Load analysis method for use in electromechanical system of e.g. motor vehicle, involves determining characteristic value using system specific load parameters and loading time for detecting loading grade of system component

摘要

The method involves acquiring system specific load parameters (x1-x4) of a component in an electrical and/or electromechanical system, and determining a characteristic value (K) by using the load parameters. The value is found by taking into consideration a loading time (T). A loading grade (B) of one component of the system is determined using the value by a control device, where the device includes a computing unit. The load parameters include system force, temperature, current, voltage and/or speed of the component. An independent claim is also included for an apparatus for load analysis in electrical and/or an electromechanical system.
