The present invention provides a driving mode control method of an extended-range electric vehicle, its control system and a readable storage medium. The driving mode control method of the extended-range electric vehicle includes: detecting at least two system signals, and any two The above system signals come from the same subsystem or two different subsystems of the extended-range electric vehicle; judge the magnitude relationship between the detected at least two of the system signals and their corresponding threshold conditions, and according to the corresponding judgment results generating a corresponding driving mode request; and, combining all the driving mode requests, selecting a corresponding driving mode for the extended-range electric vehicle. The technical solution of the present invention can comprehensively consider the requirements of the drive system, high-voltage battery system, thermal management system, and engine system, thereby achieving better driving performance, fuel economy, and emission requirements.
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 and a readable storage medium thereof. Background technique [0002] As an ideal transition model during the transition of vehicle energy, extended-range electric vehicles are currently favored by the majority of manufacturers. see figure 1 , figure 1 is a schematic diagram of the structure of an extended-range electric vehicle. figure 1 As can be seen from the figure, the extended-range electric vehicle includes a transmission shaft 11, a drive motor 12, a battery 13 and a range extender 14. The range extender 14 includes a relatively small engine 141 and a generator 142. The range extender 14 is an auxiliary A power unit that can assist in providing the energy required for extended-range electric vehicles. [0003] By adding a range extender to a traditional hybrid electric vehic...
