초록 ▼

A controller for a vehicle fuel pump electric motor is connected to one or more vehicle sensors for sensing fuel flow demand and pulse width modulating the motor to control the speed. A fuel demand sensor and a triangle generator are connected to a summing controller for generating a pulse width modulated control signal to a driver. The driver has a pair of outputs for generating a pair of complementary pulse width modulated switch signals to a pair of switches whereby the switches are switched on and off alternately. One of the switches is connected in series between a power supply and the motor armature and the other switch is connected across the armature. A crash sensor, such as an inertia switch, is connected to the summing controller for terminating pulse width modulation in the event of a crash. The switch connected across the armature can be turned on to short circuit the armature and quickly stop the motor in the event of a crash.

대표청구항 ▼

An apparatus for controlling a fuel pump electric motor powered from a direct current power source comprising: a first input line for receiving a demand signal representing a fuel flow demand of a vehicle engine; a controller having a first input connected to said first input line and an output and being responsive to said demand signal for generating a pulse width modulated control signal at said controller output; a crash sensor for sensing a crash condition for a vehicle and having an output for generating a crash detection signal representing a crash condition and a second input line connected to said crash sensor output and wherein said controller has a second input connected to said second input line; a driver having an input connected to said controller output and an output and being responsive to said control signal for generating a switch signal at said driver output; and a switch having a gate input connected to said driver output, a power input and a power output whereby when said switch power input is connected to a direct current power supply and said switch power output is connected to a direct current fuel pump electric motor, said switch controls the speed of said motor in response to said demand signal, and wherein said controller is responsive to said crash detection signal for turning off said switch when said crash sensor senses a crash.
