[0055] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0056] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0057] During vehicle operation, the vehicle's weight is a key factor affecting its handling performance, driving stability, and driving safety. Whether it's the passenger situation during daily commutes, the total amount of luggage carried on long-distance trips, or the stacking of temporary items, changes in the vehicle's overall weight directly affect the vehicle's posture and wheel load distribution.
[0058] For example, exceeding safe weight limits can lead to sluggish steering response, increased vehicle pitching during braking, and reduced crosswind resistance at high speeds. Furthermore, for electric vehicles, unreasonable weight loading can cause uneven battery pack load, indirectly reducing energy conversion efficiency and increasing unnecessary energy consumption. Therefore, effective monitoring and management of vehicle weight is a crucial foundation for ensuring overall vehicle performance and driving safety.
[0059] Currently, some vehicles are equipped with basic weight monitoring systems. These systems typically use pressure sensors placed under the seats to detect occupant seating status and weight sensors in the chassis or trunk to detect the total load, ultimately achieving real-time monitoring of the vehicle's total weight. Their primary function focuses on overload warnings. Specifically, when the system detects that the vehicle's total weight exceeds the factory-set rated threshold (e.g., the rated load for passenger cars is typically 375kg-500kg), it reminds the user to reduce the load through dashboard warning lights, text prompts on the central control screen, or voice announcements. In addition, some systems further integrate seat pressure sensors to provide supplementary basic safety reminders such as not wearing seat belts.
[0060] However, in practical applications, even if the total vehicle weight meets safety standards, it may still lead to a decrease in vehicle handling performance. The aforementioned system cannot provide warnings for such situations, thus posing a deficiency that is detrimental to ensuring driving safety.
[0061] Therefore, this application provides an information prompting method, apparatus, device, medium, computer program product, and system to solve the above-mentioned problems. The method of this application proposes to combine the current center of gravity offset index to provide corresponding intelligent driving prompt information. Specifically, the method of this application calculates the dynamic center of gravity position of the vehicle based on the vehicle's current comprehensive load information, determines the vehicle's current center of gravity offset index based on the dynamic center of gravity position and the reference center of gravity position, and then generates and feeds back driving prompt information based on the center of gravity offset index.
[0062] It is understood that the information display method of this application can be applied to any vehicle. As an example, Figure 1 A schematic diagram illustrating the application scenario of the information prompting method provided in this application, such as... Figure 1 As shown, the information prompting method of this application can be executed by the vehicle controller.
[0063] Specifically, the vehicle controller calculates the vehicle's dynamic center of gravity position based on the vehicle's current comprehensive load information. Then, it determines the vehicle's current center of gravity offset index based on the dynamic center of gravity position and the reference center of gravity position. Finally, it generates and feeds driving prompt information to the vehicle's central control screen based on the center of gravity offset index.
[0064] With the above settings, users can intuitively obtain driving prompts related to center of gravity shift through the central control screen (such as prompts: the left side of the trunk is too heavy, it is recommended to adjust the luggage position), and adjust the vehicle load distribution in time to reduce the risk of center of gravity shift, effectively improve vehicle handling performance and driving stability, make up for the shortcomings of known technologies that the system only monitors the total weight and cannot prompt the problem of center of gravity shift, and further ensure vehicle driving safety from a technical point of view.
[0065] It should be understood that, for the above scenario example, the vehicle controller may also provide driving prompts to the user's terminal in the vehicle, or the vehicle controller may directly provide driving prompts to the corresponding actuators in the vehicle. This embodiment does not limit this.
[0066] Furthermore, it should be understood that, in addition to the vehicle scenario described above, the information prompting method of this application can also be used in any scenario such as ships or airplanes where driving / navigation / flight safety and handling stability can be ensured through load distribution optimization. This embodiment does not limit this to such scenarios.
[0067] The technical solution of this application and how it solves the above-mentioned technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings, using an electronic device as the execution subject and taking an application in any vehicle as an example.
[0068] This embodiment provides an information prompting method. Figure 2 Flowchart of the information prompting method provided in this application Figure 1 ,like Figure 2 As shown, the method in this embodiment includes:
[0069] S201, based on the vehicle's current comprehensive load information, calculates the vehicle's dynamic center of gravity position.
