Abstract: 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.
