RELATED APPLICATION DATA 
     This application is a continuation of International Patent Application No. PCT/CN2020/115939, filed Sep. 17, 2020, which claims the benefit of European Patent Application No. 19201289.6, filed Oct. 3, 2019, the disclosures of which are incorporated herein by reference in their entireties. 
    
    
     TECHNICAL FIELD 
     The present invention relates to a central locking system for locking a vehicle, a vehicle system, a method for controlling a central locking system and a computer program. 
     BACKGROUND 
     Today, in addition to a vehicle, it is also common and possible to have several different add-ons. Such add-ons may e.g. be roof boxes, trailers, bike holders, caravans and the like. It is also typically common that these add-ons are equipped with a lock in order to keep their content safe from e.g. theft, or stopping the content from falling out when the vehicle is in transit. 
     For each add-on a user is typically required to carry a corresponding key in addition to the key for the lock of the vehicle. Furthermore, the user is typically required to manually check each lock for each respective add-on in order to determine whether the add-on is locked and/or attached or not. 
     U.S. patent application Ser. No. 18/024,9130 A1 describes a method for ensuring the safety of goods transported on a highway using a smart phone hub, a portable sensor for monitoring the transported goods and a physical locking mechanism for locking the trailer comprising the goods. The smart phone hub, portable sensor and locking mechanism are managed by a remote central monitoring hub. The locking mechanism may be a Bluetooth lock, and the status of the lock may hence be monitored. 
     However, a problem with the above disclosure is that a user is required to be very close to the lock of the trailer in order to lock/unlock and monitor it. 
     There is thus a need for an improved locking mechanism for vehicles and their add-ons.

       FIG. 1  shows a central locking system  1  for locking a vehicle  2 . The central locking system  1  comprises a central locking unit  10 , at least one vehicle lock  20  of the vehicle  2 , wherein the vehicle lock  20  is connected to the central locking unit  10  and arranged to be regulated by the central locking unit  10  between a locked and unlocked position (which positions will be described further in conjunction with  FIGS. 2A-2D ). A mobile device  30  is configured to wirelessly connect to the central locking unit  10  and to control the central locking unit  10  to regulate the vehicle lock  20  between the locked and unlocked position. The central locking system  1  comprises at least one remote lock  40  of the remote unit  4  for locking a remote unit  4  configured to be detachably connected to the vehicle  2 , wherein the remote lock  40  of the remote unit  4  is configured to be connected to the central locking unit  10  and arranged to be regulated by the central locking unit  10  between a locked and unlocked position (which positions will be described further in conjunction with  FIGS. 2A-2D ). The mobile device  30  is configured to control the central locking unit  10  to regulate the remote lock  40  of the remote unit  4  between the locked and unlocked position L 2 , U 2 . 
     Hence  FIG. 1  illustrates a vehicle system  100  comprising a vehicle  2 , one or more remote units  4  detachably connected to the vehicle  2  and the central locking system  1  according to some embodiments. 
     In  FIG. 1  the vehicle is illustrated to be a car having a door and a trunk. It should be realized the vehicle may be of any other type such as e.g. a truck, a tractor, a recreational vehicle, a carriage, a boat, a minivan, motor cycle, a moped, a bicycle, a train, an airplane, a helicopter, etc. Furthermore  FIG. 1  illustrates two vehicle locks  10 , one for the door and one for the trunk. It should be noted that fewer or additional vehicle locks are possible, such as e.g. a lock for the glove compartment, a lock for a back door, etc. 
     The remote unit  4  is in  FIG. 1  illustrated to be a roof box, but could be of other types, such as a trailer, a bicycle holder, a caravan, a carriage, a ski box etc. 
     The central locking system  1  in  FIG. 1  comprise two vehicle locks  20  and one remote lock  40  of the remote unit  4 , as indicated by the dashed square. The locks may be connected wirelessly but may also be connected through wire to each other and/or to the central locking system  1 . E.g. by being connected to the central locking unit  10 . In some embodiments, the vehicle locks  20  may be connected through electrical wires within the vehicle  2 , and may have been connected during manufacturing of the vehicle. In some embodiments, the vehicle locks may additionally or alternatively be connected to the central locking system  1  wirelessly. In the same manner, the remote lock  40  of the remote unit  4  may be connected wirelessly or by wire to the central locking system  1 . The central locking system  1  may e.g. have inputs for receiving an electrical cable and the remote lock and/or the remote unit may be equipped with a cable for connecting to the outputs of the central locking system  1  in order to connect the remote lock to the central locking system. The inputs may e.g. be arranged in the central locking unit  10 , and/or arranged in a circuitry within the vehicle. 
