[0005] The invention is based on the object of providing a novel method for dynamic risk assessment for a specific parking space.

[0006] The object is achieved according to the invention by a method which has the features specified in claim 1.

[0007] Advantageous embodiments of the invention are the subject of the subclaims.

[0008] A method for dynamic risk determination for a specific parking space, wherein vehicles of a vehicle fleet are connected by data technology to a central computer unit external to the vehicle, in which a hazard database for risk determination is stored, provides according to the invention that the risk determination for the specific parking space is carried out dynamically and / or time-dependently on the basis of a current occupancy of neighboring parking spaces of the specific parking space, depending on real-time data of the vehicles of the vehicle fleet available in the hazard database.

[0009] By applying the procedure, a risk for a vehicle is determined, in particular with regard to a potential fire hazard from an electric vehicle, a hybrid vehicle or a fuel cell-powered vehicle.

[0010] In particular, the procedure reflects a protective wish of vehicle users to avoid close proximity to risk vehicles, for example in the form of relatively old electric vehicles, and / or certain parking spaces and / or clusters of other vehicles with certain drive systems, in order to thus reduce a potential fire hazard for the vehicle.

[0011] In one embodiment of the method, the drive type of the respective vehicle in the fleet and / or user-specific protection requirements related to the respective vehicle are transmitted to the computer unit so that these can be stored on the computer unit. The computer unit thus has information regarding the drive type and any existing protection requirements of a vehicle user, for example, that the vehicle should not be parked in an underground parking space with parked electric vehicles and / or outdated and unsafe charging stations.

[0012] For example, a fire risk hazard coefficient is determined for a specific parking space based on the occupancy of neighboring parking spaces. In particular, the drive types of other vehicles parked in the neighboring parking spaces are taken into account, as is whether the respective neighboring parking space has a charging station for charging an electrical energy storage device, particularly an electric vehicle. This hazard coefficient thus reflects whether a fire risk exists for a vehicle in the specific parking space.

[0013] In a further development of the method according to the invention, an individual danger coefficient is determined for each potentially considered parking space depending on the presence of a charging station for an electrical energy storage device; if a charging station is present, this is determined depending on the type and safety of the charging station and / or the charging capacity of the charging station and / or the age of the charging station and / or additionally implemented protective measures of the charging station and / or the potentially considered parking space. Such information for determining the individual danger coefficient for each potentially considered parking space can be made available to the central computer unit, for example, via an operator of a parking area, for example, an administration or a city administration, and in particular can be transmitted to the central computer unit.

[0014] According to the method according to the invention, all neighboring parking spaces within a specified radius of the specific parking space are identified, in particular to determine a potential fire risk for the specific parking space. Thus, the neighboring parking spaces within the specified radius of the specific parking space are taken into account in the risk assessment, so that a vehicle user is aware of a potential fire risk in the vicinity of the specific parking space and can then decide whether or not to use the specific parking space to park their vehicle, which can be a comparatively expensive vehicle.

[0015] This process identifies all other vehicles in neighboring parking spaces within the specified radius that may pose a fire hazard to the vehicle in the specific parking space. In particular, all electric vehicles and / or vehicles with a traction battery that may pose a potential fire risk to the vehicle in the specific parking space can be identified.

[0016] Furthermore, within the scope of the method according to the invention, for each additional vehicle identified that may pose a hazard, an individual static hazard coefficient is determined, at least depending on the type of electrical energy storage device of the additional vehicle and / or the age of the electrical energy storage device and / or the age of the additional vehicle. This means that for each additional vehicle that may pose a fire risk, in particular, an individual static hazard coefficient is determined, which can be taken into account in the risk assessment for the specific parking space.

[0017] In another possible embodiment, an individual dynamic risk coefficient is determined for each additional vehicle parked in a neighboring parking space, at least depending on the determined individual static risk coefficient and / or the risk coefficient of the potentially considered parking space and / or a distance between the specific parking space and the neighboring parking space. This means that essentially all parameters relevant to the risk assessment with regard to the specific parking space are taken into account in order to issue a corresponding recommendation to a vehicle user who is looking for a parking space that meets their individual safety requirements.

