Single-vehicle air conditioner energy consumption prediction method and prediction device based on working condition recognition

Abstract

The invention provides a single-vehicle air conditioner energy consumption prediction method and prediction device based on working condition recognition. The method comprises the steps: firstly obtaining current environment temperature information, calculating the average speed, average acceleration and average idle speed duration of the current working condition, and obtaining the feature information of the current working condition; obtaining cold start energy consumption f1 of the current working condition; obtaining the air conditioner energy consumption f2 of the idle speed segment; obtaining the air conditioner energy consumption f3 of the current working condition motion segment; finally obtaining a temperature correction factor k; and weighting the f1, the f2 and the f3 to obtain the comprehensive energy consumption of the air conditioner under the current working condition. According to the single-vehicle air conditioner energy consumption prediction method and prediction device based on working condition recognition, remote transmission data generated in the actual driving process of a user is used as the basis, a traditional method for actual road collection is replaced, and obvious advantages exist in the aspects of the data coverage range, the collection period and the collection cost; and the air conditioner energy consumption can be accurately estimated, and support is provided for energy-saving driving and government supervision.

Description

Technical field [0001] The present invention belongs to the field of transportation, in particular, to a single-vehicle air conditioning energy consumption prediction method and a predictive device based on working conditions recognition. Background technique [0002] In 2019, my country's crude oil rose to 70.8%, of which car fuel consumption accounted for more than 70% of the oil consumption. Saving fossil energy, reducing car exhaust emissions, is a problem that must face and solve the automotive industry. Air conditioning is a key factor affecting the actual energy consumption of users. For traditional passenger cars, the energy consumption of air conditioners in summer is significantly increased, and the energy consumption increases by about 30%. For pure electric passenger cars, the air conditioner energy consumption in winter increases by more than 40%. [0003] In order to reflect the impact of air conditioning on the energy consumption of the vehicle, it is encouraged th...
