to obtain the final weight data of the vehicle.

[0060] Among them, the preset weight formula can be set by those skilled in the art according to the actual control logic, and is not specifically limited here.

[0061] Specifically, in the embodiment of the present application, based on the above-obtained height change data of the vehicle chassis relative to the ground, first, the weight change data of each wheel of the vehicle is calculated according to the spring elastic coefficient and the height change data of the vehicle chassis relative to the ground using a preset weight formula, wherein the preset weight formula can be expressed as:

[0062] W = K × δH;

[0063] Wherein, W is the weight change data of each wheel, δH is the height change data of each wheel, and K is the spring elastic coefficient.

[0064] Secondly, in order to eliminate errors caused by uneven road surface or other factors and ensure the accuracy of the weight change data of each wheel, PCDM needs to perform differential compensation on 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 four wheels of the vehicle can be expressed as δH1, δH2, δH3 and δH4, respectively. The weight change data corresponding to each wheel is calculated by using the preset weight formula using the elastic coefficient of each wheel and the height change data of each wheel, which are expressed as W1, W2, W3 and W4, respectively. 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, and the weight change data of each wheel is differentially compensated based on the deviation. Then, the compensated weight change data corresponding to each wheel are added to obtain the final weight data of the vehicle, which is recorded and transmitted to the IHU (In-Vehicle Human Unit) via a CAN (Controller Area Network) signal. The IHU displays the received final weight data of the vehicle in real time on the on-board display screen.

[0066] For example, when the vehicle is stationary, such as when the user loads 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, and after calculating the deviation between the weight change data of each wheel and the average weight change data of all wheels, differential compensation is performed on the weight change data of each wheel based on the deviation, and the compensated weight change data corresponding to each wheel are added up to obtain the final weight data of the vehicle.

[0067] When the vehicle is in motion, for example, when the vehicle encounters bumps or slopes during driving, the height sensor will continue to monitor the second height change data of the vehicle chassis relative to the ground, and transmit the second height change data to PCDM in real time. PCDM will calculate the weight change data of each wheel of the vehicle based on the latest second height change data using a preset weight formula, and after calculating the deviation between the weight change data of each wheel and the average weight change data of all wheels, perform differential compensation on the weight change data of each wheel based on the deviation, and add up the weight change data corresponding to each wheel after compensation, so as to obtain the final weight data of the vehicle, so as to ensure the accuracy of 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 vehicle's 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.

[0069] According to one embodiment of the present application, after determining whether the final weight data is greater than the preset load-bearing standard data, it also includes: if the final weight data is less than or equal to the preset load-bearing standard data, it is determined that the vehicle is not overloaded, the vehicle's load-bearing information is obtained, and the final weight data and load-bearing information are sent to the vehicle-mounted display unit for display.

[0070] Among them, the preset load standard data can be set by technical personnel in this field according to the actual control logic, or can be obtained through a limited number of computer simulations. The overload information and load information may include the number of passengers in the vehicle or the amount of cargo loaded in the vehicle, etc., which are not specifically limited here.

[0071] Specifically, Figure 2 As shown, in an embodiment of the present application, based on the final weight data of the vehicle obtained as described 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 vehicle's overload information is obtained and an overload alarm signal is generated, and then the final weight data, overload information and overload alarm signal are sent to a vehicle-mounted display unit, such as an IHU. After receiving the final weight data, overload information and overload alarm signal of the vehicle, the IHU can display a "vehicle overload" warning message on the screen, or remind the user of the overload through a sound alarm; if the final weight data is less than or equal to the preset load standard data, the vehicle is determined to be not overloaded. At this time, the vehicle's load information is obtained, and the final weight data and load information are sent to the IHU for display.

[0072] In summary, based on the above-mentioned vehicle overload reminder method, the embodiment of the present application can achieve the following beneficial effects:

[0073] (1) Improved safety: The height sensor monitors the height change of the vehicle in real time, and can promptly detect the weight change of the vehicle and accurately determine whether the vehicle is overloaded. If the vehicle is overloaded, the on-board display unit can issue visual and auditory alarms to remind the driver to take timely measures to avoid safety accidents caused by overloading.

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

[0075] (3) Improve user experience. The vehicle's current weight and cargo volume can be displayed in real time through the on-board display unit, helping users better manage the vehicle's load. At the same time, visual and auditory reminders are provided to ensure that users can quickly notice overloading and take appropriate measures in a timely manner.

[0076] According to the vehicle overload reminder method of the embodiment of the present application, based on the height change data of the vehicle, the weight change data of each wheel of the vehicle is calculated using a preset weight formula, and each wheel is differentially compensated to obtain the final weight data of the vehicle. When the final weight data is greater than the preset load standard data, the vehicle is determined to be overloaded, and the vehicle 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 the overload. Thus, the problem that the load condition of the vehicle cannot be accurately judged due to the lack of an effective load detection alarm method in the related art is solved. Through the overload reminder function, the user is helped to understand the overall status of the vehicle at any time, thereby accurately judging the load condition of the vehicle to avoid unnecessary violations.

[0077] Next, the vehicle overload reminder device proposed in accordance with the embodiment of the present application will be described with reference to the accompanying drawings.

[0078] Figure 3 It is a block diagram of a vehicle overload reminder device according to an embodiment of the present application.

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

[0080] Wherein, the receiving module 100 is used to receive the height change 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 vehicle's overload information is obtained, an overload alarm signal is generated according to 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 an embodiment of the present application, the receiving module 100 is specifically configured to:

[0084] Identify the motion state of the vehicle;

[0085] When the vehicle is in a stationary state, receiving first height change data from the vehicle chassis to the ground in the stationary state;

[0086] When the vehicle is in motion, second height change data from the vehicle chassis to the ground of the vehicle in the motion state is received.

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

[0088] Identify whether there is abnormal data in the vehicle's height change data;

[0089] If there is abnormal data in the height change data of the vehicle, the abnormal data is filtered, and the height change data of the vehicle continues to be received until the height change data of the vehicle are all in a normal state.

[0090] According to one embodiment of the present application, the computing module 200 is specifically configured to:

[0091] Calculating average weight change data of all wheels based on the weight change data of each wheel;

[0092] The elastic coefficient of each wheel is used to calculate 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 the weight change data of each wheel is differentially compensated based on the deviation to obtain the final weight data of the vehicle.

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

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

[0095] According to the vehicle overload reminder device of the embodiment of the present application, based on the height change data of the vehicle, the weight change data of each wheel of the vehicle is calculated using a preset weight formula, and each wheel is differentially compensated to obtain the final weight data of the vehicle. When the final weight data is greater than the preset load standard data, the vehicle is determined to be overloaded, and the vehicle overload information is obtained. An overload alarm signal is generated according to 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 the overload. Thus, the problem that the load condition of the vehicle cannot be accurately judged due to the lack of an effective load detection alarm method in the related art is solved. Through the overload reminder function, the user is helped to understand the overall status of the vehicle at any time, thereby accurately judging the load condition of the vehicle to avoid unnecessary violations.