[0018] In one embodiment of the method according to the invention, an overall hazard coefficient for the specific parking space is determined based on the determined individual hazard coefficient of the parking spaces adjacent to the specific parking space. This overall hazard coefficient indicates, in particular, whether the specific parking space is suitable for parking the vehicle, taking into account the individual safety requirements that the vehicle user has for such a parking space.

[0019] In a further embodiment of the method according to the invention, the overall risk coefficient determined for the specific parking space is displayed in the vehicle of the vehicle fleet. The overall risk coefficient can be displayed in a corresponding color, for example, depending on the suitability for the vehicle. If the specific parking space is relatively unsuitable, the overall risk coefficient can be displayed as "red," whereas if the specific parking space is suitable for parking the vehicle, the overall risk coefficient can be displayed as "green" in the vehicle.

[0020] Embodiments of the invention are explained in more detail below with reference to a drawing.

[0021] The following shows: Fig. 1 schematically shows a block diagram for implementing a method for risk assessment for a specific parking space for a vehicle.

[0022] The single figure shows, by way of example, a block diagram for implementing a method for risk assessment for a specific parking space for vehicles 1 of a vehicle fleet, wherein all vehicles 1 of the vehicle fleet are connected for data purposes to a central computer unit 2 external to the vehicle. Furthermore, the central computer unit 2 is connected for data purposes to an operator 3 of a parking area, for example, an underground car park, and / or an administration, for example, a city administration, and / or a service provider for managing the parking area.

[0023] It is generally known that in recent years, there have been repeated cases of parked electric vehicles, hybrid vehicles, or fuel cell-powered vehicles 1 catching fire. The fire has often spread to other vehicles 1 located near the self-igniting vehicle 1 . Thus, there is a certain distrust of parked vehicles, especially electric vehicles. Some vehicle users are reluctant to park their vehicles 1 near electric vehicles, regardless of whether such fears can be statistically proven, i.e., whether they are justified, or not.

[0024] If a vehicle user owns a relatively expensive vehicle 1 or a vehicle 1 that is subjectively valuable to them, the vehicle user intends to minimize such a fire risk, particularly for their vehicle 1. This may mean that the vehicle 1 is not parked in an underground car park with parked electric vehicles and / or comparatively old charging stations L, for example, charging columns, or that the vehicle 1 is only parked there if a certain type of charging station L, particularly one with a comparatively high safety standard, is available in a parking environment.

[0025] There may also be temporal and spatial restrictions for a user of an electric vehicle to park his electric vehicle if the operator 3, for example a parking garage operator and / or an administration and / or a service provider, does not permit the parking of electric vehicles.

[0026] The following describes a method for risk assessment, in particular a fire risk, for a specific parking space. In particular, the method provides for the determination of an overall hazard coefficient G for the specific parking space, depending on the occupancy of neighboring parking spaces, particularly with regard to a potential fire hazard emanating from electric vehicles. In particular, the risk assessment for the specific parking space is carried out dynamically and / or time-dependently based on real-time data from the vehicles 1 of the vehicle fleet available in a hazard database of the central computer unit 2, based on the current occupancy of neighboring parking spaces of the specific parking space.

[0027] For example, a vehicle 1 of the vehicle fleet can combine its drive unit with an individual protection requirement S to avoid certain parking areas and clusters of vehicles 1 of a certain drive type A or to maintain a configurable distance from such vehicles 1 of the certain drive type A.

[0028] Vehicle 1 transmits its individual protection requirements S and its drive type A to the central computer unit 2, where these can be stored vehicle-specifically. In particular, the central computer unit 2 manages and processes the transmitted drive types A and individual protection requirements S of vehicles 1 in the fleet.

[0029] On the one hand, the aim is to provide a vehicle user with particularly precise information regarding the past, current, and / or future probability that, when using a specific parking space in a particular area, for example, electric vehicles are parked, will park in the future, or have parked there in the past. Such precise information can also be provided in controlled parking areas in the form of a guarantee, for example, from operator 3, if operator 3 ensures that a guaranteed condition is always maintained.

