Definitions
- the present invention relates to a method for operating a system with a parking lot, which comprises several parking areas, and with a motor vehicle, wherein stationary induction charging devices of the parking areas interact with mobile induction charging devices of the motor vehicles for wireless energy transmission.
- the invention further relates to such a system.
- a stationary induction charging device For wireless energy transmission with a motor vehicle, a stationary induction charging device is usually used, which interacts with a mobile induction charging device of the motor vehicle.
- an energy coil of one of the induction charging devices is used as a primary coil and an energy coil of the other induction charging device is used as a secondary coil.
- the primary coil generates an alternating magnetic field, which induces a voltage in the secondary coil.
- the primary coil and the secondary coil and thus the energy coils of the induction charging devices must be positioned accordingly relative to one another.
- a parking lot usually includes several parking spaces. It is conceivable to each provide the parking areas with a stationary induction charging device, so that the respective parking area can interact with the mobile induction charging device of a motor vehicle for energy transmission.
- the stationary induction charging device of the respective parking area and the associated mobile induction charging device of a motor vehicle parked on the parking area must be positioned relative to one another in order to enable energy transfer and increase the efficiency.
- the positioning can be done by a motor vehicle driving into the parking area by the driver or at least partially autonomously.
- this has the disadvantage that there is no reliable and/or precise positioning of the induction charging devices relative to one another, so that energy is not transferred or is transferred with reduced efficiency. It is therefore desirable to carry out the positioning of the motor vehicle on the parking area and thus the positioning of the induction charging devices relative to one another in a targeted manner. For this purpose, it is conceivable that the parking area and the motor vehicle communicate with one another.
- the DE 102017 202 966 A1 describes a system with a parking space and at least one motor vehicle.
- the parking areas of the car park are equipped with occupancy sensors.
- the motor vehicle is informed about the occupancy status of the respective parking area.
- the present invention is concerned with the task of providing improved or at least different embodiments for a method for operating a system with a parking space and at least one motor vehicle of the type mentioned above and for such a system, which in particular eliminate disadvantages from the prior art.
- the present invention is concerned with the task of providing improved or at least alternative embodiments for the method and the system, which are characterized by reliable and more precise positioning of motor vehicles in parking areas and increased efficiency of wireless energy transmission.
- the present invention is therefore based on the general idea of providing parking areas of the parking lot with stationary induction charging devices in a system comprising a parking space and at least one motor vehicle, which, during operation, provide a directed field for aligning a motor vehicle relative to the associated parking area and thus relative to the stationary one Generate induction charging device, wherein at least two of the adjacent mobile induction charging devices generate the field with different frequencies, and wherein the motor vehicle receives the fields and detects the local intensity and thus signal strength as well as the frequency.
- the motor vehicle when approaching a parking area, the motor vehicle can clearly see which parking area and thus which stationary induction charging device is used for wireless, inductive energy transmission with a mobile induction charging device of the motor vehicle due to the closer arrangement to the parking area being approached due to the higher intensity and the frequency associated with the higher intensity should, so that reliable navigation of the motor vehicle to the parking area approached as well as optimal alignment and positioning of the induction charging devices to one another can take place.
- motor vehicles are positioned reliably and precisely on parking areas of the parking lot, which at the same time results in improved energy transfer between the induction charging devices and thus increased efficiency.
- the method in particular a corresponding computer program product, automatically recognizes which is the strongest received signal and thus the highest local intensity and can distinguish this from the neighboring parking areas based on the different frequency and position it correctly.
- the method for operating the system with the parking lot and at least one motor vehicle is used.
- the parking lot has at least four parking areas, preferably several parking areas.
- the respective parking area is provided with a stationary induction charging device, which interacts with a mobile induction charging device of a motor vehicle for inductive wireless energy transmission.
- the respective one Parking area can be driven in one direction, which is also referred to below as parking direction.
- At least two of the parking areas, preferably the respective parking area are arranged in a row running parallel to the parking direction, the row also being referred to below as a longitudinal row.
- At least two of the parking areas are arranged in a row running transversely to the parking direction, the row also being referred to below as a transverse row.
- the respective stationary induction charging device To align the mobile induction charging device with the stationary induction charging device, the respective stationary induction charging device generates a field directed in the parking direction, which is also referred to below as the alignment field.
- the property of the alignment field directed in the parking direction means that the field lines of the alignment field run more in the parking direction and less transversely to the parking direction. The respective alignment field is therefore stronger along the associated longitudinal row than along the associated transverse row.
- the induction charging devices of the parking areas of at least one of the transverse rows generate the alignment field alternately with a first frequency and a second frequency, which are also referred to below as the first alignment frequency and the second alignment frequency.
- the respective motor vehicle receives the alignment fields in such a way that the motor vehicle detects the local signal strength and the frequency of the alignment fields.
