METHOD OF PROGRAMMED CONTROL OF AUTOMOBILE WINDSHIELD WIPING AND WASHING PROCESS Russian patent published in 2000 - IPC

FIELD: transport engineering. SUBSTANCE: proposed method provides control of windshield wiper and washer. One-time operation mode is provided with either single or double stroke of windshield wiper blades without switching washer pump or with triple stroke of blades at short time switching on of pump, or constant synchronized operation of blades and pump, and standard intermittent mode of operation with single of blades through preset time interval, programmed repeated operation mode with simultaneous multiple-stroke operation of blades and multiple switching- on of pump, standard continuous mode with continuous operation of blades and programmed multiple switching on of pump, accelerated continuous mode with continuous operation of blades and manual control of pump. Proposed method is implemented by means of windshield washer pump switch, wind-shield wiper change-over switch and programmable microcontroller. EFFECT: facilitated operation with provision of adequate observation of road at improved efficiency of control. 15 cl, 1 dwg
