Definitions
- the invention relates to a method for coordinating an evaporation process of a motor vehicle having a hydrogen tank by means of an assistance system according to the preamble of patent claim 1.
- the invention also relates to an assistance system.
- DE 102014226873 A1 relates to a device and a method for indicating the safety of a hydrogen tank when a vehicle fire occurs.
- the device includes a hydrogen storage tank, and a thermal pressure release device stored in a valve of the hydrogen storage tank. Additionally, a controller is configured to sense a flow rate of hydrogen discharged from the hydrogen storage tank using a sensor to determine whether the sensed flow rate of discharged hydrogen is within a predetermined reference flow rate range. The controller is also configured to transmit a warning signal when the sensed flow rate of dispensed hydrogen is included within the predetermined flow rate range.
- the object of the present invention is to create a method and an assistance system by means of which the safety of a motor vehicle and the area surrounding the motor vehicle can be increased.
- One aspect of the invention relates to a method for coordinating an evaporation process of a motor vehicle having a hydrogen tank by means of an assistance system, in which, depending on a hydrogen pressure in the hydrogen tank, the evaporation process of hydrogen in an area surrounding the motor vehicle is initiated by means of an electronic computing device of the assistance system.
- a communication device of the assistance system receives evaporation information relating to another motor vehicle having an additional hydrogen tank and the evaporation process of the hydrogen tank of the motor vehicle is coordinated as a function of the evaporation information from the other motor vehicle.
- a method is thus presented as to how the motor vehicle can be coordinated with the hydrogen tank with regard to evaporation in order to minimize the risk of ignition.
- the safety of motor vehicles with a hydrogen tank, which could produce dangerous ignition mixtures due to uncoordinated evaporation, can thus be increased.
- the risk is minimized and a method can be implemented to inform everyone in the area and the owners about this risk.
- the motor vehicle makes contact with the other motor vehicle in the vicinity, in particular using a non-wired technology, for example vehicle-to-vehicle (V2V) communication or vehicle-to-infrastructure (V2X) communication.
- the motor vehicles communicate via the communication device and send the exhaust information and possibly also data regarding route planning from a fleet management system to the motor vehicle further. This can be carried out from motor vehicle to motor vehicle as well as coordinated, for example, via a central electronic computing device, which can be a backend server, for example.
- the points in time are selected in such a way that the time between the evaporation is maximized. If the evaporation is too close together, for example, the owners of the vehicles can be informed about the danger via backend communication and display options on the vehicle can be used to warn bystanders or the fire brigade can be informed. This can be used in a similar way to a so-called eCall.
- the evaporation information is transmitted by means of near-field communication between the motor vehicle and the other motor vehicle.
- the motor vehicle can communicate directly with the other motor vehicle via vehicle-to-vehicle communication (V2V communication; vehicle-to-vehicle communication).
- V2V communication vehicle-to-vehicle communication
- the other motor vehicle sends the evaporation information to the latter via vehicle-to-infrastructure (V2X communication; vehicle-to-infrastructure communication), with the infrastructure then also transmitting the evaporation information to the motor vehicle via V2X communication.
- V2X communication vehicle-to-infrastructure communication
- the communication between the motor vehicle and the other motor vehicle can thus be carried out in different ways. As a result, the evaporation information can be reliably transmitted to the motor vehicle.
- an evaporation time and/or a quantity of hydrogen and/or the position of the other motor vehicle and/or a pressure in the other hydrogen tank and/or a location of an evaporation valve on the other hydrogen tank is transmitted as evaporation information.
- the motor vehicles can thus communicate with one another via the communication device and send information about their location, the pressure in the hydrogen tank, the amount of hydrogen charged, the expected evaporation time and the location of the drain valve in the motor vehicle and, if necessary, data about their route planning from a fleet management system. It can thus be reliably decided whether a Evaporation of the hydrogen tank of the motor vehicle can be carried out without exceeding the 4 percent concentration in the air, for example.
- an evaporation quantity of hydrogen in the hydrogen tank and/or an evaporation time of the hydrogen in the hydrogen tank are coordinated.
- the amount of hydrogen emitted can be adjusted accordingly.
- the evaporation time can also be coordinated. If, for example, the other motor vehicle has already emitted hydrogen, the evaporation time can be shifted as far as possible, so that the evaporation time of the motor vehicle is carried out later in order to prevent a critical amount of hydrogen in the air mixture.