[0070] Among them, the comprehensive load information is determined based on the load information of each preset detection location inside the vehicle.
[0071] In this embodiment, the electronic device first determines the total vehicle load information based on the comprehensive load information and the vehicle's unloaded information. Subsequently, the electronic device determines the target detection position from each preset detection position, and calculates the dynamic center of gravity position based on the coordinate information, load information, and comprehensive load information corresponding to each target detection position.
[0072] Specifically, in this embodiment, the electronic device determines the preset detection position where the pressure value indicated by the load information is not zero as the target detection position, and the coordinate information corresponding to the target detection position is obtained based on the preset vehicle coordinate system.
[0073] More specifically, Figure 3 A schematic diagram illustrating the principle of the vehicle coordinate system and center of gravity definition provided in this application. Figure 3 As shown in (1) and (2) in this embodiment, the reference center of gravity of the vehicle is taken as the origin of the coordinate system, the length direction of the vehicle is taken as the x-axis, the width direction of the vehicle is taken as the y-axis, the direction perpendicular to the ground is taken as the z-axis, the forward direction of the vehicle is taken as the positive direction of the x-axis, the passenger side of the vehicle is taken as the positive direction of the y-axis, and the direction away from the ground is taken as the positive direction of the z-axis, thus establishing the preset vehicle coordinate system.
[0074] Based on this, in this embodiment, the center position of each seat is configured as a preset detection position. Based on the vehicle coordinate system described above, the coordinate information of each preset detection position can be obtained: (x1, y1, z1), (x2, y2, z2), (x3, y3, z3), (x4, y4, z4). In this embodiment, the coordinate information of each position is stored as vehicle configuration information. Based on this setting, the electronic device can obtain the coordinate information of the corresponding position through the vehicle configuration information.
[0075] It should be understood that in practical applications, the vehicle width direction can also be used as the x-axis and the vehicle length direction as the y-axis. Similarly, the positive and negative directions of each coordinate axis can be defined in other ways, and a two-dimensional vehicle coordinate system can also be established. This embodiment does not limit this, as long as the coordinate information of each preset detection position and the reference center of gravity position is obtained based on the same vehicle coordinate system. In addition, in practical applications, the trunk or the middle position of adjacent seats can also be configured as the preset detection position, and this embodiment does not limit this either.
[0076] In this embodiment, the vehicle is equipped with an on-board weight sensing system, which includes multiple pressure sensors. Specifically, at least one pressure sensor is installed at each preset detection location, and the pressure sensors corresponding to each preset detection location constitute the on-board weight sensing system. Electronic devices obtain load information at each preset detection location by interacting with this on-board weight sensing system.
[0077] More specifically, in this embodiment, at least two pressure sensors are provided at each preset detection position. The load information for the corresponding preset detection position is obtained by averaging the pressure values output by the at least two pressure sensors. In practical applications, only one pressure sensor may be provided at each preset detection position, in which case the pressure value output by that pressure sensor is used as the load information for the corresponding preset detection position. This embodiment does not limit this.
[0078] Based on the above settings, in this embodiment, when determining the current dynamic center of gravity position, the electronic device first obtains the load information corresponding to each preset detection position through the vehicle-mounted weight sensing system, and sums the pressure values indicated by each load information to obtain comprehensive load information. Then, based on the load information of each preset detection position, it determines the target detection position with a non-zero pressure value, and obtains the coordinate information of the target detection position from the vehicle configuration information. In addition, it also obtains the vehicle's unloaded information from the vehicle configuration information, and determines the vehicle's total load information based on the vehicle's unloaded information and the comprehensive load information. Finally, substituting the vehicle's total load information, the coordinate information of the target detection position, and the load information into the following formula, the current dynamic center of gravity position is obtained: CG=(x_CG, y_CG, z_CG)=(1 / M) Σ(mi xi,mi yi, mi zi).
[0079] In the above calculation formula, CG is used to represent the dynamic center of gravity position, x_CG, y_CG, z_CG are used to represent its coordinate information, M is used to represent the total vehicle load information, mi is used to represent the load information corresponding to the i-th target detection position, and xi, yi, zi are used to represent the coordinate information of the i-th target detection position.
