Definitions
- Vehicle systems in accident situations to make comprehensible For this purpose, relevant data from a period of a few seconds before the accident are recorded in accident situations and near-accident situations, such as when an airbag is triggered or when emergency braking is triggered. These data are designed to objectify accidents to individual accident parties and to assist in understanding the course of the accident and understanding its circumstances.
- data recorders are usually at a trigger, d. H. when a trigger event occurs, only data stored in a period prior to the triggering event.
- a data recording can end with the triggering of a restraint system. Such a fixed end of data storage may result in the loss of important information after the triggering event.
- a triggering events for example, a change of an operating mode of a respective system, such as.
- FIG. 1 shows a flow chart which is oriented along a time axis 1.
- an automated driving function of a system such as a vehicle
- a triggering event occurs by a request to a driver to control the vehicle by taking manual control.
- another triggering event such as activation of a restraint system of the vehicle, occurs, as indicated by symbol 5.
- data recording of data of the vehicle ends with the deactivation of the automatic
- the data in a time range 9a which extends from a first time before time t1 to a second time after time t1, can be transferred into the read-only memory and evaluated accordingly later.
- the data lying after the time t1 are detected after the time t1, written into the volatile memory and then, for example, after expiration of the time range 9a, written to the read-only memory.

Abstract
La présente invention concerne un procédé pour stocker des données d'un système en fonction de la situation. Selon ce procédé, des données du système sont acquises, regroupées dans au moins un bloc de données (9, 9a) et stockées dans une mémoire volatile. En réaction à la survenue d'au moins un événement de déclenchement (5) prédéfini, les données regroupées dans le ou les blocs de données sont transférées de la mémoire volatile à une mémoire morte. Une fenêtre temporelle dans laquelle les données relatives audit ou auxdits blocs de données sont acquises est sélectionnée de manière automatique et dynamique en fonction du ou des événements de déclenchement (5).
