Dynamics of the Automobile Related to Driver Control 680194

Automobile dynamics related to closed-loop control by the driver are presented. This includes developing the equations of motion; linearizing the 4 deg of freedom set for roll angle, lateral velocity, yaw rate, and axial velocity; and deriving the steer angle transfer functions. A compendium of dynamic data for United States style automobiles is given. Example transfer functions for a typical sedan, circa 1965, are computed. Literal approximate factors for the lateral transfer functions in both 2 and 3 deg of freedom are derived and tabulated.
