Sub- water pump sends pulse-width signal；After electronic water pump receives pulse-width signal, microcontroller therein passes through phase change logic
Pulse-width signal is applied on the electronic switch in electronic water pump by control, so as to be driven to the motor of electronic water pump.
The major defect of this method is：(1) electronic water pump is passively to receive pulse-width signal and be directly used in driving
Motor, microcontroller therein are only capable of driving motor rotation, but can not the actual speed of motor be fed back to host computer, therefore also
It is difficult to closed-loop control is accomplished to the rotating speed of motor；(2) it is frequently necessary in automobile simultaneously using multiple electronic water pumps, but if wanting to use
Host computer controls multiple electronic water pumps simultaneously, then needs to carry out multichannel pulse-width signal output, this needs to set more hard
Part interface, causes cost to increase.
