An electronic control system for a safety device of a motor vehicle includes a first sensor for a motion quantity, a computer for converting the motion quantity to a triggering signal for the safety device, and a second sensor for checking the plausibility of the sensor signal supplied by the first sensor. The two sensors are arranged with an identical construction and/or effect and at an at least approximately identical location on a printed circuit board such that, in a proper operating mode, their output signals have different preceding signs and are identical with respect to their amount over their entire operating range.

Electronic control system for a safety device of a motor vehicle

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 for detecting a first event can be detected, a first digital unit () coupled on the input side to at least one sensor () 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 (), 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 () 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 () of the first sensor group is coupled to the second digital unit () and at least one sensor () of the second sensor group is coupled to the second digital unit () and at least one sensor () of the second sensor group is coupled to the first digital unit (). The digital units () are coupled on their output sides to a first and a second node () combining the digital values.
