Vehicle information registrator

Abstract

 The present invention belongs to the class of electronic devices for registration of vehicle information, by closed circuit, in a memory unit protected from destructive factors such as mechanical and thermo impacts, in the case of accident or catastrophe of the vehicle. The device is aimed to be a technical mean of reconstruction of the crash dynamics, in the case of accidents or catastrophes, similar to the "black box" used in aviation, and provides the following functions:

• capturing, processing and registration, in internal memory, of the information coming from sensors and from equipment of the vehicle;
• registration, in internal memory, of information coming from incorporated accelerometer (overcharges and impacts on three spatial axes);
• protection of the internal memory from mechanical and thermo impacts and conservation of the deposited information, in the case of accident or catastrophe of the vehicle;
• reading of the information using a notebook and unequivocal reconstruction with graphic representation by mean of a PC simulator which permits the visualization of all the movements of the vehicle before and during the accident;
• technical state diagnostics of the vehicle at the moment of the accident or catastrophe;
• registration of geographic position of the vehicle and of astronomic time of the accident.

Description

[0001] The present invention regards a device of registration, by closed circuit, of vehicle information on a memory device protected of various destructive factors, using as a technical mean of reconstruction of the dynamics of heavy incidents or catastrophes, similar as the functions of "black box" in aeronautics.

[0002] The aim of the present invention is to realize a device, new and original, aimed to execute the following functions:

• capturing, processing and registration, in internal memory, of the information coming from sensors and from equipment of the vehicle;
• registration, in internal memory, of information coming from incorporated accelerometer (overcharges and impacts on three spatial axes);
• protection from mechanical and thermo impacts and conservation of the deposited information, in the case of incident or catastrophe of the vehicle;
• reading of the information using a notebook and unequivocal reconstruction with graphic representation by mean of a PC simulator which permits the visualization of all the movements of the vehicle before and during the accident;
• technical state diagnostics of the vehide at the moment of the accident or catastrophe;
• registration of geographic position of the vehicle and of astronomic time of the accident.

[0003] The above listed innovations are obtained from the invention in subject as described in the claims.

[0004] The invention is exposed, in sequel, in detail with aid of the annexed Fig. 1 which illustrates a possible structure of realization, among the numerous other realizations based on the same principle.

[0005] The device presents a box with relative connectors which contains the following elements:

• data processing module for the data come from sensors and from the equipment of the vehicle 1,
• data control and codification module 2,
• protected module of the data registration 3,
• positioning data processing module 4,
• module of accelerometers 5,
• the second power supply source 6.

[0006] Evidently the invention can be developed by mean of numerous modifications of the practical-applicative nature anyway, without exit from the environment of the invention claimed here below.
