HYBRID VEHICLE AND SHIFTING CONTROL METHOD AND POWER TRANSMISSION SYSTEM THEREOF

摘要

A shifting control method for a hybrid vehicle includes: detecting operating parameters of the hybrid vehicle, where the operating parameters of the hybrid vehicle include vehicle speed, vehicle acceleration as reflected from an accelerator-pedal signal and a current gear of the hybrid vehicle; determining a work mode of the hybrid vehicle; performing speed adjustment and shifting control to a first motor-generator (51) according to the work mode and the operating parameters of the hybrid vehicle to implement shifting control of the hybrid vehicle, where the work mode includes an electric-vehicle mode and a hybrid-electric-vehicle mode. The method considers performing speed adjustment and shifting control under various working conditions. The method improves smoothness and comfort of the vehicle and enlarges the range of use. A power transmission system (100) of a hybrid vehicle and a hybrid vehicle is provided.
