The present invention relates to a system for detecting safety-critical
measured quantities, in particular yaw rates or acceleration data in
automotive vehicles, comprising at least two independent measuring
channels with sensors that are independent of one another and elements
for verifying a malfunction or a failure of the measuring channels. The
first measuring channel and the additional measuring channel(s) are
operated in hot redundancy employing sensors of the similar type but not
exactly identical in such a manner that the sensors are operated in
parallel and without restriction. This invention also relates to a device
consisting of a sealed housing with a plug, and the aforementioned system
is accommodated in the sealed housing.
