In the window toolbar Select y-axis view Icon ·, Select Show All Y-Axis, So the three added above Signal Will be displayed in the same window , As shown in the figure .

7.2 State Tracker window

stay CANoe Select from the menu bar Analysis→State Tracker→New State Tracker Window, Enter a name of Signal State.

Right click in the signal list bar on the left of the window and select Add Variables, Add system variables Vehicle Control Medium Gear and Brake.

Right click in the signal list bar on the left of the window and select Add Database Objects→Signals, Add signal VehicleLight, As shown in the figure .

When the measurement starts ,Gear、Brake and VehicleLight Of Value Table It can also be displayed in the right column .

 7.3 Data window

Can be in Data Add signals and system variables to the window , Here we add Driver、EngSpeed and KeyState Three signals , as well as Left_Turn_Enable and Right_Turn_Enable Two system variables , As shown in the figure .

 8 Trace Windows and Logging

Trace The window helps users view and analyze data on the bus in real time .

Logging The data in the whole simulation process is recorded , In the case of large amount of data or long-term testing , This enables the user to view the activity of the bus in the offline state , meanwhile ,Logging The data recorded by the function can be found in CANoe Play back in , It plays a very important role in the recurrence of problems on the bus .

8.1 Trace window

Trace window ： Create a CAN_Trace Of Trace window

 8.2 Logging window

Logging window ： Create a CAN_Logging Of Logging modular , stay measurement setup Panel add CAN Channel filter .

stay 12.4.5 In the festival , This book is at the node Gateway Of CAPL Keyboard events are added to the program to control CAN_Logging The function of opening and closing modules , On the keyboard 1 Key can realize Logging Start and stop of functions , You can check the relevant code （5.3 Summary ）.

Right click CAN_Logging Module selection Configuration, stay TriggerConfiguration Select in window Toggle Trigger Pattern , take Toggle on and Toggle off The mode selection of is CAPL and User defined, The setting result is shown in the figure .

After setting up , Readers can Measurement Setup Set in advance in the window CAN_Logging switch , You can also use the... On the keyboard during the measurement process 1 Key to control Logging The beginning and the end of .

 10 Project operation test

Because the instance adopts a simplified topology , The node does not exceed 4 individual , So in Demo edition CANoe The simulation can also run normally . Address of engineering documents （ Upload git Post update ）

10.1 Automation Sequences Drive trigger ,Bug analysis （ System variable with the same name , The signal ）

After completing all the above configurations , Readers can be in CANoe Run the simulation project in the software .

The functions realized by simulation engineering follow Automation Sequences Drive and trigger , Can be observed Control Panels and IPC Synchronized changes in the panel .

The running effect of the simulation project is shown in the figure .

As you can see in the picture above ,IPC It can display the car speed normally , Oil quantity , Oil temperature , Engine speed , cornering lamp .

But the gear display is incorrect . alike Control The gear text display on the panel is also incorrect .

So next, look at the analysis panel , As shown in the figure below ：

You can find KeyState Signal diagram changes with Automation Sequences Changes are synchronous , But in IPC and Control The panel does not display correctly .

We see the IPC The display of the panel is as follows , It is found that the gear display is bound to Signal Gear：

  therefore , The next in analysis Add Signal Gear The observation of , For intuitive observation , Separately signal observe Interface and Data Interface add Gear The signal . Here's the picture ： The discovery is consistent with the display , Has always been a Parking No change. .

Have a close look at CAPL Code , Make sure there's no problem .

Suddenly thought of , Set before Sequences when ,keyState There is an error in the value of , So will it Automation Sequences In this Gear There is something wrong with the setting ？

First ,Gear Whether the value is wrong ： see Sequences Medium Gear, The value is in the optional range , There is no mistake .

  here , see Gear This Object, It is found that the same name is Gear There are two objects of , One is signal, One is system variable,

Here we choose signal Of Gear, But here we use sequences to simulate vehicle control , What should be controlled is the system variable Gear. The problem should be here .

Next , modify Gear For the system variable Gear, Modify the corresponding value R、N、D.

Run the sequence again , The panel displays as follows , Results the correct .

 10.2 Manual operation Control panel

It can also be operated manually Control panel , At the same time combined with Trace、Graphic and State Tracker Wait for the analysis window , Do some testing and analysis . Press 1 key Logging File start recording CAN Trace Information in , Press again 1 key , Will stop Logging Record .

Press CAPL Program logic test , All display normal operation .

• The control of engine speed , Didn't understand
• There is no corresponding sensor data for oil temperature and oil volume , Only initial values are displayed

10.3 analysis Write Information ,warning Repair （ Message sending type , Signal transmission type ）

Got write The window output information is as follows ：

  There are two Warning.

1. among Driver The signal is set to the default value and sent circularly , But the cycle time is not set .
2. message Driver_Info Not set Send type .

The following is an analysis , modify ：

stay CANoedb++ Look at the signal Driver Properties of , The signal Driver Subordinate message Message::Diver_Info

at present , Their two send type properties The settings are as follows ：（ The settings given in the book ）.

Message::Diver_Info	GenMsgSendType	NoMsgSendType
Signal::Driver	GenSigSendType	NoSigSendType

（ The attribute information description of the database can be referred to ：CANoe - Description of common database attributes _lamanchas The blog of -CSDN Blog ）

Message sending type There are several values of ：

  Message sending type The detailed meaning of attributes is shown in the following figure ：

  Simply speaking , Message sending type The whole is divided into ： Events trigger and Cycle triggers .

According to the previous functions , We know Driver Information about , By BCM The control of the , open BCM Of CAPL. In the program , message The update and sending of are triggered by events , And always monitor Car_Driver The signal , Not jump trigger .

  So it should be in DBC Set the message sending type as ifactive

 Driver The signal is also set to ifactive

  preservation DBC after , Rerun ,write Warning prompt ：

 System：In message 'Driver_Info' the signals using send types 'WithRepetition' or 'IfActive' were downgraded, because CycleTimeFast is 0.

The message alarm disappears , But the signal cannot be set to ifactive, because ifactive It also involves the setting of the cycle .

The next in DBC in modify Driver The transmission of signals The type is onchange

  thus , All alarms disappear .