     A user  33  is seen holding the mobile device  30 . The mobile device may e.g. be a smart phone, a tablet, a laptop, a computer or similar (as illustrated in  FIG. 1 ). The mobile device may in some embodiments be a key fob. The key fob may e.g. be associated with the vehicle  2 . The key fob may e.g. be configured to control the vehicle lock  20  and the connected remote lock  4  by means of the centralized locking system  1 . 
     The mobile device may comprise a mobile connection unit  31  configured to connect to the central locking system. The mobile device  30  may also comprise an application, wherein the application is configured to control the central locking unit  10  to regulate the vehicle lock  20  and the remote lock  40  of the remote unit  4  between their locked and unlocked position L 1 ,L 2 ;U 1 ,U 2 . 
     In some embodiments, the mobile connection unit  31  is e.g. a transceiver circuitry configured to search for and pair against the central locking system  1 . Once connected to the central locking system, the mobile connection unit  31  may be configured to receive control input from the user  33  for controlling the vehicle lock and/or the remote lock. In the same manner, once connected to the central locking system, the mobile connection unit  31  may be configured to receive data pertaining to the status of the vehicle lock and/or the remote lock from the central locking system  1 . The transceiver circuitry may e.g. comprise an antenna configured to transmit and receive signals. In some embodiments, the transceiver circuitry is a receiver circuitry and a transmitter circuitry separate from each other. 
     The mobile connection unit  31  may utilize a Bluetooth connection (i.e. a Bluetooth unit) and or a near field communication, NFC connection (i.e. a NFC-unit). In some embodiments, the mobile connection unit may utilize a wireless communication network connection (e.g. LAN, WAN, WLAN, cloud connection, internet connection etc. provided e.g. by a network operator). 
     In some embodiments, the mobile device  30  may comprise a user interface  32  and the mobile device  30  may be configured to display the status of the vehicle lock  20  and the remote lock  40  of the remote unit  4  on the user interface  32  of the mobile device  30 . In some embodiments, the user interface  32  may be provided by the application. The application may in some embodiments be downloaded and installed on the mobile device. 
     In some embodiments, the application may be configured to be controlled by the user through the interface  32 . The interface  32  may e.g. illustrate the status of the vehicle lock  20  and the remote lock  4  by means of an image of an opened or closed padlock (or other type of lock). The interface  32  may further be configured to display various control options such as “lock/unlock”; “lock/unlock a specific lock connected to the central locking system (such as only the vehicle lock attached to the vehicle door, or only the remote lock etc.)”; “lock/unlock all locks connected to the central locking system”. The interface  32  may receive input from the user  33 , which is transferred to the mobile connection unit  31  for transmission to the central locking system  1 . 
     In some embodiments, the user interface  31  is configured to receive input from a user  33  of the mobile device  30  to control the central locking unit  10  to regulate the vehicle lock  20  and the remote lock  40  of the remote unit  4  between the locked and unlocked position L 1 ,L 2 ,U 1 ,U 2 . 
     Hence, the user is enabled to control all locks connected to the central locking system  1  and/or controlled by the central locking unit  10 . The user may e.g. choose to lock or unlock one or more locks regardless of the status of the other locks. Thus, the user is enabled to lock/unlock e.g. only the remote lock, or only one or more of the vehicle lock  20  (e.g. only the lock attached to the trunk, or only the lock attached to the door). The user may also be enabled to lock/unlock all locks connected to the central locking system  1  simultaneously. 
     By means of the interface, the user is enabled to quickly determine which locks are locked/unlocked as well as quickly lock/unlock the locks connected to the central locking system. In some embodiments, the application may be configured such that when the user locks/unlocks the vehicle lock, the remote locks are automatically locked/unlocked as well. Hence, the central locking system integrates any remote lock into the central locking system of the vehicle, ridding the need for several different keys to each lock. The central locking system according to the embodiments herein further enhances a sense of security for the user, since the user will know that if the vehicle lock  20  is locked, then also the remote lock  4  is locked. Hence, the user will not have to worry about forgetting locking the remote unit. 
     Furthermore, by means of the interface, the user is enabled to check the status of the vehicle lock and remote lock during transit of the vehicle. The user may e.g. operate a vehicle which is not easily parked (such as e.g. an airplane or other flying vehicle etc.), or the user is not enabled to exit the vehicle (the user may e.g. be in a road tunnel or there is excessive rain pouring down etc.) but would still like to check the status of the locks. Then, by using the mobile device the user is enabled to easily determine and control the status of the vehicle lock and remote lock without having to stop/park or even leave the interior of the vehicle. 
