Description

Technical Field

[0001] This application relates to the field of automotive technology, and in particular to a brightness control method, device, electronic device, and storage medium based on multiple scenarios. Background Technology

[0002] With the rapid advancements in automotive technology, automobiles have gradually transcended their definition as mere transportation tools, evolving into intelligent mobility platforms integrating numerous functions. In this context, the comfort of the in-car environment has become a crucial factor that cannot be ignored, especially brightness adjustment devices such as interior lighting and sunshades, which play a vital role in enhancing the driving and riding experience. These devices precisely regulate light intensity to create a comfortable and pleasant riding environment for passengers.

[0003] Currently, common automotive interior brightness adjustment devices, such as reading lights, dome lights, and sunroof sunshades, primarily rely on automatic switching or manual adjustment of brightness and opening degree for control. However, in practical applications, this traditional control method exhibits certain limitations, especially during driving. If the driver is distracted by adjusting the brightness adjustment devices, it may increase the risk of traffic accidents. Furthermore, existing control strategies fail to fully meet the refined lighting environment requirements of intelligent vehicles in different usage scenarios in coordinating interior lighting and brightness adjustment devices. This deficiency not only affects the convenience and intelligence of adjustment but may also potentially have adverse effects on the visual health of drivers and passengers due to the inability to adapt to the optimal light intensity in various scenarios. Therefore, the control strategies and intelligence aspects of existing in-vehicle brightness adjustment devices require further optimization and improvement. Summary of the Invention

[0021] It should be noted that the automobiles in this application embodiment refer to automobiles that use new energy sources (non-traditional petroleum and diesel energy) and possess advanced technologies. These automobiles employ new power systems that can effectively reduce vehicle emissions, minimize environmental impact, and improve energy efficiency. The new energy vehicles in this application embodiment include, but are not limited to, the following types of automobiles: electric vehicles (EVs), battery electric vehicles (BEVs), fuel cell electric vehicles (FCEVs), plug-in hybrid electric vehicles (PHEVs), and hybrid electric vehicles (HEVs).

[0022] The following describes in detail, with reference to the accompanying drawings, a brightness control method, apparatus, electronic device, and storage medium based on multiple scenarios according to embodiments of this application.

[0023] Figure 1 This is a flowchart illustrating a brightness control method based on multiple scenarios provided in an embodiment of this application. Figure 1 The multi-scenario-based brightness control method can be executed by the vehicle controller of new energy vehicles. For example... Figure 1 As shown, the method includes:

[0024] S101, real-time acquisition of the interior light intensity value of the vehicle, and acquisition of the location information of the occupants inside the vehicle;

[0025] S102, Based on the location information, obtain the scene dependency information corresponding to the occupant's location, and based on the scene dependency information, determine the target scene where the occupant is located;

[0026] S103, Determine the target illumination intensity value based on the target scene;

[0027] S104, obtain the road segment type where the vehicle is currently located, and determine the light intensity buffer value based on the road segment type;

[0028] S105 controls the vehicle's brightness adjustment device based on the in-vehicle light intensity value, location information, light intensity buffer value, and target light intensity value, so as to adjust the brightness inside the vehicle.

[0029] Light intensity buffer value: This can be used to measure factors that hinder light from reaching a target vehicle. For example, urban road sections with many obstructions and buildings cause greater interference that hinders light from reaching the target vehicle, while open highway sections with no obstructions cause less interference. In other words, the size of the light intensity buffer value can be used to distinguish the strength of external interference; different light intensity buffer values ​​correspond to different levels of external interference.

[0030] As an example, when external interference is weak, such as in a cloudless, flat highway scene without obstacles or obstructions (Type 1), the light intensity buffer value can be small (indicating less light attenuation), indicating good lighting conditions and minimal impact from external interference. Conversely, when external interference is strong, such as in an urban road scene with tall buildings, complex roads, and numerous overpasses (Type 1), the light intensity buffer value can be large (indicating greater light attenuation), indicating poor lighting conditions and significant impact from external interference. In short, the light intensity buffer value changes with the intensity of external interference; the weaker the external interference, the smaller the light intensity buffer value; conversely, the stronger the external interference, the larger the light intensity buffer value.

