[0045] The following will be described in detail a vehicle axle load calculation method provided by the embodiments of the present application.

[0046] Referring to Figure 1 Fig. 1 is a flowchart of a vehicle axle load calculation method provided by the embodiments of the present application. The specific execution process of the vehicle axle load calculation method is as follows:

[0047] S101, in response to a vehicle axle load evaluation request initiated by a target user in a vehicle axle load evaluation interface, acquiring the number of each row of seats, the curb weight, the wheelbase, the curb weight front axle load ratio and the position information of the target passenger car input by the target user in the vehicle axle load evaluation interface.

[0048] S102, calculate rear axle load data according to the target passenger car's kerb mass, wheelbase, front axle load ratio in kerb state and position information.

[0049] S103, determine all load conditions of the target passenger car according to the number of seats in each row of the target passenger car.

[0050] S104, calculate the vehicle load in each load condition according to the kerb mass, rear axle load data, the number of passengers in each row of seats in each load condition and the number of luggage.

[0051] The embodiment of the application provides a vehicle axle load calculation method, which comprises the following steps: in response to a vehicle axle load evaluation request initiated by a target user in a vehicle axle load evaluation interface, obtaining the number of seats in each row of a target passenger car, the kerb mass, the wheelbase, the front axle load ratio in the kerb state and the position information input by the target user in the vehicle axle load evaluation interface; calculating rear axle load data according to the kerb mass, the wheelbase, the front axle load ratio in the kerb state and the position information of the target passenger car. Determine all load conditions of the target passenger car according to the number of seats in each row of the target passenger car; calculate the vehicle load in each load condition according to the kerb mass, the rear axle load data, the number of passengers in each row of seats in each load condition and the number of luggage. Through the method of the application, the vehicle load in multiple load conditions can be calculated.

[0052] The exemplary steps of the embodiment of the application are described below:

[0053] S101, in response to a vehicle axle load evaluation request initiated by a target user in a vehicle axle load evaluation interface, obtaining the number of seats in each row of a target passenger car, the kerb mass, the wheelbase, the front axle load ratio in the kerb state and the position information input by the target user in the vehicle axle load evaluation interface.

[0054] In the embodiment of the application, Matlab2022b and above environment is obtained, and the vehicle axle load evaluation interface executed is built by using the appdesigner module. Through the text field component block, the parameter fields required for calculating the vehicle load are set in the vehicle axle load evaluation interface, including the number of seats in each row of the target passenger car field, the kerb mass field, the wheelbase field, the front axle load ratio in the kerb state field and the position information field.

[0055] The target user inputs the number of seats in each row, the kerb weight, the wheelbase, the kerb weight ratio of the front axle and the position information of the target passenger car in the vehicle axle load evaluation interface, and then responds after the target user clicks the calculation button, that is, in response to the vehicle axle load evaluation request initiated by the target user in the vehicle axle load evaluation interface, the number of seats in each row, the kerb weight, the wheelbase, the kerb weight ratio of the front axle and the position information of the target passenger car input by the target user in the vehicle axle load evaluation interface are obtained.

[0056] The target passenger car contains two axles. The kerb weight refers to the weight of the car before normal driving, that is, the empty car weight. The wheelbase refers to the distance from the center of the front axle to the center of the rear axle. The kerb weight ratio of the front axle refers to the ratio of the weight borne by the front axle to the total weight of the target passenger car in the kerb state (i.e. the state when no passengers or cargo are loaded). The position information includes the front wheel center coordinates, the seat reference point coordinates of each row of seats and the center of mass coordinates of the luggage; the midpoint of the line connecting the last point of the target passenger car and the rear wheel center is taken as the center of mass of the luggage in the embodiment of the application.

[0057] Here, the position information refers to the coordinate on the X-axis in the vehicle coordinate system of the target passenger car, that is, the front wheel center coordinates refer to the coordinate of the front wheel center on the X-axis in the vehicle coordinate system of the target passenger car, the seat reference point coordinates of each row of seats refer to the coordinate of the seat reference point of each row of seats on the X-axis in the vehicle coordinate system of the target passenger car, and the center of mass coordinates of the luggage refer to the coordinate of the center of mass of the luggage on the X-axis in the vehicle coordinate system of the target passenger car.

[0058] Wherein, in the vehicle coordinate system (also known as vehicle coordinate system), the determination of the direction is based on the driver's perspective, and this coordinate system follows the ISO8855 / DIN70000 standard, ensuring consistency in different vehicles and scenarios. Specifically, the X-axis represents the longitudinal direction of the vehicle, and when observing the front of the vehicle, the positive direction of the X-axis is along the center line of the vehicle pointing to the forward direction of the vehicle. The Y-axis is the lateral direction, which is in the same plane as the X-axis and is perpendicular to the X-axis pointing to the left. Finally, the Z-axis represents the vertical direction, which is perpendicular to the XY plane and the positive direction is upward.

