Definitions

  • the present invention relates to a method for preparing a refueling.
  • the present invention also relates to a corresponding device, a corresponding computer program and a corresponding storage medium.
  • US2013139897A1 provides a system and method for safely filling hydrogen using real-time hydrogen tank expansion data.
  • the system includes an expansion measurement unit, an on-vehicle control unit, a service station-side control unit, and a wireless communication unit.
  • the expansion measuring unit is arranged on a hydrogen tank of the vehicle and measures the degree of expansion of the hydrogen tank and generates an output signal accordingly.
  • the on-board control unit converts the output signal into a wireless output signal.
  • the forecourt control unit stops hydrogen refilling by a hydrogen filling device when the wireless output signal indicates an unsafe level of tank expansion.
  • the wireless communication unit is provided to carry out wireless data communication between the vehicle-side control unit and the gas station-side control unit.
  • US2020276909A1, US10800281B2 and US2020346554A1 describe further communication systems and methods for hydrogen refueling and charging of electric vehicles.
  • the method proposed in US20130091042A1 and the security system based on it provides security based on geographic location with different levels of access and allows the user to select entities to be protected, geographic locations, geographic boundaries, permissions and access levels for specific geographic locations and geographic boundaries, and security alerts to configure. They make decisions to grant, deny, or assign a specific level of access based on the user's current geographic location and their own configuration for that geographic location or boundary, and send out security alerts.
  • US2018213376A1 and US9355561B2 disclose methods for so-called V2X communication.
  • the invention provides a method for preparing a refueling, a corresponding device, a corresponding computer program and a corresponding machine-readable storage medium according to the independent claims.
  • the approach according to the invention is based on the knowledge that the accelerated refueling of hydrogen gas, for example, should take into account the thermodynamics of the refueling process and should therefore regulate the process in a closed manner.
  • the maximum temperature, minimum and maximum pressure specified for the tank container must not be exceeded or fallen short of at any time.
  • a conventional unidirectional infrared connection from the vehicle to the fuel pump is severely impaired by scratches on the transmitting or receiving optics and by ice formation around the fuel nozzle or nozzle and is therefore affected by failures in practice, which makes accelerated refueling impossible.
  • the connection does not provide for a return channel from the fuel pump to the vehicle, so that the supported fueling processes cannot be called up and therefore no agreement can be reached on a process that is optimal for the given combination of vehicle and fuel pump.
  • the proposed method also takes into account the fact that metallic contacts, which are essential for wired communication, should be avoided when refueling with hydrogen, especially in the vicinity of the tank coupling, because any sparks here could ignite the hydrogen gas explosively.
  • Wireless (radio-based) communication is therefore preferable to wired communication to protect the filling station from explosions.
  • radio due to the unimpeded propagation of the radio waves, the use of radio involves special challenges that are overcome according to the invention.
  • a triggering event is required to activate the overall process.
  • the radio link must transmit data so reliably that the functional and general safety of the refueling can be guaranteed.
  • third parties who are within radio range of the vehicle or fuel pump should not be able to interfere with or manipulate the process, for example through jamming or overload attacks (denial of service, DoS).
  • DoS denial of service
  • the participants assigned to each other in this way must also exchange the parameters relevant to refueling, such as the number of tank containers in the vehicle and their filling level, internal tank temperature and maximum permitted refueling pressure as well as the maximum possible flow rate from the fuel pump or the gas temperature. Both partners can make suggestions for the refueling process - such as the maximum refueling time and speed - submit and independently take measurements of, for example, the ambient temperature.
  • the radio connection must be information and operationally secure before refueling.
  • the procedure described below achieves this goal regardless of the radio technology, filling station infrastructure and hardware used, as well as the participant responsible for comparing the filling parameters. It is also independent of the technology used for location determination and can be used for refueling any fuel (gaseous or liquid) as well as charging electric vehicles.
  • a basic idea of the proposed solution is to use a mathematical ordering function and an optional model to make a functionally reliable decision, either via all parameters individually or in combination, which of the parameter values should be used to plan or regulate the refueling process.
  • the method according to the invention allows the necessary comparison of parameters of both refueling partners or across multiple tank containers of a vehicle.
  • it uses a large variety of radio technology that is available on the market and that is usually already provided in petrol stations or - in particular semi-automated - vehicles, which can thus be reused within the framework of the process without any significant additional design effort, without the refueling process due to unnecessarily conservative parameter specifications for all vehicles -or.
