The invention relates to a water spraying
control system of an automobile water spraying
windscreen wiper. The water spraying
control system comprises a
windscreen wiper motor, a washing pump, a first contact, a second contact, a third contact, a vehicle body controller and a
relay, wherein an insulating disc is fixed to a
motor shaft of the
windscreen wiper motor in the circumferential direction, a current-conducting plate is arranged on the insulating disc and is in a circular arc shape concentric with the insulating disc, the central angle of the current-conducting plate is smaller than or equal to 180 degrees, the front end of the conductive plate is in contact with the first contact, the second contact and the third contact, one end of the washing pump is electrically connected with a movable contact of the
relay, the other end of the washing pump is electrically connected with a negative
electrode of a vehicle body power supply, a first static contact of the
relay is connected with a common ground, a second static contact and a power supply end of the relay are electrically connected with a positive
electrode of the vehicle body power supply, a
signal control end of the relay is electrically connected with a
control signal output end of the vehicle body controller, the first contact is electrically connected with a reset
signal end of the vehicle body controller, the second contact is electrically connected with a negative
electrode of the vehicle body power supply, and the third contact is electrically connected with a
control signal input end of the automobile body controller.
