The application provides a detection method of a suspension system and a vehicle, and relates to the technical field of vehicle chassis. After a first control action is performed, a force deviation value is determined, which can determine the deviation degree of the actual feedback force when following the first target demand force. The actual feedback force greater than the preset force indicates that the suspension system has output a large part of the active force, but the force has not been fully realized. The force deviation value in the preset deviation range indicates that the actual feedback force is close to the first target demand force, the suspension system has entered an effective force applying stage, the establishment process of the active force is normal, but it has not reached a saturated state. In combination with the above multi-dimensional conditions, it can be determined that the execution component is working, the establishment process of the active force is normal, but the force has not been fully realized, and it can be concluded that the hydraulic pipeline has been blocked. The related technology only relies on the relative height without change, and cannot distinguish the influence caused by the height sensor fault. Therefore, the method can accurately detect the pipeline of the suspension system.

A robot manipulator has a base with a connected arm by a shoulder joint, and a control system and force selector. Based on a target trajectory for a distal end of the arm instructions, a target motion and an effective force applied to the base that causes the base to execute the target motion is determined. An applied force on the robot manipulator results in a determination of a virtual ZMP force applied to the base that would either counteract an observed motion of a ZMP of the robot manipulator or act to move the ZMP back to within a predetermined support region, and / or an external force applied. Data defining the effective force and the virtual ZMP force and / or the external force applied to the base and determines a target force based on the data is received. The base executed a motion in response to the target force.
