  • INTEGRATED PWM FUEL PUMP DRIVER MODULE
    Publication number: 20150176551
    Abstract: In accordance with an aspect of the present disclosure, an integrated PWM fuel pump driver module includes a circuit board on which at least one power semiconductor is disposed and a fuel tube downstream of a fuel pump controlled by the driver module. The fuel flowing through the fuel tube cools each power semiconductor as heat is transferred from each power semiconductor into the fuel.

  • Thermistor-based fuel sensor
    Patent number: 7698939
    Abstract: A system for sensing a fuel level includes sensors that sense the fuel level and a voltage source that applies a constant voltage to the sensors for a predetermined time. The system includes a control module that measures outputs of the sensors at a beginning and at an end of the predetermined time. The control module determines a number of the sensors that are submersed in fuel or air based on the outputs and calculates the fuel level based on the number of the sensors that are submersed in fuel or air.

  • Fuel pump speed control system
    Patent number: 7509945
    Abstract: A fuel pump controller includes a detecting device for detecting environmental vibrational energy and converting the environmental vibrational energy into an electrical signal. A motor controller is coupled to a fuel pump motor wherein the electrical signal is used by the controller to command the fuel pump motor to operate at one of a plurality of speeds wherein the commanded speed is at least in part a function of the environmental vibrational energy.
