[0045] A method for calculating the axle load of a whole vehicle provided in an embodiment of the present application is described in detail below.

[0046] Reference Figure 1 As shown, it is a flow chart of a method for calculating the axle load of a whole vehicle provided in an embodiment of the present application. The specific execution process of the method for calculating the axle load of the whole vehicle is as follows:

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

[0048] S102: Calculate rear axle load data according to the curb weight, wheelbase, front axle load ratio in a curb state, and position information of the target passenger vehicle.

[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, calculating the vehicle load under each load condition according to the curb weight, rear axle load data, the number of passengers in each row of seats under each load condition, and the amount of luggage.

[0051] The embodiment of the present application provides a method for calculating the axle load of a whole vehicle, the method comprising: in response to a request for a whole vehicle axle load assessment initiated by a target user in a whole vehicle axle load assessment interface, obtaining the number of seats in each row, curb weight, wheelbase, front axle load ratio in the ready state, and position information of the target passenger car input by the target user in the whole vehicle axle load assessment interface; calculating the rear axle load data according to the curb weight, wheelbase, front axle load ratio in the ready state, and 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 under each load condition according to the curb weight, rear axle load data, the number of passengers in each row of seats in each load condition, and the amount of luggage. Through the method of the present application, the vehicle load under multiple load conditions can be calculated.

[0052] The following is a description of the exemplary steps of the present application embodiment:

[0053] S101. In response to a vehicle axle load assessment request initiated by a target user in a vehicle axle load assessment interface, the number of seats in each row, curb weight, wheelbase, front axle load ratio in a curb state, and position information of a target passenger vehicle input by the target user in the vehicle axle load assessment interface are obtained.

[0054] In the implementation mode of the present application, Matlab2022b and above environment is obtained, and the vehicle axle load evaluation interface executed is built 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, the curb weight field, the wheelbase field, the front axle load ratio field in the ready state, and the position information field.

[0055] The target user enters the number of seats in each row, curb mass, wheelbase, axle load ratio in the ready state and position information of the target passenger car in the vehicle axle load assessment interface for the number of seats in each row, curb mass, wheelbase, axle load ratio in the ready state and position information fields of the target passenger car. Then, after the target user clicks the calculate button, a response is made, i.e., a vehicle axle load assessment request initiated by the target user in the vehicle axle load assessment interface is obtained to obtain the number of seats in each row, curb mass, wheelbase, axle load ratio in the ready state and position information of the target passenger car entered by the target user in the vehicle axle load assessment interface.

[0056] Among them, the target passenger car includes two axles. Curb mass refers to the weight of the car before normal driving, that is, the empty weight. Wheelbase refers to the distance from the center of the front axle to the center of the rear axle. The front axle load ratio in the ready state refers to the ratio of the weight borne by the front axle to the total weight of the target passenger car when the target passenger car is in the ready state (that is, the state without passengers or goods). The position information includes the coordinates of the center of the front wheel, the coordinates of the seating reference points of each row of seats, and the coordinates of the center of mass of the luggage; the embodiment of the present application takes the midpoint of the line connecting the rearmost point of the target passenger car and the center of mass of the rear wheel as the center of mass of the luggage.

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

[0058] Among them, in the vehicle coordinate system (also called the vehicle coordinate system), the direction is determined based on the driver's perspective. This coordinate system follows the ISO8855 / DIN70000 standard to ensure consistency in different vehicles and scenes. Specifically, the X-axis represents the longitudinal direction of the vehicle. 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 direction of the vehicle's forward movement. The Y-axis is the lateral direction, which is located on the same plane as the X-axis and is perpendicular to the X-axis and points 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 riding reference point is the design reference point during design, also known as the R point, which represents a specific position in the vehicle design, namely the "riding reference point". This concept is particularly important in automobile design. It refers to the design H point specified by the manufacturer, which is the reference position of the passenger when sitting in the car. The establishment of this point is of great significance to the design, manufacturing and subsequent use of the car, because 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 and angle of the seat and the size of the passenger's activity space in the car, 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 automobile design process.

[0060] S102: Calculate rear axle load data according to the curb weight, wheelbase, front axle load ratio in a curb state, and position information of the target passenger vehicle.

[0061] In the embodiment of the present 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 car is in a ready state.

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

[0063] Specifically, the load on the rear axle when the target passenger vehicle is in the unmanned state is calculated according to the curb weight and the front axle load ratio in the unmanned state.

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

[0065] In the implementation manner of the present application, the load condition includes the number of passengers in each row of seats and the amount 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 seats in each row, and the amount of luggage in the load condition is less than the preset maximum amount of luggage.

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

[0067] S104, calculating the vehicle load under each load condition according to the curb weight, rear axle load data, the number of passengers in each row of seats under each load condition, and the amount of luggage.

[0068] In the implementation manner of the present application, the vehicle load under each load condition includes the load condition weight under each load condition, the load of the rear axle under each load condition, and the load of the front axle under each load condition; after the calculation is completed, the vehicle load under each load condition can also be displayed in the vehicle axle load evaluation interface of the target user through a table component.

