摘要： A voltage divider circuit is configured by a resistor having one end connected to a positive electrode of a battery configuring a power source and another end connected to a first terminal that is a motor terminal on one side of a wiper motor, and a FET having one end connected to the first terminal and another end grounded. The voltage divider circuit lowers a voltage of the battery to a test voltage that does not cause the wiper motor to rotate. A microcomputer detects a detected voltage that is a voltage output from the voltage divider circuit to a second terminal that is a motor terminal on the other side of the wiper motor via the first terminal of the wiper motor and the wiper motor, and computes a motor terminal voltage, this being a potential difference between the first terminal and the second terminal, from the detected voltage.

摘要： A sensor assembly includes a cylindrical sensor window defining an axis, and an annular member coupled to the sensor window and rotatable about the axis. The annular member includes a nozzle aimed at the sensor window and oriented at an acute angle from a radial direction toward the axis in a plane orthogonal to the axis.

摘要： This disclosure details vehicle windshield wiper systems and methods for controlling windshield wipers in a manner that reduces the buildup of frozen precipitation on the vehicle windshield. In exemplary embodiments, a windshield wiper can be automatically commanded to wipe a windshield at a pre-calculated wiping interval rate when precipitation is detected on a vehicle surface, a vehicle ambient temperature is below a predefined ambient temperature threshold, and a vehicle interior temperature exceeds a predefined interior temperature threshold.

摘要： A vehicle wiper control apparatus monitors whether warpage occurs in a wiper strip made of a rubber-elastic material that is provided in a wiper blade. When a wiper of a vehicle is turned off and the warpage occurs in the wiper strip, the control apparatus controls the wiper mechanism to move the wiper blade to a parking position thereby preventing deformation of the wiper strip and maintaining the performance thereof.

摘要： An interior windshield wiper apparatus for cleaning the interior of an automobile windshield includes a housing with a pair of wiper apertures extending therethrough. An engagement member is coupled to the housing to selectively engage a dashboard of a vehicle adjacent a windshield. An electric motor is coupled within the housing. A gearbox and a wiper linkage are coupled to the electric motor to drive a pair of wiper arms. The wiper arms are pivotably coupled to the housing and extends through the pair of wiper apertures. A pair of wiper blades is coupled to the pair of wiper arms to clean the windshield of the vehicle as the pair of wiper arms pivots. A wiper button is coupled to the housing to activate the movement of the pair of wiper arms.

摘要： A wiper motor control circuit carries out control in which a driving circuit generates, and supplies to a wiper motor, a voltage that eliminates deviation between a target speed and an actual speed of an output shaft. In a case in which a state in which the deviation between the target speed and the actual speed is greater than or equal to a predetermined threshold value continues for a predetermined time or more, the wiper motor control circuit carries out control that lowers the target speed and in which the driving circuit generates, and supplies to the wiper motor, a voltage that eliminates deviation between the lowered target speed and the actual speed of the output shaft.

摘要： Provided are a rotor, a motor, and a wiper motor. An arc center of an outer circumferential surface of a rotor core and an arc center of an inner circumferential surface of a permanent magnet are off-centered radially outward from a rotational axis, with the circumferential center disposed on the radially outermost side. An angle formed by salient pole side surfaces facing each other of circumferentially adjacent two salient poles is equal to an angle formed by magnet side surfaces on both sides circumferentially of the permanent magnet. When the distance between the outer circumferential surface of the rotor core and the radially outermost end of the salient poles is Lt, and the distance between the inner circumferential surface of the permanent magnet and the radially outermost end of the magnet side surfaces is Lme, the distances Lt, Lme are set such that the relationship Lme

摘要： A windshield wiper cleaning assembly for dislodging debris from a wiper blade includes a housing that is attachable to a windshield wiper arm on a vehicle. A plunger unit is movably integrated into the housing and the plunger unit is urged outwardly from the housing when the plunger unit is turned on. The plunger unit abuts the windshield when the plunger unit is turned on thereby facilitating the arm of the windshield wiper to be urged away from the windshield. Moreover, the plunger is biased to retract into the housing after the plunger unit is turned on thereby facilitating a wiper blade on the windshield wiper arm to strike the windshield. In this way debris can be dislodged from the wiper blade.
