[0022] Figure 1 A simplified schematic diagram of a lighting system 10 as part of a vehicle 12, such as a motor vehicle, is shown according to one embodiment of the present disclosure. The illustration shows a portion of the interior of the vehicle 12 through a side window frame 14 of the vehicle 12.

[0023] According to this embodiment, the lighting system 10 comprises a plurality of light devices 16 arranged in the area of ​​an interior roof lining 18. The lighting system 10 further comprises a closed-loop lighting system control device 20 connected to each of the light devices 16.

[0024] Furthermore, the closed-loop lighting system control device 20 is connected to a closed-loop vehicle control device 22. The connection between the closed-loop lighting system control device 20 and the closed-loop vehicle control device 22 enables vehicle status information to be transmitted from the closed-loop vehicle control device 22 to the closed-loop lighting system control device 20.

[0025] The light devices 16 are arranged in the region of the interior roof lining 18 such that they are configured to illuminate a first operating area 24A. In this case, the first operating area 24A is geometrically defined relative to a first row of vehicle seats 26, a vehicle position 28 of which is shown in the present example.

[0026] As an alternative or in addition, the light device 16 can also be arranged in the area of ​​the interior roof lining 18 so that multiple working areas 24A, 24B can be illuminated. For example, the second working area 24B can be illuminated by the light device 16. In this example, the second working area 24B is geometrically defined relative to the steering wheel 30 and / or the instrument panel 32 in the vehicle 12.

[0027] In the present example, the light device 16 is configured to ensure an illumination level of at least 400 lux in each working area 24A, 24B.

[0028] According to this embodiment, the lighting system 10 further comprises a human-machine interface 33, based on which user input can be received and transmitted to the closed-loop lighting system control device 20. For example, once the closed-loop lighting system control device 20 automatically terminates the lighting, the human-machine interface 33 can be used to re-enable the lighting of the at least one work area 24A.

[0029] Figure 2 A simplified schematic diagram of a method 34 for operating a lighting system 10 according to one embodiment of the present disclosure is shown. In step 36 of the method 34, in a lighting mode of the lighting system 10, a first operating area 24A defined by at least a first row of vehicle seats 26 of the vehicle 12 is illuminated. In step 38 of the method 34, vehicle status information is transmitted from the closed-loop vehicle control device 22 to the closed-loop lighting system control device 20. In step 40 of the method 34, in a lighting mode of the lighting system 10, lighting of at least one operating area 24A is automatically terminated based on the received vehicle status information.

[0030] According to this embodiment, the vehicle status information comprises in particular vehicle status information relating to the ignition state of the vehicle 12 and, in the present case, the vehicle speed. The corresponding vehicle status information can be detected or determined based on sensors in the vehicle 12. The closed-loop lighting system control device 20 can use this vehicle status information it receives to determine whether the lighting should be terminated automatically. This is, for example, the case if the vehicle speed of the vehicle 12 exceeds a predetermined first speed threshold. In the alternative, if the received vehicle status information only contains unacceptable vehicle status information about the ignition state of the vehicle 12 or if the vehicle status information does not include information about the ignition state of the vehicle 12, the lighting of the at least one working area 24A can be terminated automatically. Reference is made to the state table 1 regarding the control logic applied by the closed-loop lighting system control device 20.

[0031] If certain vehicle configurations exist, the method 34 advantageously automatically terminates the lighting of the first operating area 24A. For these vehicle configurations, this method 34 helps the user of the vehicle 12 not be affected by the light emissions emitted by the light device 16.

[0032] Figure 3 A simplified schematic diagram of a spatial area 42 of a vehicle 12 in the context of a lighting system 10 according to one embodiment of the present disclosure is shown. According to this embodiment, a first row of vehicle seats 26 includes a first vehicle position 28A and a second vehicle position 28B disposed laterally to the side thereof. In this case, the first row of vehicle seats 26 is the vehicle row of seats that is the shortest distance from the front of the vehicle 12 in the direction of travel of the vehicle 12.

[0033] The position of the first row of vehicle seats 26 defines a first working area 24A with respect to their spatial arrangement. In addition, the vehicle 12 includes an instrument panel 32 that defines an instrument panel area 44. In this example, the vehicle 12 also includes a steering wheel 30 that defines a steering wheel area 46.

