Benefits of technology
This approach provides a rich data set for more accurate vehicle problem diagnosis, enabling rapid identification of issues and preventing potential damage by allowing for real-time analysis and notification, while also accommodating user-defined conditions and reducing data transmission costs.
Problems solved by technology
The sheer quantity of operational data being generated by the various vehicle components and subsystems makes storing or archiving all of such operational data problematical.
Some vendors do provide data logging systems for temporary use in vehicles, where all the operational data generated by the vehicle is stored for later analysis, but such data logging systems are not designed for long term use.
Even with the data provided by fault codes, accurate diagnosis of complex or unusual vehicular system failures can be problematical.

Embodiment Construction
[0033]Figures and Disclosed Embodiments are not Limiting
[0034]Exemplary embodiments are illustrated in referenced Figures of the drawings. It is intended that the embodiments and Figures disclosed herein are to be considered illustrative rather than restrictive. No limitation on the scope of the technology and of the claims that follow is to be imputed to the examples shown in the drawings and discussed herein. Further, it should be understood that any feature of one embodiment disclosed herein can be combined with one or more features of any other embodiment that is disclosed, unless otherwise indicated.
[0035]As used herein and in the claims that follow, a reference to an activity that occurs in real-time is intended to refer not only to an activity that occurs with no delay, but also to an activity that occurs with a relatively short delay (i.e., a delay or lag period of seconds or minutes, but with less than an hour of lag time).

Operational data generated and used in a vehicle to control various vehicular systems is temporarily stored in a data buffer in the vehicle. A processor in the vehicle is configured to detect anomalous conditions, which can be based on predefined fault codes or user defined conditions (based on a single parameter or a combination of parameters). Whenever such an anomaly is detected, a diagnostic log is conveyed from the vehicle to a remote location. Such a log will include the detected anomaly, and buffered operational data. In at least one embodiment, the diagnostic log includes buffered operational data collected both before and after the anomaly. The diagnostic log is analyzed at the remote location to diagnose the cause of the anomalous condition, so a decision can be made as to whether the vehicle requires immediate repair, or whether the repair can be scheduled at a later time.
