Method for monitoring sensors within a motor vehicle to ensure their correct operation using a system with a high degree of built-in redundancy to ensure that one device at each stage of a measurement chain is always working

摘要

Device for monitoring sensors within a motor vehicle with sensors combined in pairs (101a, 101b - 105a, 105b) to form sensor groups (101 -105). The sensors provide measurement values for corresponding physical values. Redundant signal provision means (108, 109) deliver signals to two redundant analysis devices (110, 111). The analysis devices compare the measurement signals from each measurement group to detect any faults. An Independent claim is made for a method for monitoring sensors in a motor vehicle.
