Abstract
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.
