Abstract

The invention provides a driving mode control method of an extended-range electric vehicle, a control system thereof and a readable storage medium. The driving mode control method of the extended-range electric vehicle comprises the steps that detecting at least two system signals are detected, wherein any two system signals come from the same subsystem or two different subsystems of the extended-range electric vehicle; judging the size relationship between the detected at least two system signals and respective corresponding threshold conditions, and generating corresponding driving mode requests according to corresponding judgment results; and synthesizing all the driving mode requests, and selecting a corresponding driving mode for the extended-range electric vehicle. According to the technical scheme, the requirements of a driving system, a high-voltage battery system, a thermal management system, an engine system and other systems can be comprehensively considered, and then betterdriving performance, fuel economy and emission requirements are met.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a driving mode control method of an extended-range electric vehicle, a control system thereof, and a readable storage medium. Background technique [0002] Range-extended electric vehicles, as an ideal transitional model during the energy transition of vehicles, are currently favored by a large number of manufacturers. refer to figure 1 , figure 1 is a schematic diagram of the structure of an extended-range electric vehicle, from figure 1 As can be seen in the figure, the range-extender electric vehicle includes a transmission shaft 11, a drive motor 12, a battery 13 and a range extender 14, and the range extender 14 includes a relatively small engine 141 and a generator 142, and the range extender 14 is an auxiliary The power unit can assist in providing the energy required by the extended-range electric vehicle. [0003] By adding a range extender to traditional h...
