Abstract

An apparatus and method of controlling a fuel pump of a hybrid electric vehicle may prevent the frequent on / off operations of a fuel pump relay that is configured to control the connection between a fuel pump controller and a power source, thereby ensuring the durability of the fuel pump relay.

Description

technical field [0001] The invention relates to a device for controlling a fuel pump of a hybrid electric vehicle. More particularly, the present invention relates to a device capable of preventing frequent on / off operations of a fuel pump relay configured to control a connection between a fuel pump controller and a power source, ensuring durability of the fuel pump relay. A device that controls the fuel pump of a hybrid electric vehicle. Background technique [0002] Generally, a fuel pump controller is installed in a hybrid electric vehicle to improve fuel efficiency, and an engine controller controls the operation of a fuel pump relay to turn on or off a fuel pump of the hybrid electric vehicle. The fuel pump relay is configured to control the electrical connection between the fuel pump controller and the power source. [0003] In a conventional hybrid electric vehicle, when the engine is stopped, the engine controller turns off the fuel pump relay, thereby stopping pow...
