Abstract

A novel fuel savings scoring system is capable of analyzing real-time on-board diagnostics (OBD) information of a vehicle from a remote monitoring station unit. The fuel savings scoring system can derive a novel fuel efficiency comparison metric called “driving score.” Preferably, the driving score represents a commercial vehicle driver'"'"'s fuel efficiency driving performance relative to those of peer commercial drivers in a commercial vehicle fleet organization. The driving score takes account of a current real-time mileage achieved by a particular vehicle as well as the best empirical mileage achieved by the same make and model to the particular vehicle in the commercial vehicle fleet organization. Furthermore, in some embodiments of the invention, the driving score for the particular vehicle can even be route and traffic condition-sensitive, which further improves the realistic usefulness of the driving score as a comparative fuel efficiency driving performance measure among commercial vehicle drivers.

Claims

1. A fuel savings scoring system with a remote real-time vehicle on-board diagnostics monitoring, the fuel savings scoring system comprising:

a vehicle on-board diagnostics unit connected to an engine control unit or a vehicular control chipset of a vehicle to record, diagnose, and generate engine, vehicle dynamics, and fuel consumption data as a real-time data stream;

a commercial vehicle fuel consumption analytics module that receives the real-time data stream from the vehicle on-board diagnostics unit, while also receiving best empirical mileage data achieved by the vehicle itself or a peer vehicle of same model and make from a commercial fleet fuel consumption database associated with a commercial vehicle fleet company;

a fuel savings score analytics unit in the commercial vehicle fuel consumption analytics module, wherein the fuel savings score analytics unit calculates a driving score by dividing a current fuel mileage of the vehicle by a best empirical mileage number achieved by the vehicle itself or by the peer vehicle of same model and make, and then multiplying by 100;

the commercial fleet fuel consumption database that accumulates, stores, and categorizes fuel consumption records downloaded from the vehicle and a plurality of peer vehicles of same model and make; and

a computer server or another electronic device with a CPU and a memory unit that executes the fuel savings score analytics unit and the commercial fleet fuel consumption database to calculate and display the driving score on a display panel in the vehicle or in a remote monitoring station unit.

2. The fuel savings scoring system of claim 1, further comprising an on-board diagnostics data transceiver unit in the vehicle and a data communication network to transmit the real-time data stream from the vehicle on-board diagnostics unit to the computer server or to the remote monitoring station unit wirelessly.

3. The fuel savings scoring system of claim 2, wherein the on-board diagnostics data transceiver unit in the vehicle is capable of requesting and receiving the best empirical mileage data from the commercial fleet fuel consumption database executed by the computer server or another electronic device.

4. The fuel savings scoring system of claim 1, wherein the fuel savings score analytics unit in the commercial vehicle fuel consumption analytics module further comprises an onboard diagnostics information management module, a vehicle location and route information management module, an empirical best mileage management module for the peer vehicle of same model and make to the vehicle, a driving score calculation module, and an information display management module.

5. The fuel savings scoring system of claim 1, wherein the commercial vehicle fuel consumption analytics module is a vehicle-side module, a computer server-side module, or both.

6. The fuel savings scoring system of claim 1, further comprising a vehicle location and route information management module that correlates the best empirical mileage data achieved by the vehicle itself or the peer vehicle of same model and make to vehicle routes and traffic conditions when each data point was recorded for the vehicle and the peer vehicle.

7. The fuel savings scoring system of claim 6, wherein the best empirical mileage number achieved by the vehicle itself or by the peer vehicle of same model and make, for calculation of the driving score of the vehicle, is adjusted for the vehicle routes and traffic conditions when each data point was recorded for the peer vehicle.

8. The fuel savings scoring system of claim 1, further comprising an information display management module for generating graphical data to display the driving score on the display panel in the vehicle or in the remote monitoring station unit.

9. The fuel savings scoring system of claim 1, wherein the vehicle is a truck, a taxi, a van, or another commercial vehicle operated and managed by the commercial vehicle fleet company.

10. The fuel savings scoring system of claim 1, wherein the driving score motivates a driver of the vehicle to utilize non-mechanical improvement factors to improve an overall operating fuel efficiency of the vehicle.

11. The fuel savings scoring system of claim 1, wherein the driving score motivates the commercial vehicle fleet company to utilize mechanical and physical improvement factors to improve an overall operating fuel efficiency of the vehicle.

12. The fuel savings scoring system of claim 1, wherein fuel savings score analytics unit in the commercial vehicle fuel consumption analytics module also calculates and keeps track of driving score trends over a day, a week, a month, a year, or another set period of time.