[0031] The introduction of a light intensity buffer is mainly to avoid fluctuations in the light intensity value collected by the light intensity sensor due to its own sensitivity and external interference, thereby avoiding frequent or even repeated adjustments by the brightness adjustment device.

[0032] It is understandable that the specific value of the light intensity buffer can vary with the vehicle's operating status, changes in hardware equipment, and changes in the external environment. The specific value can be calculated by the vehicle controller based on the above parameters, or it can be set by the user. No specific limitation is made here.

[0033] In one example, after starting the target vehicle, the user can enable / disable the "scene-based automatic brightness adjustment device function". During the driving process of the target vehicle, the indoor light intensity value will change with the change of the external lighting environment. If the user enables the "scene-based automatic brightness adjustment device function" after starting the target vehicle, the vehicle controller will use the light sensor configured in the vehicle to collect the indoor light intensity value in real time, and obtain the position information of the occupants in the vehicle (front row or rear row) through the high-definition camera equipment configured in the vehicle or the sensors configured in each seat.

[0034] Furthermore, after determining the occupant's location within the vehicle, scene-dependent information can be collected using the vehicle's high-definition cameras or sensors to determine the occupant's current target scene. For example, if a high-definition camera detects that the occupant is reading, it can be determined that the passenger is in a reading scene; if a sensor detects that a movie is playing on the rear entertainment screen, and a high-definition camera detects that the passenger is looking at the entertainment screen, it can be determined that the passenger is in an entertainment scene. After determining the occupant's target scene, the corresponding target light intensity value (the optimal light intensity value for the scene) can be queried.

[0035] Furthermore, based on the type of road segment the vehicle is currently on, a light intensity buffer value is determined. Then, using the target light intensity value as the adjustment target, the brightness adjustment device at the location of the occupants is controlled so that the interior light intensity value at the location of the occupants is within the range of the target light intensity value.

[0036] This application embodiment acquires the in-vehicle light intensity value and the location information of the occupants in real time; based on the location information, it acquires scene dependency information corresponding to the occupant's location, and determines the target scene where the occupant is located based on the scene dependency information; based on the target scene, it determines the target light intensity value; it acquires the road segment type where the vehicle is currently located, and determines the light intensity buffer value based on the road segment type; based on the in-vehicle light intensity value, location information, light intensity buffer value, and target light intensity value, it controls the vehicle's brightness adjustment device to adjust the brightness inside the vehicle. This application can adapt the optimal light intensity value according to the specific usage scenario of the occupants, and automatically control the brightness adjustment device to make the in-vehicle light intensity value reach the optimal light intensity value corresponding to the scene, improving driving safety and enhancing the occupant's user experience.

[0037] In some embodiments, after acquiring the in-vehicle light intensity value in real time, the method further includes: determining the real-time light intensity change rate of the vehicle within a preset period based on the in-vehicle light intensity value; if the real-time light intensity change rate is less than or equal to a preset light intensity change coefficient, then determining that the brightness adjustment device is in an automatically controllable state; if the real-time light intensity change rate is greater than the preset light intensity change coefficient, then determining that the brightness adjustment device is in a non-automatically controllable state.

[0038] Specifically, the rate of change of light intensity indicates the extent of change in the light intensity inside a vehicle over a period of time or over a distance.

[0039] Light intensity variation coefficient: This parameter is introduced to prevent the brightness adjustment device of a target vehicle from continuously moving in specific scenarios, such as when the target vehicle passes under obstacles like bridges or large billboards, or when a car enters / exits a short tunnel. In these situations, the light intensity may change significantly within a short period. If the brightness adjustment device is adjusted under these conditions, it will move repeatedly, greatly increasing its workload and potentially causing the motor to overheat. By setting the light intensity variation coefficient, the repeated movement of the brightness adjustment device can be effectively controlled and adjusted, preventing it from moving repeatedly in these scenarios and reducing the risk of motor overheating.

