    摘要: A work vehicle includes a pair of electric motors independently running and driving right and left running wheels in a state of being able to create straight running state and turning running; a pair of right and left change speed operation tools independently manually operated and performing a change speed operation to the right and left running wheels; and a controller controlling operation. The controller controls the operation of the respective electric motors by setting target speeds with regard to the respective electric motors such that the speed difference in the target speeds is smaller than the speed difference corresponding to the difference in the operation positions of the respective change speed operation tools by a set amount in a case where the operation positions of the respective change speed operation tools are different between right and left.

    摘要: An apparatus and method for a floor maintenance vehicle for performing floor maintenance operations, which comprises 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. The invention incorporates a joystick control process for controlling a floor maintenance vehicle, which comprises 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.

    摘要: A steering mechanism that controls a drive and steer transmission and that causes the transmission to execute turns in the direction a steering wheel is turned when operating in either the forward or reverse direction of travel. In response to operator engagement of a drive control, an actuation linkage shifts an elongate member within a slot formed in a cam member that pivots in response to turning of a steering wheel. Shifting of the rod member between two positions on either side of the cam member pivot axis causes the drive and steer transmission to steer the vehicle in the desired direction when the vehicle is traveling in both forward and reverse.

    摘要: A system, method, and computer program product for detecting and compensating for a traction steer event is provided. A first wheel speed of a first driven wheel is compared with a second wheel speed of a second driven wheel to determine whether a wheel slip condition has occurred. If a wheel slip condition is determined to have occurred, a current operating state of a vehicle is compared to an expected operating state of the vehicle to determine if a traction steer event has occurred. If a traction steer event is determined to have occurred, brake pressure is selectively applied to the first or second driven wheel to compensate for the traction steer event.
