DETAILED DESCRIPTION

Vehicle parking is getting more convenient for users with modern vehicle parking systems. For example, parking spaces may have indicators helping drivers to find a free parking space without a need to circle around a parking lot when searching a free slot. The indicators may be, for example, lamps installed above each parking space which change color form green to red when a sensor associated with the parking space recognizes that a vehicle has parked in the respective parking space. There are also parking space reservation solution showing, for example, with a mobile device application which parking places are taken and which parking spaces are still free. The mobile device application may receive information from a system that receives information from the sensors associated with the parking spaces or update the parking situation based on reservations received from other users via the application. Parking lots may also have a camera surveillance solution which may be automatically monitored or manually monitored by an operator providing updates on the prevailing parking situation. Typically, the parking lots are associated with a building, and the users of the parking spaces may proceed to elevators of the building for their final destination.


According to an embodiment, a method enables controlling an elevator system of a building based on vehicle parking information associated with at least one parking space of the building. The method may be performed, for example, by an apparatus, a controller or an elevator controller. The apparatus or controller may be an internal or an external element of the elevator system. The external element may refer, for example, to a cloud based controller or other controlling entity. The vehicle parking information may indicate that at least one parking space is occupied. The vehicle parking information may further comprise additional information, for example, that the parking space is dedicated to a specific user or user category. The vehicle parking information may be provided as an input for elevator control. This enables a solution in which probable elevator calls may be anticipated and elevators may be controlled accordingly. Further, preferences and needs of the specific users or user categories may be taken into account in the elevator control in response to a parking space associated with the user being occupied. Enhanced service and ease of use of the elevators for the specific users may be provided in a timely manner based on the vehicle parking information.

FIG. 3A illustrates an example of a first parking floor 300 of a building associated with a vehicle parking management system according to an embodiment. The first parking floor 300 may comprise a number of parking spaces 302, 304A, 304B, 304C, 306, 310. Each parking space 302, 304A, 304B, 304C, 306, 310 may comprise a sensor 308 configured to indicate reservation state of the parking space 302, 303, 304A, 304B, 304C, 310. The sensors 308 may be coupled with indicators, such as LEDs changing color in response to a vehicle detected by the sensor 308 at the parking space. The LEDs may provide guidance for drivers to find free parking spaces. In FIG. 3A, the reservation state of the parking spaces 302, 304A, 304B, 304C, 306, 310 is indicated with dark colored sensors 308 (occupied) and light colored sensors 308 (free). The sensor data may be stored in the vehicle parking management system 200 and provided for an apparatus 100 configured to control an elevator system of the building. The elevator system may comprise one or more elevators 312A, 312B.


The parking floor 300 may comprise dedicated parking spaces, for example, parking spaces reserved for disabled persons 304A, 304B, 304C and parking spaces reserved for specific users 302, 306. The specific users may comprise, for example, a CEO having an office at the building. The parking floor 300 may also comprise parking spaces 306 reserved for a specific user category, for example, for customers of a car rental company or employees of a company having an office at the building. The specific user category may have, for example, special needs or repetitive habits. The special needs may comprise, for example, requirements typical for disabled persons or personal preferences. The repetitive habits may comprise, for example, a usual destination floor of the user.


The vehicle parking management system 200 may send vehicle parking information each time a state of any of the sensors 308 indicates that a vehicle has parked to a parking space. The vehicle parking information associated with at least one parking space 302, 304A, 304B, 304C, 306, 310 of the building may be received by the apparatus, which may comprise the apparatus 100. The vehicle parking information may indicate that the at least one parking space is occupied. The apparatus may then control the elevator system based on the vehicle parking information. In an embodiment, the apparatus 100 may determine at least one element of the elevator system is to be controlled based on a location of the at least one parking space. The element may be, for example, an elevator car or an elevator parameter. The elevator parameter may be, for example, an elevator car door parameter or an elevator control parameter. The elevator car door parameter may comprise a door time determining for how long the elevator car doors stay open before closing. The elevator control parameter may be associated to, for example, a parking floor of an elevator car, prioritizing an elevator call, initiating an elevator call, initiating a destination call or adjusting elevator traffic forecasts.


