Abstract: Systems and methods can prevent or reduce jerk during operation of a materials-handling vehicle that is unloaded or carrying a load. The vehicle comprises one or more user input devices configured to receive from an operator a request to perform an action and a processor. The processor is configured to determine, before performing the action requested by the operator, a force acting on the load carried by the materials-handling vehicle as a result of the action requested by the operator. The processor determines whether the force would result in a jerk if the action is performed as requested. If it is determined that the force would result in a jerk, the action is modified so as to reduce the force. If it is determined that the force would not result in a jerk, the materials-handling vehicle performs the action as requested by the operator without modification to reduce the force.
