ELECTRONIC CIRCUIT ARRANGEMENT FOR CONNECTING AT LEAST ONE ACTIVE ROTATIONAL SPEED SENSOR, ESPECIALLY IN UTILITY VEHICLES

摘要

The invention relates to an electronic circuit arrangement for connecting at least one active rotational speed sensor (1) of a vehicle to a control unit (6), by means of an associated signal conditioning circuit (4), for further processing of the rotational speed signal. A normally closed switching element (3) is added to the electric circuit for the power supply of the active rotational speed sensor (1), and can be switched into the open state by means for identifying an overload in the sensor line (A) or (B), in order to prevent an overload that would damage the active rotational speed sensor (1).
