The present invention discloses an active suspension vehicle and a control method controlling the same. Each wheel of the vehicle is equipped with a telescopically adjustable active actuator. The control method begins by constructing a load and deformation joint control matrix of the vehicle and measuring the current vehicle parameters; then determining vertical displacement excitation of wheels at a next moment, and pre-calculating passive responses of vehicle height, attitude, and wheel loads at the said next moment; determining the vehicle height, attitude, and feasible wheel load expectations at the said next moment, and inverse-calculating adjustment strokes of the suspension; finally, performing active suspension adjustment to chase the vehicle height, attitude, and feasible wheel load expectations in real-time. The disclosure implements synchronous vehicle height, attitude, and wheel loads control for multi-axle vehicles, thus significantly improving their passability, maneuverability, and stability under extreme off-road terrains.