[0030] On the other hand, the use and driving in multi-storey car parks or certain parking spaces within multi-storey car parks, especially for electric vehicles, is regulated in such a way that an objectively given or subjectively perceived risk for vehicles 1 parked there of being affected by a band caused by an electric vehicle is reduced.

[0031] The procedure provides for the individual hazard coefficient to be determined in advance, for example once, for each potentially considered parking space in a parking area. In particular, the individual hazard coefficient is determined based on whether a charging station L, in particular a charging column, is available. If a charging station L is available, the type / design and safety of the charging station L are determined. Furthermore, the charging capacity of the charging station L is taken into account, in particular by determining whether it is a standard charging point with a comparatively low charging capacity or a rapid charging point with a comparatively high charging capacity.Furthermore, the age of the charging station L, additional protective measures implemented by the charging station L and / or the respective parking space potentially to be considered in relation to the charging station L, structural protection, for example in the form of a partition wall, etc., are used to determine the individual hazard coefficient. Information about the number of charging stations L and their respective properties is provided to the central computer unit 2 via the operator 3.

[0032] Next, all neighboring parking spaces, i.e. all parking spaces that are within a given radius of the specific parking space, are determined.

[0033] Subsequently, all vehicles 1 that are parked in the identified neighboring parking spaces and from which a hazard, in particular a fire hazard, may arise, for example all electric vehicles or all vehicles 1 with a traction battery, are identified.

[0034] Then, for each identified vehicle 1 that may pose a hazard, an individual static hazard coefficient is determined. In one possible implementation, this individual static hazard coefficient is not determined dynamically, but is permanently assigned to vehicle 1 and can, for example, also be determined using a database stored in the central computer unit 2.

[0035] In particular, the individual static hazard coefficient of the respective vehicle 1, which poses a hazard, for example, due to its drive type A, is determined based on specific parameters. In particular, the individual static hazard coefficient is determined depending on the type and age of an electrical energy storage device of the respective vehicle 1, the age of the vehicle 1, the protective measures implemented in the vehicle 1, in particular those that go beyond legal requirements, and / or statistical values ​​for this type of vehicle 1 and / or the electrical energy storage device for the respective vehicle 1.

[0036] Furthermore, for the respective vehicle 1 posing a hazard, for example, a fire risk, an individual dynamic hazard coefficient is determined, which is determined for a current situation, i.e., context-dependent. The respective individual dynamic hazard coefficient is determined depending on the determined individual static hazard coefficient of vehicle 1, the determined individual hazard coefficient of the specific parking space, for example, with regard to a charging process, in particular whether such a process is planned, and / or depending on the distance of a neighboring parking space, in which, for example, an electric vehicle is parked, from the specific parking space.

[0037] By means of the central computer unit 2, an overall hazard coefficient G is then determined for the specific parking space, in particular in a respective current parking position, in a respective current context, based on the individual dynamic hazard coefficient of the neighboring parking spaces of the specific parking space.

[0038] For example, the overall hazard coefficient G is determined by the individual dynamic hazard coefficients representing a probability of an undesirable event occurring at the specific parking space, and an overall probability of the non-occurrence of an undesirable event being formed by a product of a respective difference between 1 and the respective individual dynamic hazard coefficient of the neighboring parking spaces of the specific parking space.

[0039] In one possible embodiment, concerns and / or fears of vehicle users can be alleviated or even refuted through empirically collected data. This can be achieved by comparing and explaining fires recorded in the past involving electric and conventionally powered vehicles 1, for example in the form of a so-called "heat map." In particular, the "heat map" can be displayed in a vehicle user's vehicle 1 at their request, with particular reference to recorded fires in electric vehicles that have occurred in the past being visualized in a temporal and spatial manner. In one embodiment, additional information is displayed for each fire, for example the cause of the fire and its effects on the surrounding area. For comparison, recorded fires in conventionally powered vehicles 1 in the past can be displayed in a temporal and spatial manner.

