Adaptive　active　suspension　systems,　integral　to　specialized　vehicles,　hold　significance　for　their　stability　and　safety.　This　study　introduces　a　novel　adaptive　active　suspension　system　featuring　four　independently　controlled　wheels　employing　wheel-hub　motors,　hydraulic　cylinders,　pump　motor　power,　controllers,　and　sensors.　A　rapid　and,　within　a　certain　range,　leveling　and　height　adjustment　control　strategy　is　proposed　for　this　system,　utilizing　the　Kalman　filter　algorithm.　Additionally,　the　paper　examines　the　front-wheel　Ackermann　steering　model　and　four-wheel　reverse　Ackermann　transition　model　to　enhance　the　suspension＇s　stability.　Subsequently,　experiments　on　leveling　and　height　adjustment　are　conducted,　demonstrating　the　system＇s　capability　to　swiftly　and　accurately　rectify　the　vehicle＇s　deviation　angle　within　the　specified　threshold.　Following　adjustments　made　by　the　leveling　and　height　control　algorithm,　the　vehicle　body　promptly　returns　to　the　preset　level　state　and　designated　height.　The　leveling　control　system　holds　broad　applicability　in　intelligent　agriculture,　logistics　handling,　off-road　equipment,　and　other　domains,　presenting　significant　practical　utility.
