Abstract

The invention discloses a hybrid vehicle and a mode switching control method and device thereof. The mode switching control method comprises the following steps that when the mode of the hybrid vehicle is switched from a full electric mode to a hybrid power mode, an engine is controlled to be ignited and started, and the output torque of a second motor is controlled to reach the required torque of the hybrid vehicle before the rotating speed of the engine reaches the preset target rotating speed; and when the rotating speed of the engine reaches the preset target rotating speed, the engine and the second motor are controlled to simultaneously conduct torque output so that the mode of the hybrid vehicle can be switched into the hybrid power mode, specifically, the sum of the output torque of the second motor and the output torque of the engine is the required torque, accordingly, power interruption can be avoided when the mode of the hybrid vehicle is switched from the full electric mode to the hybrid power mode, the operation stability and smoothness of the vehicle are improved, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a mode switching control method of a hybrid electric vehicle, a mode switching control device of a hybrid electric vehicle and a hybrid electric vehicle. Background technique [0002] Due to the gradual shortage of non-renewable energy such as petroleum and the pollution of the atmosphere by the emissions of traditional vehicles, new energy vehicles are the trend of future vehicle development, and hybrid vehicles are a solution for new energy vehicles. In the hybrid electric vehicle in the related art, power interruption occurs during the process of switching from the pure electric EV mode to the hybrid HEV mode, which greatly reduces the handling stability and ride comfort of the vehicle. [0003] Therefore, related technologies need to be improved. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at leas...
