    摘要： A materials handling vehicle automatically applies a steer correction maneuver if an object is detected in a steer bumper zone in front of the vehicle. A controller detects whether an object is in front of the materials handling vehicle and automatically determines whether a steer correction maneuver should be to the right or left of the traveling direction of the materials handling vehicle. The materials handling vehicle automatically steer corrects the vehicle, e.g., at a determined steer angle that is opposite the direction to the detected position of the object, and accumulates the distance traveled by vehicle while steer correction is being performed. The vehicle then automatically counter steers the vehicle, e.g., by a determined steer amount, in the opposite direction as the steer correction for a percentage of accumulated steer distance traveled. After performing the counter steer maneuver, the vehicle may, for example, resume a substantially straight heading.

    摘要： A materials handling vehicle is provided comprising: a frame; a set of wheels supported on the frame to allow the materials handling vehicle to move across a floor surface; a rider compartment located within the frame for receiving an operator; and an operator support assembly. The operator support assembly comprises a suspended floorboard upon which the operator may stand when located within the rider compartment and an energy absorbing structure coupled to the frame and the suspended floorboard for absorbing and dissipating at least a portion of energy resulting from disturbances encountered by the vehicle as it moves across the floor surface prior to the energy portion reaching the operator standing on the suspended floorboard, the energy absorbing structure including a damping element for effecting a dampening function.

    摘要： A materials handling vehicle is provided comprising: a frame comprising an operator's compartment; wheels supported on the frame, at least one of the wheels being a steerable wheel; a steer-by-wire system associated with the steerable wheel to effect angular movement of the steerable wheel about a first axis; and a control apparatus. The steer-by-wire system comprises a control handle capable of being moved by an operator to generate a steer control signal, a selection switch capable of generating one of a first select signal and a second select signal, and a steer motor coupled to the steerable wheel to effect angular movement of the steerable wheel about the first axis. The control apparatus may be coupled to the control handle to receive the steer control signal, coupled to the selection switch to receive the one select signal, and coupled to the steer motor to generate a first drive signal to the steer motor to effect angular movement of the steerable wheel about the first axis. The control apparatus may convert the steer control signal to a corresponding desired angular position for the steerable wheel using one of first and second steerable-wheel-to-control-handle-position ratios, wherein the one ratio is selected based on the one select signal.
