Abstract
Nel caso di un dispositivo di regolazione per autoveicoli con un microcalcolatore, il quale sulla base di segnali in entrata produce segnali digitali su di una uscita digitale, con un convertitore digitale/analogico, il quale trasforma i segnali digitali provenienti dall'uscita digitale del microcalcolatore in segnali analogici, e con un elemento di regolazione il quale è collegato con l'uscita analogica del convertitore digitale/analogico ed è collegato alla tensione positiva di bordo del veicolo, al fine di evitare che oscillazioni della tensione di bordo provochino oscillazioni non volute nella posizione dell'elemento di regolazione alimentato dalla tensione di bordo, il convertitore digitale/analogico è collegato con la tensione positiva di bordo, la quale è la tensione di riferimento del convertitore digitale/analogico.In the case of an adjustment device for motor vehicles with a microcomputer, which on the basis of incoming signals produces digital signals on a digital output, with a digital / analog converter, which transforms the digital signals coming from the digital output of the microcomputer in analog signals, and with a regulating element which is connected with the analog output of the digital / analog converter and is connected to the positive voltage of the vehicle, in order to avoid that oscillations of the on-board voltage cause unwanted oscillations in the position of the regulating element supplied by the on-board voltage, the digital / analog converter is connected with the positive on-board voltage, which is the reference voltage of the digital / analog converter.
