Described herein is a method for controlling a motor-powered hatch arrangement of a motor vehicle, wherein the hatch arrangement has an upwardly deflectable hatch, in particular an upwardly pivotable hatch, a drive arrangement which is assigned to the hatch and a control arrangement which is assigned to the drive arrangement, wherein the motor-powered deflection of the hatch in the opening direction is limited to a maximum hatch deflection by means of a control arrangement. It is proposed that the chassis of the motor vehicle can be adjusted vertically as required in order to set different vehicle body levels, and in that the maximum hatch deflection is adapted to a change in the vehicle body level by means of the control arrangement.

A heavy-duty active suspension, including a suspension frame, a lifting unit, a pin axle, a through axle, two wheel-driving units, an encoder, and a displacement sensor. The lifting unit is mounted on an upper side of the suspension frame for driving a heavy-duty support platform to rise and descend. The pin axle is mounted across the suspension frame along a front-rear direction. The through axle is rotatably mounted on the pin axle through a bearing, and is across the suspension frame along a left-right direction. The two wheel-driving units are respectively mounted on both ends of the through axle. The encoder is installed on the through axle for measuring a swing angle of the through axle. The displacement sensor is installed between an output end of the lifting unit and the suspension frame. A suspension vehicle including the active suspension and a leveling control method thereof are further provided.