[0069] Furthermore, the load condition with the largest load condition weight, the load condition with the largest load on the front axle, and the load condition with the largest load on the rear axle can be determined from the calculated vehicle loads under all load conditions. In addition, the load condition with the largest load condition weight, the load condition with the largest load on the front axle, and the load condition with the largest load on the rear axle can be displayed in the vehicle axle load evaluation interface of the target user through a table component.

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

[0071] Specifically, the vehicle load under each load condition is calculated according to the curb weight, rear axle load data, the number of passengers in each row of seats in each load condition, and the amount of luggage through the following steps:

[0072] Step 1: Calculate the load condition weight under each load condition based on the curb weight, the number of passengers in each row of seats in each load condition, and the amount of luggage.

[0073] In the embodiment of the present application, for each load condition, the curb weight, 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;

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

[0075] Among them, M 载 is the load case weight under this load case, M目标乘用车 is the curb weight of the target passenger car, M 乘 is the preset occupant mass, N 乘 is the total number of passengers in all rows of seats in this load case, M 行 is the preset baggage mass, N 行 is the number of luggage under this load condition.

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

[0077] In the embodiment of the present 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 car 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 is the load case weight under this load case, M 后 is the load on the rear axle of the target passenger car in the ready state, Q is the number of rows of seats in the target passenger car, m i is the load of the seats in the i-th row on the rear axle, n i is the number of passengers in the i-th row of seats in this load condition, m 行 is the load of luggage on the rear axle, N 行 is the number of luggage under this load condition.

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

[0081] In the embodiment of the present application, for each load condition, the load condition weight under the load condition and the load of the rear axle are used to calculate the load of the front axle under the load condition;

[0082] M 载前 =M 载 -M 载后 ;

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

[0084] Reference Figure 2As shown, it is a flow chart of a method for calculating the axle load of a whole vehicle provided in an embodiment of the present application. The exemplary steps of the embodiment of the present application are described below:

[0085] S201. Calculate the distance between the center of mass of each row of seats and the front wheel and the distance between the center of mass of the luggage and the front wheel based on the front wheel center coordinates, the center of mass coordinates of the luggage, and the positional relationship between the seating reference point coordinates of each row of seats and the corresponding center of mass coordinates.

[0086] In the implementation manner of the present application, the positional relationship between the sitting reference point coordinates of each row of seats and the corresponding center of mass coordinates refers to the distance vector from the center of mass of each row of seats to the sitting reference point of each row of seats on the X-axis of the vehicle coordinate system of the target passenger vehicle; wherein, the center of mass coordinates of each row of seats (referring to the coordinate value of the center of mass of each row of seats on the X-axis of the vehicle coordinate system) minus the sitting reference point coordinates of each row of seats is equal to the distance vector from the center of mass of each row of seats to the sitting reference point of each row of seats; this distance vector is fixed and preset in advance.

[0087] Therefore, for each row of seats, first add the coordinates of the sitting reference point of the row of seats to the distance vector from the center of mass of the row of seats to the sitting reference point of the row of seats to obtain the center of mass coordinates of the row of seats; then subtract the front wheel center coordinates from the center of mass coordinates of the row of seats to obtain the distance between the center of mass of each row of seats and the front wheel.

[0088] In addition, the distance between the center of mass of each row of seats and the front wheel is obtained by subtracting the center of mass coordinates of the front wheel from the center of mass coordinates of the luggage.

[0089] S202. Calculate the load of each row of seats on the rear axle according to the wheelbase and the distance between the center of mass of each row of seats and the front wheels.

[0090] In the implementation mode of the present application, the wheelbase and the distance between the center of mass 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] Among them, m i is the load of the i-th row of seats on the rear axle, M 乘 is the preset occupant mass, X i is the distance from the center of mass of the i-th row of seats to the front wheels, and L is the wheelbase.

[0093] S203: Calculate the load of the luggage on the rear axle according to the wheelbase and the distance between the center of mass of the luggage and the front wheels.

[0094] In the implementation manner of the present application, the wheelbase and the distance between the center of mass 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] Among them, m 行 is the load of luggage on the rear axle, M 行 is the preset baggage mass, X 行 is the distance between the center of mass of the luggage and the front wheels, and L is the wheelbase.

[0097] S204: Calculate the load on the rear axle of the target passenger vehicle in the unloaded state according to the unloaded mass and the front axle load ratio in the unloaded state.

[0098] In the implementation manner of the present application, the curb weight and the front axle load ratio in the ready state are substituted into the following formula to calculate the load on the rear axle in the ready state of the target passenger car:

[0099] M 后 =M 目标乘用车 *(1-a);

[0100] Among them, M 后 is the load on the rear axle of the target passenger car in the ready state, M 目标乘用车 is the curb weight of the target passenger car, and a is the front axle load ratio in the curb state.

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

[0102] Based on the same inventive concept, an embodiment of the present application also provides a device for calculating the axle load of a whole vehicle corresponding to the method for calculating the axle load of a whole vehicle. Since the principle of solving the problem by the device in the embodiment of the present application is similar to the method for calculating the axle load of a whole vehicle in the embodiment of the present application, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be repeated.
