1. A materials handling vehicle comprising:

  • a frame;

    wheels supported on said frame;

    a traction motor coupled to one of said wheels to effect rotation of said one wheel;

    a speed control element operable by an operator to define a speed control signal corresponding to a desired speed of said traction motor;

    a system associated with a steerable wheel to effect angular movement of said steerable wheel;

    control apparatus coupled to said speed control element to receive said speed control signal, and coupled to said traction motor to generate a drive signal to said traction motor in response to said speed control signal to control the operation of said traction motor;

    said control apparatus storing at least one acceleration value for said traction motor defining a rate of acceleration for said traction motor; and

    said control apparatus determining at least one acceleration reduction factor based on at least one of an angular position of said steerable wheel and a speed of said traction motor.
