Problems solved by technology

[0004] When the remaining fuel in the fuel tank has not been used for a considerable period of time, the fuel ages, and short chain fatty acids are produced in the aged fuel, which causes the fuel tank to corrode
Corrosion of engine drive components or reduced engine output when running the engine on aged fuel as described above

Abstract

The invention discloses a fuel management system for a hybrid vehicle and a control method thereof. The fuel management system for a hybrid vehicle driven by an electric motor and an internal combustion engine is provided. The system includes a check unit that detects a time in which the internal combustion engine was last operated and stores the detected time as an engine driving point in time. A controller receives the stored engine driving point in time and determines that a fuel remaining in a fuel tank is aged when a time period elapsing from the engine driving point in time reaches a set fuel leaving time period, to operate the internal combustion engine while the hybrid vehicle is driven.

Description

technical field [0001] The present invention relates to a fuel management system for a hybrid vehicle and a control method thereof capable of preventing corrosion of a fuel tank due to remaining fuel remaining unused in a hybrid vehicle for a considerable period of time when fuel is consumed. Background technique [0002] Generally, a hybrid vehicle, which is a vehicle driven by effectively combining two different types of drive sources, uses an engine and a motor generator. A hybrid vehicle uses an engine with good high-speed torque characteristics and a motor generator with good low-speed torque characteristics so that the vehicle is driven using the electric power of the motor generator as the main driving force when driven at a low speed, and when driven at a high speed Use the power of the engine as the main driving force to drive the vehicle. [0003] In addition, hybrid vehicles effectively combine the power of the engine and the electric power of the motor generator...
