Method and system for controlling a traction motor (264) of a materials handling vehicle (10), that includes receiving steering command signals (278); generating an output value proportional to a rate of change of the steering command signals (320); determining whether the output value is greater than or equal to a predetermined threshold (324); determining a raw target steering angle value for controlling the traction motor of the materials handling vehicle; and calculating the current target steering angle value (330) based on:whether the output value is greater than or equal to a predetermined threshold (324), and whether the raw target position value is less than or equal to a previously calculated target steering angle value (322), calculating a traction setpoint based on the target steering angle value and controlling the traction motor based on the traction setpoint.
