Method for operating a safety device

The present invention relates to a method for operating a

Safety device, wherein the safety device is part of a

Charging device for charging an energy storage of a vehicle is. State of the art

Electric vehicles usually have an electrical energy storage, such as a traction battery, which provides the electrical energy for the drive. If this electrical energy store is completely or partially discharged, then the electric vehicle has to control a charging station, at which the energy store can be recharged. So far, it is customary for this purpose that the electric vehicle is connected to the charging station by means of a cable connection at such a charging station. This connection must be made disadvantageously by a user usually manually. It is also necessary that charging station and electric vehicle correspond to each other

Have connection system.

Furthermore, occasionally wireless charging systems for electric vehicles are known. When inductive charging of electric vehicles, one or more coils (transmitting coils) are installed in or on the floor. Furthermore, one or more coils (receiving coil) are also arranged in the electric vehicle. If an electric vehicle is parked above the transmitter coil, it sends out an alternating magnetic field. The magnetic alternating field is absorbed by the receiving coil within the vehicle and converted into electrical energy. By means of this electrical energy can then by the contactless

Energy transfer a traction battery of the vehicle are loaded.

Furthermore, the energy storage of the electric vehicle can also be fed back be used. For this purpose, if necessary, a cable connection or an inductive power transmission can be used.

The publication DE102011010049 AI discloses such a system for charging a vehicle battery, in which the energy is transmitted inductively. A disadvantage of the prior art is that both wired and wireless charging method are used only to charge traction batteries of each vehicle. Some methods include additional functionalities, such as billing procedures, which charge the amount of charge delivered to the battery to the driver. Whether the vehicle was stolen and charged by the vehicle thief or loaded by the actual vehicle owner or an authorized driver does not matter in the prior art for charging. An authorized driver as well as an unauthorized driver can charge the vehicle at a charging station or at a power source, without being prevented. In addition, the authorities such as the police are not supported in the investigation of vehicle theft.

There is therefore a need for a method by which the theft of a vehicle can be made more difficult and / or more efficient.

Disclosure of the invention

The method according to the invention with the characterizing part of claim 1 has the advantages that vehicle theft is made more difficult and / or authorities such as the police are assisted in the investigation of vehicle theft.

According to the invention, a method for operating a safety device is provided, wherein the safety device is part of a charging device for

Charging an energy storage of a vehicle, preferably an electric or hybrid vehicle is. The security device is connected to an Internet-enabled server. In a first step of the procedure reads the Safety device the vehicle service data. In a second step of the method, the security device compares the vehicle service data via the server with a stolen database of reported vehicles.

Finally, the safety device sends a signal to the charging device when the vehicle is registered as stolen in the database. An advantage of this method is that car thieves of theft of vehicles is difficult. In addition, authorities (e.g., police) are involved in the investigation of

Vehicle theft supported. The measures mentioned in the dependent claims advantageous refinements of the method specified in the independent claim are possible.

Advantageously, the charging device is arranged in the vehicle. This is favorable in that each vehicle is independent of the

Ladeschnittpunkten the infrastructure (charging stations in the parking garage, the roadside, etc.) which carries in the charger built security device itself. The vehicle is thus on the charging device or the

Safety device itself able to check the status of the vehicle (stolen, not stolen) itself, without having to rely on, for example, that an external charging station is capable or not.

Furthermore, it is advantageous that the charging device is arranged in a charging station outside the vehicle. To arrange the charging device in an external charging station and not to install in the first place in each individual vehicle advantageously reduces the initial cost for the driver.

Advantageously, when the signal is received by the security device, the charging device does not start or interrupt the charging process of the energy store. If the safety device detects that the vehicle has been reported as stolen and is therefore listed in the stolen reported vehicle database, it will send an appropriate signal to

Loader. If the charging process has already started, this will advantageously interrupted. Is the energy storage of the vehicle

For example, only slightly charged, no further charge can be obtained, whereby the vehicle is clearly limited in its range and

for example, by the police can be found better. Alternatively, the charging process is not even started, so that the energy storage of the vehicle also remains empty, which in this case has a limited range result and allows more effective access of the police.

Advantageously, upon receipt of the signal by the security device, the charging device fictionally starts the charging process. The driver is informed that the energy store is being charged, ie the charging process is active without actually being charged (fictitious charging). If the driver thus waits for the completion of the charging process, the police have more time in case of notification of the location of the vehicle to get to the vehicle location and ensure the vehicle and possibly also arrest the thief of the vehicle.

