With reference to FIGS. 1 through 5, a concept for preparing collision protection devices or pre-crash systems in the event of looming intersection accidents with the aid of Cloud-based collision data according to exemplary embodiments of the present invention will be described in the following text in the form of a summary and in other words.
To begin with, features are discussed that crashed vehicle 120, collision-endangered vehicle 220, crashed other vehicle 110 and collision-relevant other vehicle 210 may possess. For example, “Cloud computing” means that a part of the IT landscape, in this connection especially the hardware such as the computing center, data memory as well as the software of administration device 100, is no longer operated on its own on the user side or provided at the local level, but is leased as a service from one or more provider(s), which generally is/are located at a remote geographical location. Applications and data are then no longer stored on a local computer but in the “cloud”. For example, the position data are acquired and supplied in the form of GPS coordinates, via a navigation system, smartphone or the like. A data exchange between administration device 100 or the Cloud server and supply device 130 or control device 230 is accomplished by means of a data link via a navigation system, a smartphone or the like, for example. Also, in particular a so-called eCall system or an assistance system for sending electronic messages following an accident is provided on the vehicle side. Optionally, for example, a driver assistance system such as a so-called intersection assistant having front sensors and/or side sensors is provided on the vehicle side, which, for example, monitors lateral traffic at intersections with the aid of radar technology. Furthermore, pre-crash systems or at least one collision protection device 221, for instance, are provided in the vehicle. The pre-crash systems and the at least one collision protection device 221 are, for example, irreversible and reversible crash structures, airbags or also actuators which are activated in the event of collisions in order to protect occupants and/or pedestrians. It is also provided, in particular, that pre-crash systems or collision protection devices 221 are able to be activated or ignited [at] the instant of a collision for increased protection.
If an intersection accident occurs in which, for example, two vehicles such as vehicle 120 and other vehicle 110 crash at an intersection or a road junction, then the following collision characteristics, for instance, are compiled using sensor data: the speed of vehicle 120; the deceleration of vehicle 120 before and/or after the collision; the angle and/or position in the intersection prior to/following the collision or the angular change or offset of vehicle 120; information from passive safety sensors or acceleration sensors, pressure sensors and the like with respect to the location where an impact on the own vehicle or vehicle 120 took place, at which angle the impact on vehicle 120 took place, at which speed the impact on vehicle 120 occurred, etc. The collision characteristics are linked with position data or GPS coordinates, similar to the way it is done in an e-Call system, and transmitted via a data interface or transceiver device 133 to administration device 100 or a Cloud server. In administration device 100, the data are linked with information regarding the weather, road condition such as construction work, and the temperature and/or the like, for example.
Via a number or sum of collisions or accidents at a particular position, e.g., in a certain region such as an intersection or road junction, a Cloud-based database with the aforementioned information is generated per collision in administration device 100. This creates a database in connection with accidents at at least one geographical position. Each compiled parameter, for example, is weighted with probabilities, especially a collision data set or a combination of the parameters per collision. This produces a Cloud-based accident data statistic in administration device 100.
An intersection assistant in vehicle 220 detects a danger of an imminent collision and a speed of other vehicle 210 in the approach of other vehicle 210, for instance laterally in relation to vehicle 220. The intersection assistant is able to issue a warning to occupants of vehicle 220. However, according to exemplary embodiments of the present invention, a linkage with the collision data sets or the Cloud-based accident data statistics, and a measurement of the sensor system of the intersection assistant may take place as well. In this way, a probable impact and a severity of the impact are able to be predicted in a Cloud-based manner via a multitude of data or statistics. Depending on the Cloud-based collision data sets, available pre-crash systems or collision protection devices 221 are able to preadjust the, in all likelihood, most optimal protective measures or to optimally adjust them to the imminent collision with a very high probability, such as with regard to the angle, speed, decelerations, etc.
The method thereby improves the pre-crash measures of vehicles using at least one of the aforementioned features. Vehicles without intersection assistant, but equipped with collision protection device 221 may access the collision data sets in administration device 100 also in a preventive manner and, for example, preadjust collision protection device 221 when encountering especially dangerous road sections, even if no immediate danger is detected. It is furthermore possible, for example, to make the Cloud-based accident data available to governments or traffic authorities so that constructive optimizations or improvements can be undertaken.
The exemplary embodiments described and shown in the figures have been selected merely as examples. Different exemplary embodiments are combinable with one another, either completely or with regard to individual features. An exemplary embodiment may also be supplemented by features from another exemplary embodiment. Furthermore, method steps may be carried out repeatedly and also performed in a sequence other than the one described.
