Toe Angle
The angle between the longitudinal axis of the vehicle and the line of intersection of the wheel plane and the road surface. Toe angle is reported in degrees, and is positive if the wheel front is rotated in towards the vehicle body.
Computed by:
SVCGAN
Input Variables Used:
■Wheel center marker identifiers (idwcfl, idwcfr, idwcrl, idwcrr)
■Global origin marker identifier (gblm)
Method:
SVC uses the INFO utility subroutine to retrieve the Euler angles of the wheel center marker with respect to the global marker. SVC forms the direction cosine matrix of the wheel center marker with respect to the global marker from the Euler angles. SVC calculates the toe angle using elements of the direction cosine matrix. SVC assumes the y-axis of the wheel center marker is parallel to the spindle axis, and the z-axis is vertical.
Left toe = (180/pi ) arctan( DCL(1,2) / DCL(2,2) )
Right toe = (180/pi ) arctan( -DCR(1,2) / DCR(2,2) )
