Embodiment Construction

[0028] It is to be understood that the terms "vehicle" or "vehicle" or other similar terms as used herein include motor vehicles in general, such as including sport utility vehicles (SUVs), buses, vans, various Passenger cars for commercial vehicles, ships including ships and ships of all kinds, aircraft, etc., and including hybrid vehicles, electric vehicles, hybrid electric vehicles, hydrogen-powered vehicles, and other alternative fuel vehicles (e.g., derived from sources other than petroleum fuel obtained from). As referred to herein, a hybrid vehicle is a vehicle having two or more sources of power, such as both gasoline-powered vehicles and electric-powered vehicles.

[0029] Although the example embodiments are described as using multiple units to perform the example process, it will be appreciated that the example process may also be performed by one or more modules. Additionally, it is to be understood that the term controller / control unit refers to a hardware device...

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...
