Simplified automobile steering dynamics for driver control. Prepared for SAE Aerospace Control and guidance Systems Committee Meeting, Palo Alto, March, 19-21, 1975.

Simplified equations which provide an adequate approximation of the range of possible vehicle motions, with attention focussed on constant speed tasks which do not demand near-limit performance of the car and with the car assumed to be very stiff in roll, are developed from a more complex mathematical description of the vehicle. The development of these simple equations leads to transfer functions which can be used in conjunction with driver describing functions to study the driver/vehicle system.
