Abstract
A device for short-distance recording for motor vehicles is disclosed for the evaluation of an accident or near-accident driving situation. A storage arrangement is provided in which speed measurements are simultaneously written into at least two parallel storage branches. A plurality of time-limited storage areas are defined in each storage branch. Each storage area has a storage portion which can be operated as a ring storage and a storage portion arranged subsequent to the latter which can be operated as a linear storage. The speed values, which are written into the ring storage in a continuous manner during the course of normal driving, are permanently stored in one storage branch when the criterion v equal to 0 km/hr occurs, and in the other storage branch when the criterion a greater than a deceleration threshold value occurs. Subsequent speed values are written into the linear storage of the respective storage area until the set time limit, after which a free storage area of the respective storage branch is switched to.
