1. INTRODUCTION This manual describes the basic concepts and methods for using AVL CRUISE to simulate engine/powertrain systems.
1.1. Scope This manual describes how to use CRUISE. It does not attempt to discuss all concepts of CRUISE are required to obtain successful solutions. It is theofuser’s responsibility to determinethat if he/she has sufficient knowledge and understanding vehicle simulation to apply this software appropriately.
1.2. User Q uali fi cati on It is recommended that the user has a basic understanding of the GUI before beginning this example. This document is a basic qualification for operating CRUISE and users are recommended to continue with CRUISE training courses.
1.3. Symbo ls The following symbols are used throughout this manual. Safety warnings must be strictly observed during operation and service of the system or its components.
Caution: Cautions describe conditions, practices or procedures which could result in damage to, or destruction of data if not strictly observed or remedied.
Note: Notes provide important supplementary information.
Convention Italics
Meaning For emphasis, to introduce a new term or for manual titles.
monospace
To indicate a command, a program or a file name, messages, or input / output on a screen or file contents.
SCREEN-KEYS
A SCREEN font is used for the names of windows and keyboard keys, e.g. to indicate that you should type a command and press theENTER key.
MenuOpt
A MenuOpt font is used for the names of menu options, submenus and screen buttons.

2. OVERVIEW 2.1. Wor kf lo w The following steps are recommended for the workflow: 1.
Create project/version
2.
Create vehicle model
3. 4.
Input the data in components Create connections: Energetic
5.
Create connections: Informational
6.
Create task folders and add tasks
7.
Set up calculation
8.
Run calculation
9.
View and evaluate results
The user is guided through these steps in the example description in the following chapter.
2.2. Com po nents The components used to build systems are located under the Desk Area – Modules Sidebar. Click on a component group and select a component by clicking it with the left mouse button. Keep the left mouse button pressed and drag it into the vehicle model area.

2.3. Connections The two types of connections are described as follows:
s n o it c e n n o C c ti e rg e n E
l a n o ti a rm o f n I
n o ti c e n n o C
Mechanical Connection
Exhaust Connection
Electrical Connection
Informational Connection
Energetic:
Connections which transfer energy are divided by the type of energy which is transferred into the following groups: •
Mechanical
•
Exhaust System
•
Electrical
The energetic connections are established by poly-lines between the pins. Informational: Information to the Da ta Bus is the only informational connection.
The energetic connections are represented in the form of lines on the screen. The components with informational connections have only a small colored arrow on the left bottom corner of the symbol. To connect the different modules with information-flow, open the Data Bus dialog by double clicking with the left mouse button on the colored lines (red, green, and blue) at the bottom of the Vehicle Modeler. The following window opens:
Figure 2-1: Data Bus Window
2-2
20-Sept-2013
Primer
CRUISE v2013
The connections in the Data Bus are described as follows: In the first column (Component ... requires ) all components are listed which can receive information from other components (e.g. Engine ). In the second column (Input Information ... from ) all signals that the component, selected in the first column, can accept will be displayed (e.g. Load Signal ). Signals that are marked in blue in this column have to be connected; signals marked in black are optional. After selecting a signal in the second column, in the third column (Component ... delivering ) all components appear which can deliver such information (e.g. Cockpit ; in this case the only component that can deliver a Load Signal). In the fourth column ( Output Information ...) the signals appear that the component, selected in the third column, can deliver and that match the information, selected in the second column (e.g. Load Signal ). In CRUISE a pre-selection is done so that only the components that can provide the input information as requested in the second column are presented in the third and fourth columns (in this case only the Cockpit can deliver an information like the Load Signal ). For this example the Cockpit delivers the information about the actual Load Signal to the engine, where it is used to determine the output torque. In the graphical form this is displayed as follows:

3. MANUAL FRONT WHEEL DRIVE EXAMPLE This chapter describes how to create and run the model of a manual front wheel drive. The Pr i mer . pr j file is used in this example. It is recommended to refer to the CRUISE Users Guidefor more detailed information. 1. Start CRUISE by double clicking on the icon on the desktop or from Start selecting Menu/All Programs/AVL/Cruise 2. When CRUISE is started, the Layout and Platform Selection
window opens.

Note: Some components do not need links and can stand alone (i.e. monitor, vehicle, cockpit). Components such as clutch, brake, wheel may not be connected correctly.
1. To connect the components, observe the following:
20-Sept-2013

CRUISE
Primer
a.
Move connecting pin to desired position. Do the same with the other component’s connecting pin.
b. To connect, right-click on the connecting pin. Then, from the context menu, select Connect . c.
Drag the line to the other connecting pin and click with the left mouse button.
Note: Only the same type of connecting pins can be connected.
d. Connection line is now complete. 2. Complete the connection lines on the rest of the components as shown in Figure 3-3.
Note: Some components have more than one pin (e.g. gearbox). Here
one pin is usually the input, the other one is the output. When connecting the components make sure that the connections are made correct (input should always be the engine side), otherwise the transmission can work in the wrong direction!
Most of the components have all the required connectors. In Differential (D) – Brake (B) – Wheel (W), Brake has only one mechanical connector. The mechanical diagram is as follows:
For a better representation pins can also be cloned. By cloning the existing pin on the Brake component, the user can create two connections: one to connect the Brake to the Wheel component and one to connect to the Transmission. By cloning the pin, all input data and output data for both pins is cloned. Thus, CRUISE considers both pins as one connection. Select the connecting pin as if you were choosing Connect , but choose Clone Pin from the context menu. This creates another connection on Brake, which should be moved to the appropriate spot.

3.5. Conn ection s: Info rmatio nal 1. When all connections are complete, open the Data Bus by double clicking on the colored lines (red, green and blue) at the bottom of the screen. The Data Bus makes the necessary connections and options for informational connections in the system. In the Data Bus window, the four columns contain items that must be linked together correctly. All items marked in blue must be connected. Items marked in black are optional and are connected at the user’s discretion. In the first column, click on Engine and Load Signal appears in the second column. Click on Load Signal and Cockpit appears in the third column. Click on Cockpit and Load Signal appears in the fourth column. If all is correct, click on Load Signal in the fourth column. The aforementioned objects in Columns B, C and D will now have the red, green, and blue lines before them. If all necessary connections for a component are made, this component name will be marked bold and gets a green tick in front of the name. 2. Connect the components as described in the following table. Component Requirement
