Abstract

Systems and methods for driver evaluation, rating, and skills improvement are disclosed. A particular embodiment is configured to: receive vehicle data from vehicle subsystems of a vehicle via a vehicle subsystem interface; correlate the vehicle data to a corresponding set of preprocessing events representing activity or state transitions occurring in the vehicle; aggregate the set of preprocessing events into a plurality of data blocks, wherein each data block corresponds to a user-configurable time frame; and transfer the plurality of data blocks to a central server via a network interface and a network.

Claims

1. An in-vehicle telematics unit comprising:

one or more data processors;

a vehicle subsystem interface to connect the telematics unit with one or more vehicle subsystems of a vehicle;

a network interface to connect the telematics unit with a central server via a network; and

telematics unit processing logic, executable by the one or more data processors, to;

receive vehicle data from the vehicle subsystems via the vehicle subsystem interface;

correlate the vehicle data to a corresponding set of preprocessing events representing activity or state transitions occurring in the vehicle;

aggregate the set of preprocessing events into a plurality of data blocks, wherein each data block corresponds to a user-configurable time frame; and

transfer the plurality of data blocks to the central server via the network interface.

2. The in-vehicle telematics unit of claim 1 wherein the network is of a type from the group consisting of:

the Internet, a cellular network, a satellite-based network, and a wireless network.

3. The in-vehicle telematics unit of claim 1 further including a mobile device interface to connect the telematics unit with one or more mobile devices.

4. The in-vehicle telematics unit of claim 1 wherein each of the data blocks includes driver identification credentials.

5. The in-vehicle telematics unit of claim 1 wherein at least one of the preprocessing events in the set of preprocessing events is of a type from the group consisting of:

a defensive driving event, efficient engine management event, cruise control usage event, retarder usage event, idling time event, heavy braking event, handbrake usage event, steady driving event, excessive speed event, and an accelerator position event.

6. The in-vehicle telematics unit of claim 1 wherein each of the data blocks are generated in real time.

7. The in-vehicle telematics unit of claim 1 being further configured to generate condensed driver evaluation information in relation to a configurable time frame based on the set of preprocessing events.

8. A central server comprising:

one or more data processors;

a network interface to connect the central server with a telematics unit in a vehicle and at least one client device via a network; and

server processing logic, executable by the one or more data processors, to;

receive a plurality of data blocks from the telematics unit, each data block including a set of preprocessing events representing activity or state transitions occurring in the vehicle, wherein each data block corresponds to a user-configurable time frame;

generate a Degree of Trip Difficulty (DTD) value and a Raw Driver Score (RDS) value from the plurality of data blocks;

generate a normalized Driver Evaluation Rating (DER) from the DTD value and the RDS value; and

transfer the DER to a user interface of the at least one client device.

9. The central server of claim 8 wherein the network is of a type from the group consisting of:

the Internet, a cellular network, a satellite-based network, and a wireless network.