For example, a vehicle 314 may have arrived at a parking space for disabled persons 304C. When the vehicle 314 parks at the parking space 304C, the sensor 308 associated with the parking space 304C may transmit data to the vehicle parking management system 200 indicating that the parking space 304C is now reserved. In response, the apparatus 100 may receive the vehicle parking information comprising the reservation data. The reservation data may comprise start time of the parking and location of the parking space 304C. In an embodiment, the vehicle parking information may further comprise additional information associated with the parking space 304C. Alternatively, the vehicle parking information may only comprise the indication that the specific parking space is occupied, and the apparatus 100 may have a stored record comprising the additional information associated with specific parking spaces.


In an embodiment, the additional information may comprise an indication that the parking space is associated with a predefined user category. The predefined user category may comprise a disabled person category. The apparatus may control the elevator system based on the predefined user category. In an embodiment, the apparatus 100 may change elevator door parameters of the elevator which receives an elevator call to the parking floor 300 associated with the parking space 304C. The door parameters may be changed, for example, to extend the time the elevator doors stay open such that the disabled person may have more time to enter and leave the elevator. The apparatus 100 may be configured to switch the door parameters back to the initial door parameters after the user has left the elevator. In an embodiment, the apparatus 100 may initiate at least one of voice control or voice guidance to help visually impaired people use the elevator. The voice control may enable the user to operate the elevator with voice commands. The voice guidance may instruct the user about opening and closing of the elevator car doors, current floor of the elevator, and the destination floor of the elevator. In an embodiment, the apparatus 100 may control passenger capacity of the elevator such that there is sufficient space reserved for the disabled person, possibly using a wheelchair. In an embodiment, the apparatus 100 may control the elevator system based on the vehicle parking information and current elevator traffic situation. The elevator door times may be adjusted only if the prevailing elevator traffic situation allows to do so, e.g. outside peak times of the elevator traffic.


In an embodiment, the vehicle parking information may comprise an estimated walking time to a nearest elevator from the parking space. For example, a second vehicle 316 may have parked to a regular parking space 318 just before the first vehicle 314 arrived at the parking space 304C reserved for disabled persons. The vehicle parking information received by the apparatus 100 may comprise the locations of the parking spaces 304C, 318, start times of parkings and estimated walking times from the parking spaces 304C, 318 to the nearest elevator 312B. Hence, even though the second vehicle 316 arrived first, the apparatus 100 may control the elevator 312B to serve first the user of the first vehicle 314 as the user may reach the elevator 312B first. The estimated walking times associated with each parking space may be received from the vehicle parking management system 200 or stored on the apparatus 100. The walking times may be also estimated by the apparatus based on locations of the parking space and the elevator.


In an embodiment, the apparatus 100 may control parking of an elevator car in an elevator shaft based on the vehicle parking information. For example, based on the two recently reserved parking spaces 304C, 318 at the first parking floor 300, the apparatus 100 may determine that an elevator call is expected from that floor. Hence, the apparatus may control at least one of the elevators 312A, 312B to park to that floor such that there is an elevator waiting for the probable new elevator car call. The vehicle parking information may also indicate that another vehicle has parked in another floor and the apparatus 100 may be configured to park the elevator to the floor associated with an occupied parking space having the shortest estimated walking time to the nearest elevator. The shortest estimated walking time may indicate a highest probability of a new elevator car call. Therefore, elevator traffic may be optimized by estimating probable elevator calls as well as service order of the elevator car calls based on the vehicle parking information.


In general, the vehicle parking information may serve as an indicator of a probable elevator call from a floor associated with the at least one parking space being recently occupied. In an embodiment, the apparatus 100 may be configured to make an elevator call based on the vehicle parking information. This enables a solution in which a waiting time of the elevator may be decreased. The elevator call may be made after a certain threshold. The threshold may be preset, for example, based on an average time it takes for a user to arrive at the elevator from the parking spaces, or the threshold may be determined based on the estimated walking time from the specific parking space to the elevator.