- the stronger alignment field and the alignment frequency of the stronger alignment field are used to detect that the mobile induction charging device must be aligned with the induction charging device associated with the parking area.
- a navigation instruction for aligning the motor vehicle on the parking area is then issued.
- At least two of the alignment fields are expediently generated with the same signal strength and thus intensity.
- alignment refers in particular to driving the motor vehicle onto the parking area and thus in particular to approaching the mobile vehicle To understand the induction charging device for the stationary induction charging device and the correct angular positioning.
- the parking direction expediently runs parallel or along the longitudinal extent of the associated parking area.
- Approaching a parking area usually occurs when the motor vehicle moves in the direction of the parking area.
- Navigation using the navigation instructions can begin in particular when the motor vehicle has reached an outer edge of the parking area and/or the stationary induction charging device.
- the stationary induction charging devices are advantageously spaced apart from one another.
- the stationary induction charging devices of the respective transverse row and the respective longitudinal row are spaced apart from one another.
- At least two parking areas of at least one of the transverse rows directly touch each other, in particular merge directly into one another.
- a road runs between at least two of the longitudinal rows. It is conceivable that at least two parking areas of at least one of the transverse rows are immediately spaced apart from one another, that is to say that no road runs between the parking areas.
- the stationary induction charging devices of the respective transverse rows generate the alignment field alternately with the first alignment frequency and the second alignment frequency.
- the stationary induction charging devices of the parking areas of the longitudinal rows preferably generate the alignment field with the same alignment frequency.
- the parking space can have at least three such transverse rows and at least two such longitudinal rows.
- the stationary induction charging devices of the parking areas generate the alignment field along the transverse rows and along the longitudinal rows with alternating alignment frequencies, so that in one of the transverse rows the stationary induction charging devices of the parking areas alternating the alignment field with a first alignment frequency and a second alignment frequency, and in the adjacent transverse row the stationary induction charging devices of the parking areas generate the alignment field alternately with a third alignment frequency and a fourth alignment frequency.
- the stationary induction charging devices of one of the transverse rows generate the alignment fields with a first sequence with alternating first alignment frequency and second alignment frequency and the stationary induction charging devices of the adjacent transverse row with a second sequence with alternating the third alignment frequency and the fourth alignment frequency, wherein the first sequence and the second sequence of successive transverse rows alternate.
- the stationary induction charging devices of the parking areas generate the alignment field either alternately with the first alignment frequency and the third alignment frequency or with the second alignment frequency and the fourth alignment frequency.
- the respective stationary induction charging device thus generates the associated alignment field with an alignment frequency that differs from the alignment frequencies of the immediately adjacent mobile stationary induction charging devices.
- the respective alignment field can in principle be of any type.
- the respective alignment field is a magnetic field, in particular an alternating magnetic field. This means that the respective mobile induction charging device generates a magnetic alignment field. This results in a simple creation of the alignment field, whereby the alignment field can at the same time be received in a simplified manner on the motor vehicle side and is stable.
- the respective induction charging device can have a corresponding coil, which is also referred to below as an alignment coil.
- the alignment coil is advantageously wound around a winding axis that runs parallel to the parking direction.
- Embodiments are considered preferred in which at least one of the alignment fields widens along the associated parking direction starting from the associated stationary induction charging device, in particular starting from the associated alignment coil. In particular, it can only be a slight widening, which results from the alignment fields diverging as the distance from their source, namely the alignment coil, increases. This means that a motor vehicle receives the alignment field even if it approaches the associated parking area at an angle or an incline to the parking direction and not or not only the alignment field of the adjacent stationary induction charging device. This means that the alignment or the output of the navigation instructions can be carried out reliably even during such a start.
- the respective alignment field widens, starting from the associated stationary induction charging device, in particular starting from the associated alignment coil, along the associated parking direction.
- the respective alignment field is used for remote positioning of a mobile induction charging device to the stationary induction charging device associated with the parking area being approached.
- Remote positioning is preferably carried out at distances between the Induction charging devices over 0.5 m, in particular over 1.5 m. When positioning in the far field, the induction charging devices are roughly positioned relative to one another.
- the respective stationary induction charging device also generates a field which is directed parallel to the normal of the plane of the associated parking area, in particular out of the plane of the associated parking area, and is also referred to below as a positioning field.
- a positioning field is directed in the height direction.
- the respective motor vehicle can receive the positioning field. This means in particular that the respective motor vehicle recognizes the local intensity of the positioning field.
- a navigation instruction for positioning the mobile induction charging device of the motor vehicle to the stationary induction charging device of the parking area being approached is issued.
- the positioning of the induction charging devices relative to one another advantageously serves the purpose of not only bringing the induction charging devices closer to one another, but also aligning them to one another in the plane of the parking area.
- the mobile induction charging device is positioned close to the induction charging device associated with the parking area approached by means of the positioning field. Close positioning is to be understood as meaning a more precise positioning of the induction charging devices relative to one another, particularly in comparison to long-distance positioning.
