1 Vehicle coordinate system for the dynamics
X for the forward positive values at the position of the front axleCITATION Mar17 \p 5 \l 1033 (Lanfrit, 2017, p. 5).
Z for the vertical positive values where the origin is the ground level.
Y is for the right side positive values and is centered on the plane of symmetry.
For the general design of the vehicle;
X is for the forward positive values at the position of the front axle.
Z for the vertical positive values where the origin is at any convenient point of the vehicle. For the design, the convenient position is the center of gravity.
Y describes the positive values of the left of the vehicle and is centered on the plane of symmetry. Table 1 shows the coordinates of the car cross-section.
