Abstract

A method is provided for evaluating fuel consumption efficiency of a vehicle driven by a driver. The method comprises the steps of: a) collecting data associated with said driver'"'"'s driving performance from a plurality of sensors comprised in the vehicle; b) identifying a plurality of driving events based on the collected data; c) estimating the driver'"'"'s performance in at least one driving event from among the identified plurality of driving events, wherein that at least one event if poorly performed is associated with increased fuel consumption; and d) based on the estimated driver'"'"'s performance of the at least one driving event, evaluating a fuel consumption efficiency of the vehicle driven by that driver.

Claims

1. A method for evaluating fuel consumption efficiency of a vehicle driven by a driver, comprising:

a. collecting data associated with said driver'"'"'s driving performance from a plurality of sensors comprised in said vehicle;

b. identifying a plurality of driving events based on the data collected;

c. estimating the driver'"'"'s performance in at least one driving event from among the identified plurality of driving events, wherein that at least one event when poorly performed is associated with increased fuel consumption; and

d. based on the estimated driver'"'"'s performance of the at least one driving event, evaluating a fuel consumption efficiency of the vehicle driven by said driver.

2. The method according to claim 1, wherein the method further comprising:

e. providing said driver with real-time information associated with the vehicle fuel consumption based on the driver'"'"'s performance.

3. The method according to claim 1, wherein the step of evaluating the fuel consumption efficiency of the vehicle driven by said driver, takes into consideration data associated with a location and/or time and/or traffic condition and/or weather condition at which said at least one driving event took place.

4. The method according to claim 1, wherein said at least one driving event is a member selected from a group consisting of:

braking, braking while reaching a turn, accelerating, turning, acceleration while reaching a turn, acceleration while driving in a turn, braking while driving in a turn, sudden braking in a turn, accelerating while exiting a turn, braking while exiting a turn, lane crossing, braking profile, high rpm at which the vehicle is driven, timing of gear shifting, or any combination thereof.

5. The method according to claim 1, further comprising the steps of storing the evaluated fuel consumption efficiency of the vehicle driven by said driver, and providing said driver with data analysis and/or one or more recommendations regarding his driving performance based on said fuel consumption efficiency that had been stored.

6. A device for evaluating fuel consumption efficiency of a vehicle driven by a driver and comprising:

a. a plurality of sensors comprised in said vehicle, adapted to collect data associated with said driver'"'"'s driving performance; and

b. a processor adapted to;

(i) identify a plurality of driving events based on the collected data;

(ii) estimate the driver'"'"'s performance in at least one driving event that when poorly performed is associated with increased fuel consumption, from among the plurality of identified driving events; and

(iii) evaluate the fuel consumption efficiency of the vehicle driven by said driver.

7. The device according to claim 6, further comprising a display means to enable providing the driver with real time feedback that relates to the vehicle fuel consumption based on the driver'"'"'s performance.

8. The device according to claim 6, further comprising storage means for storing the evaluated fuel consumption efficiency of the vehicle driven by said driver, and wherein said processor is further adapted to provide one or more recommendations regarding the driver'"'"'s driving performance based on said fuel consumption efficiency that had been stored.

9. A computer program product encoding a computer program stored on a non-transitory computer readable storage medium for executing a set of instructions by a computer system comprising one or more computer processors for carrying out a process for evaluating fuel consumption efficiency of a vehicle driven by a driver, and comprising the steps of:

collecting from a plurality of sensors comprised in the vehicle, data associated with the driver'"'"'s driving performance;

identifying a plurality of driving events based on the data collected;

estimating the driver'"'"'s performance in at least one driving event from among the identified plurality of driving events, wherein that at least one event when poorly performed, is associated with increased fuel consumption; and

based on the estimated driver'"'"'s performance of the at least one driving event, evaluating a fuel consumption efficiency of the vehicle driven by the driver.

10. The computer readable medium according to claim 9, wherein the set of instructions further comprising instructions to provide the driver with real-time information associated with the vehicle'"'"'s fuel consumption based on the driver'"'"'s performance.