- the evaporation process is additionally coordinated as a function of a hydrogen content in the area surrounding the motor vehicle.
- the motor vehicle itself or the environment in which the motor vehicle is located can have a corresponding measuring device for measuring the hydrogen content in the environment. If, for example, the critical hydrogen content, for example 4 percent in the ambient air, has already been reached, the evaporation process can be delayed accordingly. This can prevent a critical concentration of hydrogen in the air mixture.
- an environmental model of the environment is created by means of the electronic computing device as a function of information about the evaporation of the motor vehicle and as a function of the information about the evaporation of the other motor vehicle.
- the environment model includes the evaporation information of all motor vehicles with hydrogen tanks in the area.
- an approximated mixing model can be carried out based on the location, in particular this should be an open field or a narrow street in order to calculate the volatilization.
- the calculation or determination of the environment model can either be carried out decentrally on all motor vehicles or centrally on a motor vehicle or on a backend.
- the corresponding environment model can be created in detail for different environments, whereby an excessive hydrogen content in the environment can be prevented.
- a warning device of the assistance system is activated and a warning for the surroundings is generated by means of the warning device.
- devices inside the motor vehicle can be used for this purpose, for example, in order to carry out a warning of the surroundings.
- a horn of the motor vehicle or a light device of the motor vehicle can be actuated.
- microphones can be switched on, for example, which warn the environment, in particular people in the environment, that, for example, a critical value of the hydrogen content in the air can be found. This can be implemented, for example, via a voice message sent out via the microphone.
- the warning device is designed centrally, and for example in a forced vaporization process, which means that the vaporization must be carried out forcibly, for example because the pressure in the hydrogen tank is too high, although the critical value at If hydrogen is already present in the air mixture, the environment can be warned, for example, and the fire brigade, for example, can already be notified that a critical value is present here.
- the method is in particular a computer-implemented method.
- a further aspect of the invention relates to a computer program product with program code means which, when they are processed by an electronic computing device, cause this to carry out a method according to the preceding aspect. Therefore, the invention also relates to a computer-readable storage medium with a computer program product.
- Yet another aspect of the invention relates to an assistance system for coordinating an evaporation process of a motor vehicle having a hydrogen tank, with at least one electronic computing device and with a communication device, the assistance system for carrying out a Method is formed according to the preceding aspect. In particular, the method is carried out using the assistance system.
- the electronic arithmetic unit is designed outside the vehicle and this electronic arithmetic unit receives the evaporation information and an evaporation information of the motor vehicle centrally and, depending on this, the electronic arithmetic unit creates an environment model for the environment.
- the electronic computing device is designed to generate a control signal for a venting device of the surroundings for venting as a function of the environment model created.
- the corresponding values and/or the environment model and corresponding warning message can be transmitted to the infrastructure, for example a measured value display for an underground car park, a home automation system, or a control or monitoring center, which then, for example, triggers ventilation systems, for example, in particular to reduce the gas concentration of hydrogen, can be carried out.
- the infrastructure for example a measured value display for an underground car park, a home automation system, or a control or monitoring center
- Advantageous configurations of the method are also to be regarded as advantageous configurations of the assistance system.
- the assistance system has specific features which enable the method to be carried out or, in an advantageous embodiment, enable the method to be carried out.
- Fig. 1 is a schematic plan view of an embodiment of a
- Fig. 2 shows a schematic flow chart according to an embodiment of the
- FIG. 1 shows a schematic side view of an embodiment of an assistance system 10.
- the assistance system 10 is shown in particular in a parking garage 12.
- a motor vehicle 14 as well as another motor vehicle 16 and yet another motor vehicle 26 are located in the multi-storey car park 12.
- the motor vehicle 14 has a hydrogen tank 18 with an evaporation valve 20.
- the additional motor vehicle 16 also has an additional hydrogen tank 22 with an additional evaporation valve 24 .
- the yet further motor vehicle 26 has yet another further hydrogen tank 28 .
- the assistance system 10 is designed to coordinate an evaporation process 30 of the motor vehicle 14 having the hydrogen tank 18 .
