| description | The present invention relates to a system and method for controlling an LPG fuel pump and the fuel supply system of an LPI engine using the same, wherein the method for controlling an LPG fuel pump includes: driving the motor of the LPG fuel pump with voltage at a predetermined duty; measuring the rpm (revolutions per minute) of the motor; changing the duty of the motor in order to allow the measured rpm of the motor to reach a predetermined target rpm; measuring the pressure of an LPG bombe and the pressure of an injector; and changing the target rpm in order to maintain a difference between the measured pressure of an LPG bombe and the pressure of an injector into a predetermined value. [Reference numerals] (200) Sensor type BLDC motor;(300) Motor controller;(400) Pressure signal #1 (engine side);(500) Pressure signal #2 (bomb side);(700) Power supply;(AA) Command signal;(BB) Control �P = 5bar following voltage duty control;(CC) Diagnostic signal;(DD) Receive rotor location signal (hall sensor signal 3EA) |
