It is to be understood that the specific embodiments described herein are only used to explain the relevant application, rather than to limit the application. It is also necessary to explain that, for ease of description, only the parts related to the application are shown in the drawings.

[0041] It should be noted that, in the absence of conflict, the embodiments of the present application, that is, the features of the embodiments, can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0042] The following describes in detail the vehicle weight calculation method, system, vehicle and device according to the embodiments of the present application in conjunction with the accompanying drawings.

[0043] Figure 1 FIG. 1 is a flow chart of a method for calculating vehicle weight according to an embodiment of the present application. Figure 1 As shown, the vehicle weight calculation method according to the embodiment of the present application includes the following steps:

[0044] S101: Obtaining the airbag pressure of each air suspension in a vehicle, wherein the vehicle is a vehicle equipped with an air suspension.

[0045] In one embodiment of the present application, obtaining the airbag pressure of each air suspension in the vehicle includes: obtaining the airbag pressure of each air suspension by detecting according to a pressure sensor pre-assembled on the airbag of each air suspension.

[0046] S102: Obtain the cross-sectional diameter of the airbag.

[0047] In one embodiment of the present application, obtaining the cross-sectional diameter of the airbag includes: obtaining an airbag model; and obtaining the cross-sectional diameter of the airbag according to the airbag model.

[0048] S103: Obtaining the bearing mass of each airbag according to the cross-sectional diameter of the airbag and the airbag pressure of each air suspension.

[0049] In one embodiment of the present application, the bearing mass of each airbag is obtained according to the cross-sectional diameter of the airbag and the airbag pressure of each air suspension, including: obtaining a bearing mass calculation formula, and obtaining the bearing mass of each airbag according to the bearing mass calculation formula, wherein the calculation formula is:

[0050] m 气囊x =3.14*(d / 2) 2 P / 9.8

[0051] Among them, the m 气囊x is the load mass on the airbag x, d is the cross-sectional diameter of the airbag, and P is the airbag pressure.

[0052] S104: Obtain the total mass of the vehicle according to the bearing mass of each airbag and the mass under the airbag.

[0053] In a specific example, the total mass of the vehicle is obtained based on the bearing mass of each airbag and the mass under the airbag, including: summing the bearing mass of each airbag to obtain the total mass above the airbag; obtaining the mass under the airbag; summing the total mass above the airbag and the mass under the airbag to obtain the total mass of the vehicle.

[0054] In this example, obtaining the mass under the airbag includes: obtaining vehicle type information; and obtaining the mass under the airbag according to the vehicle type information. Generally speaking, after a vehicle type is determined, there is a corresponding mass under the airbag.

[0055] Specifically, pre-assemble an independent pressure sensor on each air suspension airbag, and then perform the following steps:

[0056] 1. Obtain the airbag pressure P through the pressure sensor;

[0057] 2. The cross-sectional diameter of the airbag is obtained by the airbag model as d;

[0058] 3. The load mass m on a single airbag is calculated by the cross-sectional diameter of the airbag and the airbag pressure. 气囊x =3.14*(d / 2) 2 P / 9.8;

[0059] 4. Total mass of the airbag m 上 =m 气囊1 +m 气囊2 +m 气囊3 +m 气囊4 +... (determined by the number of air sacs);

[0060] 5. The mass under the airbag is a fixed value m for the same model of vehicle 下 ;

[0061] 6. Then the total mass of the vehicle is m = m 上 +m 下 .

[0062] It should be noted that the airbag pressure will be unstable due to vehicle bumps during driving, resulting in large errors in the calculation of the airbag bearing mass. However, the total weight of the vehicle will basically not change during driving. In view of this situation, the vehicle weight calculation is only performed when the vehicle is stationary, and the value is locked during vehicle operation and is not calculated and updated. This further improves the calculation accuracy.

[0063] For example: a 6×4 dump truck, with a mass m under the airbag 下 =4000kg, the front suspension is a single-bridge two-airbag suspension, and the cross-sectional diameter of the airbag is d 1 =0.2m, the middle bridge and rear bridge are single-bridge four-airbag suspension, the cross-sectional diameter of the airbag is d 2=0.32. The pressures of the two air bags of the front suspension are P 1 , P 2 The pressures of the eight air bags in the rear suspension are P 3 , P 4 , P 5 , P 6 , P 7 , P 8 , P 9 , P 10 .