     In some embodiments, the remote lock will always follow the status of the vehicle lock. Hence in an application where the vehicle is configured to lock itself e.g. if has been unlocked for a predetermined amount of time (possibly based on some logic, e.g. no door has been opened), the remote lock will automatically lock when the vehicle lock is automatically locked. This may also apply to the remote lock if the vehicle lock is configured to lock automatically when the vehicle is in transit. 
     The above embodiment may be a setting, which the user can apply through the mobile device. Hence, a user may choose to have individual control over every respective lock connected to the central locking system while still allowing automatic locking of the remote locks if the vehicle lock(s) is automatically locked. 
       FIGS. 2A-2D  illustrates the locking unit  10  and the remote locking unit  40  in more detail according to some embodiments. The locking unit  10  and locking unit  40  of  FIGS. 2A-2D  may e.g. be the locking unit  10  and locking unit  40  as described in conjunction with  FIG. 1 . 
       FIG. 2A  schematically illustrates the central locking unit  10  in an unlocked U 1  state. The central locking unit  10  comprises a mobile connection unit  12  configured to connect to a mobile connection unit of a mobile device (e.g. the mobile device  30  and mobile connection unit  31  described in conjunction with  FIG. 1 ). 
     In some embodiments, the central locking unit may comprise a vehicle lock  20  (e.g., the vehicle lock as described in conjunction with  FIG. 1 ). The vehicle lock  20  may in some embodiments comprise an electrically operable locking hatch  22 . The vehicle lock  20  may in some embodiments comprise a controlling circuitry  13  (e.g. a controller). The controlling circuitry may e.g. be controlled by the central locking unit  10 , based on received inputs from e.g. the mobile connection unit  12 , to cause movement of the locking hatch  22  between an unlocked state UL1 and a locked state L 1 . Hence, the mobile connection unit  12  may in some embodiments relay user inputs for locking/unlocking the vehicle lock  20  and/or a remote lock. 
       FIG. 2A  illustrates the central locking unit  10  where the locking hatch  22  is in the unlocked state U 1 , whereas  FIG. 2B  illustrates the central locking unit  10  where the locking hatch  22  is in the locked state L 1 . 
     The controlling circuitry  13  may be configured to control all vehicle locks. The controlling circuitry  13  may e.g. be configured to control door locks, trunk locks, glove compartment locks etc. In some embodiments, the controlling circuitry  13  is integrated with and comprised by the mobile connection unit  12 . 
     The mobile connection unit  12  may e.g. be a transceiver circuitry configured to search for and pair against the mobile connection unit  31  of the mobile device (compare with  FIG. 1 ). Once connected to the mobile device, the mobile connection unit  12  may be configured to receive control input from the mobile device for controlling the vehicle lock and/or the remote lock. In the same manner, once connected to the mobile device, the mobile connection unit  12  may be configured to transmit data pertaining to the status of the vehicle lock and/or the remote lock to the mobile device. The transceiver circuitry may e.g. comprise an antenna configured to transmit and receive signals. In some embodiments, the transceiver circuitry is a receiver circuitry and a transmitter circuitry separate from each other. 
     The mobile connection unit  12  may utilize a Bluetooth connection (i.e. be a Bluetooth unit e.g. a Bluetooth transceiver circuitry) and or a near field communication, NFC connection (i.e. be a NFC-unit e.g. a NFC-transceiver circuitry). In some embodiments, the mobile connection unit may utilize a wireless communication network connection. Hence the mobile device may control the central locking system (e.g. by receiving inputs from and transmitting control signaling to the mobile connection unit  12  of the central locking system) even if the user is far away from the vehicle. In some embodiments, as long as the mobile device and the central locking system has access to a communication network (e.g. the internet) the user is enabled to control the locks. Hence, in some embodiments the user may park the vehicle in a parking spot and then leave the vehicle. The user may e.g. enter a work building or go on a hike, or travel on vacation etc., while still being able to survey the status of the central locking system as well as control the central locking system. 
     The central locking system  1  may further comprise a wireless communication unit  11 . The wireless communication unit  11  may be configured for connecting the central locking unit  10  to the remote lock (and thereby connect it to the central locking system  1 ). The wireless communication unit  11  may in some embodiments comprise a transmitter/receiver/transceiver/antenna circuitry for wirelessly detecting and connecting to the remote lock. In some embodiments, the wireless communication unit  11  is a blue tooth unit. In some embodiments the wireless communication unit  11  is a NFC unit, or an RFID-unit. 
