Method for improving functional safety and increasing the availability of electronic closed loop control systems, and electronic closed loop control systems

摘要

A method for improving the functional security and increasing the availability of an electronic control system, particularly a motor vehicle control system, including hardware components and software components, wherein the hardware components are abstracted by at least one basis software component and/or a runtime environment, and in which an implemented security concept describes two or more software levels, wherein a first software level includes control functions of an application software and a second software level is designed as functional monitoring, for safeguarding against control function faults, wherein a data encryption, provided by at least one hardware component, and/or a data signature for securing the data of at least one communication channel of the hardware component is used with at least one first software component. The invention additionally describes an electronic control system for performing the method.