[0034] According to this embodiment, the second operating area 24B is therefore geometrically defined by the instrument panel area 44 and / or the steering wheel area 46. The light devices 16 of the lighting system 10 are arranged in the interior roof lining 18 such that in the present case they can illuminate at least the first operating area 24A and optionally also the second operating area 24B. Of course, the vehicle 12 can also include further operating areas 24.

[0035] Certain embodiments disclosed herein, particularly the closed-loop lighting system control device 20 and the closed-loop vehicle control device 22, use circuitry (e.g., one or more circuits) to implement a standard, protocol, method, or technique disclosed herein, functionally connect two or more components, create information, process information, analyze information, create signals, encode / decode signals, convert signals, transmit and / or receive signals, control other devices, etc. Any type of circuitry may be used.

[0036] In one embodiment, circuit systems such as the closed-loop lighting system control device 20 and the closed-loop vehicle control device 22 include, among other aspects, one or more data processing devices, such as processors (e.g., microprocessors), central processing units (CPUs), digital signal processors (DSPs), application specific integrated circuits (ASICs), field programmable gate arrays (FPGAs), system-on-chips (SoCs), etc., or any combination thereof, and may include discrete digital or analog circuit elements or electronic components, or a combination thereof. In one embodiment, the circuit system includes a hardware circuit implementation (e.g., an analog circuit implementation, a digital circuit implementation, etc., or a combination thereof).

[0037] In one embodiment, the circuitry includes a combination of circuitry and a computer program product having software or firmware instructions stored on one or more computer readable memories that interact to cause the device to implement one or more of the protocols, methods, or techniques described herein. In one embodiment, the circuitry includes circuitry such as a microprocessor or a portion of a microprocessor that requires software, firmware, etc. for operational purposes. In one embodiment, the circuitry includes one or more processors or portions thereof and associated software, firmware, hardware, etc.

[0038] In the description advantageous configurations of the lighting system, the vehicle and the method are detailed, each of which alone or in (sub)combination can represent various aspects of the present disclosure. Some features are explained with respect to the device or system and other features are explained with respect to the method. These aspects should be transferred to each other in a corresponding manner.

[0039] According to one aspect, some embodiments relate to a lighting system for a vehicle. The lighting system includes at least one light device, the at least one light device being arranged in the area of ​​an interior roof lining of the vehicle and arranged so that at least one working area defined by at least a first row of vehicle seats of the vehicle can be illuminated by the at least one light device. The lighting system includes a closed-loop lighting system control device, the closed-loop lighting system control device being connected to a closed-loop vehicle control device of the vehicle and being configured to receive vehicle status information from the closed-loop vehicle control device. The lighting system is configured to automatically terminate lighting of the working area in a lighting mode of the lighting system based on the received vehicle status information.

[0040] This creates a lighting system which can prevent a portion of the vehicle interior from being illuminated in a lighting mode for a specific vehicle state. This thus ensures that for the relevant vehicle state a vehicle user is less likely to be affected by the lighting due to the light arrangement. Furthermore, the lighting system light arrangement is arranged in such a way that in particular a working area defined by the first row of vehicle seats according to their spatial arrangement is illuminated. The lighting system also ensures that the lighting of the working area can be terminated automatically. Thus, no user input is required to terminate the lighting of the working area. This improves user comfort for users of the first row of vehicle seats in the vehicle.

[0041] In the present case, the interior roof lining may be understood to mean in particular the interior trim arranged vertically at the top, or a delimitation thereof. In the present case, parts of the window trim arranged vertically at the top are also associated with the interior roof lining. In other words, the interior roof lining may include an area of ​​the interior trim of the vehicle which is arranged in or above the head area of ​​the user in the normal body position of the vehicle user.

[0042] In the present case, a first row of vehicle seats may be understood to mean the row of vehicle seats which has the shortest distance to the front of the vehicle when the vehicle is aligned straight ahead.

[0043] A vehicle row of seats usually includes a plurality of vehicle positions, which usually provide seats for people. The workspace of this person is defined with respect to the vehicle position of the vehicle row of seats according to the posture of the person arranged at the vehicle position. In this sense, the workspace can be considered as a part of the vehicle interior according to its spatial arrangement, inside which the person arranged at the vehicle position usually performs activities, for example office activities such as writing, reading, activities with respect to the use of mobile devices such as laptops, etc.