     In some embodiments, the wireless communication unit  11  may be integrated with, or be the mobile communication unit  12 . 
     In some embodiments the wireless communication unit  11  and/or the mobile communication unit  12  may comprise or be integrated with the controlling circuitry  13 . 
       FIGS. 2C-2D  illustrate the remote lock  40  of the remote unit  4  according to some embodiments. The remote lock  40  of the remote unit  4  may e.g. be the remote lock as described in conjunction with any of the previous  FIGS. 1-2A-2B . 
     The remote lock comprises a first wireless communication unit  41  configured to connect the remote lock  40  of the remote unit  4  to the central locking unit  10  via a second wireless communication unit  11  of the central locking unit  10  (e.g. the wireless communication unit  11  described in conjunction with  FIGS. 2A-2B ). The wireless communication unit  41  may in some embodiments comprise transmitter/receiver/transceiver/antenna circuitry for wirelessly detecting and connecting to the central locking unit  10 . 
     In some embodiments, the first and second wireless communication units  41 ,  11  are a near field communications (NFC) or Bluetooth unit  41 ,  11 . 
     Hence, the wireless communication unit  41  may be configured to automatically and continuously search for and pair against the wireless communication unit  11  of the central locking unit  10 . Once connected, the remote lock is a part of the central locking system  1  and is controlled by the central locking unit  10 . 
     Thus, when a remote lock is in a connection range of the central locking system it may automatically be detected and connected to the central locking system. In the same manner, if the remote lock is removed from the connection range of the central locking system it may be removed from the central locking system. Hence, if e.g. the roof box is removed from the vehicle and e.g. put in storage (such as a garage), the central locking system and central locking unit will no longer control the operation of the remote lock. 
     In some embodiments, the wireless communication unit  41  may be configured to utilize a wireless communication network connection (e.g. the internet) for connecting the remote lock to the central locking system through the central locking unit. In such case the remote lock may always form a part of the central locking system once connected (and not removed by the user through the mobile device), even if the remote unit is removed from the vehicle. 
     In some embodiment, the wireless communication unit  41  is configured to receive controlling signals (control input) from the central locking unit for controlling the status of the remote lock. E.g., the wireless communication unit  41  may receive instructions indicating that the remote lock  40  of the remote unit  4  should move to a locked/unlocked position. 
     In some embodiments, the remote lock  40  of the remote unit  4  comprises an electrically operable locking latch  42  configured to be moved to position the remote lock  40  of the remote unit  4  in the locked and unlocked position L 2 , U 2 .  FIG. 2C  illustrates the locking latch  42  in the unlocked state U 2 .  FIG. 2D  illustrates the locking latch  42  in the locked state L 2 . 
     In some embodiments, the remote lock  40  of the remote unit  4  is configured to lock and unlock any of a trailer, cargos, a roof box, a cycle carrier, a padlock, a bike lock and a caravan. As mentioned previously, other items than can be attached to a vehicle are eligible to be locked and unlocked by the remote lock, such as e.g. boat motors, spare tire boxes etc. 
     In some embodiments, the remote lock  40  of the remote unit  4  may comprise a controlling circuitry  43  (e.g. a controller). The controlling circuitry may e.g. be controlled by the remote lock  40  of the remote unit  4 , based on received inputs from e.g. the wireless communication unit  41  communicating with the central locking unit  10 , to cause movement of the locking hatch  42  to move between an unlocked state U 1  and a locked state L 1 . 
     In some embodiments, the controlling circuitry  43  may additionally, or alternatively, be directly controlled by the central locking unit  10 , based on received inputs from e.g. the mobile connection unit  12 , to cause movement of the locking hatch  42  between an unlocked state U 1  and a locked state L 1 . The controlling circuitry  43  may hence be controlled by the controlling circuitry  13  and/or the mobile connection unit  12  of the central locking system. 
     In some embodiments, the controlling circuitry  43  may communicate with the central locking unit e.g. through the wireless connection devices  41 ,  11  for receiving inputs for controlling the electrically operable locking hatch  42  to move between the locked state L 2  and the unlocked state U 2  (i.e. position the locking hatch in locked position and/or an unlocked position). 