[0059] In addition, the seating reference point is a design reference point at the design stage, also known as the R point, which represents a specific position in the vehicle design, namely the "seating reference point". This concept is particularly important in automobile design, which refers to the design H point specified by the manufacturer, that is, the reference position when the passenger is seated in the vehicle. The establishment of this point is of great significance to the design, manufacture and subsequent use of the vehicle, as it is directly related to the comfort and safety of the passengers. In automobile design, the position of the R point directly affects the design of the seat, including the position, angle of the seat and the size of the passenger's activity space in the vehicle, which are all designed and adjusted based on this reference point. Therefore, the setting of the R point is a very important link in the process of automobile design.

[0060] S102, calculating the rear axle load data according to the target passenger car's kerb mass, wheelbase, front axle load ratio and position information.

[0061] In the embodiments of the present application, the rear axle load data includes the load of each row of seats on the rear axle, the load of the luggage on the rear axle, and the load of the rear axle in the target passenger car in the running state.

[0062] Specifically, according to the position relationship between the front wheel center coordinates, the luggage mass center coordinates and the seating reference point coordinates of each row of seats and the corresponding mass center coordinates, the distance between the mass center of each row of seats and the front wheel and the distance between the mass center of the luggage and the front wheel are calculated; according to the wheelbase, the distance between the mass center of each row of seats and the front wheel, the load of each row of seats on the rear axle is calculated; according to the wheelbase, the distance between the mass center of the luggage and the front wheel, the load of the luggage on the rear axle is calculated.

[0063] Specifically, according to the kerb mass and the front axle load ratio in the running state, the load of the rear axle in the target passenger car in the running state is calculated.

[0064] S103, determining all load conditions of the target passenger car according to the number of each row of seats in the target passenger car.

[0065] In the embodiments of the present application, the load conditions include the number of passengers in each row of seats and the number of luggage in the target passenger car. The number of passengers in each row of seats in the load condition is less than or equal to the number of each row of seats, and the number of luggage in the load condition is less than the preset maximum number of luggage.

[0066] For example, the target passenger car is a one-row two-seat car, that is, the number of first-row seats is 2, and the maximum number of luggage is 1. Then the load conditions include (1): the number of passengers in the first row is 0, and the number of luggage is 0; (2): the number of passengers in the first row is 0, and the number of luggage is 1; (3): the number of passengers in the first row is 1, and the number of luggage is 0; (4): the number of passengers in the first row is 1, and the number of luggage is 1; (5): the number of passengers in the first row is 2, and the number of luggage is 0; (6): the number of passengers in the first row is 2, and the number of luggage is 1.

[0067] S104、According to the kerb mass, the rear axle load data, the number of passengers in each row of seats in each load condition and the number of luggage, the vehicle load in each load condition is calculated.

[0068] In the embodiments of the present application, the vehicle load in each load condition includes the load condition weight in each load condition, the load of the rear axle in each load condition, and the load of the front axle in each load condition. After the calculation is completed, the vehicle load in each load condition can also be displayed to the target user's vehicle axle load evaluation interface through the table component.

[0069] Further, the load condition with the maximum load condition weight, the load condition with the maximum load of the front axle, and the load condition with the maximum load of the rear axle can be determined from the calculated vehicle load in all load conditions. In addition, the load condition with the maximum load condition weight, the load condition with the maximum load of the front axle, and the load condition with the maximum load of the rear axle can also be displayed to the target user's vehicle axle load evaluation interface through the table component.

[0070] Here, the embodiments of the present application can determine the load condition with the maximum load condition weight, the load condition with the maximum load of the front axle, and the load condition with the maximum load of the rear axle. The load condition with the maximum load condition weight, the load condition with the maximum load of the front axle, and the load condition with the maximum load of the rear axle can be used for vehicle chassis load capacity design, vehicle performance and related parameter calculation, etc., reducing potential risks such as inability to achieve vehicle braking, handling stability and other performance, and insufficient vehicle load capacity.

[0071] Specifically, the vehicle load in each load condition is calculated according to the kerb mass, the rear axle load data, the number of passengers in each row of seats in each load condition and the number of luggage by the following steps:

[0072] Step one, the load condition weight in each load condition is calculated according to the kerb mass, the number of passengers in each row of seats in each load condition and the number of luggage.

[0073] In the embodiments of the present application, for each load condition, the kerb mass, the number of passengers in each row of seats in the load condition and the number of luggage are substituted into the following formula to calculate the load condition weight in the load condition.

[0074] M 载 = M 目标乘用车 + M 乘 *N 乘 + M 行 *N 行 ;

[0075] Wherein, M 载 is the load condition weight in the load condition, M目标乘用车 For the curb weight of the target passenger vehicle, M 乘 To pre-determine the occupant mass, N 乘 M represents the total number of occupants in all rows of seats under this load condition. 行 To preset the baggage weight, N 行 This represents the number of bags under this load condition.

