METHOD FOR IMPROVING THE FUNCTIONAL SECURITY AND INCREASING THE AVAILABIILTY OF AN ELECTRONIC CONTROL SYSTEM, AND ELECTRONIC CONTROL SYSTEM

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.

1. A method for improving the functional safety and increasing the availability of an electronic closed-loop control system, for a motor vehicle control system, comprising hardware components and software components, wherein the hardware components are abstracted by at least one basic software component and/or at least one runtime environment and in which an implemented safety concept describes two or more software levels, wherein a first software level comprises control functions of a piece of application software and a second software level is in the form of a function monitor for the purpose of protecting against errors in the control functions, wherein data encryption and/or data signature, provided by at least one hardware component, is used for data protection for at least one communication channel of the hardware component with at least one software component.
