Tactile Feedback for Joystick Position/Speed Controls

摘要

A joystick controller is disclosed for controlling movement of a boom lift platform, the controller having actuators or the like that provide one or more forms of tactile feedback that are intuitively interpreted and adjusted by the user of the joystick motion control, the joystick being neutrally-biased to effect a null movement when the joystick is positioned in a neutral position, but also being adapted with at least one form of tactile feedback by which the joystick controller conveys information about the boom lift's operation to the joystick operator, such as through resistive force or through vibrations or the like.

主权项

1. A motion control system for controlling the movement of a hydraulically powered implement relative to a physical reference, said motion control system comprising:
a) a joystick controller having a joystick handle for manually controlling movement of the powered implement relative to said physical reference; b) said joystick handle being connected to said joystick controller; c) a motion monitoring system associated with sensors to monitor the position of said powered implement relative to said physical reference; d) said position motion monitoring system being configured to generate a signal indicative of actual motion of said powered implement relative to said physical reference; e) a handle position controller being configured to receive said signal indicative of the actual motion of said powered implement relative to said physical reference, and said handle position controller further being configured to influence the position of said joystick handle in relation to said signal; and f) said handle position controller further being configured to influence said joystick handle to be closer to a first extent in a first direction than a neutral position if the actual motion of said powered implement relative to said physical reference is closer to a first movement than a null movement.
