Registration arrangement for motor vehicles with a measured value presentation suitable for evaluating accidents
First Claim
1. A device for short-distance recording in a motor vehicle, which comprises:
- a processing means, wherein said processing means controls the operation of said device;
a means for measuring speed; and
a storage arrangement for electronically storing the measured speed values in such a way that they enable an immediate evaluation of one of an accident and a near-accident driving situation by one of displaying and printing,wherein said storage arrangement is provided with at least two independent storage branches, wherein each of said storage branches has a plurality of storage areas, andwherein each of said storage areas has a first storage portion which can be is operated as a ring storage and a second storage portion which is operated as a linear storage, and further wherein at least one of the measured speed values is written into said storage branches simultaneously in a cycle required for a desired resolution, and further wherein a ring storage is exited and a further storage is effected in the subsequently arranged linear storage in a first of said two storage branches when said vehicle is stopped and in a second of said two storage branches when fixed deceleration values, which are caused by one of braking and impact, are exceeded.

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.
