I am working on a system to assess the driving style of drivers.
I need get the vehicle speed data out from vehicle. Earlier it was possible through CAN interface exposed through OBDII interface but now many car manufacturers are closing that interface.
So I need to know if there is any other mechanism to get speed.
I need some who understands the vehicle CAN network and its interfaces.
Pls note that we are NOT going to use GPS to get the speed.
Let me know if you have any possible solution for the problem statement.
