摘要:
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.
摘要:
For the acquisition and evaluation of safety-critical measured quantities, for example, of yaw rates (GR) as an input quantity of an automotive vehicle control system, the measured quantities are produced by way of two measuring channels (M1, M2) which are independent of each other. One measuring channel (M1) covers the entire measuring range, and the other measuring channel (M2) is set to a partial measuring range. To identify errors, the output quantities of the measuring channels (M1, M2) are checked for correlation with the measured quantities acquired by the measuring channels and/or for plausibility of the measurement results.
