Sensor Arrangement, Particularly for a Passenger Protection System of a Motor Vehicle
First Claim
1. A sensor arrangement, particularly for a passenger protection system of a motor vehicle, comprising,a first group of sensors by means of which a first group of state parameters jointly usable by a first decision-making unit connected downstream of the first group of sensors for detecting a first event, having a first digital unit (20) coupled on an input side thereof to at least a first sensor (12) of the first group of sensors, which processes sensor output signals fed thereto and provides digital values to be forwarded to the first decision-making unita second group of sensors (14,16, 18) by means of which a second group of state parameters jointly usable by a second decision-making unit connected downstream of the second group of sensors for detecting a second event, a second digital unit (22) coupled on an input side thereof to at least a first sensor (16, 18) of the second group of sensors, which processes sensor output signals fed thereto and provides digital values to be forwarded to the second decision-making unit, wherein at least a second sensor (10) of the first sensor group is coupled to the second digital unit (22) and at least a second sensor (14) of the second sensor group is coupled to the first digital unit (20), andthe first and second digital units (20, 22) are coupled on output sides thereof to a first and a second node (28, 30) combining the digital values respectively fed into a first and a second output line (32, 34) such that the first node (28) combines the digital values corresponding to the first and second sensor (10, 12) of the first sensor group on the first output line (32) and the second node (30) combines the digital values corresponding to the first and second sensors (14, 16, 18) of the second sensor group on the second output line (34).

Abstract
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 first 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. The arrangement processes the sensor output signals fed thereto and providing the same for forwarding to the first decision making unit as digital values. A second group of sensors (14, 16, 18), by means of which a second group of state parameters jointly useable by a second decision making unit is connected downstream for detecting a second event can be detected with a second digital unit coupled on the input side to at least one sensor (16, 18) of the second sensor group. The arrangement processes the sensor output signals fed thereto and providing the same for forwarding to the second 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 second digital unit (22) and at least one sensor (14) of the second sensor group is coupled to the first digital unit (20). The digital units (20, 22) are coupled on their output sides to a first and a second node (28, 30) combining the digital values.
