Read and Process OBDII signals in real-time

Is it possible to use an Arduino board to read the CAN signals through OBDII port in real-time and process the CAN signals and display the results to the drivers display.

If yes, to process the CAN signals I have developed the strategy in Simulink. Also I saw that it is possible to directly connect the simulink and arduino board using the in-built applications, but how can i give the inputs coming from the vehicle directly to my model to process it.

Please help me find a solution.
