SENSOR ARRANGEMENT, PARTICULARLY FOR A PASSENGER PROTECTION SYSTEM OF A MOTOR VEHICLE

摘要

The invention relates to a sensor arrangement, particularly for a passenger protection system of a motor vehicle, comprising  a first group of sensors (10, 12) by means of which a first group of state parameters jointly usable by a decision-making unit connected downstream for detecting a first event can be detected,  a first digital unit (20) coupled on the input side to at least one sensor (12) of the first sensor group, processing the sensor output signals fed thereto and providing the same for forwarding to the decision-making unit as digital values, wherein - a second group of sensors (14, 16, 18), by means of which a second group of state parameters jointly usable by the decision-making unit connected downstream for detecting a second event can be detected, - a second digital unit coupled on the input side to at least one sensor (16, 18) of the second sensor group, processing the sensor output signals fed thereto and providing the same for forwarding to the decision-making unit as digital values, wherein - at least one sensor (10) of the first sensor group is coupled to the second digital unit (22) and at least one sensor (14) of the second sensor group is coupled to the first digital unit (20), and - the digital units (20, 22) are coupled on the output side to a first and a second node (28, 30) combining the digital values fed to each to corresponding first and second output lines (32, 34), such that the first node (28) combines the digital values corresponding to the sensors (10, 12) of the first sensor group to the first output line (32), and the second node (30) combines the digital values corresponding to the sensors (14, 16, 18) of the second sensor group to the second output line (34).
