The invention relates to a method for monitoring a component (), in particular a battery, of a motor vehicle having a first control unit () for monitoring the component () and a second control unit () for monitoring the component (), wherein the second control unit () is arranged at a distance from the first control unit () and communicates with the first control unit (), wherein the second control unit () is connected to the component () via a line (), in particular a hardware line, comprising the steps of transmitting operating data to the first control unit () by means of the second control unit (), checking the operating data in the first control unit (), transmitting data from the first control unit () to the second control unit (), switching off the component () by means of the second control unit () if interference is detected by means of the first control unit () and/or the second control unit (). The invention makes possible spatial separation of the control unit to be tested from the control unit carrying out the switching off, wherein the installation position of the control unit to be tested can be selected freely.

Method for monitoring a component in a motor vehicle

A method and a device are for predicting a life expectancy of a product, which includes at least two components. The life expectancy is ascertained as a function of an assumed field loading of the product. The components of the product are acted upon by different loadings and are operated, in each instance, at the different loadings until they fail. An end-of-life curve of the component is recorded on the basis of the load-dependent failure times of a component. An EOL curve of the product is ascertained such that at the different loadings, it includes the EOL curve of the components which has, in each instance, the shortest failure time at the corresponding loading. The anticipated service life of the product is determined as a functional value of the EOL curve of the product as a function of the predefined loading of the product.