[0040] As an example, after acquiring the real-time light intensity value inside the vehicle, the real-time light intensity change rate of the vehicle within a preset period can be determined. Specifically, the vehicle's light intensity value at the first and second times within the preset period can be collected and calculated to determine whether the target vehicle is in the aforementioned scenario.

[0041] The first and second times refer to two points in time within a preset period for collecting the light intensity value inside the vehicle. For example, if the preset period is 3 seconds, the first time could be second 0, and the second time could be second 3. The vehicle's light sensor will then collect the first light intensity value at second 0 and the second light intensity value at second 3, and calculate the rate of change of light intensity for the target vehicle using these values. This calculation can be performed using the following method:

[0042] Light intensity change rate = (first light intensity value - second light intensity value) / first light intensity value;

[0043] At this point, the preset period is set to 3 seconds. Assuming the target vehicle enters a dimly lit tunnel section from a bright outdoor environment at time 0, the first illuminance value collected at time 0 is 100. After entering the tunnel, the second illuminance value collected at time 3 is 40. The rate of change of illuminance can then be calculated.

[0044] The rate of change of light intensity is 1 = (100-40) / 100 = 0.6;

[0045] Furthermore, within the next 3 seconds (the 6th second), the vehicle's light intensity value can be collected again. Assume the light intensity changes to 40 at this point. The rate of change of light intensity can then be calculated:

[0046] The rate of change of light intensity 2 = (40-40) / 40 = 0;

[0047] If, in the next 3 seconds (the 6th second), the light intensity value of the vehicle is 100, then the rate of change of light intensity can be calculated:

[0048] The rate of change of light intensity is 2 = (40-100) / 40 = 1.5;

[0049] It is understood that the above judgment logic applies both when the target vehicle enters and exits the tunnel, and it applies to both day and night. Furthermore, the preset cycle time can be set according to actual needs and is not specifically limited here.

[0050] The preset light intensity change coefficient is a pre-set value used to determine if the light intensity changes too rapidly. If the light intensity change rate is less than or equal to the preset coefficient, it indicates that the light intensity in the target vehicle's environment is changing slowly, and the brightness adjustment device can be put into an automatic controllable state, allowing it to operate automatically. If the light intensity change rate is greater than the preset coefficient, it indicates that the light intensity in the target vehicle's environment is changing rapidly. In this case, if the brightness adjustment device is in an automatic controllable state, it will continuously rotate, leading to problems such as motor overheating. Therefore, the brightness adjustment device should be put into a non-automatic controllable state, meaning the automatic adjustment function will not work.

[0051] Continuing with the previous example, the rate of change of light intensity when the vehicle first enters the tunnel is 1 = (100-40) / 100 = 0.6. If the preset value of the light intensity change coefficient is 0.3, then the rate of change of light intensity when the target vehicle first enters the tunnel is 0.6, which is greater than 0.3. This indicates that the external light intensity value changes too quickly. At this time, the brightness adjustment device is in an uncontrollable state, and the automatic adjustment function will not work.

[0052] Furthermore, during the second cycle (3 seconds to 6 seconds), the light intensity change rate 2 = (40-40) / 40 = 0, that is, the light intensity change rate of the target vehicle is less than 0.3. At this time, the brightness adjustment device is in an automatically controllable state and will adjust the position of the brightness adjustment device according to the change of light intensity.

[0053] If the light intensity change rate 2 = (40-100) / 40 = 1.5; that is, the light intensity change rate of the target vehicle 1.5 is greater than 0.3, the brightness adjustment device will continue to be in an uncontrollable state, and the automatic adjustment function will not work.

[0054] This embodiment determines whether the brightness adjustment device is in an automatically controllable state or not based on a real-time comparison of the preset light intensity change coefficient and light intensity change rate. This can prevent the brightness adjustment device from repeatedly moving in road sections with large light changes, reduce excessive wear and tear on the device, improve the user experience, and enhance driving safety.

