Problems solved by technology

There are load situations or event scenarios in which although a collision with an obstacle occurs, the damage that occurs does not result in injury to the occupants and triggering of the restraint means is therefore unnecessary.

Embodiment Construction

[0074] exist figure 1 The vehicle 1 is shown schematically in a top view. exist figure 2 The vehicle 1 is shown in a side view. The same technical features are designated with the same reference numerals in all figures. A coordinate system 2 is associated with the vehicle, the x-direction of which is oriented horizontally, coincides with the center axis of the vehicle 1 and points in the forward travel direction. The y-direction, like the x-direction, is directed from the center of the vehicle toward the left half of the vehicle. The z-axis points vertically upwards. The vehicle 1 has a device 10 for early accident detection. The device 10 for early detection of an accident comprises a large number of sensor modules 20 which are installed at different positions in the vehicle, here in the front part 3 of the vehicle 1 . These sensor modules each include an acceleration sensor 21 . The sensor module 20 is associated with the evaluation device 30 in terms of information ...

Abstract

The invention relates to the early detection of accidents in the context of vehicles. A method for identifying the occurrence of an accident in advance is proposed, comprising the steps of: obtaining local accelerations at different distributed positions in a vehicle (1) by means of acceleration sensors (21) installed at different positions; The resulting accelerations determine local shock information for the different locations; the shock information for the different locations is evaluated together and the accident information is derived and the accident information is output. The method is implemented using a device (10), which includes: a large number of acceleration sensors (21) installed at differently distributed installation locations in the vehicle (1) for obtaining local accelerations at corresponding installation locations; one or more a processing circuit (22) for respectively determining local impact information for different installation positions by means of the respectively measured local accelerations, and for jointly evaluating the impact information for different installation positions and deriving accident information and outputting An evaluation device (30) for accident information.

Description

technical field [0001] The present invention relates to early detection of accidents in the context of vehicles. This early detection of the accident is particularly necessary so that, in the event of an accident, active safety systems such as, for example, airbags, seat belt tensioners or the like can be optimally activated. Background technique [0002] Systems are known from the prior art which evaluate the time course of the speed reduction with the aid of acceleration sensors and thereby attempt to differentiate between different accident scenarios (which are also referred to as load situations) in order to determine the necessary conditions for triggering airbags and / or seat belt tensioning the best time for a computer or other security system. For example, DE 101 41 886 A1 describes a system of this type in which, in order to determine the triggering time for a restraint device (Rückhaltemittel, sometimes also called a retention device) in the vehicle, two speed redu...
