Joystick controlled scrubber
First Claim
1. A floor maintenance vehicle for performing floor maintenance operations comprising:
- a transaxle rear drive system and a powered steering system for controlling steering of a front wheel; and
a joystick control system for providing integrated control of the transaxle rear drive system and the powered steering system by controlling the traverse speed of the transaxle drive with respect to the steering angle such that the sharper the steering angle the lower the maximum traverse speed.

Abstract
An apparatus and method for a floor maintenance vehicle comprises a transaxle rear drive system and a powered front wheel steering system; and a joystick control system providing integrated control of the transaxle rear drive system and the powered steering system by controlling the traverse speed of the transaxle drive with respect to the steering angle such that the sharper the steering angle the lower the maximum traverse speed. A joystick control process for controlling a floor maintenance vehicle comprises receiving a turn signal to a steering control function from a joystick representing an operator desired turn angle, and outputting from the steering control function a turn angle signal; and receiving a speed signal to a traverse control function from a joystick representing an operator desired speed, and receiving the turn angle signal and outputting a transaxle speed control signal based on the speed signal and the turn angle signal.

8. A joystick control process for controlling a floor maintenance vehicle comprising the steps of:
-
receiving a turn signal to a steering control function from a joystick indicative of the joystick position representing an operator desired turn angle, and outputting from said steering control function a turn angle signal indicative of the operator desired turn angle; and receiving a speed signal to a traverse control function from a joystick indicative of the joystick position and an operator desired speed, and receiving from said traverse control function communicably linked to said steering control function the turn angle signal and outputting from said traverse control function a transaxle speed control signal based on the speed signal and the turn angle signal. - View Dependent Claims (9, 10)