- the close positioning preferably takes place after the long-distance positioning.
- the close positioning therefore begins in particular at distances between the induction charging devices of less than 0.5 m, in particular less than 0.3 m.
- the respective stationary induction charging device preferably generates the positioning field with four or five coils that are spaced apart from one another and each generate a magnetic field. This means that the positioning field is made up of four or five magnetic fields that are offset from one another.
- the induction charging devices can be positioned in at least two mutually transverse directions, in particular in the parking direction and transverse to the parking direction. This leads to a more precise and easier positioning of the induction charging devices relative to one another and consequently to increased efficiency.
- the magnetic fields or magnetic fields of the positioning field are each generated with an associated frequency, which is also referred to below as the positioning frequency. If a positioning field therefore comprises four magnetic fields, one of the magnetic fields is generated with a first positioning frequency, one of the magnetic fields with a second positioning frequency, one of the magnetic fields with a third positioning frequency and one of the magnetic fields with a fourth positioning frequency . If the positioning field comprises five magnetic fields, these will each have an associated positioning frequency, i.e. a magnetic field with a first positioning frequency, a magnetic field with a second positioning frequency, a magnetic field with a third positioning frequency, a magnetic field with a fourth Positioning frequency and a magnetic field with a fifth positioning frequency are generated.
- the motor vehicle in particular the mobile induction charging device, can differentiate between the positioning frequencies. This results in a simple and reliable positioning of the induction charging devices relative to one another.
- the induction charging device generating the magnetic fields of the positioning field preferably has an associated coil, preferably a flat coil, for generating the respective magnetic field, which is preferably wound in the plane or parallel to the plane of the associated parking area and/or around a winding axis running parallel to the normal of the parking area.
- an associated coil preferably a flat coil
- the induction charging device generating the magnetic fields of the positioning field preferably has an associated coil, preferably a flat coil, for generating the respective magnetic field, which is preferably wound in the plane or parallel to the plane of the associated parking area and/or around a winding axis running parallel to the normal of the parking area.
- the positioning is preferably carried out using the magnetic fields of the positioning field by forming a ratio between two of the magnetic fields and outputting the navigation instruction based on the ratio. This leads to a robust implementation of navigation with increased reliability.
- the respective navigation instruction can be made available to a vehicle driver who can drive, in particular steer, the motor vehicle in accordance with the navigation instruction in order to achieve the alignment.
- the respective navigation instruction can be output to a driving assistance system for at least partially autonomous driving of the motor vehicle, so that the driving assistance system drives the motor vehicle at least partially autonomously using the navigation instruction.
- the respective positioning frequency differs from the respective alignment frequency of the respective alignment field. An improved transition between the long-distance positioning and the close-up positioning can therefore take place and/or there is no negative influence between the long-distance positioning and the close-up positioning.
- the magnetic fields of the positioning field of the respective stationary induction charging device are generated with the same positioning frequencies.
- the system therefore requires a reduced number of frequencies or a smaller frequency band overall.
- the respective frequency is preferably in the kilohertz range. As mentioned above, it is preferred if the frequencies differ from each other. In particular, it is conceivable that adjacent frequencies in the frequency band differ from each other by 0.4 kHz to 1 kHz.
- the first alignment frequency is advantageously 134.0 kHz or 135.0 kHz or 145.560 kHz.
- the second alignment frequency is advantageously 135.5 kHz or 136.5 kHz or 137.0 kHz or 145.985 kHz.
- the third alignment frequency is advantageously 133.5 kHz or 146.843 kHz.
- the fourth alignment frequency is advantageously 137.0 kHz or 137.5 kHz or 147.275 kHz.
- the first positioning frequency is advantageously 111.483 kHz or 134.5 kHz.
- the second positioning frequency is advantageously 111.982 kHz or 136.0 kHz or 136.5 kHz.
- the third positioning frequency is advantageously 112.994 kHz or 135.0 kHz.
- the fourth positioning frequency is advantageously 113.507 kHz or 135.5 kHz or 136.0 kHz.
- the respective motor vehicle especially the respective mobile one
- Induction charging device advantageously has for receiving the alignment fields and/or the positioning fields have an appropriately equipped receiver.
- the receiver can have at least one receiving coil.
- the at least one receiving coil is different from the energy coil of the associated mobile induction charging device.
- the method is advantageously implemented using a computer program product.
- the computer program product expediently contains instructions which, when executed on a computer system, result in the method being carried out as described.
- the computer program product is preferably stored at least partially in the respective motor vehicle, in particular in the respective mobile induction charging device.
- the computer program product is preferably at least partially executed in the respective motor vehicle, in particular in the respective mobile induction charging device.
- the motor vehicle in particular the mobile induction charging device, can at least partially comprise the computer system.
