Systems and methods for accessing vehicle communications bus information for an application processor
First Claim
1. A vehicle interface system for accessing data in real time from an onboard diagnostics system through a vehicle interface and a vehicle communications bus and transmitting the data to an application processor running an application primary process, comprising:
- a vehicle interface processor;
a processor data interconnect system capable of transferring data between the vehicle interface processor and the application processor;
a vehicle communications bus electrical connection system operatively connected to the vehicle interface and capable of transferring diagnostic data between the vehicle interface processor and the onboard diagnostics system;
vehicle interface software running on the vehicle interface processor; and
an application data collection process running on the application processor using spare cycles not used by the application primary process;
whereinthe application data collection process communicates with the vehicle interface software using the processor data interconnect system to cause the vehicle interface processorto collect data from the onboard diagnostics system in real time using the vehicle communications bus electrical connection system,to store the data collected from the onboard diagnostics system; and
to transfer the data collected from the onboard diagnostics system to the application processor using the processor data interconnect system as requested by the application data collection process.