Furthermore, it is advantageous that the charging device discharges the energy store upon receipt of the signal by the safety device. Instead of charging the energy store (e.g., a traction battery), the energy store is completely discharged. Thus, the vehicle is no longer able to leave the current location, allowing the police to find the vehicle better.

The charging device advantageously activates upon receipt of the signal by the

Safety device an immobilizer. Even if the energy storage is still sufficiently charged to put back a certain distance, the vehicle can not be moved due to the activated immobilizer.

Furthermore, it is advantageous that the charging device upon receipt of the signal by the security device, the location and the vehicle service data of the

Vehicle sends to the police. In the event that the vehicle is considered stolen, the police is thus informed, according to which vehicle (type, color, License plate, etc.) they must look for and where the vehicle is exactly. The location is advantageously transmitted in the form of GPS data.

Other features and advantages of the present invention will become

Expert from the following description of exemplary

Embodiments, which should not be construed as limiting the invention, with reference to the accompanying drawings.

Vehicle with a safety device according to an embodiment of the invention;

Fig. 3 is a schematic representation of a cross section through a

A vehicle having a safety device which is part of a charging device, which in turn is part of a charging station, according to a further embodiment of the invention;

The drawings shown in the figures are for reasons of

Clarity not necessarily drawn to scale. Like reference numerals generally designate like or equivalent components.

Figure 1 shows a schematic representation of the method for operating a safety device 10, which is part of a charging device 11, as they are For example, to charge an energy storage 12 (eg battery or

Traction battery) of a vehicle 13 (preferably an electric vehicle or hybrid vehicle) can be used. The security device 10 is connected to a server 14, which is advantageously connected to the Internet or can obtain information via the Internet. The security device 10 has access via the server 14 to a database 15 listing vehicles that are reported as stolen. Should the battery of the

Vehicle 13 are charged, the driver drives the vehicle 13 to a charging point. This can be wired or wirelessly (inductively) charged. Either the charging device 11 is located in the vehicle 13 or is part of a charging station 16. Regardless of the location of the charging device 11 (in the vehicle 13 or the charging station 16), the safety device 10 of the charging device 11 initially reads out the vehicle service data in a first step A. , These include, i.a. Vehicle type, vehicle color, license plate and the like. In a second step B, the security device 10 communicates with the server 14. In this case, the vehicle service data is compared with a database 15 in which stolen vehicles are listed. If it turns out that the vehicle 13 has been reported stolen or stolen, the security device 10 sends a signal to the charging device 11 in a third step C. The charging device 11 then initiates one, several or all of the following steps.

If the charging process of the traction battery 12 has already started and subsequently turns out that the vehicle 13 has been stolen, the charging device 11 interrupts the charging process. Alternatively, should the charging process not yet have been initiated, the traction battery will not be charged until the status of the vehicle 13 turns out to be stolen.

Further, the loader 11 may indicate to the driver, who is also likely to be the vehicle thief, that the charging process of the traction battery 12 has begun, although in fact is not being charged. It is thus charged only fictitiously by merely simulating a charging process. In order to fix the vehicle 13 permanently at the current location, the charging device 11 initiates the complete discharging of the vehicle battery 12. Without existing charge, the vehicle 13 can no longer be electrically moved. Because only fully electric operated vehicles 13 (so-called electric vehicles) thus can no longer drive, hybrid vehicles but due to the presence of an internal combustion engine are still ready to drive (even without battery charge), the charging device 11 activates the immobilizer 17. Thus, the vehicle 13 regardless of

Vehicle type (electric or hybrid vehicle) and state of charge of the battery 12 (partially charged or fully discharged) can not be moved. To the

Authorities such as To facilitate the police locating the vehicle and possibly even the arrest of the vehicle thief, the charging device 11 transmits the vehicle service data and the location of the vehicle 13 to the police. The location of the vehicle 13 is advantageously determined via GPS and transmitted in the form of GPS coordinates. In addition, further information such as date, time, etc. can also be transmitted. Furthermore, the loading device 11 continuously or repeatedly transmits the GPS coordinates to the police and / or suitable alternative authorities. If the driver is able to move the vehicle 13 nevertheless (failure of the immobilizer 15 or by means of the internal combustion engine), the police can thus locate and track the vehicle 13.

The vehicle 13 may be a pure electric vehicle, but may also be designed as a hybrid vehicle and have an internal combustion engine. The traction battery 12 may alternatively be charged by means of the charging device 11 by means of a wired or an inductive charging method.
