Remote diagnostic system for vehicles
Diagnosing vehicle anomalies efficiently is dependent upon the expertise of the repair technician, but also the availability of resources. As vehicles have become increasingly computerized, repair technicians have become increasingly specialized in a smaller number of vehicle models. Dealerships and large repair shops have an advantage in that they can more easily afford to obtain specialized electronic tools. However, repair technicians in smaller repair shops often are more skilled, but are unable to afford access to advanced electronic tools and software. A system for using remotely located resources to improve the diagnosis and resolution of vehicle anomalies, including the use of expert technicians and vehicle-specific databases, is disclosed.
1. A method for remotely reprogramming an automobile onboard computer involving
(i) an automobile disposed at a repair shop, the automobile including the automobile onboard computer,
(ii) a first computing device disposed at the repair shop,
(iii) a communication protocol-compliant reprogramming tool that is
(A) connected via a first cable terminating in an OBD-11 connector to the automobile onboard computer, and
(B) connected via a second cable terminating in a USB connector to the first computing device, and
(iv) a second computing device disposed at a location remote from the repair shop, the second computing device including diagnostic software loaded thereon providing functionality to reprogram a vehicle onboard computer via a USB cable connection to a communication protocol-compliant pass-thru device which is itself connected to a vehicle onboard computer;
the method comprising:
(a) receiving, at the second computing device from an automobile diagnostic technician via one or more input devices associated with the second computing device, input corresponding to interaction with a user interface of the diagnostic software, and
(b) remotely reprogramming, by the diagnostic software based on the received input, the automobile onboard computer by communicating data back and forth between the diagnostic software and the vehicle onboard computer, the remote reprogramming comprising:
(I) mimicking, at the second computing device, a USB cable connection to the communication protocol-compliant reprogramming tool by
(A) communicating, by link software loaded on the first computing device to link software loaded on the second computing device, data received at a USB port of the first computing device from the communication protocol-compliant reprograming tool over the second cable,
(B) communicating, by the link software loaded on the second computing device to the diagnostic software, data received from the link software loaded on the first computing device,
(C) communicating, by the link software loaded on the second computing device to the link software loaded on the first computing device, data received from the diagnostic software,
(D) communicating, by the link software loaded on the first computing device to the communication protocol-compliant reprogramming tool via the USB port over the second cable, data received from the link software loaded on the second computing device,
(II) wherein such mimicking allows the diagnostic software to function as if it was directly connected via a USB cable to the communication protocol-compliant reprogramming tool even though it is not.
2. The method of claim 1 , wherein the first computing device is a laptop.
3. The method of claim 1 , wherein the first computing device is enabled to communicate with the second computing device via a subscription.
4. The method of claim 1 , wherein the second computing device accesses the diagnostic software from a vehicle manufacturer.
