AVSE Ackerman Statistics

This routine computes the percent Ackerman and Ackerman error associated with a given suspension design. The wheel toe angles and ideal inside wheel turn are also calculated.
Input:
REQ/id, FUNCTION = USER (1125,m9lid,m9rid,m11lid,m11rid,xaxle)
where:
 
 
Description
m9lid
=
id of MARKER at point 9 (wheel center) on left side
m9rid
=
id of MARKER at point 9 (wheel center) on right side
m11lid
=
id of MARKER at point 11 (spindle alignment) on left side
m11rid
=
id of MARKER at point 11 (spindle alignment) on right side
xaxle
=
X coordinate of rear axle rear center
Request File Output
Column Number Output:
1. Percent Ackerman (%)
2. Ackerman deviation of outside wheel (deg)
3. Left toe angle (deg)
4. Right toe angle (deg)
5. Ideal steer angle of outside wheel (deg)
6. (not used)
Notes on Input and Output
All Ackerman calculations are based on inside wheel turn angle and is similar to REQUEST 60 with method flag set to 0.
