Description

  The present invention relates to a vehicle including a transponder according to the first stage of claim 1.

  An unpublished German patent application, application number 10004020573.6, describes a method for initiating a first vehicle safety measure. In this method, a first transceiver unit of a first vehicle radiates an electromagnetic field to a predetermined near region of the first vehicle. If there is a second transceiver unit of the second automobile in the predetermined vicinity region of the first automobile, the second transceiver unit receives a response signal received by the first transceiver unit of the first automobile. Send. When this response signal is received, safety measures are initiated for the first vehicle before the accident occurs. The response signal includes safety-related information regarding the second vehicle, in particular information regarding vehicle class, vehicle type, mass, vehicle weight, total vehicle weight, height, width, and / or travel speed. In order to initiate appropriate safety measures before an accident occurs, further data relating to safety during operation, in particular those that evaluate driving state variables, surrounding area data and / or driver behavior Taken into account. The transceiver unit is in the form of a transponder, and includes a receiving coil capable of inducing current with an electromagnetic field and a chip that is supplied with current and transmits a response signal.

  Patent Document 1 discloses a configuration for avoiding a collision between two automobiles or mitigating the influence of a collision when a radar device arranged in a first automobile is provided for scanning a surrounding area. is doing. Based on the information about the second car recorded by the radar device, the computer determines the probability of a collision between the two cars. If the probability of a collision is high enough, the computer sends a directed inquiry signal in the direction of the second car by means of a radar device. The second vehicle has a transponder for receiving the inquiry signal and transmitting a response signal that includes the dynamic and / or static characteristics of the second vehicle. The first vehicle computer uses the response signal to initiate corresponding safety measures for the first vehicle to avoid or mitigate the impact of the collision.

  Further, Patent Document 2 discloses a license plate including a built-in positioning unit (GPS) for confirming the current position of the vehicle. Items of location information relating to the current location of the vehicle (with the vehicle identifier attached) can be transmitted to the global communication system by means of a transmitter that can be activated. The transmitter can only be activated by a vehicle specific activation signal. The license plate also has an electrically readable identification tag that can be read or queried only after receiving the enable signal. Only the vehicle owner can send the enable signal. For this purpose, the owner of the vehicle has a corresponding code, which can be transmitted to the vehicle by means of a global communication system or a short range transmitter.

  The object of the present invention is to provide a vehicle comprising at least one transponder in which collision-related data is stored and can be technically realized at little expense. It is a further object of the present invention to provide a method for manufacturing a license plate for this type of vehicle.

  The object described at the outset is achieved by a vehicle comprising at least one transponder in which collision-related data are stored, having the features of claim 1.

  According to the invention, the transponder is arranged on the license plate of the vehicle. The transponder stores collision related data. Here, it is advantageous if the collision-related data can be read by scanning using electromagnetic waves in the radio frequency band. A technique called RFID (radio frequency identification) using electromagnetic waves (particularly, a radio frequency band) is a technique for identifying an object without contact. The RFID system has a transceiver unit and a transponder (also called an RFID transponder). When this system is used in road traffic, it means that the transceiver unit of the first vehicle can read the data stored in the transponder of the second vehicle. Each vehicle should be equipped with a transceiver unit and a transponder for wide application for security reasons and for optimal exchange of traffic-related data between various vehicles. The transponder has a microchip and an antenna. Passive transponders derive electrical energy from the electric field of the transceiver unit. In contrast, active transponders have their own power supply. As a result, the range can be greatly expanded. The RFID transponder is also called an RFID tag, and the word “tag” means an identification mark or a sign. The compact configuration of the license plate and transponder allows simple and practical implementation for large scale use. In this case, the design does not depend on the vehicle type. It can be seen that the transponder is a very cost effective component. The transponder is preferably a passive transponder, which further simplifies integration into the vehicle.

  It is advantageous if the crash-related data includes information on vehicle class, vehicle type, mass, vehicle weight, total vehicle weight, height, width, structural rigidity, standard deformation path, and / or deformation structure placement. is there. Furthermore, data relating to the owner of the vehicle can also be stored so that it can be read out by a suitable reader in the event of an accident. To enhance occupant protection, automobiles are equipped with more devices that operate in a more differentiated manner. This substantially applies to the deployment of the airbag system, the flexible operation of the belt pretensioner, and the use of switchable or adjusted absorber elements. With this kind of flexible component, it is very useful to know about specific safety related information about the expected collision partner for the collision, in order to protect the vehicle occupant and the predicted collision partner for the collision . If the anticipated collision partner for a collision has a large mass, for example, the safety device or protection device should be set as hard as possible. If the mass of the anticipated collision partner for the collision is relatively small, the safety device or protection device should react slowly so that the vehicle occupant and the expected collision partner for the collision can make optimal use of the deformation path . To that end, knowledge of the expected collision mass and / or other safety-related variables for the collision is very important. The transceiver unit of the first vehicle and the transceiver unit of the second vehicle can be incorporated in a series of manufacturing stages, or can be retrofitted separately or together to the vehicle as components of the safety device.

  The second described object is achieved by a method for manufacturing a license plate for a vehicle of this kind having the features of claim 6.

  According to the present invention, collision related data relating to vehicles is detected, assigned and stored in the transponder. The assignment and storage of vehicle-related data to owner-related data is likewise performed by the central management station. In this case, it is advantageous if the transponder is attached to the license plate by the central management station. For large-scale use, it is desirable for all vehicles on the road to be equipped with transponders, and all relevant operations are preferably carried out centrally and the central management office should be responsible. In particular, licensed offices are suitable for this role. Thus, when the vehicle is used for the first time, the vehicle is always equipped with a transponder.

