Project description

Simulation Engineering X-Vehicle：

The project includes three ECU：Engine、Door and Display.

adopt Control Panel to simulate engine state switching 、 Speed adjustment and door Switch operation , At the same time Display The relevant status is displayed on the panel .

Previous review

Operate in the previous article （CANoe- The first 2 A simulation project -XVehicle—1 Bus database design （ Ideas ）_lamanchas The blog of -CSDN Blog ） in , We define the data in the database , Created XVehicle Each part of the project ECU（ door , engine , Monitor ）、CAN Bus 、 Signals needed for communication 、 message 、 Variable , And the correlation between communication signals and communication nodes . As shown in the figure below ：

Communication nodes ——ECU	​
Communication message —— environment variable	​
Communication message —— message	​
Communication message —— The signal	​
Communication network —— structure	​
Communication network —— Communication nodes	​
Communication network —— Of each communication node Signal receiving and sending	​​​

Why— Panel design

thus ECU Communication definition completed , What this section does is ： Realize simulation Control and Display panel .

Complete the definition of communication network , Next, we need to communicate on the network .

The process of communication involves signal transmission , The received signal shows the state change . So how to make each ECU Signal , And how to make ECU Show your state changes after the signal is sent , Today's main work —— Panel design .

The panel is mainly in the form of visual controls , Simulate components . This is for the operation of components , The status display of components will be more intuitive .

such as , Switch this part （ stay panel It is called a control in ）, stay panel As shown in the figure below , By configuring its properties , It can be completed by clicking the mouse ‘ open ’ Signals and ‘ Turn off ’ The transmission of signals . Drag and drop Speed Control's slider , Change the engine speed .

And such as , Dashboard control , After the engine receives the corresponding signal , It can visually display the current speed .

​​

 What—— Panel design

By the example above , We can find out , Switches and dashboards , One is signaling , One is to show the signal . This is also one of the control classification standards in the panel .

Controls can be divided by control and display 2 Kind of ： Control controls 、 Display controls .

among , Control controls , Used to correlate signals 、 System variables 、 environment variable .

Display controls , For real-time display The signal 、 Variable 、 The value of the diagnostic parameter .

The main controls are ：

How—— Design / To configure Panel Control

Panel Control configuration has two important parts ：

One is , Configure the control's own properties , Such as display style , typeface , Signal format （ Value range , step ）; If it is a control control , that There are also control methods （ For example, what kind of mouse operation does the switch control use , On behalf of 、 Turn off ）; If it is a display control , Then configure the display image （ Such as door status , When receiving the signal of opening the left door , Use picture presentation ）

The other is to select the control to associate Symbol.Panel Controls and these Symbol Connected to a , signify Panel Control is connected to the previously defined communication network ：Panel Control will be from these Symbol Get the information you need , Or to these Symbol Write the information you want to send . The specific implementation of sending and receiving is through ECU Upper CAPL Programming to realize , It will be described in the next section （ Write a link here ）.

among Symbol There are two types of ： One is Signal, One is Variable. After selecting the type to associate , And then Symbol Select the specific variables in this type to associate .

PS：Variable It also includes environment variables 、 System variables . environment variable It is related to the project dbc Created in the , and System variables Is in CANoe Project toolbar Environment Under the System Variables Created in the .（ The functional difference between the two is also a point , Preemptive pit , Write a link and put it here ）

Xvehicle In Engineering Panel Design process

The steps are summarized as follows ：

1. Add system variables ——SystemEnvironment——NameSpace：Engine（EngineStateSwitch,EnginSpeedDspMeter,EngineSpeedEntry）
2. add to Control panel ——Panel Add the control in charge of control （ Door control , Engine control ）
3. add to Display panel ——Panel Add the control responsible for display （ Door display , Engine display ）
4. establish Desktop—— Create a new one DeskTop Tab , hold control Panel window ,Display Panel window ,write window ,Trace Put the windows together , Easy to test and observe . 

  Please move the specific steps （https://blog.csdn.net/lamanchas/article/details/122168798）

Result——Panel Design

After the above steps are completed , The control and display panel is defined , And connected to the communication network .

Then we can use the graphical interface , It is very convenient to change the value of signal or variable , And visually check the output status of the system .