[0044] A closed-loop vehicle control device may be understood to mean a device which senses, determines or receives information about the state of the vehicle. Typically, the closed-loop vehicle control device is connected to a vehicle bus system, using which the closed-loop vehicle control device is indirectly connected to different component parts of the vehicle, such as sensors, actuators, etc. The closed-loop vehicle control device is configured to provide information to the closed-loop lighting system control device, so that at least a specific vehicle state can be identified based on this information.

[0045] In the present case, a lighting mode can be understood to mean a mode of the lighting system in which, in principle, light output by at least one lighting system lamp device is possible. The lighting system can be operated in a lighting mode, specifically allowing for the ability to illuminate at least one working area based on at least one lamp device.

[0046] Optionally, the vehicle status information may include in particular the ignition status of the vehicle and the vehicle speed. This may ensure a closed-loop control of the lighting system, in particular taking into account the actual use and / or movement of the vehicle, with the result that the influence on the user may help the user to focus according to the use and / or movement of the vehicle.

[0047] The lighting system can be controlled based on the ignition state of the vehicle with respect to the use of the vehicle. Since the ignition state generally indicates whether a user is disposed in the vehicle, the vehicle ignition state is advantageously taken into account. Detecting the vehicle ignition state is in particular helpful in defining a lighting mode in this respect.

[0048] Vehicle speed may be used as a measure of whether a vehicle user generally directs their attention toward the vehicle's surroundings, and thus lighting of the at least one working area may help the user focus their attention.

[0049] First, the closed-loop lighting system control device is configured to automatically terminate the lighting of the working area if the closed-loop lighting system control device recognizes a vehicle movement at a vehicle speed greater than a predetermined first speed threshold based on the received vehicle state information. Therefore, once the vehicle moves at a vehicle speed greater than or equal to the first speed threshold, the lighting of the working area is automatically terminated. In particular, when the vehicle moves accordingly, this helps the user not to be affected by the lighting system and the user turns their attention to the surroundings of the vehicle. Therefore, user comfort is improved.

[0050] Alternatively, the closed-loop lighting system control device may also be configured to automatically terminate the lighting of the working area if the closed-loop lighting system control device recognizes vehicle motion (independent of vehicle speed) based on the received vehicle state information. According to this embodiment, the lighting of the working area is automatically terminated as soon as the vehicle is moving. In particular, when the vehicle is moving, this prevents the user from being affected by the lighting system, and the user turns their attention to the surroundings of the vehicle. Therefore, user comfort can be improved.

[0051] In another alternative, the closed-loop lighting system control device can also be configured to automatically terminate the lighting of the work area when the vehicle ignition status changes in a specific manner. For example, if the received vehicle information is unacceptable regarding the ignition status or if the ignition status is unknown or cannot be determined based on the received vehicle information, lighting can be prevented. Subsequently, the user is helped by maintaining focus.

[0052] In some embodiments, at least one light device is arranged and configured so as to ensure an illumination of at least 400 lux (lumens / square meter) for at least one working area. Such a high illumination corresponds to the minimum illumination usually selected for fixed working areas (e.g. in an office). In other words, the lighting system ensures that the lighting intensity corresponds to the lighting intensity of a fixed working environment. This improves user comfort, especially in the case of visual-based activities in a vehicle.

[0053] Optionally, at least one additional working area in the vehicle can be illuminated by at least one light device. This additionally increases user comfort. Firstly, the at least one additional working area can include at least the area of ​​the instrument panel and / or the steering device or can be defined by such areas with respect to their spatial arrangement.

[0054] As an alternative or in addition, further working areas defined by the first and / or further vehicle row of seats can be illuminated by the lighting system. This again increases user comfort.

[0055] Optionally, the lighting system comprises at least one further light device. As a result, a need-based arrangement of the lighting system light devices can be selected such that shadows in the at least one working area are reduced. Alternatively or in addition, a need-based arrangement of the lighting system light devices can also be selected such that a user's preferred lighting is comfortably maintained.

[0056] First, the lighting system may include a plurality of light devices and the light devices may be arranged to minimize (optimize) shadows in at least one working area. Alternatively or in addition, the lighting system light devices may be selected to be arranged based on needs so that the comfort of the user is maintained.

