Problems solved by technology

[0002] At present, as a new type of hybrid electric vehicle, plug-in hybrid electric vehicle (English: Plug-inHybrid Electric Vehicle, PHEV for short), although the power battery pack capacity of PHEV is large, it can provide users with a long mileage, but , different from traditional hybrid vehicles, after the power of PHEV is exhausted, the power battery pack cannot be charged by the engine. Therefore, it is necessary to make a reasonable and accurate assessment of the remaining power of the power battery pack when using PHEV

Embodiment Construction

[0061] The energy consumption of a PHEV is not only affected by the PHEV model, but also by the driving behavior of the user. The relationship between the energy consumption of the PHEV and the driving behavior of the user is due to the randomness and uncertainty of the driving behavior, as well as the abnormality of the vehicle system. Linearity makes it difficult to quantify the relationship between PHEV energy consumption and user driving behavior.

[0062] At present, the method of statistics and analysis based on a large amount of driving behavior and energy consumption data and the experimental verification of the statistical analysis results can show the connection between energy consumption and driving behavior to a certain extent. However, this method needs to traverse all Carrying out a large number of experiments on factors that affect energy consumption, such as driving behavior and external factors, is not only time-consuming and labor-intensive, but also the corre...

Abstract

The embodiment of the invention discloses an energy consumption simulation method and device based on driving behaviors, and the method comprises the steps: constructing a sample database according tocollected driving behavior data which comprises a plurality of groups of driving behavior features; performing principal component analysis PCA processing on the sample database to obtain a principalcomponent score matrix, and determining principal components according to the principal component score matrix; a target speed curve is obtained by processing the principal components, and the targetspeed curve is a curve obtained by fitting the collected driving behavior data; and simulating the target speed curve to obtain simulation energy consumption corresponding to the driving behavior. Thus, for any driving behavior of the driver, the energy consumption corresponding to the driving behavior can be effectively simulated, quantification of the corresponding relation between the drivingbehavior and the energy consumption is achieved, and therefore the actual driving behavior of the user can be guided in a targeted mode according to the simulation result, and a reference basis is provided for the good and low-energy-consumption driving behavior.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a driving behavior-based energy consumption simulation method and device. Background technique [0002] At present, as a new type of hybrid electric vehicle, plug-in hybrid electric vehicle (English: Plug-inHybrid Electric Vehicle, PHEV for short), although the power battery pack capacity of PHEV is large, it can provide users with a long mileage, but , Different from traditional hybrid vehicles, after the power of PHEV is exhausted, the power battery pack cannot be charged by the engine. Therefore, it is necessary to make a reasonable and accurate assessment of the remaining power of the power battery pack when using PHEV. [0003] Since there is a certain correlation between the driving behavior of the driver and the energy consumption of the PHEV power battery pack, good driving behavior may consume less energy consumption of the power battery pack; The energy consumption of...
