Electronic Control System for a Safety Device of a Motor Vehicle
First Claim
1. An electronic control system for a safety device of a motor vehicle equipped with a computer that receives sensor signals and outputs a triggering signal for the safety device, the electronic control system comprising:
- a printed circuit board having a defined geometry;
first and second motion sensors arranged on the printed circuit board, the first and second motion sensors having at least one of an identical construction and identical operating effect; and
wherein the first and second motion sensors are arranged at an approximately identical location on the printed circuit board in order to provide respective output signals, in a proper operating mode, having opposite signs but identical amounts over an entire operating range, whereby one output signal provides a plausibility check for the other output signal.

Abstract
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.