[0055] Furthermore, in some embodiments, the target scene includes at least an office scene, a meeting scene, a reading scene, and an entertainment scene; determining the target illumination intensity value based on the target scene includes: determining the target illumination intensity value corresponding to the target scene based on the mapping relationship between the scene and the illumination intensity value.

[0056] Specifically, the target scenarios encountered by occupants within the vehicle include at least office scenarios, meeting scenarios, reading scenarios, and entertainment scenarios. It is understood that users can also add target scenarios according to their needs. Furthermore, after setting different target scenarios in the vehicle, the optimal illuminance value (target intensity value) corresponding to the relevant target scenario can be found in the professional manual GB / T 26189-2010 "Lighting for Indoor Workplaces". This value is then mapped one-to-one with the target scenario and set within the vehicle's overall system. When the "Scene-Based Automatic Brightness Adjustment Device Function" is activated and the target scenario is determined, the vehicle will retrieve the target illuminance value corresponding to the target scenario from the preset mapping relationship.

[0057] It is understandable that the optimal illumination value (target illumination value) for the target scene can also be set by the user, and the relevant crew members can also change the already determined target illumination value. The specific method is not limited here.

[0058] As an example, the mapping relationship of target illumination intensity values ​​in common scenarios is as follows:

[0059] Office Scenario: Offices typically require adequate lighting to ensure occupant comfort and work efficiency. Target light intensity for offices can be between 300 and 500 lux.

[0060] Meeting Scenario: The lighting in the meeting room needs to allow participants to clearly see each other and the materials in the room. The target illuminance value can be between 500 and 700 lux.

[0061] Reading Scenarios: In reading scenarios, higher light intensity is necessary. The target light intensity value can be between 500 and 1000 lux to ensure that the text is clearly visible and to reduce eye strain.

[0062] Entertainment Scenarios: For entertainment scenarios, lighting intensity is typically lower to provide a better viewing experience. Target lighting intensity values ​​can be between 50 and 200 lux.

[0063] This embodiment allows different target scenes to be pre-set in the vehicle, and the target illumination intensity value corresponding to the target scene is determined based on the mapping relationship between the scene and the illumination intensity value. This enables occupants to set personalized target scenes according to their needs to meet daily life requirements. At the same time, the corresponding target illumination intensity value is determined based on the target scene, and the illumination intensity value inside the vehicle is adjusted according to the target scene during driving, improving the intelligent experience of the vehicle cabin.

[0064] In addition, in some embodiments, controlling the vehicle's brightness adjustment device based on the in-vehicle light intensity value, location information, light intensity buffer value, and target light intensity value includes: determining a first target value and a second target value based on the in-vehicle light intensity value and the light intensity buffer value; and controlling the vehicle's brightness adjustment device based on the location information, the first target value, the second target value, and the target light intensity value.

[0065] Specifically, after determining the specific value of the light intensity buffer value, the vehicle controller can obtain the first target value and the second target value based on the collected in-vehicle light intensity value and the light intensity buffer value through the following calculation method:

[0066] First target value = In-vehicle light intensity value - Light intensity buffer value;

[0067] Second target value = In-vehicle light intensity value + Light intensity buffer value;

[0068] Furthermore, the first and second target values ​​are calculated and compared with the target light intensity value, and the brightness adjustment device at the occupant's location is controlled according to the table results.

[0069] In some embodiments, the location information includes front row position and rear row position, and the brightness adjustment device includes a front row adjustment device and a rear row adjustment device; based on the comparison result of the location information, a first target value, a second target value, and a target illuminance value, the brightness adjustment device of the vehicle is controlled, including: if the occupant is in the front row position and the first target value is greater than the target illuminance value, then the front row adjustment device is controlled to turn off; if the occupant is in the front row position and the second target value is less than the target illuminance value, then the front row adjustment device is controlled to turn on; if the occupant is in the rear row position and the first target value is greater than the target illuminance value, then the rear row adjustment device is controlled to turn off; if the occupant is in the rear row position and the second target value is less than the target illuminance value, then the rear row adjustment device is controlled to turn on; when the target illuminance value is greater than or equal to the first target value and less than or equal to the second target value, then the control of the brightness adjustment device is stopped.