  Further advantageous refinements of the invention are described in the dependent claims.

  The present invention will be described in more detail with reference to an exemplary embodiment of a schematic plan view showing an accident scenario involving two vehicles.

  The figure shows a first vehicle 1 and a second vehicle 2 in a traffic scenario that leads to a frontal collision if an accident occurs. The traveling directions of the two vehicles 1 and 2 are indicated by arrows 3 and 4.

  In this exemplary embodiment, the two vehicles 1, 2 are provided with transponders 5, 6 respectively. The transponder can be read by scanning using an electromagnetic wave in a radio frequency band. The transponder stores collision-related data regarding the vehicles 1 and 2. In this refinement, the transponders 5, 6 are also called RFID transponders. The transponders 5 and 6 are arranged on the license plates 7 and 8 of the vehicles 1 and 2. The radio frequency band includes a radar frequency band. Since the license plates 7 and 8 of the vehicle are often dirty, optical scanning is not particularly advantageous and not very suitable.

  A first transceiver unit 9 arranged in the front area of the first car 1 scans the transponder 6 of the second car 2 in order to obtain collision-related data about the second vehicle 2. On the other hand, the second transceiver unit 10 arranged in the front region of the second automobile 2 uses the transponder 5 of the first automobile 1 in order to obtain collision-related data relating to the first vehicle 1. Scan. Collision-related data can also be transmitted wirelessly as an encoded code or unencoded information. In a simplified exemplary embodiment (details not shown), only one of the two vehicles 1, 2 comprises a transponder 5, 6.

  The minimum detection distance and scanning speed of the transponder should be able to ensure that information is reliably provided at relative speeds up to 220 km / h. In order to be able to adjust the appropriate actuator system in a timely manner before the start of the collision, the provision of information should end approximately 100 ms before the start of the collision.

  As a function according to the detected collision-related data, the control units 13 and 14 for the respective automobiles 1 and 2 can start the appropriate safety measure means 11 and 12 before an actual accident occurs. As the safety measure means 11, 12, for example, a corresponding actuator system may be provided with a restraining system and / or an actuator adjusting means corresponding to the vehicle structure in order to improve the protection of the occupant and / or the collision partner against the collision. it can.

  The collision related data includes the vehicle class, vehicle type, mass, vehicle weight, total vehicle weight, height, width, structural rigidity, standard deformation path, and / or arrangement of the deformation structure of each vehicle 1 and 2. Information can be included. The response signal of each transponder 5, 6 including safety-related information can also have the following further functions. First, the response signal transmits safety-related information from one vehicle 1, 2 to the other vehicle 1, 2. Secondly, the response signal can be used directly as a trigger for initiating the appropriate safeguard means 11, 12, as described in German patent application No. 102004020573.6. . Thereby, the severity of the accident and / or the seriousness of the accident can be reduced. In a further simplified refinement of the invention (details not shown), the transmission of safety-related information by means of response signals can be dispensed with. In this refinement, the response signal only serves as a trigger for initiating the appropriate safety measures 11, 12 for each vehicle 1,2.

  In order to initiate appropriate safety measures 11, 12 before the actual accident occurs, further data relating to safety during operation of the vehicles 1, 2 (especially driving state variables, surrounding area data, and / or The evaluation of the actions of the drivers of the vehicles 1 and 2 that are approaching can be taken into account as an addition.

  The transponders 5, 6 can in particular be passive transponders 5, 6. In this refinement, the transponders 5, 6 are provided with a receiving coil (not shown in detail) that can induce a current in the electromagnetic field of the transceiver units 9, 10 of the vehicles 1, 2 that are approaching, And a chip for transmitting a response signal including information related to safety. Since it is not necessary to establish an electrical connection with the in-vehicle electronic system, the improved form of the transponders 5, 6 can be realized with little cost.

  The license plates 7, 8 can be arranged in the rear and / or front area of the cars 1,2.

  In the method of manufacturing the license plates 7 and 8 for the vehicles 1 and 2, the central management station detects, assigns, and stores the collision-related data regarding the vehicles 1 and 2 in the transponders 5 and 6. The assignment of the vehicle related data to the owner related data and the storage of the vehicle related data are similarly performed by the central management station. The attachment of the transponders 5, 6 to the license plates 7, 8 can be carried out by a central management office, in particular an authorized office. For a wide range of applications of the transponders 5, 6, a centralized manufacturing method is necessary. The central management station must reliably hold vehicle-specific data for a wide variety of vehicle types in order to store appropriate collision-related data in each transponder 5, 6 with a clear assignment.

  For security reasons (protection against tampering), it is advantageous if the transponders 5 and 6 cannot be removed without breaking.

  The manufacturing method of the vehicles 1 and 2 according to the present invention and the license plates 7 and 8 for the vehicles 1 and 2 according to the present invention reliably provides and assigns collision-related data, and in terms of hardware costs. The production of license plates 7, 8 suitable for optimized large-scale use is reliably processed. It is particularly suitable to be used in combination with various distance control evaluation techniques (eg radar, video and / or rider) to further enhance vehicle occupant safety.

It is a schematic top view which shows the scenario of the accident where two vehicles were caught.