[0076] Step 2: Calculate the load on the rear axle under each load condition based on the curb weight, rear axle load data, number of passengers in each row of seats and amount of luggage under each load condition.

[0077] In this embodiment of the application, the rear axle load data includes the load of each row of seats on the rear axle, the load of luggage on the rear axle, and the load of the rear axle when the target passenger vehicle is in a ready state; specifically, for each load condition, the curb weight, the rear axle load data, the number of passengers in each row of seats in the load condition, and the amount of luggage are substituted into the following formula to calculate the load condition weight under the load condition.

[0078]

[0079] Among them, M 载后 M represents the load weight under this load condition. 后 Let Q be the load on the rear axle of the target passenger vehicle in its prepared state, and let m be the number of rows of seats in the target passenger vehicle. i Let n be the load on the rear axle from the seat in the i-th row. i Let m be the number of passengers in the i-th row of seats under this load condition. 行 N represents the load of luggage on the rear axle. 行 This represents the number of bags under this load condition.

[0080] Step 3: Calculate the load on the front axle under each load condition based on the load weight and the load on the rear axle.

[0081] In this embodiment of the application, for each load condition, the load on the front axle is calculated based on the load weight and the load on the rear axle under that load condition.

[0082] M 载前 =M 载 -M 载后 ;

[0083] Among them, M 载前 M represents the load on the front axle under this load condition. 载 M represents the load weight under this load condition. 载后 This is the load weight under this load condition.

[0084] Reference Figure 2As shown, a flowchart of a vehicle axle load calculation method provided by the embodiment of the application is shown, and the exemplary steps of the embodiment of the application are described as follows.

[0085] S201, according to the position relationship between the front wheel center coordinates, the luggage centroid coordinates and the corresponding centroid coordinates of the seating reference point coordinates of each row of seats, the distance between the centroid of each row of seats and the front wheel and the distance between the centroid of the luggage and the front wheel are calculated.

[0086] In the embodiment of the application, the position relationship between the seating reference point coordinates of each row of seats and the corresponding centroid coordinates refers to the distance vector between the centroid of each row of seats and the seating reference point of each row of seats on the X-axis of the vehicle coordinate system of the target passenger vehicle; wherein the centroid coordinates of each row of seats (referring to the coordinate value of the centroid of each row of seats on the X-axis of the vehicle coordinate system) minus the seating reference point coordinates of each row of seats is equal to the distance vector between the centroid of each row of seats and the seating reference point of each row of seats; the distance vector is fixed and preset in advance.

[0087] Therefore, for each row of seats, first, the seating reference point coordinates of the row of seats are added to the distance vector between the centroid of the row of seats and the seating reference point of the row of seats to obtain the centroid coordinates of the row of seats; and then the centroid coordinates of the row of seats are subtracted from the front wheel center coordinates to obtain the distance between the centroid of each row of seats and the front wheel.

[0088] In addition, the centroid coordinates of the luggage are subtracted from the front wheel center coordinates to obtain the distance between the centroid of each row of seats and the front wheel.

[0089] S202, according to the wheelbase, the distance between the centroid of each row of seats and the front wheel, the load of each row of seats on the rear axle is calculated.

[0090] In the embodiment of the application, the wheelbase and the distance between the centroid of each row of seats and the front wheel are substituted into the following formula to calculate the load of each row of seats on the rear axle.

[0091]

[0092] wherein, m i is the load of the i-th row of seats on the rear axle, M 乘 is the preset passenger mass, X i is the distance between the centroid of the i-th row of seats and the front wheel, and L is the wheelbase.

[0093] S203, according to the wheelbase, the distance between the centroid of the luggage and the front wheel, the load of the luggage on the rear axle is calculated.

[0094] In the embodiment of the application, the wheelbase and the distance between the centroid of the luggage and the front wheel are substituted into the following formula to calculate the load of the luggage on the rear axle:

[0095]

[0096] Where, m 行 For the load of luggage on the rear axle, M 行 To preset the baggage weight, X 行 L is the distance from the center of gravity of the luggage to the front wheel, and L is the wheelbase.

[0097] S204. Based on the curb weight and the front axle load ratio in the prepared state, calculate the load on the rear axle of the target passenger vehicle in the prepared state.

[0098] In this embodiment of the application, the curb weight and the front axle load ratio in the curb condition are substituted into the following formula to calculate the load on the rear axle of the target passenger vehicle in the curb condition:

[0099] M 后 =M 目标乘用车 *(1-a);

[0100] Among them, M 后 M represents the load on the rear axle of the target passenger vehicle in its prepared state. 目标乘用车 Let 'a' represent the curb weight of the target passenger vehicle, and 'a' represent the front axle load ratio in the curb condition.

[0101] This application provides another method for calculating the axle load of a vehicle. This method can accurately calculate the rear axle load data and is used to calculate the vehicle load under various load conditions.

[0102] Based on the same inventive concept, this application also provides a vehicle axle load calculation device corresponding to the vehicle axle load calculation method.
