Operating mode control system and control method based on hybrid vehicle

The invention provides an operating mode control system based on a hybrid vehicle. Multiple operating modes are set in the control system, power thresholds of a power battery corresponding to the operating modes are different, in different operating modes, a judgment unit compares SOC of the power battery and the speed of the vehicle with power thresholds and speed thresholds in the operating mode, and selects a driving mode according to a comparison result; the control system can control the driving mode of the hybrid vehicle according to the needs of a driver, meet different demands while taking power performance and economical efficiency into account, reduce energy consumption, and improve harmony between human, vehicles and the environment.
