Abstract
A system and method for limiting the motion of the motion platform of a vehicle simulator in which the motion platform is supported on a plurality of extensible members, the extension of the members being controlled by commands initiated by a user of the simulator. At least one absolute limit is set for at least one parameter such as position or velocity of the extension of each of the members, and the parameter is maintained within the limit. The commanded or actual magnitude of the parameter is monitored for each member relative to that members absolute limit, the member for which the monitored relative magnitude is the greatest is determined, and the limit determined for each of the other members is scaled down such that a movement of the motion platform which causes the parameter for any one member to reach its absolute limit also causes each of the other members to reach its scaled down limit at the same time.
