Abstract

A data logging unit configured for installation in a hybrid vehicle communicates with a user device configured to receive data from the data logging unit and to display selected portions of the data to a user for identification of potential vehicle faults associated with vehicle events reported by the vehicle'"'"'s driver. The data logging unit has a data logger which communicates with hybrid drive system and other vehicle components to receive hybrid drive system data, and with a vehicle position sensor which detects location to receive vehicle location data. A data log processing module correlates location data with the corresponding vehicle data, and creates a correlated log of drive system data and associated vehicle location information, to allow identification of vehicle data within an event window based on vehicle location at the time of a reported event. Accordingly, a user may make a geographical request and the system will report vehicle data corresponding to the geographical request.

Claims

a first receiver configured to receive hybrid drive data;

a second receiver configured to receive vehicle location data;

a controller configured to correlate the hybrid drive data with the vehicle location data; and

,

a memory configured to record the correlated hybrid drive data and vehicle location data.

2. The system of claim 1, wherein the first receiver is further configured to receive hybrid drive data communicated over a vehicle communication bus.

3. The system of claim 2, wherein the vehicle communication bus is a Controller Area Network (CAN) bus.

4. The system of claim 2, wherein the first receiver is further configured to sample hybrid drive data communicated over the vehicle communication bus.

5. The system of claim 2, further comprising a transmitter configured to transmit the received vehicle location data over the vehicle communication bus;

wherein the first receiver is further configured to receive the vehicle location data transmitted over the vehicle communication bus.

6. The system of claim 1, wherein the second receiver comprises a Global Positioning System (GPS) receiver.

7. The system of claim 1, wherein the vehicle location data is separate from the hybrid drive data, and wherein the first receiver is separate and distinct from the second receiver.

8. The system of claim 1, wherein the controller is further configured to intersperse the vehicle location data in the hybrid drive data.

9. The system of claim 8, wherein the memory is further configured to record the interspersed vehicle location data and hybrid drive data as a combined file.

10. The system of claim 1, wherein the controller is further configured to index the vehicle location data and the hybrid drive data to each other and/or to an independent reference.

11. The system of claim 10, wherein the memory is further configured to record the indexed vehicle location data and hybrid drive data as separate files.
