Method and system for determining parking spaces with charging stations based on vehicle data

The invention relates to a method for creating and operating

Occupancy maps of electric charging stations for vehicles and a system.

State of the art

Services in the area of cards and so-called human-machine interfaces are becoming increasingly important in the automotive industry. Such services may be based in particular on crowdsourcing.

The background to this is on the one hand the increasing equipment rate of vehicles by vehicle sensors and the increasing data-related connection to external units, on the other hand the demand or increasing market pressure for new value-added services for motorists.

For example, services in the field of community-based parking and mapping for highly automated driving (HAD) are currently known. These solutions basically work on the same principle. Over a

Vehicle sensors of different vehicles are collected data and sent to a server in a cloud. These vehicles act as so-called transmitter vehicles or as a transmitter. There will be the

aggregated and processed via algorithms and data mining methods to corresponding services. This

Services are then made available to other drivers via the cloud. The vehicles that use the services provided by the cloud are so-called receiver vehicles or receivers. However, the provision of features of an infrastructure can be problematic, which change frequently. Such features may be, in particular, parking lots with charging stations for vehicles, wherein the charging stations are provided unevenly by different operators and their number continuously increases or varies.

Disclosure of the invention

The object underlying the invention can be seen to propose a method and a system for flexible and operator-independent determination of electric charging stations.

This object is achieved by means of the subject matter of the independent claims. Advantageous embodiments of the invention are the subject of each dependent subclaims.

According to one aspect of the invention, a method for creating and operating occupancy maps of vehicle electric charging stations is provided. It is in one step of the procedure in an external

Server unit provided a parking card with parking for vehicles.

Subsequently, a charging process of at least one vehicle is detected at an electric charging station and determines a position of the at least one vehicle at a start of the charging process.

The determined position of the at least one vehicle during the charging process is transmitted via a communication unit of the vehicle to the external server unit.

It is the position of the at least one charging vehicle arranged as an electric charging station in the occupancy card or the

Parking card stored when the position of the at least one vehicle coincides with a parking possibility of the parking card. Through the process, a variety of data of the so-called

Broadcasting vehicles are used to find parking spaces with an electric charging station or charging stations.

In particular, the charging stations can be identified in a so-called on-street area. The identification of the locations of charging stations can be based solely on vehicle data. Since the method according to the invention is based on crowdsourcing, the position determination of the charging stations can be scalable as desired and can be carried out independently of charging infrastructure operators.

As a prerequisite, a functioning generation of a parking space map with information on public parking facilities can be used. Such a parking map can be created, for example, based on ultrasonic sensors, radar sensors or LIDAR sensors by a plurality of vehicles, which are coupled to a data-processing external server unit. The public parking facilities serve in particular a demarcation of private parking facilities, such as garage entrances. Alternatively or additionally, urban parking space maps and development plans for parking spaces can be used to carry out the method.

By the method according to the invention, the information of

Parking cards are enriched with appropriate meta-data to automatically get a map of electric charging stations and a document status of the electric charging station. The advantage here is that the method for determining the parking or parking with charging stations

based solely on vehicle data (crowdsourcing approach). As a result, a spatial situation of the charging stations can be determined independently of operators of the charging stations and constantly updated vehicle-based.

Preferably, the determination of positions and a loading process can be automated during a common use of electrically powered vehicles. In particular, this is not a data-leading

Communication of the charging station with the external server unit necessary.

Alternatively or additionally, the external server unit can obtain access to data of the charging station. In order to create an occupancy map of charging stations for vehicles, the at least one vehicle must be connectable to the external server unit in a data-conducting manner. In particular, access to vehicle data via a vehicle bus or at least relevant status information, such as, for example, an activated charging process and a position of the vehicle, the external server unit or a backend must be provided. For performing a differentiation regarding a parking space or a non-public one

Parking space, the external server unit has a corresponding updatable parking card.

The position of an electric charging station in the parking ticket or the

For example, occupancy map may be determined based on the following steps:

The at least one vehicle is parked enthralling. The state can be detected, for example via terminal 15 or deactivated ignition of the vehicle and transmitted together with a determined vehicle position to the external server unit.

In the external server unit, the transmitted position of the vehicle is compared with the parking space map.

