Abstract

Parameters having a correlation with a crowded condition of a road traveled by a vehicle are inputted to an ideal fuel consumption estimation model. This ideal fuel consumption estimation model estimates an ideal fuel consumption of vehicle based on the parameters. The ideal fuel consumption of vehicle estimated by the ideal fuel consumption estimation model is outputted to an output portion.

Claims

1. A fuel consumption estimating unit of vehicle comprising:

an ideal fuel consumption estimation model configured to estimate an ideal fuel consumption of the vehicle with parameters having a correlation with road condition under which the vehicle runs inputted; and

an output portion configured to output the ideal fuel consumption of the vehicle estimated by the ideal fuel consumption estimating model.

2. The fuel consumption estimating unit of vehicle according to claim 1, wherein

the parameter includes an average vehicle speed of the vehicle, frequency of stops and idling ratio and

the ideal fuel consumption estimating model is configured to estimate the ideal fuel consumption of the vehicle with at least the average vehicle speed of the vehicle, frequency of stops and idling ratio inputted.

3. The fuel consumption estimating unit of vehicle according to claim 1, further comprising:

a real fuel consumption measuring portion configured to measure a real fuel consumption of the vehicle, wherein

the output portion is configured to output the ideal fuel consumption of the vehicle estimated by the ideal fuel consumption estimation model and the real fuel consumption of the vehicle measured by the real fuel consumption measuring portion.

4. The fuel consumption estimating unit of vehicle according to claim 3, wherein

the output portion displays the ideal fuel consumption and the real fuel consumption at the same time on a display unit installed on the vehicle.

5. The fuel consumption estimating unit of vehicle according to claim 3, further comprising:

a sending unit configured to send the ideal fuel consumption of the vehicle estimated by the ideal fuel consumption estimating model and the real fuel consumption of the vehicle measured by the real fuel consumption measuring portion to outside by radio.
