Sedan vehicle dimensions


Sedan is one of the vehicles that you can use within the 3D simulation environment. This environment is rendered using the Unreal Engine® from Epic Games®. The diagram provides the dimensions of this vehicle. The height dimensions are with respect to the vertical ground plane. The length and width dimensions are with respect to the origin of the vehicle in the vehicle coordinate system. The origin is on the ground, at the geometric center of the vehicle. For more detailed views of these diagrams, see the Dimensions section.

To add this type of vehicle to the 3D simulation environment:

  1. Add a Simulation 3D Vehicle with Ground Following block to your Simulink® model.

  2. In the block, set the Type parameter to Sedan.

Top-down view of sedan with the origin marked in blue at its center and its width dimensions shown. The width not including rear-view mirrors is 1.842 meters. The width including rear-view mirrors is 2.107 meters.

Side view of sedan with the origin marked in blue beneath its center and its length and overhang dimensions shown. The rear overhang is 1.119 meters. The distance from the rear overhang to the origin is 1.305 meters. The distance from the origin to the front overhang is 1.513 meters. The front overhang is 0.911 meters. The tire radius is 0.350 meters.

Front view of sedan with the origin marked in blue beneath its center and its front tire width and front axle dimensions shown. The front tire width is 0.213 meters. The front axle width is 1.573 meters.

Rear view of sedan with the origin marked in blue beneath its center and its rear tire width, rear axle dimensions, and height shown. The rear tire width is 0.213 meters. The rear axle width is 1.572 meters. The height from the ground to the tire center is 0.271 meters. The height from the tire center to the top of the vehicle is 1.246 meters.

Sensor Mounting Locations

In the 3D simulation sensor blocks, use the Mounting location parameter to mount sensors at predefined locations on the vehicle. The table shows the X, Y, and Z positions of the mounting locations relative to the vehicle origin. These locations are in the vehicle coordinate system, where:

  • The X-axis points forward from the vehicle.

  • The Y-axis points to the left of the vehicle, as viewed when facing forward.

  • The Z-axis points up from the ground.

Specify Sedan Vehicle Dimensions

When simulating a path planner in the 3D environment, the path planner must use a vehicle whose dimensions are consistent with one used in the 3D environment. To make these dimensions consistent, you can use a vehicleDimensions object.

Specify the dimensions of a Sedan vehicle in a vehicleDimensions object. Units are in meters. For an example that uses this object in a path planner, see Visualize Automated Parking Valet Using Unreal Engine Simulation.

centerToFront = 1.513;
centerToRear  = 1.305;

rearOverhang  = 1.119;

vehicleHeight = 1.517;
vehicleLength = centerToFront + centerToRear + frontOverhang + rearOverhang;
