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.
