DETAILED DESCRIPTION
Examples of the present disclosure relate to controlling lighting on a vehicle. Some examples of the present disclosure relate to controlling lighting and/or lights/light sources on and/or around a door of a vehicle.
In examples, a controller of a vehicle, such as a vehicle system controller, determines that a door of the vehicle is not closed. For example, the vehicle system controller may receive signals from one or more sensors to determine that a door of the vehicle is not closed.
In some examples the controller activates lighting means on the vehicle door and/or in an aperture corresponding to the vehicle door in dependence on the determination that the vehicle door is not closed.
For example, the controller may control a plurality of light sources/lights on the vehicle door and/or in an aperture corresponding to the vehicle door to illuminate when it is determined that the vehicle door is not closed.
In examples, the controller determines that the door of the vehicle has been not closed for a period of time greater than a predetermined time period.
The controller may control the lighting means in dependence on the determination that the door of the vehicle has been not closed for a period of time greater than the pre-determined time period. For example, the controller may increase the luminous intensity and/or change \ — the colour of the lighting means. Additionally or alternatively the controller may vary the luminous intensity of the lighting means with time.
A technical effect of at least some examples of the disclosure is that lighting means on the door, which may be different to a door ajar lamp, can be intelligently controlled to draw attention to a vehicle door that is not closed which provides safety benefits.
Furthermore, examples of the disclosure provide for an indication to other road users that occupants of a vehicle may have exited the vehicle and may therefore be present in the vicinity of the vehicle or in the road.
Some of the features referred to in the discussion of Figs. 1 to 4 can be found in Figs. 5 to 7.
Fig. 1 illustrates an example of a vehicle system controller 10. In examples, the vehicle system controller 10 of Fig. 1 may be a chip or a chip set.
The vehicle system controller 10 may form part of one or more vehicle systems 24 comprised in a vehicle 14, such as the one illustrated in the example of Fig. 2.
Implementation of a controller 10 may be as controller circuitry. The controller 10 may be implemented in hardware alone, have certain aspects in software including firmware alone or can be a combination of hardware and software (including firmware).
As illustrated in Fig. 1 the controller 10 may be implemented using instructions 34 that enable hardware functionality, for example, by using executable instructions 34 of a computer program 26 in a general-purpose or special-purpose processor 28 that may be stored on a computer readable storage medium (disk, memory etc) to be executed by such a processor 28.
The processor 28 is configured to read from and write to the memory 30. The processor 28 may also comprise an output interface via which data and/or commands are output by the processor 28 and an input interface via which data and/or commands are input to the processor 28.
\ —
The memory 30 stores a computer program 26 comprising computer program instructions 34 (computer program code) that controls the operation of the controller 10 when loaded into the processor 28. The computer program instructions 34, of the computer program 26, provide the logic and routines that enables the apparatus to perform the methods illustrated in Figs 3 and 4. The processor 28 by reading the memory 30 is able to load and execute the computer program 26.
The controller 10 therefore comprises:
at least one processor 28;and at least one memory 30 including computer program code the at least one memory 30 and the computer program code configured to, with the at least one processor 28, cause the controller 10 at least to perform:
determining that a door of a vehicle is not closed;
activating lighting means on the vehicle door and/or in an aperture corresponding to the vehicle door in dependence on the determination that the vehicle door is not closed;
determining that the door of the vehicle has been not closed for a period of time greater than a pre-determined time period; and controlling the lighting means in dependence on the determination that the door of the vehicle has been not closed for a period of time greater than the pre-determined time period.
As illustrated in Fig 1, the computer program 26 may arrive at the controller 10 via any suitable delivery mechanism 32. The delivery mechanism 32 may be, for example, a nontransitory computer-readable storage medium, a computer program product, a memory device, a record medium such as a compact disc read-only memory (CD-ROM) or digital versatile disc (DVD), an article of manufacture that tangibly embodies the computer program 26. The delivery mechanism may be a signal configured to reliably transfer the computer program 26. The controller 10 may propagate or transmit the computer program 26 as a computer data signal.
Although the memory 30 is illustrated as a single component/circuitry it may be implemented as one or more separate components/circuitry some or all of which may be integrated/removable and/or may provide permanent/semi-permanent/ dynamic/cached storage.
