In-vehicle monitoring and reporting apparatus for vehicles
Systems and methods for monitoring and analyzing vehicle data within a vehicle and providing analytical processing data to prospective users of vehicles are disclosed. In one embodiment, a method is disclosed comprising monitoring a communications bus installed within a vehicle, the communications bus transmitting data recorded by one or more sensors installed within the vehicle; detecting a message broadcast on the communications bus; extracting an event from the message, the extraction based on a pre-defined list of event types; storing the event in a secure storage device installed within the vehicle; determining that a transfer condition has occurred; and transferring the event data to a remote server in response to determining that the transfer condition has occurred.
1. A device comprising:
a write-only storage device;
a volatile memory; and
a processor configured to:
extract an event from a message,
store the event in the write-only storage device,
store the message in the volatile memory,
transfer the event from the write-only storage device to a remote server in response to a transfer condition occurring, and
transfer contents of the volatile memory to the remote server in response to the transfer condition occurring.
2. The device of claim 1 , wherein extracting the event from the message further comprises filtering the message using a set of rules defining a format of accepted messages.
3. The device of claim 2 , wherein the format comprises an identification of a severity level of the message.
4. The device of claim 1 , the processor further configured to encrypt the event before storing the event in the write-only storage device.
5. The device of claim 1 , the processor further configured to pre-process the event by aggregating one or more previous events with the event prior to transferring the event.
6. The device of claim 1 , the processor further configured to:
detect a collision;
transfer the contents of a system memory to the write-only storage device in response to detecting the collision; and
include the contents of the system memory in the event.
7. A method comprising:
extracting an event from a message;
storing the event in a write-only storage device;
storing the message in a volatile memory;
transferring the event from the write-only storage device to a remote server in response to a transfer condition occurring; and
transferring contents of the volatile memory to the remote server in response to the transfer condition occurring.
8. The method of claim 7 , wherein extracting the event from the message further comprises filtering the message using a set of rules defining a format of accepted messages.
9. The method of claim 8 , wherein the format comprises an identification of a severity level of the message.
10. The method of claim 7 , further comprising encrypting the event before storing the event in the write-only storage device.
11. The method of claim 7 , further comprising pre-processing the event by aggregating one or more previous events with the event prior to transferring the event.
12. The method of claim 7 , further comprising:
detecting a collision;
transferring the contents of a system memory to the write-only storage device in response to detecting the collision; and
including the contents of the system memory in the event.
13. The method of claim 7 , further comprising:
monitoring a communications bus, the communications bus connecting one or more sensors and transmitting data recorded by the one or more sensors; and
detecting the message broadcast on the communications bus.
14. Anon-transitory computer-readable storage medium for tangibly storing computer program instructions capable of being executed by a computer processor, the computer program instructions defining steps of:
extracting an event from a message;
storing the event in a write-only storage device;
storing the message in a volatile memory;
transferring the event from the write-only storage device to a remote server in response to a transfer condition occurring; and
transferring contents of the volatile memory to the remote server in response to the transfer condition occurring.
15. The non-transitory computer-readable storage medium of claim 14 , wherein extracting the event from the message further comprises filtering the message using a set of rules defining a format of accepted messages.
16. The non-transitory computer-readable storage medium of claim 15 , wherein the format comprises an identification of a severity level of the message.
17. The non-transitory computer-readable storage medium of claim 15 , the steps further comprising encrypting the event before storing the event in the write-only storage device.
18. The non-transitory computer-readable storage medium of claim 15 , the steps further comprising pre-processing the event by aggregating one or more previous events with the event prior to transferring the event.
19. The non-transitory computer-readable storage medium of claim 15 , the steps further comprising:
detecting a collision;
transferring the contents of a system memory to the write-only storage device in response to detecting the collision; and
including the contents of the system memory in the event.
20. The non-transitory computer-readable storage medium of claim 15 , the steps further comprising:
monitoring a communications bus, the communications bus connecting one or more sensors and transmitting data recorded by the one or more sensors; and
detecting the message broadcast on the communications bus.
