Description

Note

Simulating models with the Simulation 3D Motorcycle block requires Simulink^® 3D Animation™.

The Simulation 3D Motorcycle block implements a motorcycle with two wheels in the 3D simulation environment.

To use this block, ensure that the Simulation 3D Scene Configuration block is in your model. If you set the Sample time parameter of this block to -1, the block uses the sample time specified in the Simulation 3D Scene Configuration block.

The block input uses the vehicle Z-down right-handed (RH) Cartesian coordinate system defined in SAE J670¹. The coordinate system is inertial and initially aligned with the vehicle geometric center:

X-axis — Along vehicle longitudinal axis, points forward
Y-axis — Along vehicle lateral axis, points to the right
Z-axis — Points downward

Tip

Verify that the Simulation 3D Motorcycle block executes before the Simulation 3D Scene Configuration block. That way, Simulation 3D Motorcycle prepares the signal data before the Unreal Engine^® 3D visualization environment receives it. To check the block execution order, right-click each block and select Properties. On the General tab, confirm these Priority settings:

Simulation 3D Scene Configuration — 0
Simulation 3D Motorcycle — -1

For more information about execution order, see Control and Display Execution Order.

Translation — Motorcycle translation
`4`-by-`3` array

Motorcycle and component translation, in m. Array dimensions are 4-by-3.

Translation(1,1), Translation(1,2), and Translation(1,3) — Motorcycle translation along the inertial vehicle Z-down X-, Y-, and Z- axes, respectively.
Translation(...,1), Translation(...,2), and Translation(...,3) — Motorcycle component translation relative to vehicle, along the vehicle Z-down X-, Y-, and Z- axes, respectively.

The signal contains translation information according to the locations.

$T r a n s l a t i o n = [\begin{matrix} X_{v} & Y_{v} & Z_{v} \\ X_{H} & Y_{H} & Z_{H} \\ X_{F} & Y_{F} & Z_{F} \\ X_{R} & Y_{R} & Z_{R} \end{matrix}]$

Light controls — Vehicle lights on or off
1-by-5 vector

Light controls input signal, specified as a 1-by-5 Boolean vector. Each element of the vector turns a specific vehicle light on or off, as indicated in this table. A value of 1 turns the light on; a value of 0 turns the light off.

Vector Element	Vehicle Light
(1,1)	Headlight high beam
(1,2)	Headlight low beam
(1,3)	Brake
(1,4)	Left signal
(1,5)	Right signal

Dependencies

To create this port, on the Light Controls tab, select Enable light controls.

Vehicle Parameters

Type — Type
`Sports bike` (default) | `Motor bike` | `Scooter`

Use the Type parameter to specify the motorcycle type. This table provides links to the motorcycle dimensions.

Vehicle Type Setting	Vehicle Dimensions

`Motor bike`	Motor Bike
`Scooter`	Scooter

Color — Color of vehicle
`Red` (default) | `Orange` | `Yellow` | `Green` | `Blue` | `Black` | `White` | `Silver` | `Dazzle Camouflage`