[0080] It should be understood that in practical applications, electronic devices may also use a preset detection position where the pressure value indicated by the load information is greater than a preset threshold as the target detection position. The preset threshold is a small value, and this embodiment does not limit this.
[0081] In this embodiment, by accurately selecting target detection locations with loads from various preset detection locations and combining their coordinate information with load information to calculate the dynamic center of gravity position, the distribution characteristics of the vehicle's preset detection locations can be fully utilized. This ensures that all load data involved in the calculation are effective loads, avoids interference from unloaded locations on the calculation results, and improves the calculation accuracy of the dynamic center of gravity position. Simultaneously, quantitative calculation based on coordinate information under a unified vehicle coordinate system makes the numerical representation of the dynamic center of gravity position more objective and consistent, laying a reliable foundation for the accurate determination of the subsequent center of gravity offset index. This, in turn, ensures the accuracy and effectiveness of driving prompts, ultimately achieving refined monitoring and management of the vehicle's load distribution status.
[0082] S202 determines the vehicle's center of gravity offset index based on the dynamic center of gravity position and the vehicle's reference center of gravity position.
[0083] The center of gravity offset index is determined based on the offset of the dynamic center of gravity position from the reference center of gravity position in different directions.
[0084] In this embodiment, the electronic device determines the center of gravity offset index based on the coordinate information of the dynamic center of gravity position and the coordinate information of the vehicle's reference center of gravity position. The coordinate information of the dynamic center of gravity position is obtained based on the aforementioned calculation process, while the coordinate information of the reference center of gravity position is the coordinate of the vehicle's center of mass when unloaded, which is obtained through vehicle configuration information.
[0085] Specifically, in this embodiment, the electronic device first determines the offset in each direction based on the dynamic center of gravity position and the vehicle's reference center of gravity position; then, based on the offset in each direction and the vehicle's geometric parameters, it obtains the center of gravity offset index.
[0086] In this embodiment, each direction includes three directions: the x-axis, the y-axis, and the z-axis. The electronic device calculates the coordinate difference between the dynamic center of gravity position and the reference center of gravity position on the corresponding coordinate axes to obtain the center of gravity offset in each direction. Specifically, the offset in the x-axis direction is δx = x_CG - x0, the offset in the y-axis direction is δy = y_CG - y0, and the offset in the z-axis direction is δz = z_CG - z0, where (x0, y0, z0) are the coordinate information of the reference center of gravity position, and (x_CG, y_CG, z_CG) are the coordinate information of the dynamic center of gravity position.
[0087] In this embodiment, the vehicle's geometric parameters include vehicle length, wheelbase, and the allowable vertical displacement range of the suspension's center of gravity. It should be understood that the vehicle's geometric parameters are also obtained through vehicle configuration information.
[0088] Furthermore, as a possible approach, the dimensionless centroid offset index can be obtained by summing the squares of the ratios of the offsets in each direction to the corresponding geometric parameters. The formula is: Centroid offset index = (δx / Lx) 2 +(δy / Ly) 2 +(δz / Lz) 2 Where Lx is the reference length parameter in the x-axis direction (based on vehicle length), Ly is the reference width parameter in the y-axis direction (based on vehicle track width), and Lz is the reference vertical parameter in the z-axis direction (i.e., the allowable vertical displacement range of the suspension center of gravity).
[0089] As an example, assume the vehicle length L_car = 4.5m, track width W = 1.6m, and the allowable vertical displacement range of the center of gravity Lz = 0.08m. Let Lx = 0.45L_car = 2.025m, Ly = 0.45W = 0.72m. If we calculate δx = 0.3m, δy = 0.15m, and δz = 0.02m, then the center of gravity offset index = (0.3 / 2.025). 2 +(0.15 / 0.72) 2 +(0.02 / 0.08) 2 ≈0.022+0.043+0.062=0.127, this value can be used to quantitatively assess the overall degree of center of gravity shift.
