Problems solved by technology
[0003] However, in the actual road operation, the environmental conditions, road conditions, road conditions, testing equipment, driver level and vehicle load will cause differences in the test results; but in the laboratory, the test conditions are relatively fixed, and the test results fluctuate little, but Due to the difference between the test conditions and the actual situation, the measurement results in the laboratory are inconsistent with the user experience when running on the actual road, so the detection accuracy is not high

Embodiment Construction
[0023] The principles and features of the present invention will be described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0024] In the present invention, the test is divided into two parts, the reference stage and the test stage. During the measurement in the reference stage, all the conditions of the test vehicle do not change. During the measurement in the test stage, only the energy consumption of the test vehicle is changed to be measured. The technology changes, the two stages get a certain number of energy consumption ratios, if the technology changes lead to changes in energy consumption, the energy consumption ratio of the test stage will change compared with the baseline stage; calculate the variance of the two stages , use the hypothesis test to judge whether the variances of the ratio of energy consumption in the two sta...

The invention discloses a method and system for detecting vehicle energy consumption changes, and relates to the technical field of vehicles. The method comprises the following steps: enabling a reference vehicle and at least one test vehicle to run for the same distance of preset times under the same initial condition; after driving is completed, obtaining the initial energy consumption ratio of each test vehicle to the reference vehicle; changing the initial condition, so that the reference vehicle travels for a preset number of times for the same distance according to the initial condition and each test vehicle according to the changed initial condition; after driving is completed, obtaining the test energy consumption ratio of each test vehicle to the reference vehicle; and performing F hypothesis test analysis on the initial energy consumption ratio and the test energy consumption ratio to obtain the relationship between the change of the initial condition and the energy consumption change of the test vehicle. The method is suitable for detecting the energy consumption change of the vehicle, the measurement result is consistent with the user feeling when the vehicle runs on an actual road, and the measurement accuracy is improved.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a method and system for detecting changes in vehicle energy consumption. Background technique [0002] At present, with the popularization and growth of vehicles, new technologies and means for energy saving, emission reduction and energy consumption reduction have been developed and applied on a large scale. In order to confirm the energy-saving effect, testing is usually required. The current testing methods are mostly carried out in the laboratory. For example, in the emission laboratory, the chassis dynamometer, emission analyzer and environmental chamber operation test are used for cyclic measurement. [0003] However, in the actual road operation, the environmental conditions, road conditions, road conditions, testing equipment, driver level and vehicle load will cause differences in the test results; but in the laboratory, the test conditions are relatively fixed, and the...
