Abstract

The invention discloses an electric car driving range evaluation method based on working condition identification and fuzzy energy consumption. The electric car driving range evaluation method is established based on working condition identification and fuzzy energy consumption and includes the steps of dividing working conditions based on fuzzy C mean value cluster algorithm to obtain parameters for identifying working conditions, establishing a fuzzy rule base between characteristic parameters and energy consumption, optimizing driving mileage L with kilometer as the unit, and estimating residual driving range Srest. The method combines working condition identification and energy consumption modeling, obtains related information of an electric car on a real-time basis, and is rarely affected by external factors such as ambient temperature and vehicle driving states. Energy consumption is further divided in to a certain level, so that real energy consumption under certain speed can be reflected.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a method for estimating the driving range of electric vehicles based on working condition identification and fuzzy energy consumption. Background technique [0002] With the rapid increase in the number of traditional fuel vehicles, the environmental pollution caused by fuel vehicles and the problem of global fuel depletion are also becoming more and more serious. Due to the advantages of environmental protection and energy saving, electric vehicles have attracted more and more attention, but because of their limited driving range, they have been widely promoted. In order to improve the convenience of using electric vehicles, it is necessary not only to improve the mileage, but also to study the real-time monitoring of the status of electric vehicles and the real-time estimation of the mileage, so as to provide accurate vehicle information for drivers. The driving rang...