[0090] In practical applications, this can also be achieved by assigning different weights to the offset ratios in each direction and then summing them, such as the centroid offset index = a. (δx / Lx)²+b (δy / Ly)²+c (δz / Lz)², where a, b, and c are weighting coefficients set based on vehicle characteristics, and a+b+c=1. This embodiment does not impose any restrictions on this.
[0091] In this embodiment, by first calculating the center of gravity offset in each direction and then combining it with vehicle geometric parameters to convert the offset into a dimensionless center of gravity offset index, a quantitative assessment of the vehicle's center of gravity offset state can be achieved. Compared to judging the degree of offset solely through qualitative description, this method can accurately reflect the comprehensive impact of the offset through specific numerical values, avoiding subjective judgment errors. Simultaneously, it supports multiple calculation methods such as sum of squares and weighted summation, adapting to the geometrical differences of different vehicle models (e.g., sedans, SUVs) and meeting the assessment focus requirements of offset risk in different scenarios (e.g., long-haul freight focuses more on lateral offset along the y-axis, increasing the weight of Ly-related factors). Ultimately, this provides a reliable basis for generating accurate driving prompts, effectively improving the flexibility and practicality of vehicle load management.
[0092] S203 generates and provides driving prompts based on the center of gravity offset index.
[0093] Among them, the driving prompt information is used to prompt the user to adjust the vehicle's load distribution mode, so that the center of gravity offset index is minimized.
[0094] Specifically, in this embodiment, the electronic device first acquires at least one load allocation method to be confirmed; then, based on the center of gravity offset index corresponding to the load allocation method to be confirmed, it determines a target load allocation method from the at least one load allocation method to be confirmed; finally, it generates and feeds back driving prompt information based on the target load allocation method. Among them, the target load allocation method has the smallest center of gravity offset index.
[0095] More specifically, as one possible approach, this embodiment determines the target load allocation method by combining exhaustive search with heuristic algorithms. The electronic device first exhaustively searches for load adjustment schemes within a preset range based on the current load distribution state (such as passenger swapping between different seats, moving luggage within the trunk, etc.). Then, it uses heuristic algorithms (such as simulated annealing) to quickly calculate and filter the center of gravity offset index corresponding to each scheme, prioritizing the scheme with the smaller index and iteratively optimizing it to finally determine the target load allocation method with the smallest center of gravity offset index.
[0096] In practical applications, electronic devices can also use model prediction to determine the target load distribution method. By using a trained load distribution model, the center of gravity offset index under different adjustment methods can be directly predicted, and then the optimal solution can be selected. This embodiment does not limit this.
[0097] Furthermore, in practical applications, electronic devices can also use rule-based matching to match the current center of gravity offset characteristics with typical offset scenarios and corresponding optimal adjustment strategies stored in a preset rule base to quickly obtain the target load allocation method. Alternatively, the allocation method can be generated in conjunction with the vehicle's driving status; this embodiment does not limit this approach.
[0098] In this embodiment, by selecting the target load distribution method that minimizes the center of gravity offset index based on the center of gravity offset index and generating driving prompt information, the system can provide users with accurate and operable load adjustment guidance. This avoids users being unable to effectively improve the center of gravity offset problem due to a lack of professional knowledge, reduces driving risks caused by unreasonable load distribution from the perspective of proactive intervention, and improves the convenience and effectiveness of users' vehicle load management through clear prompt information, further optimizing the vehicle's handling performance and driving stability.
[0099] In addition, in this embodiment, the driving prompt information includes at least one of visual prompts, auditory prompts, or tactile prompts; and / or, the driving prompt information includes prompts suggesting adjustments to seat position, luggage placement, or passenger seating position.
[0100] As an example, when the system detects excessive offset in the y-axis direction, it provides a visual prompt via the central control screen. Specifically, it displays a driving prompt message on the central control screen stating, "The luggage on the left is too heavy; it is recommended to move the luggage on the right to the left to balance the weight." Simultaneously, it provides an auditory prompt via the car's audio system, specifically a "ding-dong" sound. If the system detects excessive offset in the x-axis direction, it provides a tactile prompt through slight vibration of the steering wheel, combined with a voice announcement stating, "The rear seats are overloaded; it is recommended that one passenger move to the front."