[0057] Optionally, at least one lighting system light device is arranged such that a light beam emitted by the at least one light device is prevented from directly impinging on the eyes of a user in the first row of vehicle seats, at least insofar as the user adopts a normal position in the first row of vehicle seats.

[0058] In some embodiments, the light devices can ensure different illumination levels. As a result, the illumination level in at least one working area can be matched to the arrangement of the light devices.

[0059] If the first row of vehicle seats has a plurality of work areas, the lighting system can preferably be configured based on the at least one light device to symmetrically illuminate the plurality of first row vehicle seat work areas. For example, the plurality of work areas can correspond to a work area assigned to the driver's position and a work area assigned to the front passenger position. The lighting system can then ensure a symmetrical lighting pattern for the work areas arranged next to each other. This provides equal user comfort for all users in the first row of vehicle seats.

[0060] Alternatively, a single working area which can be illuminated symmetrically by the lighting system with regard to the lateral extent (through the longitudinal axis of the vehicle) can also be defined by the driver's position and the front passenger's position.

[0061] Optionally, the illumination provided by the different lighting system lamp devices can be adjusted according to the illuminated part of the vehicle interior. In particular, the illumination adjustment can be provided by a closed-loop lighting system control device. The illumination modification provided by the different lighting system lamp devices allows the reduction and in particular minimization of shadows in certain parts of the vehicle interior. The user comfort is thus additionally increased.

[0062] In some embodiments, the lighting system includes a human-machine interface. Subsequently, the lighting system is configured so that in the lighting mode of the lighting system, the lighting of at least one working area by at least one light device can be re-enabled based on a user input received by the human-machine interface. This means that the lighting of at least one working area can be repeatedly ensured even after automatic termination. This only requires user input, which can improve user comfort.

[0063] Firstly, the lighting of the at least one working area can be reactivated only when it is identified based on the vehicle status information received by the closed-loop lighting system control device that the vehicle speed is less than a predetermined second speed threshold. This advantageously ensures that the user is not affected by the lighting of the at least one working area as long as the moving speed of the vehicle is greater than the second speed threshold. This can lead to an additional improvement in user comfort.

[0064] Optionally, the first speed threshold and the second speed threshold may be the same. Alternatively, the first speed threshold and the second speed threshold may be different, so that hysteresis may be taken into account.

[0065] Optionally, a corresponding user input via the human-machine interface may be blocked as long as a vehicle speed less than a second speed threshold is not detected.

[0066] In an alternative, a corresponding user input via the human-machine interface may have no consequences as long as a vehicle speed less than the second speed threshold is not detected.

[0067] In another alternative, user input via the human machine interface may be blocked or have no consequence unless it is identifiable that the vehicle is stationary based on the received vehicle status information. In some embodiments, vehicle stationary and / or vehicle motion may be identifiable based on the vehicle status information received by the closed-loop lighting system control device, in which respect the vehicle status information may indicate the vehicle speed.

[0068] Optionally, a lighting mode of the lighting system may be enabled based on user input received by the human machine interface and / or based on vehicle status information received by the closed-loop lighting system control. In this context, the vehicle status information may specify a vehicle ignition state. This creates the option of placing the lighting system in a specific lighting mode based on manual user input or automatically based on received vehicle status information. This may increase user comfort.

[0069] According to one embodiment, the lighting system comprises an enabled lighting mode under the condition that the vehicle ignition is enabled (ignition enabled state). In an alternative embodiment, or in addition, the lighting system comprises an enabled lighting mode under the condition that the vehicle ignition is disabled (ignition disabled state). In another alternative or in addition, the lighting system comprises an enabled lighting mode under the condition that the vehicle has a motor turned on. The vehicle status information may thus also specify the motor status of the vehicle.

[0070] In the enabled lighting mode, the lighting system may be configured to enable lighting of at least one work area. This means that lighting of at least one work area can be initiated in the enabled lighting mode. For example, appropriate user input may be required to actually trigger the lighting.

[0071] In an alternative, the lighting of at least one working area can be automatically initiated when the lighting mode is activated. This means that the lighting of at least one working area is ensured as soon as the lighting mode is activated. This can additionally increase user comfort.

