摘要： A materials handling vehicle is provided comprising: a frame; wheels supported on the frame; a traction motor coupled to one of the wheels to effect rotation of the one wheel; a speed control element operable by an operator to define a speed control signal corresponding to a desired speed of the traction motor; a system associated with a steerable wheel to effect angular movement of the steerable wheel; and control apparatus coupled to the speed control element to receive the speed control signal, and coupled to the traction motor to generate a drive signal to the traction motor in response to the speed control signal to control the operation of the traction motor. The control apparatus may determine an acceleration value for the traction motor based on at least one of an angular position of the steerable wheel, a speed of the traction motor and a current position of the speed control element as defined by the speed control signal.

摘要： Electrical steering assist systems reduce the operator applied steering effort necessary to operate material handling vehicles. A steer drive unit including a motor is coupled to a steerable wheel for providing steering assist. The amount of steering assist provided by the steer drive unit is determined by a controller that receives input from one or more input sensing devices. The input sensing device(s) may include force sensors that detect an operator applied turning force. The input sensing device(s) may also detect the movement of one steering component relative to another. Further, the input sensing device(s) may include operator activated controls such as a joystick, potentiometer, switches and voice initiated commands. Input sensing device(s) may additionally be provided to detect operational parameters such as the load on the material handling vehicle, vehicle speed, or environmental conditions such as travel path obstruction detection, homing and proximity sensing.