[0070] Specifically, as an example, if the real-time in-vehicle illumination intensity value obtained by the vehicle controller is 100, and the illumination intensity buffer value is determined to be 10 based on the road segment type, and the passenger is sitting in the back watching a movie, it can be determined that the passenger is in an entertainment scene, and the corresponding target illumination intensity value of 70 can be obtained by querying the mapping relationship.

[0071] In addition, it should be noted that the brightness adjustment device of the vehicle has an adjustment range of 0-100. When the brightness adjustment device is 0, it means that the brightness adjustment device is completely off. When the brightness adjustment device is 100, it means that the brightness adjustment device is fully on. When the brightness adjustment device is 50, it means that the brightness adjustment device is half on.

[0072] At this point, the first target value = 100 - 10 = 90;

[0073] Second target value = 100 + 10 = 110;

[0074] If the logic condition that the first target value of 90 is greater than the target light intensity value of 70 is met, it means that the light intensity value inside the vehicle is too high and needs to be reduced to reach the target light intensity value. The rear seat adjustment device can be turned off.

[0075] Furthermore, the vehicle controller can continue to collect the light intensity value of the rear seats inside the vehicle. If the light intensity value inside the vehicle is 75 at this time...

[0076] First target value = 75 - 10 = 65;

[0077] Second target value = 75 + 10 = 85;

[0078] At this point, the logical condition that the target light intensity value 70 is between the first target value 65 and the second target value 85 is met, and the rear row adjustment device can be controlled to stop at the current position and maintain this state unchanged.

[0079] Further, continue to collect the light intensity value of the rear row inside the vehicle. If the light intensity value of the rear row inside the vehicle is 40 at this time.

[0080] First target value = 50 - 10 = 40;

[0081] Second target value = 50 + 10 = 60;

[0082] At this point, the logical condition that the second target value of 60 is less than the target light intensity value of 70 is met. This indicates that the light intensity inside the vehicle is too low and needs to be increased to reach the target light intensity value. The rear seat adjustment device can then be activated. When the logical condition that the target light intensity value is between the first and second target values ​​is met, the rear seat adjustment device can be stopped at its current position (if it is at half position, the brightness adjustment device will be activated at half level), and this state will remain unchanged.

[0083] This embodiment controls the brightness adjustment device based on the comparison results of the first target value and the target light intensity value, as well as the comparison results of the second target value and the target light intensity value. Thus, after determining the target scene, the brightness adjustment device can be controlled in a timely manner according to the changes in the light intensity inside the vehicle and the location of the occupants, so as to adjust the light intensity inside the vehicle and keep the light intensity inside the vehicle within the range of the target light intensity corresponding to the target scene, thereby effectively improving the driving comfort of the occupants.

[0084] Furthermore, in some embodiments, the front row adjustment device includes a first front row priority device and a second front row priority device, and the rear row adjustment device includes a first rear row priority device and a second rear row priority device; controlling the front row adjustment device to close includes: first controlling the second front row priority device to close, and then controlling the first front row priority device to close; controlling the front row adjustment device to open includes: first controlling the first front row priority device to open, and then controlling the second front row priority device to open; controlling the rear row adjustment device to close includes: first controlling the second rear row priority device to close, and then controlling the first rear row priority device to close; controlling the rear row adjustment device to open includes: first controlling the first rear row priority device to open, and then controlling the second rear row priority device to open.

[0085] Specifically, the front row adjustment devices include a first front row priority device and a second front row priority device, and the rear row adjustment devices include a first rear row priority device and a second rear row priority device. It is understood that the priority of the adjustment devices can be preset by the vehicle or set by the occupants themselves, without further specific limitations.

