Abstract

Parameters which change depending on driving method of a vehicle driver are inputted to a fuel consumption estimation model. This fuel consumption estimation model estimates fuel consumption of a vehicle based on the parameter. The fuel consumption of a vehicle estimated by the fuel consumption estimation model is outputted to an output portion.

Claims

1. A fuel consumption estimating unit comprising:

a fuel consumption estimation model configured to generate an estimated fuel consumption of a vehicle for a vehicle driver to be evaluated based on input parameters which change depending on the driving style of the vehicle driver to be evaluated; and

an output portion configured to output the estimated fuel consumption of the vehicle for the vehicle driver to be evaluated that is generated by the fuel consumption estimation model,

wherein the fuel consumption estimation model is configured based on extracted parameters which change depending on driving operations performed by a plurality of drivers on various road conditions and on real fuel consumption measurements during the driving operations,

wherein the extracted parameters include at least an engine revolution number of the vehicle when a vehicle transmission is shifted up, an accelerator opening degree when the vehicle is revving, and an engine revolution number change ratio of the vehicle,

wherein the fuel consumption estimation model estimates the fuel consumption of the vehicle based on the various road conditions and based on at least the engine revolution number when the vehicle transmission is shifted up, the accelerator opening degree, and the engine revolution number change rate, and

wherein the output portion outputs data denoting the fuel consumption of the vehicle estimated by the fuel consumption estimation model by means of a radio sending unit installed on the vehicle.
