A tractor simulator is being developed at the University of Manitoba and it is necessary to determine appropriate steering torque feedback that will promote driver control. An experiment was conducted with ten subjects to determine how constant torques of 0, 2, 5, and 10 Nm would affect driving performance in a tractor simulator. When no torque feedback was applied to the steering column, subjects had difficulty following a prescribed path and had a large lateral error. As steering torque was increased, subjects tended to have more control and were able to follow the prescribed path with more precision. The experimental evidence suggests that a constant steering torque of 10 Nm is appropriate to promote driver control in a simulator environment.
