Abstract EN
Vehicle dynamics are directly dependent on tire-road contact forces and torques which are themselves dependent on the wheels’ load and tire-road friction characteristics.
An acquisition of the road disturbance property is essential for the enhancement of vehicle suspension control systems.
This paper focuses on designing an adaptive real-time road profile estimation observer considering load variation via vehicle vertical dynamics.
Firstly, a road profile estimator based on a linear Kalman filter is proposed, which has great advantages on vehicle online control.
Secondly, to minimize the estimation errors, an online identification system based on the Recursive Least-Squares Estimation is applied to estimate sprung mass, which is used to refresh the system matrix of the adaptive observer to improve the road estimation efficiency.
Last, for mining road category from the estimated various road profile sequencse, a road categorizer considering road frequency and amplitude simultaneously is approached and its efficiency is validated via numerical simulations, in which the road condition is categorized into six special ranges, and this road detection strategy can provide the suspension control system with a better compromise for the vehicle ride comfort, handling, and safety performance.
