Original Abstract Submitted

A unified electronic control unit (ECU) interface provides a bridge from ECU clients to the ECU. The ECU interface may be implemented on a vehicle's onboard computer, and it may be used by clients executing on the onboard computer and, in some cases, by clients outside the onboard computer. The ECU interface may receive a request from a client in a first messaging format, e.g., a local networking protocol used by processes running on the vehicle. The ECU interface translates the request into a second messaging format and transmits the request to the ECU. The ECU interface receives a response from the ECU and translates the response into the first messaging format for delivery to the client. The ECU interface may further perform authentication of the client and/or the ECU, packet serialization of the response from the ECU, packet diagnostics, and other functionalities associated with communicating with the ECU.