In an embodiment, a vehicle 320 may have parked to a parking space 302 reserved to a specific user. In response, the sensor 308 at the parking space 302 may transmit vehicle parking information associated with the parking space 302 indicating that the parking space is now occupied. The parking space 302 and respective vehicle parking information may be associated with additional information indicating that it is reserved for the specific person. After receiving the vehicle parking information, the apparatus 100 may control the elevator system based on the specific user. In an embodiment, the apparatus 100 may make an elevator call based on the parking information to the floor associated with the parking space 302. In an embodiment, the apparatus 100 may reserve one of the elevators 312A, 312B to serve only this specific user. In an embodiment, the elevator call may comprise making a destination call to a destination floor associated with the specific user.


For example, the specific user may be a chief executive officer (CEO) of a company having headquarters at the building. The CEO may want to have a private elevator to take him/her to the headquarters locating in an upper floor of the building. When the apparatus 100 receives the indication that the parking space 302 of the CEO is occupied, the apparatus 100 may reserve an empty elevator car to pick him/her up from the floor associated with the parking space 302 and take him/her to the floor of the headquarters. In an embodiment, the apparatus 100 may prioritize the elevator call associated with the parking space 302 such that it is served first despite of capacity and current traffic situation of the elevator system. The vehicle parking information may comprise any preferences of the specific user, such as the private elevator ride, fast service, and the destination floor of the specific user. Alternatively, the preferences of the user associated with a dedicated parking space may be stored on the apparatus 100. Control instructions associated with a certain parking space may be also associated with a specific user category. For example, the parking floor 300 may comprise one or more reserved parking spaces 306, for example, to customers or employees of a specific company. The parking spaces 306 may be, for example, associated with a floor of the company as a preset destination floor for an elevator call.



FIG. 3B illustrates an example of a second parking floor 32 of the building associated with the same vehicle parking system and elevator system as illustrated in FIG. 3A. The second parking floor 332 may comprise regular parking spaces 324 and parking spaces dedicated for specific users or user categories 322A, 322B, 326.


The elevator system may further comprise a freight elevator 328. When a vehicle 330 parks at a parking space 326 reserved for loading and unloading goods, the apparatus 100 may make an elevator call to the second parking floor 320 for the freight elevator 328. Hence, the vehicle parking information associated with the parking space 326 may cause the apparatus 100 to control a specific elevator 328 of a plurality of elevators 312A, 312B, 328.


The specific user category may comprise, for example, passengers of buses. The vehicle parking information associated to the parking spaces 322A, 322B reserved for a bus may be used by the apparatus as an indicator that heavy traffic may be expected by the elevators 312A and 312B at the second parking floor 332. The apparatus 100 may be configured to reserve elevator capacity to serve a plurality of passengers based on the vehicle parking information. In an embodiment, the apparatus 100 may control the elevator system to park one or more of the elevators 312A, 312B in an elevator shaft at or close to the second parking floor 332 based on the vehicle parking information associated to the parking space 322A, 322B. Hence, the elevator 312A, 312B may be readily waiting for a probable elevator call from passengers of a bus parked at the parking space 322A, 322B. Alternatively, or in addition, the apparatus 100 may make one or more elevator calls to the second parking floor 332 for the passengers. The building may comprise, for example, a hotel, and the apparatus 100 may make a destination call to a floor where the reception of the hotel locates if the specific user category is associated with new hotel guests.


In an embodiment, the vehicle parking information may indicate full occupancy of the parking floor 332 associated with the at least one parking space 322A, 322B, 324, 326. The apparatus 100 may use the vehicle parking information as an indicator that no elevator passenger traffic is expected from a floor associated with the at least one parking space 322A, 322B, 324, 326. For example, when the elevator 312A, 312B, 328 has served a user associated with the last free parking space at the second parking floor 332, the apparatus 100 may determine that no further elevator calls may be expected from the second parking floor 332 because there are no free parking spaces left. In response to the vehicle parking information indicating that all parking spaces 322A, 322B, 326 of the second parking floor 332 are occupied, the apparatus 100 may control the elevator system to park the elevators to other floors having a higher probability of a new elevator call. This enables a solution in which waiting times for an elevator car may be decreased as the elevator car may already be at the floor from which the next elevator car call may be expected.



FIG. 4 illustrates a method for controlling an elevator system based on vehicle parking information according to an embodiment. The method may be implemented, for example, by the apparatus 100. The apparatus may be an elevator controller or another controller that may be an internal or an external element of the elevator system. The external element may refer, for example, to a cloud based controller or other controlling entity.


