A vehicle fuel consumption evaluation method and device

Abstract

The invention provides a vehicle fuel consumption evaluation method and device. The method comprises the steps of acquiring N pieces of driving behavior data to determine an evaluation object set; acquiring the evaluation weight value and the membership evaluation vector corresponding to each piece of driving behavior data in the N pieces of driving behavior data; constructing evaluation weight vectors based on the evaluation weight values corresponding to the N pieces of driving behavior data acquired by an acquiring module, performing normalization processing on the evaluation weight vectors, and constructing a membership evaluation matrix by using the membership evaluation vector corresponding to each piece of driving behavior data as a row vector; acquiring an evaluation result vector according to an evaluation weight vector obtained after normalization processing and a membership evaluation matrix obtained after normalization processing, and determining the current fuel consumption level of a vehicle according to the evaluation result vector. By collecting, analyzing and calculating driving behavior data, the fuel economy, namely the fuel consumption level, of a vehicle can be graded; the method and the device can solve the problem of excessive fuel consumption caused by bad driving behavior.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle fuel consumption evaluation method and a vehicle fuel consumption evaluation device. Background technique [0002] With the continuous development of the automobile industry and the continuous rise of oil prices, the fuel economy of vehicles has been widely concerned by vehicle drivers. Relevant studies have shown that under the same vehicle conditions, the driver's driving behavior is a key factor affecting the vehicle. [0003] Related technologies have proposed the following two evaluation methods for driving behaviors. One is to compare the driving behaviors collected from vehicles by establishing a database of bad driving behaviors, and evaluate the driving behaviors according to the comparison results. The other is to evaluate the driver's driving behavior from the perspective of safety; the other is to compare the single fuel consumption of a certain driving wi...

[0003] Related technologies have proposed the following two evaluation methods for driving behaviors. One is to compare the driving behaviors collected from vehicles by establishing a database of bad driving behaviors, and evaluate the driving behaviors according to the comparison results. The other is to evaluate the driver's driving behavior from the perspective of safety; the other is to compare the single fuel consumption of a certain driving with the real-time fuel consumption, and evaluate the fuel economy of driving behavior according to the comparison results. However, its disadvantages are: Unable to evaluate the impact of specific driving behavior on fuel consumption
