METHOD AND SYSTEM FOR CONTROLLING FUEL PUMP OF LPI CAR

摘要

PURPOSE: A method and system for controlling a fuel pump of a LPI vehicle is provided to control the RPM of a fuel pump by operating the fuel pump with a final driving signal of the corrected fuel pump. CONSTITUTION: A system for controlling a fuel pump of a LPI vehicle comprises a fuel pump(50) and a fuel pump control device. The fuel pump discharges the liquid fuel of the fuel tank part to a gas injector through the control of an ECU(Engine Control Part, 10). The fuel pump control device generates a driving signal for controlling the fuel pump. A drive signal operator computes the driving signal for controlling the fuel pump according to a target rotation speed value.