     In some embodiments, the remote lock  40  of the remote unit  4  is at least one of a lock that is configured to lock and unlock the remote unit  4  to the vehicle  2 , a lock that is configured to lock and unlock an opening of the remote unit  4  or a lock that is configured to lock and unlock a device to the remote unit  4 . Hence, the remote lock may be for attaching/detaching the remote device to the vehicle, such as e.g. an electronic padlock holding a cargo or roof box in place. Alternatively or additionally the remote lock may be fore locking/unlocking the door or lid of the remote unit, e.g. the doors on a trailer or the lid of a roof box etc. Alternatively or additionally, the remote lock may be for attaching/detaching a device to the remote unit, such as e.g. a bike to a bike holder, a spare tire to a spare tire holder etc. 
       FIG. 3  illustrates an example method  300  according to some embodiments. 
     The method  300  may e.g. be carried out by the central locking system in cooperation with a mobile device, a remote lock of a remote unit, a user, a vehicle lock and an interface as described in conjunction with any of the previous  FIGS. 1-2A-2D . 
     The method  300  comprises receiving S 1 , in a mobile device, input comprising a desired position of a remote lock  40  of a remote unit  4  from a user  33 , receiving S 2 , in a central locking unit  10 , a control instruction comprising instructions to move the remote lock  40  of the remote unit  4  between a locked and unlocked position L 2 ,U 2  from the mobile device  30 , receiving S 3 , in the remote lock  40  of the remote unit  4 , a regulating signal from the central locking unit  10  to change the position of the remote lock  40  of the remote unit  4  between the locked and unlocked position L 2 ,U 2 . 
     Hence, according to some embodiments, in step S 1  of the method  300  the mobile device receives an input (i.e. control instruction) from the user. In step S 2  the central locking unit of the central locking system receives the input from the user via the mobile device. The input may be a control input instructing the central locking unit that the remote lock is to be put in a locked position or an unlocked position. The central locking unit may receive the input through a mobile connection unit (compare with  FIG. 2A-2D ). In step S 3  the remote lock receives a regulating signal from the central locking unit instructing the remote lock to change the position between the locked and the unlocked position based on the content of the regulating signal. The remote lock may e.g. control a locking hatch (compare with  FIGS. 2A-2D ) for unlocking/locking the remote lock. 
     In some embodiments, the step S 3  may also comprise the step of the central locking unit transmitting the received input from the mobile device to the remote lock. 
     In some embodiments, the method  300  may additionally, or alternatively, comprises controlling a vehicle lock (e.g. the vehicle lock as described in conjunction with any of the  FIGS. 1-2A-2D ). Hence in step S 1  the mobile device may receive control instructions (or control input, the terms may be used interchangeably) from the user relating to a desired position of the vehicle lock (i.e. whether the user wished to lock/unlock the vehicle lock). In step S 2 , the central locking unit receives the control input from the mobile device. In step S 3  the mobile connection unit of the central locking unit receives the control input for controlling the vehicle lock and moves e.g. the locking hatch of the vehicle lock between a locked and an unlocked position based on the content of the control input. 
     In some embodiments, the step S 3  may also comprise the step of the central locking unit transmitting the received input from the mobile device to the vehicle lock. 
     Hence the method  300  may in some embodiments be applied to control either or both of the (at least one) remote lock and the (at least one) vehicle lock. 
     In some embodiments, the method  300  may optionally comprise displaying S 4  the position of a vehicle lock  20  and the position of the remote lock  40  of the remote unit  4  on a user interface  32  of the mobile device  30 . 
     In some embodiments, the method  300  may optionally comprise detecting S 5  a first near field communication unit  41  of the remote lock  40  of the remote unit  4  by a second near field communication unit  11  of the central locking unit  10  and connecting S 6  the remote lock  40  of the remote unit  4  to the central locking unit  10 . 
     The near field communication unit  41  and  11  may be a wireless communication unit (compare e.g. with  FIGS. 2A-2D ). 
     It should be noted that all though  FIG. 3  illustrates optional steps S 4 , S 5  and S 6  as following steps S 1 -S 3 , this order of the steps is just an example. For instance, in some embodiments, the steps S 5 -S 6  may be carried out prior to the step S 1 . The step S 4  may be carried out following the steps S 5 -S 6 . The steps S 4 -S 6  may, in some embodiments, be carried out simultaneously as the steps S 1 -S 3 . 
     For example, the method may comprise that the mobile device should display the status of the central locking system whenever the user requests it. In the same manner, the method may comprise detecting and connecting a remote lock to the central locking system whenever a remote lock is within connection range of the central locking system.
