AI Technical Summary
Technical Problem
In existing technologies, the suspension damping adjustment is not precise enough, resulting in poor vehicle vibration and ride comfort, and unsatisfactory control.
Method used
By collecting vehicle motion state data, the suspension motion state is calculated based on the vehicle operation state data, and the target damping range is determined in the preset damping segment interval. The target damping coefficient is determined by using the linear damping coefficient model and the suspension motion state, so as to achieve precise adjustment of the suspension.
Benefits of technology
It achieves precise adjustment of suspension damping, with continuous and smooth damping output, significantly reducing vehicle vibration and improving ride comfort and handling stability.