[0086] As an example, the brightness adjustment devices in the vehicle include sunroof sunshades and reading lights. The sunroof sunshades include front sunroof sunshades and rear sunroof sunshades, and the reading lights include front reading lights and rear reading lights. The sunroof sunshades indicate natural light priority, and the reading lights indicate reading light priority. If an occupant is in the rear seat of the vehicle and selects natural light priority, then the rear sunroof sunshades will be the first rear-seat priority device, and the rear reading lights will be the second rear-seat priority device.

[0087] If it is necessary to turn on the rear seat adjustment device to increase the light intensity inside the vehicle, the first rear seat priority device (rear sunroof sunshade) will be turned on first to meet the natural light priority condition selected by the occupants. If the rear sunroof sunshade can meet the target light intensity value corresponding to the target scenario after it is turned on, the second rear seat priority device (rear reading light) will not be turned on. If it does not meet the target light intensity value, the second rear seat priority device (rear reading light) will be turned on.

[0088] If it is necessary to turn off the rear seat adjustment devices to reduce the light intensity inside the vehicle, the second rear seat priority device (rear reading lights) will be turned off first to meet the natural light priority condition selected by the occupants. If the target light intensity value corresponding to the target scenario can be met after the rear reading lights are turned off, the first rear seat priority device (rear sunroof sunshade) will not be turned off. If it is not met, the first rear seat priority device (rear sunroof sunshade) will be turned off.

[0089] The control logic of the front row adjustment device is the same as the example above, so it will not be elaborated on here.

[0090] This embodiment enhances the personalized user experience of passengers by providing them with corresponding control requirements for brightness adjustment devices based on their different needs.

[0091] In addition, in some embodiments, a brightness adjustment assistance command input by the passenger is received; based on the brightness adjustment assistance command, the control logic of the first front row priority device, the second front row priority device, the first rear row priority device, and the second rear row priority device is adjusted according to the preset assistance control logic.

[0092] Specifically, continuing from the previous example, if the passenger is in the rear seat and selects natural light priority, they can also choose whether to enable auxiliary control. If the passenger selects auxiliary control, they can input an auxiliary control command. After receiving the auxiliary control command, the vehicle controller will incorporate the front seat adjustment devices into the adjustment process of the rear seat adjustment devices for auxiliary control. The specific control strategy is as follows:

[0093] If it is necessary to activate the rear seat adjustment devices to increase the interior light intensity, the first rear priority device (rear sunroof sunshade) will be activated first, followed by the first front priority device (front sunroof sunshade) to ensure that the occupants' chosen natural light priority is met through auxiliary control. Then, the second rear priority device (rear reading lights) will be activated, and finally, the second front priority device (front reading lights) will be activated.

[0094] If it is necessary to turn off the rear seat adjustment devices to reduce the light intensity inside the vehicle, the second priority front seat device (front reading lights) will be turned off first, followed by the second priority rear seat device (rear reading lights), then the first priority front seat device (front sunroof sunshade), and finally the first priority rear seat device (rear sunroof sunshade).

[0095] It should be noted that, regardless of whether the brightness adjustment device is turned on or off, if the target light intensity corresponding to the target scene can be met after turning on or off the first brightness adjustment device, the control of the subsequent brightness adjustment device will not be executed. The control of the next brightness adjustment device will only be executed if the target light intensity corresponding to the target scene cannot be met after the previous brightness adjustment device is fully turned on or off.

[0096] This embodiment receives brightness adjustment assistance commands input by passengers; based on the brightness adjustment assistance commands, the control logic of the first front row priority device, the second front row priority device, the first rear row priority device, and the second rear row priority device are adjusted according to the preset assistance control logic. Since the adjustment of the control logic can meet the preferences of different passengers, the brightness adjustment assistance commands can provide passengers with personalized assistance control options, greatly improving the passenger's user experience.

[0097] All of the above-mentioned optional technical solutions can be combined in any way to form the optional embodiments of this application, and will not be described in detail here.

[0098] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the process of the embodiments of this application.
