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.
The x-axis points to the forward direction or the longitudinal direction, the y-axis, which represents the lateral direction, is positive when it points to the right of the driver, and the z-axis points to the ground

13 Σεπ 2021 · The coordinate system is orientation in terms of x, y and z relative to the vehicle, as in which axis goes in which direction; normally defined as {x, y, z} in terms of the directions of the vehicle. For example ISO uses {Forwards, Leftwards, Upwards} as shown above, whereas SAE uses {Forwards, Rightwards, Downwards} and there are lots more ...
The earth-fixed axis system is a right-hand orthogonal axis system with the coor-dinates XE, YE, and ZE. The XE and YE coordinates are usually fixed on the road plane, e.g. at the beginning of a driving maneuver. It allows describing the vehicle movement relative to a point on the road. Vehicle axis system.
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.
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.
