Embodiment Construction

[0020] It should be understood that the term "vehicle" or "vehicular" or other similar terms as used herein generally includes motor vehicles such as passenger cars (including sport utility vehicles (SUVs), buses, trucks, various commercial vehicles ), ships (including motorboats and ships of all kinds), aircraft, etc., and includes hybrid vehicles, electric vehicles, plug-in hybrid electric vehicles, hydrogen-powered vehicles and other alternative fuel vehicles (for example, vehicles derived from resources other than petroleum fuel). As referred to herein, a hybrid vehicle is a vehicle that has two or more sources of power, such as gasoline-powered and electric-powered vehicles.

[0021] Although the exemplary embodiments are described as using a plurality of units to perform the exemplary process, it should be understood that the exemplary process may also be performed by one or more modules. Additionally, it should be understood that the term controller / control unit refers...

Abstract

A battery discharge limit control system is provided. The system includes a motor driven by receiving the power stored in a battery and a clutch connected to the rotary shaft of the motor. Additionally, an engine includes the rotary shaft connected to the rotary shaft of the motor through the clutch and a transmission changes the rotational speed of the rotary shaft of the motor or the engine based on the input of the shift stage instruction to output the rotational speed to a driving wheel of a vehicle. A controller opens the clutch and drives the motor in the reverse rotation when the inputof the shift stage instruction is a reverse shift stage.

Description

technical field [0001] The present disclosure relates to battery discharge limit control systems and methods, and more particularly, to systems and methods for controlling the discharge limit of a battery that reversely drives an electric motor during reverse operation of a hybrid vehicle without the application of a separate reverse Gearbox. Background technique [0002] A hybrid vehicle is an eco-friendly vehicle that supplies driving force to the wheels by selectively using an engine for generating rotational force by burning fossil fuels, and an electric motor, depending on vehicle driving conditions or vehicle conditions, the electric motor Used to use electrical energy to generate rotational force. Generally, a hybrid vehicle includes an engine clutch for selectively connecting a rotation shaft of an engine and a rotation shaft of an electric motor, and the hybrid mode couples the engine clutch to supply the rotational force of the engine to the wheels, or to supply t...