[0101] In the method provided in this application embodiment, firstly, comprehensive load information is determined based on the load information of each preset detection position inside the vehicle. Then, the dynamic center of gravity position of the vehicle is calculated based on the comprehensive load information. Subsequently, the center of gravity offset index is determined by combining the dynamic center of gravity position with the vehicle's reference center of gravity position. Finally, driving prompt information is generated and fed back based on the center of gravity offset index to prompt the user to adjust the load distribution method.
[0102] The method described in this embodiment achieves accurate perception and quantitative assessment of the vehicle's dynamic center of gravity position, enabling the identification of potential risks arising from a compliant gross weight but center of gravity shift. Furthermore, by generating targeted driving prompts, it provides users with actionable load distribution methods, preventing users from being unable to optimize load distribution due to a lack of professional knowledge and proactively reducing handling risks caused by center of gravity shift. Moreover, the method in this embodiment relies on existing vehicle configurations, balancing technical feasibility and cost-effectiveness, and can be widely adapted to different types of vehicles, simultaneously improving vehicle driving safety, handling stability, and user convenience.
[0103] In addition, in this embodiment, the electronic device is equipped with a preset load threshold. After calculating the total vehicle load information based on the comprehensive load information and the vehicle empty load information, the electronic device compares the total vehicle load information with the preset load threshold and issues an overload warning when the pressure value indicated by the total vehicle load information exceeds the pressure value indicated by the preset load threshold.
[0104] This application also provides an embodiment of an information prompting method, which provides a detailed description of the specific method for generating driving prompt information. Figure 4 Flowchart of the information prompting method provided in this application Figure 2 ,like Figure 4 As shown, the method in this embodiment includes:
[0105] S401, determine the preset index range to which the center of gravity offset index belongs.
[0106] S402, based on the warning level corresponding to the preset index range, generates driving warning information for providing warnings at the corresponding warning level.
[0107] The larger the endpoint value of the preset index range, the higher the warning level, and the clearer the warning intensity or adjustment suggestion of the corresponding driving prompt information.
[0108] In this embodiment, the electronic device is configured with multiple preset index intervals, and each preset index interval is configured with a different prompt level, so that the preset index interval with a larger endpoint value corresponds to a higher prompt level. Subsequently, a mapping relationship between each preset index interval and the prompt level is established. It should be understood that the endpoint values of the preset index intervals should be endpoint values on the same side, that is, uniformly comparing the upper limit value or the lower limit value of the interval.
[0109] For example, the preset index range can be divided into: [0, 0.3), [0.3, 0.45), [0.45, 0, 65), [0.65, +∞), with corresponding prompt levels of Level 1 (minimal offset), Level 2 (slight offset), Level 3 (moderate offset), and Level 4 (severe offset). The endpoint values of each range increase with the prompt level, and the endpoint values of adjacent ranges are continuously connected to ensure that any center of gravity offset index can match a unique range.
[0110] Based on this, after calculating the center of gravity offset index, the electronic device matches the corresponding preset index range according to the center of gravity offset index, obtains the corresponding prompt level according to the mapping relationship, and generates driving prompt information according to the prompt level.
[0111] For example, if the calculated center of gravity offset index is 0.25, which falls within the preset index range [0, 0.3), it is determined to be a very small offset, and no prompt information is generated. If the center of gravity offset index is 0.38, which falls within the preset index range [0.3, 0.45), it corresponds to a low-level prompt for a slight offset. The central control screen displays the text prompt "The seating position can be optimized" and simultaneously displays a graphical seat distribution interface. The interface uses different colors to indicate the current load of each seat (e.g., red indicates a heavy load, blue indicates a light load), and arrows indicate suggested adjustment scheme P (e.g., "Please move the rear left passenger to the front passenger seat").
[0112] If the center of gravity offset index is 0.55, which falls within the preset index range [0.45, 0.65), it corresponds to a moderate offset warning, displaying the text "It is recommended to adjust the seating distribution," and enhancing the color contrast in the graphical seating interface. The description of Option P is also clearer (e.g., "Move one of the two rear right-side passengers to the left row and the middle front row"). If the center of gravity offset index is 0.7, which falls within the preset index range [0.65, +∞), it corresponds to a significant offset warning. The central control screen displays "Current unbalanced load distribution, affecting energy consumption and safety" with a red warning box, accompanied by an urgent warning sound and seat vibration. The risk area is highlighted in the graphical interface, and the adjustment priority is added in Option P (e.g., "1. Prioritize moving one rear right-side passenger to the front row; 2. Next, move the luggage from the left rear to the right side for balance").
