AI Technical Summary
Existing suspension rubber component stiffness compensation technology cannot achieve targeted closed-loop correction, resulting in a decrease in the accuracy of wheel center input force calculation, and high maintenance costs or inability to accurately locate degraded components.
The suspension rubber component stiffness compensation method based on off-center load decoupling constructs a rubber component-operating condition-stiffness influence database and safety boundary conditions, and combines the whole vehicle resultant force balance verification benchmark to diagnose and directionally compensate the stiffness of the suspension rubber components in real time. It uses the off-center load estimation results of the target vehicle and the standard sensor signals for cross-verification and stiffness parameter correction.
It realizes online automatic diagnosis and directional closed-loop compensation of suspension rubber component stiffness, improves the real-time performance and accuracy of rubber component stiffness compensation, and overcomes the problem of decreased accuracy of wheel center input force calculation due to aging.
