Computes the boost force, internal angles, and areas as well as pressure drops of the VDO steering gear model.
Input:
REQ/id, FUNCTION = USER (1105 )
Request File Output
Column Number Output:
1. Power assist boost force (lbs)
2. Windup angle of valve (deg)
3. Valve are for VAPS or flow for EVO (in2/gpm)
4. First area in gear (in2)
5. Second area in gear (in2)
6. Pressure drop across piston (psi)
Notes on Input and Output
This REQUEST simply outputs data computed in the VDO steering gear model code. This routine, developed by Jon Quigley, allows a user to store steering gear model information at each time step. Note that the VDO power steering subroutine must be called in order for this REQUEST to output data. Please refer to Chapter 6 for information on the VDO power steering model.