[0113] Optionally, the driving prompt information is also used to prompt the user to adjust the vehicle's driving mode. In addition, when generating driving prompt information, the electronic device will specifically generate driving prompt information containing corresponding driving mode suggestions based on the preset index range to which the center of gravity offset index belongs; wherein, the driving mode suggestions include prompts that do not recommend using a specific driving mode or prompts that recommend using a specific driving mode.
[0114] Specifically, the driving modes include Sport and Comfort modes. It should be understood that in Sport mode, the vehicle's power response is more sensitive and the handling is more aggressive, which can exacerbate the risk of vehicle instability when the center of gravity shifts. In Comfort mode, the vehicle's suspension is tuned more softly and the power output is smoother, which can offset the impact of center of gravity shift on the driving experience to some extent.
[0115] Based on this, in this embodiment, the electronic device is configured with a correspondence rule between a preset offset index range and driving mode recommendations. Specifically, this correspondence rule is established by analyzing the actual performance of different driving modes under center of gravity offset conditions. More specifically, when the center of gravity offset index is in the range of [0.3, 0.45), considering the sensitivity of the sport mode to changes in the center of gravity, activating the sport mode at this time would amplify the offset and bring instability risks. Therefore, a driving mode recommendation rule of "uneven load distribution, it is not recommended to activate sport mode" is configured. When the center of gravity offset index is in the range of [0.45, 0.65), the stability characteristics of the comfort mode can better adapt to the current center of gravity state. Therefore, a driving mode recommendation rule of "uneven load distribution, it is recommended to activate comfort mode" is configured.
[0116] As an example, in this embodiment, if the center of gravity offset index = 0.32, which falls within the preset index range [0.3, 0.45], corresponding to a moderate level of slight offset, the central control screen displays the text message "Current load distribution is uneven, it is not recommended to turn on Sport mode," and at the same time, Sport mode is highlighted and marked with a prohibition symbol on the driving mode selection interface; if the center of gravity offset index = 0.5, which falls within the preset index range (0.45, 0.65), corresponding to a moderate level of slight to moderate offset, the text message "Current load distribution is uneven, it is recommended to turn on Comfort mode" is displayed, and Comfort mode is automatically recommended and a one-click switching option is provided on the driving mode selection interface.
[0117] The method provided in this embodiment divides the center of gravity shift index into different preset index ranges and configures a grading rule where the larger the endpoint value, the higher the prompt level. This enables precise matching and differentiated prompts for center of gravity shift risks. Based on this, low-intensity prompts are used when the shift is small to avoid disturbing the user, while high-intensity prompts are used when the shift is severe to strengthen the warning and provide clear adjustment suggestions. This allows users to intuitively perceive the risk level and determine the priority of actions without relying on professional knowledge. Furthermore, the precise correspondence between risk and prompts ensures that high-risk scenarios such as severe shifts are addressed promptly, effectively reducing safety hazards caused by ambiguous prompts, while also optimizing the user experience of receiving prompts.
[0118] Furthermore, the method in this embodiment expands the dimensions of information prompts by adding driving mode suggestions on top of tiered prompts, forming a dual intervention system of load adjustment and mode adaptation. Combining the characteristics of different driving modes (e.g., aggressive Sport mode and gentle Comfort mode), it provides guidance on whether to recommend or discourage activation based on the degree of center of gravity shift. This not only allows for temporary adaptation to the center of gravity state and reduces handling risks when load cannot be immediately adjusted (e.g., while driving), but also ensures that driving behavior is more closely matched to the vehicle's current center of gravity characteristics, further guaranteeing driving safety while reducing the impact of center of gravity shift on ride comfort, and adapting to more complex usage scenarios.
[0119] This application also provides an embodiment of an information prompting method, which provides a detailed description of the specific method for generating driving prompt information. Figure 5 Flowchart of the information prompting method provided in this application Figure 3 ,like Figure 5 As shown, the method in this embodiment includes:
[0120] S501, obtain vehicle driving status information.