[0072] For example, based on the following status table I, the light emission of at least one lamp device can be blocked or allowed by the closed-loop lighting system control device:

[0073] State Table I: Overview of light emission depending on the vehicle's ignition state and vehicle speed State table I shows that according to rows 1 and 2, light emission of at least one lighting system lamp device is blocked because the vehicle state information received by the closed-loop lighting system control device indicates an unknown or unacceptable ignition state of the vehicle. Therefore, lighting of at least one working area is prevented in that case because the lighting system has a deactivated lighting mode.

[0074] State table 1 further shows that according to row 3, light emission of at least one lighting system light device is blocked because, although the vehicle status information received by the closed-loop lighting system control device indicates an activated ignition state of the vehicle, alternatively indicates initiation of vehicle ignition, or further alternatively indicates an appropriate user input, the received vehicle status information additionally indicates a vehicle speed of 4 km / h or more. In this case, the first speed threshold is 4 km / h. In that case, the lighting system has an activated lighting mode, but light emission is blocked because the vehicle speed is greater than or equal to the first speed threshold. If lighting is actually initiated first and the actual vehicle speed only exceeds the first speed threshold at a later time, this then leads to an automatic termination of lighting. Thus, lighting of at least one working area is prevented in that case. Thus, the user's concentration is maintained.

[0075] State table I further shows that according to row 4, light emission of at least one lighting system lamp device is permitted because firstly the vehicle state information received by the closed-loop lighting system control device indicates an activated ignition state of the vehicle, alternatively indicates initiation of vehicle ignition, or further alternatively indicates an appropriate user input, and secondly the received vehicle state information furthermore indicates that the vehicle speed is less than 4 km / h (less than the first speed threshold). Therefore, in that case the lighting of at least one working area is permitted. Therefore, user comfort can be improved in this activated lighting mode of the lighting system.

[0076] Furthermore, the state table 1 shows that according to row 5, light emission of at least one lighting system lamp device is permitted because the vehicle state information received by the closed-loop lighting system control device indicates a deactivated ignition state of the vehicle. Thus, in that case, illumination of at least one working area is permitted, independently of the received vehicle state information indicating that the vehicle speed is below a predetermined threshold value. If a deactivated ignition state is determined, a lighting mode of the lighting system is enabled independently of the vehicle speed. This can increase user comfort.

[0077] In particular, the closed-loop lighting system control device can be particularly configured to ensure the state of the state table I.

[0078] Optionally, the enabled lighting mode of the lighting system may also be deactivated based on received vehicle information. For example, the received vehicle information may include a state of charge of an energy storage device in the vehicle. In that case, the vehicle information may indicate a low energy storage device state of charge. Therefore, if the energy storage device state of charge drops below a charge threshold, the enabled lighting mode of the lighting system may be deactivated by the closed-loop lighting system control device. This may ensure that the lighting system does not reduce the state of charge of the energy storage device in the vehicle.

[0079] According to another aspect, some embodiments also relate to a method for operating a lighting system of a vehicle. The lighting system includes at least one light device arranged in the area of ​​an interior roof lining of the vehicle. The lighting system includes a closed-loop lighting system control device connected to a closed-loop vehicle control device of the vehicle. The method includes at least the following steps: In a lighting mode of the lighting system, a working area defined by at least a first row of vehicle seats of the vehicle is illuminated.

[0080] Vehicle status information is transmitted from the closed-loop vehicle control unit to the closed-loop lighting system control unit.

[0081] In the lighting mode of the lighting system, lighting of at least one working area is automatically terminated based on the received vehicle status information.

[0082] The advantages achieved by the lighting system as explained here are also ensured in a corresponding manner by the method as described here.

[0083] The features explained above with respect to the lighting system arrangement should be transferred accordingly to the method described here.

[0084] According to another aspect, some exemplary embodiments also relate to a vehicle having a lighting system as described herein.The advantages achieved by the lighting system as explained herein are also ensured in a corresponding manner by the vehicle as described herein.

[0085] In the sense of the present disclosure, a vehicle may in particular include a vehicle that is at least partially electrically driven. In particular, a vehicle may include land vehicles, in particular all-terrain vehicles, and road vehicles, such as cars, buses, trucks and other commercial vehicles. The vehicle may be manned or unmanned. In addition to pure electric vehicles (BEV), hybrid electric vehicles (HEV) and plug-in hybrid electric vehicles (PHEV) may also be included.