If the vehicle position coincides with a parking possibility of the parking card and a charging of the vehicle has been detected, a registration of the charging station in the parking card or the

Occupancy card be performed by the external server unit.

The process can be confirmed and updated through the use of many vehicles. In particular, the method can be arbitrarily scalable and can also be used beyond city limits.

According to an exemplary embodiment of the method, the electric charging station is marked as occupied with the at least one vehicle arranged in the charging process in the occupancy card or the parking space card.

Especially if the charging station in the parking ticket or in the

Occupancy card is already known, one can to the charging station

connected vehicle together with a transmitted position of the vehicle in the external server unit to change the status of the respective charging station. At the beginning of a charging process, the charging station in the Occupancy card as "occupied", "not available" or as "currently loading".

According to another embodiment of the method is a

expected charging time of the at least one vehicle in the charging process via the communication unit to the external server unit.

As a result, additional information regarding the charging process can be transmitted to the external server unit. Based on the expected charging time, a timer can be activated in the external server unit.

As a result, a time can be determined for which other vehicles or a charging opportunity seeking vehicles at which the electric charging station can be expected to be available.

According to a further embodiment of the method, the at least one electric charging station is marked as available after expiry of the estimated charging time in the occupancy card or the parking space card. As a result, an occupancy card can be created, which the available

Automatoladestationen after a respective expected charging time of the vehicles automatically as available or at least as likely releases available. By activating the ignition of the at least one vehicle, a final release of the electric charging station can take place.

According to a further embodiment of the method a

Parking operation and a charging operation of the at least one vehicle detected by the at least one vehicle and as a status to the external

Transfer server unit for performing a comparison with the parking card. The information about the parking of the vehicle and the start of the charging process may preferably be in a bundled form as a

Status report, for example, as a data packet to be transmitted to the external server unit. The relevant information for creating and operating the occupancy card can thus be exchanged efficiently and quickly between the at least one vehicle and the external server unit.

According to a further exemplary embodiment of the method, at least one vehicle parked in the position of an electric charging station without being initiated by a charging operation from the external server unit is deemed to be a disorderly one parked vehicle marked. If a vehicle is parked in a parking space which has an electric charging station without initiating a charging process, it can be assumed that the parked vehicle is not an electrically operable vehicle and was therefore parked without authorization. It can thus be detected technically simple regulatory offenses.

According to a further exemplary embodiment of the method, the position of a vehicle parked in an irregular manner is transmitted to an administrative unit immediately or after a period of time has elapsed. For example, the administrative unit may be a parking lot management, which checks the vehicle and requests to release the electric charging station. Alternatively or additionally, the administrative unit may be a towing service, which is contacted directly or after a predefined period of time for removing the vehicle parked in an irregular manner. In particular, the process can be carried out automatically, whereby operating costs can be saved.

According to a further embodiment of the method, the position of the at least one electric charging station in the occupancy card or

Parking card confirmed by position data of at least one other vehicle. By this measure, so-called frequency method for confirming the determined charging stations can be performed. It can by the same vehicles at different times the same

Charging stations are registered and communicated to the external server unit. Thus, a robust method can be realized which can independently eliminate or correct errors in the detection of the charging stations.

According to a further embodiment of the method, a parking operation of the at least one vehicle is detected by switching off a vehicle ignition and transmitted to the external server unit. For example, it can be determined via a control unit or a voltage measuring device on a vehicle bus that the ignition of the vehicle is deactivated. As a result, it is technically easy to register a parking or parking of the at least one vehicle. According to a further aspect of the invention is a vehicle system, in particular for carrying out the method according to the invention

provided. The vehicle system has at least one electrically operable vehicle which can be charged to at least one electric charging station and has a communication unit. Furthermore, the vehicle system has at least one electric charging station, which is arranged in the region of a parking facility, and an external server unit for receiving data transmitted via the communication unit.

The method and the vehicle system can be used, for example, in the area of community-based parking. The provided occupancy cards can be used in particular by cities or municipalities.

The information of parking spaces at electric charging stations represents an immense added value for motorists in the search for a parking space. On the one hand for drivers of electric vehicles in search of a corresponding parking space, on the other hand as a parking space restriction or as a parking ban for motorists with combustion engine in search of parking. Such

Crowdscource-based solution can also ensure scaling, which in particular is independent of metadata of the respective

Elektroladestation or by charging infrastructure operators.