At 400, vehicle parking information associated with at least one parking space of a building is received, the vehicle parking information indicating that the at least one parking space is occupied. The vehicle parking information may be received from an automated vehicle parking management system 200 or an operator 202 of a vehicle parking management system. The vehicle parking management system 200 may have one or more sensors configured to provide information on occupancy of one or more parking spaces of a building.


At 402, at least one element of an elevator system to be controlled may be determined. The at least one element may comprise, for example, a component or a parameter of the elevator system.


At 404, the elevator system is controlled based on the vehicle parking information. Controlling the elevator system may comprise, for example, adjusting elevator traffic predictions based on the vehicle parking information at 406. In an embodiment, the vehicle parking information may comprise an indication that there is a high arrival rate of vehicles to a specific floor in the building. The high arrival rate of vehicles may indicate unexpected or increased traffic to the specific floor. The vehicle parking information may be used to adjust or optimize elevator passenger traffic predictions made based on previous elevator passenger traffic behavior in the building. The vehicle parking information may be used to determine a new input for the predictions such that changes compared to usual elevator traffic may be taken into account in the predictions. Further, the vehicle parking information may be used to anticipate that the next elevator call is coming from the floor associated with the entering vehicle traffic.


At 408, controlling the elevator system may comprise determining a probable new elevator call from a floor associated with the at least one parking space. Based on the vehicle parking information, the number and origin of probable new elevator calls may be estimated to schedule the elevator traffic. In an embodiment, an elevator call may be made based on the vehicle parking information, such that an elevator may be sent in advance to a floor associated with the probable new elevator car. In an embodiment, the vehicle parking information may comprise additional information associated with the parking space indicating a probable destination of the user of the parking space. Hence, a destination call from the floor of the parking space to the destination floor of the user may be made based on the vehicle parking information. The additional information may comprise an estimated walking time to a nearest elevator from the parking space, or a walking time may be estimated based on location of the parking space. The elevator call may be dispatched after a threshold set based on the walking time.


At 410, controlling the elevator system may comprise controlling parking of one or more elevators in one or more elevator shafts. The parking of elevators may be controlled based on the probable new elevator car call such that the elevator is park to the floor from which the elevator car call is expected. In an embodiment, the vehicle parking information comprises an indication that a parking floor associated with the at least one parking space is fully occupied. Based on this it may be determined that no elevator car calls are to be expected from that floor. Hence, it may be determined that elevators are not parked to the fully occupied parking floors, but to other floors having a higher probability of a new elevator car call.


At 412, it may be determined if the parking space is associated with a predefined user or user category. If not, i.e. the parking space is a regular parking space, a normal elevator call may be made to the floor associated with the parking space at 414. If the parking space is associated with a predefined user or user category, preset service preferences associated with the user or user category may be determined at 416. At 418, an elevator or elevator call may be prioritized for the user based on the service preferences. Prioritizing the elevator call may comprise overriding previous elevator calls to serve the user first. Prioritizing the elevator may comprise reserving the whole elevator, or a certain space at the elevator, for the user. In addition, or alternatively, at 420 the service preferences may comprise adjusting elevator door parameters for an elevator trip associated with the user category. In addition, or alternatively, at 422 the service preferences may comprise enabling a voice control and guidance for an elevator trip associated with the user category. The elevator trip may comprise the time from an elevator call until it is estimated that the user has left the elevator. At 414, an elevator call may be made for the specific user or user category based on the service preferences. The service preferences may also comprise a destination floor of the specific user or user category, and the elevator call may comprise a destination call to the destination floor. Hence, the elevator service may be applied in accordance with requirements or preferences of the specific user or user category based on the vehicle parking information.


The method enables using vehicle parking information as an input for elevator control such that the input may be taken into account in controlling elevator traffic and the elevators. For example, elevator calls, specialized service and optimization of elevator traffic may be enabled based on the vehicle parking information. The vehicle parking information may enable providing enhanced elevator service for users with different needs or requirements simply in response to receiving an indication about occupancy of a parking space associated with the user. The method may use information associated to vehicle parking spaces in a novel way to control an elevator system.