[0121] S502 generates driving prompts containing safety warnings based on the center of gravity offset index and driving status information.
[0122] In this embodiment, the electronic device obtains the vehicle's driving status information by interacting with sensors inside the vehicle. For example, it obtains dynamic parameters such as lateral acceleration and speed of the vehicle through the onboard inertial measurement unit, and collects changes in pressure values of each seat in real time through seat pressure sensors to determine the occupant's positional status.
[0123] One possible approach is to include lateral acceleration in the driving status information. Based on this, when the absolute value of the lateral offset indicated by the center of gravity offset index is greater than a first threshold, and the absolute value of the lateral acceleration is greater than a second threshold, the electronic device generates a driving warning message containing safety information indicating a risk to roll comfort.
[0124] Specifically, in this embodiment, the first threshold is set to 0.2m (i.e., the lateral center of gravity offset ΔCGy > 0.2m), and the second threshold is set to 1.0m / s. 2 (That is, the absolute value of the lateral acceleration |ay|>1.0m / s²) 2 When both conditions are met, the system determines that there is a comfort risk in the current load configuration and triggers a medium-level warning. The central control screen displays "The current lateral acceleration is too fast, which may cause discomfort to the right (left) passenger. It is recommended to reduce speed appropriately," accompanied by a gentle warning sound to avoid interfering with driving.
[0125] It should be understood that in practical applications, the first and second thresholds can be adjusted to other values based on vehicle characteristics (such as the difference in wheelbase between sedans and SUVs) and vehicle design safety standards. For example, when an SUV has a wider wheelbase, the first threshold can be set to 0.25m, and the second threshold can be dynamically adjusted based on the safe acceleration range under different road conditions (such as urban roads and highways). Furthermore, the warning level is set to medium, which is consistent with the grading logic of "slight deviation corresponds to low level, moderate deviation corresponds to medium level" in the aforementioned embodiment (lateral comfort risk belongs to moderate safety hazard, not reaching the severe danger level). It can also be flexibly adapted according to actual scenario needs. For example, for scenarios with higher safety requirements, such as commercial vehicles, the warning level can be upgraded to high level. This embodiment does not limit this.
[0126] In this embodiment, combining lateral acceleration to generate driving warning information combines the static center of gravity shift state with the dynamic vehicle driving conditions, avoiding the limitations of judging risk solely based on the amount of center of gravity shift. For example, a lateral shift of 0.2m when the vehicle is stationary may have no impact, but during high-speed lane changes (with large lateral acceleration), it will exacerbate the centrifugal force superposition effect. Timely warnings to slow down can effectively alleviate passenger discomfort, reduce the risk of vehicle roll, and make safety warnings more relevant to actual driving scenarios, improving the timeliness and accuracy of the warnings.
[0127] As another possible approach, driving status information includes changes in the occupants' positions within the vehicle. Based on this, when electronic devices detect a change in occupant position during vehicle movement, and the change in the center of gravity offset index exceeds a preset amount, they generate driving alert information containing safety warnings indicating the risk of occupant movement.
[0128] Specifically, the electronic device detects a sudden decrease in the pressure value of one side of the middle or rear seat and a rapid increase in the pressure value of the other seat through the seat pressure sensor. At the same time, the center of gravity calculation module detects a sudden shift in the lateral center of gravity (CGy). When the on-board inertial measurement unit determines that the vehicle is in motion and the preset change amount is set to 0.15m (i.e., the change in CGy exceeds 0.15m), it determines that the occupant has changed seats while the vehicle is in motion, triggering an advanced prompt that displays "Occupant has changed seats while the vehicle is in motion. There is a risk. Please take your seat immediately," accompanied by an urgent prompt sound to reinforce the warning.