  • the vehicle and the fuel pump mutually authenticate and authorize each other for the fueling process. This in turn enables automated refueling processes and billing. In this way, it can also be ensured that the vehicle and fuel pump are compatible with each other because they meet the functional safety requirements set by both parties and verified by communication.
  • FIG. 1 shows the preparation and initialization phase of a refueling according to a first embodiment.
  • FIG. 2 shows a schematic diagram of a control unit according to a second embodiment.
  • a refueling scenario at a gas station where a fuel cell vehicle is to be refueled with gaseous hydrogen, for example, is considered as an example.
  • the procedure is applicable to all types of fuel (gas, liquid, cryogenic, etc.) as well as applicable to electric vehicle charging.
  • a conventional, partially automated or autonomous refueling vehicle drives to the vehicle to be refueled and refuels it.
  • the method can be combined with any other method of IT security or functional safety.
  • characteristics of security features for example the values for pressure and temperature in the tank container, are transmitted via radio technology before, during or after the refueling process. It is conceivable that at least part of this data transmission will have to meet increased requirements for IT security and functional safety.
  • FIG. 1 shows the method (10) according to the invention for preparing such a refueling.
  • the start of communication is triggered on both sides--at the gas station and at the vehicle--by coincident or different events (11, 12).
  • the removal (11) of the fuel nozzle from its holder, the vehicle driving over a contact or the triggering of a light barrier, on the part of the vehicle, for example, a command input or the opening (12) of the fuel filler cap come into consideration.
  • the fuel pump and the vehicle preferably after activating an immobilizer (13)—perform a leak test (14) of their own system independently of one another. If the test (14) is passed, the method (10) is continued by releasing (15) a tank valve for refueling. Both systems are then coupled (16) to one another in order to establish an information-secure (17) and operationally reliable (18) connection.
  • This information can include querying a database, which managed locally by one of the partners or by a remote server via an Internet connection via mobile communications, Ethernet or similar.
  • the fuel pump and vehicle negotiate a relevant data transmission protocol for the user data of the refueling process and determine the - possibly standardized - thermodynamic refueling protocol (20) and its parameters (21). For the purposes of the following explanations, it is assumed that the fuel pump is responsible for managing the procedure (10) and thus making the final decision on the combination of the parameters.
  • the aim of this specification (21) is that parameters of the same type (usually physical variables relevant to the course of the fueling process) with different values from the vehicle or fuel pump are combined into one value. The result of this is then used for planning (22) the refueling process or for carrying it out, together with other types of parameter values that are also combined or collected only from one of the partners.
  • Direct input values for the planning process (22) such as ambient temperature, maximum permissible filling pressure, fuel volume flow and pressure or its rate of change within the limits specified by the respective participant, maximum permissible refueling duration or volume and minimum required volume flow come into consideration. Values derived from this, such as an index or values of a fixed table entry, for example a standardized refueling protocol, which are partly selected independently of one another by each partner on the basis of direct input values, should also be considered, as well as the selection of a predefined fallback plan, according to which refueling can continue to function reliably can be used if communication fails.
  • Parameters to be considered during filling include, for example, the temperatures of the environment and the fuel in the tank hose, as well as its flow rate, pressure and rate of pressure change.
  • Such a specification (21) can also be expedient in order to bring together a parameter from a large number of similar parameters of different tank containers of a tank system of the vehicle, such as their respective maximum permissible refueling pressure, temperature, refueling quantity or current filling level.
  • definition (21) is as follows:
  • a combined value is then defined for each type of parameter according to a specified method via the parameter group—for example by selecting a value from the set of received values, for example their median, minimum or maximum—or a scalar function of the received values. Their geometric or arithmetic mean value comes into consideration.
  • the "most conservative" parameter value i.e. the one with the lowest risk potential for functional safety, for example the minimum from the quantity of the maximum permissible gas pressures transmitted for the respective tank containers.
  • the result is used for planning (22) the refueling process.
  • value set a (false) subset of several values
  • steps are repeatedly applied: a) Forming the value set as a combination of parameters from different partners.
  • the selection of a value set of common origin (partner or tank container) is particularly expedient; it is also useful to use all possible combinations of parameters and their origin one after the other as a set of values.
  • the parameters are set (21) to this result and used for further planning (22) of the refueling process.
  • This method (10) can be implemented, for example, in software or hardware or in a mixed form of software and hardware, for example in a control unit (30), as the schematic illustration in FIG. 2 illustrates.
