Abstract
A method and a system for data protection of fixed and learned control data of duplicated, program-controlled computers, in which the control parameters are stored in an EEPROM. The memory available in the EEPROM is divided into three areas. Each area is monitored using a check sum (check sum , check sum , check sum ) that is stored therein. Only the self-learned variables are maintained redundantly. Thus, the ability to store more data than previously in the EEPROM with the same data protection and the same accessibility is provided, thus allowing more flexible solutions with respect to varying customer requirements to be offered.