[0129] It should be understood that sudden decreases, rapid increases, and sudden shifts can be determined using preset time and magnitude thresholds. For example, a decrease of more than 50% in seat pressure within one second is considered a sudden decrease; an increase of more than 30% in the pressure of another seat within the same time period is considered a rapid increase; and a shift of more than 0.1m in the lateral center of gravity within two seconds is considered a sudden shift. In practical applications, the preset change amount can be adjusted based on parameters such as seat spacing and vehicle width. For example, when the seat spacing in a microcar is relatively close, the preset change amount can be set to 0.1m to ensure accurate detection of risky positional changes. This embodiment does not impose such limitations.
[0130] In this embodiment, driving prompts are generated by combining changes in occupant position, enabling proactive identification of dynamic risks during driving (such as temporary occupant seat changes), rather than simply monitoring static load distribution. Seat changes during driving can not only cause a sudden shift in the center of gravity affecting handling, but may also pose safety hazards to occupants due to not wearing seatbelts or loss of balance. In such cases, timely warnings via advanced prompts can alert the driver to intervene and prevent the risk from escalating, filling the gap in traditional static load monitoring that cannot cover dynamic scenarios.
[0131] As a preferred example, the driving status information includes both the aforementioned lateral acceleration and the occupant's positional changes within the vehicle. Based on this, the electronic equipment will comprehensively assess the risk level by considering both dimensions: if the lateral shift in the center of gravity due to occupant changing seats exceeds 0.2m, and the vehicle's lateral acceleration is greater than 1.0m / s², then a combination of comfort risk and occupant movement risk will be triggered, leading to a higher-level warning. For example, a red warning box on the central control screen will display "Occupant changing seats while driving and excessive lateral acceleration pose a dual risk to safety and comfort. Please immediately slow down and remind the occupant to sit properly," while the seat vibrates to enhance the driver's perception.
[0132] In practical applications, other driving status information can also be referenced to generate driving prompts, such as the vehicle's longitudinal acceleration (rapid acceleration, sudden braking). When the absolute value of the longitudinal acceleration is greater than 1.5 m / s², the driving prompts can be generated accordingly. 2 Furthermore, if the longitudinal offset of the center of gravity exceeds 0.3m, it indicates that rapid acceleration / sudden braking may cause imbalance of the front and rear loads, and it is recommended to operate smoothly. This embodiment does not impose this limitation.
[0133] As a further preferred design, when the electronic device changes the status indication of the occupant position and the change in the center of gravity offset index during the change process is greater than the preset change amount, the occupant type is further identified based on the load data collected by the seat pressure sensor: if the load mass of the changed seat is less than 40kg and the pressure distribution is concentrated and the coverage area is consistent with the characteristics of a child riding (such as avoiding the edge area of the seat), it is determined that the child occupant is moving.
[0134] In this embodiment, in addition to triggering the advanced prompt "A child has been detected changing seats while the vehicle is in motion. This poses a high risk. Please immediately confirm the child's safety and remind them to sit down," the electronic device will also simultaneously activate the child safety lock function (if the vehicle is equipped with one). This will temporarily lock the corresponding side door to prevent the child from accidentally opening it. Furthermore, it will push a warning message containing "time of occurrence and vehicle location" to the parent's mobile app, forming a closed loop of "risk identification - warning reminder - safety protection - remote notification" to more accurately ensure the safety of children while traveling.
[0135] The method provided in this embodiment generates safety warning information by combining static center of gravity offset index with dynamic vehicle driving status information. This breaks the limitation of relying solely on single static data to judge risks, making safety prompts more relevant to actual driving scenarios. For example, when a vehicle changes lanes at high speed (with large lateral acceleration), combining the lateral center of gravity offset can accurately indicate risks to occupant comfort; when occupants change seats while the vehicle is in motion (position change state), combining the change in center of gravity offset can promptly indicate movement risks, effectively avoiding the problem of delayed or misjudged warnings due to deviating from dynamic operating conditions.
[0136] Furthermore, the method in this embodiment covers both static load distribution issues and potential hazards caused by sudden changes in the center of gravity and operating conditions during dynamic driving, forming a more comprehensive safety warning system. This helps drivers perceive hidden risks that cannot be directly observed (such as passengers quietly changing seats or acceleration superimposed on center of gravity shift), and guides them to take appropriate measures through targeted warnings (such as deceleration and reminding passengers to sit down), ultimately significantly improving the safety of vehicle driving and the comfort of passenger riding.
