Claims (1)

СРЕДСТВА Сигнал с генератора 1 ультразвука подаетс  на излучатель 2 ультразвука, ультразвуковые колебани  с которого распростран ютс  по лобовому стеклу 4, улавливаютс  приемником ультразвука и преобразуютс  Б электрические колебани  в блоке 3. СУни проход т через фильтр 5 верхних частот, который отфильтровывает низкочастотные паразитные сигналы , возникающие в результате вибрации транспортного средства, и поступают на пороговый элемент б, управл ющий сигнал с которого подаетс  в цепь 7 управлени  двигателем стеклоочистител . В случае наличи  мешающей пленки из воды, пыли, гр зи и т. п., часть ультразвуковой волны поглощаетс  этой пленкой. Приемник ультразвука воспринимает в этом случае сигнал меньший, чем поступивший на лобовое стекло, а преобразователь преобразует его в электрический сигнал, поступающий на пороговый элемент, управл ющий сигнал с которого поступает в цепь управлени  двигателем стеклоочистител , вызыва  его срабатывание. Предлагаемое устройство автоматического управлени  двигателем стеклоочистител  транспортного средства повышает эффективность использовани  стеклоочистител , не требует у водител  времени на его обслуживание в работе и позвол ет снизить аварийность на транспортных магистрал х. Формула изобретени  Устройство автоматического управлени  двигателем стеклоочистител  транспортного средства, содержащее узел контрол  наличи  осадков на лобовом стекле, преобразователь и пороговый элемент, включенный в цепь управлени  двигателем стеклоочистител , отличающеес  тем, что, с целью повышени  эффективности использовани  устройства , узел контрол  наличи  осадков на лобовом стекле содержит генератор, излучатель ультразвука, установленный с одной боковой стороны внутренней поверхности лобового стекла, и приемник ультразвука, установленный с противоположной по отношению к излучателю боковой стороны лобового стекла и соединенный последовательно с преобразователем, причем устройство снабжено фильтром верхних частот, вход которого соединен с выходом преобразовател , а выход - со входом порогового элемента . Источники информации, прин тые во внимание при экспертизе 1. Патент Великобритании № 1116401, кл. В 60 S 1/08, 1968 (прототип).MEANS The signal from ultrasound generator 1 is fed to ultrasound emitter 2, the ultrasonic oscillations from which propagate through the windshield 4, are picked up by the ultrasound receiver and the electrical oscillations in block 3 are converted. Suni passes through the high-pass filter 5, which filters out low-frequency spurious signals, resulting from vehicle vibrations, and fed to threshold element b, the control signal from which is fed to the wiper motor control circuit 7. In the case of the presence of an interfering film of water, dust, dirt, etc., part of the ultrasonic wave is absorbed by this film. In this case, the ultrasound receiver perceives a signal smaller than that supplied to the windshield, and the transducer converts it into an electrical signal that arrives at the threshold element, the control signal from which enters the wiper motor control circuit, causing it to trigger. The proposed automatic engine control device for a vehicle wiper increases the efficiency of use of the wiper, does not require the driver time to maintain it and reduces the accident rate on the main roads. Claims An automatic engine control device for a vehicle windshield wiper, comprising a precipitation control unit on the windshield, a transducer and a threshold element included in the wiper motor control circuit, characterized in that, in order to improve the use efficiency of the device, the precipitation control unit on the windshield contains a generator, an ultrasound emitter mounted on one side of the inner surface of the windshield, and an ultrasound receiver Sound mounted opposite to the radiator side of the windshield and connected in series with the converter, wherein the device is provided with a highpass filter having an input connected to the output transducer, and an output - to the input of the threshold element.
