DE3520383A1 - Crash indicator - Google Patents

Abstract

It is known that in the case of multiple crashes insurance companies charge the costs equally to all participants in each case because of a lack of accident reconstructions. Moreover, it is not possible to determine the vehicle drivers who maintain speeds and distances as laid down in regulations. The crash indicator described in the invention provides a possibility here of indicating at which point the first collision occurred. At the same time, it is also possible for the speed last held before the first crash to be indicated and stored. The previously known speed recorders and acceleration pick-ups do not permit this information. An expanded crash indicator, or one supplemented in accordance with the subclaims, counts overshoots of freely adjustable retardation or acceleration values. Overshoots indicate the nature of the driving with respect to the retardation and acceleration behaviour of the vehicle drivers. It is possible to aim at a substantially kinder use of hired vehicles or official vehicles, buses etc. The gentle way of driving results in fuel saving. Furthermore, there is the prospect that an expanded crash indicator will be confirmed as leading to a gentle way of driving where there is an urge, for sporting performance as well. The number of signal triggerings arising from desired overshootings of acceleration or retardation is directly connected to fuel consumption. Thus, minimising signals automatically yields the ...

Description

Tasks:

The invention is based on the object of holding on to pile-ups or to prove which vehicle hit another first is. It also allows the desired, adjustable deceleration or acceleration to be exceeded to count and to prove this and the direction of impact in the case of individual collisions.

In addition, the speed values of your own vehicle deliver to the Time of the collision (collision speed) important data for reconstruction of the accident process. After a collision there is a time-adjustable Signal, which any other control or regulation processes such as "loosen belt, doors open, give attention or help signals, etc. "can trigger.

Description: The invention relates to a deceleration or acceleration display device. An extension of the device is possible according to the sub-terms. The sub-terms themselves are also part of the invention. The end value blocking allows the Information or proof of the location in the vehicle where a first Shock occurred.

It is known that in serial accidents of vehicles the individual Vehicles are so damaged that evidence of the first point of the collision (e.g. at the front or rear of the vehicle) is not possible. The crash indicator announces the storage of the first exceeded adjustable acceleration or deceleration value the direction of the first impact. According to dependent claim 2, the crash indicator allows at the same time to save the digital speed shortly before a collision and prove. According to dependent claim 3 is the assessment of the driving character (gentle or jerky acceleration or deceleration) by vehicle drivers accordingly of the counted signals possible.

Claims (3)

Claims: 1. Crash indicator for deceleration or acceleration detection with final value blocking, especially for vehicles of all types, characterized in that that with decelerations or accelerations by the effect of the inertial force a mass part (predominantly ball or pendulum) is shifted and when exceeded of adjustable acceleration or deceleration values in a final or verification position is blocked, which also indicates the direction of the shock. 2. Expandable crash indicator characterized in that digital Speed values before a first collision are retained when through the final value blocking according to claim 1 a signal was triggered. The triggered Signal also allows other control processes or regulation processes. 3. Crash indicator according to claim 1 and 2, characterized in that in any other adjustable position of acceleration or deceleration values a countable and / or storable signal occurs when the end value blocking is still active was not reached.