[0064] The mass of each airbag is:

[0065] m 气囊1 =3.14*(d 1 / 2) 2 *P 1 / 9.8=0.0032P 2

[0066] m 气囊2 =3.14*(d 1 / 2) 2 *P 2 / 9.8=0.0032P 2

[0067] m 气囊3 =3.14*(d 2 / 2) 2 *P 3 / 9.8=0.0082P 3

[0068] m 气囊4 =3.14*(d 2 / 2) 2 *P 4 / 9.8=0.0082P 4

[0069] m 气囊5 =3.14*(d 2 / 2) 2 *P 5 / 9.8=0.0082P 5

[0070] m 气囊6 =3.14*(d 2 / 2) 2 *P 6 / 9.8=0.0082P 6

[0071] m 气囊7 =3.14*(d 2 / 2) 2 *P7 / 9.8=0.0082P 7

[0072] m 气囊8 =3.14*(d 2 / 2) 2 *P 8 / 9.8=0.0082P 8

[0073] m 气囊9 =3.14*(d 2 / 2) 2 *P 9 / 9.8=0.0082P 9

[0074] m 气囊10 =3.14*(d 2 / 2) 2 *P 10 / 9.8=0.0082P 10

[0075] The total mass of the airbag is:

[0076] m 上 =m 气囊1 +m 气囊2 +m 气囊3 +m 气囊4 +m 气囊5 +m 气囊6 +m 气囊7 +m 气囊8 +m

[0077] 气囊9 +m 气囊10

[0078] =0.0032P 1 +0.0032P 2 +0.0082P 3 +0.0082P 4 +0.0082P 5 +0.0082P 6 +0.0082P 7 +0.0082P 8 +0.0082P 9 +0.0082P 10 .

[0079] The total mass of the vehicle is:

[0080] m=m 上 +m 下

[0081] =0.0032P1 +0.0032P 2 +0.0082P 3 +0.0082P 4 +0.0082P 5 +0.0082P 6 +0.0082P 7 +0.0082P 8 +0.0082P 9 +0.0082P 10 +4000.

[0082] Among them, the P value changes in real time with the vehicle load and is collected through a pressure sensor.

[0083] According to the vehicle weight calculation method of the embodiment of the present application, the airbag pressure of each air suspension in the vehicle is obtained, and then the bearing mass of each airbag is obtained according to the cross-sectional diameter of the airbag and the airbag pressure of each air suspension, and finally, the total vehicle mass is obtained according to the bearing mass of each airbag and the mass under the airbag. The problem of low success rate and poor accuracy in calculating the total vehicle mass in the prior art is effectively solved, and the success rate and accuracy of vehicle weight calculation can be effectively improved.

[0084] In practical applications, by accurately calculating the vehicle weight, the stability of the vehicle's accelerator pedal response curve and the brake pedal response curve can be greatly improved, thereby improving the vehicle's driving experience. In addition, it can effectively avoid the occurrence of overloading and improve the driving safety of the entire vehicle.

[0096] In this example, obtaining the mass under the airbag includes: obtaining vehicle model information; and obtaining the mass under the airbag according to the vehicle model information.

[0097] Specifically, pre-assemble an independent pressure sensor on each air suspension airbag, and then perform the following steps:

[0098] 1. Obtain the airbag pressure P through the pressure sensor;

[0099] 2. The cross-sectional diameter of the airbag is obtained by the airbag model as d;

[0100] 3. The load mass m on a single airbag is calculated by the cross-sectional diameter of the airbag and the airbag pressure. 气囊x =3.14*(d / 2) 2 P / 9.8;

[0101] 4. Total mass of the airbag m 上 =m 气囊1 +m 气囊2 +m 气囊3 +m 气囊4 +... (determined by the number of air sacs);

[0102] 5. The mass under the airbag is a fixed value m for the same model of vehicle 下 ;

[0103] 6. Then the total mass of the vehicle is m = m 上 +m 下 .

[0104] It should be noted that the airbag pressure will be unstable due to vehicle bumps during driving, resulting in large errors in the calculation of the airbag bearing mass. However, the total weight of the vehicle will basically not change during driving. In view of this situation, the vehicle weight calculation is only performed when the vehicle is stationary, and the value is locked during vehicle operation and is not calculated and updated. This further improves the calculation accuracy.
