Embodiment Construction

[0007] see figure 1 , the vehicle attitude control method provided by the embodiment of the present invention includes the following steps:

[0008] Step 1. Obtain the low-end compensation height values ​​of the left and right support points required for vehicle leveling according to the X-direction value of the inclination sensor, and obtain the low-end compensation height values ​​of the front and rear support points required for vehicle leveling according to the Y-direction value of the inclination sensor.

[0009] Step 2, the low-end compensation height values ​​of the left and right support points and the low-end compensation height values ​​of the front and rear support points are superimposed to form the compensation height values ​​of the front, rear, left, and right support points, and the compensation height values ​​of the front, rear, left, and right support points are added to their respective The current height value of the support point is used to obtain the fin...

Abstract

The invention discloses a vehicle attitude control method. The control method comprises the following steps: obtaining a height value needed by vehicle minimum attitude leveling according to a supporting point compensation height algorithm; when the maximum value of the height values of a front supporting point, a rear supporting point, a left supporting point and a right supporting point is greater than the maximum stroke of a suspension rack, carrying out leveling broadening bias iterative calculation; calculating a supporting point compensation height according to a result obtained by the leveling broaden bias iterative calculation; leveling according to a result obtained by the calculation of the supporting point compensation height. The method can be used for estimating vehicle body attitude leveling.

Description

technical field [0001] The invention relates to the technical field of vehicle attitude leveling, in particular to a vehicle attitude control method Background technique [0002] In the prior art, there is no related technology about the body attitude leveling prediction algorithm. There are only technologies such as the rapid leveling system of the vehicle body. Most of the leveling algorithms use the inclination sensor as the basis for real-time feedback leveling control of the vehicle body posture. A few use the current value of the vehicle body posture as a reference to calculate the height value of the support point that needs to be compensated for direct leveling. , all cannot be estimated and calculated, and can only be judged according to the inclination sensor after leveling whether it can meet the use requirements. Contents of the invention [0003] The invention provides a vehicle attitude control method, which solves or partially solves the technical problem i...
