Title: Method for storing and retrieving data in a control system, in particular in a motor vehicle

Abstract: The method is used to store and retrieve data in a control system, in particular in a motor vehicle, which contains a computer, a RAM memory and a flash memory. When the control system is switched off, operational data of different types, which can change while the control system is operating and which are required again after the control system is switched on again and which are stored in the RAM memory, are then stored in the flash memory. The flash memory is managed by means of a circular buffer method and can hold multiple copies of the operational data of the same type. When the control system is switched on, the most recent operational data of a respective type of data are determined and output to the RAM memory.
