Vehicle Dynamics Blockset™ uses these coordinate systems to calculate the vehicle dynamics and position objects in the 3D visualization environment. The right-hand rule establishes the X - Y - Z sequence and rotation of the coordinate axes used to calculate the vehicle dynamics.
In most studies related to handling and directional control, only the X-Y plane of the vehicle is considered. The vertical axis, Z, is often used in the study of ride, pitch, and roll stability type problems. The following list defines relevant definitions for the variables associated with this research.

13 Σεπ 2021 · In the VeSyMA vehicle templates, there is the vehicleXYZ block in the top left hand corner of the diagram layer that defines the coordinate system. As shown below, this allows users to define the orientation of the vehicle. Figure 2: vehicleXYZ in a vehicle model. Using origins and coordinate systems
A world coordinate system is important in global path planning, localization, mapping, and driving scenario simulation. Automated Driving Toolbox uses the right-handed Cartesian world coordinate system defined in ISO 8855, where the Z-axis points up from the ground. Units are in meters.
24 Σεπ 2021 · The earth-fixed axis system is a right-hand orthogonal axis system with the coordinates \ (X_\mathrm {E}\), \ (Y_\mathrm {E}\), and \ (Z_\mathrm {E}\). The \ (X_\mathrm {E}\) and \ (Y_\mathrm {E}\) coordinates are usually fixed on the road plane, e.g. at the beginning of a driving maneuver.
• We can define the wheel frame as the orthogonal frame formed by the contact plane normal, the wheel hub projected onto the plane, and the axle vector projected onto the plane • The tire produces forces along these axes known as the normal force , longitudinal force 𝑔, and lateral force
