Calculate and Convert Heart Rate: Speed Pulse

Hallo an alle!

I'm looking for a way to read the speed information from the CAN bus and convert it into an accurate value. My idea is as follows:
Die Speed Information ist auf der OBDII Schnittstelle eine genormte Information.
Ich möchte daher eine Software schreiben, die 2 Lawicel CANUSB Interfaces gleichzeitig anspricht (auf der einen Seite OBD auf der anderen Inneraum CAN; oder auch 1x AGV4000 und 1x Lawicel CANUSB).
The software currently knows the vehicle's current speed (from the OBD interface).

The software should now:
a) Filter IDs from the interior CAN bus that are speed-dependent and suggest them.
b) For the selected ID, identify the relevant bit range.
c) Perform a conversion to convert the read values into km/h and display this conversion factor.
d) After the conversion and storage of the data without OBD, correctly display the current speed based on the information from the interior CAN bus.

Do you have any ideas on how this can be implemented?
