Abstract

A control method of a hybrid vehicle is provided and includes determining whether a current vehicle driving mode is an EV mode, whether a current vehicle driving state satisfies a kick-down shift condition, and whether the current vehicle driving state satisfies a driving mode conversion condition for conversion into an HEV mode. The engine is started when the kick-down shift and the driving mode conversion conditions are satisfied. A current motor speed and discharging power of the battery are measured. The measured motor speed and predetermined motor reference speed are compared based on discharging power of the battery. A transmission input shaft target speed for the kick-down shift is calculated and compared to a predetermined transmission input shaft target reference speed based on discharging power of the battery. A control order is determined based on the comparisons and the kick-down shift and the engagement of the engine clutch are performed.

Description

technical field

[0001] The present invention relates to a hybrid vehicle and a control method for the hybrid vehicle, and more particularly, the present invention relates to a hybrid vehicle and a control method thereof which are based on discharge of a battery when a downshift shift and engine clutch engagement are required. power to control downshifting and engine clutch engagement. Background technique

[0002] In recent years, electric vehicles and hybrid vehicles have been developed in improving the fuel consumption of vehicles. An electric vehicle refers to a vehicle in which driving torque is generated by an electric motor, and a hybrid vehicle refers to a vehicle in which driving torque is generated by an engine and an electric motor. A hybrid vehicle is driven in various modes (eg, electric mode, hybrid mode, engine mode, etc.) based on its driving conditions. The electric mode is a mode in which driving torque is generated by the electric motor, the hybrid mode i...