[0040] Using a rule-based logic described above, which determines the overall hazard coefficient G of specific parking spaces, temporal-spatial areas are transmitted to the vehicle 1 requesting parking space, which are suitable for the vehicle 1 with its drive type A and its individual protection requirements S, i.e. are recommended, or should be avoided.

[0041] For example, an electric vehicle, designated as vehicle 1 in the vehicle fleet, is provided with temporal and spatial areas where a provider, in particular operator 3, prohibits parking or prescribes certain distances. For example, parking an electric vehicle in certain private garages may be prohibited.

[0042] In one possible embodiment of the method according to the invention, a comparatively very valuable vehicle 1, which does not necessarily have to have an internal combustion engine, is not recommended to park in parking spaces with certain types of charging stations L. For example, parking garages with more than 15 charging stations L are not recommended for parking the vehicle 1.

[0043] The determined actual or expected or assured total hazard coefficient G for a specific parking space is displayed to the vehicle user of vehicle 1 so that the vehicle user can decide whether or not to park his vehicle 1 in the specific parking space.

[0044] Vehicles 1 that could pose a danger or a relatively high danger can be allocated special parking spaces from which there is a lower danger to other vehicles 1.

[0045] With regard to the individual static hazard coefficient of a vehicle 1 and thus to the overall hazard coefficient G, a distinction can also be made between vehicle generations and / or vehicle systems depending on the drive type.

[0046] The rule-based logic for determining the overall hazard coefficient f icient G can also be applied to all hybrid vehicles.

[0047] Particularly for ship passages, journeys without electric vehicles in the cargo space are preferred, whereby this information is displayed in a vehicle 1 of the vehicle fleet, which applies the procedure described above, depending on the time and space.

[0048] In the case of tunnels, it may be provided that the vehicle user is offered a period with a minimum number of electric vehicles in the tunnel at the same time in order to exclude as far as possible a possible fire risk for himself and his vehicle 1.

[0049] In a further embodiment, it can be provided that the respective vehicle user in the vehicle 1 of the vehicle fleet is shown the respective costs that may arise if the vehicle 1 uses a later and possibly more costly ship transport, the vehicle 1 bypasses a tunnel, or the vehicle 1 parks further away from a destination of the vehicle user.

[0050] In particular, the vehicle user of the respective vehicle 1 of the vehicle fleet indicates how much more waiting time and / or how many more kilometers he is willing to drive, for example to avoid a tunnel.

[0051] Use of the method as a service offered for vehicles 1 of a vehicle fleet is monitored temporally and spatially, so that the vehicle user of a vehicle 1 of the vehicle fleet can essentially be continuously provided with current information, for example on the occupancy of certain parking spaces in a parking area.

[0052] The vehicles 1 of the vehicle fleet transmit to the central computer unit 2 a respective drive type A, a user-specific safety need, i.e. the individual protection requirements S, as well as a waiting time permissible for the respective vehicle user and an accepted detour or detour length.

[0053] The database of the central computer unit 2 stores current information on temporal and spatial restrictions for routes, parking areas, tunnels, ship passages, etc., whereby this information may also be available depending on a particular drive type A.

[0054] Furthermore, the central computer unit 2 checks rules stored depending on the drive type A of the respective vehicle 1 of the vehicle fleet, such as, for example, that the vehicle 1 should not be parked in an underground car park with more than 50 parking spaces.

[0055] As described above, the central computer unit 2 determines the individual dynamic hazard coefficient of the specific parking space with respect to the vehicle 1 and, depending thereon, locations suitable for the vehicle 1 are determined.

[0056] The central computer unit 2 then sends vehicle-specific temporal-spatial recommendations E to the vehicle 1, in particular to avoid certain locations, for example parking spaces, whereby areas and / or certain routes are also avoided taking into account the specific overall hazard coefficient G determined for the vehicle 1. The respective recommendation E also contains information on additional times, routes and / or costs that may arise for the vehicle 1, for example, by bypassing a tunnel.
