Hybrid vehicle model energy management mode switching method and device, equipment and medium

Abstract

The invention relates to a hybrid vehicle model energy management mode switching method, device and equipment and a medium. The method comprises the steps that an electric energy supply condition is acquired; total energy consumption information is determined based on the obtained total mileage and historical stroke energy consumption; current remaining total electric energy information is obtained; based on the total energy consumption information and the total electric energy information, whether a stroke higher than a preset energy consumption demand exists or not is judged; and the energymanagement mode is determined based on the electrical energy supply condition and whether there is a stroke higher than the preset energy consumption demand. The technical scheme of the embodiment cansolve the problems that for a user, the mode selection difficulty is high; and if the user selects an improper energy management mode, the dynamic property, the economical property and the NVH performance of the vehicle are greatly different from those expected by the user. Namely, the energy management mode can be intelligently and automatically switched according to the electric energy supply condition and whether the vehicle has the stroke higher than the preset energy consumption demand or not, so that the user does not need to independently select the energy management mode, and the dynamic property, economical property and NVH performance requirements can be met.

Description

technical field [0001] The present disclosure relates to the technical field of energy management of hybrid vehicles, and in particular to a method, device, equipment and medium for switching energy management modes of hybrid vehicles. Background technique [0002] In recent years, with the continuous development of society and the continuous improvement of people's living standards, people's demand for cars has also increased. Due to the shortage of energy and the environmental pollution caused by traditional cars, the Electric vehicles came into being. Although pure electric vehicles have the characteristics of zero emission and zero pollution, due to the inability to effectively increase the energy density of power batteries at this stage, the power of pure electric vehicles cannot meet people's needs. However, hybrid vehicles (also known as " The emergence of hybrid vehicles") has solved this problem to a certain extent: hybrid vehicles use a fuel-electric power mode, w...

AI Technical Summary

Problems solved by technology

Although pure electric vehicles have the characteristics of zero emission and zero pollution, due to the inability to effectively increase the energy density of power batteries at this stage, the power of pure electric vehicles cannot meet people's needs. However, hybrid vehicles (also known as " The emergence of hybrid electric vehicles") has solved this problem to a certain extent: hybrid vehicles adopt a fuel-electric power mode, which can use fuel combustion to supplement power when the battery power is insufficient.

As a result, it is difficult for the user to choose a mode; and if the user chooses an inappropriate energy management mode, the vehicle's power performance, economy, and noise, vibration, and harshness (Noise, Vibration, Harshness, NVH) There is a large gap between performance and user expectations
