Abstract

A method for recording data from parameter values captured using sensors in a vehicle, particularly for the reconstruction of accidents, as well as a memory device and a device for recording such data, it being possible to record all relevant data continuously using low memory volume, and to save it permanently in a short period of time. For this purpose, the parameter values and/or data calculated from them are recorded at increasing time intervals for the instantaneous capturing point in time at decreasing density. A suitable storage device has a RAM (random access memory) for recording the data in each case over a certain time space and in a nonvolatile memory (such as EEPROM), to which the recorded data can be transmitted in parallel from the RAM within a few ms. An ASIC is suitable for its implementation.