\ —
Although the processor 28 is illustrated as a single component/circuitry it may be implemented as one or more separate components/circuitry some or all of which may be integrated/removable. The processor 28 may be a single core or multi-core processor.

As used herein, the context of the vehicle 14 is intended to include any information of the situation and/or environment of the vehicle and/or one or more passengers of the vehicle before, during and/or after determination that a door 12 of the vehicle 14 is not closed.
In examples, determining context information of the vehicle 14 comprises retrieving information from the memory 30 such as map/terrain/location/speed limit information.
In some examples, determination of the context of a vehicle 14 may comprise at least one of: determining whether a collision event involving the vehicle 14 has occurred within a predetermined time period prior to the vehicle door 12 becoming not closed, determining whether an emergency stop signal has occurred in the vehicle 14 within a predetermined time period prior to the vehicle door 12 becoming not closed, determining whether an emergency braking system, automatic (such as an anti-lock braking system) or nonautomatic, has been activated within a predetermined time period prior to the vehicle door 12 becoming not closed, determining the maximum speed of the vehicle 14 within a predetermined time period prior to the vehicle door 12 becoming not closed and determining the speed limit at the location of the vehicle 14.
In examples, the pre-determined time period relating to a time period prior to the vehicle door 12 becoming not closed may be referred to as a context pre-determined time period. The context pre-determined time period may be distinct from and/or different to the predetermined time period discussed in relation to block 306 of Fig. 3.
In examples, any suitable context pre-determined time period may be used. For example, a context predetermined time period of 1 or more seconds or greater may be used. In examples a context predetermined time period of less than 1 second may be used.
Furthermore, in some examples, different context predetermined time periods may be used in relation to different contexts. For example, a different context predetermined time period may be used in relation to a collision event determination compared to an emergency stop signal determination and so on.
For example, a context predetermined time period in the range 0 > context predetermined time period <= 1800 seconds for assessment of a collision event and/or 0 > context pre21 \ — determined time period <= 60 seconds for assessment of maximum speed prior to the vehicle door 12 becoming not closed may be used and so on.
Additionally or alternatively, the context pre-determined time period may be monitored in relation to the vehicle coming to a stop.
In the example of Fig. 4 method 400 comprises, at block 408, controlling the lighting means 18 in dependence on the determined context of the vehicle 14.
For example, controlling lighting means 18 may comprise controlling the luminous intensity and/or colour and/or frequency of time variation of the lighting means 18 in dependence on the determined context 16 of the vehicle 14.
For example, the frequency of time variation may be higher if an emergency context 16 is determined and slower if a non-emergency context 16 is determined. In some examples the frequency may be higher in a non-emergency context 16 compared with an emergency context 16.
In examples where it is determined that a collision event has occurred within the context predetermined time period prior to the door 12 becoming not closed the lighting means 18 may be controlled to illuminate with an intensity which varies with time at a frequency in the range 3 to 4 Hz.
Additionally or alternatively, in the example of Fig. 4, method 400 comprises, at block 410, controlling lighting means 18 to adopt the determined original state in the absence of a determination that the vehicle door 12 is not closed.
For example, vehicle system controller 10 may be configured to control the lighting means 18 to return to the original state upon the determination that the vehicle door 12 has been closed.

In the example of Fig. 7, the lighting means 18 are controlled to flash to further draw attention to the door 12 not being closed and also to indicate that the situation is potentially unsafe.
\ —
Furthermore, at part B and/or C of Fig. 7 the context 16 of the vehicle 14 has been determined and it has been determined that an emergency braking event has happened within, for example, a time period of 30 seconds prior to the door 12 being opened.
For example, one or more sensors 36 in the vehicle 14a may have been used to make the determination. Additionally or alternatively, one or more transceivers 38 may, in some examples, be used to receive information from the vehicle 14b that has experienced the collision event allowing the vehicle 14a to the rear to determine that a vehicle collision event has occurred prior to the door 12 being opened further allowing the context 16 of the vehicle 14a to be determined.
Control of the lighting means 18 at part D of Fig. 7 may be performed in dependence on the determined context of the vehicle. In the example of Fig. 7 the frequency of time variation is selected in dependence on the determined context of the vehicle 14.
Accordingly, in this way, the vehicle system controller 10 of the vehicle 14 has intelligently controlled the lighting means 18 in the door 12 to provide increased safety benefits.