- the assistance system 10 has at least one electronic computing device 32, which in the present case can be embodied as a central electronic computing device external to the motor vehicle. Furthermore, the assistance system 10 has at least one communication device 34 , which is embodied in the motor vehicle 14 in the present case. In the present case, the further motor vehicle 16 also has a further communication device 36 . The still further motor vehicle 28 has a still further communication device 38 .
- the vaporization process 30 of hydrogen into an environment 40, in this case in particular the multi-storey car park 12, of the motor vehicle 14 is initiated by means of the electronic computing device 32 of the assistance system 10 as a function of a hydrogen pressure in the hydrogen tank 18.
- FIG. 1 shows that the additional motor vehicle 16 and the yet additional motor vehicle 26 transmit the evaporation information 42 to the central electronic computing device 32 .
- the further motor vehicle 16 and the yet further motor vehicle 26 transmit the evaporation information 42 directly to the motor vehicle 14, for example via vehicle-to-vehicle communication.
- the communication takes place by means of near-field communication between the motor vehicle 14 and the other motor vehicle 16 .
- an evaporation time and/or a quantity of hydrogen and/or a position of the additional motor vehicle 16 and/or a pressure in the additional hydrogen tank 22 and/or a location of the evaporation valve 24 on the additional hydrogen tank 32 can be transmitted as the evaporation information 42.
- an evaporation quantity of hydrogen in the hydrogen tank 18 and/or an evaporation time of the hydrogen in the hydrogen tank 18 can be coordinated.
- the hydrogen sensor 44 is designed outside the vehicle. It may also be that the hydrogen sensor 44 is provided inside the motor vehicle, ie in the motor vehicle 14 .
- an environment model 46 is created by means of the electronic computing device 32 as a function of the evaporation information 42 of the motor vehicle 14 and as a function of the evaporation information 42 of the other motor vehicle 16 .
- a warning device 48 of the assistance system 10, presently located inside the motor vehicle 14, is activated and by means of the Warning device 48 a warning for the environment 40 is generated.
- the warning device 48 can also be provided by the environment 40, for example the multi-storey car park 12 in the present case.
- the invention thus proposes that, for example, by means of motor vehicle-to-infrastructure communication, a coordinated temporal and/or spatial distribution of the evaporation processes 30 or the evaporation quantities is realized with the aim of achieving the lowest possible maximum concentration and/or falling below limit values within the environment 40 .
- the measured values and/or the warning messages can be forwarded to the infrastructure, for example the multi-storey car park 12 .
- the measured value display for underground garages, home automation system, control and monitoring center can be forwarded, in which case, for example, the venting device 50 can be activated to reduce the gas concentration.
- it can be realized, for example, that underground car parks are released for the use of motor vehicles with a hydrogen tank.
- step S1 motor vehicle 14 is parked or in motion, being stationary for a very long time, for example being in a traffic jam.
- step S2 the motor vehicle 14 establishes direct communication with the other motor vehicle 16 or, via the electronic computing device 32 external to the motor vehicle, with the other motor vehicles 16, 26 in the area 40.
- step S3 the data relating to the evaporation process 30 are exchanged. For this purpose, in particular the location, pressure of the hydrogen storage device, charged amount of hydrogen, probable evaporation time, the location of the evaporation valve 20 on the motor vehicle 14, the route planning and the emission quantity are communicated.
- a fourth step S4 environment model 46 of motor vehicles 14, 16, 26 is created.
- the environment model 46 of the motor vehicles 14, 16, 26 is created, with an approximate mixture model also being calculated here in particular on the basis of the location. For this the environmental conditions, such as the open field or narrow streets, can also be taken into account.
- the corresponding data from the motor vehicles 14, 16, 26 in the relevant environment 40 is entered into the volatilization calculation.
- the evaporation times are coordinated as a function of the environment model 46 determined for the motor vehicles 14, 16, 26, with the evaporation processes 30 being able to be determined and assigned accordingly.
- step S8 if the evaporation is too close together in time, the owners of the motor vehicles 14, 16, 26 can be informed about the danger via backend communication; display options on the motor vehicles 14, 16, 26 can be used to warn bystanders and the fire brigade, for example, can also be informed.
- This method can be used similar to a so-called eCall.
- the environment model 46 can be determined both decentrally on all motor vehicles 14, 16, 26 or centrally, as shown here, in the central electronic computing device 32 external to the motor vehicle.
