REDUCED DEAD BAND FOR SINGLE JOYSTICK DRIVE VEHICLE CONTROL

摘要

A system and a method for controlling a vehicle with a joystick that includes implementing at least one dead band for the joystick. The dead band prevents movement of the vehicle when the joystick is within the dead band areas. The dead band areas are adjustable and take a plurality of shapes including having gaps between areas of the dead band areas. These dead bands allow for smooth operation of a vehicle by suppressing the control signal of the joystick for unintentional movements of the joystick by the operator. The adjustability of the dead band allows for adjustment based on the joystick type, the vehicle type, and the control desired.

主权项

1. A system for controlling a vehicle comprising:
a joystick including a base and a joystick handle movable relative to the base, the joystick configured to output a position signal indicative of an X-axis position of the joystick handle relative to an X-axis origin position and a Y-axis position of the joystick handle relative to a Y-axis origin position; and a controller electronically coupleable to the joystick and configured to
receive the position signal from the joystick,determine an X-axis dead band width based on the Y-axis position of the joystick handle,determine whether the X-axis position of the joystick handle is within the determined X-axis dead band width,operate the vehicle based on the X-axis position when the X-axis position of the joystick handle is outside of the determined X-axis dead band width, andoperate the vehicle based on an X-axis position equal to an X-axis dead band default value when the X-axis position of the joystick handle is within the determined X-axis dead band width.
