Patent Images
1. A device to evaluate how economically a vehicle is being driven, comprising:
- an obtaining unit configured to obtain at least one physical parameter and to determine, at any given time, a value of a speed and a value of an instantaneous acceleration of a traveling vehicle;
a calculation and comparison unit configured to calculate, from the at least one physical parameter, an effective parameter that depends on the instantaneous acceleration and to compare the effective parameter with a reference parameter;
a driving evaluation unit configured to generate a driving energy score, by measuring a variance between the effective parameter and the reference parameter, wherein the driving energy score for the vehicle is solely or mostly related to how the vehicle is being driven, and is not solely or mainly related to fuel consumption linked to a vehicle engineering feature, and wherein generating the driving energy score includes removing the effects specific to the vehicle and those of the outside ambient conditions; and
a display unit configured to display the driving energy score.

8. A process to evaluate how economically a vehicle is being driven, comprising the following steps:
-
obtaining, by an obtaining unit configured to obtain, at least one physical parameter, wherein it is possible, at any given time, to determine a value of a speed and a value of an instantaneous acceleration of a traveling vehicle; calculating, by a calculation and comparison unit configured to calculate, an effective parameter from the at least one physical parameter, wherein the effective parameter depends on the instantaneous acceleration or the speed of the vehicle; comparing, by a calculation and comparison unit configured to compare, the calculated effective parameter with a reference parameter; generating, by a driving evaluation unit configured to generate, a driving energy score according to a variance between the effective parameter and the reference parameter, wherein the driving energy score is solely or mainly related to how economically the vehicle is being driven, and is not solely or mainly related to fuel consumption linked to a vehicle engineering feature, and wherein generating the driving energy score includes removing the effects specific to the vehicle and those of the outside ambient conditions; and displaying, by a display unit, the driving energy score. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
