Embodiment Construction

[0018] see figure 1 According to an embodiment of the present invention, a vehicle body attitude estimation and leveling control method includes the following steps:

[0019] 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.

[0020] 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...

Abstract

The invention discloses a leveling estimating control method for postures of an automobile body and belongs to the technical field of leveling of the postures of automobiles. The leveling estimating control method for the postures of the automobile body includes the following steps that height values needed by leveling of the lowest posture of a whole automobile are obtained according to a supporting point compensation height algorithm; and when the maximum value of the front supporting point height value, the rear supporting point height value, the left supporting point height value and the right supporting point height value is larger than the maximum stroke of a suspension, leveling extension deviation iteration calculation is conducted, supporting point compensation height calculation is conducted according to a result obtained through leveling extension deviation iteration calculation, and leveling is conducted according to a result obtained through supporting point compensation height calculation. According to the leveling estimating control method for the postures of the automobile body, leveling of the postures of the automobile body can be estimated.

Description

technical field [0001] The invention relates to the technical field of vehicle attitude leveling, in particular to a control method for vehicle body attitude estimation leveling 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 body attitude estimation and leveling control method...
