CanBUS addresses from FSM

[leomonde]

@Tigo2000 sorry if I write here, but I am looking for CAN data information about FSM of a 2015 Volvo.
I am running an openpilot software to control my Volvo, but it's very hard to understand all messages from FSM.
Some I already figure out, most I don't, so I am looking for info about hex address, lenght, offset, of FSM messages.
Maybe you already have a kind of table (like this https://github.com/Tigo2000/Volvo-VIDA/raw/main/images/Get-CANValuesUsingEcuId.png?raw=true).
I also have VIDA installed, but I am not sure how to use your tool, I don't know anything about SQL.
Thanks.

Hi Leo,

To run the SQL queries you can install a tool like SQL Server Management Studio (SSMS), however the PowerShell scripts might be easier to use.

Assuming you have VIDA installed you can run the PowerShell script Get-CarProfiles.ps1 to fetch the identifier of a given car, for example a V60 2015 (which is 0b00c8af86223698). The script will prompt for SQL database credentials, these can be found in the README at the top.

Once you have the identifier, you can open and edit the Get-ParametersForAllECUs.ps1 script, change the row with the $selectedProfile to the V60 identifier (or car title) and then run the script to actually fetch the CAN commands from the VIDA database.

$selectedProfile = $profiles | Where-Object title -eq 'V60 2015 '

or

$selectedProfile = $profiles | Where-Object identifier -eq '0b00c8af86223698'

Afterwards, it will have created a CSV for all the ECUs. I have added the CSV for the FSM of a V60 2015 below.

If you run into anything, let me know!

Thank you.
I tried to launch script with power shell but after db login I got some red errors. (yes, I have Vida installed and working)
I believe something is missing in my Win 7.
(do I need to launch script while car is connected over OBD2?)

The data I am looking for is the data FSM uses over CAN to steer and change car speed.
Here what I found until now (in dbc format):

BO_ 81 FSM0: 8 0x51
SG_ ACC_FrontCar : 16|1@0+ (1,0) [0|1] "" XXX
SG_ ACC_Available : 17|1@0+ (1,0) [0|7] "" XXX
SG_ ACC_Enabled : 18|1@0+ (1,0) [0|1] "" XXX
SG_ ACC_BrakeAlert : 27|1@0+ (1,0) [0|1] "" XXX

BO_ 608 FSM1: 8 0x260
SG_ ACC_Distance : 7|8@0+ (1,0) [0|255] "" XXX

BO_ 610 FSM2: 8 0x262
SG_ TrqLim : 23|8@0+ (1,-128) [0|255] "" PSCM
SG_ LKAAngleReq : 29|14@0+ (0.04,-327.68) [0|16383] "" PSCM
SG_ LKASteerDirection : 41|2@0+ (1,0) [0|3] "" PSCM
SG_ Checksum : 55|8@0+ (1,0) [0|255] "" PSCM

BO_ 624 FSM3: 8 0x270
SG_ ACC_Standstill : 0|1@0+ (1,0) [0|1] "" XXX
SG_ ACC_Check : 2|1@0+ (1,0) [0|1] "" XXX
SG_ ACC_AccelerationRequest : 15|8@0+ (0.04,-5.04) [0|255] "" XXX

BO_ 794 FSM4: 8 0x31A
SG_ ACC_LeadSpeed : 31|8@0+ (1,0) [0|255] "" XXX

BO_ 1021 FSM5: 8 0x3FD
SG_ TSR_Speed : 25|4@1+ (10,0) [0|15] "km/h" XXX

The main data are LKAAngleReq used to steer and ACC_AccelerationRequest used for gas and brake.
The ACC_FrontCar is 1 when radar detect a car ahead, ACC_Distance and ACC_LeadSpeed are distance and speed of ahead car.
The TSR_Speed is the road speed limit read by FSM on a sign.
