Definitions
- the present invention relates to a method for accident detection in a vehicle.
- the present invention also relates to a corresponding device, a corresponding computer program and a corresponding storage medium.
- a permanently installed measuring device sends an electrical impulse to various further control devices, which in turn can activate various occupant protection systems, via the bus of the respective vehicle during a considerable vibration.
- these include airbags, belt force limiters, belt tensioners and roll bars on the vehicle. Crash sensors of simple design only recognize this
- Vehicle deceleration is exceeded, while more advanced gauges are able to detect the impact severity in the form of a crash index or crash severity index.
- the prior art also includes permanently installed or retrofittable telematics units (Connectivity Control Unit, CCU) for motor vehicles, which include such sensors and automatically, for example, to a
- CCU Connectivity Control Unit
- DE2001138764 proposes an arrangement for detecting a frontal collision in a vehicle in which
- Plausibility sensor at least one front sensor is used, the one
- the front sensor is an acceleration sensor from which both the
- Acceleration signal as well as the derived speed signal for plausibility is examined.
- the results of this study are ORed to produce a plausibility signal.
- it is provided to store the plausibility signal for a predetermined time in the control unit. This is of particular interest in the event of destruction of the front sensor for increased safety.
- the invention provides a method for accident detection in a vehicle, a corresponding telematics unit or other device
- FIG. 1 shows the flowchart of a method according to a first
- FIG. 2 shows a telematics unit according to a second embodiment in a vehicle.
- FIG. 1 illustrates the basic sequence of a method according to the invention
- Procedure (10) A vehicle owner or mechanic collects the
- Identification number of a particular vehicle (process 11), based on which a model name is determined (process 12).
- the model can also directly by simple, z. B. to a vehicle registration information to be selected without departing from the scope of the invention.
- the crash-relevant features to be considered in one embodiment may include, for example, a vehicle type (sedan, sports car, SUV, truck, etc.) and a weight class (eg, up to 1000 kg, 1000 to 1500 kg, 1500 to 2000 kg, and over 2000 kg Empty weight).
- a model name could be assigned to the type "sports car” and a mass between 1000 and 1500 kg.
- Another application parameter is the installation location of the acceleration sensor or the telematics unit (21) containing it, as indicated in FIG.
- This installation location can either be measured or graphically assigned in an upstream step and has a direct influence on the
- the acceleration is cyclically measured in the unit (21) (process 16).
- the real vehicle accelerations at the center of gravity (22) of the vehicle (20) are determined on the basis of the measured accelerations and the particular installation position
- This method (10) can be implemented, for example, in software or hardware or in a mixed form of software and hardware, for example in the telematics unit (21).
Abstract
Procédé (10) pour la détection d'un accident dans un véhicule, caractérisé par ce qui suit : - identification des caractéristiques du véhicules entrant en jeu dans les collisions (13); - mesure d'une accélération par un accéléromètre du véhicule (16); - détermination, au moyen de l'accélération et des caractéristiques, d'un indice de sévérité de collision (19).
