A kind of method for estimating vehicle Fuel Consumption, described method comprises the steps: parameter estimation rolling power component, aerodynamic drag component and the component of acceleration by using at least one to obtain from the onboard diagnostic system of vehicle, thereby estimates the overall power of described vehicle; Determine the type of the fuel of described vehicle use; And by the described component summation to described overall power and again divided by the efficiency value of the energy value of described fuel type and predetermined engine, thereby estimate described Fuel Consumption. |
